In both cell cultures and mouse models, a drug used to treat Hepatitis C effectively protected and rescued neural cells infected by the Zika virus — and blocked transmission of the virus to mouse fetuses.

MIT researchers have devised a miniaturized system that can deliver tiny quantities of medicine to brain regions as small as 1 cubic millimeter. This type of targeted dosing could make it possible to treat diseases that affect very specific brain circuits, without interfering with the normal function of the rest of the brain, the researchers say.

A type of virus that dominates water samples taken from the world’s oceans has long escaped analysis because it has characteristics that standard tests can’t detect. However, researchers at MIT and the Albert Einstein College of Medicine have now managed to isolate and study representatives of these elusive viruses, which provide a key missing link in virus evolution and play an important role in regulating bacterial populations, as a new study reports.

New research out of York University shows that political dilly-dallying delays global responses to emerging pandemics more than poor surveillance capacity.

Steven J. Hoffman, professor in the Dahdaleh Institute for Global Health Research, Faculty of Health and Osgoode Hall Law School and his colleague Sarah L. Silverberg, conducted an analysis of the three most recent pandemics – H1N1, Ebola and Zika. These were used as case studies to identify and compare sources of delays in responding to pandemics and examine what influences the length of delays.

The idea of having to pay a sin tax for environmentally detrimental foods is gaining more support. For some, eating meat is a sin, and therefore meat products should be taxed like alcohol and tobacco.

A new report published recently by a British group called Farm Animal Investment Risk and Return Initiative (FAIRR) argues that a tax on meat is inevitable.

The vaccines used by commercial fish farmers are not protecting fish from disease, according to a new study.

The study was compiled by researchers at the University of Waterloo, the Pontifical Catholic University of Valparaiso and Chile’s University of Valparaiso. It showed vaccinated fish tend to show more symptoms when contracting diseases, with the health impacts and ultimately deaths occurring as if they’d never received a vaccine.

A strip of chromatography paper similar to that used in rapid pregnancy tests is the basis of a bio-sensor for detecting malaria that has been developed by Brazilian researchers.

For decades, scientists have known that blue light will make fruit flies go blind, but it wasn’t clear why. Now, a Purdue University study has found how this light kills cells in the flies’ eyes, and that could prove a useful model for understanding human ocular diseases such as macular degeneration.

Wildfires, extreme storms and major weather events can seem like a distant threat, but for those whose lives have been directly impacted by these events, the threat hits much closer to home.

Air pollution trapped along the Wasatch Front by winter inversions are estimated to send more than 200 people to the emergency room with pneumonia each year, according to a study by University of Utah Health and Intermountain Healthcare. Bad air quality especially erodes the health of adults over age 65, a population particularly vulnerable to the effects of pneumonia.
