Do our genes determine what we eat? Study could pave the way to personalized nutrition guidance based on our taste perception
Preliminary findings from a new study involving more than 6,000 adults found that taste-related genes may play a role in determining food choices and could, in turn, influence cardiometabolic health. It is one of the first studies to examine how the genetics tied to perception for all five tastes — sweet, salt, sour, bitter, and […]
Patients With HIV at Higher Risk for COVID Breakthrough Infections
Patients with HIV who were fully vaccinated against COVID-19 were more likely to develop a breakthrough infection, according to a study of the Corona-Infectious-Virus Epidemiology Team (CIVET)-II cohort. Among nearly 114,000 fully vaccinated patients, those with HIV had a 28% higher risk of breakthrough infection compared with those without HIV (adjusted hazard ratio [aHR] 1.28, […]
KRAS Inhibitor Shrinks Tumors in Over 40% of NSCLC Patients
CHICAGO — More than 40% of patients with KRAS G12C-mutated non-small cell lung cancer (NSCLC) responded to treatment with adagrasib, findings from a phase II trial showed. Among 112 evaluable patients in the KRYSTAL-1 study, all of whom were previously treated, the confirmed objective response rate (ORR) was 42.9% with the investigational KRAS G12C inhibitor, […]
Particulate Matter Size Tied to Stroke Mortality
Hospitalized stroke patients living in areas with greater air pollution were more likely to die from their stroke, but the size of ambient particulate matter (PM) and duration of exposure both played a role in the level of risk, an observational study from China indicated. Effect sizes were greatest for smaller-sized particles (PM1) and with […]
Low-cost gel film can pluck drinking water from desert air
More than a third of the world’s population lives in drylands, areas that experience significant water shortages. Scientists and engineers at The University of Texas at Austin have developed a solution that could help people in these areas access clean drinking water. The team developed a low-cost gel film made of abundant materials that can […]
‘Traffic calming’ boosts breeding on coral reefs
Coral reef fish breed more successfully if motorboat noise is reduced, new research shows. Scientists introduced “traffic calming” on three reefs for an entire breeding season — cutting the number of boats within 100m, and reducing the speed of those within that distance. They then tracked the breeding of fish called spiny chromis — and […]
New weight-loss intervention targets instinctive desire to eat
People who are highly responsive to food lost more weight and, importantly, were more successful at keeping the pounds off using a new alternative weight-loss intervention that targets improving a person’s response to internal hunger cues and their ability to resist food, reported a team led by University of California San Diego experts in the […]
Mental Health Issues Common, Often Overlooked in Prostate Cancer
NEW ORLEANS — More than a third of men with newly diagnosed prostate cancer had at least one mental health issue, which had a strong association with prior psychological wellbeing, a prospective cohort study showed. Almost 30% of the men had a fear of cancer recurrence or poor prognosis, and 22% met diagnostic criteria for […]
Scientists provide more than 50K camera trap images for massive study on Amazon wildlife
WCS scientists working in the vast Amazon Basin have contributed more than 57,000 camera trap images for a new study published in the journal Ecology by an international team of 120 research institutions. The study consists of 120,000-plus images taken in eight countries, representing the largest photo database to date of the Amazon’s staggering array […]
Humans may have evolved to show signs of stress to evoke support from others: Showing signs of stress could make us more likeable and prompt others to act more positively towards us
Showing signs of stress could make us more likeable and prompt others to act more positively towards us, according to a new study by scientists at Nottingham Trent University and the University of Portsmouth. Researchers examined the paradox of stress behaviour, namely why, as in other primates, humans show signs of stress — such as […]
