A nanoparticle wrapped in material taken from the membranes of red blood cells could become the basis for vaccines against a range of infectious bacteria, including MRSA (methicillin-resistant Staphylococcus aureus), an infection that kills tens of thousands of people every year.

DNA carries out its activities "diluted" in the cell nucleus. In this state it synthesises proteins and, even though it looks like a messy tangle of thread, in actual fact its structure is governed by precise rules that are important for it to carry out its functions. Biologists have studied DNA... Read More
The lack of data on the effectiveness of medicines available to doctors and researchers is "of extreme concern" say a group of MPs.
The Public Accounts Committee is calling for all data on drugs being prescribed in the UK to be made available.
It also says the government spent £424m stockp... Read More
Membrane proteins are the “gatekeepers” that allow information and molecules to pass into and out of a cell. Until recently, the microscopic study of these complex proteins has been restricted due to limitations of “force microscopes” that are available to researchers and the one-dimensional res...

Slime molds may not have brains, but that isn't preventing some computer scientists from investigating them for their potential as novel, unconventional computers. A slime mold consists of a single cell containing millions of nuclei, and forms a network of protoplasmic tubes to move toward its f... Read More
A key theory of the cell cycle of asymmetric bacteria, which has prevailed for the last ten years, has been disproved by a combined approach using mathematical modelling and genetic experiments.
Modellers Prof. Martin Howard and Dr Seán Murray, from the John Innes Centre on the Norwich Resear... Read More
Although a population of bacteria may be genetically identical, individual bacteria within that population can act in radically different ways.
As these bacterial cells divide, chemotaxis machinery (bright blue and red) localize in one daughter cell
This phenomenon is crucial in the bacter... Read More
Rare is the holiday meal that does not owe many of its pleasures to invisible cooks with tongue-twisting names. Do you enjoy charcuterie and pickles? Bread with cultured butter? A drizzle of vinaigrette on this or that? A bit of cheese? Some chocolates? Wine, beer or cider? Then raise a glass to... Read More
Hi everybody, I saw this in a plash near my house and there was a lot of them. Can somebody help me about the identification or send a link if you know some kind of protozoa base Read More
University of Iowa researchers have developed a new vaccine that protects against lethal pneumonia caused by Staphylococcus aureus (staph) bacteria, including drug-resistant strains like MRSA.
The research team was led by Patrick Schlievert, professor and chair of microbiology in the UI Carve... Read More
An unprecedented wintertime outbreak of West Nile virus has killed more than two dozen bald eagles in Utah and thousands of water birds around the Great Salt Lake, state wildlife officials said on Tuesday.
At least 27 bald eagles have died this month in the northern and central parts of Utah ... Read More
The common cold virus (rhinovirus) is a tiny, almost round particle, containing the tightly packed genetic material surrounded by a protein shell (the virus capsid). Details on how the RNA is prepped to exit the capsid and effectively infect us have now been provided by scientists from the Max F... Read More
A noninvasive technology can accurately detect even low levels of malaria infection through the skin in seconds with a laser scanner that requires no dyes, diagnostic chemicals, or needles.
As reported in a preclinical study published this week in the Proceedings of the National Academy of Sc... Read More
All in all, 2013 was a bang-up year for science art. It seems the genre is gaining ground as more and more exhibits tackle the fascinating possibilities that exist at the intersection of science and art. 2014 seems to be continuing the trend with a wide array of notably longer exhibits. Enjoy! F... Read More
Several research groups, including a team led by geneticist Erika Sasaki and stem-cell biologist Hideyuki Okano at Keio University in Tokyo, hope to create transgenic primates with immune-system deficiencies or brain disorders. This could raise ethical concerns, but might bri... Read More
This image shows the nematode host Caenorhbaditis elegans encountering the bacterial pathogen S. marcescens. Natural selection imposed by the co-evolving pathogen led to the evolution and maintenance of bi-parental sex in the host population.
The host and the pathogen were experimentally co-e... Read More
A new imaging technique for studying the structure of a childhood disease, respiratory syncytial virus (RSV), could provide scientists with the information they need to develop new antiviral drugs and perhaps even a vaccine to prevent severe infections.
By the time they’re two years old, most... Read More
In addition to the known phenomenon by which some bacteria achieve resistance to antibiotics through mutation, there are other types of bacteria, known as “persistent bacteria”, which are not resistant to the antibiotics but simply continue to exist in a dormant or inactive state while exposed t...

Pioneering scientists and engineers are often overlooked in popular retrospectives commemorating the year’s departed. In particular, women in such fields tend to be given short shrift. To counter this regrettable circumstance, I present here a selection of 10 notable women in science who left us... Read More
Epidemiologists and the Centers for Disease Control say the flu virus has become widespread in 10 states, mainly in the Northeast and South, as the 2013-2014 flu season approaches its peak.
In its weekly survey of state epidemiologists, the CDC reported that cases of influenza were widespread... Read More
