MINNEAPOLIS – How are you sleeping? A new study has found the transition from daylight saving time to standard time, when one hour is gained overnight, was associated with a brief increase in sleep disorders such as difficulty going to sleep or staying asleep, but there was no such association when an hour is lost in the change from standard time to daylight saving time. The study is published in the May 3, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. It also found a small difference in the amount of sleep people get depending ...

When Doc Brown fed his DeLorean food scraps in Back to the Future as fuel, it seemed like crazy science fiction. Now science is taking over that fiction as UBC Okanagan researchers are looking at the potential of using fruit waste—both solid and leachate—to power fuel cells. While the energy extracted from food scraps still pales in comparison to solar or wind power, researchers are working towards purifying and improving the energy output of discarded food, particularly fruit waste—an item that is in abundance in the agricultural belt of the Okanagan Valley. According ...

MINNEAPOLIS/ST. PAUL (05/03/2023) — Published in the peer-reviewed journal Alcohol: Clinical & Experimental Research, University of Minnesota Medical School researchers found people with an anxiety or major depression disorder experience greater alcohol use disorder symptoms and problems in comparison to people without those disorders — even at the same levels of drinking. This finding might help to explain why those who develop an anxiety or mood disorder are at heightened risk ...

Researchers at West Virginia University have uncovered critical data showing bariatric surgery as a treatment method for patients with nonalcoholic fatty liver disease has a significant impact on improving clinical outcomes. The study, led by Dr. Shailendra Singh, included thousands of patients diagnosed with NAFLD, a condition that is seeing an upsurge and contributes to multiple other afflictions.  While bariatric surgery has long been associated with reducing cardiovascular disease and death in patients with obesity, the research team set out to explore whether the ...

Two-photon microscopy (TPM) has revolutionized the field of biology by enabling researchers to observe complex biological processes in living tissues at high resolution. In contrast to traditional fluorescence microscopy techniques, TPM makes use of low-energy photons to excite fluorescent molecules for observation. This, in turn, makes it possible to penetrate the tissue much more deeply, and ensures that the fluorescent molecules, or fluorophores, are not permanently damaged by the excitation laser.  However, some biological processes are simply too fast to be recorded, even with state-of-the-art TPMs. One of the design parameters that limits the performance of a TPM is ...

Water isn’t just a universal solvent that remains unaffected by its interactions. New publications from North Carolina State University show that water can change its solubility characteristics depending upon what it interacts with. Specifically, when water interacts with cellulose, it can stack in layered shells to control chemical reactions within, and physical properties of, the material. The work has implications for more sustainable and efficient design of cellulose-based products. “Cellulose is the world’s most abundant biopolymer, and it’s used in applications ...

Inside a lab, scientists marvel at a strange state that forms when they cool down atoms to nearly absolute zero. Outside their window, trees gather sunlight and turn them into new leaves. The two seem unrelated—but a new study from the University of Chicago suggests that these processes aren’t so different as they might appear on the surface. The study, published in PRX Energy on April 28, found links at the atomic level between photosynthesis and exciton condensates—a strange state of physics that allows energy to flow frictionlessly ...

WASHINGTON — Researchers have developed a new high-speed way to detect the location, size and category of multiple objects without acquiring images or requiring complex scene reconstruction.
