Sun fires 4 strong solar flares as NOAA tracks X8.1 blast and possible Earth brush-by

Soarele emite 4 erupții solare puternice, în timp ce NOAA monitorizează explozia X8.1 și posibila atingere a Pământului

NOAA reported a major X8.1 solar flare from active region 4366 late on February 1, with minor solar effects possible around February 5. NASA recorded four X-class flares between February 1 and early February 2. U.S. forecasters raised the risk of radio blackouts and a minor solar radiation storm through February 4. Most ejected material is expected to miss Earth, with only marginal impacts likely.

NASA interrupts TESS survey to track interstellar comet 3I/ATLAS as SPHEREx spots stronger gases

NASA întrerupe sondajul TESS pentru a urmări cometa interstelară 3I/ATLAS, în timp ce SPHEREx detectează gaze mai puternice

NASA redirected its TESS satellite from its regular survey to observe interstellar comet 3I/ATLAS, collecting continuous brightness data from January 15–22. New SPHEREx measurements show the comet’s gas emissions surged twentyfold after its October perihelion, with new signs of cyanide and organic gases. NASA says 3I/ATLAS poses no threat to Earth and will remain visible with small telescopes through spring.

Cometa 3I/ATLAS pare brusc „pe deplin activ” — iar astronomii spun că fereastra de observare se închide

NASA’s SPHEREx telescope recorded a surge in gas and dust from interstellar comet 3I/ATLAS after its close solar pass. Scientists confirm it as only the third known interstellar object in the solar system. The comet reaches opposition on January 22, improving ground-based viewing. Data show water vapor emissions about 20 times higher than previous readings.

Cometa 3I/ATLAS Astăzi (15 Noiembrie 2025): Actualizare Traiectorie ESA, Revenirea Cozii, Semnale Radio și Explicații pentru Afirmațiile despre Extratereștri

New images and refined orbital data released November 15 show interstellar comet 3I/ATLAS survived its close approach to the Sun intact and remains active. Astronomers confirm its hyperbolic trajectory means it will not return after leaving the Solar System. Debate continues over its unusual gas jets, with some experts suggesting natural causes and others raising the possibility of artificial origins.

Revoluția ultravioletă: În interiorul mașinilor invizibile de 150 de milioane de dolari care modelează viitorul microcipurilor

ASML remains the sole supplier of EUV lithography machines, each costing $150–180 million and consuming over 1 megawatt. TSMC first used EUV at scale in 2019 for 7nm+ chips. Export controls bar ASML from selling EUV tools to China, though 2024 sales to China reached $7 billion, mainly from DUV equipment. Nikon and Canon have exited EUV development, focusing on other lithography technologies.

Revoluția enzimelor: Cum ingineria catalizatorilor naturali transformă medicina, alimentația și planeta

The global industrial enzyme market was valued at $9 billion in 2019 and is projected to reach $13.8 billion by 2027. In 2023, researchers reported AI-designed luciferase enzymes that can outperform natural ones. In 2022, UT Austin developed FAST-PETase, an enzyme variant that breaks down plastic waste in 24 hours. Late 2024 saw reports of a highly evolved CRISPR-Cas enzyme variant with greatly reduced off-target activity.

Întoarcerea timpului: Cum factorii Yamanaka resetează celulele îmbătrânite

Shinya Yamanaka identified OSKM factors in 2006 to reprogram mature cells into pluripotent stem cells. Since 2016, studies in mice and primates have shown partial OSK(M) reprogramming can extend lifespan, restore organ function, and reverse aging markers, with no major cancer observed. Human cell experiments reset age markers by decades. Safety and regulatory concerns remain, especially regarding cancer risk.

Google’s Willow quantum chip completed a task in under five minutes that would take a top supercomputer 10^25 years. Microsoft and UC Santa Barbara built the first topological qubits in an 8-qubit prototype. IBM surpassed 400 qubits on a chip, with a 1,121-qubit processor in development. China operates a 2,000-km quantum link between Beijing and Shanghai using satellites and fiber.
