first_img Diamond-based light sources will lay a foundation for quantum communications of the future ( — “We have shown for the first time, theoretically, that a single molecule can behave as a perfect mirror,” Mario Agio tells “Imagine that your mirror at home becomes a single molecule and that you put a strong lens between you and it. Well, you could still see the image of your face reflected…[A]mazing if you think that a molecule is just about a nanometer in size.” This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Agio is a scientist at the Nano-Optics Group headed by Vahid Sandoghdar at ETH Zurich, Switzerland. Sandoghdar’s team investigates both theoretically and experimentally how light interacts with nanoscale objects. “Theoretically,” Agio says, “we show that a directional dipole wave can be reflected by one point-like oscillating dipole.” The results of the work done by the Group, including Gert Zumofen and Nassiredin Mojarad, can be seen in Physical Review Letters: “Perfect Reflection of Light by an Oscillating Dipole.”“There are many possibilities for this kind of work,” Agio points out. He explains that, “Once you can realize efficient coupling between a photon and a molecule or atom in free space, there is a great deal that you can do. For example, advanced solar cells, spectroscopy, quantum communications and quantum computation would all benefit from stronger interaction between light and matter.”However, there are some technical problems that need to be overcome in the lab. One of the more pressing issues is the fact that molecules behave like strongly damped oscillators at room temperature. “We need to cool the system to very low temperatures,” Agio says. Referring to work published earlier this year in Nature Physics (“Efficient coupling of photons to a single molecule and the observation of its resonance fluorescence”), he continues: “Indeed, our experiments have been able to achieve 12 percent extinction of light in the forward direction by a single molecule.Agio also explains that there are problems with being able to focus. “The reflection is only 100 percent if you can create a focused beam with lenses that just are not available today. But a terrific 80 percent reflection should be possible even with today’s conventional lenses and laser beams.”Sandoghdar’s group has been considering future developments for this work, and Agio discusses some of the possibilities. “We are considering the use of optical antennas to overcome the limitations of focusing. We should be able to channel and collect light more efficiently, improving the coupling between a photon and a single molecule, very much in the same way the antenna in your cell phone receives and send calls.” He pauses before adding: “We’d have to make it very small, though, scaling everything down to optical frequencies is challenging.” Agio is optimistic. He points out that the group has already done some work along the lines of optical antennas, and that it, too, has been reported in Physical Review Letters. “We have already shown experimentally that noble metal nanoparticles are very efficient optical antennas for single molecules,” he says, referencing an article titled, “Enhancement of single molecule fluorescence using a gold nanoparticle as an optical nano-antenna.” “Now,” he continues, describing the next steps, “we are working on how to combine the focusing with the antenna to make all of this workable.”More Information: G.

New theory proposed to explain Pioneer probe gravitational anomaly

first_img( — Portuguese physicists might have finally solved the decades old mystery of why the Pioneer probes, launched in the early 70’s, haven’t been decelerating from the Sun’s gravitational pull at the rate expected; it seems it might be something as mundane as adding in the tiny forces that occur when minute traces of heat from the plutonium on board the probes bounce off their receiving dishes, creating a counterforce, which in turn, causes the craft to slow; if ever so slightly. Citation: New theory proposed to explain Pioneer probe gravitational anomaly (2011, April 27) retrieved 18 August 2019 from The Pioneer anomaly, as it’s come to be known, has had physicists scratching their heads ever since an astronomer by the name of John Anderson, working for NASA’s Jet Propulsion Laboratory, back in 1980, noticed a discrepancy between the slowdown rate projections for the craft and the rates they were actually experiencing, which led to the basic question, how could both probes be slowing down faster than the laws of physics projected? Possible explanations ranged from unknown mechanical issues with both craft, to dark matter pushing back, to possible flaws in the physics theories themselves.But now, Frederico Francisco of the Instituto de Plasmas e Fusao Nuclear, Lisbon Portugal and colleagues, as they describe in their paper published in arXiv, seem to have solved the problem using a simple old technology. Suspecting that heat was involved, they started with follow-up work by Anderson in 2002 and Slava Turyshev in 2006, also from NASA’s Jet Propulsion Laboratories, who both showed that heat released from the plutonium onboard the spacecraft could very well explain a slowdown. Unfortunately, both concluded that such heat emissions could not possibly account for the amount of slowdown seen. But this was because neither man thought to consider the impact of heat hitting the backside of the satellite dish (antennae) and then bouncing back. Francisco and his team used a computer modeling technique called Phong shading to show how the flow of heat as it was emitted from the main equipment compartment could emanate outwards, eventually bouncing off the back of the dish, resulting in just enough counterforce to explain the gravitational discrepancy.Case closed, as far as Francisco et al are concerned, but of course this being science, others will have to replicate the results before any sort of consensus can be found. © 2010 TPS Enables Study Of Mysterious Pioneer Anomaly More information: Modelling the reflective thermal contribution to the acceleration of the Pioneer spacecraft, arXiv:1103.5222v1 [] present an improved method to compute the radiative momentum transfer in the Pioneer 10 & 11 spacecraft that takes into account both diffusive and specular reflection.

Al Qaeda suspects porn film found to contain treasure trove of secret

first_img Hide files within files for better data security Citation: Al Qaeda suspect’s porn film found to contain treasure trove of secret documents (2012, May 4) retrieved 18 August 2019 from The files were hidden in the video file through a process called steganography or concealed writing. The term steganography includes methods used for centuries, such as invisible ink, but now also includes techniques such as concealing (often unencrypted) content inside a digital image, video or audio file. Steganography conceals data within “plain sight,” which makes it difficult to detect.Digital steganography can be done on audio files by manipulating the waveform to hide data, but such changes produce noise that is more obvious than changes visible to the eye. Data can be hidden in image files opened in a text editor simply by inserting text at the end of the file, but more sophisticated and effective methods use special software to manipulate individual bytes or pixels of the media file. For example, readily available software can be used to manipulate the properties of individual pixels within an image. The color of pixels is determined by vector values representing the intensity of each color (red, green and blue in RGB systems, for example), and these values can be manipulated to hide data.Other steganographic software tools convert bytes of data to be concealed into individual binary bits (0 and 1) that are then substituted for the least significant bits in the media file. The substitutions are spread throughout the media file following a sequence or algorithm, to make detection more difficult and distortion of the media file less noticeable. Another, even more sophisticated method is to manipulate the discrete cosine transform coefficients (DCTs) used to compress JPEG files to hide data into parts of an image. This method enables the hidden data to survive even if the image is later cropped, resized or compressed.The forensic task of revealing data hidden within files is complicated because the area is rapidly developing and becoming ever more sophisticated, but security programs are available that can help researchers detect manipulations within images and other digital files.The researchers from the German Federal Criminal Police (BKA), spent many weeks examining the hidden pornographic video found on suspected Al Qaeda member, the Austrian Maqsood Lodin, when he was arrested in Berlin after returning from Pakistan. The video, called “Kick Ass,” was stored in a password-protected folder and within the video they found a file called “Sexy Tanja.” Further analysis of this file eventually revealed that it contained more than 100 concealed unencrypted documents describing Al Qaeda plans and operations. A video file has ample room for concealing documents, and would be relatively easy to distribute. In Maqsood Lodin’s memory stick, the porn video contained hidden terrorist training manuals in pdf form in English, German and Arabic, along with numerous documents detailing planned future Al Qaeda attacks, and lessons learned from previous operations. Lodin is currently on trial in Berlin, and has pleaded not guilty to charges of terrorism. This document is subject to copyright.

Scientists uncover clues to ATP mystery and how cells work

first_img Researchers uncover secrets of internal cell fine-tuning Although many parts of the cellular movement process are well-understood, there is still some mystery in the details. One mystery in particular is that long polymer chains of actin (called F-actin) have been observed to use ATP at a rate that is more than 40,000 times faster than that of individual monomers of actin (called G-actin). This gigantic rate difference has been experimentally investigated for more than 25 years without a solution.Now in a new paper in the Journal of the American Chemical Society, researchers Martin McCullagh, Marissa G. Saunders, and Gregory A. Voth at The University of Chicago have used quantum mechanics/molecular mechanics (QM/MM) simulations of G- and F-actin, guided by coarse-grained modeling, to investigate how the structural differences of the two types of actin may contribute to the rate difference at which they use ATP, a process called ATP hydrolysis.”I think this work provides a fundamental molecular understanding of how actin filaments catalyze ATP hydrolysis, which in turn is critical to their behavior,” Voth told “ATP hydrolysis modulates many actin properties, which in turn is very important to the behavior of the cellular cytoskeleton. Some of these properties are relevant to, e.g., the binding of anti-cancer drugs in targeting cancer cells.”In ATP hydrolysis, actin filaments use ATP by breaking off one of its three phosphate atoms. The chemical energy stored in the phosphate bond is released and can be used for many purposes. Here, the energy is used to change the properties of the actin filaments, after which the polymer can be disassembled. This continuous growth and disassembly is what causes cells to move. Basically, what the rate difference mystery means is that somehow actin polymerization accelerates ATP hydrolysis. In other words, as the actin forms a filament, the faster it can use ATP. The effect is cyclical, so that the higher the rate of ATP hydrolysis, the higher the rate at which actin can be depolymerized. This activity leads to a remarkable phenomenon called actin “treadmilling,” which is essential to cellular movement. Journal information: Journal of the American Chemical Society Water molecules can rotate more freely in G-actin than in F-actin. The F-actin snapshot (a) has a three-water wire, and the G-actin snapshot (b) has a six-water wire.

DOI: 10.1021/ja507169f Artistic rendering of the actin structures and free energy surfaces calculated for ATP hydrolysis in G-actin and F-actin, computed using QM/MM simulations. Credit: McCullagh, et al. ©2014 American Chemical Society The new QM/MM simulations help explain the dramatic rate increase of ATP hydrolysis that occurs in F-actin compared to G-actin. The simulations show that certain key amino acids change position during polymerization, which promotes the rearrangement of nearby water molecules. The water molecules can rotate more freely, allowing them to easily align into shorter “water wires” that transport protons through the water very quickly—almost instantaneously, in fact. The resulting ease with which the protons can move corresponds to a lowering of the free energy barrier of that process. Since proton transport is a key step in ATP hydrolysis, overall less energy is required for F-actin to hydrolyze the ATP molecules.The simulations reveal a barrier height reduction that agrees well with the experimentally measured value, supporting the explanation that the favorable proton transport environment in F-actin plays an important role in the increased ATP hydrolysis rate. “There are many, many proteins that utilize ATP (or GTP) hydrolysis for modulate their behavior,” Voth said. “I think this work opens up the possibility to include that process more routinely in the computational study of proteins.” ( —Strong, thin fibers called microfilaments, or actin filaments, are present in the cytoplasm of almost every cell in the body. By growing and shrinking, actin filaments play a major role in cellular movement. Since these processes require large amounts of energy, actin filaments use a lot of ATP (adenosine triphosphate), a molecule that is often called the energy currency of the cell. © 2014 Phys.orglast_img read more

first_imgWhen a seemingly innocuous image of a woodpecker stashing away its acorn supply made the internet rounds, Twitter-users expressed revulsion. They weren’t reacting to the bird or the actual acorns, but to the set of holes in which the bird was storing its treasure. Clustered in an irregular pattern, the holes were triggering a condition called trypophobia. So why is this phobia so common? Scientists are still trying to answer this question, but many believe the aversion is evolutionarily adaptive. “We know that this condition pre-existed the internet — although the internet may have exacerbated it,” Arnold Wilkins, a psychologist at the University of Essex, told Live Science.  “You avoid things that are likely to harm you,” Wilkins explained. To someone with this phobia, an otherwise benign – and even downright gorgeous – image can spark fear and disgust. These individuals aren’t just afraid of any hole they see. Trypophobia is characterized by an aversion to clustered patterns of irregular holes or bumps. The term seems to have been coined by someone in an online forum in 2005, though scientists say the condition has likely been around for much longer. The phobia isn’t an official disorder, meaning it’s not listed in the “Diagnostic and Statistical Manual of Mental Disorders,” but up to 10% of people report experiencing symptoms, which include anxiety, nausea and a “skin-crawling” sensation, Wilkins said, after viewing certain images. “It can be quite debilitating,” he added. In the first ever scientific documentation of trypophobia published in Psychological Science, Wilkins compared trypophobia-triggering images with pictures of poisonous animals, like the blue-ringed octopus. He and his co-authors found a similar distribution of spots, bumps or holes, as well as a similar level of contrast in the images. The researchers concluded that the phobia could stem from an evolutionarily adaptive aversion to poisonous creatures. Read the whole story: Live Sciencelast_img read more

Expand your social network to enjoy healthier life

first_imgThe more social ties people have, the better their health is during adolescence and the golden years of their lives, says a new study.“Based on these findings, it should be as important to encourage adolescents and young adults to build broad social relationships and social skills for interacting with others as it is to eat healthy and be physically active,” said one of the researchers Kathleen Harris, professor at University of North Carolina at Chapel Hill, US. Also Read – ‘Playing Jojo was emotionally exhausting’The study builds on previous research that shows that aging adults live longer if they have more social connections. Specifically, the team found that the sheer size of a person’s social network was important for health in early and late adulthood. In adolescence, that is, social isolation increased risk of inflammation by the same amount as physical inactivity while social integration protected against abdominal obesity. In middle adulthood, it was not the number of social connections that mattered, but what those connections provided in terms of social support or strain, the study said. “The relationship between health and the degree to which people are integrated in large social networks is strongest at the beginning and at the end of life, and not so important in middle adulthood, when the quality, not the quantity, of social relationships matters,” Harris said. The study was published in the journal Proceedings of the National Academy of Sciences.last_img read more

first_imgKolkata: The Government Railway Police (GRP) on Wednesday filed an FIR over the foot over-bridge stampede that happened at Santragachi junction on Tuesday.The Railways also said that it will form a four-member special committee comprising the heads of various departments to investigate the incident. The members visited the accident site on Wednesday afternoon and also interacted with the locals and daily commuters to understand the daily scenario. Also Read – Rain batters Kolkata, cripples normal lifeThe committee consists of Principal Chief Commercial Manager P K Sahu, Principal Chief Engineer J N Laldas, Principal Chief Security Commissioner S C Parhi and Chief Safety Officer G K Dwivedy from South Eastern Railway. The committee will also look into the allegation regarding a change of platform of trains. According to sources, the Railways authority has denied allegations regarding the announcement on change of platforms from their end. A Railways official stated that nothing could be stated before the inquiry ends. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedDaily commuters alleged that Santragachi station is not equipped with sufficient infrastructure and despite that, the Railway authority has been using the station as a full-fledged junction. “Santragachi station needs at least two more foot over-bridges to cater daily commuters. A huge number of commuters use Santragachi station daily,” said a regular commuter. On Wednesday, the South Eastern Railway informed that the authority will bear the entire cost of treatment for the injured passengers. Railway doctors are attending the injured passengers since last Tuesday evening to provide all necessary support for the treatment that is being undertaken at the hospital. Meanwhile, late on Tuesday night, Indian Railways declared compensation of Rs 5 lakh each for the family members of the deceased. Persons with grievous injuries will be given Rs 1 lakh each and Rs 50,000 for those with minor injuries. On Tuesday evening, two persons were killed and 12 others injured after a stampede occurred at Santragachi station. Chief Minister Mamata Banerjee visited the accident spot at Santragachi and Howrah State General Hospital. She declared a compensation of Rs 5 lakh to families of the dead and Rs 1 lakh for each injured person before the Indian Railways announced their compensation. She also informed that the state government will do a separate probe into the matter. Locals informed that three trains came almost at the same time on platforms 1, 2 and 3 respectively. The Railway authority changed the platform number for the trains at the last moment. As no advance announcement was made, a large number of passengers tried to reach their respective platforms using the foot over-bridge to avail their trains which led to the rush, resulting in the stampede.last_img read more

The Education minister also instructed to make arrangements for commencing classes in the school from November 10 onwards. The school has remained closed for an indefinite period of time since the incident. The minister has appealed to the parents to co-operate with the management of the school as studies have been jeopardized due to the closure. It may be mentioned that on August 20, two students Tapas Burman and Rajesh Sarkar were killed in firing during a clash that broke out over teacher recruitment at Daribhit in Islampur. The school has remained close since the incident. The district inspector of schools in North Dinajpur Rabindranath Mondal was suspended after it was found that there was no need of an Urdu teacher neither there was any vacancy but the school was in the process of recruiting a teacher for Urdu which led to the unfortunate incident. The state government has handed over the investigation of the case to the Criminal Investigation Department (CID).last_img read more

Marking a year of GI tag Misti Hub celebrates Rosogolla Divas

first_imgKolkata: Rasogolla Divas was celebrated with great enthusiasm at Misti Hub in New Town to mark the first anniversary of International GI (Geographical Indication) tag by Bengal.The programme was organised by Housing Infrastructure Development Corporation (HIDCO). Noted scholar on Kolkata Haripada Bhowmick narrated the story on how Bengal got the international GI tag for Rosogolla setting aside Odisha’s claim. It was in 1868, one hundred and fifty years ago Nabin Chandra Das invented sponge Rosogolla. Kalidas Indra brought a sweet very close to Rosogolla that was discovered at Shantipur in Nadia district to Kolkata and set up a shop at Bagbazar. Nabindra Chandra joined his shop as a helper in 1860 and later started his own business in 1864. Also Read – Rain batters Kolkata, cripples normal lifePratap Rudradev King of Odisha became a disciple of Chaitanya Mahaprabhu. He added sweets made of Chana and offered it to Lord Jagannath as sweets made out of Chana were liked by Mahaprabhu. As Chana is a waste product of milk it was not offered to God. As King Pratap Rudradev introduced Chanabada, Odisha government claimed its GI right over Rosogolla as Chanabada is the ancestor of Rosogolla. However, following the intervention of Chief Minister Mamata Banerjee, Bengal bagged the international GI tag for Rosogolla. Rosogolla is famous world-wide. Over the years, modern varieties of Rosogolla like the baked Rosogolla and Orange Rosogolla have become quite famous. About 10 persons who have made new Rosogolla recipes were given certificates by HIDCO.

All state govt depts should surrender unutilised funds by Jan 31 Finance

first_imgKolkata: The state Finance department has recently issued a notification asking all state government departments to surrender funds that are lying unutilised by January 31. The move will enable the Finance department to re-allocate the surrendered amount to those departments which require the augmentation of funds for implementation of their development and welfare programmes.”The formal proposal for surrender of funds should be sent to the Finance Department through e-office and not by a letter or via e-mail. The administrative departments should ensure that the fund proposed to be surrendered is available in e-bantan (distribution) at the department level. If the funds are lying in the directorates/districts, the administrative departments are requested to first withdraw it to their level before sending the proposal to the Finance department. Further, no funds should be sub-allotted from the heads of account for which surrender proposal has been sent to the Finance department,” read the notification. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedIn a review meeting held two months back regarding the implementation of state development schemes, the administrative departments were requested to assess the requirement or utilisation of funds depending on the schemes being implemented and their progress during the next four months. They were then asked to surrender the funds that are likely to remain unutilised under the state development schemes. The notification undersigned by H K Dwivedi, Additional Chief Secretary of the Finance department, stated that the process of fund surrendering will be completed only when the department is able to withdraw the amounts electronically from the budget of the administrative department in the Integrated Financial Management System (IFMS) to its i-Budget system. It may be mentioned that financial performance of the departments in utilisation of funds would be assessed on the net funds available with them after factoring in the augmentation and surrender of funds.last_img read more

Sharenting may put childs safety at risk

first_imgSharenting – a parent’s habitual use of social media to share news and images about their children – puts the child’s online privacy and, potentially, safety at risk, warn researchers. The researchers found evidence that women’s feelings of vulnerability about being a mother are linked to their posting on social media. Those posts sometimes include their children’s personally identifiable information, such as names, birthdates, and photographs, showed the findings published online in the Journal of Public Policy and Marketing. The women who participated in the research articulated a variety of risk factors for vulnerability – a changing body, a changing view of self, new responsibilities associated with motherhood, demands of nursing, exhaustion, and issues such as postpartum depression or anxiety. The researchers suggest the need for enhanced governmental guidance to protect children’s online privacy from commercial entities.last_img read more

DNA Reveals the Origin of Stonehenge Builders

first_imgThe iconic site of the Stonehenge monument in Wiltshire, England, is shrouded in mysteries, including the details of its builders. New research has now revealed the British ancestors who constructed the monument were migrants who arrived on the island roughly around 4,000 BC. These early arrivals in Britain seem to have traveled from Anatolia, in modern-day Turkey, and would replace previous hunter-gatherer populations that lived on the island, the BBC reported on April 16th.The research draws conclusions from DNA comparisons from material collected from skeletal remains dated to the Neolithic age, and excavated from both around Britain and continental Europe. The findings were presented in the journal Nature Ecology & Evolution.Druids Worshiping at Stonehenge, England, in Ancient Times – engraved illustration (digitally enhanced) from The Popular Pictorial Bible, published in 1862Britain’s Neolithic tenants were one of two groups of migrants who separated after they began their journey from the Near East as early as 6000 BC. While one of these migration groups reached and developed early farming cultures across areas of Central Europe, the second group — the one which eventually settled in Britain — initially reached present-day Spain, before finally moving the north, the research suggests.AdChoices广告inRead invented by TeadsRelated Video: Pagans & Druids Welcome Winter Solstice“When the researchers analyzed the DNA of early British farmers, they found they most closely resembled Neolithic people from Iberia (modern Spain and Portugal). These Iberian farmers were descended from people who had journeyed across the Mediterranean,” writes the BBC.From Turkey to Iberia, and from Iberia to Britain, these early farmers would have mingled with hunter-gatherers they met on their way. Amid their great migration, they certainly also took the time to adapt their farming techniques, especially as they were progressing from warmer to colder realms.Stonehenge, closeupIn order to reach Britain, they would have needed to make passage by boat, most likely landing at either south-west England or Wales. But future research is needed to confirm this information. Before this wave of migrants, Europe was inhabited by small nomadic groups of people who were reliant on hunting, fishing, and foraging. The new arrivals not only introduced farming, but also other civilizational advancements.The smaller Stonehenge ‘bluestones’ were excavated from the Preseli hills in Pembrokeshire, Wales, almost 200 miles from the siteOne of the greatest proofs to this hypothesis can be found in Britain, where the Neolithic early farmers brought the knowledge of constructing megalithic monuments. It was the ancestors of these people that began the actual work of Stonehenge.Work on Stonehenge lasted for several centuries, with the first construction stage starting around 3000 BC. In it’s earliest form, Stonehenge was a simple circular enclosed earthwork, typical for henges of the era.The first standing stones were erected at Stonehenge more than 5,000 years agoTimber posts would have been added sometime around 2800 BC, just a few centuries before the Neolithic farmers were replaced by another wave of migrants: the Bell Beaker culture.For the purposes of the latest research, 47 Neolithic farmer skeletons were examined for their DNA, the majority of the samples dating from 6,000 to 4,500 years ago. Six of the skeletons were dated from 11,600 to 6,000 years ago, hence classified as Mesolithic hunter-gatherers.A full face reconstruction of the 10,000-year-old ‘Cheddar Man’, pictured at the National History Museum in London on February 6, 2018.

Excavated in 1903, Cheddar Man gained renewed fame after his dark-skinned, blue-eyed reconstruction was presented at the Natural History Museum in 2018.In contrast to the Mesolithic people, the Neolithic farmers would have had different body attributes, such as paler skin, brown eyes, and dark-brown or black hair, the genetic comparison pointed out.Mesolithic microlith artefacts found at Stevoort, 2008. Photo by Vaneiles CC BY-SA 3.0The arrival of the early Neolithic farmers in Britain affected the populations that already inhabited the island. They gradually began to disappear, failing to produce any strong ancestry lineage, except for one group in Scotland.“We don’t find any detectable evidence at all for the local British western hunter-gatherer ancestry in the Neolithic farmers after they arrive,” said one of the study co-authors, Dr. Tom Booth from London’s Natural History Museum, the BBC reports.“That doesn’t mean they don’t mix at all, it just means that maybe their population sizes were too small to have left any kind of genetic legacy,” he said.Stonehenge at sunsetFinally, the end of Britain’s early Neolithic farmers came around the year 2450 BC, as the Bell Beaker wave of migrants introduced another demographic change on the island. Which means, in a relatively short period of time, Britain experienced two significant genetic shifts.Read another story from us: Massive Stone-Cutting Tools Shed New Light into the Building of StonehengeOf course, DNA analysis cannot alone completely explain the processes of how these genetic changes unfolded. What’s clearer is that each population left its trace on the island. In the case of the Neolithic farmers’ lineage, one of those most prominent traces was building the landmark site of Stonehenge, as well as aiding the key evolutionary transition from hunter-gather to agrarian society.last_img read more

Video James Harrison plays volleyball with a medicine ball

first_imgWhen the NFL announced that it sought to interview players who were mentioned in the Al-Jazeera steroid report, James Harrison told them he’d only talk if Roger Goodell interviewed him at his house.Goodell might want to think twice if Harrison invites him to play volleyball, because he prefers using a medicine ball over a Mikasa. Harrison posted a video to his Instagram of him and some buddies tossing a medicine ball around a volleyball court for their workout.One lesson everyone can take away from the video is: Don’t ever mess with James Harrison. Even at 38, he’s still one of the baddest dudes in the NFL.last_img read more

Gottlieb Ben Simmons has a long way to go

first_imgBen Simmons has a long way to goColin has proclaimed Ben Simmons as the future face of the NBA, but he only managed one single point in the Sixers Game 2 loss to the Celtics. Simmons potential is unquestioned, but Doug thinks before he can become a true superstar he’ll have to prove he can shoot it consistently. He also needs to improve his free throw shooting, which makes him a late game liability.Simmons’ overall potential is tantalizing, but he has a long way to go before he can be discussed on the same level as the true superstars in the game.
