A phase 3 clinical trial tested the safety and efficacy of teriflunomide, an oral immunomodulatory drug, in children with multiple sclerosis. Although the medication did not prevent disease relapses to a greater extent than placebo, the option for some patients to switch from placebo to teriflunomide before the end of the trial likely biased the results against treatment efficacy. The drug...

Current approaches to create superconducting qubits for quantum computers yield chips that are substantially larger than those found in classical computers. To shrink things down, researchers have taken advantage of atomically thin, 2D materials to construct the necessary capacitors for superconducting qubits. Their two-qubit chip is 1,000x smaller than those made with conventional fabrication...

Scientists have documented the discovery of two new species of fossilized armored worms in Australia -- Lepidocoleus caliburnus and Lepidocoleus shurikenus -- dating from about 400 million years ago. Then, using the micro-CT imaging capabilities of the MU X-ray Microanalysis Core facility, the researchers were able to develop first-of-its-kind digital 3D-models of the species' individual armor...

Researchers have confirmed a link between altered DNA repair and increased DNA damage associated with spinocerebellar ataxia type 7 (SCA7), a debilitating, sometimes deadly neurodegenerative condition causing movement disorders. Their work also revealed a potential therapeutic target for the currently incurable and difficult to treat condition.

Combining knowledge of chemistry, physics, biology, and engineering, scientists from McGill University develop a biomaterial tough enough to repair the heart, muscles, and vocal cords, representing a major advance in regenerative medicine.

Scientists recently discovered that water was once present in a region of Mars called Arabia Terra.

Biomedical engineers have engineered a holographic system capable of imaging and analyzing tens of thousands of cells per minute to both discover and recognize signs of disease.

Monsoons are continental weather events produced when intense summer sunlight heats land more than ocean. But new supercomputer simulations show that North America's only monsoon works differently. The North American monsoon, which drenches western Mexico and the American Southwest each summer, is generated when the jet stream collides with the Sierra Madre mountains, which diverts it southward...

As an autoimmune disease, Type 1 diabetes raises important questions about immune cell activity that have broad implications for immunotherapy.

A new decision-making framework designed by an international team of fisheries researchers can help fisheries bolster their ability to adapt to a warming world. The tool is meant to take a lot of the guesswork out of finding resilience in a time of climate change.

Researchers have created and observed a new phase of matter, popularly known as a time crystal.

Car tailpipes spew out molecules of ammonia, a harmful air pollutant that can lead to thousands of premature deaths every year. New research shows that vehicles may produce a lot more of these emissions than federal and state regulators have believed.

Ever since the first barcode appeared on a pack of chewing gum in 1974, the now-ubiquitous system has enabled manufacturers, retailers and consumers to quickly and effectively identify, characterize, locate and track products and materials. Scientists now demonstrate how they can do the same thing at the molecular level, studying the ways cancer cells 'talk' with one another.

New clinical research indicates that a widely used food additive, carboxymethylcellulose, alters the intestinal environment of healthy persons, perturbing levels of beneficial bacteria and nutrients. These findings demonstrate the need for further study of the long-term impacts of this food additive on health.

Botonists reveals that the unique timing of spore dispersal in the sensitive fern, known as Onoclea sensibilis, is determined by a structural mechanism of humidity-driven movement in spore bearing leaves.

Scientists describe development of a cost-effective Scotch-tape-like film that can be applied to perovskite solar cells and capture 99.9% of leaked lead in the event of solar cell damage.

Archaeologists have unearthed the first Roman mosaic of its kind in the UK.

New research suggests that effective wound healing may be aided by replicating a crucial component of our blood.

In mice with high-risk neuroblastoma, tumors disappeared in response to a new combination treatment with precision medicines, a recent study shows. This is a vital step toward a potentially curative treatment for a form of cancer affecting young children that is currently difficult to treat.

New research gives a bird's-eye view of the scale of plastic creation globally, tracing where it's produced, where it ends up, and its environmental impact.

It is widely understood that antibodies neutralize viruses by latching onto their surfaces and blocking them from infecting host cells. But new research reveals that this barrier method isn't the only way that antibodies disable viruses. An international team of researchers has discovered that antibodies also distort viruses, thereby preventing them from properly attaching to and entering cells.

Scientists can control brain circuits, behavior, and emotion using light. Researchers developed a new optogenetic tool, 'Opto-vTrap', which is expected to contribute to treatment for epilepsy, muscle spasms, and skin wrinkles.

Lasers in conventional laser printers for paper printouts are very small. 3D laser printers for 3-dimensional microstructures and nanostructures, by contrast, have required big and expensive laser systems so far. Researchers now use another process for this purpose. Two-step absorption works with inexpensive and small, blue laser diodes. As a result, much smaller printers can be used.

An analysis in the lead up to World AIDS Day reveals that HIV is 'virally suppressed' in only 59 per cent of children and adolescents on treatment.
