Chemists turn metal catalysis on its head for a sustainable future

A research team used high-valent transition metal catalysts for an unconventional hydrogenation of carboxylic acid groups, common to biomass feedstocks. The high-valent catalysts showed good selectivity under mild conditions....

Slow motion makes soccer referees more likely to give a red card

Video assistant refereeing in soccer has to be used with caution. Researchers have shown that refs are more likely to give red when they see a foul committed in...

Researchers discover novel colistin resistance gene mcr-3 in Escherichia coli

A new mobile colistin resistance gene, mcr-3, has been discovered in E. coli of pig origin. The novel mcr-3 gene was discovered when a colistin-resistant Escherichia coli isolate tested...

Transcranial stimulation and/or physical therapy improves walking speed in Parkinson's disease

Noninvasive brain stimulation and physical therapy — alone or in combination — improve some measures of walking ability in patients with Parkinson’s disease (PD), concludes a clinical trial. Source:...

Astronomers detect orbital motion in pair of supermassive black holes

Images made with the continent-wide Very Long Baseline Array detect the orbital motion of two supermassive black holes as they circle each other at the center of a distant...

Older obese adults can benefit from moderate exercise

Moderate-intensity exercise can help even extremely obese older adults improve their ability to perform common daily activities and remain independent, according to researchers. Source: Science Link: Older obese adults...

Could humans ever regenerate a heart? A new study suggests the answer is 'yes'

A new study’s findings point to potential for tweaking communication between human genes and advancing our ability to treat heart conditions and stimulate regenerative healing. Source: Science Link: Could...

Night shifts may hinder body's ability to repair DNA damage

Night shift work may hinder the body’s ability to repair DNA damage caused by normal cellular processes, suggests a small study. Source: Science Link: Night shifts may hinder body's...

Odd properties of water and ice explained: Water exists as two different liquids

Scientists have discovered two phases of liquid water with large differences in structure and density. The results are based on experimental studies using X-rays. Source: Science Link: Odd properties...
