A newly identified fossil ape from northern Egypt is reshaping ideas about where the ancestors of modern apes first emerged。 Analyses place it closer to living apes than any known East African species of the same age, pointing to North Africa and the Middle East as a possible birthplace and crossroads for the ape lineage that eventually produced gi
OP here: I created this visualization tool as the byproduct of a supply chain class I taught at Columbia。 The pedagogical exercise grew into a full blown visualization and paper about global oil trade。The model: The mechanics are the same as the financial network
A newly discovered turning point in the Sun’s 11-year cycle could allow scientists to predict future solar activity years earlier than before。 At this “switch-off” point, the most violent space weather abruptly ends, and the remaining number of sunspots offers clues about the next cycle’s strength。 Early projections suggest Solar Cycle 26 may be mo
The longevity-linked APOE2 gene appears to protect brain cells by reducing DNA damage and helping neurons recover from stress。 The finding could open a new path toward treatments that mimic APOE2’s defenses in people at higher genetic risk for Alzheimer’s
Researchers found that specific brain circuits help decide which jobs bees perform as they age。 When those circuits were switched off, older worker bees began caring for the queen again instead of carrying out their normal later-life duties。 The findings reveal that a bee colony’s complex division of labor may be guided by neural switches hidden in
Researchers in the Gulf of California have documented a dramatic orca behavior never described before。 In two separate encounters, one orca gripped a dead sunfish by the fin while another charged into it at high speed, blasting the carcass into thousands of pieces
Astronomers have found the first confirmed atmosphere around a rocky planet in another star’s habitable zone。 The planet, LHS 1140 b, revealed its atmosphere through helium slowly leaking into space。 Located 48 light-years away, the world may have preserved its atmosphere for billions of years, making it a promising target in the search for potenti
A giant planet had been hiding inside one of astronomy’s most closely studied planetary systems, concealed by a bright disk of cosmic dust。 Webb revealed Beta Pictoris d through atmospheric traces of carbon monoxide, water vapor, and methane, showcasing a promising new method for finding elusive exoplanets
NASA is preparing for future astronaut landings on the Moon with an unusually ambitious orbital rehearsal。 During Artemis III in 2027, Orion astronauts will rendezvous and dock separately with prototype lunar landers from Blue Origin and SpaceX, allowing crews and ground teams to test the complex maneuvers needed for later missions
