Non-Hermitian geometry reveals when quantum amplification depends only on start and end po

In quantum mechanics, the geometry of quantum states has emerged as a powerful framework for understanding phenomena ranging from electrical conductivity to superconductivity. One research direction aims to extend these geometric concepts to non-Hermitian quantum mechanics—where

Coastal and estuarine carbon removal technique may backfire when pushed too far

Scientists investigating a proposed way to remove carbon dioxide from the atmosphere using seawater have found that adding too much alkalinity to neutralize acids can trigger chemical reactions that undermine the process.

When the rapid adaptation of sales channels pays off

Greater agility in the sales system—that is, a company's ability to rapidly adapt its sales channels to changing market conditions—is associated with higher operating profit, but only under certain conditions. That is the result of an observational, survey-based study involving 3

Brain activity under anesthesia challenges what we know about consciousness

The unconscious brain appears to be far more capable than scientists once believed. Researchers found that patients under general anesthesia could still process language at a sophisticated level, distinguishing nouns, verbs, and adjectives while listening to stories. Even more re

Nanopore technology identifies proteins molecule by molecule

Proteins are responsible for most functions in the human body. However, their analysis, which is essential for understanding diseases, developing drugs and discovering new biomarkers, remains highly complex. Using a technology called "nanopore detection," a team at the University

DNA databases unite to create a fully open resource for transposable element research

For more than three decades, researchers studying genomes have relied on foundational resources such as Repbase and, more recently, Dfam to identify and classify transposable elements—the mobile DNA sequences that shape genome structure, evolution and function. Now, Dfam and Repb

Giraffes combine quantities similarly to addition

In addition to humans, some species of primates and birds have demonstrated under experimental conditions their ability to manipulate quantities in tasks that require combining or separating them, in a manner similar to addition or subtraction. Now, a study by the University of B

Decline in plankton across Northeast Atlantic sends stark warning for ocean health

Microscopic plankton are among the most important organisms on Earth. Phytoplankton produce around half of the oxygen we breathe, while plankton as a whole underpin marine food webs, support fisheries, help regulate carbon and sustain life across the ocean.

Unintended climate trade-off: Clean air policies intensify urban heat island in humid citi

Researchers at the University of Hong Kong (HKU) have uncovered a critical, underrecognized trade-off in global environmental policies: While essential for improving public health, large-scale air pollution reductions are unintentionally intensifying warm-season surface urban hea

Heat is destroying Australia's underwater forests. Seaweed biobanks could help save them

Australia's Great Southern Reef is built not by coral but by seaweed. The seaweed forests on these rocky reefs stretch more than 8,000 kilometers (5,000 miles) around southern Australia.

Nova V612 Scuti's light curve becomes audio, revealing how stellar shocks evolved

Researchers in the Department of Physics & Astronomy at Texas Tech University recently used audio to represent the spectacular explosion of a star in deep space while also delving into the data to better understand how the phenomenon unfolded.
