Millions of people around the world use acid suppressants called proton pump inhibitors for conditions like heartburn, gastritis and stomach ulcers. Researchers at Karolinska Institutet in Sweden now report that how the long-term use of these drugs could increase the risk of developing dementia. Their results are published in the journal Alzheimer's & Dementia.

The brain has a powerful ability to remember and connect events separated in time. And now, in a new study in mice published today in Neuron, scientists at Columbia's Zuckerman Institute have shed light on how the brain can form such enduring links.

Ichthyosaurs were marine reptiles during the time of the dinosaurs, and scientists don't know much about their ancestry. But by CT-scanning the fossil of one of the first ichthyosaurs, scientists discovered pebble-shaped teeth hidden in its short snout. These strange teeth, probably used for crushing the shells of snails and clam-like bivalves, help illuminate the ways that early ichthyosaurs filled different roles in Triassic marine ecosystems.

Researchers at Washington University School of Medicine in St. Louis found that gene therapy in mice helped build strength and significant muscle mass quickly, while reducing the severity of osteoarthritis. The gene therapy also prevented obesity, even when the mice were fed a high-fat diet.

Some plants, like soybean, are known to possess an innate defense machinery that helps them develop resistance against insects trying to feed on them. However, exactly how these plants recognize signals from insects has been unknown until now. In a new study, scientists in Japan have uncovered the cellular pathway that helps these plants to sense danger signals and elicit a response, opening doors to a myriad of agricultural applications.

Temperature and latitude do not appear to be associated with the spread of coronavirus disease 2019 (COVID-19), according to a study of many countries published in CMAJ (Canadian Medical Association Journal), but school closures and other public health measures are having a positive effect.

MERS, which struck South Korea in a 2015 outbreak, was caused by a coronavirus--the same family of viruses that is responsible for COVID-19. Recently, a Korean research team announced that it had developed a new vaccine platform using RNA-based adjuvants for the MERS coronavirus. The research team successfully conducted an experiment on nonhuman primates. It is expected that the new vaccine platform will soon be applicable to the development of a COVID-19 vaccine, an urgent global health priority.

The International Telecommunication Union (ITU) is a United Nations Organization agency commissioned to regulate international telecommunications between different operating administrations and businesses. Pursuant to specific recommendations by this organization, on 1 July, standard Y.3172, an architecture for machine learning in future networks (5G and beyond), was approved for telecommunications networks.

ITMO University researchers together with their colleagues from France and the USA have demonstrated how a femtosecond laser can be used to tune the structure and nanocomposite properties for titanium dioxide films filled with gold nanoparticles.

Hematopoietic stem cells from a healthy donor can help patients suffering from acute leukemia. However, the side effects of therapies are often severe. A group of researchers led by the University of Zurich have now shown how human healthy and cancerous hematopoietic stem cells can be more selectively eliminated using immunotherapy instead of chemotherapy in mice. The aim is to test the new immunotherapy in humans as soon as possible.

With a discovery that could rewrite the immunology textbooks, an international group of scientists, including the teams of Bart Lambrecht, Martin Guilliams, Hamida Hammad, and Charlotte Scott (all from the VIB-UGent Center for Inflammation Research) identified a new type of antigen-presenting immune cell.

Scientists at Nanyang Technological University, Singapore (NTU Singapore) have developed a green way to create chitin, by using two forms of food waste - prawn shells and discarded fruit - and fermenting them.

It's a common phenomenon we know from cracked sneakers and burst tyres: worn-out materials can cause anything from mild annoyance to fatal accidents. But while fatigue is well understood in synthetic materials, we know much less about such processes in mammalian tissue. An international team led by HITS researchers has shown that mechanical stress can similarly deteriorate collagen tissue. The findings might help to advance material research and biomedicine.

A protein shredder that occurs in cell membranes of brain cells apparently also indirectly regulates the fat metabolism. This is shown by a recent study by the University of Bonn. The shredder, known as gamma-secretase, is considered a possible target for drugs against cancer and Alzheimer's disease. However, the results suggest that such agents may have long-range effects that need to be watched closely. The study has now been published in "Life Science Alliance".

Lipids are essential building blocks of cell membranes, which control the exchange of substances and energy between a cell and its environment. Developed at the Moscow Institute of Physics and Technology, a new open-source software tool PCAlipids aims to analyze lipid behavior.

Scientists have successfully developed a new technique to reliably grow crystals of organic soluble molecules from nanoscale droplets, unlocking the potential of accelerated new drug development.

An international team has discovered an effective method for controlling the frequency of confined light at the nanoscale in the form of phonon polaritons (light coupled to vibrations in the crystal). The results have now been published in Nature Materials.

Given the rapid spread of COVID-19 and its relatively high mortality, filling the gap for coronavirus-specific drugs is urgent.

The Monte Conca cave system in Sicily is showing signs of being altered by pollution from above.

Computerized tomography (CT) is one of the most effective medical tests for analysing the effects of many illnesses, including COVID-19. An international team has developed a new method that improves the quality of the images obtained from CT scans. The algorithm, tested on simulated data, enables them to distinguish different body's tissue types better and opens the door to lowering the doses of radiation to which patients are exposed during this type of test.

A two-week course of antiviral therapy with interferon beta-1b plus lopinavir-ritonavir and ribavirin, started within 7 days of showing COVID-19 symptoms, is safe and more effective at reducing the duration of viral shedding than lopinavir-ritonavir alone in patients with mild to moderate illness, according to the first randomized trial of this triple combination therapy involving 127 adults (aged 18 and older) from six public hospitals in Hong Kong.

The most extensive system of haze layers ever observed in the solar system have been discovered and characterised on the planet Saturn.

Evidence continues to mount that the Neandertals, who lived in Europe and Asia until about 40,000 years ago, were more sophisticated people than once thought. A new study from UC Davis shows that Neandertals chose to use bones from specific animals to make a tool for specific purpose: working hides into leather.

A study at Columbia University Mailman School of Public Health found that black subjects who were exposed to highly segregated neighborhoods in young adulthood exhibited worse performance in cognitive skills in mid-life. This outcome may explain black-white disparities in dementia risk at older age.

Photosynthetic systems in nature transport energy very efficiently towards a reaction center, where it is converted into a useful form for the organism. Scientists have been using this as inspiration to learn how to transport energy efficiently in, for example, molecular electronics. Physicist Richard Hildner from the University of Groningen and colleagues have investigated energy transport in an artificial system made from nanofibres. The results were published in the Journal of the American Chemical Society.

A new global simulation model offers the first long-term look at how urbanization -- the growth of cities and towns--will unfold in the coming decades. The research team projects the total amount of urban areas on Earth can grow anywhere from 1.8 to 5.9-fold by 2100, building approximately 618,000 square miles.

As interest in the application of plasma medicine -- the use of low-temperature plasma (LTP) created by an electrical discharge to address medical problems -- continues to grow, so does the need for research advancements proving its capabilities and potential impacts on the health care industry. Across the world, many research groups are investigating plasma medicine for applications including cancer treatment and the accelerated healing of chronic wounds, among others.

In the ongoing struggle to address health care disparities in rural communities across the US, a recent study found that the perfect partner may be hiding in plain sight. The grange, founded in 1867, is a community-based organization that is likely familiar to anyone who's spent time in a small town. In addition to political advocacy on behalf of farmers, the grange's missions around community and family also align closely with the goals of public health.

Although the clinical symptoms of SARS, H1N1, MERS, EVALI, and COVID-19 may be nonspecific, some characteristic imaging findings are emerging, says the American Journal of Roentgenology (AJR). Careful evaluation of the distribution, lung zone preference, and symmetry of the abnormalities with an eye for a few unique differentiating imaging features can allow radiologists to offer a narrower differential diagnosis in pediatric patients, leading to optimal patient care.
