“The changing nature of sea ice, with earlier and erratic periods of thaw, could be altering the processing and release of pollutants alongside key nutrients, which in turn affects biota at the base of the marine food web,” says environmental chemist Crispin Halsall, from Lancaster University in the UK.

Polyfluoroalkyl and perfluoroalkyl substances (PFAS) are known as ‘forever chemicals’ because they don’t naturally break down in the environment. Now a new study reveals the increasing pace of Arctic ice melt is leaking more of these chemicals into the environment.

PFAS don’t originate in the Arctic, but they do settle there – they’re used in all kinds of human-made products and processes, from pizza boxes to foam used to fight fires. Once released into the atmosphere, they’re often trapped in Arctic ice floes.

This study builds on an earlier paper by the Rothstein lab that looked at the most common genetic cause of ALS, a mutation in the C9orf72 gene (also referred to as the “C9 mutation”). There, they showed that the C9 mutation produced defects in a structure called the nuclear pore that is responsible for moving proteins and other molecules in and out of the nucleus of cells.

Amyotrophic lateral sclerosis (ALS) is a rapidly progressive and fatal degenerative disease affecting the nerve cells in the brain and spinal cord responsible for controlling voluntary muscle movement. “Sporadic” or non-inherited ALS, accounts for roughly 90% percent of cases, and 10% of cases are due to known genetic mutations. By studying lab-grown neurons derived from skin or blood cells from 10 normal controls, eight with an ALS causing mutation, and 17 with non-inherited ALS, researchers have found a possible starting point for the dysfunction that causes the disease. The study, which was published in Science Translational Medicine, was funded in part by the National Institute for Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health.

Using a library of ALS patient-derived cells, the research team led by Jeffrey Rothstein, M.D., Ph.D., at Johns Hopkins University School of Medicine, Baltimore, developed induced pluripotent stem cell (iPSC)-derived neurons from the patients’ cultured cells to discover a common defect regardless of whether the cell came from persons with inherited or non-inherited ALS. They report that in ALS nerve cells, there is an accumulation of a protein called CHMP7 in the nucleus of cultured nerve cells as well as in ALS samples from the brain region that controls movement. Treatments that decrease the amount of CHMP7 in the cultured cells prevented a series of abnormalities that are characteristic of ALS.

Following the approval of the consent law by Danish parliament in December 2020, a team of Danish developers released iConsent, which allows users to send a request for consent via their phone to a potential partner, who can then accept or reject the encounter. Via @WIREDUK

Denmark’s iConsent aims to support new sexual consent legislation – but does it lack the sex appeal for everyday use?

Big shift in the making.

Like other militaries, the Israel Defense Forces for years looked like one organization from the outside, but its services were balkanized in using different networks and data services, an IDF digital leader said in an interview.

A company that makes an implantable brain-computer interface (BCI) has been given the go-ahead by the Food and Drug Administration to run a clinical trial with human patients. Synchron plans to start an early feasibility study of its Stentrode implant later this year at Mount Sinai Hospital, New York with six subjects. The company said it will assess the device’s “safety and efficacy in patients with severe paralysis.” https://www.engadget.com/fda-brain-computer-interface-clinic…ml?src=rss

A company that makes an implantable has been given the go-ahead by the Food and Drug Administration to run a clinical trial with human patients. Synchron plans to start an early feasibility study of its Stentrode implant later this year at Mount Sinai Hospital, New York with six subjects. The company said it will assess the device’s “safety and efficacy in patients with severe paralysis.”

Synchron received the FDA’s green light ahead of competitors like Elon Musk’s. Before such companies can sell BCIs commercially in the US, they need to prove that the devices work and are safe. The FDA will provide guidance for trials of BCI devices for patients with paralysis or amputation during a webinar on Thursday.

Reviewing the images of Ganymede’s aurora, the team discovered that, as the moon’s surface temperature rises and falls throughout the day, it becomes warm enough around noon near the equator for sublimation to occur, releasing water molecules.

“In a wider sense, this discovery shows that often one needs to know what to focus on when analyzing data. The signal from H₂O was present in the HST images since 1998,” said lead author Lorenz Roth. “Only with additional information through new data and predictions from theoretical studies, we knew what to look for and where to search for it. There are likely many more things to discover in the gigantic dataset that the Hubble Space Telescope has accumulated over its three decades in space.”
