Cambridge researchers have shown that there are three different subtypes of severe pneumonia, helping to explain why some patients in intensive care units (ICUs) recover from the disease faster than others, while for others the disease can be life-threatening. Their findings could help inform personalized treatments in the future, ensuring each patient receives the most appropriate treatment. Pneumonia is the most common infectious cause of death worldwide, killing an estimated 2.5 million people annually. In severe cases, patients may be admitted to the ICU and require a ventilator. Six out of 10 infections managed in intensive care units are severe…

Scientists at the SETI Institute have completed a search for a possible technological signal coming from 3I/ATLAS, the third known interstellar object to transit our solar system. Researchers used the Allen Telescope Array (ATA) at Hat Creek Radio Astronomy Observatory in Northern California to scan a wide range of radio frequencies for evidence of extraterrestrial technology. As expected based on previous observations, they found no sign of an artificial signal, further supporting the conclusion that 3I/ATLAS is a natural comet-like object. First seen in July 2025, 3I/ATLAS is the third confirmed interstellar object ever observed to enter the solar system.…

A night without sleep increases markers of connectivity between brain cells, suggesting that sleep in humans may be important in restoring the brain’s cellular balance, according to research published June 23 in an open access journal. PLOS Biology By David Elmenhorst and colleagues at the Jülich Institute for Neuroscience and Medicine in North Rhine-Westphalia, Germany. Scientists have long wondered why humans and other animals need to sleep. One possible mechanism is that sleep is necessary to restore synaptic connections and homeostasis in the brain. Synapses (connections between brain cells) are strengthened during wakefulness. This increases the amount of energy required…

A new Rutgers study suggests that many of the seemingly endless and complex medical wait times can be avoided by recreating operations in a computer and testing countless potential improvements. research in Operations Research Annual Report Researchers at Rutgers Cancer Institute and Rutgers Business School have built a working computer simulation of the institute’s blood cancer clinic and describe how they used it to identify and fix bottlenecks that caused patients to wait up to three hours between check-in and treatment. Subsequent changes have reduced the turnaround time for blood tests in the lab from about 90 minutes to less…

Using artificial intelligence (AI), researchers found that image-based breast cancer risk scores from screening mammograms change over time and differ between women who develop cancer and those who do not, opening the door to a new era of dynamic breast cancer risk assessment.新しい研究は本日、 RadiologyJournal of the Radiological Society of North America (RSNA). Deep learning models can now generate breast cancer risk scores directly from screening mammograms, using the entire image rather than limited, predetermined features such as density. These models perform better than traditional risk models or breast density alone in estimating a woman’s 5-year breast cancer risk. Most women…

Triple-negative breast cancer (TNBC) is highly aggressive and difficult to treat. But a new paper by scientists at the Hackensack Meridian Center for Discovery and Innovation (CDI) and colleagues at Georgetown University’s Lombardi Comprehensive Cancer Center says the role of adipose tissue in cancer spread could help point to new understanding and treatments. Scientists have now demonstrated that fat tissue can be hijacked by tumor cells to launch itself and use adipomes, tiny extracellular vesicles released by fat tissue, to spread further into the body, outward from the breast and outward to other organs. This discovery could provide new strategies…

“There is a very urgent need to find ways to reduce the emissions that these backup generators emit into nearby communities,” said Associate Professor Damien Pitt, who conducted the research. To date, the operating rates of these backup generators are far below the operating rates allowed by Virginia law. “The really big problem is that the total amount of emissions allowed is 10 to 20 It’s many times larger than what’s currently being released,” Pitt said. That’s why Rep. John McAuliffe, a Democrat whose district in Northern Virginia is on the edge of the so-called data center array, introduced a…

The Ross procedure is a highly specialized option for aortic valve replacement, with long-term durability and excellent outcomes in a wide range of adult patients with aortic valvular disease. These are the results of a new groundbreaking study led by Ismail El Hammamsy, MD, world-renowned Mount Sinai cardiac surgeon and chief of aortic surgery at the Mount Sinai Health System, and published June 23 in the journal Ismail El Hammamsy, MD. Journal of the American College of Cardiology (Jack). This landmark publication represents the largest North American study ever conducted on the Ross procedure. The findings from this contemporary cohort…

When H5N1 avian influenza began infecting dairy cows in the United States in early 2024, veterinarians struggled to pinpoint the cause. The virus has been difficult to recognize because it behaves very differently in cattle than in other mammals. Rather than primarily infecting the lungs, H5N1 causes severe infections in the breasts, but has little effect on the respiratory system. Now, researchers at the University of Pittsburgh School of Public Health have uncovered the biological reason behind this unusual pattern. Their findings were; scientific progressfor the first time we have a detailed explanation of why avian influenza took such an…

Researchers have developed a chip-based metasurface biosensor that can detect traumatic brain injury (TBI) biomarkers at extremely low levels. With further development, this technology could one day allow doctors to quickly diagnose the aftermath of a head injury, guide treatment, and provide early warning of complications as they occur. Metasurfaces are ultra-thin materials patterned with tiny features that can manipulate light in ways that traditional lenses cannot. Coating the metasurface with antibodies that bind to specific target molecules allows those molecules to be detected using light. Although several biomarkers have been validated as indicators of traumatic brain injury, current…
