Nanoparticle That Mimics Red Blood Cell Shows Promise as Vaccine for Bacterial Infections

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.

25 years of DNA on the computer

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

Lack of drug data 'extreme concern'

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

Added Laser Makes Force Microscope 3D

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...

What can slime molds offer computing?

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

Mathematical modelling disproves long-held view of bacterial cell cycle

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

Genetically identical bacteria can behave in radically different ways

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

Chemistry: A festive ferment

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

What's this?

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

New vaccine from University of Iowa protects against lethal pneumonia caused by staph bacteria

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

West Nile Virus Blamed for Death of Bald Eagles in Utah

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

Infection with the common cold virus: scientists reveal new insights

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

Vapor "Nanobubbles" Detect Malaria Through Skin

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

Start 2014 in Style With These ScienceArt Exhibits

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

What to expect in 2014 - Nature takes a look at what is in store for science in the new year

Transgenic monkeys
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

Nematode Host Meets Bacterial Pathogen

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

Imaging Technique Could Lead to RSV Vaccine

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

Hebrew U. researchers reach breakthrough on understanding how persistent bacteria are able to avoid antibiotics

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...

Gone in 2013: A Tribute to 10 Remarkable Women in Science

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
