Researchers have developed an 'off-the-shelf' artificial cardiac patch that can deliver cardiac cell-derived healing factors directly to the site of heart attack injury.

Physicists have developed the first high-repetition-rate laser source that produces coherent soft x-rays spanning the entire 'water window'. That technological breakthrough should enable a broad range of studies in the biological, chemical and material sciences as well as in physics.

Scientists studying bacteria have identified the roots of a behavior that is regulated by the circadian clock. The research provides a striking example of the importance of keeping the internal biological clock aligned with the external environment so that key processes occur at the right time of day.

A unique butterfly breeding experiment gave researchers an opportunity to study the physical and genetic changes underlying the evolution of structural color, responsible for butterflies' iridescent purples, blues and greens. Using helium ion microscopy, the scientists discovered that a 75% increase in thickness of the chitin lamina of wing scales turned iridescent gold to shiny blue. They showed...

Personal growth and job skills have taken a backseat to an increased focus on standardized test scores in schools across the nation, according to new research.

Medical marijuana users who say they have high levels of pain are more likely than those with low pain to say they use cannabis three or more times a day, a new study finds. However, daily marijuana users with severe pain also reported their health had become worse in the past year.

Parents who are using popular low-riding pushchairs could be exposing their babies to alarming levels of air pollution, finds a new study.

New research has found that the presence and severity of mild behavioral impairment (MBI) in cognitively healthy individuals is strongly associated with the presence of amyloid plaques deposits in the brain, a hallmark of Alzheimer's disease.

The existence of a magnetic field beyond 3.5 billion years ago is still up for debate.

A drug used for cancer therapy has shown promise in reversing kidney damage caused by systemic lupus erythematosus (SLE, or lupus), according to a Yale-led study published April 8 in the journal Science Translational Medicine.

A new analysis supports prior reports that people with sickle cell disease have lower rates of human immunodeficiency virus (HIV) infection, but follow-up cell studies did not reveal a mechanism to explain the reduced risk.

A new species of Triassic reptile from Brazil is a close cousin of a mysterious group called tanystropheids.

The Belle II experiment started about one year ago. The work deals with a new particle in the context of dark matter, which accounts for about 25 percent of the universe.

Amyloid is a key feature of Alzheimer's disease, but the accumulation of these sticky proteins may not be the only risk factor for developing Alzheimer's disease, according to a new study.

A new review summarizes evidence available from modelling studies that show how quarantining affects the spread of COVID-19. The studies included in the review consistently conclude that quarantine can play a role in controlling the spread of coronavirus SARS-CoV-2. While early implementation of quarantine and its combination with other public health measures may reduce spread of the disease, key...

A new modelling article, using data from Ontario, indicates that dynamic physical distancing and other measures could help maintain health system capacity and prevent intensive care units (ICUs) from becoming overwhelmed because of COVID-19, while allowing periodic psychological and economic breaks from restrictions.

Chloroquine, hydroxychloroquine and azithromycin are being used to treat and prevent COVID-19 despite weak evidence for effectiveness, and physicians and patients should be aware of the drugs' potentially serious adverse events, states a new review.

New research finds that 'fake news' inspires consumers to demand corrective action from companies -- even if the company is a victim of the fake news story. The study also supports the idea that most people feel they are better at detecting fake news than other people are.

Malaria is a leading killer of children worldwide, and new drugs are needed. New research reports encouraging early clinical results with a new compound.

The finding also could have important implications for a wide range of neurodegenerative diseases, such as Alzheimer's and Parkinson's.

Research suggests mature forests are limited in their ability to absorb 'extra' carbon as atmospheric carbon dioxide concentrations increase.

An international research team has mapped the interstellar magnetic field structure and interstellar matter distribution in the solar neighborhood.

A team has developed a new method to date archaeological pottery using fat residues remaining in the pot wall from cooking. The method means prehistoric pottery can be dated with remarkable accuracy, sometimes to the window of a human life span. Pottery found in Shoreditch, London proven to be 5,500 years old and shows the vibrant urban area was once used by established farmers who ate cow, sheep...

Someday, microbial cyborgs -- bacteria combined with electronic devices -- could be useful in fuel cells, biosensors and bioreactors. But first, scientists need to develop materials that not only nurture the microbes, but also efficiently and controllably harvest the electricity or other resources they make. Now, researchers have developed one such material that enabled them to create a...
