Nanodevices can produce energy from evaporating tap or seawater

Nanodevices can produce energy from evaporating tap or seawater

Evaporation is a natural process so ubiquitous that most of us take it for granted. In fact‚ roughly half of the solar energy that reaches the Earth drives evaporative processes. Since 2017‚ researchers have been working to harness the energy potential of evaporation via the hydrovoltaic (HV) effect‚ which allows electricity to be harvested when fluid is passed over the charged surface of a nanoscale device.

Researchers develop first heat map for individual red blood cells

Researchers develop first heat map for individual red blood cells

Entropy is often associated with disorder and chaos‚ but in biology it is related to energy efficiency and is closely linked to metabolism‚ the set of chemical reactions that sustain life.

$Weird electron behavior gets even weirder: Charge fractionalization observed spectroscopically$

Weird electron behavior gets even weirder: Charge fractionalization observed spectroscopically

A research team led by the Paul Scherrer Institute has spectroscopically observed the fractionalization of electronic charge in an iron-based metallic ferromagnet. Experimental observation of the phenomenon is not only of fundamental importance. Since it appears in an alloy of common metals at accessible temperatures‚ it holds potential for future exploitation in electronic devices. The discovery is published in the journal Nature.

Standing together against hate: A collective responsibility

Standing together against hate: A collective responsibility

Hate speech incidents are widespread in all areas of society and are often unchallenged by uninvolved bystanders. LMU researchers have investigated what significance the reactions of bystanders to verbal hate attacks have for the formation of social norms.

Study explains how a fungus can control the corn leafhopper‚ an extremely harmful pest

Study explains how a fungus can control the corn leafhopper‚ an extremely harmful pest

The corn leafhopper Dalbulus maidis has become a serious problem for farmers. This tiny insect is now widely distributed in the Americas‚ from the south of the United States to the north of Argentina. In Brazil‚ it uses only corn plants as hosts‚ and little is known about its survival mechanisms in the absence of these plants. In corn‚ it causes damage directly by sucking sap from the phloem‚ the vascular tissue that conducts sugar and other metabolic products downward from the leaves.

Designing a drone that uses adaptive invisibility: Towards autonomous sea-land-air cloaks

Designing a drone that uses adaptive invisibility: Towards autonomous sea-land-air cloaks

The idea of objects seamlessly disappearing‚ not just in controlled laboratory environments but also in real-world scenarios‚ has long captured the popular imagination. This concept epitomizes the trajectory of human civilization‚ from primitive camouflage techniques to the sophisticated metamaterial-based cloaks of today.

How insects tell different sugars apart

How insects tell different sugars apart

Whereas humans have one receptor on their tongues that can detect all sorts of sweet things‚ from real sugar to artificial sweeteners like aspartame‚ insects have many receptors that each detect specific types of sugars. Yale researchers have now uncovered one way insect receptors are able to be so selective‚ an insight they say will help us understand how animals decipher the chemical world and how we might mimic that ability in the future.

New deep-sea worm discovered at methane seep off Costa Rica

New deep-sea worm discovered at methane seep off Costa Rica

Greg Rouse‚ a marine biologist at UC San Diego's Scripps Institution of Oceanography‚ and other researchers have discovered a new species of deep-sea worm living near a methane seep some 50 kilometers (30 miles) off the Pacific coast of Costa Rica. Rouse‚ curator of the Scripps Benthic Invertebrate Collection‚ co-authored a study describing the new species in the journal PLOS ONE.

Genetic mutation in a quarter of all Labradors hard-wires them for obesity

New research finds around a quarter of Labrador retriever dogs face a double-whammy of feeling hungry all the time and burning fewer calories due to a genetic mutation. The results are published in the journal Science Advances.
