A lonely rhinoceros at a Bangladesh zoo is looking for new love after losing her partner seven years ago, but pandemic travel restrictions are hampering her keeper's attempts to play matchmaker.

For most people, the word "vampire" brings to mind Dracula or perhaps slayers such as Blade or Buffy; or maybe even the vampire bats of South America. Few will think of a small and rather lovely bird—the finch.

The US fishing and seafood sector years generated more than $200 billion in annual sales and supported 1.7 million jobs in recent years. It experienced broad declines in 2020 as a result of the COVID-19 public health crisis, according to a new NOAA Fisheries analysis released today.

Plant pathologists working at universities across 26 corn-producing states in the United States and in Ontario, Canada, compiled data about annual corn reductions caused by diseases. Estimated loss from each disease varied greatly by region.

Girls who are emotionally neglected or severely sexually abused early in their lives report riskier sexual behaviors during adolescence, Mount Sinai researchers report. The findings highlight the need–and suggest the potential for tailored approaches–to promote healthy sexual development in vulnerable populations.

Perceived low-grade forms of workplace mistreatment, such as avoiding eye contact or excluding a coworker from conversation, can amplify suicidal thoughts in employees with mood disorders, based on a West Virginia University study.

Use of the diabetes drug metformin — before a diagnosis of COVID-19 — is associated with a threefold decrease in mortality in COVID-19 patients with Type 2 diabetes, according to a racially diverse study at the University of Alabama at Birmingham. Diabetes is a significant comorbidity for COVID-19. This beneficial effect remained, even after correcting for age, sex, race, obesity, and hypertensi

A new CMCC global and free access dataset of 35 bioclimatic indicators just presented on Nature Scientific Data. It will complement and enlarge the availability of spatialized bioclimatic information, crucial aspect in many ecological and environmental studies and for several disciplines, including forestry, biodiversity conservation, plant and landscape ecology.

If the start of the new year has you thinking about ways to improve your physical and emotional well being, the first thing you need to do is figure out how to get better sleep . After all, you can drink a gallon of coffee to pump yourself up in the morning and eat a whole bag of CBD gummies to calm yourself down in the evening, but the reality is it’s biologically impossible to achieve peak phys

Analysis: some say lateral flow tests could help cut outbreaks, but others argue they offer false reassurance Regulator refuses to approve mass Covid testing at schools in England Coronavirus – latest updates See all our coronavirus coverage The education secretary, Gavin Williamson, has put mass testing for coronavirus at the heart of his strategy to reopen schools after the lockdown. It is a co

Leading cancer expert solve long-standing question of how various types of mutations in just one gene cause different types of diseases.

Illinois residents value efforts to reduce watershed pollution, and they are willing to pay for environmental improvements, according to a new study from agricultural economists.

Research has revealed new insight into the biological mechanisms of the long-term positive health effects of breastfeeding.

COVID-19 has resulted in a staggering death toll in the United States: over 215,000 by mid-October 2020, according to the Centers for Disease Control and Prevention. Black and Latino Americans have experienced a disproportionate burden of COVID-19 morbidity and mortality, reflecting persistent structural inequalities that increase risk of exposure to…

Immune response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection during the current pandemic remains a field of immense interest and active research worldwide. Although the severity of acute infection may depend on the intensity of innate and adaptive immunity, leading to higher morbidity and mortality, the longevity of…

We refer to an article pointedly titled “CSF1R inhibition by a small-molecule inhibitor is not microglia specific; affecting hematopoiesis and the function of macrophages” in PNAS (1). This Brief Report addresses a straw man. Thirty years of studies on CSF1 signaling in peripheral populations, assessed via small-molecule inhibitors, antibodies, and…

Our study (1) was designed to provide definitive direct data to the microglia community that PLX5622 does not act solely on microglia but also affects other peripheral macrophage populations. Many microglia papers have assumed or claimed that CSFR1 inhibition has no to minimal effects on peripheral immune cells.* The nonmicroglia…

Haematopoiesis relies on tightly controlled gene expression patterns as development proceeds through a series of progenitors. While the regulation of hematopoietic development has been well studied, the role of noncoding elements in this critical process is a developing field. In particular, the discovery of new regulators of lymphopoiesis could have…

Almost 150 papers about brain lymphatics have been published in the last 150 years. Recently, the information in these papers has been synthesized into a picture of central nervous system (CNS) “glymphatics,” but the fine structure of lymphatic elements in the human brain based on imaging specific markers of lymphatic…

Triggering receptor expressed on myeloid cells 2 (TREM2) sustains microglia response to brain injury stimuli including apoptotic cells, myelin damage, and amyloid β (Aβ). Alzheimer’s disease (AD) risk is associated with the TREM2R47H variant, which impairs ligand binding and consequently microglia responses to Aβ pathology. Here, we show that TREM2…

Warming ocean waters could reduce the ability of fish, especially large ones, to extract the oxygen they need from their environment, researchers report. For their new study in the Proceedings of the National Academy of Sciences , the researchers developed a new model to determine how water temperature, oxygen availability, body size, and activity affect metabolic demand for oxygen in fish. The r

A survey of Californians shows that exposure to violence has pervasive social and emotional impacts on people, especially when firearms are involved.

Galileo once observed that nature is written in math. Biology might be written in words. Natural-language processing (NLP) algorithms are now able to generate protein sequences and predict virus mutations, including key changes that help the coronavirus evade the immune system. The key insight making this possible is that many properties of biological systems can be interpreted in terms of words

Computational materials science experts have enhanced an algorithm that borrows its approach from the nesting habits of cuckoo birds, reducing the search time for new high-tech alloys from weeks to mere seconds.

By combining large amounts of low-fidelity data with smaller quantities of high-fidelity data, nanoengineers have developed a new machine learning method to predict the properties of materials with more accuracy than existing models. Crucially, their approach is also the first to predict the properties of disordered materials — those with atomic sites that can be occupied by more than one element

Prospect of tighter rules recedes despite NHS remaining under pressure and death rate rising

Why do some hosts' immune systems reject tumors easily, while others have a harder time doing so? It depends on the types of the immune cells known as CD8 T cells and how a host's specific T cells match up with the neoantigens present in the tumor.
