From dry to deluge, how heavy snow, rain flooded Yellowstone
Just three months ago, the Yellowstone region like most of the West was dragging through an extended drought with little snow in the mountains and wildfire scars in Red Lodge from a year ago when the area was hit by 105-degree Fahrenheit (40.5 Celsius) heat and fire.
Electrons take the fast and slow lanes at the same time
Imagine a road with two lanes in each direction. One lane is for slow cars, and the other is for fast ones. For electrons moving along a quantum wire, researchers in Cambridge and Frankfurt have discovered that there are also two "lanes," but electrons can take both at the same time!
Electrocuted birds are sparking wildfires
In 2014, a wildfire ripped through central Chile, destroying 2500 homes and
killing at least 13 people
. A year later, a blaze in Idaho burned more than 4000 hectares, an area nearly 12 times the size of New York City’s Central Park. Both conflagrations had one thing in common: Experts believe they were started by birds.

The European Gaia space mission has produced an unprecedented amount of new, improved, and detailed data for almost two billion objects in the Milky Way galaxy and the surrounding cosmos. The Gaia Data Release 3 on Monday revolutionizes our knowledge of the Solar System and the Milky Way and its satellite galaxies.
Invasive species are taking over some American forests

A new botanical survey of southwest Ohio found that invasive species introduced to the United States over the past century are crowding out many native plants.
NASA Insists All Is Well as the Webb Telescope’s Mirror Gets Dinged
In some ways, the last place you’d want to put the James Webb Space Telescope is, well, in space. If you owned a $10 billion car, you wouldn’t leave it out in a hail storm, and while there’s no hail in space, there are plenty of micrometeoroids—high speed debris no bigger than a dust grain but moving so fast they can pack a true destructive wallop. Every day, millions of...
Moth wings could inspire a new generation of soundproofing material
Bob McDonald's blog: The moth's wings can absorb up to 87% of incoming sound, a handy trait when being hunted by a...
Neuroscientists create maps of the brain after traumatic brain injury

Scientists have discovered that an injury to one part of the brain changes the connections between nerve cells across the entire brain.
Scientists serendipitously discover rare cluster compound
- ScienceDaily
- 22/6/17 20:34
Scientists at Kyoto University's Institute for Cell-Material Sciences have discovered a novel cluster compound that could prove useful as a catalyst. Compounds, called polyoxometalates, contain a large metal-oxide cluster carry a negative charge. They are found everywhere, from anti-viral medicines to rechargeable batteries and flash memory devices.
Rethinking the rabies vaccine

Researchers may have discovered the path to better rabies vaccine design. Researchers share one of the first high-resolution looks at the rabies virus glycoprotein in its vulnerable 'trimeric' form.

Softening tough tissue in aging ovaries may help fight infertility
Would-be parents hoping to get pregnant face a ticking clock: The older potential mothers get, the more their fertility drops. A new study in mice may help explain why. Ovaries accumulate “stiff” tissue as they age, and researchers have found that reducing the amount of this tissue—“softening” the ovaries, as it were—restored fertility in the animals, raising the possibility...
Researchers explore new method for glacial melt reduction
Glaciers are experiencing fast and significant changes under global warming. Glacier shrinkage significantly impacts global sea level, regional water cycles, ecosystems, and natural hazards.
As staghorn coral declines along Florida coast, planting project tests restoration plan
Just 150 fragments of staghorn coral planted off Florida's shore might give new hope to the state's endangered reefs.
Calling all snake hunters—Florida opens registration for this year's Python Challenge
Have you ever wanted to become a snake hunter in the Florida Everglades? Now's your chance.
Gun violence policy is focusing on mental health but Federal records still lack some states
Federal officials say the FBI's database of people prohibited from purchasing firearms only works if it has "complete, accurate and timely information."
Low-income renters can't afford rent in nearly 45% of America's largest metro areas
Metro areas in the United States have become increasingly unaffordable to residents, especially Black and Latino Americans, finds a new report from the USC Dornsife Equity Research Institute (ERI), published by the National Equity Atlas.
New proton capture reaction rate of copper-57 changes nucleosynthesis paths in Type-I X-ray burst
An international research team has recently developed a new proton capture reaction rate of copper-57 for the extreme astrophysical environment at the surface of neutron stars. The researchers found that the new reaction rate changes some of the most critical nucleosynthesis paths in Type-I X-ray bursts.
Examining the impact of herbicide-resistant crops on weed management
Herbicide-resistant crops are now commonplace in the U.S. and Canada. With proper stewardship, these same crop-trait technologies can also play a key role in integrated weed management—reducing the intensity of herbicide use and the selection pressure on weed populations. But does this weed management potential match the reality in the field?
How Climate Change and Air Pollution Affect Kids’ Health
Climate change affects everyone, but especially children. Their small bodies—and the fact that they grow so rapidly, starting from the time they’re in utero—make them more vulnerable to toxins, pollution, and other climate-change fallout. Over their lifetimes, kids also face greater exposure to the damage of climate change than adults.

How keeping trees when clearing pastures could reduce climate consequences
Land use change, like cutting down a forest to make way for agriculture, can be a major contributor to climate change by releasing greenhouse gases into the atmosphere. Researchers at the University of New Hampshire studied a practice known as silvopasture which intentionally preserves trees in pastures where livestock graze. They found that compared to a completely cleared, tree-less, open...
