Unknown Mathematician Proves Surprising Property of Prime Numbers
An unknown mathematician, Yitang Zhang, has revolutionized his field and helped move forward a 2,000-year-old conjecture about prime numbers. His counterintuitive findings show that special pairs of primes, called twin primes, can never be more than 70 million places away...
New archaeological 'high definition' sourcing sharpens understanding of the past
A new method of sourcing the origins of artefacts in high definition is set to improve our understanding of the past. Dr Ellery Frahm at the University of Sheffield developed the new technology to better study Mesopotamian obsidian tools unearthed in Syria, where cultural heritage is threatened by the ongoing conflict. read more
Why do so many people hate cyclists?
We live in a world where a young woman claims, in a tweet, to have knocked a cyclist into the ditch then boasts about doing a runner. The primordially stupid 'EmmaWay20' justifies her actions by pointing out that the cyclist, Toby Hockley, 'doesn't pay road tax'. Ms Way, if that...
Insight into the dazzling impact of insulin in cells

USF researchers find far-reaching, microvascular damage in uninjured side of brain after stroke
Tampa, FL (May 20, 2013) -- While the effects of acute stroke have been widely studied, brain damage during the subacute phase of stroke has been a neglected area of research. Now, a new study by the University of South Florida reports...Show More Summary
Imaging technique shows premature birth interrupts vital brain development processes leading to reduced cognitive abilities in i
This video shows the development of the frontal and temporal regions of the cerebral cortex in preterm infants during the last three months before the normal time of birth, turning from red to blue as it matures. The primary motor and...Show More Summary
Ants and carnivorous plants conspire for mutualistic feeding
An insect-eating pitcher plant teams up with ants to prevent mosquito larvae from stealing its nutrients, according to research published May 22 in the open access journal PLOS ONE by Mathias Scharmann and colleagues from the University of Cambridge and the University Brunei Darussalam. read more
Captive-bred wallabies may carry antibiotic resistant bacteria into wild populations
Endangered brush-tail rock wallabies raised in captive breeding programs carry antibiotic resistance genes in their gut bacteria and may be able to transmit these genes into wild populations, according to research published May 22 in the open access journal PLOS ONE by Michelle Power and colleagues from Macquarie University in New South Wales, Australia. read more

What people take from nature – water, food, timber, inspiration, relaxation – are so abundant, it seems self-evident. Until you try to quantitatively understand how and to what extent they contribute to humans. In today's world, where...Show More Summary
Scientists develop worm EEG to test the effects of drugs
Scientists from the University of Southampton have developed a device which records the brain activity of worms to help test the effects of drugs. NeuroChip is a microfluidic electrophysiological device, which can trap the microscopic worm Caenorhadbitis elegans and record the activity of discrete neural circuits in its 'brain' - a worm equivalent of the EEG. read more
NLST: CT detects twice as many lung cancers as X-ray at initial screening exam
National Lung Screening Trial (NLST) investigators also conclude that the 20 percent reduction in lung cancer mortality with low-dose computed tomography (LDCT) versus chest X-ray (CXR) screening previously reported in the NLST primary paper is achievable at experienced screening centers in the United States. read more
NASA's SDO observes mid-level solar flare
The sun emitted a mid-level solar flare on the morning of May 22, 2013. The flare peaked at 9:38 a.m. EDT and was classified as an M7. M-class flares are the weakest flares that can still cause some space weather effects near Earth. In the past, they have caused brief radio blackouts at the poles. read more
'Boys will be boys' in US, but not in Asia
