Researchers have mapped in fine detail the genetic changes malaria parasites go through as they prepare to infect people.

Adults with obsessive-compulsive disorder (OCD) were more than three times as likely as those without the disorder to have an ischemic stroke later in life. Adults with OCD should maintain a healthy lifestyle, including not smoking, exercising, and managing a healthy weight, to help prevent stroke.Health care professionals should closely monitor patients with OCD for increased risk of ischemic stroke.

A digital tool that will make it cheaper, safer and faster to develop new medicines is being rolled out by scientists from the University of Bath in the UK.

Nearly three years after the Trump administration's "Zero Tolerance" policy went into effect, more than 445 children remain separated from their families, largely due to insufficient identifying paperwork and U.S. immigration officials' failures to plan, track and reunite separated families.

Urgent investment in new tools is needed to address major global losses of wheat crops which cost £22 billion per year.

If a ban were introduced on the sale of new petrol and diesel cars, and they were replaced by electric cars, the result would be a great reduction in carbon dioxide emissions. That is the finding of new research from Chalmers University of Technology, Sweden, looking at emissions from the entire life cycle - from manufacture of electric cars and batteries, to electricity used for operation.

A new study has found that online news tools can be a useful strategy for reaching broad and diverse populations during emerging outbreaks, providing a quick and easy way to capture data on what is happening in the community at large rather than people hospitalized with the disease. "Capturing COVID-like Symptoms At-Scale using Banner Ads: A Novel Survey Methodology Pilot using an Online News Platform" is published in the Journal of Medical Internet Research (JMIR).

A new longitudinal study examined the relation between sleep, classroom behavior, and academic achievement scores among primarily Black children growing up in historically disinvested neighborhoods. Disinvested refers to neighborhoods in which public and private funding, city services, or other necessary resources have been denied or withheld, and which are often segregated along racial and economic lines as a result. The findings showed that sleep is related to observed classroom behavior and may predict future academic achievement.

A new longitudinal study examined bidirectional relationships between home literacy environment and children's progress in learning to read between grades 1 and 3. Results show that parents adjust their reading activities with their children over time, taking into account the level of difficulty the children are having in learning to read. These findings raise the important possibility that teachers could give more specific guidance to parents to help shape the home literacy environment according to children's progress in learning to read.

Antibodies aren't the only immune cells needed to fight off COVID-19 -- T cells are equally important and can step up to do the job when antibodies are depleted, suggests a new Penn Medicine study of blood cancer patients with COVID-19 published in Nature Medicine.

The puzzle of how internal OH- impurities affect photon energy upconversion has been quantitatively disentangled through combining internal OH- content manipulation in nanocrystals, spectroscopy and Monte Carlo simulation. The exponential relationship between upconversion luminescence intensity and the quantity of internal OH- was discovered. The work not only paves the way to pursuit new structures and/or doping patterns for higher upconversion efficiency, but also provides a new method for studying the internal defects of phosphors.

To survive in a reduced pH environment, marine organisms have to adjust their physiology which, at the molecular level, is achieved by modifying the expression of genes. The study of such changes in gene expression can aid in revealing the adaptive mechanisms of life under predicted future ocean acidification conditions.

A group led by Prof. ZHANG Suojiang from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences (CAS) recently found that ionophobic electrodes can boost energy storage performance.

Current best practices for encouraging more female students to pursue degrees in economics may actually have the opposite effect and worsen gender disparities in the field, a recent study from Oregon State University found.

Researchers from the National University of Singapore have found a way to predict if ovarian cancer patients will be resistant to chemotherapy. By using "automated" microscopy, they identified a protein that indicates the resistance of ovarian cancer cells to platinum chemotherapy. This breakthrough could improve the survival rate of ovarian cancer patients, as other treatments may be administered early.

Different from small molecules, polymer will fold into lamellar crystals during crystallization and further assemble into lamellar stacks.

With global warming decreasing the size of New Zealand's alpine zone, a University of Otago study found out what this means for our altitude-loving kea.

Poor sleep impacts the risk of long-term cognitive decline in Hispanic/Latino middle aged and older adults differently than it does in non-Hispanic adults, according to research led by University of Miami Miller School of Medicine neurology faculty and the largest long-term study of US Hispanic/Latinos to date.

Each city has its own unique microbiome, a "fingerprint" of viruses and bacteria that uniquely identify it, according to a new study from an international consortium of researchers that included a team from the University of Maryland School of Medicine (UMSOM). The international project, which sequenced and analyzed samples collected from public transit systems and hospitals in 60 cities around the world, was published today in the journal Cell.

Half a billion tonnes of carbon emissions could be cut from Earth's atmosphere by improved management of peatlands, according to research partly undertaken at the University of Leicester.
