Astronomers make first detection of polarized radio waves in Gamma Ray Burst jets

Gamma Ray Bursts (GRBs) are the most energetic explosions in the universe, beaming out mighty jets which travel through space at over 99.9% the speed of light, as a star much more massive than our sun collapses at the end of its life to produce a black hole. Studying

Serotonin linked to somatic awareness

Patients with heightened somatic awareness often experience unexplained symptoms -- headaches, sore joints, nausea, constipation or itchy skin -- that cause emotional distress, and are twice as likely to develop chronic pain. The condition is associated with illnesses such as fibromyalgia, rheumatoid arthritis and temporomandibular disorders, and is thought to

Melting of Himalayan glaciers has doubled in recent years: Fast-paced warming is consistently affecting huge region, says new study

"This is the clearest picture yet of how fast Himalayan glaciers are melting over this time interval, and why," said lead author Joshua Maurer, a Ph.D.

Northern lights' 'social networking' reveals true scale of magnetic storms

The researchers, led by Professor Sandra Chapman from the University's Department of Physics, have for the first time characterised the observations from over 100 ground based magnetometers in terms of a time-varying directed network of connections. They monitored the development of geomagnetic substorms using the same mathematics used to study

Fresh look at mysterious Nasca lines in Peru: Using a taxonomic approach, scientists have re-identified the huge birds drawn on the desert plains of Peru as hermits or pelicans

The lines and geoglyphs of Nasca and Palpa are located some 400 kilometers south of Lima, Peru and form a World Heritage Site covering an area of about 450 square kilometers..

The brain consumes half of a child's energy -- and that could matter for weight gain: New paper proposes that variation in brain energy expenditure during childhood could be linked to obesity risk

we have no idea how much the brain's energy expenditure varies between kids. This is a huge hole in our understanding of energy expenditure.

Processed foods and effect on developing fetus' brain: Autism link?

Saleh Naser, Latifa Abdelli and UCF undergraduate research assistant Aseela Samsam have identified the molecular changes that happen when neural stem cells are exposed to high levels of an acid commonly found in processed foods.

Plate tectonics may have driven 'Cambrian Explosion'

A team of scientists have given a fresh insight into what may have driven the "Cambrian Explosion" -- a period of rapid expansion of different forms of animal life that occurred over 500 million years ago. While a number of theories have been put forward to explain this landmark period,

How information is like snacks, money, and drugs -- to your brain: Researchers demonstrate common neural code for information and money; both act on the brain's dopamine-producing reward system

A new study by researchers at UC Berkeley's Haas School of Business has found that information acts on the brain's dopamine-producing reward system in the same way as money or food.

New research shows an iceless Greenland may be in our future

"How Greenland will look in the future -- in a couple of hundred years or in 1,000 years -- whether there will be Greenland, or at least a Greenland similar to today, it's up to us"

Human migration in Oceania recreated through paper mulberry genetics: Humans carried the plant, used to make barkcloth, as they colonized new islands across Oceania

The colonization of the remote, long-uninhabited Pacific islands has fascinated early European explorers, current scientists and members of Pacific Island communities today.

Antarctic marine life recovery following the dinosaurs' extinction

A team led by British Antarctic Survey studied just under 3000 marine fossils collected from Antarctica to understand how life on the sea floor recovered after the Cretaceous-Paleogene (K-Pg) mass extinction 66 million years ago. They reveal it took one million years for the marine ecosystem to return to pre-extinction

First-ever successful mind-controlled robotic arm without brain implants

Being able to noninvasively control robotic devices using only thoughts will have broad applications, in particular benefiting the lives of paralyzed patients and those with movement disorders.

Animals' brain activity 'syncs' during social interactions

Animal models are really important for being able to study brain phenomena at levels that we can't normally access in humans," says Michael Yartsev of the Department of Bioengineering at the University of California, Berkeley, and senior author of one of the papers
