NASA’s Roman Telescope to Carry 1.35 Million Names to Deep Space

On July 27, technicians at NASA’s Kennedy Space Center in Florida installed a memory card containing 1,350,144 names as part of a commemorative plaque on the Nancy Grace Roman Space Telescope. The names were submitted by people globally, including astronauts from Artemis II and Artemis III. The memory card will travel with the Roman observatory […]

Experts say blood pressure guidelines are missing half the equation

A new report suggests that blood pressure may be controlled more effectively by increasing potassium while also cutting sodium. Potassium-rich foods can help balance sodium’s effects, but most people consume far less potassium than recommended.

New process turns plastic waste into hydrogen fuel while trapping the carbon

A new chemical process can transform three of the most common plastics into high-purity hydrogen without sorting them first. The technique operates at much lower temperatures than traditional gasification and captures most of the plastic’s carbon in solid or liquid forms instead of releasing it as carbon dioxide.

A 42-year-old childhood obesity theory may be wrong

New research challenges the decades-old idea that children experience an “adiposity rebound” when their BMI begins rising around age 6. Although BMI returns to earlier levels, a more reliable measure showed that body fat does not rebound at all. The increase appears to come from growing muscle and lean tissue as children prepare for later growth. Researchers say this normal process has been mistakenly treated as an obesity warning sign for 42 years.

Black holes may spit out nearly as much matter as they swallow

A black hole observed during a dramatic 2023 eruption did not simply devour gas from its nearby companion star. It also expelled large amounts of material through powerful jets and winds, even after the outburst had nearly faded. The results suggest black holes may continue reshaping their surroundings long after their brightest fireworks end.

AI can tell if your brain is aging faster than you are

A person’s sleeping brain may reveal warning signs of dementia long before memory problems begin. Researchers used machine learning to analyze EEG recordings from about 7,000 adults and found that an older-than-expected “brain age” was tied to a sharply higher dementia risk. Every additional 10 years of brain aging raised that risk by nearly 40%.

This new alloy is up to 10 times stronger than steel and surprisingly flexible

Engineers have transformed a notoriously brittle cobalt-aluminum compound into a material that is both extremely strong and capable of bending without breaking. Their nanoscale design produced a yield strength about six to 10 times greater than high-strength structural steel while sustaining substantial deformation at room temperature. The approach could enable tougher turbine blades and higher-performance engines.

A strange quantum rule caps electrical resistance

Physicists have uncovered a surprising limit to electrical resistance caused by particles colliding. Using ultracold potassium atoms trapped in a grid of light, researchers created a highly controlled stand-in for electrons moving through a solid. As collisions became more frequent and intense, resistance initially rose, but eventually hit a ceiling and stopped increasing.

Scientists discover how obesity may fuel Alzheimer’s disease

Researchers have uncovered a possible biological pathway connecting obesity to Alzheimer’s disease. Obesity appears to raise levels of certain fat molecules that can travel to the brain, disrupt its immune defenses, and promote harmful amyloid buildup. Correcting this fat imbalance improved memory and brain function in Alzheimer’s models.

Keeping a regular daily schedule may help reduce pain and depression, especially among older adults with insomnia. Researchers found that consistent times for waking, eating, socializing, and sleeping were linked to better well-being regardless of sleep quality. These routines may strengthen the body’s internal clock and limit the disruptive effects of “social jet lag.”
