Researchers study healthy ALS neurons as way to understand resistance to the disease

Although largely paralyzed, ALS patients can communicate through eye-tracking devices because they retain eye movement until the disease's late stages. Yet, how some motor neurons resist ALS to allow for this movement has been a mystery.

Researchers create first portable tech for detecting cyanotoxins in water

North Carolina State University researchers have developed the first portable technology that can test for cyanotoxins in water. The device can be used to detect four common types of cyanotoxins, including two for which the U.S. Environmental Protection Agency (EPA) recently finalized recreational water quality criteria.

Microscopic glass blowing used to make tiny optical lenses

Inserting air into hot glass to form a bubble has been used to make glass objects since Roman times. In new work, researchers apply these same glass blowing principles on a microscopic scale to make specialized miniature cone-shaped lenses known as axicons.

Fake news 'vaccine' works: 'Pre-bunking' game reduces susceptibility to disinformation

An online game in which people play the role of propaganda producers to help them identify real world disinformation has been shown to increase "psychological resistance" to fake news, according to a study of 15,000 participants.

Fake drugs that could kill are on the rise in Western countries

Fake medicines—illegal and substandard pharmaceuticals—have until now largely been a problem in low and middle-income countries. Ranging from lifestyle products to lifesaving medicines, such products are now also on the rise in the Western world. The spread is concerning, as fake medicines can be completely ineffective or extremely toxic.

How preschools can do more to support children living with HIV

Thanks to antiretroviral therapy, children living with HIV are likely to live much longer than they would without treatment. They will go to school like other children and develop in much the same way. But how much do their teachers and peers need to know about their HIV-positive status? And what is the best way of managing their particular health needs at preschool level?

Young women who smoke face highest risk of major heart attack

Smoking increases both men's and women's risk of a major heart attack at all ages, but women smokers have a significantly higher increased risk compared to men, especially women under 50 years old, according to a study in the Journal of the American College of Cardiology. Despite the increased risk, smokers can reduce their risk to that of a never smoker in as little as a month after quitting.

Researchers explain visible light from 2-D lead halide perovskites

Researchers drew attention three years ago when they reported that a two-dimensional perovskite—a material with a specific crystal structure—composed of cesium, lead and bromine emitted a strong green light. Crystals that produce light on the green spectrum are desirable because green light, while valuable in itself, can also be relatively easily converted to other forms that emit blue or red light, making it especially important for optical applications ranging from light-emitting devices to sensitive diagnostic tools.

Combatting the world's deadliest infections using groundbreaking human-mimetic tools

A new article published today in the journal Frontiers in Cellular and Infection Microbiology shows that research built around human-mimetic tools are more likely to succeed in the search for effective treatments for and prevention of flavivirus infection as compared to research using monkeys or other animals as laboratory models. The study, led by Dr. David Pamies at the University of Lausanne, with researchers at Johns Hopkins University and the National Institute of Allergy and Infectious Diseases' Vaccines Research Center in the United States, includes a comprehensive review of the models used to study deadly mosquito-borne flaviviruses (MBF) such as dengue fever and the Zika virus, known to cause neurological disease in humans.
