Controlling self-doping in magnetite with temperature
One of the most abundant iron-containing minerals on Earth, and also the oldest known magnetic material, is magnetite, Fe3O4. Magnetite has applications in many fields, such as the study of paleomagnetism—magnetism in rocks induced at the time of t.....»»
Global hot streak continues. February, winter, world"s oceans all break high temperature marks.
For the ninth straight month, Earth has obliterated global heat records—with February, the winter as a whole and the world's oceans setting new high-temperature marks, according to the European Union climate agency Copernicus......»»
Discovering the world of dolphins and their three "super senses"
Imagine that you're in a comfortable room with your cat. You're both sharing the same space, temperature and lighting. But while you're enjoying the décor, and perhaps a book or the taste of hot chocolate, the cat seems intrigued by something else......»»
New technique developed for measurement of temperature distribution inside single catalyst particle
Chemical reactions are usually accompanied by thermal effects, inevitably resulting in temperature changes in the reaction system. Therefore, temperature is an important parameter in reactions, which can affect chemical thermodynamics and reaction ki.....»»
Open quantum system shows universal behavior
Universal behavior is a central property of phase transitions, which can be seen, for example, in magnets that are no longer magnetic above a certain temperature. A team of researchers from Kaiserslautern, Berlin and Hainan, China, has succeeded for.....»»
Research explores the cooling effects of "scuba-diving" in lizards
Anoles are the scuba-diving champions of the lizard world, able to stay underwater for more than 16 minutes. For animals whose body temperature depends on the environment, time spent in a cool running stream can have some tradeoffs......»»
Ice shell thickness reveals water temperature on ocean worlds
Decades before any probe dips a toe—and thermometer—into the waters of distant ocean worlds, Cornell astrobiologists have devised a novel way to determine ocean temperatures based on the thickness of their ice shells, effectively conducting ocean.....»»
Study reveals that decreased cloud cover dominated rapid spring temperature rise in Central Asia
Central Asia has experienced a faster temperature rise than the global land over the past decades, which has brought unprecedented challenges to the survival and flourishing of life. The role of the drivers and their associated underlying mechanisms.....»»
Silencing a gene could lower cholesterol
Durable repression of a gene that has a role in controlling cholesterol levels, achieved without permanent genome editing, has been demonstrated in a mouse study published in Nature this week......»»
When the music changes, so does the dance: Controlling cooperative electronic states in kagome metals
Playing a different soundtrack is, physically speaking, only a minute change of the vibration spectrum, yet its impact on a dance floor is dramatic. People long for this tiny trigger, and as a salsa changes to a tango completely different collective.....»»
Hot stuff: A new thermal pathway for a high explosive
TATB (1,3,5-triamino-2,4,6-trinitrobenzene) is an important explosive compound because of its extensive use in munitions and worldwide weapons systems. Despite its importance, researchers have been trying to understand its response to temperature ext.....»»
Disinfection tech uses low-temperature plasma to remove E. coli from hydroponically grown crops
A group led by researchers at Nagoya University and Meijo University in Japan has developed a disinfection technology that uses low-temperature plasma generated by electricity to cultivate environmentally friendly hydroponically grown crops. This inn.....»»
Unlocking the heat in mosquito modeling: Exploring disease transmission under climate change
Thermal adaptation is the ability of organisms to adjust their life history traits as the temperature changes. In the case of mosquitoes, these traits can determine their risk of transmitting mosquito-borne diseases and how this risk might change in.....»»
Controlling the microenvironment to promote wound healing and regeneration
The Korea Research Institute of Standards and Science has unveiled a new principle for controlling the microenvironment of biological tissues to promote wound healing and regeneration. This discovery holds significant promise for the development of w.....»»
Temperature, humidity may drive future transmission of parasitic worm infections
As climate changes, temperature isn't the only factor to influence the spread of infectious diseases. Humidity plays a role, too, according to new research published this week (Feb. 25) in Ecology Letters......»»
Researchers design novel microfluidic module for controlling the porosity of manufactured materials
Porous materials are essential for many chemical processes, such as light harvesting, adsorption, catalysis, energy transfer, and even new technologies for electronic materials. Therefore, many efforts have been made to control the porosity of differ.....»»
Protecting the peppers: Unlocking the potential of the sterile insect technique
For the first time, researchers in Canada have investigated the use of the sterile insect technique for controlling populations of the pepper weevil, Anthonomus eugenii, an economically significant crop pest in North America......»»
20°C seems the optimal temperature for life on Earth to thrive: What this means in a warming world
Have you ever wondered about the optimal temperature for life on Earth? For humans, 20°C is comfortable. Any warmer and we work less efficiently because releasing heat requires energy......»»
Video: What does a warming Arctic mean for the future?
The Arctic is experiencing disproportionately higher temperature increases compared to the rest of the planet, triggering a series of cascading effects. This rapid warming has profound implications for global climate patterns, human populations and w.....»»
Study finds quantum state of a rotating superfluid can discharge in three ways
According to a recent study from the University of Helsinki, published in the journal Physical Review Letters, a vortex of a superfluid that has been quantized four times has three ways of dividing, depending on the temperature......»»
Skyrocketing ocean temperatures have scientists scratching their heads
Shattered temperature records have grim implications for hurricane season. Enlarge (credit: jay_zynism via Getty) For nearly a year now, a bizarre heating event has been unfolding across the world’s oceans. In March 20.....»»
