Mining genomes for cyst nematode resistance could enable better soybean harvests‎

Soybean farmers around the world face a persistent and costly enemy hidden beneath the soil: soybean cyst nematode (SCN), a microscopic roundworm that attacks plant roots and drains yields. SCN is one of the most damaging pests affecting soybean production globally, resulting in significant losses every year.

Edison's 1879 bulb experiments may have unintentionally produced graphene‎

What do Thomas Edison and 2010 Nobel Prize in physics winners Konstantin Novoselov and Andre Geim have in common? According to a recent publication from the lab of Rice University's James Tour in ACS Nano, it could be graphene—an answer that might have confused Edison, who died almost 20 years before physicist P.R. Wallace proposed such a substance could exist and nearly 80 years before Novoselov and Geim were awarded a Nobel Prize for isolating and characterizing it.

Why do onions and chips keep washing up on England's south coast? Here's the science‎

Over Christmas, vegetables, bananas and insulation foam washed up on beaches along England's southeast coast. They were from 16 containers spilled by the cargo ship Baltic Klipper in rough seas. In the new year, a further 24 containers fell from two vessels during Storm Goretti, with chips and onions among the goods appearing on the Sussex shoreline.

General ad campaign for climate action receives more public engagement than tailored approach, study finds‎

Researchers investigating the effectiveness of outdoor ads promoting climate change awareness and action found that a general message of climate emergency awareness received more QR code scans compared to a more-specific campaign focusing on sustainable fashion, according to a study published in PLOS Climate by Maxwell Boykoff from the University of Colorado Boulder, U.S., and colleagues.

Why some messages are more convincing than others‎

What kinds of marketing messages are effective—and what makes people believe certain political slogans more than others? New research from the University of California San Diego Rady School of Management explores how people constantly evaluate whether messages are true or false and finds that a surprisingly small ingredient—whether a word has an easy opposite—can shape how confident people feel when deciding whether a message is true.

New nanoparticle technology offers hope for hard-to-treat diseases‎

A newly published Perspective article in Nature Nanotechnology details groundbreaking nanoparticle technology to eliminate harmful, disease-causing proteins in the body. The technology marks a transformative leap in the potential to drug "undruggable" proteins, to treat diseases such as dementia and brain cancer.

New study sheds light on the threat of 'marine darkwaves' to ocean life‎

Life in the ocean runs on light. It fuels photosynthesis, shapes food webs and determines where many marine species can live.

Microplastics in the atmosphere: Higher emissions come from land areas than from the ocean, study finds‎

The atmosphere is an important transport medium that carries microplastics to even the most remote parts of the world. These microplastics can be inhaled and pose a health risk to humans and animals. They can also settle out of the atmosphere and contaminate oceans and soils worldwide.

An app that uses drone footage to track plastic litter on beaches is promoting voluntary cleanup in Ireland‎

Plastic pollution is one of those problems everyone can see, yet few know how to tackle it effectively. I grew up walking the beaches around Tramore in County Waterford, Ireland, where plastic debris has always been part of the coastline, including bottles, fragments of fishing gear and food packaging.
