Research finds using a large collection of simple, un-curated synthetic image generation programs to pretrain a computer vision model for image classification yields greater accuracy than employing other pretraining methods that are more costly and time consuming, and less scalable.

In a breakthrough to understand more about the mammalian brain, researchers have discovered that a vital enzyme that enables brain signals is switching on/off at random, even taking hours-long 'breaks from work'. These findings may have a major impact on our understanding of the brain and the development of pharmaceuticals.

A 'simple' tweak to perovskite solar cells during the fabrication stage could help to unlock the untold potential of the renewable energy source, according to new research.

Investigators have reported highly promising early results for CAR T therapy in a small set of patients with the autoimmune disease lupus.

A team of researchers has identified a group of human DNA sequences driving changes in brain development, digestion and immunity that seem to have evolved rapidly after our family line split from that of the chimpanzees, but before we split with the Neanderthals.

New research suggests spinal cord and brainstem are essential for processing touch signals as they travel to the brain

Hollow spheres made of MYC proteins open new doors in cancer research, scientists report.

Some clinicians have recommended vitamin D supplements to ease the muscle aches of patients taking a statin, but a new study shows the vitamin appears to have no substantial impact.

Scientists have revealed the inner workings of a key protein involved in a wide range of cellular processes -- potentially paving the way for better and less toxic cancer drugs. Using Nobel Prize-winning microscopy techniques, the researchers revealed how the tankyrase protein switches itself on and off by self-assembling into 3D chain-like structures.

Research based on data from 11,000 students in the UK charted an across-the-board fall in well-being, regardless of circumstances, between ages 11 and 14. This decline is probably linked to the transition to secondary school.

In a new study, researchers find a significant societal impact of the pandemic beyond the domain of health and raise concerns about the ability of democratic societies to cope with future crises such as the climate crisis.

By measuring immune cells in the cerebrospinal fluid when diagnosing ALS, it is possible to predict how fast the disease may progress, according to a new study.

Researchers have successfully demonstrated the transport of two-photon quantum states of light through a phase-separated Anderson localization optical fiber.

A new study suggests individuals with persistent asthma have higher levels of inflammation and artery plaque, which may increase heart attack or stroke risk. An analysis of data for more than 5,000 adults has found that those with persistent asthma appeared to be at increased risk of heart attack or stroke. Individuals with persistent asthma had nearly twice the odds of having plaque in their carotid arteries as those without asthma, after adjusting for age, sex, race/ethnicity, weight, other health conditions...

The number of green turtles breeding in Cyprus has risen in recent years -- but this bounce-back depends heavily on an Egyptian lagoon where many turtles feed, new research shows.

Sometimes healthcare professionals treat patients with opioids such as morphine to relieve symptoms, but there has been a lack of evidence as to whether this helps with severe chronic breathlessness. A randomized Phase 3 study now finds that morphine does not reduce worst breathlessness.

Are the currently approved antibody therapies used to treat individuals at increased risk for severe COVID-19 disease also effective against currently circulating viral variants? A recent study shows that the Omicron sub-lineage BQ.1.1, currently on the rise worldwide, is resistant to all approved antibody therapies.

Microplastic fibers discovered in samples (air, seawater, sediment and sea-ice) from the last remaining pristine environment on Earth.

Competing at elite level in sport is linked with an increased risk of developing osteoarthritis and joint pain in later life, a study suggests. One in four retired Olympians reported a diagnosis of osteoarthritis, the form of arthritis that causes changes in the joint and can lead to discomfort, pain and disability, the research found.

A new study assesses the number of lives lost to the COVID-19 pandemic in Russia and introduces a novel methodology that will help to get a clearer view of pandemics in the future.

A multi-institution research team has developed an optical chip that can train machine learning hardware.

A decline in the element molybdenum across the planet's oceans preceded a significant extinction event approximately 183 million years ago, new research shows.

Scientists have developed a technique to convert waste paper, from single-use packaging and bags, and cardboard boxes, into a crucial component of lithium-ion batteries. Through a process called carbonisation which converts paper into pure carbon, the researchers turned the paper's fibers into electrodes, which can be made into rechargeable batteries that power mobile phones, medical equipment, and electric vehicles.
