A feasibility study proposes that the laser and telescope technology on earth could be used as a beacon to attract the attention of aliens.  One needs to direct 1- to 2-megawatt laser through a 30- to 45-meter telescope into space.  The same laser could be sent with a brief message encoded in 5×5 tap code ...

To obtain superfluorescence on-demand, researchers used quantum dots made of lead halide perovskites. They conducted optical experiments at -267°C, which gave the final evidence of superfluorescence. A few materials have a tendency to continuously emit light when they are excited by a laser or any other external source. This mechanism is called fluorescence. However, in many quantum systems, ...

New metal-organic framework can efficiently separate ethane and ethylene to manufacture plastic (polyethylene).  The process runs at room temperatures and requires much less energy.  Generally, manufacturing plastics requires enormous amounts of energy. The most common form of plastic, polyethylene, is made from ethylene – a hydrocarbon molecule found in crude oil refining. To make the manufacturing ...

New optogenetic tool uses laser to ‘switch off’ the electrically excitable cells.  It reduces harmful side effects through artificial ion fluxes that were inevitable with the existing optogenetic inhibitory tools. Optogenetics is a technique that uses light to alter the molecular event in a particular manner in living tissues, mostly neurons that have been genetically modulated to ...

New ghost imaging method measures which gas is present in the atmosphere and at what quantity, with far better accuracy.  It doesn’t require extremely sensitive detectors and powerful light sources to work.  Measuring greenhouse gases in the atmosphere like carbon dioxide, methane, ozone and nitrous oxide is crucial for studying how altering amounts of these gases ...

In the next three decades, the air conditioning units will increase by almost 400% worldwide. This will contribute to hundreds of billions of tons of carbon dioxide emissions by 2050.  By 2100, the use of air conditioners alone will increase the average temperature of Earth by 0.5°C. In developing countries, Air Conditioners (ACs) indicate a ...

In the largest survey of nearby galaxies, researchers observed hundreds of pairs of colliding galaxy nuclei associated with supermassive black holes. They found that black holes expand rapidly during the last stages of galaxy mergers.  The force of gravity draws two galaxies together: light-year by light-year, inch by inch, the galaxies comes closer as the cosmic ...

Researchers develop a new optical cable that can transmit data at the rate of one petabit (1000 terabits) per second.  The fiber is as fine as a human hair and less prone to damage.  Fiber optic cables have revolutionized the network communication ever since their inception about 4 decades ago. These cables use thin strands ...

New algorithm named Squirrel detects weaknesses in the power grid.  It can be applied to all types of hazards, including earthquake, malicious attack, and obstruction caused by squirrels.  What conditions and failures in the infrastructure of electric grids could lead to a dramatic blackout? And how private companies and government organizations could invest in to help ...

A research team has built a near real-time system for the simulation of Earth’s interior and earthquakes.  To do this, they used the world’s fastest supercomputer, Summit.  They are currently addressing issues in helioseismology, exploration geophysics, and global and regional seismology. Recent advances in high-performance hardware and efficient algorithms have enabled researchers to develop high-resolution, three-dimensional ...

Uranium is known to humanity since at least 79 AD when it was used in the ceramic industry (natural oxide form) in several parts of Europe. The chemical element was formally discovered only in 1789, when Martin Heinrich Klaproth, a German chemist stumbled upon a strange, unknown substance (oxide of uranium) during an experiment. Klaproth is ...

Researchers use brain-inspired methods to effectively detect the signals at the receiver’s end. It’s based on the Echo State Network that offers high performance while consuming less energy. Scientists are always seeking more efficient and more reliable communications, for everything from mobile phones and televisions to medical instruments and satellites. The technique that has been ...
