Killer whale DNA reveals distinct ties
The ability to transmit and receive data is crucial in space exploration. Spacecraft need robust networking capabilities to send data—including large files like photos and videos—captured by onboard instruments to Earth as well as simultaneously receiving commands from control centers. NASA has made significant strides to improve the agency's space communications capabilities while...
Kids' love for video games can improve classroom learning, study finds
Scientists have discovered that populations of Australasian killer whales revolve around matrilineal ties after using DNA to determine their populations across the region.
Magnetic 'balding' of black holes saves general relativity prediction
Kids' love for video games should be harnessed by teachers to improve classroom learning, new Australian research has found.
Why big fish thrive in protected oceans
Black holes aren't what they eat. Einstein's general relativity predicts that no matter what a black hole consumes, its external properties depend only on its mass, rotation and electric charge. All other details about its diet disappear. Astrophysicists whimsically call this the no-hair conjecture. (Black holes, they say, "have no hair.")
The pulse of the Dead Sea
Big fish are harder to find in areas sprawling with human activity, unless you're looking in no-take marine reserves, according to a new study led by marine scientists at The University of Western Australia.
Oxygen-vacancy-mediated catalysis boosts direct methanation of biomass
The Dead Sea is shrinking. There are many reasons for this: climate change is a contributing factor, as is human overuse of water as a resource. The sinking water level has a number of dangerous consequences. For example, fresh groundwater flowing downstream causes salts to dissolve in the soil, resulting in sinkholes. But it also leads to large-scale subsidence of the surrounding land surface....
Couples who disagree on savings and investment decisions are twice as likely to divorce
Biomethane (CH4) can be used as feedstock for modern chemical industry or burned directly as a fuel.
Tags to track and preserve Mary River turtles
While it is well known that fighting over money can lead couples to divorce court, new research from the University of California San Diego's Rady School of Management finds that differences in risk preferences, especially when it comes to financial matters, are likely a root cause of marital separation.
For animal societies, cohesion comes at a cost
Researchers from Charles Darwin University (CDU) are trying to find a solution to help recover the Mary River turtle population by tracking their movements with an acoustic device.
Laws of friction tested in the collapsing crater of an erupting volcano
From gaining valuable information to staying safe from predators, moving in a group can benefit animals—but at what cost? Researchers from the Max Planck Institute of Animal Behavior have provided rare insight into the physical price that animals pay for moving collectively. Using accelerometers—the equivalent of pedometers, or Fitbits—the team of scientists studied the detailed movement...
Rocket tanks of carbon-fiber–reinforced plastic are proven possible
On April 30, 2018, on the eastern flank of Hawaii's Kīlauea volcano, lava suddenly drained from a crater that had been spewing lava for more than three decades. Then the floor of the crater, named Pu'u'ō'ō, dropped out.
First test of Europe's new space brain
Future rockets could fly with tanks made of lightweight carbon fiber reinforced plastic thanks to ground-breaking research carried out within ESA's Future Launchers Preparatory Program.
What you need to know about the invasive spotted lanternfly spreading across the eastern U.S.
ESA has successfully operated a spacecraft with Europe's next-generation mission control system for the first time. The powerful software, named the "European Ground System—Common Core' (EGS-CC), will be the 'brain' of all European spaceflight operations in the years to come, and promises new possibilities for how future missions will fly.
Dams fuel malaria cases in Africa
The spotted lanternfly was first detected in Pennsylvania in 2014 and has since spread to 26 counties in that state and at least six other eastern states. It's moving into southern New England, Ohio and Indiana. This approximately 1-inch-long species from Asia has attractive polka-dotted front wings but can infest and kill trees and plants. We recently caught up with Professor Frank Hale, an...
A 20-foot sea wall won't save Miami: How living structures can help protect the coast
While dams are critical to ensuring water and food security throughout Sub-Saharan Africa, small dams in particular pose a greater risk of malaria transmission, a study says.
Malarial mosquitoes suppressed in experiments that mimic natural environments
Miami is all about the water and living life outdoors. Walking paths and parks line large stretches of downtown waterfront with a stunning bay view.
Scientists ensure high resolution measurements for carbon diplomacy
Researchers have shown "gene drive" technology, which spreads a genetic modification blocking female reproduction, works in natural-like settings.
Low upward mobility linked to early mortality
MIPT researchers have developed a multichannel laser heterodyne spectroradiometer for greenhouse gases remote sensing. Recently, the role of anthropological factors in climate change has transferred from science to economy and foreign affairs.
Monitoring the evolution of crystal dislocations in a silicene sheet
Upward mobility—the capacity to improve one's socioeconomic status—is key to realizing the American dream of a long, prosperous, and happy life, Yale researchers say. In a new study, they found a strong relationship between the lack of upward mobility early in life and increased mortality rates in young adults, particularly among Black males.
Violence against children carries a huge cost for Africa: Governments must act urgently
We might imagine crystals to be perfect structures, but they are, in fact, often plagued with "defects." Curiously enough, such defects often appear due to atoms undergoing reorganization to lower the energy of the system and attain stability.
Artificial refuges for wildlife are a popular stopgap for habitat destruction, but more research is needed
Every day, millions of children experience violence in one form or another. It is a global problem that cuts across color, class, educational status, income, ethnicity and origin.
Pine sap–based plastic: A potential gamechanger for future of sustainable materials
Wildlife worldwide is facing a housing crisis. When land is cleared for agriculture, mining, and urbanization, habitats and natural refuges go with it, such as tree hollows, rock piles and large logs.
Bushfires, not pandemic lockdowns, had biggest impact on global climate in 2020
Over the past 100 years, plastics and polymers have changed the way the world operates, from airplanes and automobiles to computers and cell phones—nearly all of which are composed of fossil fuel-based compounds. A Florida State University research team's discovery of a new plastic derived from pine sap has the potential to be a gamechanger for new sustainable materials.
Indonesia's Sinabung volcano erupts
When a team of scientists began analyzing events that influenced the world's climate in 2020, they made sure to consider the pandemic-related lockdowns that reduced emissions and led to clearer skies over many cities.
Indonesia's Mount Sinabung erupted on Wednesday, spewing a massive column of smoke and ash into the sky.
