Thousands of people in the U.K. to receive landmark trials for dementia blood tests

By / / Good news links

Thousands of people across the U.K. who are worried about their memory will receive blood tests for dementia in two trials that doctors hope will help to revolutionize the low diagnosis rate. Teams from the University of Oxford and University College London will lead the trials to research the use of cheap and simple tests to detect proteins for people with early stages of dementia or problems with cognition, with the hope of speeding up diagnosis and reaching more people.

Global life expectancy increased by 6.2 years between 1990 and 2021

A new study from the University of Washington’s Institute for Health Metrics and Evaluation found that the super-region of Southeast Asia, East Asia, and Oceania had the world’s largest net gain in life expectancy between 1990 and 2021 (8.3 years), largely due to reductions in mortality from chronic respiratory diseases, stroke, lower respiratory infections, and cancer.

British scientists develop new bifacial solar technology that generates more power at reduced cost

By / / Good news links

Scientists from the University of Surrey in England, working with colleagues at the University of Cambridge, the Chinese Academy of Sciences, Xidian University, and Zhengzhou University, have developed a flexible perovskite solar panel that use electrodes made of tiny carbon nanotubes. The researchers demonstrated that in addition to producing more energy than traditional solar panels, “the material cost of an all-carbon-electrode-based bifacial PSC is about 70% lower than that of a monofacial device.”

Nearly 9 in 10 Americans now think using psilocybin is ‘morally positive,’ in dramatic shift in public opinion

By / / Good news links

Researchers—representing institutions such as the universities of Oxford, Yale, Johns Hopkins, and Grenada—surveyed 795 people on the issue, asking about supervised use specifically for treatment and for well-being enhancement. Participants, the report says, “rated the individual’s decision as morally positive in both contexts.” The study is of note because although psilocybin “has shown promise both as a treatment for psychiatric conditions and as a means of improving well-being in healthy individuals,” authors wrote.

Scientists successfully 3D-print human skin tissue into open wounds

By / / Good news links

Scientists at Pennsylvania State University have successfully 3D-printed living human skin tissue directly into the open wounds of rats for the first time in history. This bioengineering milestone could pave the way for major developments in reconstructive surgery — or even human hair treatments. Current methods of skin and hair reconstruction — like skin grafts — often result in scars, meaning this discovery could lead to a more seamless treatment for humans.

New satellite pinpoints global methane pollution in real-time

By / / Good news links

MethaneSAT, developed by the Environmental Defense Fund in partnership with the New Zealand Space Agency, is the size of a washing machine and cost $88 million to build and launch. While part of its mission is to spot polluters, the other side of the coin is that it can verify that others are indeed managing those emissions in a responsible fashion. Stemming methane leaks is the fastest single way to curb the escalation of average global temperatures, according to The Guardian.

79% of Crohn’s disease patients in remission after early intervention

By / / Good news links

Led by researchers from the University of Cambridge, a clinical trial examined the effectiveness of giving the immunotherapy drug infliximab earlier, as soon as possible after diagnosis. They employed what’s called a ‘top-down’ strategy, meaning the drug was given straight after diagnosis regardless of the patient’s symptom severity. They found that this early intervention significantly reduces complications of this often debilitating disease, including the need for surgery by a factor of 10.
