Signatures of selection inscribed on poplar genomes
In a study published ahead online Aug. 24, 2014 in Nature Genetics, a team of researchers from Oak Ridge National Laboratory, the Department of Energy Joint Genome Institute, and West Virginia University used a combination of genome-wide selection scans and analyses to understand the processes involved in shaping the genetic variation of natural poplar (Populus trichocarpa) populations.

Are you as old as what you eat? Researchers learn how to rejuvenate aging immune cells
Researchers from UCL have demonstrated how an interplay between nutrition, metabolism and immunity is involved in the process of aging.

Study: Cutting emissions pays for itself
Health care savings can greatly defray costs of carbon-reduction policies.

Driving brain rhythm makes mice more sensitive to touch
In a new study researchers show that they could make faint sensations more vivid by triggering a brain rhythm that appears to shift sensory attention.

Acrylamide exposure impairs blood-cerebrospinal fluid barrier function
Acrylamide exposure impairs blood-cerebrospinal fluid barrier function.

Stanford bioengineers close to brewing opioid painkillers without using opium from poppies
Stanford Bioengineer Christina Smolke is just a couple of steps away from perfecting a process that uses genetically engineering yeast cells to replicate the entire opioid production process, eliminating the need to grow poppies.

'Just right' plant growth may make river deltas resilient
Research by Indiana University geologists suggests that an intermediate amount of vegetation -- not too little and not too much -- is most effective at stabilizing freshwater river deltas.

'Haven't my neurons seen this before?'
The world grows increasingly more chaotic year after year, and our brains are constantly bombarded with images.

Neuroscience and big data: How to find simplicity in the brain
Scientists can now monitor and record the activity of hundreds of neurons concurrently in the brain, and ongoing technology developments promise to increase this number.

Train your heart to protect your mind
Exercising to improve our cardiovascular strength may protect us from cognitive impairment as we age, according to a new study by researchers at the University of Montreal and its affiliated Institut universitaire de geratrie de Montreal Research Centre.

Study suggests repurposing anti-depressant medication to target medulloblastoma
An international research team reports in Nature Medicine a novel molecular pathway that causes an aggressive form of medulloblastoma, and suggests repurposing an anti-depressant medication to target the new pathway may help combat one of the most common brain cancers in children.

Mimicking natural evolution with 'promiscuous reactions' to improve the diversity of drugs
A revolutionary new scientific method developed at the University of Leeds will improve the diversity of 'biologically active molecules', such as antibiotics and anti-cancer agents.

Does apolipoprotein E mimetic peptide reduce neuronal apoptosis induced by DBI?
Researchers found that apolipoprotein E-derived therapeutic peptide (0.6mg/kg and 1.2mg/kg) improved synaptic stability and improved learning and memory performance after diffuse brain injury.

Evolutionary history of honeybees revealed by genomics
In a study published in Nature Genetics, researchers from Uppsala University present the first global analysis of genome variation in honeybees.

Effect of repeated-pulse transcranial magnetic stimulation at the Guangming point on EEGs
In a recent study reported in Neural Regeneration Research, repeated-pulse transcranial magnetic stimulation was administered to healthy people at the left Guangming and a mock point, and calculated the sample entropy of electroencephalogram signals using nonlinear dynamics. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
