Northwestern University researchers studying the gut bacteria of Scott and Mark Kelly, NASA astronauts and identical twin brothers, as part of a unique human study have found that changes to certain gut “bugs” occur in space.

The Northwestern team is one of 10 NASA-funded research groups studying the Kelly twins to learn how living in space for a long period of time -- such as a mission to Mars -- affects the human body. While Scott spent nearly a year in space, his brother, Mark, remained on Earth, as a ground-based control.

Liquorice and its natural sweetener, glycyrrhizin, can have long-term harmful effects on the development of the fetus.

New research has shown how normally helpful brain cells can turn rogue and kill off other brain cells following injury or disease.Astrocytes have long been implicated in the pathology of a range of human neurodegenerative diseases or injuries including Alzheimer's, Huntington’s Parkinson’s disease, brain trauma and spinal cord injury.

Sophia Antipolis, 3 February 2017: Number of children is emerging as a novel factor that influences the risk for some cardiovascular diseases (CVD), and in some societies in both parents, according to Professor Vera Regitz-Zagrosek, chairperson of the European Society of Cardiology “management of CVD During Pregnancy” guidelines task force.

The “decentralized” water system at the Center for Sustainable Landscapes (CSL) at Phipps Conservatory and Botanical Gardens, which treats all non-potable water on site, contributes to the net-zero building’s recognition as one of the greenest buildings in the world. However, research into the efficacy of these systems versus traditional treatment is practically non-existent in the literature. Thanks to a collaboration between Phipps and the University of Pittsburgh’s Swanson School of Engineering, researchers now have a greater understanding of the life cycle of water reuse systems designed for living buildings, from construction through day-to-day use.

One goal in neurobiology is to understand how the flow of electrical signals through brain circuits gives rise to perception, action, thought, learning and memories.

In a new study, Yale researchers identified a novel genetic defect that prevents brain tumor cells from repairing damaged DNA. They found that the defect is highly sensitive to an existing FDA-approved drug used to treat ovarian cancer — a discovery that challenges current practice for treatment of brain tumors and other cancers with the same genetic defect, said the scientists.

How viruses like Ebola, influenza or even the common cold adapt is a question that affects the health of everyone on earth.  A new Yale University study reveals that gradual exposure to new host species leads to major genetic changes in these pathogens — and possibly makes them more dangerous.

UT Southwestern Medical Center researchers have identified a gene that protects the gut from inflammatory bowel disease (IBD).

A study published in JAMA Cardiology has added to growing evidence that electronic cigarettes (e-cigarettes) are not harmless.
