ITHACA, N.Y. – Why do some corporate expressions of solidarity with marginalized groups register as genuine, while others seem performative or even backfire? An analysis of statements by Fortune 500 companies following the 2020 police killing of George Floyd finds that costly actions, such as donating money to social justice groups, aren’t enough to convey allyship to Black Americans. Companies must also demonstrate a consistent, long-term commitment to diversity and racial equity, according to research co-authored by James T. Carter,  assistant ...

COLUMBUS, Ohio – A consideration of how mountains influence El Niño and La Niña-induced precipitation change in western North America may be the ticket to more informed water conservation planning along the Colorado River, new research suggests. The study, coinciding with a recent shift from a strong La Niña to a strong El Niño, brings a degree of precision to efforts to make more accurate winter precipitation predictions in the intermountain West by comparing 150 years of rain and snow data with historic El Niño-Southern Oscillation patterns. Overall, the analysis shows ...

ITHACA, N.Y. – Inspired by a small and slow snail, scientists have developed a robot protype that may one day scoop up microplastics from the surfaces of oceans, seas and lakes. The robot’s design is based on the Hawaiian apple snail (Pomacea canaliculate), a common aquarium snail that uses the undulating motion of its foot to drive water surface flow and suck in floating food particles. Currently, plastic collection devices mostly rely on drag nets or conveyor belts to gather and remove larger plastic debris from water, but they lack the fine scale required for retrieving microplastics. These tiny particles of plastic can be ingested ...

Researchers at Weill Cornell Medicine have found that controlling high blood pressure may not be enough to prevent associated cognitive declines. The findings point to an immune protein called cytokine IL-17 as a culprit for inducing dementia and suggest new approaches to prevent damage to brain cells. The study, published on Dec. 4 in Nature Neuroscience, uncovered a new mechanism involving increased levels of IL-17 in the brain which suppressed blood flow to the brain and induced cognitive impairment in a preclinical model of salt-sensitive high blood pressure. “An ...

At last year’s COP15 conference in Montreal, the Government of Canada set the goal of conserving 30 percent of the country’s land and water by 2030. In a new study in Nature Communications, a group of McGill University researchers have sought to understand how well our existing protected lands preserve Canadian species, how many species we could save if we reach our 30 by 30 targets, and what factors impact our ability to safeguard species in future conserved areas. Lead author Isaac Eckert, a McGill PhD candidate in Biology, answered some questions about his research. This interview has been edited and condensed for clarity. What ...

Toronto, ON, December 4, 2023 – There was a disproportionate rise in pediatric eating disorder hospitalizations among males, younger adolescents, and individuals with eating disorder diagnoses other than anorexia or bulimia, according to a new study from researchers at The Hospital for Sick Children (SickKids) and ICES.  This large, population-based study spanned a 17-year period in Ontario, Canada (2002-2019), and tracked an overall increase of 139% in eating disorder hospitalizations among children and adolescents, with a total of 11,654 hospitalizations. The number of co-occurring mental illness diagnoses for ...

Contrary to current understanding, the brains of human newborns aren’t significantly less developed compared to other primate species, but appear so because so much brain development happens after birth, finds a new study led by UCL researchers. The study, published in Nature Ecology & Evolution, found that humans are born with brains at a development level that’s typical for similar primate species, but the human brains grow so much larger and more complex than other species after birth, it gives the false impression that human newborns are underdeveloped, or “altricial.” Lead author Dr Aida ...

About The Study: In this prespecified secondary analysis of outcomes of 32,000 participants in a randomized clinical trial and post-trial up to 23 years later among adults with hypertension and coronary heart disease risk factors, cardiovascular disease mortality was similar between all three antihypertensive treatment groups (thiazide-type diuretic, calcium channel blocker, or angiotensin-converting enzyme [ACE] inhibitor). ACE inhibitors increased the risk of stroke outcomes by 11% compared with diuretics, and this effect persisted well beyond the trial period.  Authors: Jose-Miguel ...

About 20 % of patients whose medical records showed them as being alive with a serious illness were in fact deceased according to California data, leading to hundreds of unnecessary interactions such as appointment reminders, prescription refills and other kinds of wasteful outreach that strain resources and healthcare workers’ time. The data gap is due to California law that makes these full death data available only “for purposes of law enforcement or preventing fraud,” according to a UCLA-lead research team. Even a real-time death database maintained by the National Association for Public Health ...

Ketamine – an anesthetic also known for its illicit use as a recreational drug – has undergone a thorough reputational rehabilitation in recent years as the medical establishment has begun to recognize its wide-ranging therapeutic effects. The drug is increasingly used for a range of medical purposes, including as a painkiller alternative to opioids, and as a therapy for treatment-resistant depression. In a new study published in the journal Cell Reports, Columbia biologists and biomedical engineers mapped ketamine’s effects on the brains of mice, and found that repeated use over extended periods of time leads to widespread structural changes in the brain’s ...

Two new studies led by researchers from the UCLA Jonsson Comprehensive Cancer Center give insight into how cells use energy to influence the way prostate tumors survive and grow — advancements that can help explain why some prostate cancers become resistant to hormone therapy, the most commonly used treatment for men with advanced stages of the disease. Hormone therapy, also known as antiandrogen therapy, plays a crucial role in temporarily halting the growth of prostate cancer cells. Over time, however, the majority of patients eventually see their cancer return and progress, underscoring the pressing need for continued advancements to enhance clinical ...

Many of the most potent human oncoproteins belong to a class of proteins called transcription factors, but designing small molecule drugs that target transcription factors is a major challenge. An international team of researchers from the Institute for Research in Biomedicine (IRB Barcelona), the Max Planck Institute for Molecular Genetics (MPIMG), BC Cancer (University of British Columbia) and other institutions has discovered a potential way to target the androgen receptor, the most prominent oncogenic transcription factor in prostate cancer, based on its propensity to form droplets also known as condensates. The results described ...
