Reston, VA (Embargoed until 11:00 a.m. EDT, Friday, June 11, 2021)--Preclinical trials of a new radiopharmaceutical to treat ovarian cancer have produced successful results, dramatically limiting tumor growth and decreasing tumor mass. Designed specifically for ovarian cancers that are resistant to traditional therapies, the new radiopharmaceutical can be produced in 25 minutes at low cost, which leads to better efficiency compared with alternative methods. This research was presented at the Society of Nuclear Medicine and Molecular Imaging 2021 Annual Meeting. According to the American Cancer Society, more than 20,000 women are diagnosed with ovarian cancer each year and nearly 14,000 ...

The Fenton reaction is a chemical transition involving hydrogen peroxide (H2O2) and the ferrous (iron) ion, which acts as a catalyst. This process is used to destroy hazardous contaminants in wastewater through oxidation. In the atmosphere, a similar reaction, or "Fenton-like" reaction, occurs continuously with ferric oxalate([Fe(III)(C2O4)3]3-) and aerosols suspended in the air. This is the most frequent chemical reaction that occurs in the atmosphere. A particle's ability to oxidize is directly related to its phase, either gaseous or aqueous, which has an important impact on secondary organic aerosol (SOA) formation. Therefore, research is necessary not only to evaluate the contribution of this ...

Researchers at University of California San Diego School of Medicine used an artificial intelligence (AI) algorithm to sift through terabytes of gene expression data -- which genes are "on" or "off" during infection -- to look for shared patterns in patients with past pandemic viral infections, including SARS, MERS and swine flu. Two telltale signatures emerged from the study, published June 11, 2021 in eBiomedicine. One, a set of 166 genes, reveals how the human immune system responds to viral infections. A second set of 20 signature genes predicts the severity of a patient's disease. For example, the need to hospitalize or use ...

Astronomers from University of Warwick and University of Exeter modelling the future of unusual planetary system found a solar system of planets that will 'pinball' off one another Today, the system consists of four massive planets locked in a perfect rhythm Study shows that this perfect rhythm is likely to hold for 3 billion years - but the death of its sun will cause a chain reaction and set the interplanetary pinball game in motion Four planets locked in a perfect rhythm around a nearby star are destined to be pinballed around their solar system when their sun eventually dies, according to a study led by the University of Warwick that peers into its future. Astronomers have modelled how the change in gravitational forces in the system as a result ...

When is a weed not a weed? Can native plants be weeds? Sweet pittosporum (Pittosporum undulatum) was once a well-behaved tree growing in gullies from Gippsland in Victoria up to Brisbane in Queensland. But it is now a major problem, leading to an almost complete suppression of native vegetation where it has invaded. Programs to clear it have successfully allowed indigenous plants to return, and within 15 years, with moderate follow up, treated sites are well on the way to successful restoration. However, there has been some debate on whether this is good or bad for birds such as the threatened Powerful Owl. New research by Monash University scientists from the School of Biological Sciences published today in Ecological Solutions and ...

Astronomers have spotted a giant 'blinking' star towards the centre of the Milky Way, more than 25,000 light years away. An international team of astronomers observed the star, VVV-WIT-08, decreasing in brightness by a factor of 30, so that it nearly disappeared from the sky. While many stars change in brightness because they pulsate or are eclipsed by another star in a binary system, it's exceptionally rare for a star to become fainter over a period of several months and then brighten again. The researchers believe that VVV-WIT-08 may belong to a new class of 'blinking giant' binary star system, where a giant star ? 100 times larger ...

Oncotarget published "The presence of polymorphisms in genes controlling neurotransmitter metabolism and disease prognosis in patients with prostate cancer: a possible link with schizophrenia" reported that polymorphisms of neurotransmitter metabolism genes were studied in patients with prostate cancer (PC) characterized by either reduced or extended serum prostate-specific antigen doubling time corresponding to unfavorable and favorable disease prognosis respectively. The following gene polymorphisms known to be associated with neuropsychiatric disorders were investigated: A. The STin2 VNTR in the serotonin transporter SLC6A4 gene; B. The 30-bp VNTR in the monoamine oxidase A MAOA gene; C. The Val158Met polymorphism in the catechol-ortho-methyltransferase ...

Scientists at Tokyo Institute of Technology (Tokyo Tech) and NEC Corporation jointly develop a 28-GHz phased-array transceiver that supports efficient and reliable 5G communications. The proposed transceiver outperforms previous designs in various regards by adapting fast beam switching and leakage cancellation mechanism. With the recent emergence of innovative technologies, such as the Internet of Things, smart cities, autonomous vehicles, and smart mobility, our world is on the brink of a new age. This stimulates the use of millimeter-wave bands, which have far more signal bandwidth, to accommodate these new ideas. 5G can offer data ...

Medulloblastoma is a rare but devastating childhood brain cancer. This cancer can spread through the spinal fluid and be deposited elsewhere in the brain or spine. Radiation therapy to the whole brain and spine followed by an extra radiation dose to the back of the brain prevents this spread and has been the standard of care. However, the radiation used to treat such tumors takes a toll on the brain, damaging cognitive function, especially in younger patients whose brains are just beginning to develop. A national study led by Washington University School of Medicine in St. Louis and St. Jude Children's Research Hospital suggests that children with what is called "average risk medulloblastoma" can receive a radiation "boost" to a smaller ...

Metformin is a widely prescribed blood sugar-lowering drug. It is often used as an early therapy (in combination with diet and lifestyle changes) for type 2 diabetes, which afflicts more than 34 million Americans. Metformin works by lowering glucose production in the liver, reducing blood sugar levels that, in turn, improve the body's response to insulin. But scientists have also noted that metformin possesses anti-inflammatory properties, though the basis for this activity was not known. In a study published online June 8, 2021 in the journal END ...

Married men who don't help out around the house tend to bring home bigger paychecks than husbands who play a bigger role on the domestic chores front. New research from the University of Notre Dame shows that "disagreeable" men in opposite-sex marriages are less helpful with domestic work, allowing them to devote greater resources to their jobs, which results in higher pay. In contemporary psychology, "agreeableness" is one of the "Big Five" dimensions used to describe human personality. It generally refers to someone who is warm, sympathetic, kind and cooperative. Disagreeable people do not tend to exhibit these characteristics, and they tend to ...

An estimated 8 million tons of plastic trash enters the ocean each year, and most of it is battered by sun and waves into microplastics--tiny flecks that can ride currents hundreds or thousands of miles from their point of entry. The debris can harm sea life and marine ecosystems, and it's extremely difficult to track and clean up. Now, University of Michigan researchers have developed a new way to spot ocean microplastics across the globe and track them over time, providing a day-by-day timeline of where they enter the water, how they move and where they tend to collect. The approach relies on ...

Have you ever been cut off in traffic by another driver, leaving you still seething miles later? Or been interrupted by a colleague in a meeting, and found yourself replaying the event in your head even after you've left work for the day? Minor rude events like this happen frequently, and you may be surprised by the magnitude of the effects they have on our decision-making and functioning. In fact, recent research co-authored by management professor Trevor Foulk at the University of Maryland's Robert H. Smith School of Business suggests that in certain situations, incidental rudeness like this can be deadly. In "Trapped ...

HOUSTON - (June 10, 2021) - Leaders who encourage their employees to learn on the job and speak up with ideas and suggestions for change have teams that are more effective and resilient in the face of unexpected situations, according to new research from Rice University and the University of Windsor. "A Resource Model of Team Resilience Capacity and Learning" will appear in a special issue of Group & Organization Management. Authors Kyle Brykman, an assistant professor at the Odette School of Business at the University of Windsor, and Danielle King, an ...

Music is a tool that has accompanied our evolutionary journey and provided a sense of comfort and social connection for millennia. New research published today in the American Psychologist provides a neuroscientific understanding of the social connection with a new map of the brain when playing music. A team of social neuroscientists from Bar-Ilan University and the University of Chicago introduced a model of the brain that sheds light on the social functions and brain mechanisms that underlie the musical adaptations used for human connection. The model is unique because it focuses on what happens in the brain when people make music together, rather than when they listen to music individually. The research was inspired by creative efforts of people around the world to reproduce ...

Chestnut Hill, Mass. (6/10/2021) - A British man who rejected the standard of care to treat his brain cancer has lived with the typically fatal glioblastoma tumor growing very slowly after adopting a ketogenic diet, providing a case study that researchers say reflects the benefits of using the body's own metabolism to fight this particularly aggressive cancer instead of chemo and radiation therapy. Published recently in the journal Frontiers in Nutrition, the report is the first evaluation of the use of ketogenic metabolic therapy (KMT) without chemo or radiation interventions, on a patient diagnosed with IDH1-mutant glioblastoma (GBM). Ketogenic therapy is a non-toxic nutritional approach, viewed as complementary or ...

Just as the governor announced the start of python hunting season in Florida this month, researchers at the University of Central Florida have published a first- of-its-kind study that shows that near-infrared (NIR) spectrum cameras can help hunters more effectively track down these invasive snakes, especially at night. The snakes, which can reach 26 feet in length and 200 pounds, have invaded the Everglades in Florida -- threatening native species and disrupting the ecosystem. The number of common native species observed in the Everglades since the snakes were first discovered in the 1990s dropped in some species by 90% through 2010, according ...

ITHACA, N.Y. - Researchers from Cornell University's School of Applied and Engineering Physics and Samsung's Advanced Institute of Technology have created a first-of-its-kind metalens - a metamaterial lens - that can be focused using voltage instead of mechanically moving its components. The proof of concept opens the door to a range of compact varifocal lenses for possible use in many imaging applications such as satellites, telescopes and microscopes, which traditionally focus light using curved lenses that adjust using mechanical parts. In some applications, moving traditional glass or plastic lenses ...

Climate change exerts great pressure for change on species and biodiversity. A recent study conducted by the University of Helsinki and the Finnish Environment Institute indicates that the few moth and butterfly species (Lepidoptera) capable of adjusting to a changing climate by advancing their flight period and moving further north have fared the best in Finland. In contrast, roughly 40% of Lepidoptera species have not been able to respond in either way, seeing their populations decline. Climate change is bringing about rapid change in Finnish nature - can species keep up with the pace? Adjusting to climate change can manifest through earlier phenology such as moth and butterfly flight periods, bird nesting, or ...

Researchers remain perplexed as to what causes dementia and how to treat and reverse the cognitive decline seen in patients. In a first-of-its-kind study, researchers at the Medical University of South Carolina (MUSC) and Beth Israel Deaconess Medical Center (BIDMC), Harvard Medical School discovered that cis P-tau, a toxic, non-degradable version of a healthy brain protein, is an early marker of vascular dementia (VaD) and Alzheimer's disease (AD). Their results, published on June 2 in Science Translational Medicine, define the molecular mechanism that causes an accumulation of this toxic protein. Furthermore, they showed that ...

WACO, Texas (June 9, 2021) - Most people listen to music throughout their day and often near bedtime to wind down. But can that actually cause your sleep to suffer? When sleep researcher Michael Scullin, Ph.D., associate professor of psychology and neuroscience at Baylor University, realized he was waking in the middle of the night with a song stuck in his head, he saw an opportunity to study how music -- and particularly stuck songs -- might affect sleep patterns. Scullin's recent study, published in Psychological Science, investigated the relationship between music listening and sleep, focusing on a rarely-explored mechanism: involuntary musical imagery, or "earworms," when a song or tune replays ...

June 10, 2021, CLEVELAND: A new Cleveland Clinic-led study has identified mechanisms by which COVID-19 can lead to Alzheimer's disease-like dementia. The findings, published in Alzheimer's Research & Therapy, indicate an overlap between COVID-19 and brain changes common in Alzheimer's, and may help inform risk management and therapeutic strategies for COVID-19-associated cognitive impairment. Reports of neurological complications in COVID-19 patients and "long-hauler" patients whose symptoms persist after the infection clears are becoming more common, suggesting that SARS-CoV-2 (the virus that causes COVID-19) may have lasting effects on brain function. However, it is not yet well understood how the virus leads to neurological issues. "While some studies suggest ...

The human heart contracts about 70 times per minute, while that of a rat contracts over 300 times; what accounts for this difference? In a new study publishing 10th June in the open-access journal PLOS Biology, led by Michael Geeves and Mark Wass of the University of Kent and Leslie Leinwand from the University of Colorado Boulder, reveal the molecular differences in the heart muscle protein beta myosin that underly the large difference in contraction velocity between the two species. Myosin is a "molecular motor" - an intricate nanomachine that forms the dynamic core of a muscle's contractile machinery, burning ...

Pairing sky-mapping algorithms with advanced immunofluorescence imaging of cancer biopsies, researchers at The Mark Foundation Center for Advanced Genomics and Imaging at Johns Hopkins University and the Bloomberg~Kimmel Institute for Cancer Immunotherapy developed a robust platform to guide immunotherapy by predicting which cancers will respond to specific therapies targeting the immune system. A new platform, called AstroPath, melds astronomic image analysis and mapping with pathology specimens to analyze microscopic images of tumors. Immunofluorescent imaging, using antibodies with fluorescent tags, enables researchers to visualize multiple cellular proteins simultaneously and determine their pattern and strength of expression. Applying AstroPath, ...
