In a new paper, researchers report a camera that could offer a much less expensive way to achieve ultrafast imaging for a wide range of applications such as real-time monitoring of drug delivery or high-speed lidar systems for autonomous driving. Researchers show that their new diffraction-gated real-time ultrahigh-speed mapping (DRUM) camera can capture a dynamic event in a single exposure at 4.8 million frames per second. Read more ›

When people feel that their resources are scarce -- that they don't have enough money or time to meet their needs -- they often make decisions that favor short-term gains over long-term benefits. Because of that, researchers have argued that scarcity pushes people to make myopic, impulsive decisions. But a study provides support for a different, less widely held view: People experiencing scarcity make reasonable decisions based on their circumstances,... Read more ›

To obtain the biggest cherry harvest, trees should be pollinated by both honey bees and mason bees. This new study shows yet another benefit of biodiversity. Read more ›

It's a skin disorder that makes life miserable for around 800 million teenagers and adults worldwide, but cientists may have found an effective treatment for acne, delivered via tiny nanoparticles. Read more ›

Rock faces in Namibia are decorated with hundreds of stone-age images not only of animals and human footprints, but also of animal tracks. These have been largely neglected to date as researchers lacked the knowledge required to interpret them. Archaeologists have now worked together with animal tracking experts to investigate the engraved animal tracks on six rock faces in more detail, and were able to determine detailed information on the...

Prioritizing career goals over fun and freedom doesn't make your life better, researchers have found. The study across three countries discovered people who prioritized achievement over enjoyment were less happy on the next day. Read more ›

Researchers have successfully demonstrated that hagfish slime proteins can accurately replicate membranes in the human eye. Scientists were able to properly grow retinal cells on hagfish slime proteins and prove that the protein's behavior changes as the membrane mimics stages of aging and disease. Read more ›

Researchers have developed small robotic devices that can change how they move through the air by 'snapping' into a folded position during their descent. Each device has an onboard battery-free actuator, a solar power-harvesting circuit and controller to trigger these shape changes in mid-air. Read more ›

During a bout of influenza, B cells interact with other immune cells and then take different paths to defend the body. One path is the B cells that differentiate into lung-resident memory B cells, or lung-BRMs, that are critical for pulmonary immunity. These long-lived, non-circulating lung-BRMs migrate to the lungs from draining lymph nodes and reside there permanently as the first layer of defense that can quickly react to produce... Read more ›

Western University has developed a ground-breaking method for predicting which intensive care unit (ICU) patients will survive a severe brain injury by combining functional magnetic resonance imaging (fMRI) with state-of-the art machine learning techniques. Read more ›

If the Chicago region replaced 30% of all on-road combustion-engine vehicles -- including motorcycles, passenger cars and trucks, buses, refuse trucks and short- and long-haul trucks -- with electric versions, it would annually save more than 1,000 lives and over $10 billion, according to a new study.

Some crop pathogens use a clever trick to multiply and spread infection: they hijack the plant's cellular plumbing. In a new study, researchers unveil a class of bacterial proteins that fold into a straw-like shape and insert themselves into the plant cell membrane, allowing the inside of the leaf to become waterlogged. The researchers also figured out a possible way to block the water channel proteins and prevent infection. Read more ›

Researchers have developed an artificial intelligence (AI) system that has the potential to not only identify sight-threatening eye diseases but also predict general health, including heart attacks, stroke, and Parkinson's disease. Read more ›

Scientists have created a process that can upcycle most plastics into chemicals useful for energy storage, using light-emitting diodes (LEDs) and a commercially available catalyst, all at room temperature. The new process is very energy-efficient and can be easily powered by renewable energy in the future, unlike other heat-driven recycling processes like pyrolysis. Currently, only nine per cent of plastics globally are recycled and the rest are typically discarded in... Read more ›

Scientists are trying to raise as many urchins as possible because they eat algae that could otherwise smother reef ecosystems and kill corals. Researchers have identified algae on which larval sea urchins grow into juveniles in a lab setting. Read more ›

Sitting calmly in their webs, many spiders wait for prey to come to them. Arachnids along lakes and rivers eat aquatic insects, such as dragonflies. But, when these insects live in mercury-contaminated waterways, they can pass the metal along to the spiders that feed on them. Now, researchers have demonstrated how some shoreline spiders can move mercury contamination from riverbeds up the food chain to land animals. Read more ›

One of the most interesting and important questions in cosmology is, 'How much matter exists in the universe?' An international team has now succeeded in measuring the total amount of matter for the second time. The team determined that matter makes up 31% of the total amount of matter and energy in the universe, with the remainder consisting of dark energy. Read more ›

A new study finds that a natural compound found in many plants inhibits the growth of drug-resistant Candida fungi -- including its most virulent species, Candida auris, an emerging global health threat. Read more ›
