Phys.org / Narrow ultrasonic beam enables stable 3D levitation six times farther than before
Scientists have developed a new acoustic levitation technique using an ultrasonic beam capable of levitating and moving small objects in midair over distances of up to 40 cm (16 inches), six times farther than previously ...
Phys.org / Emperor penguin colonies reveal decades-long resilience and flexible breeding sites
With their charming waddles, heat-conserving huddles and tuxedo-like plumage, emperor penguins are among the world's most recognizable animals. Recent satellite surveys estimate that hundreds of thousands of the flightless ...
Phys.org / Dog-friendly dining isn't just a trend, it's good for business, new research shows
Restaurants that go beyond simply allowing dogs on patios by offering dedicated menu items for them can significantly boost customer traffic, spending and word-of-mouth, according to new research from Toronto Metropolitan ...
Medical Xpress / 'Supportive' brain cells may actively drive cognitive decline
Brain cells that produce the protective coating around nerve fibers can become dysfunctional with age and may actively contribute to cognitive decline, according to new research.
Phys.org / Strategic irrigation stress can lift lucerne seed yield and returns
More water does not necessarily produce more alfalfa seed. A five-year trial near Keith, South Australia, found that strategically delaying irrigation until plants showed early signs of leaf drop generally increased seed ...
Phys.org / Geomimicry offers a new framework for engineering sustainable materials
When engineers look to nature for inspiration, they often turn to living systems. The flight of birds has influenced aircraft design, gecko feet inspired new adhesives and lotus leaves led to the development of self-cleaning ...
Phys.org / Machine learning method uncovers hidden patterns in DNA methylation
In a study recently published in Nature Communications, researchers from Berlin, Potsdam, and Jena present a new method for analyzing the epigenome. The machine-learning method identifies differentially methylated DNA regions ...
Phys.org / Quantum computer microscope is set to significantly improve electron microscopy
Electron microscopes are used wherever particularly small details need to be imaged. But from a strictly physical point of view, every electron in a conventional electron microscope represents a missed opportunity: If all ...
Tech Xplore / Purple fabric beats the heat, reflecting 87.6% of sunlight and cooling simulated skin
A new purple cooling fabric developed by Chinese and Australian researchers could help people stay cooler during scorching summer days without having to resort to wearing white.
Medical Xpress / New approach cuts sepsis diagnosis from days to hours
Sepsis, a life-threatening condition that stems from the body trying to fight off an infection, plagues more than 1.5 million patients a year in the U.S. alone, with one in three deaths recorded in hospitals attributed in ...
Phys.org / Narwhals help researchers uncover unique data from the deepest East Greenland fjords
They live in some of the most inaccessible waters on Earth, where ocean temperatures hover around freezing. Because they move through areas that humans rarely reach, they have been able to help researchers with a special ...
Phys.org / Diverse portfolio of protected areas key to Mexican conservation efforts
In 2020, Mexico joined 150 nations committing to protect 30% of its territory by 2030 as part of the global 30x30 initiative. More than halfway through the decade, there is ongoing debate about how to effectively expand protected ...
