As tensions between China and the United States ratchet up, former California Gov. Jerry Brown sees a way to bring together the world's largest carbon emitter and a U.S. state that's leading the way in energy standards: climate change.
Leader after leader told the United Nations on Monday that they will do more to prevent a warming world from reaching even more dangerous levels. But as they made their pledges at the Climate Action Summit, they and others conceded it was not enough.
The extent of Arctic sea ice at the end of this summer was effectively tied with 2007 and 2016 for second lowest since modern record keeping began in the late 1970s. An analysis of satellite data by NASA and the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder shows that the 2019 minimum extent, which was likely reached on Sept. 18, measured 1.60 million square miles...
Mosasaurs were true sea monsters of late Cretaceous seas. These marine lizards—related to modern snakes and monitor lizards—grew as long as fifty feet, flashed two rows of sharp teeth, and shredded their victims with enormous, powerful jaws.
The ancient Incan sanctuary of Machu Picchu is considered one of humanity's greatest architectural achievements. Built in a remote Andean setting atop a narrow ridge high above a precipitous river canyon, the site is renowned for its perfect integration with the spectacular landscape. But the sanctuary's location has long puzzled scientists: Why did the Incas build their masterpiece in such an...
The Ecological Society of America (ESA) announces the publication of a new report, "Impacts to Wildlife of Wind Energy Siting and Operation in the United States," in ESA's Issues in Ecology publication.
With the recent celebration of the 50th anniversary of the Apollo program's first landing of humans on the moon, the eyes and hopes of the world turn skyward again.
Researchers have developed a tiny nanolaser that can function inside of living tissues without harming them.
Researchers from North Carolina State University have found that dogs can suffer from the same type of autoimmune encephalitis that people do. The finding could lead to better screening methods for diagnosis and possibly more effective treatments for canine encephalitis.
Tropical Storm Tapah had taken on an elongated shape as it moved through the Sea of Japan, between South Korea and Japan. When the Global Precipitation Measurement mission or GPM core satellite passed over Tapah, it measured rainfall as the storm was becoming extra-tropical.
As Tropical Storm Lorena was nearing landfall in northwestern Mexico, NASA-NOAA's Suomi NPP satellite provided forecasters with an image of the storm. By Monday, Sept. 23, Lorena's remnants were affecting the southern U.S. and bringing heavy rainfall to Arizona.
Satellite imagery can be used to peer inside a storm as well as assess the storm's outside shape to give forecasters understanding of what's happening to it. NASA-NOAA's Suomi NPP satellite provided forecasters with a visible image of a less-organized Karen after it moved into the Caribbean Sea and encountered wind shear.
Forecasters use a variety of satellite imagery to understand what's happening in a storm, and sometimes just a visible picture can tell a lot. NASA-NOAA's Suomi NPP satellite provided forecasters with a visible image of the storm that showed wind shear was pushing clouds away from the storm's center.
NASA-NOAA's Suomi NPP satellite imagery revealed that Tropical Storm Kiko had a tight circulation center.
NASA calculated the rainfall rates in the Atlantic Ocean's newest tropical cyclone, Lorenzo.
Cracking an egg to release its yolk requires applying external force (like being smacked against the edge of a bowl) to overcome the strength of the eggshell. Similarly, delivering microcapsule-contained therapeutic biomolecules into the human body requires that their containers be broken after they are injected, so that the cargo can be delivered in the right place at the right time. A number of...
Researchers at the University of Illinois at Urbana-Champaign have constructed a quantum-mechanical state in which the colors of three photons are entangled with each other. The state is a special combination, called a W state, that retains some entanglement even if one of the three photons is lost, which makes it useful for quantum communication. Such entangled states also enable novel quantum...
From habitat loss to climate change, amphibians around the world face immense threats to their survival. One emerging and sinister threat is the chytrid fungus, a mysterious pathogen that kills amphibians by disrupting the delicate moisture balance maintained by their skin, and that is decimating frog populations around the world.
Diving seabirds watch each other to work out when to dive, new research shows.
Fundamentalist Christians tap into their willingness to sacrifice to conserve water and energy, shop environmentally and protect the Earth, according to a Michigan State University (MSU) study.
Chatbots, which use artificial intelligence to simulate human conversation through voice commands or text chats, incur almost zero marginal costs and can outsell some human employees by four times, so why aren't they used more often? According to new research, the main contributor is customer pushback.
The Digital Life team at the University of Massachusetts Amherst led by evolutionary biologist Duncan Irschick and other colleagues released the world's first accurate, publicly available three-dimensional (3-D) model of the rare Southern white rhino in collaboration with Perth Zoo in Australia.
From soda bottles to polyester clothing, ethylene is part of many products we use every day. In part to meet demand, the Shell Oil Company is building an ethane cracker plant in Beaver County, Pa., specifically to produce ethylene molecules from the abundant ethane found in natural gas. However, the chemical reaction used to convert ethane into valuable ethylene is incomplete, so such plants...
Rice University researchers have found a way to track the formation of soluble amyloid beta peptide aggregates implicated in the onset of Alzheimer's disease.
