Researchers propose that a long-overlooked neutrino may have influenced the early universe in a way that allowed matter to survive the Big Bang. The process could have produced gravitational-wave signals that future detectors might identify.

Scientists built a molecular motor inspired by Archimedes’ screw that can rotate in either direction when powered by electricity. Its motion can increase electrical conductivity by up to 100 times, suggesting a possible route toward new molecular-scale electronic components.

A 17 to 18 million-year-old ape fossil found in Egypt is challenging the assumption that modern apes and human ancestors first evolved in East Africa. The discovery points instead to North Africa and the Middle East as possible early centers of ape evolution.

Researchers propose that a long-overlooked neutrino may have influenced the early universe in a way that allowed matter to survive the Big Bang. The process could have produced gravitational-wave signals that future detectors might identify.
The key shift is from treating the particle as an obscure theoretical possibility to testing

A detection could help explain why matter, and therefore galaxies and life, exists at all.
Summary
Scientists built a molecular motor inspired by Archimedes’ screw that can rotate in either direction when powered by electricity. Its motion can increase electrical conductivity by up to 100 times, suggesting a possible route toward new molecular-scale electronic components.
The key advance is the combination of reversible molecular motion and a large, measurable change

A mechanically active molecule that also functions as an electrical switch could expand the design options for electronics at the smallest scale.
Summary
A 17 to 18 million-year-old ape fossil found in Egypt is challenging the assumption that modern apes and human ancestors first evolved in East Africa. The discovery points instead to North Africa and the Middle East as possible early centers of ape evolution.
The fossil shifts the geographic focus of ape evolution beyond East Africa, but it does

NASA is seeking proposals from commercial space companies to raise Hubble's orbit and extend the telescope's operational life. Without an orbital boost, atmospheric drag could bring Hubble down in the early to mid-2030s, though it is not in immediate danger.

November brings three meteor showers, including meteors bright enough to remain visible from urban areas. The month also offers the year's best opportunity to spot Uranus.

Research on the Great Barrier Reef found that nearly 75% of observed crown-of-thorns starfish feeding events left some living coral tissue behind. By consuming fast-growing dominant corals, the starfish may create space for slower-growing species and increase reef diversity when their numbers remain controlled.

November brings three meteor showers, including meteors bright enough to remain visible from urban areas. The month also offers the year's best opportunity to spot Uranus.
The key advantage is timing: several separate showers create repeated viewing opportunities, while Uranus reaches

November offers accessible opportunities for both casual skywatchers and more serious observers without requiring travel far from the city.
Summary
Research on the Great Barrier Reef found that nearly 75% of observed crown-of-thorns starfish feeding events left some living coral tissue behind. By consuming fast-growing dominant corals, the starfish may create space for slower-growing species and increase reef diversity when their numbers remain controlled.
The finding changes the management question from eliminating crown-of-thorns starfish to controlling damaging population outbreaks

Reef conservation may need to manage a predator as part of the ecosystem rather than treat it as an unqualified threat.
