The mRNA Vaccines Are Extraordinary, but Novavax Is Even Better
At the end of January, reports that yet another COVID-19 vaccine had succeeded in its clinical trials—this one offering about 70 percent protection—were front-page news in the United States, and occasioned push alerts on millions of phones. But when the Maryland-based biotech firm Novavax announced its latest stunning trial results last week, and an efficacy rate of more than 90 percent even agai

Ubiquitination is essential for recovery of cellular activities after heat shock
Eukaryotic cells respond to stress through adaptive programs that include reversible shutdown of key cellular processes, the formation of stress granules, and a global increase in ubiquitination. The primary function of this ubiquitination is thought to be for tagging damaged or misfolded proteins for degradation. Here, working in mammalian cultured cells, we found that different stresses elicite

Bird deaths in Germany continue
Along with climate change, species extinction is one of the greatest threats to life on earth. For about 50 years, researchers have been documenting the population trends of different animal and plant groups in so-called Red Lists. The new Red List of Breeding Birds in Germany shows that the decline of birds in Germany continues unabated. More than half of the 259 permanently breeding bird species

Eawag test with fish cells replaces animal experiments
A large number of chemicals are used in everyday products, in agriculture or in industry. At some point, many of these end up in the environment. In order for these substances to be authorized for the market, manufacturers must be able to prove in advance that they are harmless to humans and nature. This is done with toxicity tests in which living creatures are exposed to the effects of the chemic

Identification of two pathways for SARS-CoV-2 entry into cells
SARS-CoV-2 is the virus that has caused the COVID-19 pandemic. Ideally, to prevent its spread, treatments should target the early stages of infection before the virus penetrates cells. A joint investigation by INRAE and Heidelberg University, Germany, has revealed the mechanisms by which the virus enters host cells. The results, published in EMBO Journal on 23rd June, show that SARS-CoV-2 uses two

Study quantifies how cyclones contribute to global climate systems
Migrating storms and local weather systems known as cyclones and anticyclones were thought to contribute to behaviors and properties of our global weather system. However, the means to probe cyclones and anticyclones were limited.

Study suggests scientists may need to rethink which genes control aging
National Institutes of Health researchers fed fruit flies antibiotics and monitored the lifetime activity of hundreds of genes that scientists have traditionally thought control aging.

Their results suggested that only about 30% of the genes traditionally a
