Four new species of Ctenomys, a genus of gopher-like mammals found throughout much of South America, have been identified by researchers. The burrowing rodents are commonly called tuco-tucos. The burrowing rodents range from 7 to 12 inches long and weigh less than a pound. Show More Summary
A group of cells in the brain has been identified by researchers who say that it plays an important role in the abnormal neuron development in Down syndrome. After developing a new model for studying the syndrome using patient-derived...Show More Summary
Twisting a screwdriver, removing a bottle cap, and peeling a banana are just a few simple tasks that are tricky to pull off single-handedly. Now a new wrist-mounted robot can provide a helping hand -- or rather, fingers. Researchers have developed a robot that enhances the grasping motion of the human hand.
Genetic studies have given us detailed information about the evolutionary relationships embodied in the Tree of Life, while newly digitized museum collections contain a wealth of information about species distribution. To date, however, these big data collections have not been applied to conservation efforts. Show More Summary
The identification of the genes and proteins involved in a biological process, as well as the way they interact, are essential for the understanding of that process. However, often little is known about the dimensions of molecular biological structures. Show More Summary
The mystery behind the movements of flocking starlings could be explained by the areas of light and dark created as they fly, new research suggests. The research found that flocking starlings aim to maintain an optimum density at which they can gather data on their surroundings. Show More Summary
Over a 150 years since it was first described by Darwin, scientists are finally uncovering the secrets behind the super strength of barnacle glue. Still far better than anything we have been able to develop synthetically, barnacle glue -- or cement -- sticks to any surface, under any conditions. Show More Summary
Our immune system contains CD8+ T cells which protect us from various diseases such as cancer and viruses. Some of them are specifically tasked with killing cells infected with the HIV virus – and researchers have for the first time identified a key explanation for why these cells are unsuccessful in their task.

Oil produced from biomass - such as wood chips or plant residues - seldom has the same quality and energy content as ‘classical’ crude oil. A new, simple catalyst improves the quality of this oil before it is even transported to the refinery.
The spreading of a cancerous tumor from one part of the body to another may occur through pure chance instead of key genetic mutations, a new study has shown. Physicists have used a statistical model to show that the formation of a new...Show More Summary
UK legislation that targets 'dangerous dogs' has not been shown to reduce dog bites and policies should be based on evidence and risk assessment, suggests a new article. Risk assessment for human violence has proved to be accurate and...Show More Summary
HIV patients with a higher level of a particular biomarker, or a measurable indicator found in the blood, may respond more favorably to an experimental immune activating vaccine, a study suggests. Experts believe the findings might lead to a more customized vaccine for certain patients, which potentially might permit them to come off antiretrovirals, drugs used to treat HIV.
A significant breakthrough has been made that may benefit patients with bowel cancer. Researchers have discovered how two genes cause bowel cancer cells to become resistant to treatments used against the disease. The activity of theShow More Summary
Researchers have demonstrated that an array of novel gold, pillar-bowtie nanoantennas can be used like traditional photographic film to record light for distances that are much smaller than the wavelength of light. A standard optical microscope acts as a 'nanocamera' whereas the pillar-bowtie nanoantennas are the analogous film.
After studying 137 varieties of cheese collected in 10 different countries, researchers have been able to identify three general types of microbial communities that live on cheese, opening the door to using each as a 'model' community...Show More Summary
Vision loss is associated with a higher likelihood of not working, researchers report. Also, people who do not work have poorer physical and mental health, are less socially integrated and have lower self-confidence, they say.
Women sexually abused in childhood may show signs of atherosclerosis, an early marker of cardiovascular disease in midlife. Psychosocial factors are important to the development of cardiovascular disease, the leading cause of death among women in the United States. Show More Summary
Omega-3 fish oil might help protect against alcohol-related neurodamage and the risk of eventual dementia, according to a study. Many human studies have shown that long-term alcohol abuse causes brain damage and increases the risk of dementia. Show More Summary
It's normal for people to experience trouble sleeping after a divorce, but if sleep problems last too long, they can lead to potentially harmful increases in blood pressure, a new study finds. The research suggests that poor sleep quality might be one of the reasons divorce is linked to negative health effects.
Not unlike looking for the proverbial needle in a haystack, a team of researchers has found a gene that could be key to the development of stem cells -- cells that can potentially save millions of lives by morphing into practically any cell in the body. Show More Summary
