High blood pressure boosts risk of common heart valve disorder

Researchers found a significant association between elevated systolic blood pressure and the development of mitral regurgitation, a condition where the heart valve leaks. The study suggests that controlling blood pressure may be crucial in preventing this common heart valve disorder.

Tropical beetles face extinction threat

A recent study has found that tropical high-altitude beetles are at risk of extinction due to climate change. The research, conducted in the Brazilian Atlantic Rainforest, revealed that two plant-eating beetle groups - weevils and leaf beetles - are highly specialised to high altitudes and may disappear in a warmer world.

New assay may boost targeted treatment of non-Hodgkin lymphoma

A new gene expression profiling assay has been developed to enhance the diagnosis and treatment of non-Hodgkin lymphoma, particularly diffuse large B-cell lymphoma. The assay can differentiate between three major subtypes associated with different outcomes, including germinal center B-cell-like and activated B-cell-like subtypes.

New study: nearly half of US medical care comes from emergency rooms

A new study by University of Maryland School Medicine researchers found that nearly half of all US medical care is delivered by emergency departments. Emergency department visits increased by 44% over a 14-year period, with African-American patients and those without insurance using these services at a higher rate.

Corticosteroids aid healing -- if the timing is right

A new study from Linköping University finds that corticosteroids can improve tendon healing if administered at the correct timing. The research reveals that inflammation must subside before new tissue formation begins. When given after the early inflammatory phase, corticosteroids significantly enhance tendon strength in rats.

High blood pressure linked to common heart valve disorder

A new study from The George Institute for Global Health at the University of Oxford found a strong link between high blood pressure and mitral regurgitation, a condition that makes the heart less efficient at pumping blood. Lowering blood pressure through exercise, diet or medication may reduce the risk of developing this condition.

Wearables to boost security of voice-based log-in

Researchers developed a wearable device called VAuth that creates a unique and secure signature using speech-induced vibrations on the user's body. The technology has achieved a 97-percent detection accuracy and successfully thwarts various practical attacks, making it a promising solution to enhance voice authentication security.

Microbes leave 'fingerprints' on Martian rocks

Researchers have discovered that a specific microbe can oxidize and metabolize metals from synthetic Martian regolith simulants, leaving behind unique signatures. This finding could enable the extraction of metals from asteroids and other celestial bodies using biological methods.

Risk of cesarean section is heritable

A recent study by Philipp Mitteroecker and colleagues used the cliff edge model to predict that women born by Caesarean are more likely to develop FPD in their own childbirth, with a 2.8 times higher risk compared to women born vaginally.

Most medical students overconfident, underprepared on nutrition guidelines

A study published in the Journal of the American Osteopathic Association found that nearly 55% of medical students are confident in their ability to counsel patients on nutritional recommendations, despite half failing a nutrition quiz. The study highlights a gap between nutritional knowledge and attitudes among future physicians.

Approximately 1 in 9 US men infected with oral HPV

A study by the American College of Physicians found that almost 11 million US men have oral human papillomavirus (HPV) infection, with a high prevalence among men with multiple lifetime oral sex partners and those who report having sex with men. HPV causes various cancers, including oropharyngeal squamous cell carcinoma, which dispropo...

A cautionary tale

Researchers at LMU's Gene Center found that human cells use a different mechanism to recognize misplaced DNA than mouse cells. The inflammasome complex is activated via the cGAS-STING recognition mechanism, triggering both an antiviral response and a classical inflammatory reaction.

An epigenetic key to unlock behavior change

A new study sheds light on the molecular mechanism that shapes behavior in fruit flies, revealing a causal link between epigenetics and genetics. Researchers found that epigenetic marks interact with genes to regulate differences in feeding behaviors.

Liquid metal brings soft robotics a step closer

Researchers at University of Sussex and Swansea University have created a way to morph liquid metal into physical shapes, opening up new possibilities in soft robotics and shape-changing displays. The invention uses electrical charges to program the liquid metal, allowing it to dynamically change shape and form complex geometries.

Cancer relapse linked to body's own immune system

A new study reveals that cancer cells can use the body's own immune system to wake themselves up and fuel their growth after treatment, leading to relapse. Researchers found that immunotherapies targeting this response could delay or prevent cancer return in mice, suggesting a promising approach for patients at risk of relapse.
