For couples, one affectionate communicator can help both partners feel relationship satisfaction‎

If you really like holding hands and saying "I love you" but your partner doesn't, your relationship is still probably better off than if both of you had a modest interest in expressing affection.

New tool will help manage one of Nevada's most critical freshwater sources‎

The Nature Conservancy in Nevada (TNC in Nevada), DRI, and the University of Wisconsin—Madison (UW-Madison) have developed the Nevada GDE Water Needs Explorer Tool. This new online resource helps land and water managers understand how groundwater supports groundwater-dependent ecosystems (GDEs) and how changes in water levels can affect them.

Global health impacts of plastics systems set to double by 2040‎

The adverse health impacts associated with emissions across the full life cycle of plastics could double by 2040 unless immediate action is taken, new research suggests. The study identified health harms at every stage of the life cycle of the plastics we use: from the extraction of fossil fuels, the feedstocks for more than 90% of plastics, and material production to their eventual disposal or release to the environment.

Footprint tracker identifies tiny mammals with up to 96% accuracy‎

It might be less visible than dwindling lion populations or vanishing pandas, but the quiet crisis of small mammal extinction is arguably worse for biodiversity. These species are crucial indicators of environmental health, but they can be very hard to monitor, and many species with very different ecological niches look almost identical.

How political leanings affect views on academic freedom: New research‎

Academic freedom is often described as a cornerstone of democratic society. Politicians regularly claim to defend it, universities invoke it in mission statements and most members of the public say they support it in principle.

A brief history of sugar‎

A few thousand years ago, sugar was unknown in the western world. Sugarcane, a tall grass first domesticated in New Guinea around 6000BC, was initially chewed for its sweet juice rather than crystallized. By around 500BC, methods to boil sugarcane juice into crystals were first developed in India.

Q&A: Uncovering the low-temperature oxygen storage and release mechanism of Mn–CeO₂ nanoparticles‎

The search for better oxygen carriers has long centered on one key question: how can we design metal oxides that can reversibly store and release lattice oxygen efficiently at lower temperatures? This reversible behavior underpins clean-energy technologies such as fuel conversion, CO2 capture, and chemical looping for hydrogen production, where reaction feasibility and efficiency depend directly on a material's oxygen storage and release capacity (OSC).

Unlocking defect-free graphene electrodes for transparent electronics‎

Transparent electrodes transmit light while conducting electricity and are increasingly important in bioelectronic and optoelectronic devices. Their combination of high optical transparency, low electrical resistance, and mechanical flexibility makes them well suited for applications such as displays, solar cells, and wearable or implantable technologies.

Radical transparency is required to scale carbon dioxide removal, expert says‎

Last week, Yale Center for Natural Carbon Capture (YCNCC) Scientific Leadership Team member and Earth & Planetary Sciences Professor Noah Planavsky co-authored a peer-reviewed comment in npj Climate Action titled "The importance of radical transparency for responsible carbon dioxide removal." YCNCC News spoke with Planavsky about why greater transparency is necessary, and how transparency is an important theme across the Center's work to advance carbon dioxide removal (CDR).

What is the universe made of? Experts weigh in on the mysterious force that shapes our cosmic history‎

As the Dark Energy Survey (DES) releases its final results, we caught up with two physicists who've been involved in the project from its early days. In this Q&A, Josh Frieman, DES co-founder and associate laboratory director for fundamental physics at the Department of Energy's SLAC National Accelerator Laboratory, and Risa Wechsler, director of the Kavli Institute for Particle Astrophysics and Cosmology, discuss what the decade-long effort taught us and how it prepares us for the NSF–DOE Vera C. Rubin Observatory's 10-year mission to explore some of the universe's biggest mysteries.
