Mother fence lizards that experience stress during pregnancy give birth to male offspring with shortened telomeres, or bits of non-coding DNA that cap the ends of chromosomes, according to a Penn State-led study. Shorter telomeres are associated with decreased lifespan in humans; therefore, the team's findings may have implications for human longevity.
Do users, customers, employees, and others have a right to know how companies that use algorithms make their decisions? In a new analysis, researchers explore the moral and ethical foundations to such a right. They conclude that the right to such an explanation is a moral right, then address how companies might do so.
Scientists at the National Institutes of Health determined that stomach inflammation is regulated differently in male and female mice after finding that androgens, or male sex hormones, play a critical role in preventing inflammation in the stomach. The finding suggests that physicians could consider treating male patients with stomach inflammation differently than female patients with the same condition. The study was published in Gastroenterology.
A new method to analyse the blood thinning drug Heparin has been developed that can pinpoint contaminants more accurately and quickly, providing greater quality control and safety.
Of the over 400 climate scenarios assessed in the 1.5°C report by the Intergovernmental Panel on Climate Change (IPCC), only around 50 scenarios avoid significantly overshooting 1.5°C. Of those only around 20 make realistic assumptions on mitigation options, for instance the rate and scale of carbon removal from the atmosphere or extent of tree planting, a new study shows. All 20 scenarios need to pull at least one mitigation lever at "challenging" rather than "reasonable" levels.
Researchers have develop first-in-class inhibitors against ASH1L, a key protein in the development and progression of leukemia.
The study suggests that the SWI/SNF complex may be a tumour suppressor and DNA-RNA hybrids could be an important source of tumour generation
Breathing exercises helps to better supply the brain with oxygen and helps the reticular formation to better cope with its role. When the reticular formation receives enough oxygen, it begins to better regulate the child's state of activity.
Quantum mechanics is famous for its indeterminism, but we can usually use probabilities to quantify our uncertainty about future observations. However, a team of researchers at the University of Vienna, the IQOQI Vienna (Austrian Academy of Sciences) and the Perimeter Institute for Theoretical physics have recently shown that in certain extreme quantum scenarios it is not possible to make such probabilistic predictions, provided that certain key assumptions of quantum mechanics hold true.
The COVID-19 lockdown was a catalyst for many older people to embrace technology, reconnect with friends and build new relationships with neighbours, according to University of Stirling research.
