Bengal cats are prized for their appearance; the exotically marbled and spotted coats of these domestic pets make them look like small, sleek jungle cats. But the origin of those coats — assumed to come from the genes of Asian leopard cats that were bred with house cats — turns out to be less exotic. Stanford Medicine researchers, in collaboration with Bengal cat breeders, have discovered that the Bengal cats’ iridescent sheen and leopard-like patterns can be traced to domestic cat genes that were aggressively selected for after the cats were bred with wild cats. “Most ...

More than 1 million people in the United States identify as transgender; however, there is limited research on nutrition-related health outcomes for transgender people. To narrow the research gap, Mason MS, Nutrition student Eli Kalman-Rome investigated common motivations of dietary supplement use in transmasculine people. The study defined transmasculine as people on the transgender and gender-nonbinary spectrum who were assigned female at birth.  Transmasculine people reported a higher use of dietary supplements (65%) compared to the total U.S. population (22.5%), according to the study. 90% of transmasculine participants reported using supplements ...

Research that involves implanting devices into the brains of human volunteers creates a special moral obligation that extends beyond the trial period—an obligation that researchers, device manufacturers, and funders owe to the volunteers. This is the conclusion of two new essays in the Hastings Center Report that launch a series on the ethical and social issues raised by brain research.   The “Neuroscience and Society” series is supported by the Dana Foundation and will be published in open-access format online over the next three years. The series seeks to promote deliberative public engagement about neuroscience, writes Hastings Center senior ...

PHILADELPHIA -- For years, it was harder for Black patients to secure a coveted spot on the national kidney transplant waitlist because a clinical algorithm was making Black patients appear healthier than they were. After a Penn Medicine researcher exposed the problem in 2019—and showed how it exacerbated racial disparities in kidney disease—a national taskforce recommended removing race from the algorithm’s scoring, a move that has quickly been adopted throughout the country in an effort to reduce ...

ITHACA, N.Y. -- By studying individuals who spontaneously clear hepatitis C infections, a team of researchers has identified viable vaccine targets for a disease that infects 70 million worldwide with case numbers increasing every year. It turns out that a quarter of people who become infected with the hepatitis C virus clear the infection on their own without treatment, while the remaining three-quarters of people develop chronic infections that can last for years. The blood-borne disease – which causes liver cirrhosis, liver ...

For centuries, the Cerne Giant, a figure carved into a hillside in Dorset depicting a nude man carrying a club and stretching some 180 feet high, has fascinated locals and visitors to the area. The history of the giant, however, and in particular, its age, has long been a mystery. A new paper in Speculum: A Journal of Medieval Studies proposes that the Cerne Giant can in fact be dated to the early Middle Ages, and, as a result, its cultural context and significance more clearly understood.   “The Cerne Giant in its Early Medieval Context,” by authors Thomas Morcom and Helen Gittos, acknowledges that previous attempts to date the giant placed ...

25 March 2024: RCSI research has found that venetoclax, a medication currently approved for leukaemia, has benefits for patients with multiple myeloma when used in combination with another drug. This discovery offers a new avenue of treatment options for the currently incurable disease.  Multiple myeloma (MM) is a type of blood cancer that is newly diagnosed in around 400 people in Ireland each year. Despite treatment advances in recent years, it remains incurable. The search for innovative treatment strategies is crucial, particularly for patients whose cancer is resistant to standard care.  In the new study published in Haematologica, researchers at the RCSI Department of ...

Philadelphia, March 25, 2024 – Food insecurity among college students is associated with negative physical and mental health and lower academic performance and graduation rates. A recent research study in the Journal of Nutrition Education and Behavior, published by Elsevier, investigates why over half of college students eligible for the Supplemental Nutrition Assistance Program (SNAP)—the nation’s largest food assistance program—do not apply.

New research has found no evidence of a difference between recovery time and complications when comparing standard and keyhole surgical incisions for the treatment of oesophageal cancer (cancer of the gullet).  The study, led by the University of Bristol Medical School and published in the British Journal of Surgery, showed surgeons treating patients with oesophageal cancer do not need to change their practice if they have a strong preference for either procedure type. Oesophageal cancer is the tenth most common cancer globally. It causes one in 18 cancer-related deaths. ...

Key Takeaways  In a retrospective analysis of 105,517 patients with colorectal cancer, researchers found that colorectal cancer surgical cases fell by 17.3% during the first year of the pandemic.  Patients who underwent surgery for colorectal cancer in 2020 displayed more advanced stages of cancer compared to those treated in 2019.  The authors attribute these findings to multiple factors, including delays in screening, fear of COVID-19 exposure that may have prevented some people from seeking care, and disparities in cancer care that were likely exacerbated during the pandemic.  CHICAGO: While the COVID-19 pandemic is no longer considered a public ...

In nanomaterials, shape is destiny. That is, the geometry of the particle in the material defines the physical characteristics of the resulting material. “A crystal made of nano-ball bearings will arrange themselves differently than a crystal made of nano-dice and these arrangements will produce very different physical properties,” said Wendy Gu, an assistant professor of mechanical engineering at Stanford University, introducing her latest paper which appears in the journal Nature Communications. “We’ve used a 3D nanoprinting technique to produce one of the most promising ...

Scientists have discovered how honeybees can decipher dances by their hive mates that relay directions to food. The findings reveal how, in the complete darkness of the hive, each bee uses its antennae to help interpret the information communicated through the dances. It has been known for decades that honeybees do so-called waggle dances, in which their movements and orientation on the honeycomb signal the direction and distance to food outside the hive. However, until now, it was unclear how the bees gathered around a waggle dancer make sense of the information. Gaining greater insights into how bees communicate could help scientists to better understand the effects of ...

CLEVELAND—A team of researchers from the Case Western Reserve University School of Medicine has provided fresh insight into the dangers some common household chemicals pose to brain health. They suggest that chemicals found in a wide range of items, from furniture to hair products, may be linked to neurological diseases like multiple sclerosis and autism spectrum disorders. Neurological problems impact millions of people, but only a fraction of cases can be attributed to genetics alone, indicating that unknown environmental factors are important contributors to neurological disease. The new study ...

Scientists have found a “tipping point” in the evolution of fungi that throttles their growth and sculpts their shapes. The findings, published in the journal Cell Reports, demonstrate how small changes in environmental factors can lead to huge changes in evolutionary outcomes. Fungi are nature’s great composters. They wait within the forest floor to feed on fallen trees and autumn leaves, releasing essential nutrients from these plants back into the Earth.   Although fungi often ...

About The Study: The cumulative incidence of heart offer acceptance by a transplant center team was consistently lower for Black candidates than for white candidates of the same gender and higher for women than for men in this study. These disparities persisted after adjusting for candidate-, donor-, and offer-level variables, possibly suggesting racial and gender bias in the decision-making process. Further investigation of site-level decision-making may reveal strategies for equitable donor heart acceptance.  Authors: Khadijah Breathett, M.D., M.S., of Indiana University in Indianapolis, ...
