How superbug A. baumannii survives metal stress and resists antibiotics

Researchers at Macquarie University have discovered how superbug A. baumannii survives harsh environments and resists antibiotics by exploiting its strong drug pumps to expel essential metals from the cell. Disrupting this master regulatory protein, DksA, breaks the pumping system and allows for control of the bug.

African smoke over the Amazon

Research reveals that soot particles in the Amazon rainforest come primarily from African bushfires, not regional fires. This discovery highlights the significant role of atmospheric transport in distributing pollutants across continents.

You’ve got some nerve

Researchers developed a new metric to analyze the relationship between nerve density and oral cancer progression. Normalized nerve density was found to be associated with poor survival rates for patients with tongue cancer, highlighting its potential as a tool for identifying aggressive tumors.

When does the gender gap start in the computer science field?

A new UH study reveals that third-grade girls are initially enthusiastic about coding and computer science, with equal interest and confidence as boys. However, by middle school age, negative stereotypes and a decrease in confidence among girls become prevalent, limiting their participation in these fields.

Lockdowns and vaccines: a balancing act

A new study investigates lockdowns and vaccines' complementary or substitutive roles in mitigating COVID-19's effects. The researchers found that vaccinations should be relaxed after substantial vaccination rates, but vastly different policies may be optimal depending on parameters.

Joro spiders aren’t scary. They’re shy

A new study from the University of Georgia found that Joro spiders, despite their intimidating appearance, are gentle giants, mean no harm to people or pets. They remain immobile for over an hour after a disturbance, unlike other spider species that resume normal activities within a minute and a half.

“Warm Ice Age” changed climate cycles

Researchers from Heidelberg University identified a pivotal step in the Earth's later climate development, finding that a warm ice age around 700,000 years ago led to changes in global climate rhythms. This 'warm ice age' caused accumulation of excess continental ice, resulting in prolonged and far-reaching glaciation.

Cognitive training helpful for some but not a panacea for fall prevention

A new study found that cognitive training, specifically speed of processing training, reduced the risk of falling among older adults at high risk of falls by 31% over 10 years. However, it had no effect on those at low risk of falling. Cognitive training may enhance physical-based interventions to reduce falls for some individuals.
