Phys.org / Caterpillars hear through tiny body hairs, which could inspire improved microphones
No ears, no problem. The tobacco hornworm caterpillar, a common garden pest, can actually detect airborne sound via microscopic hairs on its body, according to a team of faculty and graduate students at Binghamton University. ...
Phys.org / Framework sets new benchmarks for 3D atom maps in amorphous materials
Researchers at the California NanoSystems Institute at UCLA published a step-by-step framework for determining the three-dimensional positions and elemental identities of atoms in amorphous materials. These solids, such as ...
Phys.org / Microplastics found in a third of surveyed fish off the coasts of remote Pacific Islands
A third of fish living in the remote coastal waters of the Pacific Island Countries and Territories are contaminated with microplastics, with especially high rates in Fiji, according to an analysis published in PLOS One by ...
Phys.org / Cross-border pollution tracking reveals unequal distribution of risk and responsibility
Microscopic airborne particles known as PM2.5 contribute to 100,000 premature deaths in the United States each year. A new University of Notre Dame study finds that 40% of these deaths can be attributed to pollution that ...
Phys.org / Changing land use can increase threat of animal‑to‑human disease spread
Changes to land use can directly heighten the risk of diseases spreading from animals to humans, new University of Stirling–led research has shown. The study, led by Dr. Adam Fell of the University's Faculty of Natural ...
Phys.org / Capturing the moment of organelle handoff inside living cells
For the first time, researchers have directly visualized how newly formed cellular organelles leave the endoplasmic reticulum (ER) and transition onto microtubule tracks inside living cells. This new finding reveals that ...
Phys.org / Residents from strongly blue or red counties favor like-minded destinations for everyday travel, analysis finds
A new analysis of 471 U.S. counties has found that, for everyday travel, people from counties with particularly strong political leanings—whether liberal or conservative—are more likely to visit like-minded destinations. ...
Phys.org / Plant mothers send molecular 'text messages' to pollen
Small RNAs are short RNA molecules that help determine which genes in a cell are switched on or off. Until now, it was assumed that the small RNAs necessary for pollen development originate in the pollen itself and in the ...
Phys.org / Cryoelectron tomography reveals paracrystalline architecture of proteasome storage granules
Cells organize their molecules into distinct functional areas. While textbooks usually refer to membrane-bound organelles such as mitochondria and cell nuclei, recent studies have also revealed organelles without membranes. ...
Phys.org / AI bosses are creating a new problem for gig workers
For millions of gig workers driving for companies such as Uber Eats, DoorDash and Deliveroo, there is no human manager to call, no supervisor to appeal to and no office to walk into. Decisions about pay, performance, penalties ...
Phys.org / Unprecedented 3D views of sensory cells accelerate hearing research
The cochlea is the spiral-shaped structure within the inner ear responsible for our sense of hearing. To fully understand hearing functions and open the door to new hearing loss treatments, scientists require intricately ...
Phys.org / New ABF crystal delivers high-performance vacuum ultraviolet nonlinear optical conversion
Vacuum ultraviolet (VUV, 100–200 nm) light sources are indispensable for advanced spectroscopy, quantum research, and semiconductor lithography. Although second harmonic generation (SHG) using nonlinear optical (NLO) crystals ...
