Almost one in three adults aged 45 and older who had both TB and COVID-19 died during a pandemic cohort study in NYC between March 2020 and June 2022

Physicists at The Australian National University (ANU) are using nanoparticles to develop new sources of light that will allow us to “peel back the curtain” into the world of extremely small objects – thousands of times smaller than a human hair – with major gains for medical and other technologies.  The findings, published in Science Advances, could have major implications for medical science by offering an affordable and effective solution to analyse tiny objects that are too small for microscopes to see, let alone the human eye. The work could also be beneficial for the semiconductor industry ...

Keeping tree diversity intact in Canada’s many forests over the long term can help increase carbon capture and mitigate climate change, according to a new University of Alberta study.  The study, published in Nature, is the first of its kind to show the sustained benefits of tree diversity on a large spatial scale, in terms of storing carbon and nitrogen in the soil. It reinforces the importance of biodiversity conservation in forests, says Xinli Chen, lead author on the paper and postdoctoral fellow in the Faculty of Agricultural, ...

Andy Weir’s bestselling 2011 book, The Martian, features botanist Mark Watney’s efforts to grow food on Mars after he becomes stranded there. While Watney’s initial efforts focus on growing potatoes, new research presented at the 54th Lunar and Planetary Science Conference by a team of interdisciplinary researchers from the U of A suggests future Martian botanists like Watney may have a better option: growing rice. As outlined in the team’s abstract, Rice Can Grow and Survive in Martian ...

ITHACA, N.Y. -- New research from a multidisciplinary team helps to illuminate the mechanisms behind circadian rhythms, offering new hope for dealing with jet lag, insomnia and other sleep disorders. Using innovative cryo-electron microscopy techniques, the researchers have identified the structure of the circadian rhythm photosensor and its target in fruit flies (Drosophila melanogaster), one of the major organisms used to study circadian rhythms. The research, “Cryptochrome-Timeless Structure Reveals Circadian Clock Timing ...

The Buck Institute for Research on Aging announces that Ashley Webb, PhD, will join its faculty as an associate professor on August 1, 2023. Webb’s research is focused on the molecular mechanisms underlying stem cells and brain aging.  She joins the Buck from Brown University, where she is currently an associate professor in the Department of Molecular Biology, Cell Biology and Biochemistry. Webb uses a combination of mouse models, cell culture approaches and genomics technologies to investigate the epigenetic and transcriptional mechanisms that preserve healthy ...

    Preserving the diversity of forests assures their productivity and potentially increases the accumulation of carbon and nitrogen in the soil, which helps to sustain soil fertility and mitigate global climate change.   That's the main takeaway from a new study that analyzed data from hundreds of plots in Canada's National Forest Inventory to investigate the relationship between tree diversity and changes in soil carbon and nitrogen in natural forests.   Numerous biodiversity-manipulation experiments have collectively suggested that ...

Researchers from Tokyo Medical and Dental University (TMDU) identify a novel mechanism by which cells adhere more strongly to their surrounding matrix in response to stress Tokyo, Japan – The DNA molecules in our cells can be damaged by various extrinsic and intrinsic factors called genotoxic stressors; persistent and unchecked damage can lead to developing diseases like cancer. Fortunately, our cells don’t sit idly by and let this happen. In a recent article published in Cell Death & Disease, a team ...

Researchers have established that biological sex plays a role in determining an individual’s risk of brain disorders. For example, boys are more likely to be diagnosed with behavioral conditions like autism or attention deficit disorder, whereas women are more likely to suffer from anxiety disorders, depression, or migraines. However, experts do not fully understand how sex contributes to brain development, particularly in the context of these diseases. They think, in part, it may have something to do with the differing sizes of certain brain regions. University ...

HA NOI, Viet Nam (April 26, 2023) – A new study led by the Wildlife Conservation Society (WCS) identified a viral hotspot in Viet Nam where bat roosting sites, bat guano harvesting, and pig farms are all in close proximity. The findings of this collaborative One Health study, described in the latest issue of the journal Viruses, have important implications for public health and wildlife conservation. The authors say that the collection of guano – commonly used as a fertilizer – if not stopped ...

New research has found that it is possible to capture the impact of a meal on metabolism outside of a lab environment. Published in the Journal of the International Society of Sports Nutrition and led by researchers at Anglia Ruskin University (ARU) in Cambridge, England, the study evaluated Lumen, which the manufacturers claim is the first device to allow people to monitor metabolic fuel use at home. The research – the first applied study to investigate the practical use of this handheld breath device – was split into ...
