Quitting sugar completely may not be as beneficial as many people think. New research presented Saturday at ENDO 2026, the Endocrine Society’s annual meeting in Chicago, suggests that completely eliminating sugar from the diet may have unexpected effects on gut and metabolic health. Researchers at Dasman Diabetes Research Institute in Kuwait looked at what happens when mice are fed a low-fat diet without sucrose, a common form of sugar. In this study, these animals were compared to a control group that was fed a low-fat diet containing sucrose for 16 weeks. “Complete removal of sucrose from a low-fat diet can…

Recent research published in Journal of Clinical Psychiatry Our results suggest that a single dose of psilocybin combined with psychological support may quickly and safely reduce chronic suicidal ideation in adults with severe depression. The findings of this study provide evidence that psychedelic-assisted therapy tends to provide durable relief in individuals who have not responded to standard psychiatric treatment. Chronic suicidal ideation is a serious challenge in psychiatric care. Symptoms often persist even when patients receive standard treatments and intensive drug trials. Traditional interventions, such as standard antidepressants and cognitive behavioral therapy, tend to be effective for many people, but…

Massive stars produce light and heat through nuclear fusion, a process that releases vast amounts of energy from their cores. But eventually, the largest stars will run out of fuel. When that happens, the outward pressure created by the radiation is no longer strong enough to resist gravity. The star begins to collapse under its own weight until, in theory, all of its mass is compressed into a single point known as a singularity. Although black holes are widely accepted by physicists, they still raise serious questions. How can the mass of billions of suns be squeezed into an infinitely…

One of the most widely cited stories about Yellowstone’s wolves is facing new scrutiny. A new peer-reviewed analysis Earth ecology and conservation claims that a high-profile 2025 study vastly exaggerated the ecological impact of wolf recovery in Yellowstone National Park. Researchers from Utah State University and Colorado State University say earlier studies relied on flawed methodology and led to exaggerated conclusions about how wolves affected the park’s ecosystem. “Ripple and colleagues argued that carnivore recovery has created one of the most powerful trophic cascades in the world,” said Dr. Daniel McNulty, lead author of the new analysis and a wildlife…

Parrots are famous for their ability to imitate human speech, but do they use names the same way we do? New research suggests the answer may be yes. Rather than traveling to tropical habitats to record parrots in the wild, as researchers have done in previous studies, Laurin Benedict, a biology professor at the University of Northern Colorado, took a different approach. She focused on parrots that coexist with humans, birds that regularly hear and repeat words that include people’s names. Working with longtime collaborator Christine Darling of the University of Pittsburgh at Johnstown and researchers in Austria, Benedict examined…

For many Americans, middle age is even more difficult than it was for previous generations. People born in the 1960s and early 1970s reported higher levels of loneliness and depression, as well as poorer memory and physical fitness, compared to those born before that. What makes this trend particularly noteworthy is that it is not occurring to the same extent in many other wealthy countries. In some countries, particularly in Northern Europe, health and well-being in midlife improves rather than declines over time. To understand why the United States appears to be moving in a different direction, Arizona State University…

The new test provides a much more complete picture of your DNA than current standard diagnostics and more often leads to a diagnosis. This test can replace the other 15 tests, making it faster and more efficient. Researchers at Radboud University Medical Center recommend the test be adopted everywhere as first-line treatment for rare genetic diseases, in the New England Journal of Medicine. A condition that affects fewer than 1 in 2,000 people is considered rare. Yet, up to 400 million people worldwide are affected by rare diseases, of which there are more than 7,000 types. 80% of these have…

Researchers at Amsterdam UMC, in collaboration with other hospitals, have successfully completed the first-ever Phase 3 study of in vivo CRISPR therapy. In this large, double-blind Phase 3 trial, 80 patients with hereditary angioedema were randomly assigned to receive either CRISPR therapy or a placebo. CRISPR therapy is a medical technology that allows doctors to precisely correct errors in a cell’s DNA to treat certain genetic diseases. Study leader Danny Kohn is enthusiastic: “This study proves that this treatment is indeed effective and safe. This confirmation is exactly what regulators need to approve the first in vivo CRISPR gene editing…

With more than 40% of American teens reporting ongoing feelings of sadness and hopelessness, leading child psychologists say grandparents and extended family members have an important role to play. Dr. Kenneth Barish, a professor of clinical psychology at Weill Cornell Medical College, argues that the loss of extended family support is contributing to what the U.S. Surgeon General calls a long-term crisis in the mental health of children and adolescents. We did not evolve to raise our children with little extended family and community support, as most American parents do today. Children need grandparents and always will. ” …

A major new study led by Yale University is helping to fill a long-standing gap in genetics research by providing one of the most comprehensive surveys to date of human genetic diversity in Oceania. Although the South Pacific is home to a highly diverse population, people from this region have historically been underrepresented in large-scale genetic studies. Much of the genomics research has focused on populations of European descent, leaving important questions about human history and biology unanswered. “Significant underrepresentation of Oceanians limits our understanding of human evolution and has the potential to further exacerbate health disparities as genomic research…
