So-called "good fatty acids" are essential for human health and much sought after by those who try to eat healthily. Among the Omega-3 fatty acids, DHA or docosahexaenoic acid is crucial to brain function, vision and the regulation of inflammatory phenomena. In addition to these virtues, DHA is also associated with a reduction in the incidence of cancer. How it works is the subject of a major discovery by a multidisciplinary team of University of Louvain (UCLouvain) researchers, who have just elucidated the biochemical mechanism that allows DHA and other related fatty acids to slow the development of tumours. This is a major advance that has recently been published ...

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 ...
