First study with CHEOPS data describes one of the most extreme planets in the universe

CHEOPS keeps its promise: Observations with the space telescope reveal details of the exoplanet WASP-189b – one of the most extreme planets known. CHEOPS is a joint mission by the…

Artificial intelligence can help protect orchids and other species

Orchids are quite decorative. However, many orchid species are also threatened by land conversion and illegal harvesting. But only a fraction of those species is included in the IUCN Red…

Scientists achieve higher precision weak force measurement between protons, neutrons

Through a one-of-a-kind experiment at the Department of Energy’s Oak Ridge National Laboratory, nuclear physicists have precisely measured the weak interaction between protons and neutrons. The result quantifies the weak…

High-performance single-atom catalysts for high-temperature fuel cells

Individual Pt atoms participate in catalytic reaction to faciitate the electrode process by up to 10 times. Single-atom Pt catalysts are stable at 700 degrees Celsius and expected to stimulate…

New method allows precise gene control by light

A novel optical switch makes it possible to precisely control the lifespan of genetic “copies”. These are used by the cell as building instructions for the production of proteins. The…

The groove of the self-organized active nematic ribbon

Soft matter on new ways to self-organization Nematic materials, such as the liquid crystals in our displays, contain molecules that align themselves in parallel. When they are constructed from microtubules…

Nanocrystals make volcanoes explode

Bayreuth geoscientist discovers causes of sudden eruptions Tiny crystals, ten thousand times thinner than a human hair, can cause explosive volcanic eruptions. This surprising connection has recently been discovered by…

Cheering up a frustrated quantum system

One of the holy-grail questions in condensed matter physics is how superconductivity — the property of many electrons to go into a quantum soup state that can carry electricity without…

One bacterium – two life forms

Secondary variant of Photorhabdus luminescens interacts with plant roots New form of insect-pathogenic bacterium extends the options for sustainable crop protection and biological pest control in agriculture. One of the…

Primate brain size does not predict their intelligence

Scientists from Göttingen compare cognitive skills of different primate species. Chimpanzees, gorillas and orangutans are our closest relatives, and like us they have relatively large brains and they are very…

Discovery of large family of two-dimensional ferroelectric metals

It is usually believed that ferroelectricity can appear in insulating or semiconducting materials rather than in metals, because conducting electrons of metals always screen out the internal static electric field…

Understanding ghost particle interactions

Scientists often refer to the neutrino as the “ghost particle.” Neutrinos were one of the most abundant particles at the origin of the universe and remain so today. Fusion reactions in…

First measurements of radiation levels on the moon

In the coming years and decades, various nations want to explore the moon, and plan to send astronauts there again for this purpose. But on our inhospitable satellite, space radiation…

Copycat plant booster improves on nature

A molecule that can mimic the function of zaxinone, a natural growth-promoting plant metabolite, has been designed and fabricated by an international team led by KAUST and the University of…

Recording thousands of nerve cell impulses at high resolution

For over 15 years, ETH Professor Andreas Hierlemann and his group have been developing microelectrode-array chips that can be used to precisely excite nerve cells in cell cultures and to…

Mystery of giant proton pump solved

Mitochondria are the powerhouses of our cells, generating energy that supports life. A giant molecular proton pump, called complex I, is crucial: It sets in motion a chain of reactions,…

Surplus sugar helps whiteflies detoxify plant defenses

This pest insect uses sugar from its food to prevent the activation of the mustard oil bomb in cruciferous plants. Worldwide dreaded crop pest of hundreds of plant species Whiteflies…

Broad beans versus soybeans as feedstuff for dual-purpose chickens

Current practices of the poultry industry have raised ethical and ecological concerns: ethical concerns include the culling of day-old male chicks of egg-laying breeds; ecological concerns include the import of…

Could breadfruit be the next superfood?

UBC researchers say yes Breadfruit is sustainable, environmentally friendly and a high-production crop. A fruit used for centuries in countries around the world is getting the nutritional thumbs-up from a…

New brain cell-like nanodevices work together to identify mutations in viruses

These systems could potentially overcome computational hurdles faced by current digital technologies. In the September issue of the journal Nature, scientists from Texas A&M University, Hewlett Packard Labs and Stanford…

Hyperbolic metamaterials exhibit 2T physics

3D nonlinear ferro-fluid-based hyperbolic metamaterials may contribute to ultra-fast all-optical hyper-computing. Metamaterials–nanoengineered structures designed for precise control and manipulation of electromagnetic waves–have enabled such innovations as invisibility cloaks and super-resolution…
