Four in five bird species cannot tolerate intense human pressures      (via sciencedaily.com)     Original source 

In a recent study, researchers found that 78% of the world's bird species do not thrive in the most modified human-dominated environments. These species are also most likely to have declining populations.

'Tug of war' tactic enhances chemical separations for critical materials      (via sciencedaily.com)     Original source 

Lanthanide elements are important for clean energy and other applications. To use them, industry must separate mixed lanthanide sources into individual elements using costly, time-consuming, and waste-generating procedures. An efficient new method can be tailored to select specific lanthanides. The technique combines two substances that do not mix and that prefer different types of lanthanides. The process would allow for smaller equipment, less use of chemicals, and less waste production.

Machine learning enables viability of vertical-axis wind turbines      (via sciencedaily.com)     Original source 

Researchers have used a genetic learning algorithm to identify optimal pitch profiles for the blades of vertical-axis wind turbines, which despite their high energy potential, have until now been vulnerable to strong gusts of wind.

Drawing inspiration from plants: A metal-air paper battery for wearable devices      (via sciencedaily.com)     Original source 

Drawing inspiration from the way plants breathe, a group of researchers has created a paper-based magnesium-air battery that can be used in GPS sensors or pulse oximeter sensors. Taking advantage of paper's recyclability and lightweight nature, the engineered battery holds promise for a more environmentally friendly source of energy.

How and why animals can live alongside humans      (via sciencedaily.com)     Original source 

New research suggests animals can thrive in human-dominated environments by being expert judges of risk. Researchers examined the behavior of great-tailed grackles, a bird species successfully invading much of urban North America, showing that the dispersing males shy away from risk, which is a characteristic the researchers show is well-suited to chaotic environments like cities. These findings provide unique insight into how and why animals and humans can coexist.

When did the chicken cross the road? New evidence from Central Asia      (via sciencedaily.com)     Original source 

An international team of scholars present the earliest clear archaeological and biomolecular evidence for the raising of chickens for egg production, based on material from 12 archaeological sites spanning one and a half millennia. The research indicates that the domestic chicken, now a staple in diets around the world, is not as ancient as previously thought.

Wound treatment gel fights the battle against antibacterial resistance      (via sciencedaily.com)     Original source 

Polymer-based hydrogels are used to treat skin ailments and in tissue engineering because of their ability to retain water, deliver drugs into wounds, and biodegrade. However, they are complicated to manufacture and not very resilient to external forces like rubbing against clothing, sheets, or wound dressings. Scientists have now created a hydrogel enhanced with the amino acid polylysine and blood plasma that is easier to synthesize, contains natural antibiotic properties, and promotes cell growth.

Researchers discover dual topological phases in an intrinsic monolayer crystal      (via sciencedaily.com)     Original source 

An international team working with single-atom thick crystals found TaIrTe4's transition between the two distinct topological states of insulation and conduction. The material exhibited zero electrical conductivity within its interior, while its boundaries remain conductive. The team's investigation determined that the two topological states stem from disparate origins. The novel properties can serve as a promising platform for exploring exotic quantum phases and electromagnetism.

Canada lynx historic range in US likely wider than previously thought      (via sciencedaily.com)     Original source 

A broader past could mean a brighter future for Canada lynx in the U.S., according to recent research. The study indicates that lynx might do well in the future in parts of Utah, central Idaho and the Yellowstone National Park region, even considering climate change and the lack of lynx in those areas now. Using a model validated by historic records, researchers first found that in 1900, Canada lynx had more suitable habitat in the U.S. than the few northern corners of the country where they are found currently. The study showed the elusive big cat likely roamed over a larger area in the Pacific Northwest, Rocky Mountains, Great Lakes region and parts of New England.

Cellphone compass can measure tiny concentrations of compounds important for human health      (via sciencedaily.com)     Original source 

Nearly every modern cellphone has a built-in compass, or magnetometer, that detects the direction of Earth's magnetic field, providing critical information for navigation. Now a team of researchers has developed a technique that uses an ordinary cellphone magnetometer for an entirely different purpose -- to measure the concentration of glucose, a marker for diabetes, to high accuracy.
