Should there be an upper age limit for lung transplants?

Experts weigh the pros and cons of an upper age limit for lung transplants, citing concerns over organ shortage and quality of life. Some argue that setting a hard age limit ignores biological variability and comorbidities, while others suggest increasing donor supply and utilization could solve the issue.

Reimagining heart transplant allocation worldwide

A new global allocation system is being proposed to address inequities in organ allocation for heart transplants. The proposal aims to reduce disparities and ensure no viable donor heart goes unused globally.

How the adult brain learns when to persist and when to change

New research identifies Smoothened as a regulator of dopamine-acetylcholine timing, influencing learning, motivation, and behavioral flexibility in adulthood. The study found that animals lacking Smoothened learned motor tasks more quickly but were less sensitive to changes in effort or reward timing.

Pacific annular warming elevates the 2026/27 El Niño prediction

Researchers have forecasted a super El Niño event toward the end of 2026, driven by a rare and extreme surface annular warming pattern in the tropical Pacific. The current heat content buildup alone would generate a moderate El Niño, but adding the influence of annular warming intensifies it into the super category.

Quantum dots for light technologies of the future

Researchers at LMU Munich have overcome two major hurdles in working with perovskite quantum dots: stabilization in solution and precise control of their growth. By using Gemini ligands, they created stable quantum dots that can disperse in polar solvents and exhibit high photoluminescence quantum yields.

Why do some people act on climate change while others stay silent?

The study found three distinct types of climate supporters: activists, anxious individuals who want to help but struggle with motivation, and hierarchy enhancers who use radical tactics for competitive reasons. Understanding these differences can inform effective communication strategies for climate movements.

Cardiac CT scans see the future: Visualizing "invisible" heart risks

Researchers at Kumamoto University discovered that combining cardiac Computed Tomography (CT) scan markers can identify patients at highest risk for future heart failure and death. The 'delayed phase' scan detects localized scarring and subtle damage throughout the heart muscle, providing a synergistic view of heart health.

Playing with your dog creates a stronger bond

A Linköping University study shows that playing with dogs for just a few minutes a day can significantly improve the emotional bond between owners and their pets. Dog training did not have the same effect, suggesting that playtime is crucial for building strong relationships.

Study of Ukrainian war amputees finds most recover from pain and trauma

A longitudinal study of 156 Ukrainian amputees found that most experience steady improvements in pain, anxiety, and depression over time. The study revealed distinct patterns of post-amputation pain, with phantom limb pain linked to psychological distress and residual limb pain linked to depression.

Garmin GPSMAP 67i with inReach provides rugged GNSS navigation, satellite messaging, and SOS for backcountry geology and climate field teams.

Asphalt is everywhere; but is it bad for our health?

Researchers have found that asphalt releases volatile organic compounds (VOCs) into the air, which can cause respiratory problems and even lung cancer. As pavement ages, these VOCs become more toxic and can lead to neurological damage. Scientists are working on developing less-toxic asphalt formulations using algae.

Getting the jump on evolution: Cane toads adapt at speed

A new study found substantial changes in cane toad body size and shape have developed rapidly in response to environmental pressures on Ishigaki Island in Japan. The toads there are heavier and larger than those in Australia, with wider heads and shorter arms and longer legs.
