According to quantum mechanics, the physics theory that describes the zoo of subatomic particles, all matter can be described as both particles and waves. But is it real?
Researchers have finally succeeded in building a long-sought nanoparticle structure, opening the door to new materials with special properties.
Alex Travesset does not have a sparkling research lab stocked with the most cutting-edge instruments for probing new nanomaterials and measuring their unique properties.
Instead of using traditional laboratory instruments, Alex Travesset, a professor of physics and astronomy at Iowa State University and an affiliate of the U.S. Department of Energy’s Ames National Laboratory, relies on computer models, equations, and figures to understand the behavior of new nanomaterials.

Lupin Pharmaceuticals issued a voluntary recall of some blood pressure medication due to the potential presence of a nitrosamine impurity, according to a notice published on the Food and Drug Administration’s (FDA) website.
The recall, issued last week, includes one batch of 20-milligram Quinapril Tablets USP — G102929 — and three batches of 40-milligram Quinapril Tablets USP – G100533, G100534 and G203071, the notice said.
Consumers, wholesalers, distributors and retailers can find the lot number on the side of the label affixed to bottles.

“This launch marks the first of Starlink’s upgraded network. Under our new license, we [can now] deploy satellites to new orbits that will add even more capacity to the network,” SpaceX explained in its mission description.
A team led by UCL and UCLH researchers have mapped the parts of the brain that support our ability to solve problems without prior experience—otherwise known as fluid intelligence.
Fluid intelligence is arguably the defining feature of human cognition. It predicts educational and professional success, social mobility, health, and longevity. It also correlates with many cognitive abilities such as memory.
Fluid intelligence is thought to be a key feature involved in “active thinking”—a set of complex mental processes such as those involved in abstraction, judgment, attention, strategy generation and inhibition. These skills can all be used in everyday activities—from organizing a dinner party to filling out a tax return.
SpaceX launched the first batch of a new generation of Starlink satellites into orbit early Wednesday (Dec. 28) and nailed a rocket landing at sea to mark a record 60th flight of the year.
A Falcon 9 rocket topped with 54 upgraded Starlink internet satellites — the first generation 2 (Gen2) versions of the SpaceX fleet — lit up the predawn sky with a smooth launch at 4:34 a.m. EST (0934 GMT) from the Cape Canaveral Space Force Station in Florida.
When a German security researcher, Matthias Marx, found a United States military device for sale on eBay—an instrument previously used to identify wanted individuals and known terrorists during the War in Afghanistan—Marx gambled a little and placed a low bid of $68.
He probably didn’t expect to win, since he offered less than half the seller’s asking price, $149.95. But win he did, and after that, he had an even bigger surprise coming, The New York Times reported. When the device arrived with a memory card still inside, Marx was shocked to realize he had unwittingly purchased the names, nationalities, photographs, fingerprints, and iris scans of 2,632 people whose biometric data had allegedly been scanned by US military.
The device allegedly stored not just personal identifiable information (PII) of seemingly suspicious persons, but also of US military members, people in Afghanistan who worked with the government, and ordinary people temporarily detained at military checkpoints. Most of the data came from residents of Afghanistan and Iraq.
A research team led by Prof. Li Di from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) has revealed circular polarization in active repeating fast radio bursts based on precise observations of the Five-hundred-meter Aperture Spherical Telescope (FAST).
Their findings were published in Science Bulletin.
Fast radio bursts (FRBs) are the most luminous radio flashes in the universe. The estimated equivalent energy of one FRB event can rival the energy output the sun over a whole day or even a month to a year.
While significant parts of the globe are already facing significant freshwater scarcity, the need for more freshwater is projected to increase in order to sustain the increasing global population and economic growth and adapt to climate change.
An almost limitless supply of fresh water exists in the form of water vapor above Earth’s oceans, yet remains untapped. Now, researchers at the University of Illinois Urbana-Champaign (UIUC) have proposed a new infrastructure capable of harvesting oceanic water vapor as a solution to limited supplies of fresh water in various locations around the world.
The study evaluated 14 water-stressed locations across the globe for the feasibility of a hypothetical structure capable of capturing water vapor from above the ocean and condensing it into fresh water – and doing so in a manner that will remain feasible in the face of continued climate change.
