How bacteria hunt other bacteria

Researchers studied how Bdellovibrio bacteriovorus tracks down prey using high-resolution video microscopy. The study found that the bacterial predator uses hydrodynamic flow fields generated by its own swimming movements and those of its prey to bring them in close proximity, increasing the chances of a successful attack.

Marathon running may cause short-term kidney injury

A recent Yale-led study found that marathon running can cause short-term kidney injury in runners, with 82% of participants showing signs of Stage 1 Acute Kidney Injury after the event. The researchers attribute this to sustained rises in core body temperature, dehydration, and decreased blood flow to the kidneys.

Chlamydia: How bacteria take over control

Researchers from the University of Würzburg discovered that Chlamydia trachomatis influences mitochondria to prevent programmed cell death, allowing the bacteria to replicate. The study found that miR-30c-5p microRNA is increased in infected cells, downregulating tumor suppressor protein p53 and promoting mitochondrial division

How a young-looking lunar volcano hides its true age

New research from Brown University suggests that lunar volcano Ina is actually around 3.5 billion years old, not within the past 100 million years as previously thought. The feature's youthful appearance was attributed to its porous surface, created by magmatic foam, which hides regolith buildup and skews crater counts.

To be or not to be ... an entrepreneur

Research finds that incorporated business owners exhibit greater self-esteem, engage in illicit activities, and are more likely to come from high-earning families. In contrast, unincorporated business owners have manual skill requirements and lower salaries before entrepreneurship. Incorporated entrepreneurs earn significantly higher m...

Meet your new electronic trauma intervention

A new study found that playing a highly visual-spatial computer game like Tetris can help prevent intrusive memories after a traumatic event. The intervention, which took just 20 minutes, reduced symptoms of acute stress disorder and post-traumatic stress disorder by 62% in patients waiting for emergency care.

Mustard seeds without mustard flavor: New robust oilseed crop can resist global warming

Scientists have developed a new oilseed crop that is more resistant to heat, drought, and diseases than oilseed rape. The breakthrough technology keeps bitter defense compounds out of the seeds while maintaining them in the rest of the plant, enabling cultivation in areas previously unsuitable for oilseed crops.

Longer telomeres may shield mice from age-related human diseases

A recent study found that longer telomeres in mice may shield them from age-related human diseases. Researchers used mice with shortened telomeres to examine a genetic defect causing an age-associated congenital heart disease in humans. The findings suggest that decreasing telomere length contributes to the onset of age-related diseases.

Evolving 'lovesick' organisms found survival in sex

A new theory suggests that sexual reproduction evolved as a way to resist disease-causing microbes and adapt to constantly changing environments. Researchers used computer simulations to demonstrate the benefits of sex in nematode worms co-evolving with a highly pathogenic bacterium, providing evidence for the Red Queen theory.

Zika virus protein mapped to speed search for cure

A recent study by Indiana University researchers has mapped a key protein of the Zika virus, enabling the analysis of existing drugs and compounds that can disrupt its spread. The study's findings offer hope for finding effective treatments against the disease, which causes birth defects and neurological disorders in infants and adults.

A new test to rapidly identify worldwide TB infections

A new rapid blood test to diagnose and quantify the severity of active TB cases has been developed by a team of researchers from Arizona State University. The NanoDisk-MS assay can detect minute blood levels of two proteins that are released only during active infections, providing faster results than current tests.

How randomness helps cancer cells thrive

A study published in Nature Genetics reveals that large regions of the human genome have built-in variability in reversible epigenetic modifications, which enables cancer cells to proliferate and adapt. This variation can make cancer cells more resistant to chemotherapy and treatment.

Farming becoming riskier under climate change

Climate change will make farming more difficult due to reduced planting windows and increased drought risk, affecting crop yields and food security. The University of Illinois study forecasts that the typical planting window for corn will no longer be workable, with April and May being too wet to work fields in most parts of Illinois.
