Ventilation matters: Engineering airflow to avoid spreading COVID-19

As we approach two full years of the COVID-19 pandemic, we now know it spreads primarily through airborne transmission. The virus rides inside tiny microscopic droplets or aerosol ejected from our mouths when we speak, shout, sing, cough, or sneeze. It then floats within the air, where it can be inhaled by and transmitted.

Ending Disease review – a powerful case for the miracle cure

In focusing on the stories of recovery this documentary, following patients participating in stem cell research trials in the US, allows the optimism to outshine the controversyHere is a film that tugs at the heartstrings as it painstakingly covers the lives of 10 patients participating in stem cell research trials in the US. From a quadriplegic high-school basketball star to a mother with...

New technique provides detailed information on nuclear material

Whether soil contaminated with nuclear material or archaeological finds: Analyzing isotopes can help determining the age and origin of a sample very accurately. Researchers from Leibniz University Hannover (LUH) and Johannes Gutenberg University Mainz (JGU) have now developed a new technique suitable for obtaining information on the origin of microparticles by analyzing isotope distributions. The...

80% of world economy now aiming for net zero—but not all pledges are equal

More than 80 percent of global GDP—and 77 percent of global greenhouse gases—are now covered by a national net zero target, up from 68 percent and 61 percent last year, according to a new tracker co-led by Oxford Net Zero. But that number shrinks to 10 percent of global GDP and 5 percent of global emissions, if only strong commitments and clear plans are included.

Heart rate synchronization and palm sweat found to be signs of attraction

A small team of researchers from Leiden University and one with the University of Birmingham has found that when two people are attracted to one another, their heart rates tend to synchronize and their palms sweat together. In their paper published in the journal Nature Human Behavior, the group describes experiments they conducted with volunteers in "dating cabins."

'Perfect for some but disastrous for others': Patients and clinicians express concerns over phone and video consultations

A study of rheumatology patients and clinicians has found that while the majority found phone or video consultations more convenient than face-to-face consultations, they viewed so-called telemedicine as less diagnostically accurate than in-person consultations and as having the potential to increase health inequalities and barriers to accessing appropriate care.

Baby seals can change their tone of voice

Hoover the 'talking seal' famously imitated human speech. But can baby seals already adapt their voices to sounds? Researchers have now studied seal pups only a few weeks old. The pups lowered the pitch of their voice when they heard louder noises. This vocal flexibility makes seals an excellent animal model for studying the evolution of human speech.

New method to prepare diagnostic medical radioisotope

Researchers at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) have conducted a study on preparation of low specific activity (LSA) 99Mo/99mTc generator, which has potential application prospect for the accelerator/reactor-based production of the medical isotope 99Mo.

Heterogeneous fluorescent organohydrogel proposed for dynamic anti-counterfeiting

The Smart Polymer Materials group led by Prof. Chen Tao at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of Chinese Academy of Sciences (CAS) has developed a fluorescent organohydrogel which can serve as an effective platform for the encryption and decryption of secret information, in cooperation with researchers at Beihang University. The study was published in Advanced...
