Nature images on Instagram can boost well-being and positive emotions, researchers say

Imagine you are a security guard in one of those casino heist movies where your ability to recognize an emerging crime will depend on whether you notice a subtle change on one of the many security monitors arrayed on your desk. That's a challenge of visual working memory.

When ultra-runners lace up for races that stretch hundreds of miles and days, they're not merely testing their mental grit and muscle strength—they're probing the limits of human biology. Reporting in Current Biology, researchers found that even the most extreme athletes cannot surpass an average "metabolic ceiling" of 2.5 times their basal metabolic rate (BMR) in energy expenditure.

Scientists at University of California San Diego have developed a new approach to destroying cancer stem cells—hard-to-find cells that help cancers spread, come back after treatment and resist therapy. The new approach, which the researchers tested in colon cancer, leveraged artificial intelligence (AI) to identify treatments that can reprogram cancer stem cells, ultimately triggering them to self-destruct.

Current NHS policies designed to improve care for people taking multiple medicines may not be effective, according to new research.

Pre-eclampsia is one of the most serious complications in pregnancy, affecting millions of women and newborns worldwide. Despite intensive research, it has remained unclear what processes in the placenta lead to the disease. Now, a research team led by the Medical University of Vienna has discovered a previously unknown mechanism that plays a decisive role in the development of pre-eclampsia. The results, published in the journal Nature Communications, could open up new possibilities for diagnosis and treatment.

Research led by Friedrich-Alexander-Universität Erlangen–Nürnberg provides evidence that teclistamab may offer therapeutic benefit for patients with severe forms of treatment-resistant autoimmune diseases.

The oral targeted therapy sevabertinib led to tumor reduction and manageable side effects in patients with HER2-mutant non-small cell lung cancer (NSCLC), according to data from a trial led by researchers at The University of Texas MD Anderson Cancer Center.

Working with an international team of collaborators, scientists at Columbia University have found a way to shift the balance of a type of white blood cell inside a stomach tumor, causing the immune system to recognize and attack the cancer instead of ignoring it. The work, published in the August issue of Cancer Cell, also sheds light on immune functions that may drive many other diseases.

It's a tactic many parents know well: "Eat two bites of broccoli, and then you can have dessert."

An opportunistic bacterial infection that causes deadly diarrhea is more likely to kill white patients than Black or Hispanic people, a new study presented at IDWeek says.

Many eye banks won't accept corneas from donors with diabetes, concerned they might be harder to prepare for transplant surgery or are more likely to fail.

The shingles vaccine does more than just protect middle-aged folks and seniors against maddening rashes, a new study says.

Babies can be safely administered antibody protection against respiratory syncytial virus (RSV) after birth even if their moms had RSV vaccination while pregnant, a new study says.

Rutgers New Jersey Medical School-led researchers have identified a striking rise in pickleball-related eye injuries among players visiting emergency departments across the United States. Using two decades of national surveillance data, the team found an accelerating pattern of trauma tied to the sport's rapid expansion.

Mental health distress is rising among America's LGBTQ+ teenagers and young adults as they've increasingly become targets of discrimination and cruelty, a new report says.

By the time patients start seeking care for multiple sclerosis (MS), the disease has already been damaging their brains for years. But until recently, scientists didn't understand which brain cells were being targeted or when the injury began.

University of North Carolina at Charlotte's School of Nursing, collaborating with Harvard's Human Flourishing Program, reports that adolescents who report transformative religious or spiritual experiences show both greater volunteering and voting in early adulthood alongside elevated loneliness and PTSD.

Every year, thousands of families sit in hospital rooms hearing words no one wants to hear: "We have done everything we can." What happens next, whether doctors stay engaged or step away, can transform one of life's most difficult moments for patients and their families.
