Menadione, a vitamin K precursor, shows promise in slowing prostate cancer in mice by disrupting cancer cell survival processes, with potential applications for human treatment and myotubular myopathy therapy. Prostate cancer is a quiet killer. In most men, it’s treatable. While it’s treatable in many men, some cases prove resistant to all current therapies [...]

Within a cell, DNA carries the genetic code for building proteins. To build proteins, the cell makes a copy of DNA, called mRNA. Then, another molecule called a ribosome reads the mRNA, translating it into protein. But this step has been a visual mystery; scientists previously did not know how the ribosome attaches to [...]

Smoking and vaping impair vascular function, even without nicotine, with the most significant effects seen in nicotine-containing e-cigarettes. Researchers recommend avoiding both for better health. Researchers have discovered immediate impacts of cigarette and e-cigarette smoking on vascular function, even in the absence of nicotine. Findings from the ongoing study were recently presented at the [...]

Twice-yearly injections of the capsid inhibitor drug lenacapavir can prevent the vast majority of HIV infections, according to a Phase 3 clinical trial published Wednesday in the New England Journal of Medicine. HIV pre-exposure prophylaxis (PrEP) has emerged as a crucial tool for fighting the global HIV epidemic, but researchers say daily pill regimens [...]

Researchers have uncovered how certain genetic mutations lead to unique spherical amyloid plaques in inherited forms of Alzheimer’s, offering insights that could advance our understanding of the disease and improve therapeutic strategies. An international collaboration led by RIKEN researchers has discovered how unusual spherical structures form in the brains of people with a mutation that [...]

New research by Northwestern Medicine reveals how humans have evolved advanced brain regions to interpret others’ thoughts, connecting these areas with the amygdala, a part of the brain involved in emotional processing. Study sought to better understand how humans evolved to become skilled at thinking about others. Newer parts of the brain that support [...]

New research offers a potential explanation for the formation of early Earth protocells. Few questions have captivated humankind more than the mystery of life’s origins on Earth. How did the first living cells emerge? How did these early protocells develop the structural membranes essential for thriving and eventually assembling into complex organisms? New research [...]

An international research team, led by the University of Wollongong (UOW), has found wearable organic X-ray sensors could offer safer radiotherapy protocols for cancer patients. More than 400 people are diagnosed with cancer every day in Australia and 50% of these people will go on to be treated with radiotherapy. The side-effects of cancer [...]

MIT researchers have introduced an efficient reinforcement learning algorithm that enhances AI’s decision-making in complex scenarios, such as city traffic control. By strategically selecting optimal tasks for training, the algorithm achieves significantly improved performance with far less data, offering a 50x boost in efficiency. This method not only saves time and resources but also paves [...]
