New treatment can halve hospital stays for some patients with heart infection

A new treatment has been found to significantly reduce hospital stays for patients with heart infections by halving the duration of intravenous antibiotic treatment. The POET trial showed that giving patients oral antibiotics after at least ten days of intravenous treatment was as effective and safe as continued intravenous treatment, ...

If military robot falls, it can get itself up

Scientists at U.S. Army Research Laboratory and Johns Hopkins University Applied Physics Laboratory develop software to analyze a robot's ability to self-right from any overturned orientation. The team evaluates the Advanced Explosive Ordnance Disposal Robotic System and determines it can right itself on level ground regardless of its ...

Treating inflammatory bowel disorder by delivering microRNAs

Osaka University researchers successfully delivered microRNAs to immune response cells in inflamed intestinal tracts using a super carbonate apatite (sCA), reducing inflammatory cytokines. The study showed that sCA could be used to treat a wide range of immunity and allergic disorders caused by immune responses.

Protein modifications pointing to cancer

Scientists have developed a method to investigate all proteins in tissue samples that are modified by ADP-ribosylation, a stress response pathway. This allows for conclusions to be drawn about activated signaling pathways and potentially leads to new diagnostic and therapeutic possibilities for cancer and other diseases.

The math of malaria

A mathematical model for malaria shows that competition between parasite strains within a human host reduces the odds of drug resistance developing in high-transmission settings. The model reveals how once a drug-resistant strain becomes established, it will spread faster in high-transmission areas than in low-transmission areas.

Wilder wildfires ahead?

Researchers at UCSB and NCAR find that climate change is affecting the connection between El Niño and wildfires, leading to more extreme and frequent fires. As the Earth warms, El Niño events are expected to have a larger impact on fire risk in California and other fire-prone regions.

Disentangling the relationships between cultural traits and other variables

A team of researchers identified three sources of non-independence in cultural variables: phylogenetic non-independence, spatial autocorrelation, and covariation. By controlling for these factors, they found that parasites have no more explanatory power for cultural traits than other environmental factors like biodiversity and climate.
