Researchers found that excess RNA, including messenger RNA, can directly damage mitochondria, the structures that produce cellular energy. The effect does not require an immune response and may help explain some damage caused by viral infections and aging-related diseases.

Scientists have identified the buried Silverpit Crater as the result of a roughly 160-meter asteroid impact 43 to 46 million years ago. The collision sent rock and water 1.5 kilometers into the atmosphere and generated a tsunami more than 100 meters high.

Researchers reprogrammed blood cells from an 80-year-old into neural stem cells with molecular age markers below 20. The laboratory technique could help study cellular aging and diseases such as Alzheimer's, but it does not yet demonstrate whole-body rejuvenation.

Researchers found that excess RNA, including messenger RNA, can directly damage mitochondria, the structures that produce cellular energy. The effect does not require an immune response and may help explain some damage caused by viral infections and aging-related diseases.
The key shift is that RNA itself can impair mitochondria rather than merely activating immune

Ancient impact sites reveal how quickly asteroid strikes can trigger catastrophic coastal hazards.
Summary
Researchers reprogrammed blood cells from an 80-year-old into neural stem cells with molecular age markers below 20. The laboratory technique could help study cellular aging and diseases such as Alzheimer's, but it does not yet demonstrate whole-body rejuvenation.
The decisive advance is the creation of younger neural stem cells from aged human blood,

Scientists corrected the date of a famous train disruption attributed to a solar storm, placing it in 1848 rather than 1841. The revision strengthens the early historical record of space weather and connects the episode to modern risks for power grids, satellites, and communications.
8:35 AMScienceDaily
A study of 13 astronauts found that their hearts adapted to months of weightlessness and performed adequately under simulated Martian gravity. Regular exercise appeared to support cardiovascular function during spaceflight.
7:59 AMScienceDaily
A 3-D reconstruction of apartment-tower failures during Venezuela's June earthquakes shows that structural weaknesses, not earthquake intensity alone, contributed to the collapses. The analysis examines how those flaws left multiple buildings unable to withstand the shaking.

NASA's Perseverance rover has driven farther on another world than any previous vehicle, surpassing Opportunity's 28.06-mile record in about five and a half years. Its autonomous driving system is now helping it investigate some of Mars's oldest rocks for evidence of ancient habitable environments.

The article argues that a Type 1 error, or a false positive finding, can occur even when researchers follow sound methods and standards. Replication is therefore necessary to distinguish genuine effects from results produced by chance.

Scientists corrected the date of a famous train disruption attributed to a solar storm, placing it in 1848 rather than 1841. The revision strengthens the early historical record of space weather and connects the episode to modern risks for power grids, satellites, and communications.
The date correction matters because reliable historical records help establish how often extreme solar activity

Cardiovascular resilience appears manageable for Mars missions, but larger and longer studies must validate the result.
Summary
A 3-D reconstruction of apartment-tower failures during Venezuela's June earthquakes shows that structural weaknesses, not earthquake intensity alone, contributed to the collapses. The analysis examines how those flaws left multiple buildings unable to withstand the shaking.
The decisive finding is that construction and design vulnerabilities amplified the earthquakes' effects. That shifts
