(Center of Diagnostics and Telemedicine) Center for Diagnostics and Telemedicine launched a new information resource: tele-med.ai. Attractive interface, convenient navigation, and all the most relevant information are the three pillars on which the concept of this site rests. The site is intended for heads of departments of radiation diagnostics, doctors of the departments of radiology, radiology, functional diagnostics and ultrasound, and radiologists and specialists in related fields.

For the first time, scientists have shown that the bacterium that causes the tick-borne disease anaplasmosis interferes with tick gene expression for its survival inside cells and to spread to a new vertebrate host. Girish Neelakanta of Old Dominion University and colleagues report these findings in a study published July 2nd in PLOS Genetics.

While scientists are trying to find a vaccine for COVID-19, the rabies virus continues to kill 59,000 people every year. But unlike COVID, a vaccine has existed for more than a century. Vaccinating dogs can stop the spread to humans, but systemic challenges make that easier said that done. In a new study, scientists where grassroots campaigns to stop rabies work-- and where they need to be coupled with large-scale efforts.

Lugano, Switzerland, 2 July 2020 - Artificial intelligence (AI) holds promise for enabling earlier detection of pancreatic cancer, which is crucial to saving lives. The potential of AI is showcased in a study to be presented at the ESMO World Congress on Gastrointestinal Cancer, 1-4 July 2020.

Researchers at Eindhoven University of Technology (TU/e), the Netherlands have developed a new method to convert gaseous, low-weight hydrocarbons into more complex molecules by illuminating the hydrocarbons with light in the presence of a suitable catalyst.

Spawning fish and embryos are far more vulnerable to Earth's warming waters than fish in other life stages, according to a new study, which uniquely relates fish physiological tolerance to temperature across the lifecycles of nearly 700 fish species.

For people infected by HIV in the subset of cases involving several variants of the virus, and for which disease progression is usually faster, a new modeling study suggests the number of infection-initiating viral variants is primarily determined by how long the source partner has been infected.

Free-flowing filaments of Uromodulin protect against urinary tract infections (UTIs) by duping potentially harmful bacteria to attach to their fishbone-like molecular architecture - rather than to sensitive urinary tract tissues - before being flushed out of the body during urination, researchers report.

In a study that takes another look at histones' origins, researchers report these proteins, known for DNA-packing, may have evolutionary roots in early life in helping to maintain the use of metals like copper - fundamental for biological processes, but which became toxic to eukaryotes as they adapted to global oxygenation.

Researchers have solved the mystery of why a species of bacteria that causes food poisoning can swim faster in stickier liquids, such as within guts.

University of Oregon chemists have made substantial gains in enhancing the catalytic water dissociation reaction in electrochemical reactors, called bipolar membrane electrolyzers, to more efficiently rip apart water molecules into positively charged protons and negatively charged hydroxide ions.

In a new meta-study, experts from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have published ground-breaking findings on the effects of climate change for fish stock around the globe.

Some people are better protected than others against urinary tract infections. This may be because their bodies produce more of a protein called uromodulin. An interdisciplinary research team has now found out exactly how this helper protein brings relief when nature calls and how this knowledge might benefit the treatment and prevention of these painful inflammations.

In an article published today in Science, a multidisciplinary research team from more than 10 universities and research institutes outlines how integrating a more diverse set of species and environments could enhance the biomedical research cycle.

Solar energy researchers are shining their scientific spotlight on materials with a crystal structure discovered nearly two centuries ago.

Incarceration and police discrimination may contribute to HIV, depression and anxiety among Black gay, bisexual and other sexual minority men, according to a Rutgers led study.

Neuroscientists describe for the first time how relationships between different odors are encoded in the brain. The findings suggest a mechanism that may explain why individuals have common but highly personalized experiences with smell, and inform efforts better understand how the brain transforms information about odor chemistry into the perception of smell.

New research from The University of Texas at Dallas suggests food deserts might be more prevalent in the U.S. than the numbers reported in government estimates. In a feasibility study published in the journal Frontiers in Public Health, scholars found that the methods used by the U.S. Department of Agriculture (USDA) to identify areas with low access to healthy food are often outdated and narrow in scope.

In a new study in rotifers (microscopic invertebrates), scientists tested the evolutionary fitness of older-mother offspring in several real and simulated environments, including laboratory culture, under threat of predation in the wild, or with reduced food supply. They confirmed that this effect of older maternal age, called maternal effect senescence, does reduce evolutionary fitness of the offspring in all environments, primarily through reduced fertility during their peak reproductive period.

Intrigued by how reflection changes images in subtle and not-so-subtle ways, a team of Cornell University researchers used artificial intelligence to investigate what sets originals apart from their reflections. Their algorithms learned to pick up on unexpected clues such as hair parts, gaze direction and, surprisingly, beards - findings with implications for training machine learning models and detecting faked images.

As many as 7% of moms-to-be use marijuana while pregnant, and that number is rising fast as more use it to quell morning sickness. But new research suggests such use could have a lasting impact on the fetal brain, influencing children's sleep for as much as a decade.

A University of California, Riverside, study that sought to determine barriers to health care among Spanish-speaking Latino farmworkers in rural communities has devised an innovative health care service delivery model that addresses many challenges these communities face: mobile health clinics that bring health care services to patients in their community spaces.

(National Research Council of Science & Technology) The Korea Institute of Machinery & Materials (KIMM) under the Ministry of Science and ICT developed a remote specimen collection robot that eliminates direct contact between medical personnel and patients.

(Kessler Foundation) 'For the second consecutive month, we are seeing indications that people with and without disabilities returned to work as businesses opened up,' said John O'Neill, Ph.D., director of employment and disability research at Kessler Foundation. 'However, keep in mind, these statistics are for the week of June 7th through 13th and thus do not reflect recent re-openings and closures of businesses as COVID-19 continues to affect the US,' he added.
