A forest fire caused a radiation spike in the Chernobyl region, but that elevated radiation has not reached nearby, populated areas.

The advice on widespread face mask use to protect against covid-19 varies wildly, but there is some evidence that they stop sick people spreading the virus

The transport sector has been impacted as much as any by the coronavirus. This isn't a normal period of disruption, which is usually caused by failures in supply such as road accidents or industrial action. In this case ...

A multidisciplinary team of researchers at the University of Illinois at Urbana-Champaign has developed tiny sensors that measure oxygen transport in bovine lung tissue. The study -- which establishes a new framework for...

Digital cameras as well as many other electronic devices need light-sensitive sensors. In order to cater to the increasing demand for optoelectronic components of this kind, industry is searching for new semiconductor ma...

Physicists at ETH Zurich have developed the first high-repetition-rate laser source that produces coherent soft X-rays spanning the entire "water window." That technological breakthrough could enable a broad range of stu...

Engineers have created a laser treatment method that could potentially turn any metal surface into a rapid bacteria killer -- just by giving the metal's surface a different texture.

A new article calls attention to the risk posed by overreliance on COVID-19 testing to make clinical and public health decisions. The sensitivity of reverse transcriptase-polymerase chain reaction (RT-PCR) testing and ov...

Much remains unknown about COVID-19, but many studies already have indicated that people with cardiovascular disease are at greater risk of COVID-19. There also have been reports of ST-segment elevation (STE), a signal o...

Every moment of the day we are surrounded by smells. Odors can bring back memories, or quickly warn us that food has gone bad. But how does our brain identify so many different odors? And how easily can we untangle the i...

Researchers have discovered six new coronaviruses in bats in Myanmar -- the first time these viruses have been detected anywhere in the world. Future studies will evaluate the potential for transmission across species to...

What does it actually look like deep inside our ears? This has been very difficult to study as the inner ear is protected by the hardest bone in the body. But with the help of synchrotron X-rays, it is now possible to de...

The antimicrobial properties of silver have been known for centuries. Now scientists are seeking to better understand how the noble metal kills bacteria to help combat antiobiotic-resistant 'superbugs.'

A novel 'learning while doing' clinical trial approach called REMAP helps doctors find the optimal trade-off between quickly adopting new therapies during a pandemic, such as the anti-malarial drug hydroxychloroquine, an...

Researchers created technology that uses optical imaging to better help surgeons map out tumors in the body and help them understand how certain diseases affect activity in the brain.

Scientists report that the combined effects of rare, damaging mutations present at birth have a negative impact on healthspan and longevity.

It's time to encourage people to wear face masks as a precautionary measure on the grounds that we have little to lose and potentially something to gain, say experts in The BMJ today.

Researcher have found a new sublineage of enterovirus A71 (EV-A71) C4 subgenotype with two possible recombinant strains during the 2015-16 outbreak of hand-foot-and-mouth disease in Hanoi, northern Vietnam. Further, they...

Researchers showed that a protein named FOXO1 plays a critical role in heart damage resulting from treatment with anthracycline chemotherapy drugs. Using a rodent model, they also demonstrated that suppressing FOXO1 thro...

A new study reveals that tumors lacking a protein called BAP1 have an ineffective immune reaction against cancer, thus rendering immunotherapies ineffectual, particularly in uveal melanomas (UM). The researchers also dis...

MW189 blocks abnormal inflammation in the brain that is known to contribute to injury- and disease-induced neurologic impairments in a number of acute and chronic brain disorders. This study examined MW189 in healthy adu...

The research team discovered a new role for MAP2 in the synaptic potentiation process and expects to provide key insights into synaptic dysfunction in brain diseases.
