Small molecules can starve cancer cells
Researchers from BRIC at University of Copenhagen have found that a small molecule in our cells can block autophagy in cancer cells making them more sensitive for treatment.

Graphene's 'Big Mac' creates next generation of chips
Scientists at the University of Manchester have come one step closer to creating the next generation of computer chips using wonder material graphene.

Study shows how bookmarking genes pre-cell division hastens their subsequent reactivation
By observing and measuring the kinetics of activation of a single gene locus in a cell before it divides and comparing it with the same gene's reactivation in newly formed daughter cells, CSHL professor David L.

New membrane lipid measuring technique may help fight disease
University of Illinois at Chicago chemists led by Wonhwa Cho reports that they've developed a technique which successfully quantifies signaling lipids on live cell membranes in real time, opening up possible new routes for treating diseases.

If you don't snooze, do you lose?
An ongoing lack of sleep during adolescence could lead to more than dragging, foggy teens, a University of Wisconsin-Madison study suggests.

Professor Doug Hilton wins Milstein Award for cytokine research
Medical researcher and director of the Walter and Eliza Hall Institute, Professor Doug Hilton, has become the first Australian recipient of the Seymour & Vivian Milstein Award for Excellence in Interferon and Cytokine Research.

UK government claims that patient choice improves health care is based on flawed research, experts say
Research which claims to show that the introduction of patient choice in the NHS reduced deaths from heart attacks is flawed and misleading, according to a report published in The Lancet on Oct.

Star packs big gamma-ray jolt, researchers discover
In the center of the Crab Nebula, the Crab Pulsar, a spinning neutron star left over when a supernova exploded, is pulsing out gamma rays with energies never seen before -- above one hundred thousand million electron volts, according to an international scientific team that includes researchers from the University of Delaware.

Progress in quantum computing, qubit by qubit
Engineers and physicists at Harvard have managed to capture light in tiny diamond pillars embedded in silver, releasing a stream of single photons at a controllable rate.

Brain imaging reveals why we remain optimistic in the face of reality
Why, in the face of clear evidence to suggest to the contrary, do some people remain so optimistic about the future?

Health effects of financial crisis: Omens of a Greek tragedy
There are signs that health outcomes in Greece have worsened during the financial crisis, especially in vulnerable groups.

Genome-wide studies have identified new genes involved in susceptibility to melanoma
Identified genes are related to programmed cell death and DNA repair.

Scientists discover 3 new gene faults which could increase melanoma risk by 30 percent
An international team of researchers has discovered the first DNA faults linked to melanoma -- the deadliest skin cancer -- that are not related to hair, skin or eye color.

Over past decade antiretroviral therapy has tripled the proportion of adults in western Europe achieving undetectable levels of HIV after failing all 3 original drug classes
Over the past decade in western Europe there has been a dramatic improvement in the ability of antiretroviral therapy to keep HIV under control in adults with virological failure to drugs from all three of the original antiretroviral classes, and an accompanying decrease in the rates of AIDS, according to a study published online first in the Lancet Infectious Diseases.

NYU biologists use Sinatra-named fly to show how to see the blues -- and the greens
NYU biologists have identified a new mechanism for regulating color vision by studying a mutant fly named after Frank ('Ol Blue Eyes) Sinatra.

Smarter toxins help crops fight resistant pests
An international collaboration involving researchers at the UA and Universidad Nacional Autónoma de México has found that a small genetic manipulation restores the efficacy of crop-protecting toxins derived from bacteria against pest insects that have become resistant.

Novel technique uses RNA interference to block inflammation
Massachusetts General Hospital researchers -- along with collaborators from Massachusetts Institute of Technology and Alnylam Pharmaceuticals -- have found a way to block, in an animal model, the damaging inflammation that contributes to many disease conditions.
