From one stem cell to many differentiated body cells: Scientists have now published a comprehensive lineage tree of a whole adult animal. This was made possible by a combination of RNA and computational technologies.
High-precision three-dimensional surveying of 21 different species of trees has revealed a yet unknown cycle of subtle canopy movement during the night. The 'sleep cycles' differed from one species to another. Detection of anomalies in overnight movement could become a future diagnostic tool to reveal stress or disease in crops.
New research indicates that belimumab, a monoclonal antibody therapy that targets a component of the immune system, provides considerable benefits to patients with systemic lupus erythematosus (SLE), a predominately female, chronic inflammatory disease that can affect virtually any organ.
Little is still known about the exact causes of irritable bowel syndrome. An international team has provided initial clues about the organic triggers of the disease, which affects an estimated one out of six people.
The vampire bat prefers to feed on domestic animals such as cows and pigs. When it does so, there is a risk of transmission of pathogens. Now, a new study describes a new DNA method to efficiently screen many vampire bat blood meal and fecal samples with a high success rate and thereby determine which animals the vampire bats have fed on blood from.
New research has shown that carefully structured light and matching arrangements of metal nanostructures can be combined to alter the properties of the generated light at the nanometer scale. The teams have shown that the efficiency of nonlinear optical fields generated from the oligomers is strongly influenced by how the constituents of the oligomer constituents are illuminated by structured light.
Epidemiologists and geologists have found associations between esophageal cancer and soils where lead is abundant, lung cancer and terrains with increased copper content, brain tumor with areas rich in arsenic, and bladder cancer with high cadmium levels. These statistical links do not indicate that there is a cause-effect relationship between soil type and cancer, but they suggest that the influence of metals from the earth's surface on the geographical distribution of tumors should be analyzed.
Cancer immune cell therapy has made headlines with astounding successes like saving former US President Jimmy Carter from brain cancer. But immunotherapy has also had many tragic flops. Researchers working to optimize the innovative treatment have implanted a genetic switch that activates T-cells when they are inside of tumors. Remote-control light waves resembling those used in a TV remote combine with gold nanorods to flip the switch.
A new recycling process turns discarded hard disk drive magnets into new magnet material in a few steps, and tackles both the economic and environmental issues typically associated with mining e-waste for valuable materials.
Researchers have shown that adenovirus binds to a specific type of carbohydrate that is overexpressed on certain types of cancer cells. The discovery opens up new opportunities for the development of virus-based cancer therapy.
An international team of researchers from Hong Kong, Singapore, Korea and the United States has demonstrated that nanoscale (300 nm) single-crystalline and polycrystalline diamond needles could flex and stretch by as much as 9% without breaking, then return to their original configuration. The team’s results, published in the journal Science, could open the door to [...]
An international team of paleontologists from the Natural History Museum, London, the University of Birmingham and Virginia Tech has formally given an ancient carnivorous reptile a name, over several decades since its fossils were found in Tanzania. The formal species description of Mandasuchus tanyauchen is published in a special memoir of the Journal of Vertebrate [...]
The NASA/ESA Hubble Space Telescope was launched into orbit by a space shuttle on April 24, 1990. It was the first space telescope of its kind, and has surpassed all expectations, providing a quarter of a century of discoveries, stunning images and outstanding science. To celebrate its 28th year in orbit, some of Hubble’s precious [...]
According to a review of more than 460 previous studies, ibuprofen and other nonsteroidal anti-inflammatory drugs alone or in combination with paracetamol (acetaminophen) are better at easing dental pain. “What we know is that prescribing narcotics should be a last resort,” said study co-author Dr. Anita Aminoshariae, from the Department of Endodontics in the School [...]
