How invasive Egyptian geese exploit food sources and carry parasites‎

The Egyptian goose, native to Africa, is considered an invasive species of Europe-wide significance. Researchers from the Senckenberg Biodiversity and Climate Research Center and Goethe University Frankfurt spent four years investigating the ecological and economic impacts of its expansion.

Stretching boosts thermal and electrical conductivity in new nanocomposite‎

A joint research team led by professors Seunghyun Baik and Joonmyung Choi from the School of Mechanical Engineering at Sungkyunkwan University (SKKU) has developed a new nanocomposite material whose electrical and thermal conductivities increase as it is stretched. The team successfully applied it to stable heat dissipation for foldable phones.

Hit songs fade faster from the Billboard charts than albums‎

Favorite songs can stay with us for a lifetime, but their shelf life on the music charts is fleetingly short. Tracks that shoot up the U.S. Billboard charts may flood the airwaves for a short while, but just a few weeks later, they have vanished. The outlook for albums is far more enduring, according to a new paper published in the journal Royal Society Open Science.

Blue-light labeling uncovers unexpected protein partners of folded DNA structures‎

DNA can be more than just a double helix. When four strands are folded into a compact bundle, they form a G-quadruplex (G4). These bundles form in guanine-rich regions across the genome, including telomeres at the ends of chromosomes and the control regions of genes, where the proteins that dock onto them help decide which genes are switched on. G4 does not act the same way everywhere. What it does depends on where it forms and which proteins bind to it. This is why understanding the interactions surrounding G4 is so important.

Why older people value quiet spaces with people nearby‎

Older adults enjoy spending time in peaceful, green spaces, but not in complete isolation. For her Ph.D. research, Anne Grave investigated which characteristics are most important for the ideal living environment for people age 70 and older. Her findings show that relaxation occurs where tranquility, nature, safety and the presence of other people come together. By gathering input directly from older adults, she provides designers of public spaces with valuable insights into the needs of older residents.

What Europe's EU Inc. framework for boosting competitiveness can and should learn from startup fraud in the US‎

The European Parliament and the Council of the European Union are currently debating EU Inc., draft legislation seeking to establish a single set of rules for starting, operating and growing a business across EU member states. The proposed framework is designed to make business registration and operation within the EU faster, easier and more harmonized.

El Niño and tropical Atlantic warming could offer early warning of extreme heat in the Amazon‎

El Niño and warming in the tropical Atlantic could help provide advance warning of extreme heat in the Amazon, with some signals appearing as much as seven months earlier, new research has found. Researchers from the ARC Center of Excellence for the Weather of the 21st Century and the National Institute of Space Research in Brazil studied how major patterns of natural climate variability influence temperature and rainfall extremes across the Amazon Basin.

A 2-in-1 approach captures toxic metals and recovers rare earth elements from wastewater‎

We generally throw away a broken camera lens, earphones or an old phone that has stopped working and is beyond repair because they seem useless when they no longer function. However, these objects contain rare earth elements (REEs) that have applications in magnets, superconductivity, optics and batteries, among others. When these objects end up in water, recovering REEs becomes difficult.

'Let me explain': Corporate disclosures can take a circuitous route‎

The shortest distance between two points is a straight line, but sometimes taking the long way home can have advantages.

Webb captures commotion from nebula's stellar jets‎

The NASA/ESA/CSA James Webb Space Telescope has unveiled numerous stars formerly hidden by clouds of dust in a stellar nursery known as NGC 7129—a cauldron of cosmic creation, 3,300 light-years from Earth. Webb captured infrared light, which pierces through the dense matter that scatters or absorbs other types of light. This region, rife with stellar objects in different stages of their lives, offers an opportunity to explore how stars shape their surroundings.
