Formation-flying spacecraft could probe the solar system for new physics
It's an exciting time for the fields of astronomy, astrophysics, and cosmology. Thanks to cutting-edge observatories, instruments, and new techniques, scientists are getting closer to experimentally verifying theories that remain largely untested. Th.....»»
Hyundai dealership customer sues CDK over cyberattacks
A Hyundai dealership lease customer on July 22 joined other consumers who have sued CDK Global, alleging their data was put at risk by the June 19 cyberattacks suffered by the dealership management system provider. Ronaldo Proto of Connecticut filed.....»»
Is this how you get hot Jupiters?
When we think of Jupiter-type planets, we usually picture massive cloud-covered worlds orbiting far from their stars. That distance keeps their volatile gases from vaporizing from stellar heat, similar to what we're familiar with in our solar system......»»

New nanoparticles boost immune system in mice to fight melanoma and breast cancer
Vanderbilt researchers have developed a set of nanoparticles that stimulate the immune system in mice to fight cancer and may eventually do the same in humans......»»
Kepler"s 1607 pioneering sunspot sketches solve solar mysteries 400 years later
Using modern techniques, researchers have re-examined Johannes Kepler's half-forgotten sunspot drawings and revealed previously-hidden information about the solar cycles before the grand solar minimum......»»
ATLAS probes uncharted territory with LHC Run 3 data
Despite its immense success in describing the fundamental building blocks of matter and their interactions, the Standard Model of particle physics is known to be incomplete. Experiments around the globe and in space are therefore searching for signs.....»»
No, You Can’t Have a Solar-Powered Passenger Plane
Guilt-free air travel is a beautiful dream, but there’s simply no way to get enough solar energy to keep a cabin full of people in the air......»»
Ice 0: Researchers discover a new mechanism for ice formation
Ice is far more complicated than most of us realize, with over 20 different varieties known to science, forming under various combinations of pressure and temperature. The kind we use to chill our drinks is known as ice I, and it's one of the few for.....»»
Warming has more impact than cooling on Greenland"s "firn," physics-based model reveals
Scientists have known from ice core research that it's easier to melt an ice sheet than to freeze it up again. Now, they know at least part of the reason why, and it has to do with ice's "sponginess," according to a new study published July 24 in The.....»»
US solar production soars by 25 percent in just one year
2024 is seeing the inevitable outcome of the building boom in solar farms. Enlarge (credit: Vithun Khamsong) With the plunging price of photovoltaics, the construction of solar plants has boomed in the US. Last year, for.....»»

How Soon Might the Atlantic Ocean Break? Two Sibling Scientists Found an Answer—and Shook the World
A gigantic, weather-defining current system could be headed to collapse. Peter and Susanne Ditlevsen had a simple yet controversial question: How much time might we have left to save it?.....»»
Confined water gets electric: Study reveals dielectric response of water in nanopores
When water gets inside nanopores with sizes below 10 nanometers, new physics emerge: new phases of ice were observed and ultrafast proton transport was measured. Confined water also plays a role in biology, where aquaporins cross cellular membranes t.....»»
