Bill Gates shares his plan for fighting climate change.
Winds blowing across snow dunes on Antarctica's Ross Ice Shelf cause the massive ice slab's surface to vibrate, producing a near-constant set of seismic 'tones' scientists could potentially use to monitor changes in the ice shelf from afar, according to new research.
It is not enough that we try to limit further global warming – we must also do far more to ensure we survive it. That’s the message from a coalition of major global figures, including former UN head Ban Ki-moon and billionaire Bill Gates. The Global Commission on Adaptation, which is being launched today, says that the impact of global warming is already being felt much sooner and more powerfully than expected. To keep reducing global poverty and maintain economic growth, societies must do much more, much faster, to adapt.
Early life-forms on Earth may have been able to generate metabolic energy from sunlight using a purple-pigmented molecule called retinal that possibly predates the evolution of chlorophyll and photosynthesis. If retinal has evolved on other worlds, it could create a a distinctive biosignature as it absorbs green light in the same way that vegetation on Earth absorbs red and blue light.
Damage from Hurricane Michael is projected to cost billions of dollars, and experts say such storms will only get worse and more costly as climate change wreaks havoc on weather patterns. The Category 4 storm that pummeled Florida Gulf Coast communities this week, leaving more than a dozen people dead, was the third-strongest storm ever to hit the continental U.S.
For chronic pain sufferers, it may be smart to let sleeping dogs lie, a new University of Alberta study suggests. Contrary to blanket medical advice, shooing Fido out of the bedroom may not help people with long-term pain get a better night’s sleep, said researcher Cary Brown of the Faculty of Rehabilitation Medicine. “Typically, people who have pain also have a lot of sleep problems, so usually if they ask their health-care provider about a pet, they’re told to get the pet out of the bedroom. But that standard advice can actually be damaging.”
