Detective work in theoretical physics
Detective work in theoretical physics
Scientific articles in the field of physics are mostly very short and deal with a very restricted topic. A remarkable exception to this is an article published recently by physicists from the Universities of Münster and Düsseldorf. The article is 127 pages long, cites a total of 1075 sources and deals with a wide range of branches of physics - from biophysics to quantum mechanics.

Fermilab and partners achieve sustained, high-fidelity quantum teleportation
A viable quantum internet-a network in which information stored in qubits is shared over long distances through entanglement-would transform the fields of data storage, precision sensing and computing, ushering in a new era of communication. This month, scientists at Fermi National Accelerator Laboratory-a U.S. Department of Energy national laboratory affiliated with the University of Chicago-along with partners at five institutions took a significant step in the direction of realizing a quantum internet.

Ripples in space-time could provide clues to missing components of the universe
UChicago scientist lays out how LIGO gravitational waves could be scrambled, yielding information There's something a little off about our theory of the universe. Almost everything fits, but there's a fly in the cosmic ointment, a particle of sand in the infinite sandwich. Some scientists think the culprit might be gravity-and that subtle ripples in the fabric of space-time could help us find the missing piece.

Berkeley Lab's Top 10 Science Stories of 2020
Berkeley Lab’s Top 10 Science Stories of 2020
It was a year dominated by COVID-19 research, along with some beetles, batteries, and a Nobel Prize T he coronavirus pandemic has taught us many valuable lessons this year, and perhaps foremost among them is the importance of science. Researchers at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have always strived to find science-based solutions for society's most pressing issues.

How Nearby Galaxies Form Their Stars
How Nearby Galaxies Form Their Stars
How stars form in galaxies remains a major open question in astrophysics. A new UZH study sheds new light on this topic with the help of a data-driven re-analysis of observational measurements. The star-formation activity of typical, nearby galaxies is found to scale proportionally with the amount of gas present in these galaxies.

The Mechanics of the Immune System
The Mechanics of the Immune System
When T-cells of our immune system become active, tiny traction forces at the molecular level play an important role. They have now been studied at TU Wien. Highly complicated processes constantly take place in our body to keep pathogens in check: The T-cells of our immune system are busy searching for antigens - suspicious molecules that fit exactly into certain receptors of the T-cells like a key into a lock.

When light and atoms share a common vibe
Scientists from EPFL, MIT, and CEA Saclay demonstrate a state of vibration that exists simultaneously at two different times. They evidence this quantum superposition by measuring the strongest class of quantum correlations between light beams that interact with the vibration. An especially counter-intuitive feature of quantum mechanics is that a single event can exist in a state of superposition - happening bothhere andthere , or bothtoday andtomorrow .

On the hunt for a missing giant black hole
On the hunt for a missing giant black hole
The mystery surrounding the whereabouts of a supermassive black hole has deepened. Despite searching with NASA's Chandra X-ray Observatory and Hubble Space Telescope, astronomers have no evidence that a distant black hole estimated to weigh between 3 billion and 100 billion times the mass of the sun is anywhere to be found.

Pseudospin in antiferromagnets: new perspectives for information technologies Elementary particles carry an intrinsic angular momentum known as their spin. For an electron, the spin can take only two particular values relative to a quantization axis, letting us denote them as spin-up and spin-down electrons.

Big step with small whirls
Big step with small whirls
Skyrmions are small magnetic objects that could revolutionize the data storage industry and also enable new computer architectures. However, before they can be utilized in such applications, there are still a number of challenges that need to be overcome. A team of Empa researchers has now succeeded for the first time in producing a tunable multilayer system in which two different types of skyrmions - the future bits for "0" and "1" - can exist at room temperature, as they recently reported in the renowned .

How heavy is Dark Matter? Scientists radically narrow the potential mass range for the first time
Scientists have calculated the mass range for Dark Matter - and it's tighter than the science world thought. Their findings - due to be published in Physical Letters B in March - radically narrow the range of potential masses for Dark Matter particles, and help to focus the search for future Dark Matter-hunters.

Weak force has strong impact on nanosheets
Rice lab finds van der Waals force can deform nanoscale silver for optics, catalytic use You have to look closely, but the hills are alive with the force of van der Waals. Rice University scientists found that nature's ubiquitous "weak" force is sufficient to indent rigid nanosheets, extending their potential for use in nanoscale optics or catalytic systems.
