AEgIS on track to test freefall of antimatter

It's a fundamental law of physics that even the most ardent science-phobe can define: matter falls down under gravity. But what about antimatter, which has the same mass but opposite electrical charge and spin? According to Einstein's general theory of relativity, gravity should treat matter and antimatter identically. Finding even the slightest difference in their free-fall rate would therefore lead to a revolution in our understanding.

More Than 40% of Languages Are at Risk of Fading Away Completely

Thousands of languages are considered endangered. Preservation requires documenting vocabulary and teaching new speakers before it's too late.

Planetary Alignment Didn’t End the World in 1919. But One Professor Thought It Would

Famous for his drastic weather predictions, Albert F. Porta's name could be seen in local papers across the country in the early 1900s. His story is a cautionary tale of how fake news spreads when the world is in disarray.

Placing cosmological constraints on quantum gravity phenomenology

Researchers have used well-established cosmological observations to place tighter constraints on the quadratic model of the Generalized Uncertainty Principle, while discrediting the linear model.

Quantum effects help minimize communication flaws

Noise limits the performance of modern quantum technologies. However, particles traveling in a superposition of paths can bypass noise in communication. New research reveals novel techniques to reduce noise in quantum communication. The results demonstrate that quantum particles traveling in a superposition of paths enable noise reduction in communications.

What Shape Is the Universe?

As far as cosmologists can tell, space is almost perfectly flat. But what does this mean?

Scientists develop new, faster method for seeking out dark matter

For nearly a century, scientists have worked to unravel the mystery of dark matter—an elusive substance that spreads through the universe and likely makes up much of its mass, but has so far proven impossible to detect in experiments. Now, a team of researchers have used an innovative technique called "quantum squeezing" to dramatically speed up the search for one candidate for dark matter in the lab.

Jezero Crater: A Closer Look at the Perseverance Rover's Landing Site

Jezero Crater once could have been a prime location for martian microbial mats. And Perseverance aims to find out if any Martian fossils were left behind.

Really random networks

Many natural and human-made networks, such as computer, biological or social networks have a connectivity structure that critically shapes their behavior. The academic field of network science is concerned with analyzing such real-world complex networks and understanding how their structure influences their function or behavior. Examples are the vascular network of our bodies, the network of neurons in our brain, or the network of how an epidemic is spreading through a society.

Astronauts Get Sick, Too. Here's the Tech That Could Grow Medicine on Mars

Shipping drugs to the Red Planet would be costly and impractical. But what if the astronauts could grow their own pharmacy once they got there?
