Collisions with electrons cool molecular ions
A lone molecule free in cold space will cool by slowing down its rotation—it will spontaneously lose its rotational energy in quantum transitions, typically only once in many seconds. This process can be accelerated, slowed down, or even inverted b.....»»
Team modulates electronic state of single-atom catalysts by CO molecular decoration for efficient methane conversion
Direct methane conversion has advantages such as low energy consumption, fewer processes, and better economics. However, it is difficult to activate methane at room temperature due to the high dissociation energy of C-H bonds of methane. Additionally.....»»
Researchers challenge the limits of molecular memory, opening the door to the development of molecular chips
Some molecules respond to external light pulses by changing their structure and holding certain states that can be switched from one to another. These are commonly referred to as photoswitches and usually have two possible states. Recently, however,.....»»
First observation of photons-to-taus in proton–proton collisions
In March 2024, the CMS collaboration announced the observation of two photons creating two tau leptons in proton–proton collisions. It is the first time that this process has been seen in proton–proton collisions, which was made possible by using.....»»
New method to measure entropy production on the nanoscale
Entropy, the amount of molecular disorder, is produced in several systems but cannot be measured directly. An equation developed by researchers at Chalmers University of Technology in Sweden, and Heinrich Heine University Düsseldorf, now sheds new l.....»»
Uncovering the mysteries of microproteins
Northwestern Medicine scientists have developed a method to identify and characterize microproteins—a development that opens the door for understanding physiology and disease at a molecular level of detail not previously possible, according to find.....»»
Albedo can reduce climate benefit of tree planting: New tool identifies locations with high climate-cooling potential
As efforts to restore tree cover accelerate to help avoid runaway climate change, a new study highlights how restoring tree cover can, in some locations, heat up the Earth rather than cool it by affecting how much sunlight the surface reflects (i.e......»»
DOJ antitrust lawsuit complains that iPhones are cool, says lawyer
One element of the DOJ antitrust lawsuit against Apple addresses iMessage, and Apple’s decision to keep the app exclusive to iPhone. But it goes further than arguing that this is anti-competitive, and attacks the use of green chat bubbles for Andro.....»»
Breaking the ice: Molecular insights into saltwater droplet freezing
In a new study, researchers have observed the freezing of saltwater droplets at a molecular level, offering new insights for de-icing and anti-icing technologies. Contrary to conventional wisdom, these droplets don't conform to the typical freezing p.....»»
The 5 weirdest laptops ever made that you forgot existed
Over the last few decades, there have been more than a few unique laptops with cool features like 3D screens, full-out displays, and even screen on the lid......»»

Decoding the plant world"s complex biochemical communication networks
A Purdue University-led research team has begun translating the complex molecular language of petunias. Their grammar and vocabulary are well hidden, however, within the countless proteins and other compounds that fill floral cells......»»
How cells in plant leaves organize themselves to ensure optimal area for photosynthesis
Plant leaves need a large surface area to capture sunlight for photosynthesis. Dr. Emanuele Scacchi and Professor Marja Timmermans from the Center for Plant Molecular Biology at the University of Tübingen, together with an international team, have n.....»»
Research suggests natural electrical grid deep inside Earth enables many types of microbes to survive
To "breathe" in an environment without oxygen, bacteria in the ground beneath our feet depend upon a single family of proteins to transfer excess electrons (produced during the "burning" of nutrients) to electric hairs called nanowires projecting fro.....»»
How to Stay Cool Without Warming the Planet
The race is on to create climate-friendly air-con technology......»»
2024 Hyundai Santa Fe: 7 cool things
The redesigned 2024 Santa Fe has the design of a conventional sport utility, a longer wheelbase, more upright posture and a rugged XRT trim......»»
Molecular crystal motors move like microbes when exposed to light
At first glance, Rabih O. Al-Kaysi's molecular motors look like the microscopic worms you'd see in a drop of pond water. But these wriggling ribbons are not alive; they're devices made from crystallized molecules that perform coordinated movements wh.....»»
System detects microorganisms that mar the quality of beer
With the aid of molecular biology, the quality of Brazilian beer—the country's most popular alcoholic beverage, especially during the summer—may soon be significantly enhanced......»»
Sequencing the blue whale and Etruscan shrew genomes
The blue whale genome was published in the journal Molecular Biology and Evolution, and the Etruscan shrew genome was published in the journal Scientific Data......»»

Photon-like electrons in a four-dimensional world discovered in a real material
Dirac electrons were predicted by P. Dirac and discovered by A. Geim, both of whom were awarded the Nobel Prize in Physics in 1933 and in 2010, respectively. Dirac electrons behave like photons rather than electrons, for they are considered to have n.....»»
