Quantum mechanics prohibits any quantum system from achieving a temperature that is equal to absolute zero. However, using Laser cooling, which is a highly efficient spectroscopic technique, atomic samples could be cooled to near absolute zero thus bringing them to their lowest achievable quantum energy state. Scientists have been advancing this technique for decades now and an important question that arose recently is whether carbon molecules, which are an integral component of life on earth, could be laser-cooled.

Nano-rust: Smart additive for autonomous temperature control

Posted by in categories: biotech/medical, chemistry, food, nanotechnology, robotics/AI

The right temperature ensures the success of technical processes, the quality of food and medicines, or affects the lifetime of electronic components and batteries. Temperature indicators enable to detect (un)desired temperature exposures and irreversibly record them by changing their signal for a readout at any later time.

Of particular interest are small-sized temperature indicators that can be easily integrated into any arbitrary object and subsequently monitor the objects’ temperature history autonomously, i.e. without power supply. Accordingly, the indicators’ signal readout permits to verify successful bonding processes, to uncover temperature peaks in global supply chains, or to localize hot spots in electronic devices.

Prof. Dr. Karl Mandel (Professorship for Inorganic Chemistry) and his research group have succeeded in developing a new type of temperature indicator in the form of a micrometer-sized particle, which differs from previously established, mostly optical indicators mainly due to its innovative magnetic readout method. The results of the research work have now been published in the journal Advanced Materials (“Recording Temperature with Magnetic Supraparticles”).

China Rejects NASA’s Claim That It Plans to ‘Take Over’ the Moon

Posted by in categories: military, space

NASA director Bill Nelson warned that China’s space program was primarily established to be used as an extension of its military rather than for peaceful or scientific purposes.

By Trevor Filseth L

China’s Foreign Ministry issued a condemnation on Monday of reports from the United States that Beijing intends to pursue exclusive control over the Moon in the future, accusing administrators within the U.S. National Aeronautics and Space Administration (NASA) of ignoring facts and speaking “irresponsibly” about China’s space program.

Say Goodbye to Binge Eating: Signal Pathway in Brain That Controls Food Intake Discovered

Posted by in categories: food, neuroscience

A group of scientists has developed an entirely new approach to treating eating disorders.

They showed that a group of nerve cells (so-called AgRP, agouti-related peptide neurons) in the hypothalamus control the release of endogenous lysophospholipids, which in turn control the excitability of nerve cells in the cerebral cortex, which stimulates food intake.

In this process, the crucial step of the signaling pathway is controlled by autotaxin, an enzyme that is responsible for the production of lysophosphatidic acid.

Neuroscientists Built an Ultra Detailed Map of the Brain Motor Cortex, From Mice to Monkeys to Humans

Posted by in categories: biotech/medical, neuroscience

Hundreds of neuroscientists built a ‘parts list’ of the motor cortex, laying groundwork to map the whole brain and better understand brain diseases.

Before you read any further, bring your hand to your forehead.

Aliens Could Be Using Quantum Communications to Talk Across Interstellar Space

Posted by in categories: alien life, mathematics, quantum physics

While we haven’t found any evidence of alien life yet, that doesn’t mean it’s not out there, beyond our reach. Now, a team of researchers has put together a mathematical model showing aliens could potentially be communicating across space – via quantum physics.

Efforts are well underway to make quantum communications a reality here on Earth. The idea is that quantum mechanics provide certain properties that would make information transfer inherently faster and more secure than regular systems… if we can get it to work.

One of the major hurdles to overcome before quantum networks can be established is that they’re very fragile and susceptible to interference. According to this latest study, such networks could fly across space without breaking up.
