Wednesday 19 May 2021 - New research published today sheds important light on how the production of a key protein in the brain is controlled, which could pave the way for new treatments for a wide range of neurological conditions.
In a study part-funded by Parkinson's UK, researchers investigated a section of genetic material known as antisense long non-coding RNA (lncRNA), which helps fine-tune the production of the protein tau inside brain cells. This precision in tau regulation is crucial for smooth functioning of the nerve cells.
Brazil is the world leader in sweet orange production, but citrus cultivation in the region faces constant threats concerning the availability of water and the outbreak of diseases. New research published in the Journal of Applied Microbiology indicates that a fatty acid called hexanoic acid may help protect against one such problem: citrus canker, a bacterial infection that causes brownish eruptive lesions on the leaves, stems, and fruit of citrus trees.
NEW YORK, NY (May 19, 2021)--A new study from Columbia University and an international team of researchers identifies multiple ways to achieve the same health benefits from exercise--as long as the exercise "cocktail" includes plenty of light physical activity.
Computed tomography -- CT scanning -- which combines a series of X-ray images taken from different angles around an organism and uses computer processing to create cross-sectional images of its bones, is providing new insight into an old initiative to characterize fishes in Africa's Lake Malawi.
SARS-CoV-2 has evolved to acquire mutations on the spike protein--the part of the virus that protrudes from its surface and latches onto cells to infect them--that enhance the coronavirus' ability to bind to human cells or evade antibodies. A new study from the Centers for Genomics and Systems Biology at New York University and NYU Abu Dhabi uses computational modeling to assess the biological significance of spike protein mutations, uncovering versions of the virus that bind more tightly or resist antibodies and offering a promising public health surveillance tool.

New expert statement confirms strong links between our hormones and COVID-19
While the APP protein is well-known for its key role in Alzheimer's disease, its contribution to healthy brain function, by contrast, has remained largely unknown until now. Recently, an international research team, led by molecular biologist Prof. Dr Ulrike Müller from Heidelberg University, gained new insights on the physiological functions of the APP protein family by using a mouse model lacking APP. The absence of APP during brain development was shown to result in the malformation of important brain regions implicated in learning and memory.
Individuals are often prescribed increasing numbers of medications as they age, and while many of these prescriptions are justifiable, some may be inappropriate.
By the end of the first year of the pandemic in metropolitan Stockholm, investigators estimate that one-fifth of adults in the region previously had COVID-19. The findings, which are published in the Journal of Internal Medicine, come from analyses of anti-viral antibody responses in healthy blood donors and pregnant women.
Unbound nickel atoms and other heavy elements have been observed in very hot cosmic environments, including the atmospheres of ultra-hot exoplanets and evaporating comets that ventured too close to our Sun or other stars. A new study conducted by JU researchers reveals the presence of nickel atoms in the cold gasses surrounding the interstellar comet 2I/Borisov. The team's finding is being published in Nature on 19 May 2021.
HOUSTON - (May 19, 2021) - A new study from researchers at Rice University has found that bodily inflammation after the death of a spouse can predict future depression.
PITTSBURGH, May 19, 2021 - Specialized immune cells that accumulate in the brain in the days and weeks after a stroke promote neural functions in mice, pointing to a potential immunotherapy that may boost recovery after the acute injury is over, University of Pittsburgh School of Medicine neurologists found.
The yeast Candida albicans can cause itchy, painful urinary tract and vaginal yeast infections. For women in low-resource settings who lack access to healthcare facilities, these infections create substantial social and economic burdens. Now, researchers reporting in ACS Omega have developed color-changing threads that turn bright pink in the presence of C. albicans. When embedded in tampons or sanitary napkins, they could allow women to quickly and discreetly self-diagnose vulvovaginal yeast infections, the researchers say.
Researchers have found the elusive genetic element controlling the elongated grains and glumes of a wheat variety identified by the renowned botanist Carl Linnaeus more than 250 years ago.
The findings relating to Polish wheat, Triticum polonicum, could translate into genetic improvements and productivity in the field.
Wheat, in bread, pasta, and other forms, is a vital energy and protein source for humans. Each individual grain is nestled within the glumes and other leaf-like organs called lemma and palea which affect the grain's final size, shape, and weight.
Scientists, governments and corporations worldwide are racing against the clock to fight climate change, and part of the solution might be in our soil. By adding carbon from the atmosphere to depleted soil, farmers can both increase their yields and reduce emissions. A cover story in Chemical & Engineering News, the weekly newsmagazine of the American Chemical Society, explores what it would take to get this new practice off the ground.
