Lobachevsky University scientists have implemented a new variant of the metal-oxide memristive device, which holds promise for use in RRAM (Resistive Random Access Memory) and novel computing systems, including neuromorphic ones.

The microbiome of our ancestors might have been more important for human evolution than previously thought, according to a new study published in Frontiers in Ecology and Evolution. An adaptive gut microbiome could have been critical for human dispersal, allowing our ancestors to survive in new geographic areas.

One, two, three, four, five. One, two, three, four, five. Over and over and over. That's the dull routine of any researcher or student tasked with counting weed seeds. But just like technology has made many things in life faster and easier, relief may be coming for seed counters as well.

A team of researchers at the University of Arkansas, Auburn University and North Carolina State University set out to see if a piece of technology, called a computerized particle analyzer, can be used to count weed seeds. Their results are promising and show the analyzer accurately counts seeds.

WEST LAFAYETTE, Ind. - Security of embedded devices is essential in today's internet-connected world. Security is typically guaranteed mathematically using a small secret key to encrypt the private messages.

When these computationally secure encryption algorithms are implemented on a physical hardware, they leak critical side-channel information in the form of power consumption or electromagnetic radiation. Now, Purdue University innovators have developed technology to kill the problem at the source itself - tackling physical-layer vulnerabilities with physical-layer solutions.

The financial burden on health systems would drastically increase if new European expert guidelines for cholesterol-lowering treatment were implemented, according to a new simulation study by researchers at Karolinska Institutet in Sweden, published in the European Heart Journal. The findings highlight an urgent need for cost-effectiveness analysis given the current cost of the proposed treatment for very high-risk patients, the researchers say.

U.S. women who take prescription opioids are no less likely to receive key cancer screenings when compared to women who are not prescribed opioids. Researchers at the University of California, Davis analyzed data from a nationally representative sample of 53,982 women in the United States. Findings revealed that women who are prescribed opioids were more likely to receive breast, cervical, and colorectal cancer screenings for the simple fact that they are frequent users of the health care system.

Patients taking warfarin to reduce the risk of stroke and pulmonary embolisms are often advised to take the medication in the evening. But does time of day really matter? A new study shows evidence that morning versus evening dosing has insignificant bearing on how long the drug provides the most benefit for preventing adverse health events. Two hundred and seventeen adults who regularly used warfarin in the evenings were randomized to the trial, with about half switching to morning medication use for seven months.

FEBRUARY 18, 2020, NEW YORK -- A Ludwig Cancer Research study has identified a mechanism by which regulatory T cells, which suppress immune responses, adapt their metabolism to thrive in the harsh microenvironment of the tumor. This mechanism, the study finds, is exclusively engaged by regulatory T cells (Tregs) that reside in tumors and could be disrupted to selectively target such Tregs and boost the effects of cancer immunotherapy.

Climate change is being felt in a corner of the world different from where one might expect: Wall Street, where some of the biggest investors are starting to take action.

INDIANAPOLIS -- An Indiana University cancer researcher has identified eight new genomic regions that increase a person's risk for skin cancer.

Exposing teeth to excessive fluoride alters calcium signaling, mitochondrial function, and gene expression in the cells forming tooth enamel--a novel explanation for how dental fluorosis, a condition caused by overexposure to fluoride during childhood, arises. The study, led by researchers at NYU College of Dentistry, is published in Science Signaling.

Researchers at North Carolina State University have demonstrated a new, green technology for both accelerated screening and retrieving "switchable" solvents used in green chemistry applications. The new approach makes the screening process hundreds of times faster and drastically accelerates the rate at which solvents can be retrieved from solution.

Let's assume we are dancing on a meadow, quickly spinning about our own axis. At some point we hop on a rotating carousel. We may end up hurting ourselves when both rotations add up and angular momentum is transferred. Are similar phenomena also present in quantum mechanical systems?

Breastfeeding affects infant growth and, researchers have found, helps prevent obesity, both in childhood and later in life. However, the components of breast milk responsible for these beneficial effects remain mostly a mystery.

Human milk is an elaborate blend of proteins, fats, minerals and vitamins, plus complex sugar molecules called human milk oligosaccharides, or HMOs. There are approximately 150 types of HMOs. Like thumb and tongue prints, the combination and concentration of HMOs is unique to each nursing mother.

A team of physicists at the University of Sussex has successfully developed the first nonlinear camera capable of capturing high-resolution images of the interior of solid objects using terahertz (THz) radiation.

Led by Professor Marco Peccianti of the Emergent Photonics (EPic) Lab, Luana Olivieri, Dr Juan S. Totero Gongora and a team of research students built a new type of THz camera capable of detecting THz electromagnetic waves with unprecedented accuracy.
