Detailed map of human tongue microbiome

Wed, 03/25/2020 - 07:44
A new study published in the journal Cell Reports in March 2020 reports the use of advanced and rapid spectral imaging techniques to develop a detailed map of microbial communities on the human tongue. The research will help to understand how such communities grow and form organized patterns.

German scientists test TB vaccine against coronavirus

Wed, 03/25/2020 - 05:17
The coronavirus disease (COVID-19) had taken a toll on the world, affecting 168 countries and more than 417,000 people. So far, more than 18,600 people have died due to complications of the disease. Scientists across the globe race to develop the first vaccine against the novel coronavirus.

Step count matters - lowers risk of death

Wed, 03/25/2020 - 04:16
A new study shows that wearing a device that measures the number of steps taken over the course of the day reduces the overall death rate in US adults. The study was published in the journal JAMA in March 2020.

Quality of diet among young Americans remains poor

Wed, 03/25/2020 - 04:03
Poor diet is a significant contributor to chronic diseases, including cardiovascular disease, cancer, obesity, and diabetes accounting for early mortality. A new study published in the journal JAMA in March 2020 shows that dietary deficiency is both prevalent and pathogenic in today’s young America.

Researchers propose a stopgap measure to help Covid-19 patients in respiratory distress

Wed, 03/25/2020 - 00:58
Researchers at MIT and the University of Colorado at Denver have proposed a stopgap measure that they believe could help Covid-19 patients who are in acute respiratory distress.

Vaporized cannabis increases drug-seeking behavior, study shows

Wed, 03/25/2020 - 00:39
Rats with regular access to cannabis seek more of the substance and tend to show increased drug-seeking behavior when cannabis is absent.

Research team identifies a molecule that directs neurons

Tue, 03/24/2020 - 23:42
The habenula is a small region at the centre of the brain, but is crucial for people's lives. It is made up of groups of nerve cells that control the "neurotransmitters" of the brain, that is to say substances like dopamine, noradrenaline and serotonin.

Nearly all older Americans support adding a dental benefit to the Medicare program that covers most people over age 65, according to a new national poll that also reveals how often costs get in the way of oral health for older adults.

Cannabidiol helps fight antibiotic-resistant bacteria

Tue, 03/24/2020 - 23:04
Since the discovery of penicillin in 1928 by Sir Alexander Fleming, antibiotics have saved millions of lives from fatal infections world-wide. However, with time bacteria have developed mechanisms to escape the effects of antibiotics - they have become resistant.

Commonly used mouthwash increases lactate-producing bacteria that lower saliva pH

Tue, 03/24/2020 - 22:35
The first study looking at the effect of chlorhexidine mouthwash on the entire oral microbiome has found its use significantly increases the abundance of lactate-producing bacteria that lower saliva pH, and may increase the risk of tooth damage.

Penn State engineers model genetic mutations causing drug resistance

Tue, 03/24/2020 - 22:31
Whether it is a drug-resistant strain of bacteria, or cancer cells that no longer react to the drugs intended to kill them, diverse mutations make cells resistant to chemicals, and "second generation" approaches are needed.

Bedtime deviations may affect cardiovascular health

Tue, 03/24/2020 - 22:23
Despite increasing awareness of how critical sleep is to our health, getting a good night's rest remains increasingly difficult in a world that's always "on" -; responding to emails at all hours, news cycles that change with every tweet and staring endlessly into the blue light of cell phone, tablet and computers screens.
