COVID-19 frequently causes neurological injuries

Without directly invading the brain or nerves, the virus responsible for COVID-19 causes potentially damaging neurological injuries in about one in seven infected, a new study shows. These injuries range from temporary confusion due to low body-oxygen levels, to stroke and seizures in the most serious cases, say the study authors.

Modelling extreme magnetic fields and temperature variation on distant stars

New research is helping to explain one of the big questions that has perplexed astrophysicists for the past 30 years - what causes the changing brightness of distant stars called magnetars. Magnetars were formed from stellar explosions or supernovae and they have extremely strong magnetic fields, estimated to be around 100 million, million times greater than the magnetic field found on earth.

A new strategy for the synthesis of crystalline graphitic nanoribbons

New work from a team of scientists led by Drs. Kuo Li and Haiyan Zheng from the Center for High Pressure Science and Technology Advanced Research (HPSTAR) collaborated with Dr. Jing Ju from Peking University found pressure-induced polymerization of 1,4-diphenylbutadiyne produces crystalline graphitic nanoribbons. Their study provides a new strategy to synthesize crystalline bulk graphene...

UK's test and trace 'having marginal impact': which countries got it right?

Scientists’ verdict on £12bn system has refocused attention on what is working elsewhere in cutting Covid-19 transmission ratesCoronavirus – latest updatesSee all our coronavirus coverageThe newly released assessment by the UK government’s scientific advisers that the £12bn test and trace programme “is having a marginal impact” in reducing Covid-19 transmission has refocused attention...

Blue Origin’s suborbital spaceship tests NASA’s moon landing system in Texas

Blue Origin’s suborbital spaceship today conducted a robotic rehearsal for a future touchdown on the moon — and by all appearances, it stuck the landing. Testing most of the elements of NASA’s precision lunar landing system was the top item on the agenda for today’s mission, which represented the 13th uncrewed test flight of a New Shepard spacecraft for Amazon CEO Jeff Bezos’ space...

Imaging light waveforms in air plasma

An international team that includes physicists at LMU has developed a new method with which to characterize the ultrafast oscillation of the electrical fields associated with light.

What can mussel shells teach us about the circular economy?

In a circular economy, design is about more than just creating a sustainable product. In this system based on eliminating waste and minimizing the use of resources, the design process is aimed at preserving the value of products and materials and keeping them in the economic system for as long as possible. So how do you do that? Ph.D. candidate Marita Sauerwein came up with a novel material based...

Advocating for a shift from race-based to race-conscious medicine

"I am Italian-Chilean-American (Mapuche), Marie is Haitian-American, and Jenny is Taiwanese-American. We have all experienced racially-tailored care at some point in our lives. Our lived experience enhances the authority of our work," says Yale School of Medicine MD-Ph.D. student Jessica Cerdeña, MPhil.

What lies beneath a volcano?

The complex plumbing system beneath volcanoes has been revealed in the clearest detail ever, marking a "major step forward" in our understanding of how they are formed and behave.
