The biosynthesis of the great variety of natural plant products has not yet been elucidated for many medically interesting substances. In a new study, an international team of researchers was able to show how ipecacuanha alkaloids, substances used in traditional medicine, are synthesized. They compared two distantly related plant species and were able to show that although both plant species use a comparable chemical approach, the enzymes they need for... Read more ›

Researchers have identified a gene that plays a key role in prostate cancer cells that have transitioned to a more aggressive, treatment-resistant form. The gene can be indirectly targeted with an existing class of drugs, suggesting a potential treatment strategy for patients with aggressive subtypes of prostate cancer. Read more ›

Chronic inflammatory bowel disease is challenging to treat and carries a risk of complications, including the development of bowel cancer. Young people are particularly affected: when genetic predisposition and certain factors coincide, diseases such as ulcerative colitis or Crohn's disease usually manifest between the ages of 15 and 29 -- a critical period for education and early career development. Prompt diagnosis and treatment are crucial. Researchers have now discovered a... Read more ›

New research adds to our understanding of how rapidly rising sea levels due to climate change foreshadow the end of the Great Barrier Reef as we know it. The findings suggest the reef can withstand rising sea levels in isolation but is vulnerable to associated environmental stressors arising from global climate change. Read more ›

Aortic valve narrowing (aortic stenosis) with concomitant cardiac amyloidosis is a severe heart disease of old age that is associated with a high risk of death. Until now, treatment has consisted of valve replacement, while the deposits in the heart muscle, known as amyloidosis, often remain untreated. Researchers have now demonstrated that combined treatment consisting of heart valve replacement and specific drug therapy offers a significant survival advantage for patients. Read more ›

Global warming is continuously advancing. How quickly this will happen can now be predicted more accurately than ever before, thanks to a method developed by climate researchers. Anthropogenic global warming is set to exceed 1.5 degrees Celsius by 2028 and hence improved quantification of the Paris goals is proposed. Read more ›

Despite advances in machine vision, processing visual data requires substantial computing resources and energy, limiting deployment in edge devices. Now, researchers from Japan have developed a self-powered artificial synapse that distinguishes colors with high resolution across the visible spectrum, approaching human eye capabilities. The device, which integrates dye-sensitized solar cells, generates its electricity and can perform complex logic operations without additional circuitry, paving the way for c Read more ›

Human-AI interactions are well understood in terms of trust and companionship. However, the role of attachment and experiences in such relationships is not entirely clear. In a new breakthrough, researchers from Waseda University have devised a novel self-report scale and highlighted the concepts of attachment anxiety and avoidance toward AI. Their work is expected to serve as a guideline to further explore human-AI relationships and incorporate ethical considerations in AI... Read more ›

Some microbes living on sand grains use up all the oxygen around them. Their neighbors, left without oxygen, make the best of it: They use nitrate in the surrounding water for denitrification -- a process hardly possible when oxygen is present. This denitrification in sandy sediments in well-oxygenated waters can substantially contribute to nitrogen loss in the oceans. Read more ›

Tracing the origin of an ultra-hot exoplanet: The chemical composition of WASP-121b suggests that it formed in a cool zone of its natal disc, comparable to the region of gas and ice giants in our Solar System. Methane indicates unexpected atmospheric dynamics: Despite extreme heat, methane was detected on the nightside -- a finding that can be explained by strong vertical atmospheric circulation. First detection of silicon monoxide in a... Read more ›
