Feeling secure in a group may help dissenters make stronger arguments‎

When everyone in a meeting voices the same opinion, an organization can miss important warning signs and new ideas. A research team from KAIST suggests that when members feel securely accepted within their group, they can express dissenting opinions in greater detail and more persuasively, and other members may be more willing to use those opinions in decision-making.

How can the same El Niño cause drought in one part of the world and floods in another?‎

The Pacific Ocean is warming unusually quickly, and this year's El Niño has already surpassed previous records. Forecasters expect it to strengthen even further before approaching its usual peak around December.

Today's emissions choices could limit Antarctic ice loss and sea-level rise for coastal communities‎

Cutting greenhouse gas emissions now may limit how much ice Antarctica loses this century and reduce the sea-level rise facing coastal communities, according to findings from a new study.

New reactor design improves plastic feedstock synthesis using oxygen and electricity‎

A "hidden variable" that can determine the success or failure of a chemical reaction has been found in the immediate vicinity of electrodes.

Recovery after intimate partner violence: New study reveals what works‎

Violence in the home can range from intimidation to physical abuse. When it occurs there, we refer to it as domestic violence. Every year, more than 1 million people in the Netherlands age 16 and older experience domestic violence. This type of violence is often perpetrated by a current or former partner, in which case it is referred to as intimate partner violence.

Reading hidden topology in light, even when energy leaks away‎

When I explain topology to students, I start with a knot in a rope. You can stretch it, twist it or shake it, but the knot stays until you cut the rope. Physicists have found that some materials and devices carry similar "knots" in how waves move through them. These are topological properties, labeled by whole numbers that don't change under small imperfections. That robustness is why topology has become one of the central ideas in modern physics. It promises electronics, photonics and quantum devices that tolerate defects and noise.

Q&A: An Earth-like planet with two suns?‎

A nearby star system with two suns could potentially support an Earth-sized planet in a region where liquid water could exist, according to a new paper examining the dynamics of the system.

Visible light does not speed up water evaporation, rigorous experiments suggest‎

In recent experiments involving hydrogels and water droplets, researchers have proposed that exposure to visible light could make water evaporate faster without heating it. However, direct evidence that light acts on water itself has proven elusive.

When the atmosphere slows the Earth: Uncovering a subtle signal of climate change‎

Atmospheric circulation governs weather and climate, but it also carries angular momentum. When winds shift or mass redistributes, the atmosphere can exchange momentum with the solid Earth, slightly altering the planet's rotation rate. This is not a new concept, but what happens under long-term global warming?

New imaging technologies offer a clearer view of coral reef change‎

From a drone flying above the waves to a camera just inches from the seafloor, University of Miami researchers are transforming how scientists observe coral reefs and measure changes that were once difficult, costly or time-consuming to document.
