'Check your ingredients': A new blueprint for using Fermi's 'Golden Rule'

Underpinning much of modern technology, from smartphones to scanning tunneling microscopes to particle colliders, is Fermi's Golden Rule. Named for 20th-century Italian American physicist Enrico Fermi (but actually discovered by British physicist Paul Dirac), the rule is a formul

Self-propelled microparticles scrub stubborn biofilms, improving wound care and instrument

Newly developed microparticles can infiltrate stubborn bacterial matrices and release tiny oxygen bubbles to clean surfaces and wounds more efficiently than hydrogen peroxide or other cleaning agents alone, researchers at the University of Illinois Urbana-Champaign report. In two

Peering into materials down to the nanoscale in the COCOON lab

A new Tufts University imaging facility is doing something that most microscopy centers in the world cannot: allowing scientists to examine a butterfly wing, a living tissue or a microchip and reveal its physical structure, molecular chemistry and elemental composition across eve

Pacific gray whales facing ‘catastrophic’ die-off as climate crisis hits food supply

Trump administration urged to relist a species in ‘very, very serious trouble’ under Endangered Species ActClimate change is driving a gray whale “catastrophic mortality event” in the Pacific Ocean as melting sea ice depletes food sources and the animals starve, environmental gro

If so many people live with toxoplasmosis, how dangerous is this brain parasite really? Sh

About 1 in 3 people worldwide have been infected with a microscopic parasite called Toxoplasma gondii—or simply "toxo"—which can cause toxoplasmosis. After the initial infection, toxo settles into our muscles and brains, where it can remain for life.

Moderate warming rewires one-third of microalga's genes, study finds

Researchers have demonstrated for the first time that the microalga Chlamydomonas reinhardtii alters the activity of about one-third of its protein-coding genes in response even to moderate temperature changes. The study, published in the journal The Plant Cell, points to far-rea

Deep-sea life has a secret food source scientists never expected

Scientists discovered that extreme deep-sea pressure squeezes valuable nutrients out of sinking organic particles, providing an unexpected food source for ocean microbes. The finding could rewrite our understanding of both deep-ocean ecosystems and how carbon is stored on Earth.

How simple changes to PowerPoint presentations can make a big difference for learners

Microsoft PowerPoint has become the default tool for presenting learning materials in classrooms, universities, corporate training programs, webinars and remote learning environments. But is it being used effectively? This question arises because learners face a major challenge.

Machine learning calibration of biosensors for microcystin toxin monitoring in freshwater

Portable screen-printed carbon electrode (SPCE) biosensors offer a rapid, low-cost way to detect microcystin-lysine-arginine (MC-LR), an extremely potent toxin produced by cyanobacteria during harmful algal blooms in freshwater. Even at low concentrations, MC-LR can damage the li

Shrimp feeding behavior observed under simulated microgravity

The Space Aquaculture Project at Okayama University of Science is an ambitious research initiative aimed at cultivating fish and crustaceans on the moon and Mars, which are expected to serve as food production bases for future space exploration. The project ultimately seeks to im

New 3D thermal cloak hides objects from heat in any direction

Researchers have designed and built the first 3D device that can make objects invisible to heat, an advance that could transform how we protect sensitive electronics, manage heat in microchips and shield equipment from thermal detection.
