A 2-in-1 punch for taking out cancer

A new study by bioengineers at Brigham and Women's Hospital demonstrates the effectiveness of combination therapies in eliminating cancer cells. By pairing chemotherapy drug docetaxel with a targeted PI3K inhibitor, researchers achieved greater tumor inhibition and eliminated evidence of resistance.

Lives in the balance: Why do we hold onto potentially harmful, disease-causing mutations?

A recent study found that balancing selection can increase the frequency of harmful mutations in non-HLA genes within the MHC region. This mechanism may contribute to the prevalence of heritable diseases. The research team used DNA sequencing data from 6,500 individuals to test this hypothesis.

Researchers find human development's first gear

A team of researchers at Oxford University has identified four genes that play a crucial role in early human development. These genes, known as Argfx, Leutx, Dprx and Tprx, are activated for an extremely brief period, when the embryo is a tiny ball of 8-16 cells. They then switch off, controlling the 'first gear' of embryonic growth.

Lost hormone is found in starfish

Researchers discovered a lost hormone in starfish that is linked to human sexual maturity and evolution. The study found that the evolutionary history of the hormone gonadotropin-releasing hormone (GnRH) is written in the genes of the starfish, with two GnRH-like hormones found in both humans and fruit flies.

The July 2016 issue of Geology is now online

The July 2016 issue of Geology features studies on pre-Mississippian tectonic affinity across the Canada Basin-Arctic margins, as well as hydrothermal alteration of seafloor peridotites. Researchers also investigate recent volcanic resurfacing of Venusian craters and cyanobacterial fossilization in Ediacaran siliciclastic environments.

Lionfish invading the Mediterranean Sea

A recent study published in Marine Biodiversity Records reveals that lionfish have colonized almost the entire southeastern coast of Cyprus within a year, thanks to rising sea temperatures. The invasive species can outcompete native fish and reduce biodiversity in the area.

Could growing Internet use inspire more democratic uprisings?

A new study found that internet users who primarily accessed the web for entertainment purposes, such as watching cat videos, were less likely to demand democracy in their countries. In contrast, those who used the internet for news and sharing political opinions were more likely to support democratic reforms. The researchers suggest t...

Doing the math on Zika and sex

A University of Miami research team created a mathematical model to investigate the role of sexual transmission in the spread and control of Zika. The study found that mosquito control remains the most important mitigation method, but sexual transmission increases the risk of infection and prolongs outbreaks.

See and sort: Developing novel techniques to visualize uncultured microbial cell activity

Researchers developed novel techniques to visualize uncultured microbial cell activity using BONCAT, a high-throughput and cost-effective approach. This method identifies individual active cells and clusters within microbial communities, providing insights into the ecological function of microorganisms.

Non-healing tissue from diabetic foot ulcers reprogrammed as pluripotent stem cells

A study by researchers at Tufts University successfully reprograms cells from diabetic foot ulcers into pluripotent stem cells, which can be turned into various cell types important for wound healing. The findings provide a new target for treatment and may lead to the development of more effective therapies for non-healing wounds.

Foot wrap offers alternative to medication for patients with restless legs syndrome

A pilot study published in The Journal of the American Osteopathic Association found an adjustable foot wrap to be significantly more effective than standard pharmaceutical treatment for restless legs syndrome. The device caused a 1.4 times increase in sleep for those with moderate to severe symptoms.

Household fuels a major contributor to Beijing's infamous air pollution

A new study found that household use of coal and dirty fuels in households is a major contributor to Beijing's notorious air pollution. Eliminating these emissions could reduce particulate levels by up to 22%. Regional efforts are crucial to address this issue, as individual cities may not have control over surrounding regions.

Getting a grip on slippery cell membranes

Researchers at WPI and Penn used laboratory experiments and computational modeling to study the interactions between molecular motors, filaments, and membranes. They found that a single myosin-1 molecule is not enough to generate sufficient force against slippery membranes, requiring up to 124 molecules working together.

Household fuels exceed power plants and cars as source of smog in Beijing

New research reveals that households in Beijing contribute significantly to outdoor pollution, producing 50% of black carbon emissions and 69% of organic carbon emissions. The use of solid fuels for heating and cooking in homes is a major source of ill health in China, with air pollution ranking as a leading cause of premature death.
