Single dose of century-old drug approved for sleeping sickness reverses autism-like symptoms in mice

In a further test of a novel theory that suggests autism is the consequence of abnormal cell communication, researchers report that an almost century-old drug approved for treating sleeping sickness also restores normal cellular signaling in a mouse model of autism, reversing symptoms of the neu...

Tiny plastic dwellers have big impact on our oceans

Microscopic creatures that live on tiny ocean plastics greatly affect the fate and ecological impacts of marine plastic pollution, according to researchers from The University of Western Australia.

PhD candidate Julia Reisser and colleagues have published an article in the international journ... Read More

Scientists Turn Dr. Frankenstein, Re-Write Bacteria’s Entire Genome

It may sound like science fiction, but researchers at Yale and Harvard have taken the first steps towards a Dr. Frankenstein-type reality, by fundamentally changing the genetic code of an organism.

The scientists were able to rewrite the genetic alphabet of the common bacteria E.coli, creatin... Read More

Oregon geologist says Curiosity's images show Earth-like soils on Mars

Soil deep in a crater dating to some 3.7 billion years ago contains evidence that Mars was once much warmer and wetter, says University of Oregon geologist Gregory Retallack, based on images and data captured by the rover Curiosity.

NASA rovers have shown Martian landscapes littered with loos... Read More

Ocean microbes display a hidden talent: releasing countless tiny lipid-filled sacs

In the search for a renewable energy source, systems using algae look like a good bet. Algae can grow quickly and in high concentrations in areas unsuitable for agriculture; and as they grow, they accumulate large quantities of lipids, carbon-containing molecules that can be extracted and conver...

Beer Science: Crafting the Perfect Pint

Oregon has 171 breweries operating out of 70 different cities, and Portland boasts more breweries per capita than any other city in the country. Two Oregon brew experts—Leon Fyfe, a microbiologist with the Craft Brew Alliance, and Ben Tilley, owner of Agrarian Ales—pour over the science of craft... Read More

Evolution depends on rare chance events, 'molecular time travel' experiments show

Chance events may profoundly shape history. What if Franz Ferdinand's driver had not taken a wrong turn, bringing the Duke face to face with his assassin? Would World War I still have been fought? Would Hitler have risen to power decades later?

Historians can only speculate on what might have... Read More

ASM GM 2014 - The Potential Role of Gut Microbes in Autism

Most gut bacteria are beneficial, aiding food digestion, producing vitamins, and protecting against harmful bacteria. If left unchecked, however, harmful bacteria can excrete... Read More

Researchers create three-dimensional model of bacterium

Certain bacteria can build such complex membrane structures that, in terms of complexity and dynamics, look like eukaryotes, i.e., organisms with a distinct membrane-bound nucleus. Scientists from Heidelberg University and the European Molecular Biology Laboratory (EMBL) made this discovery empl... Read More

Caribbean health experts warn of a rapidly spreading mosquito-borne virus

Caribbean health experts warned last week that they “cannot stop” a rapidly spreading mosquito-borne virus that has infected thousands and is associated with six deaths in the region.

The alert came as the Dominican Republic’s health ministry became the 15th Caribbean nation to confirm cases ... Read More

Retrospective, June 2014 - Small Things Considered

As is our custom at this time of year, we go over the material that has appeared in this blog over the last six months. Seems like a lot of stuff, but it’s the result of the work of quite a number of dedicated people, all of whom deserve our gratitude.

Oman says first MERS-coronavirus sufferer dies in hospital

Oman's first MERS coronavirus patient died in hospital on Sunday from lung failure, state news agency ONA said.

The Middle East Respiratory Syndrome Coronavirus (MERS-CoV), which can cause coughing, fever and pneumonia, emerged in Saudi Arabia last year and has been reported in Qatar, France,... Read More

Much breast milk bought online is contaminated, analysis shows

Desperate for breast milk, some new mothers who can't nurse their babies are turning to online sources, typically strangers with ample supplies. But a new study finds that human milk bought and sold on the Internet may be contaminated — and dangerous.

Nearly 75 percent of breast milk bought t... Read More

Malaria control: The great mosquito hunt

The armed guards at Mali's Bamako Senou International Airport had never seen a German shepherd before. The only dogs they were familiar with were the small, scrappy mixed breeds that are common in West Africa. So when Dana, a wolf-like purebred from California, stepped off a plane and into the a...

Methane-Munching Microorganisms Meddle with Metals

On the continental margins, where the seafloor drops hundreds of meters below the water’s surface, low temperatures and high pressure lock methane inside ice crystals. Called methane hydrates, these crystals are a potential energy source, but they are also a potential source of global warming if... Read More

Laser tool speeds up detection of Salmonella in food products

Purdue University researchers have developed a laser sensor that can identify Salmonella bacteria grown from food samples about three times faster than conventional detection methods.

Known as BARDOT (pronounced bar-DOH'), the machine scans bacteria colonies and generates a distinct black and... Read More

Biotransformation of Enniatins from Fusarium Fungi in a Food Safety Perspective

Mould species of the genera Fusarium and Altenaria are considered the most important threats to Norwegian grain cereals because they produce toxins which can be a potential risk to food safety. F. avenaceum, the fungi most frequently isolated from Norwegian grain, produces enniatins which have b... Read More

UC Davis Researchers Find How Viral Infection Disrupts Neural Development in Offspring, Increasing Risk of Autism

Activating a mother’s immune system during her pregnancy disrupts the development of neural cells in the brain of her offspring and damages the cells' ability to transmit signals and communicate with one another, researchers with the UC Davis Center for Neuroscience and Department of Neurology h...

TB infection in lungs decreases diversity of gut bacteria

Johns Hopkins researchers have found evidence in mice that a tuberculosis (TB) infection in the lungs triggers immune system signaling to the gut that temporarily decreases the diversity of bacteria in that part of the digestive tract.

The Johns Hopkins researchers showed that this decrease i... Read More

World changing technology enables crops to take nitrogen from the air

A major new technology has been developed by The University of Nottingham, which enables all of the world’s crops to take nitrogen from the air rather than expensive and environmentally damaging fertilisers.

Nitrogen fixation, the process by which nitrogen is converted to ammonia, is vital fo... Read More
