Wildlife conservation efforts could suffer because toxic online rows about trophy hunting are becoming increasingly abusive, ecologists have warned. Scientists analysed hundreds of tweets about trophy hunting and found that 7% were abusive. This is a similar proportion to content on partisan topics on social media platforms known to highlight extreme viewpoints. The findings, by conservation scientists at the University of Reading and the University of Sheffield, are published today (9 March) in the journal ...

Changing environmental conditions may threaten marine mammal populations by making it harder to find prey, and a new study shows how small, gradual reductions in prey could have profound implications for animal populations. The reproductive success of female elephant seals depends on their ability to find prey and put on weight during their months-long foraging migrations. Researchers at UC Santa Cruz studied the relationships between elephant seal behavioral strategies in the open ocean, weight gain, and lifetime success at producing pups. Their findings, published March 8 in Ecology Letters, reveal a sharp threshold in the relationship between ...

SAN FRANCISCO, CA—March 8, 2023—When it comes to oxygen, you can have too much of a good thing. Breathing air that contains higher levels of oxygen than the usual 21 percent found in Earth’s atmosphere can cause organ damage, seizures, and even death in people and animals, particularly if it’s in excess of the body’s oxygen needs. Until now, however, scientists have mostly speculated about the mechanisms behind this phenomenon, known as oxygen toxicity, or hyperoxia. Now, researchers at Gladstone Institutes have discovered how excess oxygen changes a handful of proteins in our cells that ...

Excessive iron absorption by tumor cells in the digestive tract is known to play a major role in driving colorectal cancer – the third most prevalent and third leading cause of cancer deaths in the U.S. In a new study published in the journal Advanced Science, University of New Mexico researchers describe the part played by the transferrin receptor (TFRC) gene in the growth of colorectal cancer tumors. Iron is absorbed into intestinal cells both from the bloodstream and from iron-rich foods, such as red meat, said Xiang Xue, PhD, assistant professor ...

While the crowds swarm around Old Faithful to wait for its next eruption, a little pool just north of Yellowstone National Park’s most famous geyser is quietly showing off its own unique activity, also at more-or-less regular showtimes. Instead of erupting in a towering geyser, though, Doublet Pool cranks up the bass every 20 to 30 minutes by thumping. The water vibrates and the ground shakes. Doublet Pool’s regular thumping is more than just an interesting tourist attraction. A new study led by University of Utah researchers shows that the ...

WEST LAFAYETTE, Ind. — Americans likely are receiving smaller tax refunds than they have in recent years, and most people will not be going out to spend this money, according to the February 2023 Consumer Food Insights Report. This month’s report also looks more closely at religious demographics and includes new data on frozen food preferences. The survey-based report out of Purdue University’s Center for Food Demand Analysis and Sustainability assesses food spending, ...

A global dataset of ocean plastic pollution between 1979 and 2019 reveals a rapid and unprecedented increase in ocean plastics since 2005, according to a study published March 8, 2023 in the open-access journal PLOS ONE by Marcus Eriksen from The 5 Gyres Institute, USA, and colleagues.  Understanding plastic accumulation in the oceans to date could provide a critical baseline to help address this form of pollution. Previous studies have focused primarily on northern-hemisphere oceans near the world’s most industrialized nations, ...

A new analysis of crime statistics near hundreds of places of worship in Washington, D.C., shows that these sites are associated with higher levels of violent and property crime—even after accounting for other factors commonly linked with crime. James Wo of the University of Iowa, U.S., presents these findings in the open-access journal PLOS ONE on March 8, 2023. Prior research has established that places of worship foster social ties and community actions for the common good, suggesting that these sites would reduce crime in their neighborhoods. However, few studies have addressed the hypothesized ...

New study finds obstacles can trap rolling microparticles in fluid Through simulations and experiments, physicists attribute the trapping effect to stagnant pockets of fluid, created by hydrodynamics Random motions of the molecules within the fluid then ‘kick’ the microroller into a stagnant pocket, effectively trapping it Size of the obstacle also controls how easy it is to trap a microroller and how long it remains trapped EVANSTON, Ill. — When physicists steered a tiny microparticle toward a cylindrical obstacle, they expected one of two outcomes to occur. The particle would either collide into the ...

Scientists from the Trinity Biomedical Sciences Institute (TBSI) have shed new light on ageing processes in the brain. By linking the increased presence of specialised immune cells to conditions such as Alzheimer’s disease and traumatic brain injury for the first time, they have unearthed a possible new target for therapies aimed at treating age-related neurological diseases. The research, which benefited from a collaboration with experts at the University of Maryland School of Medicine and focused ...

Research in animal models has demonstrated that stem-cell derived heart tissues have promising potential for therapeutic applications to treat cardiac disease. But before such therapies are viable and safe for use in humans, scientists must first precisely understand on the cellular and molecular levels which factors are necessary for implanted stem-cell derived heart cells to properly grow and integrate in three dimensions within surrounding tissue. New findings from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) make it possible ...

Coffee is important to the economies of coffee producing regions. A study published in PLOS Climate by Doug Richardson at CSIRO Oceans & Atmosphere, Hobart, Tasmania, Australia and colleagues suggests that climate change may significantly affect land where coffee is cultivated. Coffee plants are sensitive to climate variability and change. However, the impact of synchronous climate hazards occurring in multiple areas important for coffee production is unknown. In order to better understand how large-scale climate modes such as El Niño ...

RIVERSIDE, Calif. -- Their popularity makes celebrities easy to spot. Strangers, however, can also get mistaken for celebrities, resulting in cases of false “celebrity sightings.” In attempting to explain the contradiction, a University of California, Riverside, study reports that celebrity faces are remembered more precisely but less accurately. Precision, in this context, refers to how memories for a particular face resemble each other over repeated memory retrievals, which can be likened to the clustering of arrows on a target in archery. Accuracy measures ...

New Haven, Conn. — The constant evolution of new COVID-19 variants makes it critical for clinicians to have multiple therapies in their arsenal for treating drug-resistant infections. Researchers have now discovered that a new class of oral drugs that acts directly on human cells can inhibit a diverse range of pathogenic SARS-CoV-2 strains. In their newly published study, the team found a novel mechanism through which the gene that expresses angiotensin converting enzyme-2 (ACE-2)—the cellular receptor to which SARS-CoV-2 ...
