Mercury has magnetic storms

An international team of scientists has proved that Mercury, our solar system's smallest planet, has geomagnetic storms similar to those on Earth. Their finding, a first, answers the question of whether other planets, including those outside our solar system, can have geomagnetic storms regardless of the size of their magnetosphere or whether they have an Earth-like ionosphere. source https://www.sciencedaily.com/releases/2022/03/220331101604.htm

How e-scooters can safely operate in a city

E-scooters have become a familiar sight in cities worldwide in recent years, with many new companies renting them for use. But their arrival has also brought new safety concerns. Now, researchers present a framework for comparing how different micromobility vehicles, such as e-scooters, and bicycles move in cities, a methodology that can benefit companies and local authorities alike, and -- most importantly -- contribute to improving traffic safety. source https://www.sciencedaily.com/releases/2022/03/220331101554.htm

Most face masks don't expose wearers to harmful levels of PFAS, study says

Face masks are important for slowing the spread of COVID-19 and protecting against smoke. Per- and polyfluoroalkyl substances (PFAS) are added to many products to repel fluids, but their presence in face masks hasn't been thoroughly studied. Now, researchers have found that most face masks tested contain low or negligible levels of PFAS, except for one marketed to firefighters, which could pose health risks in certain situations. source https://www.sciencedaily.com/releases/2022/03/220330103215.htm

Common coronavirus infections don't generate effective antibodies against SARS-CoV-2, study finds

Researchers have shown that infections with two different common human coronaviruses (HCoVs) don't generate antibodies that effectively cross-react with SARS-CoV-2. So, prior infection with HCoVs is unlikely to protect against COVID-19 or worsen a SARS-CoV-2 infection through antibody-dependent enhancement (ADE), the researchers say. source https://www.sciencedaily.com/releases/2022/03/220330103212.htm

Plastic bag bans may unintentionally drive other bag sales

When cities or counties institute plastic bag bans or fees, the idea is to reduce the amount of plastic headed to the landfill.

Unprecedented videos show RNA switching ‘on’ and ‘off’

Using new simulations, researchers discovered one part of RNA smoothly invades and displaces another part of the same RNA, enabling the structure to rapidly and dramatically change shape. Called strand displacement, this mechanism appears to switch genetic expression from 'on' to 'off'. source https://www.sciencedaily.com/releases/2022/03/220328133656.htm
