Changing climate impacts biodiversity in protected areas globally

A recent study provides insights for developing climate-smart conservation strategies by looking at the global network of protected areas, evaluating potential for shifts in where plants and animals occur due to climate change. Findings point to the need for strategic conservation plans that transcend international borders to protect at-risk species.

Better residents' health after switch to electric buses

The health of residents living alongside a bus route in Gothenburg, Sweden, became considerably better when hybrid buses were replaced by buses fully powered by electricity. Along with the noise levels there was a reduction of fatigue, day time sleepiness and low mood, a new study shows.

Research finally answers what Bronze Age daggers were used for

Analysis of Bronze Age daggers has shown that they were used for processing animal carcasses and not as non-functional symbols of identity and status, as previously thought. A revolutionary new method has enabled the world's first extraction of organic residues from ten copper-alloy daggers.

Light-infused particles go the distance in organic semiconductors

Polaritons offer the best of two very different worlds. These hybrid particles combine light and molecules of organic material, making them ideal vessels for energy transfer in organic semiconductors. They are both compatible with modern electronics but also move speedily, thanks to their photonic origins.

Stress, anxiety and depression during pregnancy may hinder toddler's cognitive development

Women's elevated anxiety, depression and stress during pregnancy altered key features of the fetal brain, which subsequently decreased their offspring's cognitive development at 18 months. These changes also increased internalizing and dysregulation behaviors, according to a new study. Researchers followed a cohort of 97 pregnant women and their babies. The findings further suggest that persistent...

Unlocking a cure for carbon monoxide poisoning

Treatment options are limited for those suffering from carbon monoxide poisoning. Researchers have designed a small molecule that shows promise as a potential treatment that could rapidly clear carbon monoxide from the blood.

'Eye-catching' smartphone app could make it easy to screen for neurological disease at home

Researchers have developed a smartphone app that could allow people to screen for Alzheimer's disease, ADHD and other neurological diseases and disorders -- by recording closeups of their eye. The app uses a smartphone's built-in near-infrared camera and selfie camera to track how a person's pupil changes in size. These pupil measurements could be used to assess a person's cognitive condition.

New model for antibacterial mechanism

Biologists have discovered an aberrant protein that's deadly to bacteria. This erroneously built protein mimics the action of aminoglycosides, a class of antibiotics. The newly discovered protein could serve as a model to help scientists unravel details of those drugs' lethal effects on bacteria -- and potentially point the way to future antibiotics.

A new mutation behind synucleinopathies

Scientists have carried out an extensive study of a newly discovered mutation that can uncover new insights into the molecular basis of pathology formation in a family of disorders that includes Lewy body dementia and Parkinson's disease.
