“Space weather can impact systems that use IT for critical functions and everyday processes,” James Spann, a senior scientist at the Office of Space Weather Observations at the U.S. National Oceanic and Atmospheric Administration’s (NOAA) National Environmental Satellite, Data, and Information Service (NESDIS) department, told Space.com in an email. “These space weather impacts can have the same symptoms as a cyberattack, where systems will be brought down, or lockup, or transmit erroneous information.”

NESDIS oversaw a tabletop space weather exercise conducted in May 2024, the first such drill testing the U.S. preparedness for a major solar storm. Results of the exercise, which brought together 35 US government agencies, were published in a report in April.

In one of the simulations during the exercise, NOAA and the U.S. Air Force reported a severe solar flare and radio burst, but another federal department or agency “reported contradictory information, suggesting that the radio and communications disruptions were possibly the result of a cyberattack,” according to the report. Above all, it showed the need for effective communication following such events.

Wearable technologies are revolutionizing health care, but design limitations in adhesive-based personal monitors have kept them from meeting their full potential.

A new University of Arizona study, published in Nature Communications, describes a longer-lasting, 3D-printed, adhesive-free wearable capable of providing a more comprehensive picture of a user’s .

The device, which measures and emissions of gases, continuously tracks and logs associated with dehydration, metabolic shifts and stress levels.

Irritable bowel syndrome (IBS) is a prevalent and debilitating gastrointestinal disorder affecting approximately 5%–10% of the global population. Characterized by abdominal pain, bloating, and altered bowel habits, IBS imposes a significant burden on quality of life and health care systems worldwide.

Despite its prevalence, the exact pathogenesis of IBS remains elusive, and effective prevention strategies are lacking. Di Liu and colleagues conducted a comprehensive Mendelian randomization (MR) study—an approach that uses genetic variants as instrumental variables to infer causality.

The study integrates Mendelian randomization (MR) and multiresponse MR (MR2) analyses to distinguish genuine causal relationships from shared or spurious associations. The research is published in the journal eGastroenterology.

A new study led by researchers from Michigan State University, Yale University and Johns Hopkins University reveals that ransomware attacks—which involve a hacker putting encryption controls into a file and then demanding a ransom to unlock the files—have become the primary driver of health care data breaches in the United States, compromising 285 million patient records over 15 years.

Published May 14 in JAMA Network Open, the study provides the first comprehensive analysis of ransomware’s role in health care breaches across all entities covered by privacy laws—hospitals, physician practices, and data clearinghouses—from 2010 to 2024.

“Ransomware has become the most disruptive force in health care cybersecurity,” said John (Xuefeng) Jiang, Eli Broad Endowed Professor of accounting and in the MSU Broad College of Business and lead author of the study. “Hospitals have been forced to delay care, shut down systems and divert patients—all while sensitive patient data is held hostage.”

Current dental implants can work well, but they’re not perfect. They don’t attach to bones and gums in the same way that real teeth do. And around 20% of people who get implants end up developing an infection called peri-implantitis, which can lead to bone loss.

It is all down to the microbes that grow on them. There’s a complex community of microbes living in our mouths, and disruptions can lead to infection. But these organisms don’t just affect our mouths; they also seem to be linked to a growing number of disorders that can affect our bodies and brains. If you’re curious, read on.

The oral microbiome, as it is now called, was first discovered in 1670 by Antonie van Leeuwenhoek, a self-taught Dutch microbiologist. “I didn’t clean my teeth for three days and then took the material that had lodged in small amounts on the gums above my front teeth … I found a few living animalcules,” he wrote in a letter to the Royal Society at the time.

Scientists have developed a dual-laser Brillouin optical correlation-domain reflectometry (BOCDR) system that uses two frequency-modulated lasers. By scanning the relative modulation phase between the pump and reference lasers, the setup measures strain and temperature all along an optical fiber. In a proof-of-concept test on a 13-meter silica fiber, the team recorded Brillouin gain spectra (BGS) at only about 200 MHz—over 50 times lower than the usual 11 GHz band.

The research was published in the Journal of Physics: Photonics on April 25, 2025.

“The dual-laser approach makes BOCDR equipment simpler, more cost-effective, and easier to deploy, giving engineers a practical tool for long-term structural health monitoring, factory process control, and many other sensing tasks,” said senior author Associate Professor Yosuke Mizuno of Yokohama National University.

Biomarkers used to predict heart failure risk in the general population may be ineffective for assessing risk after pregnancies complicated by hypertension or diabetes, according to a study published in JAMA Cardiology.

Several adverse pregnancy outcomes, including preeclampsia and gestational , have been linked to long-term heart health risks for , said Priya Freaney, MD, ‘22 GME, assistant professor of Medicine in the Division of Cardiology, who was first author of the study.

“We know that features of complicated pregnancies can impact a woman’s heart disease risk decades later,” Freaney said. “It’s important for us to have some way to track and screen the patients that have pregnancy complications to further clarify if someone’s on a high-risk path toward and help bring their risk down with aggressive screening, prevention or early implementation of therapies.”

A multi-institutional collaboration of synthetic biology research centers in China has developed a genetically engineered strain of Vibrio natriegens capable of bioremediating complex organic pollutants, including biphenyl, phenol, naphthalene, dibenzofuran, and toluene, in saline wastewater and soils.

Complex are prevalent in industrial wastewater generated by petroleum refining and chlor-alkali processing. Due to their and resistance to natural degradation, these compounds persist in marine and saline environments, posing ecological risks and potential threats to public health.

Microbial bioremediation methods typically use consortia of wild-type bacterial strains, yet these organisms demonstrate limited capacity to degrade complex pollutant mixtures. Elevated salinity levels further inhibit bacterial activity, diminishing bioremediation efficacy in industrial and marine wastewater. Developing capable of degrading pollutants while tolerating saline conditions remains a critical challenge.
