Watching the luminescent gene switch

21-Jun-2016

"Clock genes" turn on and off, or "Express", in rhythmic patterns throughout the body to regulate physiological conditions and behaviour. When and how these genes express, especially in tissues outside the brain, is still poorly understood. Until now, scientists have lacked sufficient means to ...

A new trick for controlling emission direction in microlasers

21-Jun-2016

Researchers at Washington University in St. Louis have found a way to give photons, or light packets, their marching orders. The researchers have capitalized on the largesse of an energy state in an optical field to make photons in their lasing system travel in a consistent mode, either clockwise ...

New imaging method may predict risk of post-treatment brain bleeding after stroke

21-Jun-2016

In a study of stroke patients, investigators confirmed through MRI brain scans that there was an association between the extent of disruption to the brain's protective blood-brain barrier and the severity of bleeding following invasive stroke therapy. The results of the National Institutes of ...

Innovative device allows 3-D imaging of the breast with less radiation

20-Jun-2016

Preliminary tests have demonstrated that a new device may enable existing breast cancer imagers to provide up to six times better contrast of tumors in the breast, while maintaining the same or better image quality and halving the radiation dose to patients. The advance is made possible by a new ...

Electric fields weaker in slow-healing diabetic wounds

20-Jun-2016

People with diabetes often suffer from wounds that are slow to heal and can lead to ulcers, gangrene and amputation. New research from an international group led by Min Zhao, professor of ophthalmology and of dermatology at the University of California, Davis, shows that, in animal models of ...

New X-ray method allows scientists to probe molecular explosions

17-Jun-2016

Summer blockbuster season is upon us, which means plenty of fast-paced films with lots of action. However, these aren't new releases from Hollywood studios; they're one type of new "movies" of atomic-level explosions that can give scientists new information about how X-rays interact with ...

Using espresso machines to do chemistry

17-Jun-2016

Many chemists are familiar with taking trips to the espresso machine while running late-night experiments, but until now these excursions were merely undertaken for the caffeine boost. A group recently reported however, that espresso machines can quickly and inexpensively perform some complex ...

Super-resolution microscopy reveals unprecedented detail of immune cells' surface

16-Jun-2016

When the body is fighting an invading pathogen, white blood cells--including T cells--must respond. Now, Salk Institute researchers have imaged how vital receptors on the surface of T cells bundle together when activated. This study, the first to visualize this process in lymph nodes, could help ...

Watching 'jumping genes' in action

Real-time observation of transposon activity in living cells

16-Jun-2016

"Jumping genes" are ubiquitous. Every domain of life hosts these sequences of DNA that can "jump" from one position to another along a chromosome; in fact, nearly half the human genome is made up of jumping genes. Depending on their specific excision and insertion points, jumping genes can ...

Botox's sweet tooth underlies its key neuron-targeting mechanism

16-Jun-2016

The Botox toxin has a sweet tooth, and it's this craving for sugars - glycans, to be exact - that underlies its extreme ability target neuron cells in the body ... while giving researchers an approach to neutralize it. A study co-led by Rongsheng Jin, professor of physiology & biophysics at the ...
