| Protons are probably actually smaller than long thought Posted: 06 Feb 2022 12:44 PM PST A few years ago, a novel measurement technique showed that protons are probably smaller than had been assumed since the 1990s. The discrepancy surprised the scientific community; some researchers even believed that the Standard Model of particle physics would have to be changed. Physicists have now developed a method that allows them to analyze the results of older and more recent experiments much more comprehensively than before. This also results in a smaller proton radius from the older data. So there is probably no difference between the values - no matter which measurement method they are based on. |
| Venomous Australian sea anemone may lead to life-saving drugs Posted: 06 Feb 2022 12:44 PM PST An entirely new toxic compound found in an Australian tropical sea anemone is being analysed as a potential new drug therapy, after it was discovered by biomolecular scientists during investigation of the species' multiple venoms. |
| Underwater 'breathing' plants could be key to stress-resistant crops Posted: 06 Feb 2022 12:44 PM PST Wetland plants have a high tolerance against flooding due to the formation of 'lysigenous aerenchyma,' air channels that help transfer gases to the submerged roots. These channels also help the plant withstand drought and nutrient deficiency. Now, scientists investigate the underlying mechanism of aerenchyma formation to understand the phenomenon better, opening doors to the development of crops that are resilient against extreme weather changes. |
| One in four Australian workers suffer ‘ringing ears’, survey shows Posted: 06 Feb 2022 12:44 PM PST As many as half a million Australians are suffering from constant tinnitus, with farmers, automotive workers, transport drivers, construction workers and other trades people at the greatest risk, a national survey has found. |
| Preventing pandemics costs far less than controlling them Posted: 04 Feb 2022 01:17 PM PST An analysis by epidemiologists, economists, ecologists and biologists at 21 institutions finds we could reduce the risks of future pandemics by investing as little as 1/20th of the losses incurred so far from COVID into conservation measures designed to stem the spread of zoonotic viruses from wildlife to humans in the first place. This includes funding programs to train more veterinarians, create a global database of virus genomics, and end tropical deforestation and wildlife trafficking. |
| Posted: 03 Feb 2022 01:11 PM PST In a new study, researchers show a correlation between vitamin D deficiency and COVID-19 severity and mortality. The study is among the first to analyze vitamin D levels prior to infection, which facilitates a more accurate assessment than during hospitalization, when levels may be lower secondary to the viral illness. |
