According to a recent study from Our World In Data, in the early-to-mid 20th century, the average annual death toll from disasters was very high, often climbing to over a million. In recent decades, such deaths are typically fewer than 20,000 people, even as natural disasters become more frequent and more extreme.
The Shark Reef Aquarium on the Las Vegas Strip in Nevada has been sending zebra shark eggs to Indonesia’s Raja Ampat. Researchers hope to release 500 zebra sharks into the wild within 10 years in an effort to support a large, genetically diverse breeding population.
A survey estimated the zebra shark had a population of 20 spread throughout the Raja Ampat archipelago, making the animal functionally extinct in the region.
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.
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.
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.”
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.
Fewer middle-aged people are dying from cancer in the U.K. than at any point over the last 25 years, a new study from Cancer Research UK has revealed. The study showed that overall, mortality rates have dropped by 37% in men and by 33% in women over that span.
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.
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.
Scientists at Yale University adapted existing human cancer treatments to find a new version that could benefit both humans and dogs. After conducting multiple clinical trials involving over 300 dogs over the past eight years, the researchers say that their canine cancer vaccine has almost doubled the 12-month survival rate for dogs with some types of cancer.
