The Global Precipitation Measurement mission or GPM core satellite provided information about the rate in which rain was falling within the Eastern Atlantic Ocean's latest tropical storm, Gabrielle.
Intrepid Brazilian and British scientists say they have located the Amazon's tallest tree in northern Brazil, untouched by a spate of wildfires that have raged in the rainforest for weeks. The scientists say they located an unusually large specimen of the giant Dinizia Excelsa species -- measuring 88 meters (288-feet) with a circumference of 5.50 meters -- in a sanctuary of other Dinizia trees....
A Himalayan lake was the final resting place of an estimated 800 skeletons. Researchers still don't know what killed...
A new vaccine has the potential to treat and prevent toxic shock caused by invasive streptococcal disease, which kills more than 160,000 people every year. When ISD occurs, some strains can make more toxins than others and cause streptococcal toxic shock syndrome (STSS). Now that antibodies have been generated, the next step would be to make monoclonal antibodies that could be suitable for a human...
Grey squirrels eavesdrop on the chatter between nearby songbirds as a sign of safety.
A new mathematical model provides support for environmental taxation, such as carbon taxes, as an effective strategy to promote environmentally friendly practices without slowing economic growth.
Animals not only tune in to alarm cries or ‘all-clear’ signals from other speciesSquirrels eavesdrop on the chatter of songbirds to work out whether the appearance of a predator is cause for alarm, researchers have found.Animals including squirrels have previously been found to tune in to cries of alarm from other creatures, while some take note of “all-clear” signals from another species...
Plastic pollution has entered the fossil record, research showsPlastic pollution is being deposited into the fossil record, research has found, with contamination increasing exponentially since 1945.Scientists suggest the plastic layers could be used to mark the start of the Anthropocene, the proposed geological epoch in which human activities have come to dominate the planet. They say after the...
when they feel safe to communicate the absence of danger or share their location. This "chatter" from multiple bird species could therefore be a useful cue to other creatures that there is no imminent threat.
A new mathematical model provides support for environmental taxation, such as carbon taxes, as an effective strategy to promote environmentally friendly practices without slowing economic growth. Xinghua Fan and colleagues at Jiangsu University, China, publish their model and findings in the open-access journal PLOS ONE on September 4, 2019.
Planned Parenthood is seeking a new approach to expand health services after the recent $60 million in funding cuts from Trump's "gag...
In summer heat, cities may swelter more than nearby suburbs and rural areas. And while the size of this urban heat island effect varies widely among the world's cities, heat island intensity can largely be explained by a city's population and precipitation level, researchers have reported. The analysis suggests that cooling cities by planting more vegetation may be more effective in drier regions...
Researchers have developed a new model to optimize radiation therapy and significantly increase the number of tumor cells killed during treatment. The new mathematical model can use information about where the majority of the cells in a tumor are located allowing for radiation treatment to be administered to the densest area.
LEDs made of indium gallium nitride provide better luminescence efficiency than many of the other materials used to create blue and green LEDs, but a big challenge of working with InGaN is its known dislocation density defects that make it difficult to understand its emission properties. Researchers report an InGaN LED structure with high luminescence efficiency and what is believed to be the...
A new clinical guideline provides recommendations on the use of radiation therapy to treat patients diagnosed with pancreatic cancer, including when radiation treatments are appropriate; optimal dosing, timing and fractionation; and strategies to prevent and mitigate common side effects of treatment.
Single-sex prawns could help alleviate poverty, reduce disease and protect the environment, according to researchers v who have developed a monosex prawn that may make this winning trifecta possible.
Scientists discover the secret behind some protein transporters' superiority. One transporter, MAE1, can export organic acids out of yeast spending close-to-zero energy. Organic acids are utilized as building blocks for plastic and rubber, and the finding could become important in industrial biotech.
A geoscientist calls the unearthed fossils, including the bodies and trails left by an ancient animal species, the most convincing sign of ancient animal mobility, dating back about 550 million years.
A recent study investigated around 100,000 localized seismic events to search for patterns in the data. Scientists discovered that earthquakes of differing magnitudes have more in common than was previously thought. This suggests development of early warning systems may be more difficult than hoped. But conversely, similarities between some events indicate that predictable characteristics may aid...
A recent study has investigated around 100,000 localized seismic events to search for patterns in the data. University of Tokyo Professor Satoshi Ide discovered that earthquakes of differing magnitudes have more in common than was previously thought. This suggests development of early warning systems may be more difficult than hoped. But conversely, similarities between some events indicate that...
In a remarkable evolutionary discovery, a team of scientists co-led by a Virginia Tech geoscientist has discovered what could be among the first trails made by animals on the surface of the Earth roughly a half-billion years ago.
Many voters today seem to live in partisan bubbles, where they receive only partial information about how others feel regarding political issues. Now, an experiment developed in part by MIT researchers sheds light on how this phenomenon influences people when they vote.
In summer heat, cities may swelter more than nearby suburbs and rural areas. And while the size of this urban heat island effect varies widely among the world's cities, heat island intensity can largely be explained by a city's population and precipitation level, researchers reported in a paper published Sept. 4 in the journal Nature.
Quasars are the universe's brightest beacons; shining with magnitudes more luminosity than entire galaxies and the stars they contain. In the center of this light, at the heart of a quasar, researchers think, is an all-consuming black hole.
Tyrannosaurus rex, one of the largest meat-eating dinosaurs on the planet, had an air conditioner in its head, suggest scientists who are challenging over a century of previous beliefs.
