Marine bacteria genes can help track environmental changes caused by humans

The gene expression of marine bacteria can be a valuable sensor for discovering environmental changes caused by humans. Furthermore, bacteria help to clean our oceans and hopefully they could be used to purify drinking water from harmful environmental toxins in the future.

Study provides evidence of aerosol exposure to microcystins among coastal residents

Florida has experienced numerous harmful algal blooms in recent years, including blue-green algae and their toxins in 2016 and 2018. Despite their intensity and frequency, there is scant data on human exposure to these blooms and concentrations of the toxins they produce in tissues of exposed individuals.

KAIST researchers identify mechanism that fuels a 'domino effect' in cancer drug resistance

KAIST researchers have identified mechanisms that relay prior acquired resistance to the first-line chemotherapy to the second-line targeted therapy, fueling a "domino effect" in cancer drug resistance.

Burrowing mayfly’s decline offers an early warning system for changes in our ecosystems

Mayflies have long been indicators of the ecological health of the lakes, rivers, and streams. The more mayflies present in water, the better the water quality.

Princeton's Bonnie Bassler awarded the 2020 Gruber Genetics Prize

The 2020 Gruber Genetics Prize is being awarded to geneticist Bonnie Bassler, Ph.D. of Princeton University and the Howard Hughes Medical Institute, for her groundbreaking work on how bacteria "talk" to each other using molecular "languages."

Fly model could help lay the foundation for new therapies to fight 'difficult' pathogen

The Clostridium difficile pathogen takes its name from the French word for "difficult." A bacterium that is known to cause symptoms ranging from diarrhea to life-threatening colon damage, C. difficile is part of a growing epidemic of concern for the elderly and patients on antibiotics.

Natural antioxidant reverses reproductive harms caused by BPA exposure in worms

From plastics to pesticides, it seems like every week delivers fresh news about the dangers of endocrine disruptors--chemicals in the environment that alter the body's hormones and can lead to reproductive, developmental, neurologic and immune problems and cancer.

Gut microbes in wasps help overcome pesticides

An intriguing study published in February 2020 in the journal Cell Host & Microbe reports that when wasps are exposed to atrazine, a commonly used pesticide, the gut microbiome undergoes changes that help them overcome the ill-effects of the exposure. In addition, the changes are passed on to the offspring, which means that the next generation will also inherit atrazine resistance even without being exposed to the chemical.

Cigarettes kill even after you put them out

There are more than 5 trillion (that’s 5 thousand billion, or 5 million million or, 5,000,000,000,000) cigarette butts littering the world. These cause dust and dirt to pile up, clutter public places, and may have an adverse influence on ground water and wildlife. But little thought has gone into whether they also pollute the air.

Curbing e-cigarettes: do government regulations work?

A new study published in January 2020 in the journal JAMA Network Open shows that government regulations restricting the use of e-cigarettes may be instrumental in reducing the use of these devices by American adults.

High-fiber diet can reverse adverse effects of environmental toxins on cardiovascular health

Research from the University of Kentucky's Superfund Research Center (UK-SRC) shows that a diet high in fiber could possibly reverse the adverse effects that environmental toxins have on cardiovascular health.

Even extinguished cigarettes release toxins, shows study

Cigarette butts pile up in parks, beaches, streets and bus stops, places where all types of littering are frowned upon.

UB team receives $2 million NIH grant for enzyme research

In the human body, proteins called enzymes help speed up chemical reactions that are vital for life.

Bandages sense infections, change color, treat infection

In what reads like science fiction, a new study published in the journal ACS Central Science reports the development of bandages that detect the presence of bacteria in wounds and change color, depending on whether they are drug-sensitive or drug-resistant. This is an important step in helping patients recover better.

Finer particulate matter (PM1) and risk of cardiovascular disease

A new study published in the journal Environmental Science & Technology Letters reports that particulate matter smaller than a single micron in diameter, called PM1, is strongly linked to the occurrence of cardiovascular disease (CVD). This is thought to be due to its higher surface area to volume ratio.

New research project aims to slow down the progression of heart failure

A new research project funded by the British Heart Foundation at the University of Manchester aims to find a way to slow down the progression of heart failure.

Researchers discover a defense mechanism that protects cells from microbial attacks

Human cells have a defense mechanism that protects them from microbial attacks, a Canadian-led team of international researchers has discovered.

Research unravels consequences of Zika virus attack on neural cells

Previous studies regarding the damage of the Zika virus on the brain had already pointed out the virus's predilection for a certain neural cell: the astrocyte. However, few studies have proposed to identify the infection effects on these cells, as well as their association with developmental alterations, including brain malformations and microcephaly.

Snake stem cells create real venom to use as medicine

Poisonous snakes kill more than 90,000 people each year across the globe, with about 1.2 million to 5.5 million snake bites occur annually. Despite the venomous bite, scientists have limited knowledge of the snake’s venom, complicating efforts to develop treatments. A new study has found that snake venom gland cells can be cultured in the lab as adult-stem-cell-based organoids, producing real venom, which can be used to develop treatments.

Researchers win 2019 AAAS Newcomb Cleveland Prize for malaria-fighting technology

A team of nine researchers based in the United States and Burkina Faso will receive the 2019 Newcomb Cleveland Prize, presented by the American Association for the Advancement of Science, for the development of a promising tool in the global fight against malaria and other diseases transmitted by mosquitoes, including dengue and Zika.
