Fear of spiders became part of our DNA during evolution, say scientists
2015-04-06
Arachnophobia could be a product of human evolution, according to new research.Spiders presented such a great danger to humans during the early evolutionary stages that a fear of the species became part of our DNA.In Africa, early in human evolution, those with a keen ability to spot the creatures outlived their less wary counterparts.
Turning back time by controlling magnetic interactions
2015-04-06
In many materials, macroscopic magnetic properties emerge when microscopically small magnets align in a fixed pattern throughout the whole solid. In a publication in Nature Communications, Johan Mentink, Karsten Balzer and Martin Eckstein from the University of Hamburg at the Center for Free-Electron Laser Science (CFEL) and the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) have predicted that the interactions causing this alignment can be changed almost instantaneously and reversibly under the influence of a laser pulse.

Artificial Sweeteners May Change Our Gut Bacteria in Dangerous Ways
2015-04-03
Many of us, particularly those who prefer to eat our cake and look like we have not done so, have a love-hate relationship with artificial sweeteners. These seemingly magical molecules deliver a dulcet taste without its customary caloric punch. We guzzle enormous quantities of these chemicals, mostly in the form of aspartame, sucralose and saccharin, which are used to enliven the flavor of everything from Diet Coke to toothpaste. Yet there are worries. Many suspect that all this sweetness comes at some hidden cost to our health, although science has only pointed at vague links to problems.

Destroyed Mosul artefacts to be rebuilt in 3D
2015-03-29
It didn't take long for the scientific community to react. Two weeks after the sacking of the 300 year-old Mosul Museum by a group of ISIS extremists went viral on Youtube, researchers from the ITN-DCH, IAPP and 4D-CH-WORLD projects launched Project MOSUL to virtually restore damaged artefacts and make them accessible from virtual museums.
Kids who are adopted get a boost in IQ
2015-03-29
New research has found that children who are adopted have slightly higher IQs than siblings who remained with their biological parents. The study, published in PNAS, was designed to tease apart genetic and environmental influences on intelligence. The results suggest that the education level of the parents who raise the child can have an impact on IQ, but there is still a strong relationship between the intelligence of the child and his or her biological parents.
Playing music by musicians activates genes responsible for brain function and singing of songbirds
2015-03-29
Although music perception and practice are well preserved in human evolution, the biological determinants of music practice are largely unknown. According to a latest study, music performance by professional musicians enhanced the activity of genes involved in dopaminergic neurotransmission, motor behavior, learning and memory. Interestingly, several of those up-regulated genes were also known to be responsible for song production in songbirds, which suggests a potential evolutionary conservation in sound perception and production across species.

Scorch marks left by spacecraft on Mars soon fade
2015-03-29
We've been making a mess on Mars, but the Red Planet is kind enough to tidy up after us. A study of the scorch marks left by the Curiosity rover and Phoenix lander as they touched down on the surface of Mars has revealed that they fade over time and should take an average of around 2.6 years to disappear.
Quantum Record! 3,000 Atoms Entangled in Bizarre State
2015-03-29
Using a single particle of light, scientists have for the first time linked together thousands of atoms in a bizarre state known as quantum entanglement, where the behavior of the atoms would stay connected even if they were at opposite ends of the universe.This finding, the largest number of particles that have ever been mutually entangled in an experiment, could lead to more precise atomic clocks, potentially helping to improve GPS, researchers say.
Bats obey ‘traffic rules’ when trawling for food
2015-03-28
Foraging bats obey their own set of 'traffic rules', chasing, turning and avoiding collisions at high speed, new research from the University of Bristol, UK has found.Dr Marc Holderied of Bristol's School of Biological Sciences studied pairs of Daubenton's bats (Myotis daubentonii) foraging low over water for stranded insects at a site near the village of Barrow Gurney in Somerset, UK.
Giant pandas’ secret social life revealed
2015-03-28
Everyone needs friends. Even giant pandas. It turns out that they are more sociable than we thought, hanging out together for weeks at a time.We know very little about wild pandas because they are so rare and live in almost impenetrable forest. But in 2010 and 2011, Vanessa Hull of Michigan State University and her colleagues were given permission to attach GPS tracking collars to five pandas in the Wolong National Nature Reserve in China.
Critters found in Antarctic ice show how tenacious life is
2015-03-28
Deep below the ice, far from the playful penguins and other animals that bring tourists to Antarctica, is a cold and barren world that by all indications should be completely void of life.But recently, scientists researching melting ice watched a half-foot-long (15-centimeter) fish swim by. Not long after that, they saw shrimp-like creatures.

Straw-powered cars could be a thing of the future thanks to new research. A new study pinpoints five strains of yeast capable of turning agricultural by-products, such as straw, sawdust and corncobs, into bioethanol -- a well-known alcohol-based biofuel.
Mediterranean Diet is Healthy, Pollutes Less
2015-03-28
The Mediterranean diet, a menu traditionally eaten in Spain, leaves less of a carbon footprint than that of the U.S. or the United Kingdom, according to a recent study.The consequences of climate change range from species extinction to sea-level increases and the spread of diseases. For this reason, researchers have been struggling for years to alleviate its effects, even limiting the pollution caused by food consumption.Related: Fit middle-aged men 'at lower risk for some cancers'
Poisons, plants and Palaeolithic hunters
2015-03-28
Dozens of common plants are toxic. Archaeologists have long suspected that our Palaeolithic ancestors used plant poisons to make their hunting weapons more lethal.Now Dr Valentina Borgia has teamed up with a forensic chemist to develop a technique for detecting residues of deadly substances on archaeological objects.
Neolithic culture may have kept most men from mating
2015-03-28
Studying the varying genetic diversity of different population groups is one method for piecing together the migration history of our species. Many analyses find a bottleneck in non-African populations dating back to around 50,000 to 100,000 years ago. This coincides neatly with the current estimate of the first wave of anatomically modern humans out of Africa. When humans first migrated out of Africa, they created a genetic bottleneck. Because a minority of people migrated, they took a minority of total human genetic diversity with them to the new colonies in Europe and Oceania.
Did Mars once have a nitrogen cycle? Scientists find fixed nitrogen in Martian sediments
2015-03-27
Scientists have found fixed forms of nitrogen in Mars. This suggests that there may have been a nitrogen cycle sometime in Mars' past. The detection has been verified through analyses of samples taken at three different points on Mars. Analyses are made by the instrument SAM (Sample Analysis on Mars) on board the unmanned rover Curiosity located on Mars.
A new spin on Saturn’s peculiar rotation
2015-03-27
The precise measurement of Saturn's rotation has presented a great challenge to scientists, as different parts of this sweltering ball of hydrogen and helium rotate at different speeds whereas its rotation axis and magnetic pole are aligned. A new method leads to a new determination of Saturn's rotation period and offers insight into the internal structure of the planet, its weather patterns, and the way it formed.
Moon’s Iron Core May Reveal Solar System Secrets with X-Ray Scan
2015-03-27
Deep beneath the surface of the moon lies an iron heart that scientists are probing in a new study: By using X-rays to scan the kind of iron probably found in the moon's core, scientists may gain better estimates of the core's size and composition.Studying this unique kind of iron, and subjecting to incredible temperatures and pressures similar to those in the heart of a moon or planet, these findings could also help model the interior of small rocky planets such as Mars and Mercury, researchers added.

Nasa will use a robotic arm to grab a boulder and send it into orbit around the moon, giving it its own moon, allowing astronauts to study the rock as it flies around the Earth.The Asteroid Redirect Mission (ARM) will also allow Nasa to demonstrate many of the technologies that will carry humans to Mars.Alt: Nasa plans mission to land on asteroid and explore deep space
Dark matter is ghostly and non-interactive
2015-03-27
A new study of colliding galaxy clusters has found that dark matter doesn't even interact with itself.The findings reported in the journal Science, mean some existing dark matter models - which give the mysterious substance properties similar to normal matter - will need to be revised."We have concluded that dark matter is most probably not interacting, so it exists in its ghostly state without interacting," says the study's lead author Dr David Harvey of the École Polytechnique Fédérale de Lausanne in Switzerland.
A Team of Biohackers Has Figured Out How to Inject Your Eyeballs With Night Vision
2015-03-27
In "people becoming superhuman" news, a small independent research group has figured out how to give humans night vision, allowing them to see over 50 meters in the dark for a short time.Science for the Masses, a group of biohackers based a couple hours north of Los Angeles in Tehachapi, California, theorized they could enhance healthy eyesight enough that it would induce night vision. To do this, the group used a kind of chlorophyll analog called Chlorin e6 (or Ce6), which is found in some deep-sea fish and is used as an occasional method to treat night blindness.
Virtual noses keep real-world VR sickness at bay
2015-03-27
As the new wave of virtual reality headsets barrel ever closer to consumer reality, the effects of "simulator sickness" on a significant portion of the population remain a concern. A group of researchers at Purdue University say they've found an easy way to mitigate this effect by adding one bit of reality that most VR simulations leave out: a virtual nose sitting persistently at the corners of your vision.
We recognise words like we do faces
2015-03-27
Experienced readers recognise whole words in much the same way we recognise a face, according to scientists who have observed the changes in brain scans that occur as a new word is added to our 'visual dictionary'.The work might lead to better ways to teach reading to people with hearing difficulties or dyslexia, say the authors, from Georgetown University Medical Centre, Washington, D.C, USA, writing in the Journal of Neuroscience.

Richard III, the last English king to die in battle 530 years ago, was finally laid to rest on Thursday in a solemn ceremony in Leicester Cathedral, a few steps from the car park where his twisted skeleton was found in 2012."Today we recognize a king who lived through turbulent times and whose Christian faith sustained him in life and death," Queen Elizabeth II said in a message written for the service.Related: Richard III Reburial: Is England Honoring a Murderer?
BPA cuts fertility in fish 3 generations later
2015-03-26
The offspring of fish exposed to Bisphenol A (BPA) have decreased fertility and increased embryo mortality three generations later. A new study suggests that exposed humans and their children could be affected in the same way.BPA is a chemical that is used in a variety of consumer products, including water bottles, dental composites, and resins used to line metal food and beverage containers. Aquatic environments such as rivers and streams often become reservoirs for these endocrine-disrupting chemicals.
New Snakebite Antidote Borrows from Opossum’s Immunity
2015-03-26
Snakebite victims may one day have the humble opossum and its curious immunity to snake venom to thank for an antidote that can be made cheaply and administered in as large a dose as needed, without side effects.During an annual meeting and exposition being held this week by the American Chemical Society in Denver, a research team out of San Jose State University announced it had synthesized part of a serum protein from opossums that protected laboratory mice from the venom of both U.S. diamondback rattlesnakes and Russell's vipers from Pakistan.
