Scientists warn that global temperatures are nearing an overshoot of the 1.5°C climate target as COP31 begins. They say governments must commit to removing carbon dioxide from the atmosphere if temperatures are to return to safer levels.

Researchers found that the stickiness of marine snow strongly affects how much carbon sinks into the deep ocean. Gooier particles resist bacterial breakdown and can carry more than six times as much carbon downward as less cohesive particles.

New research suggests that an X-ray-producing nuclear blast could deflect a dangerous asteroid, but the outcome depends heavily on where the blast strikes. An asteroid's irregular shape can cause deflection effectiveness to vary by nearly fivefold with the angle of impact.

Scientists warn that global temperatures are nearing an overshoot of the 1.5°C climate target as COP31 begins. They say governments must commit to removing carbon dioxide from the atmosphere if temperatures are to return to safer levels.
The central shift is from preventing 1.5°C warming to managing a likely breach and planning

Overshooting 1.5°C would make climate policy depend on both rapid emissions cuts and the uncertain expansion of carbon removal.
Summary
Researchers found that the stickiness of marine snow strongly affects how much carbon sinks into the deep ocean. Gooier particles resist bacterial breakdown and can carry more than six times as much carbon downward as less cohesive particles.
Particle texture is now a potentially important climate variable, not just a biological detail. If

The ocean's capacity to store carbon depends partly on the physical properties of sinking organic matter.
Summary
New research suggests that an X-ray-producing nuclear blast could deflect a dangerous asteroid, but the outcome depends heavily on where the blast strikes. An asteroid's irregular shape can cause deflection effectiveness to vary by nearly fivefold with the angle of impact.
The decisive fact is that nuclear deflection is not a simple matter of delivering enough

Planetary defense may have a powerful option, but its success depends on reconnaissance as much as explosive force.
A curated list of other prominent stories from this day.
Researchers identified Laimosemion laranja, a brightly patterned killifish less than three centimeters long, in only three small forest pools in the Brazilian Amazon. Mining, deforestation, pollution, and development threaten the narrow habitat on which the species appears to depend.

Fossils from Colombia reveal a highly diverse marine ecosystem in which giant reptiles, sharks, and other predators thrived as older evolutionary groups declined and newer ones emerged. Researchers describe this pattern as a "Biotic Inflection," a major biological transition that did not coincide with a mass extinction.

Researchers have identified a theoretical process called gravitational reconnection within Einstein's equations. In their model, structures in gravitational fields can break apart and reconnect, transferring energy into matter.

Researchers found about 1,000 cannabis seeds and chemical evidence of intoxication in a 2,800-year-old Siberian tomb. The burial also contained signs of elaborate rituals and animal sacrifice, providing the oldest directly dated archaeological evidence of psychoactive cannabis use.

Researchers identified Laimosemion laranja, a brightly patterned killifish less than three centimeters long, in only three small forest pools in the Brazilian Amazon. Mining, deforestation, pollution, and development threaten the narrow habitat on which the species appears to depend.
The discovery arrives with an immediate conservation problem: the fish may have an extremely small

Species-rich habitats can contain organisms already at high risk before scientists have time to study or protect them.
Summary
Fossils from Colombia reveal a highly diverse marine ecosystem in which giant reptiles, sharks, and other predators thrived as older evolutionary groups declined and newer ones emerged. Researchers describe this pattern as a "Biotic Inflection," a major biological transition that did not coincide with a mass extinction.
The finding challenges the assumption that major evolutionary turnovers require catastrophic extinction events. It suggests

Evolutionary change may be more often driven by complex ecological turnover than by sudden global catastrophe.
Summary
Researchers have identified a theoretical process called gravitational reconnection within Einstein's equations. In their model, structures in gravitational fields can break apart and reconnect, transferring energy into matter.
The result expands the range of behavior permitted by general relativity, but it remains a

A new solution to general relativity could point to previously unrecognized ways that gravity powers energetic cosmic phenomena.
Summary
Researchers found about 1,000 cannabis seeds and chemical evidence of intoxication in a 2,800-year-old Siberian tomb. The burial also contained signs of elaborate rituals and animal sacrifice, providing the oldest directly dated archaeological evidence of psychoactive cannabis use.
The find moves evidence of deliberate cannabis intoxication from inference toward direct archaeological proof. It
