Evidence of diverse life forms dating back nearly a hundred thousand years has been found in subglacial lake sediments by a group of British scientists. The possibility that extreme life forms might exist in the cold and dark lakes hidden kilometres beneath the Antarctic ice sheet has fascinated scientists for decades.
New research shows that to prevent starvation at night, plants perform accurate arithmetic...

Irvine, Calif., March 25, 2013 — UC Irvine neurobiologists have found a novel molecular...
Building on earlier pioneering work by researchers at the University of California, San Diego, an international consortium of university researchers has produced the most comprehensive virtual reconstruction of human metabolism to date. Scientists could use the model, known as Recon 2, to identify causes of and new treatments for diseases like cancer, diabetes and even psychiatric and neurodegenerative disorders.
Donald Rowley, a pioneer in discovering how the immune system functions and the inventor of the gel electrode, a crucial tool that monitors cardiac activity, died at his home February 24, 2013,after a long battle with congestive heart failure. He was 90 years old.
Bacteria are common sources of infection, but these microorganisms can themselves be infected by even smaller agents: viruses. A new analysis of the interactions between bacteria and viruses has revealed patterns that could help scientists working to understand which viruses infect which bacteria in the microbial world
Self-conscious about your age? Be careful where you spit. Geneticists now can use saliva to reveal how old you are. The findings offer a myriad of potential applications. A newly patented test based on the research, for example, could offer crime-scene investigators a new forensic tool for pinpointing a suspect's age
A yet unidentified component of coffee interacts with the beverage’s caffeine, which could be a surprising reason why daily coffee intake protects against Alzheimer’s disease. A new Alzheimer’s mouse study found that this interaction boosts blood levels of a critical growth factor that seems to fight off the Alzheimer’s disease process
For migratory birds and sea turtles, the ability to sense the Earth’s magnetic field is crucial to navigating the long-distance voyages these animals undertake during migration. Humans, however, are widely assumed not to have an innate magnetic sense. But new research shows that a protein expressed in the human retina can sense magnetic fields when implanted into Drosophila
The Arabian Oryx, a species of antelope found only on the Arabian Peninsula. It is believed the last wild individual was shot in 1972. This year the oryx has finally qualified for a move from the Endangered category to Vulnerable the first time that a species that was once Extinct in the Wild has improved by three categories
There is a a higher DNA mutation rate in mammalian males than in mammalian females, a phenomenon called male mutation bias. A new study shows that generation time is the main determinant of this phenomenon
Much like walking or swimming, to make sounds, vertebrate (animals with a backbone) brains must use timing signals to coordinate carefully the right muscles. Researchers have now identified regions of a fish brain that reveal the basic circuitry for how all vertebrates, including humans, generate sound used for social communication
A team of researchers have discovered that, on average, thirty mutations are transmitted from each parent to their child, revising previous estimations and revolutionizing the timescale we use to calculate the number of generations separating us from other species
Scientists have confirmed that chytridiomycosis, a rapidly spreading amphibian disease, has reached a site near Panama’s Darien region. This was the last area in the entire mountainous neotropics to be free of the disease
In the 1960s and '70s a marine biologist at California's Scripps Institution of Oceanography (SIO), set out on field expeditions to remote places to study the fish of the Pacific Ocean. But due primarily to a lack of space at SIO, much of the treasure trove remained unsorted until now
Deadly bacteria may be evolving antibiotic resistance by mimicking human proteins, according to a new study. This process of “molecular mimicry” may help explain why bacterial human pathogens, many of which were at one time easily treatable with antibiotics, have re-emerged in recent years as highly infectious public health threats
Inside the human body, an amazing amount of communication occurs constantly. And for biologists, the fundamental question remains as to how these processes occur within the complex environment of tissues and organs
LifeScope 2.0 Genomic Analysis Software is a bioinformatics system for analyzing data from genomic sequencing instruments to study human disease such as cancer. The product features secure project management, pushbutton workflows and an intuitive user interface
Seeing ultraviolet light allows reindeer to take in live-saving information in conditions where normal mammalian vision would make them vulnerable to starvation, predators and territorial conflict. It also raises the question of how reindeer protect their eyes from being damaged by UV
The size and shape of the human cerebral cortex, an evolutionary marvel responsible for everything from Shakespeare's poetry to the atomic bomb, are largely influenced by mutations in a single gene, according to a team of researchers
John R. Joyce, Ph.D. The Crimson Project is about the development of an application, called Crimson, designed to address the always critical shortage of samples in clinical research
Superantigens, the toxins produced by staphylococcus bacteria, are more complex than previously believed, reveals a team of researchers. Their discovery shows that the body's immune system can cause more illnesses than realized
Mass Frontier 7.0 is small molecule structural elucidation software. The software simplifies the management, evaluation and interpretation of mass spectral data and can be used for metabolism, metabolomics, forensics, natural products, impurities and degradants research
This tool is the first search engine specialized in linking biomedical articles to nucleic acid sequences. It is an online repository created to link documents archived at PubMed Central with the nucleic acid sequences that they contain
With the help of a new method, neuroscientists have now discovered that neurons systematically recycle the protein components necessary for transmitter release. In this way they guarantee the reliability of signal transmission in the brain
In a finding that upends decades of scientific theory on reptile reproduction, researchers have discovered that female boa constrictors can have babies without mating. More strikingly, the finding shows that the babies produced from this asexual reproduction have attributes previously believed to be impossible
Researchers have reached an early, but important, milestone in the quest to grow replacement livers in the lab. They are the first to use human liver cells to successfully engineer miniature livers that function – at least in a laboratory setting – like human livers
Few fish are famed for their parenting skills. Most species leave their freshly hatched fry to fend for themselves, but not discus fish. A research explains that discus fish young feed on the mucus that their parents secrete over their bodies until they are big enough to forage
