Cosmic rays drive galaxy's winds

VLA observations revealed that cosmic rays can play an important role in driving winds that rob galaxies of the gas needed to form new stars. This mechanism may be an important factor in galactic evolution, particularly at earlier times in the history of the universe.

Tracking raindrops, one molecule at a time

New research refines our understanding of the chemical traces that act as the rain's fingerprint. The work is crucial for understanding the Earth's water cycle, especially as it undergoes rapid change due to global warming, deforestation and other environmental catastrophes.

Scientists pinpoint druggable target in aggressive breast cancer

Researchers have set their sights on a new therapeutic target for an aggressive form of breast cancer with limited treatment options. Through a comprehensive and cutting-edge genomic screening method known as CRISPR/CAS9 screening, scientists were able to identify a specific enzyme called UBA1 that revealed itself as an ideal therapeutic target. Using a novel UBA-inhibiting drug called TAK-243,...

Climate change is closing daily temperature gap, clouds could be the cause

New research has found that the difference between the daily high temperature and the daily low temperature -- known as the diurnal temperature range -- will continue to shrink in parts of the world as climate changes because of a projected increase in daytime cloud cover. The diurnal temperature range has a significant effect on growing seasons, crop yields, residential energy consumption and...

Migrating birds attracted by light pollution face higher toxic chemical exposure

The journeys of night-migrating birds are already fraught with danger. Light pollution adds yet another hazard beyond the increased risk of collisions with buildings or communication towers. According to a new study, birds attracted by the glow of artificial light at night are drawn into areas where they are also exposed to higher concentrations of airborne toxic chemicals.

The next wonder semiconductor

In a study that confirms its promise as the next-generation semiconductor material, researchers have directly visualized the photocarrier transport properties of cubic boron arsenide single crystals.

Greenbelts are effective at slowing urban sprawl

Researchers argue that greenbelts almost always work in curbing sprawl, particularly in larger cities. It looks at 60 cities in Europe, half of them with a greenbelt, half without, and uses open-source data to compare changes in and levels of urban sprawl between 2006 and 2015. 'We noticed decreases in urban sprawl in 27 of the 30 cities that had greenbelts, so we can say that overall, greenbelts...

Functional, nonepileptic seizures show structural abnormalities in brain scans, study shows

Functional seizures not caused by epilepsy are associated with structural changes in the brain that can be seen using MRI, a new study shows. Scientist have long understood the nonepileptic seizures as the body's response to mental stressors, such as anxiety and PTSD. Researchers say the findings bring potential for earlier diagnosis of functional seizures, which are often misdiagnosed as...

First quasiparticle Bose-Einstein condensate

Scientists have created a Bose-Einstein condensate out of excitons -- quasiparticles that combine electrons and positively charged 'holes' -- in a semiconductor. Quasiparticle Bose-Einstein condensates have for six decades been something of a holy grail of low-temperature physics.
