Tesla begins offering extended warranty coverage for the Cybertruck PCS, and begins reimbursing owners who have had to previously pay for replacements.

Anthropic found three cases where Claude models escaped test sandboxes and compromised real systems, exposing why AI evaluation infrastructure needs production-grade security.

Reviewing the ColdCard situation, FOMC, US rates, Japanese yen, and the US economy.

Mais de 20 anos no poder, indo para o quarto mandato, principal adversário cassado e preso por um crime imaginário, total controle das instituições. Falta o quê? Dar um brilho na imagem. Falta um podcast bonitinho, planejado, com boa iluminação e fotografia…

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…

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…

Scientists traced a mysterious surge of low-energy gamma rays from zinc-70 to magnetic changes occurring inside its nucleus. The breakthrough could improve models of how stars, supernovae, and neutron star mergers create heavy elements.

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…

Scientists have built the first all-optical photonic time crystal, allowing them to reshape the behavior of terahertz light at extraordinary speeds. The breakthrough could open the door to ultrafast computing, smarter communication systems, advanced imaging…

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…

A gene involved in the brain’s overnight cleaning system may change how strongly poor sleep affects Alzheimer’s-related brain changes. The findings point toward more personalized prevention strategies based on both genetics and sleep habits.

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…

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.

Modern humans carry DNA from two mysterious extinct lineages in addition to Neanderthals and Denisovans. Their hidden genetic legacy shows that our evolutionary past was shaped by repeated mixing among many different human groups.

A surprisingly simple change could make sodium-ion batteries far more powerful while opening the door to turning seawater into drinking water. Researchers at the University of Surrey found that sodium vanadium oxide performs much better when its naturally…

Scientists have identified an immune response that may explain why statins cause muscle pain, weakness, and exercise intolerance in some people. The finding could eventually lead to treatments that protect muscles while preserving the drugs’ lifesaving cardiovascular…

A daily avocado may help lower heart disease risk in adults with obesity by reducing the number of LDL particles circulating in the blood. After six months, participants who ate an avocado each day experienced a decline associated with an estimated 4% reduction…

Ant parenting may have evolved from the same brain systems that once controlled hunger. Researchers found that two chemical signals push clonal raider ants toward either caring for larvae or leaving to forage, with the balance changing as the ants grow older.…

Consumir vídeos de 60 segundos não é estudo. É entretenimento fantasiado de produtividade.

A maestria intelectual não se constrói em pílulas diárias, mas em blocos ininterruptos de foco profundo.

Sem tempo de reflexão, não há síntese real.
