Researchers have uncovered the first direct evidence that the West Antarctic Ice Sheet shrunk suddenly and dramatically at the end of the Last Ice Age, around eight thousand years ago. The evidence, contained within an ice core, shows that in one location the ice sheet thinned by 450 meters -- that's more than the height of the Empire State Building -- in just under 200 years.

In a study that signals potential reproductive and health complications in humans, now and for future generations, researchers have concluded that fathers exposed to environmental toxins, notably DDT, may produce sperm with health consequences for their children.

The same phosphorus that fertilizes the thriving agriculture of the Midwest is also responsible for a vast 'dead zone' in the Gulf of Mexico near the Mississippi Delta. Efforts to reduce the amount of phosphorus that enters the Mississippi River system are underway, but research suggests that remnants of the contaminant are left behind in riverbeds for years after introduction and pose an overlooked -- and lingering -- problem.

Researchers report that replacing 50% of animal products with alternative proteins by 2050 could free up enough agricultural land to generate renewable energy equivalent in volume to today's coal-generated power while simultaneously removing substantial CO2 from the atmosphere.

Researchers say there needs to be better regulation and more guidance for consumers about how safe cleaning products really are.

Over the past 15 years, researchers have identified hundreds of regions in the human genome associated with heart attack risk. However, researchers lack efficient ways to explore how these genetic variants are molecularly connected to cardiovascular disease, limiting efforts to develop therapeutics. To streamline analysis of hundreds of genetic variants associated with coronary artery disease (CAD), a team of researchers combined multiple sequencing and experimental techniques to map the relationship between known CAD variants and the biological pathways they impact.

Despite efforts to mitigate the effects of climate change, companies are not set up for success, due to conflicting national and sectorial targets and differing availability of abatement options, a new study reveals.

Forests, which cover a third of Earth's land surface, are pivotal in carbon storage and the water cycle, though the full scope of their impact remains to be fully understood. In a new study, researchers provide new insights into the complex role forests play in the climate system and water cycle.

When it comes to making fuel from plants, the first step has always been the hardest -- breaking down the plant matter. A new study finds that introducing a simple, renewable chemical to the pretreatment step can finally make next-generation biofuel production both cost-effective and carbon neutral.

For the first time, a hydrogel material made of nanocellulose and algae has been tested as an alternative, greener architectural material. The study shows how the abundant sustainable material can be 3D printed into a wide array of architectural components, using much less energy than conventional construction methods.

One of the most important components of satellites that enable telecommunication is the waveguide, which is a metal tube for guiding radio waves. It is also one of the heaviest payloads satellites carry into orbit. As with all space technology, reducing weight means reducing the amount of expensive and greenhouse gas-producing fuel it takes to launch a rocket, or increasing the number of devices carried by the same rocket to space. Researchers are trying to lighten the load by creating and testing a waveguide made from 3D-printed polymers coated with a conductive nanomaterial called MXene.

Researchers report that Japan's policy of banning the sale of new gas vehicles by 2035 may be insufficient to reduce the country's CO2 emissions. The team's analysis showed that to effectively reach their climate goals, Japan must also implement policies that extend vehicle lifetime, implement more renewable energy into its energy sector, and decarbonize the manufacturing process of vehicles.

Researchers have identified a 'sweet spot' at which the length of a threadlike energy storage technology called a 'yarn-shaped supercapacitor' (YSC) yields the highest and most efficient flow of energy per unit length.
