WASHINGTON — For the first time, researchers have shown that 3D-printed polymer-based micro-optics can withstand the heat and power levels that occur inside a laser. The advance enables inexpensive compact and stable laser sources that would be useful in a variety of applications, including the lidar systems used for autonomous vehicles. “We significantly reduced the size of a laser by using 3D printing to fabricate high-quality micro-optics directly on glass fibers used inside of lasers,” said research team leader Simon Angstenberger from the 4th Physics Institute at University of Stuttgart ...

PHILADELPHIA—(Dec. 13, 2023)—Wistar researchers successfully tested a simple intervention that could unlock greater anti-tumor power in therapies that use T cells — an approach known as “cell-based therapy,” which uses specially designed T cells to fight cancer. Led by Dr. Hildegund C.J. Ertl — a professor in The Wistar Institute’s Vaccine & Immunotherapy Center — the team has proven an exciting concept: that the common cholesterol drug fenofibrate can boost T cells’ ability to destroy human tumors, as described in their new paper, “Treatment ...

This holiday season brings surprising news about your Christmas tree. Scientists just discovered that globally, trees growing in wetter regions are more sensitive to drought. That means if your tree hails from a more humid clime, it’s likely been spoiled for generations. Scientists have long debated whether arid conditions make trees more or less resilient to drought. It seems intuitive that trees living at their biological limits will be most vulnerable to climate change, since even just a little extra stress could tip them past the brink. On the other hand, these populations have adapted to a harsher setting, so they might be more capable of withstanding a drought. According ...

URBANA, Ill. — When a sweet corn breeder reached out in 2021 to report severe injury from the herbicide tolpyralate, Marty Williams hoped it was a fluke isolated to a single inbred line. But two years later, after methodical field, greenhouse, and genetic testing, his new Pest Management Science study not only confirms sensitivity to tolpyralate in 49 sweet corn and field corn lines, but also reveals a new genetic vulnerability that may affect corn more generally. Tolpyralate is a relatively new ...

Based on this idea, they have developed a single-dose, dry-powder, inhalable vaccine platform using nano-micro composite multilevel structures, which has been successfully prepared in the laboratory, and the vaccine has been shown to be effective in blocking respiratory viral infection and transmission in animal models. This platform holds great promise for combating future emerging and epidemic infectious diseases. This ...

Cannabis use for medicinal or recreational purposes is now permitted is most states in the U.S. Many of the products sold in dispensaries contain delta-9-tetrahydrocannabinol (better known as “THC”), and are thus classified as Schedule I drugs, making them illegal under federal law. However, there is a parallel market for products derived from hemp—defined as cannabis containing less that 0.3 percent THC—spurred in part by the passage of the 2018 Farm Bill, which removed hemp-derived cannabinoids from the federal Controlled Substances Act. A new U-M study published in JAMA Network Open examines past-year use of some of these hemp-derived ...

PHILADELPHIA— New research reveals that neurons in the preoptic hypothalamus—the region of the brain that regulates sleep and body temperature—are rhythmically activated during non-rapid eye movement sleep (NREM). Stress activates these brain cells out of turn, causing “microarousals,” that interrupt sleep cycles and decrease the duration of sleep episodes, according to research from Perelman School of Medicine at the University of Pennsylvania, published today in Current Biology. While our bodies are at rest when we are asleep, ...
