Across all England's regions, a study appearing in the journal Policing & Society spotlights London's Metropolitan Police as the area where women trust the least.
Soil bacteria help regulate the cycling of carbon and nutrients on Earth. Over time, these bacteria have evolved strategies that determine where they live, what they do, and how they deal with a changing environment. However, microbiologists do not fully understand how bacteria's genes relate to their life strategies.
Silicon-based electronics are approaching their physical limitations and new materials are needed to keep up with current technological demands. Two-dimensional (2D) materials have a rich array of properties, including superconductivity and magnetism, and are promising candidates for use in electronic systems, such as transistors. However, precisely controlling the properties of these materials is extraordinarily difficult.
Humans, Homo sapiens, have unique features compared with other closely related hominin species and primates, including the shape of the base of the skull. The evolutionary changes underlying these features were significant in allowing the evolution of our increased brain size.
Policing of intimate partner violence (IPV) may result in adverse consequences for survivors, according to a new study at Columbia University Mailman School of Public Health. However, the evidence concerning the generalized consequences of IPV policing has not been comprehensively evaluated until now and the results call into question whether IPV policing benefits survivors.
NASA is planning to repair NICER (Neutron star Interior Composition Explorer), an X-ray telescope on the International Space Station, during a spacewalk later this year. It will be the fourth science observatory in orbit serviced by astronauts.
A consortium made up of researchers from more than ten countries, including Brazil, the United States and some European nations, is running simulations of the past and future climate in South America with unprecedented resolution. The aim is to create a computer visualization model that more accurately represents the hydroclimatic processes that occur in the region to help decision makers implement more effective measures to adapt to the impacts of climate change.
Globally, last year was the warmest for thousands of years, with a globally averaged temperature of at least 1.45°C greater than pre-industrial times. The year also saw an unprecedented string of extreme weather and climate events in many parts of the world, including heat waves, torrential rainfall, transitions from drought to floods, wildfires, and sandstorms.
It is a common hack to stretch a balloon out to make it easier to inflate. When the balloon stretches, the width crosswise shrinks to the size of a string. Noah Stocek, a Ph.D. student collaborating with Western physicist Giovanni Fanchini, has developed a new nanomaterial that demonstrates the opposite of this phenomenon.
A NASA mission testing a new way of navigating our solar system is ready to hoist its sail into space—not to catch the wind, but the propulsive power of sunlight. The Advanced Composite Solar Sail System is targeting launch on Tuesday, April 23 (Wednesday, April 24 in New Zealand) aboard a Rocket Lab Electron rocket from the company's Launch Complex 1 on the Mahia Peninsula of New Zealand.
In 1969, the recently independent Republic of Congo discovered an enormous oil field off its coast. The find represented both a rare opportunity for the burgeoning nation, and a potential threat—the revenue generated by oil extraction could either pave the way for a stable socialist society, or doom the country to exploitation much like that it had endured under French colonialism.
Engineers at L3Harris Technologies in Rochester, New York, have combined all 10 mirrors for NASA's Nancy Grace Roman Space Telescope. Preliminary tests show the newly aligned optics, collectively called the IOA (Imaging Optics Assembly), will direct light into Roman's science instruments extremely precisely. This will yield crisp images of space once the observatory launches.
