Fampridine is currently used to improve walking ability in multiple sclerosis. A new study shows that it could also help individuals with reduced working memory, as seen in mental health conditions like schizophrenia or depression.

Alcohol-related deaths in the U.S. nearly doubled from 1999 to 2020. The sharpest spike occurred among 25- to 34-year-olds (nearly fourfold), while individuals aged 55 to 64 had the highest rates. Men consistently had higher rates but women saw the largest proportional rise, with deaths increasing 2.5 times. Asian and Pacific Islander communities experienced the steepest ethnic increase, while the Midwest saw the greatest regional rise (2.5 times), followed by the Northeast, West, and South.

The history of a major animal group, composed of millions of species of insects, arachnids, and nemotodes, has been elusive — until now. A team has now identified the oldest known ecdysozoan in the fossil record and the only one from the Precambrian period.

Researchers have discovered a mechanism behind the yo-yo effect: fat cells have a memory that is based on epigenetics.

An international group of authors who developed the science behind net zero demonstrate that relying on ‘natural carbon sinks’ like forests and oceans to offset ongoing CO2 emissions from fossil fuel use will not actually stop global warming. The science of net zero, developed over 15 years ago, does not include these natural carbon sinks in the definition of net human-induced CO2 emissions. Yet governments and corporations are increasingly turning to them to offset emissions, rather than reducing fossil fuel use or developing more permanent CO2 disposal options. Emissions accounting rules encourage this by creating an apparent equivalence between fossil fuel emissions and drawdown of CO2 by some natural carbon sinks, meaning a country could appear to have ‘achieved net zero’ whilst still contributing to ongoing warming.

Clinical visits by patients suffering ocular surface eye conditions more than doubled during times when ambient particulate matter from air pollution was in the atmosphere, signaling a possible association between climate change and ocular health, according to a new study.

Fish stocks along the West African coast have declined significantly over the past five decades, threatening food security and the livelihoods of the fishing communities that depend on them, according to a new study.

Quantum-science advances using AI can measure very small surfaces and distances — opening a world of medical, manufacturing and other applications.

Employees struggle when supervisors swing between good and bad behavior

Some of the first human beings to arrive in Tasmania, over 41,000 years ago, used fire to shape and manage the landscape, about 2,000 years earlier than previously thought.
