In this artistic representation, the quantum entanglement of two mechanical resonators is represented by the twisting of two tuning forks, so that they cannot be separated from one another. The fully separated shadows, showing no sign of entanglement, represent the information usually available to physicists during experiments. (Jack Bertram/NIST)
In this artistic representation, the quantum entanglement of two mechanical resonators is represented by the twisting of two tuning forks, so that they cannot be separated from one another. The fully separated shadows, showing no sign of entanglement, represent the information usually available to physicists during experiments. (Jack Bertram/NIST)Two groups of researchers have independently quantum-entangled tiny drum-like structures — a feat difficult to achieve on objects larger than subatomic particles — and performed unprecedented measurements. One group also sidestepped a fundamental quantum limit on measurement uncertainty.

A blood test for cancer DNA? The new test might revolutionize cancer detection. (AP Photo/Jerome Delay)An experimental test successfully detected cancerous mutations in tumor cells by analyzing their DNA that is free-floating in blood, employing a strip test that displays results within 10 minutes.

The bonobo Muhdeblu, pictured here with her newly born offspring in 2014, had her DNA sequenced in a recent genome study. (Claudia Philipp/Wuppertal Zoo)A large collaboration of scientists has sequenced and identified more than 98% of the genes in a bonobo, one of humans' closest evolutionary cousins, revealing surprising speed and complexity in the evolution of genes within the great-ape family and marking a significant improvement from earlier sequencing.

Making cement more efficiently could lead to reductions in greenhouse gases, and using fewer of these familiar vehicles is part of the plan. (Pixabay/Oknesanofa)
Making cement more efficiently could lead to reductions in greenhouse gases, and using fewer of these familiar vehicles is part of the plan. (Pixabay/Oknesanofa)With more energy-efficient methods for production and use, Brazil's cement industry can more than halve its carbon dioxide emissions in the next 30 years while saving nearly $700 million, according to a new analysis — and the reductions could be much deeper, when accounting for cement products' absorption of carbon dioxide from the air.

An image of the atmosphere from the International Space Station. The colors roughly align with different layers of the atmosphere — the orange troposphere, the white stratosphere and the blue mesosphere. (Chris Hadfield)
An image of the atmosphere from the International Space Station. The colors roughly align with different layers of the atmosphere — the orange troposphere, the white stratosphere and the blue mesosphere. (Chris Hadfield)Rising concentrations of carbon dioxide and other greenhouse gases are cooling and shrinking the stratosphere and mesosphere, a phenomenon observed for the first time in a new analysis of satellite data.

Mayall II, also known as Andromeda's Cluster, is a globular cluster located on the outskirts of the Andromeda Galaxy and is believed by some to be the remnants of a cannibalized dwarf galaxy.

(Michael Rich, Kenneth Mighell, and James D. Neill (Columbia University), and Wendy Freedman (Carnegie Observatories), and NASA)Newly discovered stars, tugged away from the Andromeda Galaxy's largest globular cluster by tidal forces, lend credence to the theory that the cluster was once a dwarf galaxy that is being digested by its much larger neighbor.

Pollution in Venice's famous canals dropped sharply during the pandemic. (AP Photo/Antonio Calanni)Less than two months after tourist crowds dispersed during COVID-19 restrictions, the world-famous lagoon of Venice, Italy experienced a 40% decrease in the number of identifiable pollutants known as volatile organic compounds, which are primarily derived from plastics, water traffic and tourism activity.

Cold ocean waters do most of the job of heat absorption in the Earth's ocean system. (Devin Powell/NOAA via AP)
Cold ocean waters do most of the job of heat absorption in the Earth's ocean system. (Devin Powell/NOAA via AP)As the world's oceans bear most of the warming burden created by climate change, a study found that half of all added heat from the last 44 years entered through the coldest one-quarter of surfaces, according to a newly debuted framework that sorts oceanic regions by temperature.

A colorized lattice of tornado-like vortices within a spinning Bose-Einstein condensate of rubidium atoms, imaged by the National Institute of Standards and Technology in 2007. (NIST)For the first time, molecules have been put in an extreme quantum state of matter known as a Bose-Einstein condensate, an experimental result that sets the stage for applications such as new kinds of chemistry and quantum computing.

An experimental hall in the Thomas Jefferson National Accelerator Facility, where a recent experiment revealed new information about the properties of neutrons. (DOE's Jefferson Lab)After 20 years of research plans and experiments, an expansive collaboration of physicists has directly measured the thickness of the layer of neutrons in a lead atom's nucleus, an unprecedented direct observation that informs how atomic nuclei and neutron stars alike remain stable.

New modeling of the way aerosols behave in the atmosphere could help climate prediction. (AP Photo/Chris Pizzello)
New modeling of the way aerosols behave in the atmosphere could help climate prediction. (AP Photo/Chris Pizzello)Three major types of aerosols form up to three different liquid phases simultaneously when they mix in the atmosphere, a once-poorly understood interaction that can better inform future modeling of air pollution and the climate, according to recent research.

Northern Arizona University professor Ted Schuur stands near an eddy covariance tower in a tundra landscape near Denali National Park, Alaska, where his research team studied the carbon flow of permafrost. (Thomas Nash)A 15-year study of Alaskan tundra has demonstrated that thawing permafrost is persistently releasing more carbon-based compounds than it absorbs, a historic reversal that is adding greenhouse gases to the atmosphere and exacerbating the planet's rising temperatures.
