An ocean in your brain: Interacting brain waves key to how we process information
For years, the brain has been thought of as a biological computer that processes information through traditional circuits, whereby data zips straight from one cell to another. While that model is still accurate, a new study shows that there's also a second, very different way that the brain parses information: through the interactions of waves of neural activity. The findings help researchers better understand how the brain processes information. Fri, 22 Apr 2022 16:15:27 EDT

Less prostate cancer screening reduces overdiagnosis but may miss aggressive cases
Over the past 15 years, public health authorities have downgraded recommendations for the prostate-specific antigen (PSA) test as a screening tool to reduce the overdiagnosis and overtreatment of men with low-grade prostate cancer. Now, researchers have found that while these efforts have been effective, the incidence of higher-grade disease and metastasis at diagnosis have risen. Fri, 22 Apr 2022 11:47:45 EDT

Establishment of a pancreatic cancer animal model using the pancreas-targeted hydrodynamic gene delivery method
Pancreatic cancer has a significantly poor prognosis; therefore, the development of effective treatments is an unmet clinical need. The major drawback in this field was the lack of useful model animals, which delayed the establishment of markers for early diagnosis and therapeutic options. The research group established an effective carcinogenesis method with wild-type rats by selectively introducing oncogenes into the pancreas, using the pancreas-targeted hydrodynamic gene delivery method that has been developed by the group.

Flexible electronics get brighter
Scientists have fabricated a flexible material that lights up brightly when stretched and/or when an electric field is applied. The results show promise for the development of bright, sustainable, stretchable devices for use, for example, as interactive skin displays and in soft robotics. Fri, 22 Apr 2022 09:43:23 EDT

Understanding arteriosclerosis: How blood vessels restructure under pressure
Hypertension, a very common condition worldwide, can lead to arteriosclerosis through alterations in the structure of blood vessel walls known as 'vascular remodeling.' In a recent study, an international team of scientists unveiled a molecular pathway for the development of arteriosclerosis for the first time. This could pave the way to better medication for preventing and treating hypertension and arteriosclerosis. Fri, 22 Apr 2022 09:43:20 EDT

New self-cleaning optical fiber can help in monitoring environment and diagnosing cancer
Researchers have successfully developed a novel optical fiber design allowing the generation of rainbow laser light in the molecular fingerprint electromagnetic region. This new optical fiber with a self-cleaned beam can help in developing applications to, for example, tagging pollutants, cancer diagnostics, environmental monitoring, and food control.

Water processing: Light helps degrade hormones
Micropollutants in water often are hormones that accumulate in the environment and may have negative impacts on humans and animals. Researchers have now developed a process for the photocatalytic degradation of these pollutants when they flow through polymer membranes. Irradiation with light triggers a chemical reaction, as a result of which steroid hormones are degraded on the membranes coated with titanium dioxide. Fri, 22 Apr 2022 09:43:15 EDT

Kauai's 2018 record-setting rain caused by a series of supercell thunderstorms
A record-setting rainstorm over Kaua'i, Hawai'i in April 2018 resulted in severe flash flooding and estimated damage of nearly $180 million. The deluge damaged or destroyed 532 homes, and landslides left people along Kaua'i's north coast without access to their homes. Atmospheric scientists have now revealed that severe supercell thunderstorms were to blame. Thu, 21 Apr 2022 18:12:05 EDT
