Plankton blooms in New Zealand suggest the ocean is responding to climate change

The appearance of white blooms of plankton east of New Zealand suggests the ocean is responding to climate change, according to research by Victoria University of Wellington scientists.

As part of her Master's study, Bella Duncan investigated coccolithophores, a white algae with remains known... Read More

Women don’t feel welcome in these STEM fields

Researchers say there are 3 main factors that explain why women are more represented in some STEM (science, technology, engineering, and mathematics) fields than others.

The most powerful one, they say, is a “masculine culture” that makes many women feel like they don’t belong.

“There is w... Read More

Scientists uncover new facets of Zika-related birth defects

In the new study, the scientists observed the virus's effects in animal models at two different points -- during early postnatal development, when the brain is growing rapidly, and at weaning, when the brain has largely reached adult size.

"In early postnatal Zika-infected models some brain a... Read More

New research offers insights into managing agricultural runoff and coastal dead zones

A study published today in Ecology Letters adds to a growing body of work examining the relationship between harmful algal blooms in the Gulf of Mexico and agricultural runoff. The article focuses on water chemistry, specifically the ratio of dissolved silica to dissolved inorganic nitrogen in 1... Read More

Bacteria: Third RNA binding protein identified

Small regulatory RNA molecules are vital for salmonella and other bacteria potentially harmful to humans: This RNA type controls gene activity and allows bacteria to quickly adjust to changing conditions of living and stress as are typical during an infection, for example, when entering the bloo...

Experiment in monkeys raises hopes of "functional cure" for HIV

A new drug combination helped stave off a monkey version of HIV for nearly two years after stopping all treatments, raising hopes for a functional cure for HIV, U.S. researchers said on Thursday.

The treatment involved standard HIV drugs, known as antiretroviral therapy or ART, plus an experi... Read More

Bacteria on Device Said to Infect at Least 12 Patients in Pennsylvania

A device used during open-heart surgery that infected at least 12 patients at a Pennsylvania hospital last year was probably tainted at the plant in Germany where it was made, a federal investigation has found.

The device, called a heater-cooler machine, uses water to regulate the temperature... Read More

A New Zika Zone in Miami, but No Reason to Panic, Scientists Say

Florida announced a new Zika transmission zone on Thursday, saying that the virus had popped up in a mile-square patch of northern Miami and that five people had been infected.

The area, around the Little Haiti neighborhood, goes from NW 79th Street in the north to NW 63rd Street in the south... Read More

Quorum Sensing for the Mutes

It is (almost boringly) obvious that cell-to-cell com­mu­ni­ca­tion is vital in multicellular organisms. To function pro­per­ly, all cells in a tissue have to know – and let their neigh­bors know – where exactly they are, which tasks they're performing right now, when it's time to dif­fer­en­ti­...

Bacteria can make underground nuclear waste repositories safer

Naturally occurring bacteria could consume pent-up hydrogen gas in nuclear waste repositories to prevent radioactive leaks, say researchers at EPFL.

Scientists may have found an unexpected ally in the long-term disposal of nuclear waste: bacteria. In a recent study, a research team led by EPF... Read More

A fungal infection that could help researchers to understand some allergies

Researchers from UPM have revealed how mold from humidity caused by rotting fruits and vegetables unfolds a surprising strategy to infect plants.

A team of researchers from Centre for Plant Biotechnology and Genomics (CBGP, UPM-INIA), has published the results on Alt a1 in an article release... Read More

LudusScope Turns Microbiology Into Real Games (video)

The LudusScope is an interactive smartphone microscope that can be made entirely out of 3D printed or commonly available materials and is easily assembled by middle school or high school students. Developed by Stanford bioengineer Ingmar Riedel-Kruse, it allows students to interact directly with... Read More

Adding a related virus can boost vaccines

The results of a clinical trial suggest it is possible to modify the body’s response to an infection with a related virus.

The researchers report in Nature Microbiology that antibodies, under specific conditions, can intensify infection with a virus related to the causal organism. This phenom... Read More

These are the foods you should eat if you want less smelly farts

Eating slow-release carbs and cutting down on protein may prevent rotten-egg farts according to a study of the gases emitted by human faeces samples.

Farts are mostly composed of odourless gases. There is oxygen and nitrogen from swallowed air, while hydrogen, methane and carbon dioxide are p... Read More

Complete Genome Sequence of Zika Virus Isolated from Semen

A team of researchers from the United Kingdom has obtained the first complete genome sequence of Zika virus that was isolated from a semen sample. The research is published this week in Genome Announcements, a journal of the American Society for Microbiology.

A bacterial role in breast cancer development and prevention

Microbial infection is implicated in an ever-growing number of types of cancer. Adding to the already long list of microbial-associated cancers, an increasing body of evidence suggests breast cancer may also be associated with a specific microbial milieu. A report in Applied and Environmental Mi... Read More

Germs in wastewater often become airborne

Using household wastewater to irrigate food crops in drought-stricken or arid regions isn't the perfect solution. The chemicals and disease-causing germs it might contain could contaminate crops. Viruses that have their origin in the human intestines are often released into the air as fine spray... Read More
