New Species of Tyrannosaur Discovered in Southwestern U.S.
A new species of tyrannosaur has been discovered in the Bisti/De-na-zin Wilderness of New Mexico. Bistahieversor was different from other tyrannosauroids in having an extra opening above its eye, a...
'Squeaker' catfish communicate across generations
It has been thought that young fish, lacking well-developed hearing organs, could not perceive the sounds made by their larger, older relatives. Now, researchers have used a combined fish tank...
Study recommends better handling of milk in restaurants
One-third of samples of milk and dairy products analysed in various restaurants exceed the microbe contamination limits set by the European Union, according to a study carried out by researchers...
Cancer researchers perform complete genomic sequencing of brain cancer cell line
Researchers have performed the first complete genomic sequencing of a brain cancer cell line, a discovery that may lead to personalized treatments based on the unique biological signature of an...
Mad-cow proteins created in the lab
Scientists have firmed up the evidence that misshapen protein are responsible for brain-wasting diseases by showing how these infectious prions are created.
ARS genetic analysis helps spot sugarcane rusts
Agricultural Research Service (ARS) scientists have analyzed rust fungi from more than 160 sugarcane samples from 25 countries to provide a valuable resource for plant breeders and pathologists who are...
Sex-free worms survive by drying up, blowing away
Tiny worm-like creatures that have no males and reproduce by cloning can escape disease by drying up and floating away on the breeze, researchers have found.
New insights into breast-feeding hormone
A mechanism for regulating the hormone prolactin has newly been revealed by scientists at Karolinska Institutet. The results are to be published in the scientific journal Neuron, and may be...
Developmental delay may explain behaviour of easygoing ape species
New research suggests that evolutionary changes in cognitive development underlie the extensive social and behavioural differences that exist between two closely related species of great apes. The study, published online...
Uncorrelated activity in the brain
Interconnected networks of neurones process information and give rise to perception by communicating with one another via small electrical impulses known as action potentials. In the past, scientists believed that...
Researchers decode transcriptome for grey mullet
The Cell Biology in Environmental Toxicology research team at the Department of Zoology and Animal Cell Biology at the University of the Basque Country (UPV/EHU) has decoded the transcriptome for...
Researchers find new way to study how enzymes repair DNA damage
Researchers at Ohio State University have found a new way to study how enzymes move as they repair DNA sun damage - and that discovery could one day lead to...
Seabirds' movement patterns tied to what fishermen toss away
Humans and human activities have clearly altered the Earth's landscape and oceans in countless ways, often to the detriment of other plants and animals. But a new report published online...
Washington panda cub to be shipped via FedEx to China
US-born panda cub Tai Shan will next week leave the National Zoo in Washington and head in grand style for a new life in China -- on board a Federal...
How to whip up a frothy frog nest
Scientists reveal how frogs perform the architectural feat of building floating foam "meringue" nests.
Frog that changes colour revealed
A new species of frog found in Papua New Guinea undergoes a dramatic change in colour as it grows older, report scientists.
Proteins' dynamic motion important in body's immune response
New research reveals the importance of dynamic motion by proteins involved in the body's immune response.
Hospital puts sea turtles with tumors on fast track
Forty scientists and veterinarians take part in removal of noncancerous growths from reptiles at a Florida nature center. Tumors are turning up on the turtles worldwide, but their cause is...
In sync: Squid, glowing companions march in genetic harmony
Most humans are blissfully unaware that we owe our healthful existence to trillions of microbes that make their home in the nooks and crannies of the human body, primarily the...

Virus-like particle vaccine protects monkeys from chikungunya virus
An experimental vaccine developed using non-infectious virus-like particles (VLP) has protected macaques and mice against chikungunya virus, a mosquito-borne pathogen that has infected millions of...
Freeloading Flap: Mediterranean Seabirds That Scrounge Off Fishing Boats Have a Smaller Foraging Range
Where there are fishery boats docking after a day's catch, there are usually seabirds hovering in hopes of lifting scraps. Discards from fisheries supplement the diets of these...
Neurons may function more solo than thought
Surprising observations of neuron firing patterns raise new questions about how the brain works
Are new genes always better?
Re-vegetation seems like a beneficial strategy for conserving and restoring damaged ecosystems, and using a variety of species can help increase biodiversity in these systems. But what are the...
"Sex Puppeteers" Force Sex Change, Virgin Birth in Bugs via Genes
Fast-spreading parasites force sex changes on victims, induce virgin births, and turn animals into "gross monsters"—all via genetic sabotage, a new study finds.
