Structural blueprint for RNA therapeutics reveals why some siRNA molecules work better tha

RNA interference is a natural mechanism for living cells to control whether specific genes are being used. Crowned with the 2006 Nobel Prize in Physiology or Medicine, the discovery of RNA interference has since been harnessed by scientists to create a powerful and growing class

New calculator reveals whether you should really worry about statin side effects

Scientists at the University of Oxford have created a calculator that predicts a person's individual risk of serious muscle disorders from statin medications. Their analysis found that more than 98% of people who qualify for statins are at low risk for these rare complications, d

Scientists say creatine may help fight depression

Creatine is best known as a muscle-building supplement, but scientists are now investigating whether it could also help treat depression by boosting the brain's energy supply. A new review examined five randomized clinical trials involving 238 participants and found mixed results

New bioelectronic microdevices enable remote cell stimulation using ultrasound

The Universitat Autònoma de Barcelona (UAB) and the Institute of Microelectronics of Barcelona (IMB-CNM-CSIC) have developed a new generation of wireless piezoelectric microdevices capable of electrically stimulating living cells at an individual level. The study, recently publis

Brown leaves before fall could signal lasting heat damage, researchers warn

Due to increasing heat and drought, forests are turning brown more often before autumn, when leaf senescence normally occurs. It is often unclear whether the trees are actively shedding foliage to avoid a breakdown in water transport or whether browning leaves are a consequence o

Paleontological study shows climate change makes marine animals shrink

Whether mussels, crustaceans or fish, marine animals have been responding to environmental crises with a reduction in body size for hundreds of millions of years. A new study by Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), in conjunction with the Universities of Warsa

Mammals use the same underlying system—preserved through evolution—to process smells

Picture a mouse taking rapid, staccato sniffs of a crumb it's found while foraging for food. Now compare that with a human leaning in for a single, deep inhale to gauge whether a cantaloupe is ripe. New research from Northwestern University has found that, like humans, mice also

Entrepreneurs more likely to be based in left wing areas

Research from the University of St. Andrews is challenging conventional assumptions about the relationship between politics and entrepreneurship. The study explored whether the political environment in which people live influences their likelihood of starting a business, and its

Health risk fears for storks in Europe over ‘junk food’ from landfill

Rubbish dumps can expose birds to contaminants, raising questions over whether landfill foraging helps or harmsStorks are gaining weight from a diet of literal junk, according to research that suggests the previously disappearing birds face potential health risks as a result of i

Could geoengineering work to tamp down super El Niños?

With an anticipated "super" El Niño looming, a new study led by UC San Diego's Scripps Institution of Oceanography considers whether society could use a weather-altering technique as a tool to mitigate the floods, extreme heat and other events that El Niño would bring. The findin

New CRISPR method makes it possible to control protein production in cells

The speed at which a cell produces proteins is a decisive factor in determining whether it divides, specializes or retains its stem cell properties. A team of researchers led by Professor Stefan H. Stricker, professor of epigenetic engineering at LMU's Biomedical Center and resea
