Liver protein crucial for pregnancy
A protein first shown to function in the liver plays a crucial role in pregnancy in mice and has a key role in the human menstrual cycle, according to researchers at the University of Montreal.

Different neuronal groups govern right-left alternation when walking
Scientists at Karolinska Institutet in Sweden have identified the neuronal circuits in the spinal cord of mice that control the ability to produce the alternating movements of the legs during walking.

Observing live gene expression in the body
Most of our physiological functions fluctuate throughout the day. They are coordinated by a central clock in the brain and by local oscillators, present in virtually every cell.

Is that bacteria dead yet?
Researchers at EPFL have built a matchbox-sized device that can test for the presence of bacteria in a couple of minutes, instead of up to several weeks.

Tobacco control policies stop people from smoking and save lives
Tobacco control measures put in place in 41 countries between 2007 and 2010 will prevent some 7.4 million premature deaths by 2050, according to a study published in the Bulletin of the World Health Organization.

New understanding of tiny RNA molecules could have far-ranging medical applications
A team led by scientists at The Scripps Research Institute has identified a family of tiny RNA molecules that work as powerful regulators of the immune response in mammals.

Cancer is a result of a default cellular 'safe mode,' physicist proposes
With death rates from cancer have remained largely unchanged over the past 60 years, a physicist is trying to shed more light on the disease with a very different theory of its origin that traces cancer back to the dawn of multicellularity more than a billion years ago.

Genomic atlas of gene switches in plants provides roadmap for crop research
A Canadian-led study will help scientists identify key genomic regions in canola and other food plants.

Diamond catalyst shows promise in breaching age-old barrier
In the world, there are a lot of small molecules people would like to get rid of, or at least convert to something useful, according to University of Wisconsin-Madison chemist Robert J.

The quantum secret to alcohol reactions in space
Chemists have discovered that an 'impossible' reaction at cold temperatures actually occurs with vigour, which could change our understanding of how alcohols are formed and destroyed in space.

DNDi and Cipla advance development of pediatric 4-in-1 ARVs to fulfill new WHO guidelines
The World Health Organization's new HIV treatment guidelines, released today at the 2013 International AIDS Society Conference, include new antiretroviral therapy recommendations for HIV-infected children, and will mean that more children will be on better treatments.

El Nino unusually active in the late 20th century
Reliable prediction of El Nino response to global warming is difficult, as El Nino varies naturally over decades and centuries.

Risk factors affect the incidence of childhood pneumonia in modern urban apartment?
Using coal or wood as cooking fuel in rural areas was considered a major cause of pneumonia.

Penn Medicine researchers discover link between fear and sound perception
Researchers from the Perelman School of Medicine at the University of Pennsylvania have discovered in an animal model how fear can increase or decrease the ability to discriminate among sounds depending on context, providing potential new insight into the distorted perceptions of victims of PTSD.
