New research uncovers how microbes shape ecosystem resilience‎

Most people think of microbes in simple terms: Some make you sick, while others help keep you healthy. But microbes' influence stretches far beyond human bodies. These astonishingly complex organisms regulate the health of forests, oceans and grasslands and determine how ecosystems respond to environmental change.

Some glaciers can suddenly surge forward—with dangerous consequences‎

It's difficult to forget standing in front of a glacier that is advancing toward you, towering ice pillars constantly cracking as they inch forward. The motion is too slow to see in real time but is obvious from one day to the next.

Quantum research in two ways: From proving someone's location to simulating financial markets‎

Quantum physics may sound abstract, but Ph.D. candidates Kirsten Kanneworff and David Dechant show that quantum research can also be very concrete. Together, they are investigating how quantum technology can change the world. While Kanneworff worked in the lab to study how quantum optics can be used to prove someone's location, Dechant focused on quantum computing for dynamic systems, such as the financial world. The two researchers are defending their doctoral theses this week.

When consent meets reality: How young men navigate intimacy‎

A new study suggests that young men overwhelmingly support affirmative sexual consent in principle—yet often find its verbal implementation difficult in practice. The research, led by scholars at Columbia University's Mailman School of Public Health and Melbourne University's Department of General Practice and Primary Care, explores how young heterosexual men interpret and navigate consent during real-world sexual encounters.

How a key receptor tells apart two nearly identical drug molecules‎

G-protein-coupled receptors (GPCRs) are one of the largest families of cell surface proteins in the human body that recognize hormones, neurotransmitters, and drugs. These receptors regulate a wide range of physiological processes and are the targets of more than 30% of currently marketed drugs. The histamine H1 receptor (H1R) is one such GPCR subtype that plays a key role in mediating allergic reactions, inflammation, vascular permeability, airway constriction, wakefulness, and cognitive functions in the human body. While antihistamines primarily target H1R, current drugs can exhibit limited therapeutic efficacy, prompting researchers to look at H1R ligands from new perspectives.

Polluting the environment for all eternity—and still sticking our heads in the sand‎

The Kunming-Montreal Global Biodiversity Framework states that plastic pollution must be eliminated by 2030. So why haven't we enacted measures that make a real difference?

Wildflower season starts early: Big displays emerge a month before mid-March‎

Though superbloom is not a scientific term, that doesn't stop legions from hoping for a giant display of wildflowers come springtime. UC Riverside plant ecologist Loralee Larios weighs in here on the outlook for such a show this year, where one might see it, and how flower lovers can protect the blooms for years to come.
