New research suggests people who are scheduled for certain medical procedures should stop taking popular weight loss drugs in the days or weeks prior to avoid complications.
An enzymatic cocktail can kill a variety of mycobacterial species of bacteria, including those that cause tuberculosis.
A new image from the Event Horizon Telescope (EHT) collaboration has uncovered strong and organized magnetic fields spiraling from the edge of the supermassive black hole Sagittarius A* (Sgr A*). Seen in polarized light for the first time, this new view of the monster lurking at the heart of the Milky Way Galaxy has revealed a magnetic field structure strikingly similar to that of the black hole at the center of the M87 galaxy, suggesting that strong magnetic fields may be common to all black holes.
Researchers have discovered a safer and more efficient technique for testing new drugs while they are in development.
Researchers found that the double-lobed object, which is officially named Kuiper Belt Object 486958 Arrokoth and resembles a snowman, may have ancient ices stored deep within it from when the object first formed billions of years ago.
Researchers are enhancing immunotherapy effects against malignant tumors by developing and validating patent-ending poly (lactic-co-glycolic acid), or PLGA, nanoparticles modified with adenosine triphosphate, or ATP.
Researchers say they have discovered that the protein puromycin-sensitive aminopeptidase (NPEPPS) plays a role in regulating response to platinum chemotherapy in patients with bladder cancer.
With two-thirds of children in the U.S. failing to meet national physical activity guidelines, kinesiologistshave been looking at the impact of the family dog on the exercise habits of kids. Could having a canine best friend get kids on their feet and help bring them more in line with the minimum recommendation of 60 minutes of moderate to vigorous physical activity every day?
Floods affect more people worldwide than any other natural hazard, causing enormous damage that is expected to increase in a warming world. However, people and decision-makers in vulnerable regions are often unwilling to prepare for exceptionally severe events because they are difficult to imagine and beyond their experience.
Evolutionary biologists have unearthed a new species of tiger beetle, deemed Eunota houstoniana, honoring the Houston region where it predominantly resides.
The couple that drinks together might live longer together, too, says a University of Michigan researcher.
From pacemakers to neurostimulators, implantable medical devices rely on batteries to keep the heart on beat and dampen pain. But batteries eventually run low and require invasive surgeries to replace. To address these challenges, researchers have devised an implantable battery that runs on oxygen in the body. The study shows in rats that the proof-of-concept design can deliver stable power and is compatible with the biological system.
Researchers have discovered the first species pollinated by sap beetles in the genus Pandanus, a group of palm-like plants native to the tropics and subtropics of Africa and Eurasia. The discovery overturned the long-held belief that these plants were pollinated by wind. The researchers also found that fragrant screw pines' male and female flowers produced heat at night stably, making them the first such species in the family Pandanaceae.
Engineers have developed a novel method for manufacturing CAR T cells, one that takes just 24 hours and requires only one step, thanks to the use of lipid nanoparticles (LNPs), the potent delivery vehicles that played a critical role in the Moderna and Pfizer-BioNTech COVID-19 vaccines.
Scientists captured images showing the development of turbulence as a Coronal Mass Ejection (CME) interacted with the ambient solar wind in the circumsolar space.
Engineers have uncovered an unexpected pattern in how neural networks -- the systems leading today's AI revolution -- learn, suggesting an answer to one of the most important unanswered questions in AI: why these methods work so well. The result not only illuminates the inner workings of neural networks, but gestures toward the possibility of developing hyper-efficient algorithms that could classify images in a fraction of the time, at a fraction of the cost.
In a remarkable discovery, whole milk powder manufactured in New Zealand in 1907 and transported to Antarctica with explorers seeking the South Pole was unveiled after more than a century. The find has allowed dairy researchers to answer the question: Is the milk we enjoy today different from the milk consumed in previous generations? Now, a new comparative study has peered back in time to demonstrate that -- despite advancements in selective breeding and changes to farm practices -- milk of the past and milk today share more similarities than differences and are still crucial building blocks of human nutrition.
Those with aging immune systems struggle to fight off novel viruses and respond weakly to vaccination. Researchers were able to revitalize the immune system in mice.
The Antarctic Circumpolar Current plays an important part in global overturning circulation, the exchange of heat and CO2 between the ocean and atmosphere, and the stability of Antarctica's ice sheets. An international research team has now used sediments taken from the South Pacific to reconstruct the flow speed in the last 5.3 million years. Their data show that during glacial periods, the current slowed; during interglacials, it accelerated. Consequently, if the current global warming intensifies in the future, it could mean that the Southern Ocean stores less CO2 and that more heat reaches Antarctica.
Dedicated memory tests on smartphones enable the detection of 'mild cognitive impairment', a condition that may indicate Alzheimer's disease, with high accuracy.
