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

HIV, malaria, and tuberculosis: Success of the Millennium shown in most comprehensive study to date

Accelerated progress against the global burden of HIV, malaria, and tuberculosis (TB) has been made since 2000 when governments worldwide adopted Millennium Development Goal 6 to combat HIV/AIDS, malaria, and TB. New estimates from a major new analysis show that worldwide, the number of people l... 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

Viral relics show cancer's 'footprint' on our evolution

Cancer has left its 'footprint' on our evolution, according to a study which examined how the relics of ancient viruses are preserved in the genomes of 38 mammal species.

Viral relics are evidence of the ancient battles our genes have fought against infection. Occasionally the retroviruses th... Read More

Terms of Biology: The Pan-Genome

A still somewhat unfamiliar term is floating around: the pan-genome. In 2005, Tettelin et al. coined the term along with genome analyses of eight Streptococcus agalactiae strains, and Merry introduced it to this blog, some time back already. Today, a keyword search in PubMed returns roughly 200 ... 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...

How zinc starves lethal bacteria to stop infection

Australian researchers have found that zinc can 'starve' one of the world's most deadly bacteria by preventing its uptake of an essential metal.

The finding, by infectious disease researchers at the University of Adelaide and The University of Queensland, opens the way for further work to des... Read More

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

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...

How a microscopic team alters the course of carbon in the Atlantic ocean - Finalist in Ocean 180 Video Challenge

The Amazon river is the largest river in the world. It drains the entire Amazon rainforest, sending leftover nutrients, detritus, and minerals from the South American jungle out into the tropical Atlantic ocean. This runoff forms a freshwater plume, hundreds of miles across, that profoundly affe... 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

ICAAC 2013 - Human Interferon Kills Resistant H7N9 Influenza


During the April 2013 avian influenza A (H7N9) outbreak, more than 130 human infections with H7N9 were reported. Most patients had ... Read More

Animating the Inanimate

Concrete is the most widely used building material in the world, with untold amounts being produced yearly. It has always been regarded as a strong, solid, impenetrable, almost indestructible material yet it can make cracks that are vulnerable to penetration by water. As the result, structures ...

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

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.

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

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

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
