Bears are known for being devoted and protective of their baby cubs, but research from the University of New Hampshire shows that they may also play a significant role in shielding gray fox from predators like coyotes, who compete with the fox for food and space. The research is one of the first studies to show how black bears provide a buffer to allow other, smaller carnivores to safely co-exist.

A Cleveland Clinic study shows that survivors of COVID-19 who have moderate or severe obesity may have a greater risk of experiencing long-term consequences of the disease, compared with patients who do not have obesity. The study was recently published online in the journal of Diabetes, Obesity and Metabolism.

MUSC Hollings Cancer Center researchers are finding solutions to the aging-related changes that reduce anti-cancer immunity. Their work, published in Cell Reports, sheds light on an important pathway that cannot be ignored during cancer treatment.

Researchers have demonstrated how to use standardized reporting of clinical data for seizures caused by a variety of neurological disorders, providing fundamental baseline information that can determine what methods work best for keeping seizures under control.

The CABI-led research - which sought to assess the benefits of good farmer seed production through a case study of the Good Seed Initiative in Tanzania - reveals that while around 70% of the labour to grow African Indigenous Vegetables (AIVs) is provided by women only 10 to 30% are contract farmers who own the fields, make decisions on sales and control revenues.

Under global warming, tipping elements in the Earth system can destabilize each other and eventually lead to climate domino effects. The ice sheets on Greenland and West Antarctica are potential starting points for tipping cascades, a novel network analysis reveals. The Atlantic overturning circulation would then act as a transmitter, and eventually elements like the Amazon rainforest would be impacted. The consequences for people would reach from sea-level rise to biosphere degradation.

Research involving scientists from the University of A Coruña has succeeded in sequencing the oldest mitochondrial genome of the immediate ancestor of modern cows that has been analysed to date. The remains, some 9,000 years old, were found next to a woman. Why were they with her if cattle had not yet been domesticated? Do they belong to ancestors of today's Iberian cows?

Japanese researchers have developed and tested a prototype device -- wearable on the fingertips -- that incorporates the concept of 'light touch' to enhance the sense of balance. If widely implemented, the device should significantly reduce incidence of falls amongst seniors. The findings are published in the journal Scientific Reports on April 1.

People in both the United States and China who think others are being duped by online misinformation about COVID-19 are also more likely to support corporate and political efforts to address that misinformation, according to a new study. They are also more likely to take action themselves.

Researchers at ETH Zurich are developing a new filter membrane that is highly efficient at filtering and inactivating a wide variety of air-borne and water-borne viruses. Made from ecologically sound materials, the membrane has an appropriately good environmental footprint.

Dental care professionals are thought to be at enhanced risk of occupational exposure to SARS-CoV-2, but robust data to support this is lacking. The study 'COVID-19: Seroprevalence and Vaccine Responses in UK Dental Care Professionals,' published in the Journal of Dental Research (JDR), provides a longitudinal analysis of antibodies to SARS-CoV-2 spike glycoprotein, including early analysis of the impact of vaccination on the immune response.

An international team of researchers, led by UC Davis Health, developed a new therapeutic approach to treating psoriatic arthritis, a chronic inflammatory disease affecting the joints.

UNC School of Medicine researchers led by mucin expert Mehmet Kesimer, PhD, had previously discovered that the total mucin concentrations in the lungs are associated with COPD disease progression and could be used as diagnostic markers of chronic bronchitis, a hallmark condition for patients with COPD. Kesimer and colleagues now report that one of these mucins, MUC5AC, is more closely and reliably associated with the development of COPD than is its brother, MUC5B.

A nasal therapy, built upon on the application of a new engineered IgM antibody therapy for COVID-19, was more effective than commonly used IgG antibodies at neutralizing the COVID-19 virus in animal models, according to research recently published by The University of Texas Health Science Center at Houston (UTHealth), The University of Texas Medical Branch at Galveston (UTMB Health), the University of Houston, and IGM Biosciences, Inc.

Scientists from the Immuno-Pharmacology and Interactomics group at the Luxembourg Institute of Health (LIH), in collaboration with the Center for Drug Discovery at RTI International (RTI), have demonstrated that conolidine, a natural painkiller derived from the pinwheel flower and traditionally used in Chinese medicine, interacts with the newly identified opioid receptor ACKR3/CXCR7 that regulates opioid peptides naturally produced in the brain. The researchers also developed a synthetic analogue of conolidine, RTI-5152-12, which displays an even greater activity on the receptor.

High resolution climate models can improve predictions of extreme rainfall events. An international study involving CMCC scientists presents the first multi-model ensemble of high-resolution regional climate models and offers a promising prospect for studies on climate and climate change at local and regional scales.

There has been concern at how the pandemic has not only hit physical health and the economy but has also impacted our mental health with the possibility of increased rates of suicide.

Skoltech scientists have studied the hydroxyl defects in LiFePO4, a widely used cathode material in commercial lithium-ion batteries, contributing to the overall understanding of the chemistry of this material. This work will help improve the LiFePO4 manufacturing process to avoid formation of adverse intrinsic structural defects which deteriorate its performance.

Samara Polytech chemists have prepared a large review of methods for producing chromanes and chromenes, developed by both leading Russian scientists and world-class experts.

The Infectious Diseases group at the University of Cordoba's Department of Animal Health is conducting research into a cow's milk preparation that could be effective in controlling the coronavirus
