And why it matters that millions got to see US presidential candidates defend their competing plans for the single biggest issue of our age.
By the time an international group of scientists stunned the world with the first ever image of a black hole, they were already planning a sequel: a movie showing how massive clouds of gas are forever sucked into the void. The Event Horizon Telescope Collaboration has already recorded the necessary observations and is processing the mountains of data to produce the first video, which will likely...
After spending five years in semi-stealth mode, a San Francisco venture called the Open Lunar Foundation is talking about its plan to create a settlement on the moon at a cost in the range of $5 billion. "At $5B, it's not only achievable within current NASA budgets, it offers the tantalizing possibility that a single passionate individual could fund the entire program as their...
A new study shows that, though students felt like they learned more from traditional lectures, they actually learned more when taking part in active learning classrooms.
In two different studies, researchers used machine learning algorithms to classify kidney biopsy samples and found substantial agreement with standard classification by pathologists. The methods may augment traditional diagnostics of kidney disease.
(SEATTLE) — 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. The expanse of unusually warm water stretches from Alaska to California, researchers with the National Oceanic and Atmospheric Administration said Thursday. It resembles a similar heat wave...

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.
A new marine heat wave spreading across a portion of the Pacific Ocean off the coast of British Columbia resembles the infamous "blob" that disrupted marine life five years...
In the quest to prove that matter can be produced without antimatter, the GERDA experiment is looking for signs of neutrinoless double beta decay. The experiment has the greatest sensitivity worldwide for detecting the decay in question. To further improve the chances of success, a follow-up project, LEGEND, uses an even more refined decay experiment.
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. The smoke from BB events produces large amounts of aerosol particles and gases. These emissions can cause major problems for visibility and health, as well as for local and...
A phalangeal fragment from Denisova Cave revealed it belonged to the member of a previously unknown human population, the Denisovans. Scientists have now measured and photographed another fragment found in Denisova Cave. Genomic analysis reveals it is the missing piece of the same phalanx whose proximal fragment enabled initial sequencing of the Denisovan genome. The scientists compared the new...
Scientists have studied the nematode worm Caenorhabditis elegans for decades, making essential contributions to basic science. In the latest milestone, scientists used cutting-edge technology to individually profile the genes expressed in more than 80,000 cells in a developing C. elegans embryo.
Among middle-aged and older adults, high blood pressure accelerated cognitive decline and treatment slowed the regression. The rate of cognitive decline was similar between adults receiving high blood pressure treatment and those who did not have high blood pressure at all.
A new study shows many OB-GYNs are uncomfortable counseling their patients on fertility at a time when more women are delaying pregnancy and needing their doctors to be more vigilant about this education.
Adults taking hot yoga had lower blood pressure measurements after three months of classes, in a small study examining hot yoga's impact on blood pressure. Hot yoga is typically a vigorous workout practiced under hot and humid conditions. Study researchers say this is one of the first studies of hot yoga's benefits in lowering blood pressure and more research is needed to determine if the practice...
A study of human gut bacteria -- known as the gut microbiome -- suggests that high blood pressure with depression may be a completely different disease than high blood pressure without depression. The gut may be targeted someday to prevent, diagnose and selectively treat different forms of high blood pressure with or without depression.
When physicians integrate with hospitals, the cost of health care rises even though there's no evidence patients get better treatment, according to a new article.
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.

Before embarking on a new research project, a thorough and exhaustive review of existing literature must be done to make sure the new project is novel. Researchers can also explore the entire body of previously published data on a subject to answer a new question using that same data. This is a daunting task, especially considering that millions of new research articles are published each year....
A recent human study has discovered the presence of fungal communities in the fetal gut. The study marks the first of its kind to observe fungal DNA in this developmental setting.
Taxing sugar-sweetened beverages by the amount of sugar they contain, rather than by the liquid volume of these drinks, as several US cities currently do, could produce even greater health benefits and economic gains, a team of researchers has concluded.
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 world's physicists have been scrambling to resolve the proton-radius puzzle. Now, a study finds a new measurement for the size of the proton at 0.833 femtometers, which is just under one trillionth of a...
When Kilauea 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.
Scientists have identified the regional character to Plasmodium falciparum across Africa. Malaria, infecting 219 million individuals in 2017, remains a threat to public health and regional stability. Human movement and the introduction of antimalarial drugs were drivers of this genetic diversity. Gene flow between sub-populations could spread resistance from one sub-population to the rest of the...
Evolutionary biologists have published findings on sex determinates of house flies. The work examines the slight difference in genetic makeup of male flies who hail from the north and those from the south. Though minute, the difference between the two types of flies is the position of the Y chromosome in the sequence of the genes.
In the wet-dry topics of Australia, drinking water in remote communities is often sourced from groundwater bores. The geochemistry of that groundwater impacts the occurrence of opportunistic pathogens in the drinking water supply, researchers now report.
Feeding the world's growing population is one of the great challenges of the 21st century, particularly in China, which has nearly a quarter of the world's population but a fraction of the cropland. A recent study looks at both the socioeconomic and environmental impacts of crop trading in China for the first time.
Researchers analyzed the genomes of 524 never before-studied ancient people, including the first genome of an individual from the ancient Indus Valley Civilization.
