Providing a solution to the worst-ever prediction in physics
Providing a solution to the worst-ever prediction in physics
A UNIGE physicist has proposed a new approach to solving one of the biggest theoretical problems in physics: the cosmological constant. The cosmological constant, introduced a century ago by Albert Einstein in his theory of general relativity, is a thorn in the side of physicists. The difference between the theoretical prediction of this parameter and its measurement based on astronomical observations is of the order of 10121.

New biosensor provides insight into the stress behaviour of plants
They are tiny signalling molecules that play important roles in many processes in living organisms. However, the exact function of these substances is often still unknown, which is why scientists are constantly on the lookout for new methods with which they can further investigate them. Researchers at the Universities of Münster and Nanjing (China) have developed such a method for an important messenger substance in plants, called phosphatidic acid.

Universal algorithm set to boost microscopes
Universal algorithm set to boost microscopes
EPFL scientists have developed an algorithm that can determine whether a super-resolution microscope is operating at maximum resolution based on a single image. The method is compatible with all types of microscopes and could one day be a standard feature of automated models. Thanks to the advent of super-resolution microscopes some 30 years ago, scientists can observe subcellular structures, proteins and living tissue with unprecedented precision.

Water droplets spontaneously produce hydrogen peroxide
Water droplets spontaneously produce hydrogen peroxide
Despite its abundance, water retains a great many secrets. Among them, Stanford chemists have discovered, is that water microdroplets spontaneously produce hydrogen peroxide. Water is everywhere on Earth, but maybe that just gives it more space to hide its secrets. Its latest surprise, Stanford researchers report Aug.

Scientists harness bacteria to create ’living’ liquid crystals
Liquid crystals are widely used in technologies such as displays, which manipulate their orientation to display colors across the spectrum. In traditional displays, liquid crystals are stationary and uniform, free of defects. But that stillness can be altered by adding bacteria to the crystals, creating what scientists and engineers call "living liquid crystals": materials that can act autonomously.

Visualising strong magnetic fields with neutrons
Visualising strong magnetic fields with neutrons
Researchers at the Paul Scherrer Institute PSI have developed a new method with which strong magnetic fields can be precisely measured. They use neutrons obtained from the SINQ spallation source. In the future, it will therefore be possible to measure the fields of magnets that are already installed in devices and thus are inaccessible by other probing techniques.

Quantum gravity's tangled time
Quantum gravity’s tangled time
The theories of quantum mechanics and gravity are notorious for being incompatible, despite the efforts of scores of physicists over the past fifty years. However, recently an international team of researchers led by physicists from the University of Vienna, the Austrian Academy of Sciences as well as the University of Queensland (AUS) and the Stevens Institute of Technology (USA) have combined the key elements of the two theories describing the flow of time and discovered that temporal order between events can exhibit genuine quantum features.

New theory explains earthquakes we can’t feel
Researchers have explained mysterious slow-moving earthquakes known as slow slip events with the help of computer simulations. The answer, they learned, is in rocks' pores. The Earth's subsurface is an extremely active place, where the movements and friction of plates deep underground shape our landscape and govern the intensity of hazards above.

Deep learning enables scientists to identify cancer cells in blood in milliseconds
Researchers at UCLA and NantWorks have developed an artificial intelligence-powered device that detects cancer cells in a few milliseconds — hundreds of times faster than previous methods. With that speed, the invention could make it possible to extract cancer cells from blood immediately after they are detected, which could in turn help prevent the disease from spreading in the body.

A hallmark of superconductivity, beyond superconductivity itself
A hallmark of superconductivity, beyond superconductivity itself
'Electron pairing' found well above superconductor's critical temperature Physicists have found "electron pairing,” a hallmark feature of superconductivity, at temperatures and energies well above the critical threshold where superconductivity happens. Rice University's Doug Natelson , co-corresponding author of a paper about the work in this week's Nature, said the discovery of Cooper pairs of electrons "a bit above the critical temperature won't be 'crazy surprising' to some people.

Making biominerals: nature’s recipe is old, evolved more than once
In recent years, scientists have teased out many of the secrets of biomineralization, the process by which sea urchins grow spines, mollusks build their shells and corals make their skeletons, not to mention how mammals and other animals make bones and teeth. The materials that animals make from scratch to build protective shells, razor sharp teeth, load-bearing bones and needlelike spines are some of the hardest and most durable substances known.

Lab-based dark energy experiment narrows search options for elusive force
An experiment to test a popular theory of dark energy has found no evidence of new forces, placing strong constraints on related theories. Dark energy is the name given to an unknown force that is causing the universe to expand at an accelerating rate. It is very exciting to be able to discover something about the evolution of the universe using a table-top experiment in a London basement.

Atomically thin heat shield protects electronics
Atomically thin heat shield protects electronics
Atomically thin materials developed by Stanford researchers could create heat-shields for cell phones or laptops that would protect people and temperature-sensitive components and make future electronic gadgets even more compact. Excess heat given off by smartphones, laptops and other electronic devices can be annoying, but beyond that it contributes to malfunctions and, in extreme cases, can even cause lithium batteries to explode.
