MIT scientists turn immune cells into cancer killers inside the body

MIT scientists have developed nanoparticles that reprogram immune cells directly inside the body to attack cancer and harmful immune cells, eliminating tumors and reversing liver damage in mouse experiments. The breakthrough could make powerful immune therapies dramatically simpler and less expensive while opening new possibilities for treating cancer and autoimmune diseases.

A nuclear blast could save Earth from an asteroid, but there's a catch

A nuclear explosion might save Earth from a deadly asteroid, but new research suggests that hitting the wrong side could make the difference between success and disaster. Scientists found that an asteroid's irregular shape can dramatically affect how it responds to an X-ray blast, with deflection effectiveness varying nearly fivefold depending on the angle.

Low testosterone linked to 18% higher risk of dying from cancer

A major international study tracking more than 26,000 men found that very low testosterone levels were associated with an 18% higher risk of dying from cancer later in life. Surprisingly, testosterone itself showed no clear link to prostate cancer, although two other sex hormones did. Researchers believe low testosterone could be an important early warning sign of future health risks, particularly when levels fall below 8.6 nmol/L.

Ancient Siberian tomb reveals surprising secrets of cannabis use 2,800 years ago

Scientists investigating a 2,800-year-old Siberian tomb discovered roughly 1,000 cannabis seeds and chemical evidence suggesting ancient Scythians used the plant for its intoxicating effects. The remarkable find, surrounded by evidence of elaborate burial rituals and animal sacrifices, offers the oldest directly dated archaeological evidence of psychoactive cannabis use.

Scientists discover hidden brain changes linked to common sleep disorders

Scientists have discovered that sleep disorders are associated with structural changes in brain regions that control attention, decision-making, and emotions, potentially explaining why disrupted sleep can affect everyday thinking and behavior. The findings, drawn from 57 brain imaging studies, reveal both shared and disorder-specific patterns that could lead to more targeted treatments.

Scientists squeeze record-breaking X-ray power into an incredibly tiny spot

Scientists have created record-breaking X-ray flashes lasting just 300 attoseconds, concentrating enormous power into an incredibly tiny spot. The breakthrough could unlock a new way to observe electrons in action and potentially control the ultrafast processes that drive chemical reactions.

Stronger flu shot linked to nearly 55% lower Alzheimer's risk

A surprising new study suggests that a stronger flu shot could offer older adults significantly greater protection against Alzheimer's disease. Researchers at UTHealth Houston analyzed nearly 200,000 adults ages 65 and older and found that those who received a high-dose influenza vaccine had a nearly 55% lower risk of developing Alzheimer's, compared with a 40% reduction previously associated with the standard-dose vaccine.

Why the tropics lose the most birds when cities expand

Tropical ecosystems are famous for their teeming, exuberant diversity. In fact, the dramatic increase in biodiversity from the poles to the tropics—known as the latitudinal diversity gradient—is pervasive across branches of the tree of life, and fossil evidence suggests it has existed for millennia.

Scientists discover a hidden warning sign of cannabis addiction

A study of more than 17,700 US adults found that people who use cannabis in multiple forms have dramatically higher rates of daily consumption and addiction symptoms than those who stick primarily to one method. Nearly 67% of those who used almost every form met criteria for cannabis use disorder, compared with just 15% of people who mainly consumed edibles.

Mysterious gas leaks suggest Mars may still be volcanically alive

Mysterious gas emissions and fresh volcanic fissures suggest that Mars may not be geologically dead after all, with hot magma potentially still active deep underground. The discovery could point to hidden pockets of warmth and chemical energy capable of supporting microbial life beneath the Red Planet’s surface.

A hidden limit of space and time could unlock electronics 100,000 times faster

Scientists have discovered a surprising quantum limit that prevents electrons from being tracked with unlimited precision in both space and time. The breakthrough could pave the way for manipulating chemical reactions and developing electronics hundreds of thousands of times faster than today's technology.

Personalized savings reminders can help boost retirement savings

Private retirement savings are an increasingly important topic in public debate. One popular idea is to phrase savings reminders in one of two ways: either you emphasize what someone stands to lose if they don't save, or you emphasize what they stand to gain if they do. To date, research into which of the two reminder messages is more effective in terms of influencing people's efforts to save has produced conflicting results.
