Scientists have reported that an experimental vaccine targeting one of the most common genetic drivers of pancreatic cancer, called mutant KRAS, is safe and generated a durable immune responses aimed at preventing the cancer.
A method based on computer vision algorithms similar to those used in facial recognition systems combined with visualization of only the diagnostically most relevant areas can mean a big breakthrough in malaria diagnostics, according to a new paper. Tablet computers can be utilized in viewing the images.
In this new method, a thin layer of blood smeared on a microscope slide is first digitized. The algorithm analyzes more than 50,000 red blood cells per sample and ranks them according to the probability of infection. Then the program creates a panel containing images of more than a hundred most likely infected cells and presents that panel to the user. The final diagnosis is done by a health-care professional based on the visualized images.
A ubiquitous skin fungus linked to dandruff, eczema and other itchy, flaky maladies in humans has now been tracked to even further global reaches—including Hawaiian coral reefs and the extreme environments of arctic soils and deep sea vents.
A review in the scientific journal PLOS Pathogens considers the diversity, ecology, and distribution of the fungi of the genus Malassezia in light of new insights gained from screening environmental sequencing datasets from around the world.
Scientists have mapped quantum tornadoes that swirl within tiny droplets of liquid helium, which confirms that helium nanodroplets are in fact the smallest possible superfluidic objects and opens new avenues to study quantum rotation.
Superfluid helium has long captured scientist's imagination since its discovery in the 1930s. Unlike normal fluids, superfluids have no viscosity, a feature that leads to strange and sometimes unexpected properties such as crawling up the walls of containers or dripping through barriers that contained the liquid before it transitioned to a superfluid.
Next year, American consumers will finally be able to purchase fuel cell cars and they are zero-emissions vehicles but, like current electric cars, not really, since the cars will run on hydrogen made from natural gas.
If you capture a hummingbird on high-speed video and slow it down, their wings thrum like helicopter blades as they hover near food. Their hearts beat 20 times a second and their tongues dart 17 times a second to slurp from a feeding station.
Researchers at
the NIH National Institute of Allergy and Infectious Diseases scientists have found that Middle East respiratory syndrome coronavirus (MERS-CoV) infection in marmosets closely mimics the severe pneumonia experienced by people infected with MERS-CoV, giving researchers the best animal model yet for testing potential treatments.
They used marmosets after predicting in computer models that the animals could be infected with MERS-CoV based on the binding properties of the virus.
New measurements of atomic-scale magnetic behavior in iron-based superconductors are challenging conventional wisdom about superconductivity and magnetism.
Water is abundant and so is sunlight, and using them to create hydrogen makes sense for a cleaner energy future, where biological systems powered by sunlight can manufacture hydrogen to use as fuel.
The way that plants produce hydrogen by splitting water has been poorly understood but answers are getting closer. A research team created a protein which, when exposed to light, displays the "electrical heartbeat" that is the key to photosynthesis.
The system uses a naturally-occurring protein and does not need batteries or expensive metals, meaning it could be affordable in developing countries.
Alzheimer's disease can be slowed and some of its symptoms curbed by punicalagin, a natural compound, found in pomegranate, according to a study in Molecular Nutrition and Food Research.
Alzheimer's affects up to 44.4 million people globally.
The two-year project headed by University of Huddersfield scientist Dr. Olumayokun Olajide also found that the painful inflammation that accompanies illnesses such as rheumatoid arthritis and Parkinson's disease could be reduced.
Humans don't want to live above the West Antarctic ice sheet but microbes can certainly live below it, according to a new study. Even half a mile below it.
The waters and sediments of a lake 2,600 feet beneath the surface of the West Antarctic ice sheet support "viable microbial ecosystems", according to recent results. Given that more than 400 subglacial lakes and numerous rivers and streams are thought to exist beneath the Antarctic ice sheet, such ecosystems may be widespread and may influence the chemical and biological composition of the Southern Ocean, the vast and biologically productive sea that encircles the continent.
The first direct observations of how facets form and develop on platinum nanocubes reveals that a nearly 150 year-old scientific law describing crystal growth breaks down at the nanoscale.
The researchers behind a new study used transmission electron microscopes and an advanced high-resolution, fast-detection camera to capture the physical mechanisms that control the evolution of facets – flat faces – on the surfaces of platinum nanocubes formed in liquids.
Understanding how facets develop on a nanocrystal is critical to controlling the crystal's geometric shape, which in turn is critical to controlling the crystal's chemical and electronic properties.
Researchers have developed a new process which will greatly simplify the process of sorting plastics in recycling plants by enabling automated identification of polymers and facilitating rapid separation of plastics for re-use.
