New plan targets salmon-eating sea lions in Columbia River
More than 1,100 sea lions could be killed annually along a stretch of the Columbia River on the Oregon-Washington border to boost faltering populations of salmon and steelhead, federal officials said Friday. The National Marine Fisheries Service said it's taking public comments through Oct. 29 on the plan requested by Idaho, Oregon, Washington, and Native American tribes. "The changes in the...

Hurricane puts 10 million in the crosshairs in Florida
An increasingly alarming Hurricane Dorian menaced a corridor of some 10 million people—and put Walt Disney World and President Donald Trump's Mar-a-Lago resort in the crosshairs—as it steamed toward Florida on Friday with the potential to become the most powerful storm to hit the state's east coast in nearly 30 years.
NASA satellites on-hand as Dorian becomes a category 3 hurricane
As Hurricane Dorian was upgraded to a Category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale, NASA's fleet of satellites were gathering data during the day to assist weather forecasters and scientists. At 2:00 pm EDT the National Hurricane Center (NHC) posted a supplemental advisory. NHC reports that "extremely dangerous Hurricane Dorian poses a significant threat to Florida and the...

Early start of 20th century arctic sea ice decline
Boulder, Colo., USA: Arctic sea-ice has decreased rapidly during the last decades in concert with substantial global surface warming. Both have happened much faster than predicted by climate models, and observed Arctic warming is much stronger than the global average. Projections suggest that Arctic summer sea-ice may virtually disappear within the course of the next fifty or even thirty years.
Moving faster in a crowd
Cell particles move more quickly through a crowded cellular environment when the crowding molecules are non-uniformly distributed. New research also shows that particle transport in crowded cells can actually be faster than movement in a non-crowded environment as long as the particles are moving from densely crowded areas to less crowded areas. Understanding the rate at which particles move in...
Oxygen depletion in ancient oceans caused major mass extinction
Late in the prehistoric Silurian Period, around 420 million years ago, a devastating mass extinction event wiped 23 percent of all marine animals from the face of the planet.
The 'universal break-up criterion' of hot, flowing lava?
Thomas Jones' "universal break-up criterion" won't help with meltdowns of the heart, but it will help volcanologists study changing lava conditions in common volcanic eruptions.
Climate activist Thunberg joins hundreds of teens at UN protest
Swedish climate change campaigner Greta Thunberg joined hundreds of other teenagers protesting outside the United Nations Friday in her first demonstration on US soil since arriving by zero-carbon yacht. Thunberg, 16, has spurred teenagers and students around the world to gather every Friday under the rallying cry "Fridays for future" to call on adults to act now to save the planet. "Stop...

How to simulate softness
- ScienceDaily
- 19/8/30 21:08
What factors affect how human touch perceives softness, like the feel of pressing your fingertip against a marshmallow, a piece of clay or a rubber ball? By exploring this question in detail, researchers discovered clever tricks to design materials that replicate different levels of perceived softness. The findings provide fundamental insights into designing tactile materials and haptic interfaces...
Discovery paves the way for earlier detection of type 1 disease
- ScienceDaily
- 19/8/30 21:08
Scientists have discovered what may be the earliest possible biological marker of type 1 diabetes, formerly known as juvenile type 1 diabetes. If their mouse study can be replicated in humans, which they are now attempting to do, the timing of therapeutic intervention may be drastically improved for patients who are on course to develop the disease.
Oxygen depletion in ancient oceans caused major mass extinction

- 19/8/30 21:08
For years, scientists struggled to connect a mechanism to this mass extinction, one of the 10 most dramatic ever recorded in Earth's history. Now, researchers have confirmed that this event, referred to by scientists as the Lau/Kozlowskii extinction, was triggered by an all-too-familiar culprit: rapid and widespread depletion of oxygen in the global oceans.
