U.S. wildlife officials rejected petitions Thursday to protect Yellowstone National Park's storied bison herds but pledged to consider protections for two other species—a tiny, endangered squirrel in Arizona and bees that pollinate rare desert flowers in Nevada.

A study by an assistant professor at The University of Texas at Arlington published in the Journal of Marketing shows that marketers of relatively high-priced products should consider keeping prices high, as many consumers associate high price with high quality.

In a paper in Science this week, Penn researchers report the first detailed molecular characterization of how every cell changes during animal embryonic development. The work, led by the laboratories of Perelman School of Medicine's John I. Murray, the School of Arts and Sciences' Junhyong Kim, and Robert Waterston of the University of Washington (UW), used the latest technology in the emergent...

Tropical Storm 14W has been moving through the Northwestern Pacific Ocean for several days and has now been renamed Faxai. NASA's Aqua satellite passed over the newly renamed storm and took the temperature of Faxai's clouds and storms.

Wildfires are widespread across the globe. They occur in places wherever plants are abundant—such as the raging fires currently burning in the Brazilian Amazon. Such biomass burning (BB) can be an environmental calamity.

Nearly three-quarters of Americans see weather disasters, like Hurricane Dorian, worsening and most of them blame global warming to some extent, a new poll finds.

Federal scientists said Thursday they are monitoring a new ocean heat wave off the U.S. West Coast, a development that could badly disrupt marine life including salmon, whales and sea lions.

New York unveiled its latest weapon Thursday in the city's long-running war against rats—alcohol.

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a new type of sensor that uses atoms to receive commonly used communications signals. This atom-based receiver has the potential to be smaller and work better in noisy environments than conventional radio receivers, among other possible advantages.

Young adults with student loans who participate in financial education programs become better financial managers who are able to build their personal wealth after college, researchers at the University of Illinois found in a recent study.

In the steamy, often filthy world of the humble house fly, (the Musca domestica) clear division exists among the males of the species. Though not a civil war, there are differences, to be sure, between males in the north and those that hail from the south. Finding out why those differences appear in the genetic sequences of the northerners and southerners is key to understanding nothing less than...

How much water single-family residences use is closely related to a community's built environment, according to a University of Arizona-led study. In particular, design factors such as vegetated land cover, housing density and lot size appear to have a strong impact on water use.

Scientists have designed an ultra-miniaturised device that could directly image single cells without the need for a microscope or make chemical fingerprint analysis possible from a smartphone.

Bioengineers at the University of California San Diego have developed a method to significantly extend the life of gene circuits used to instruct microbes to do things such as produce and deliver drugs, break down chemicals and serve as environmental sensors.

Coral reefs are among the most diverse and productive ecosystems on our planet. But due to climate change and other human stressors, reef-building corals that reproduce by means of broadcast-spawning—the simultaneous release of eggs and sperm into open water—may now be under threat of extinction.

York University researchers have made a precise measurement of the size of the proton—a crucial step towards solving a mystery that has preoccupied scientists around the world for the past decade.

The largest-ever study of ancient human DNA, along with the first genome of an individual from the ancient Indus Valley Civilization, reveal in unprecedented detail the shifting ancestry of Central and South Asian populations over time.

An exotic physical phenomenon, involving optical waves, synthetic magnetic fields, and time reversal, has been directly observed for the first time, following decades of attempts. The new finding could lead to realizations of what are known as topological phases, and eventually to advances toward fault-tolerant quantum computers, the researchers say.

When Kīlauea Volcano erupted in 2018, it injected millions of cubic feet of molten lava into the nutrient-poor waters off the Big Island of Hawai'i. The lava-impacted seawater contained high concentrations of nutrients that stimulated phytoplankton growth, resulting in an extensive plume of microbes that was detectable by satellite.

Hurricane Dorian, which reduced much of the northern Bahamas to rubble and left at least 20 people dead, whipped the Carolinas Thursday, bringing lashing winds, heavy rainfall and the threat of dangerous storm surge to the US east coast.

From its vantage point in orbit around the Earth, when the Global Precipitation Measurement mission or GPM core satellite passed over the Eastern Pacific Ocean, it gathered data on rainfall rates occurring in Hurricane Juliette. The areas of strongest rainfall resembled a hook.

NASA-NOAA's Suomi NPP satellite passed over the eastern Atlantic Ocean and infrared data revealed that the storm was being adversely affected by wind shear, pushing its strongest storms northeast of its center.

Tropical Storm Fernand made landfall in northeastern Mexico and began dissipating. However, infrared imagery from NASA's Aqua satellite shows that there are still fragmented strong storms left in the tropical cyclone's remnants. Those storms have the potential to generate heavy rainfall and there were warnings posted on Sept. 5.

Hurricane Dorian continues to generate tremendous amounts of rainfall, and has left over three feet of rain in some areas of the Bahamas and is now lashing the Carolinas. NASA's IMERG product provided a look at those rainfall totals.
