A new study by an international team of scientists reveals the exact timing of the onset of the modern monsoon pattern in the Maldives 12.9 million years ago, and its connection to past climate changes and coral reefs in the region. The analysis of sediment cores provides direct physical evidence of the environmental conditions that sparked the monsoon conditions that exist today around the low-lying island nation and the Indian subcontinent.
A new study, which followed 180 pre-term infants from birth to age seven, found that babies who were fed more breast milk within the first 28 days of life had had larger volumes of certain regions of the brain at term equivalent and had better IQs, academic achievement, working memory, and motor function.
The algae C. reinhardtii uses a novel system for releasing an interrupting sequence from a protein -- a technique that may be useful for protein purification.
New research, using computer models of wave chaos, has shown that three-dimensional tangled vortex filaments can in fact be knotted in many highly complex ways.
Researchers at ETH Zurich have developed a lattice structure capable of absorbing a wide range of vibrations while also being useful as a load-bearing component -- for example, in propellers, rotors and rockets. It can absorb vibrations in the audible range, which are the most undesirable in engineering applications.
People living with HIV who naturally produce broadly neutralizing antibodies (bNAbs) that may help suppress the virus have different immunological profiles than people who do not, NIAID-supported researchers report. While bNAbs cannot completely clear HIV infections in people who already acquired the virus, scientists believe a successful preventive HIV vaccine must induce bNAbs. Defining how to safely replicate these attributes in HIV-uninfected vaccine recipients may lead to better designed experimental vaccines to protect against HIV.
A portable production system, designed to manufacture a range of biopharmaceuticals on demand, has been developed by researchers at MIT, with funding from the Defense Advanced Research Projects Agency. In a paper published in the journal Nature Communications, the researchers demonstrate that the system can be used to produce a single dose of treatment from a compact device containing a small droplet of cells in a liquid.
In a study published in Scientific Reports, scientists discovered impressive abundance and diversity among the creatures living on the seafloor in the Clarion-Clipperton Zone -- an area in the equatorial Pacific Ocean being targeted for deep-sea mining. The study found that more than half of the species they collected were new to science, reiterating how little is known about life on the seafloor in this region.
Scientists have developed a new method of measuring the activity of disease-causing mutations in the LRRK2 gene, a major cause of inherited Parkinson's disease.
Many deadly diseases that afflict humans were originally acquired through contact with animals. New research published in ASM's Applied and Environmental Microbiology shows that pathogens can also jump the species barrier to move from humans to animals. The study, that will publish July 29, shows that green monkeys in The Gambia acquired Staphylococcus aureus from humans.
