Exposing secret night operations between hawkmoths and Japan's black-nectar flowers‎

Researchers Soma Chiyoda, Ko Mochizuki, and Atsushi Kawakita from the University of Tokyo have discovered that nocturnal hawkmoths are the main pollinators of Jasminanthes mucronata, a plant species native to Japan that produces black nectar. This is the first time that a colored nectar flower has been confirmed to be mainly pollinated by nocturnal insects. The discovery thus promotes further research into this so far unexplored ecology. The findings were published in the journal Ecology.

Can unpaved roads and watersheds co-exist? Researchers wade into the question‎

Imagine a dump truck dropping 13 tons of dirt into the waters of Brush Creek, a waterway that feeds northwest Arkansas' primary drinking water source, Beaver Lake. That's how much soil and sediment researchers measured going into the stream as runoff due to a single large storm event.

A tiny detector for microwave photons could advance quantum tech‎

Detecting a single particle of light is hard; detecting a single microwave photon is even harder. Microwave photons, the tiny packets of electromagnetic radiation used in current technologies like Wi-Fi and radar, carry far less energy than visible light. They are about 100,000 times weaker than optical photons.

High-throughput platform helps engineer fast-acting covalent protein drugs‎

A team led by principal investigators Bobo Dang and Ting Zhou at Westlake University/Westlake Laboratory have developed a high-throughput platform for engineering fast-acting covalent protein therapeutics. Their study, titled "A high-throughput selection system for fast-acting covalent protein drugs" published in Science, opens new avenues for next-generation biologics.

Assembling more than 1,000 human genomes affordably: New method could power genetic screening's future‎

A research team led by Zhen-Xing Endowed Professor Jian Yang at the School of Life Sciences, Westlake University, has developed a pangenome-informed genome assembly (PIGA) method. By combining a cost-effective hybrid sequencing strategy of long and short reads, the team successfully constructed a pangenome for more than 1,000 individuals. This achievement breaks through the limitations of previous small-sample pangenomes and provides a critical foundational infrastructure for medical and population genetics research. The study is published in the journal Nature.

Study examines diversity of Black perspectives on race relations‎

A new Rice University study offers one of the first national measures of a viewpoint called "racial realism" and considers how it fits into the broader spectrum of perspectives Black Americans hold about race relations.

The depths of Neptune and Uranus may be 'superionic'‎

The interiors of ice giant planets like Uranus and Neptune could be home to a previously unknown state of matter, according to new computational simulations by Carnegie's Cong Liu and Ronald Cohen. Their work, published in Nature Communications, predicts that a quasi-one-dimensional superionic state of carbon hydride exists under the extreme pressures and temperatures found deep inside these outer solar system bodies.

Engineering the bite of ancient marine predators‎

An international team of researchers, led by paleontologists of the University of Liège, has investigated the biting capabilities of extinct predatory marine reptiles, revealing how these formidable predators could coexist within the same ecosystem. This work sheds new light on the hunting strategies of long-extinct predators that dominated the seas during the Age of Dinosaurs. The research is published in the journal Palaeontology.

The Habitable Worlds Observatory will need astrometry to find life‎

We're getting closer and closer to finding a real Earth-like exoplanet. But finding one is only half the battle. To truly know if we're looking at an Earth analog somewhere else in the galaxy, we have to directly image it too. That's a job for the Habitable Worlds Observatory (HWO), a planned space-based telescope whose primary job is to do precisely that. But even capturing a picture and a planet and getting spectral readings of its atmospheric chemistry still isn't enough, according to a new paper available on the arXiv preprint server by Kaz Gary of Ohio State and their co-authors. HWO will need to figure out how much a planet weighs first.

3D root model captures mangroves' capacity to protect coastal communities from storm waves‎

Mangrove forests are natural wonders that protect coastal areas, particularly in tropical and subtropical regions. They are able to dissipate wave energy and limit flooding, which can even mitigate tsunamis and coastal inundations during tropical cyclones. For this reason, mangroves are attracting attention as Nature-based Solutions, or NbS: natural infrastructure with the potential to enhance coastal resilience in an environmentally friendly way.
