Talcum powder, a coconut oil-cocoa butter beeswax mixture, and petroleum jelly provide the best skin protection for long-term PPE use, say scientists.
The first stages of placental development take place days before the embryo starts to form in human pregnancies. The finding highlights the importance of healthy placental development in pregnancy, and could lead to future improvements in fertility treatments such as IVF, and a better understanding of placental-related diseases in pregnancy.
High levels of air pollution are forcing people inside to consume more electricity, subsequently causing even greater environmental problems by increasing greenhouse gas emissions.
Researchers from the University of Tsukuba have found a fungal-bacterial relationship that allows bacteria to travel along fungal highways and supply the fungus with thiamine (vitamin B1), which is essential to most organisms. Thiamine provided by the bacteria helped the fungal filaments to grow, and the highways let the bacteria travel farther than otherwise possible. Research in this area could be applied to settings ranging from fermentation to plant and human disease mechanisms.
The white, fluffy layer that covers Camembert is made of a mould resulting from human selection, similar to the way dogs were domesticated from wolves. A collaboration involving French scientists from the CNRS has shown that the mould Penicillium camemberti is the result of a domestication process.
Prof. Bimberg's group at Bimberg Chinese-German Center for Green Photonics Changchun at Institute of Optics, Fine Mechanics, and Physics, Chinese Academy of Sciences has developed VCSELs emitting at 850 nm, 880 nm, 910 nm, 940 nm, which were optimized to achieve 50+ Gb/s, enabling 200+ Gb/s data transmission across a multimode fiber. This was based on the PAM2-modulation scheme without any kind of predistortion leading to a spectral efficiency around 2 bit.
A comprehensive search of genetic variation databases has revealed no significant differences across populations and ethnic groups in seven genes associated with viral entry of SARS-CoV-2.
Researchers from Yale-NUS College and Carnegie Mellon University (CMU) find support for new hypotheses: that tarantulas' vibrant blue colours may be used to communicate between potential mates, while green colouration confers the ability to conceal among foliage. Their research also suggests that tarantulas are not as colour-blind as previously believed, and that these arachnids may be able to perceive the bright blue tones on their bodies.
Tokyo Medical and Dental University (TMDU) researchers have successfully attached the cancer cell-targeting antibody Trastuzumab to a previously reported supermolecule that induces autophagic cell death. The antibody-drug conjugate (ADC) selectively targeted HER2-overexpressing cancer calls and reduced cell viability at lower concentrations than free supermolecule drug. It is hoped that the ADC will provide a targeted autophagic death route for treating apoptosis resistant cancer cells in vivo, and ultimately provide an alternate approach in the clinic.
Every living cell maintains a voltage across the cell membrane that results from differences in the concentrations of charged ions inside and outside the cell. In an impressive proof-of-concept demonstration, an interdisciplinary team of scientists has developed a bioelectronic system driven by a machine learning algorithm that can shift the membrane voltage in living cells and maintain it at a set point for 10 hours.
