Researchers have proposed a new evolutionary model for the origin of a kingdom of viruses called Bamfordvirae, suggesting a billion-years evolutionary arms race between two groups within this kingdom and their hosts.
The first building blocks of life on Earth may have formed thanks to eruptions from our Sun, a new study finds. A series of chemical experiments show how solar particles, colliding with gases in Earth's early atmosphere, can form amino acids and carboxylic acids, the basic building blocks of proteins and organic life.
According to researchers, a new analysis of an 80-million-year-old permineralized pollen cone found in the Campanian Holz Shale formation located in Silverado Canyon, California, offers a more accurate cycad natural history -- one where the plants diversified during the Cretaceous.
Like animals, many plant species are struggling to adapt to a human-dominated planet. However, plants are often overlooked in conservation efforts, even though they are cheaper and easier to protect than animals and play a pivotal role in bolstering our food, fuel, and medical systems. A plant ecologist suggests an approach for preventing all future land plant extinctions across the globe which...
A team has modeled improving photosynthesis through enzyme modification and simulated soybean growth with realistic climate conditions, determining to what extent the improvements in photosynthesis could result in increased yields.
Using a "spooky" phenomenon of quantum physics, researchers have discovered a way to double the resolution of light microscopes.
Drought is so severe in parts of Spain that thousands of people are invoking the heavens desperate for rain.
What makes a good parent? Most would say a good parent loves and nurtures their child with the ultimate aim of helping them flourish—now and into the future. A good parent will feed their child, give them space to play and time to use their imagination, make sure they get an education and medical care, listen to their troubles, and teach them to one day be autonomous adults.
A new study that analyzed 17 years of migratory bird-nesting data in Prudhoe Bay, Alaska, revealed that nest survival decreased significantly near high-use oil and gas infrastructure and its related noise, dust, traffic, air pollution, and other disturbances.
Justice reinvestment emerged in the United States more than 20 years ago as a way to reduce mass incarceration and its vast costs by addressing the social drivers of imprisonment.
Most people would expect a freezer can keep perishable food fresh and safe from spoilage for many months. Unfortunately, this is not always the case.
Skoltech researchers reported another breakthrough in their investigations of diatoms, the fascinating single-cell algae that may hold many secrets to advanced technological solutions emulating nature.
Germany called Tuesday for governments around the world to work on setting an ambitious target for renewable energy that would "ring in the end of the fossil fuel age" and help prevent dangerous global warming.
Parents share content of their children for myriad reasons, including to connect with friends and family, and to seek validation or support.
Using a "spooky" phenomenon of quantum physics, Caltech researchers have discovered a way to double the resolution of light microscopes.
Working with a great deal of dexterity and concentration, Jingo Bozzini, an electronics engineer, solders the tiny legs of a chip onto the green circuit board. "Soldering isn't my strong suit," he grins. He's much more interested in programming the circuit on the chip, which was also the focus of his final practical exam last year.
Jose Viator was hoping tourists would flock to his beachside bar on the French archipelago of Guadeloupe, but he has been forced to close because of stinky brown seaweed.
Giving new college students opportunities to reflect on the ways science, technology, engineering and math can affect their lives makes them more likely to remain in degree programs in STEM fields, according to new research from the University of Wisconsin–Madison.
Rusby Contreras-Díaz was scrolling through a biodiversity database, looking at places where people had spotted margays and jaguars, when she noticed something odd: Every location had an uncertainty of 30 kilometers. Contreras-Díaz—a mammologist at the National Autonomous University of Mexico—had hoped to use the observations to map where the two carnivores were found in Mexico....

The Super Pressure Balloon-borne Imaging Telescope (SuperBIT) launched from Wānaka, New Zealand, on April 16 and has already captured stunning images of the Tarantula Nebula, kickstarting its 100-day hunt for dark matter. The helium-filled super pressure balloon, which is about the size of a football stadium, can reach an altitude of about 110,000 feet (21Continue reading "First image from new...
Applying machine learning models, a type of artificial intelligence (AI), to data collected passively from wearable devices can identify a patient's degree of resilience and well-being, according to investigators. The findings support wearable devices as a way to monitor and assess psychological states remotely without requiring the completion of mental health questionnaires.
