Srikanth Singamaneni and Barani Raman in the McKelvey School of Engineering developed technology to use nanoparticles to heat, manipulate cells in the brain and heart.

A new study of almost 12,000 Australians has found one-third of the adult population has experienced pure cybercrime during their lifetime, with 14% reporting this disruption to network systems in the past 12 months.With all forms of cybercrime already costing trillions every year globally, experts from the Australian Institute of Criminology (AIC) and Flinders University say the crimes involved substantial levels of personal victimisation including direct losses as well as the high cost of preventing future attacks.

The importance of aryl sulfides in biologically active compounds has led chemists to develop methods to synthesize them from carbon-sulfur bond forming reactions. The conventional reaction, however, uses thiols that are foul-smelling and toxic. Now, chemists from Waseda University, Japan, report a novel, thiol-free synthesis technique comprising a nickel-catalyzed aryl exchange between 2-pyridyl sulfide and aromatic esters, providing a versatile and inexpensive technology for both scientific and industrial applications.

A comprehensive new study led by researchers from Lawrence Berkeley National Laboratory (Berkeley Lab) quantifies what can be done to make buildings more energy efficient and flexible in granular detail by both time (including time of day and year) and space (looking at regions across the U.S.). The research team found that maximizing the deployment of building demand management technologies could avoid the need for up to one-third of coal- or gas-fired power generation.

A researcher from the University of Tsukuba, together with well-known development economists, conducted randomized trials of the System of Rice Intensification (SRI) agronomy method. Following SRI training of 5,486 Bangladeshi rice farmers, they compared trained and untrained farmers. The results showed compelling benefits for SRI's efficacy in increasing yield and profits, how it improves farming households' well-being, and its positive spillover effects in communities. This bolsters support for SRI's value, especially in the Global South.

Scientists from the Institut Pasteur, in collaboration with the French National Health Insurance Fund (CNAM), Ipsos and Santé publique France showed that the two-dose vaccination regimen of mRNA vaccines provides 88% protection against non-variant virus, 86% against the Alpha variant and 77% against the Beta variant. The results of this study were published in The Lancet Regional Health Europe on July 14, 2021

In the United States, climate change is controversial, which makes communicating about the subject a tricky proposition. A recent study by Portland State researchers Brianne Suldovsky, assistant professor of communication, and Daniel Taylor-Rodriguez, assistant professor of statistics, explored how liberals and conservatives in Oregon think about climate science to get a better sense for what communication strategies might be most effective at reaching people with different political ideologies.

A major challenge in cancer therapy is the adaptive response of cancer cells to targeted therapies. Although this adaptive response is theoretically reversible, such a reversal is hampered by numerous molecular mechanisms that allow the cancer cells to adapt to the treatment. A team (UNIGE/HUG) has used information theory, in order to objectify in vivo the molecular regulations at play in the mechanisms of the adaptive response and their modulation by a therapeutic combination.

Recently, metal halide perovskite solar cells (PSCs) have attracted world-wide interest due to their high power conversion efficiency of 25.5% and great potential in becoming a disruptive technology in the photovoltaic industry. Scientists in China summarized current challenges and strategies for the fabrication of PSCs by printing techniques. Moreover, the stability of perovskite solar modules has been discussed and analyzed.

St. Jude Children's Research Hospital scientists have shown that frailty contributes to neurocognitive decline in young adult survivors of childhood cancer.

Researchers are the first to model COVID-19 completion versus cessation in clinical trials using machine learning algorithms and ensemble learning. They collected 4,441 COVID-19 trials from ClinicalTrials.gov to build a testbed with 693 dimensional features created to represent each clinical trial. These computational methods can predict whether a COVID-19 clinical trial will be completed or terminated, withdrawn or suspended. Stakeholders can leverage the predictions to plan resources, reduce costs, and minimize the time of the clinical study.

A new study from Oregon State University found that infants born within 3 kilometers of oil and natural gas drilling facilities in Texas had slightly lower birthweights than those born before drilling began in their vicinity.

The parasites that cause severe malaria are well-known for the sinister ways they infect humans, but new research may lead to drugs that could block one of their most reliable weapons: interference with the immune response.

Regulatory T cells (Tregs) help control inflammation and autoimmunity in the body. Unfortunately, it has proven difficult to find the right molecular ingredients to induce stable iTregs. Now a new study reports that Vitamin C and TET proteins can work together to give Tregs their life-saving power.

Older adults may be slower to learn actions and behaviours that benefit themselves, but new research shows they are just as capable as younger people of learning behaviours that benefit others.

Imagine meeting a friend on the street, and imagine that with every step they take, your visual system has to process their image from scratch in order to recognize them. Luckily, our visual system is able to retain information obtained in motion, thereby presenting us with a consistent picture of our surroundings. These are the findings of a study conducted by SISSA, in collaboration with the Penn and KU Leuven and published in Nature Communications, which explains the neuronal underpinnings of this phenomenon.

Small increases in daily physical activity after receiving an implantable cardioverter defibrillator (ICD) were associated with decreases in hospitalizations and deaths among adults over age 65 with heart failure.For every 10 minutes a day of increased physical activity, there was a 1% lower risk of death and hospitalization.

Babies who were breastfed, even for a few days, had lower blood pressure at 3 years of age than children who had never been breastfed.Toddlers who had been breastfed had lower blood pressure regardless of their body mass index or their mothers' social, health or lifestyle factors.

Sweeping changes in marine nutrients may seem to be a likely consequence of increasing global temperatures; however, new research suggests that processes below the ocean surface could play a larger role than previously thought.

Smartphone gaming can be harmful to players who game to escape their negative mood and feelings of boredom, a new study has found.
