Dialog / Rethinking climate change: Natural variability, solar forcing, model uncertainties, and policy implications
Current global climate models (GCMs) support with high confidence the view that rising greenhouse gases and other anthropogenic forcings account for nearly all observed global surface warming—slightly above 1 °C—since ...
Phys.org / Sophie Adenot, the second French woman to fly to space
When she was growing up, Sophie Adenot plastered her childhood bedroom with posters of rockets launching from Cape Canaveral.
Medical Xpress / Why you hardly notice your blind spot: New tests pit three theories of consciousness
Although humans' visual perception of the world appears complete, our eyes contain a visual blind spot where the optic nerve connects to the retina. Scientists are still uncertain whether the brain fully compensates for the ...
Phys.org / Football-sized fossil creature may have been one of the first land animals to eat plants
Life on Earth started in the oceans. Sometime around 475 million years ago, plants began making their way from the water onto the land, and it took another 100 million years for the first animals with backbones to join them. ...
Phys.org / Failed supernova provides clearest view yet of a star collapsing into a black hole
Astronomers have watched a dying star fail to explode as a supernova, instead collapsing into a black hole. The remarkable sighting is the most complete observational record ever made of a star's transformation into a black ...
Tech Xplore / Organic molecule stores solar energy for years, then releases it as heat on demand
When the sun goes down, solar panels stop working. This is the fundamental hurdle of renewable energy: how to save the sun's power for a rainy day—or a cold night. Chemists at UC Santa Barbara have developed a solution ...
Medical Xpress / Alert for blood monitor sold by Walmart, Publix, others after injuries and death
After more than 11 years of injuries and a death, the manufacturer of blood glucose monitors has issued a correction to the instructions directing actions when the glucose might be dangerously high.
Phys.org / Nature's 'engine is grinding to a halt' as climate change gains pace, says study
Many ecologists hypothesize that, as global warming accelerates, change in nature must speed up. They assume that as temperatures rise and climatic zones shift, species will face local extinction and colonize new habitats ...
Phys.org / Scientists uncover Iron Age origins of Vietnamese tooth blackening practices
Not everyone wants their teeth to be white and gleaming. Tooth blackening is a recognized part of modern Vietnamese culture, and a recent discovery hints that the roots of this practice may stretch all the way back to the ...
Phys.org / Experiment relies on pulsars to probe dark matter waves
Dark matter is a type of matter that is predicted to make up most of the matter in the universe, yet it is very difficult to detect using conventional experimental techniques, as it does not emit, absorb, or reflect light. ...
Tech Xplore / Redesigned electrolyte helps lithium-metal batteries safely reach full charge in 15 minutes
Lithium-metal batteries (LMBs) are rechargeable batteries that contain an anode (i.e., the electrode through which current flows and a loss of electrons occurs) made of lithium metal. Compared to conventional lithium-ion ...
Medical Xpress / In Cordoba, the grass pollen season has grown longer over the last 23 years
A study analyzes the relationship between pollen and meteorological data spanning 23 years, verifying how the wind impacts each phase of the pollen season differently, thereby helping to manage and prevent allergy seasons. ...
