Why the Earth has a stubbornly cold place that cools

The earth warms relentlessly. So it’s strange that there is a persistent “cold lump” in the middle of the Atlantic. The cold lump (aka “warming hole”) is like a dazzling fins, easily visible on the latest NASA surface maps. As a whole, the sea’s surface has been heated by nearly 2 degrees Fahrenheit (1 degree Celsius) since 1900 as the …

The world’s largest telescope detects extragalactic neutral hydrogen emissions for the first time

The five-hundred-meter-wide orbital spherical radio telescope (FAST) is a radio telescope located in southwest China. It consists of a fixed bowl with a diameter of 500 m (1,600 ft) constructed in a natural depression in the landscape. It is the world’s largest radio telescope with filled aperture. The five hundred meter open spherical radio telescope (FAST) is the largest telescope …

Research can lead to more effective crystal engineering methods

Researchers at the University of Tokyo and Fudan University use confocal microscopy to observe polymorphic crystallization in outstanding detail. Credit: Institute of Industrial Science, University of Tokyo A team of researchers at the University of Tokyo and Fudan University have studied the crystallization process when more than one structural arrangement is possible. By reducing the noise from random fluctuations, they …

Spacewalkers complete the second last battery upgrade for the space station

Two NASA astronauts have completed the penultimate set of battery changes outside the International Space Station, and have promoted a multi-year project to upgrade the circuit’s power system. Expedition 63 commander Chris Cassidy and Bob Behnken, who embarked on SpaceX’s Crew Dragon spacecraft in late May, completed their second spacewalk together on Wednesday (July 1), five days after battery replacement …

Small quantum fluctuations can actually “kick” large objects

Quantum Funhouse For the first time, researchers noticed that small fluctuations in quantum energy actually “kicked” a large mirror out of alignment – the first significant impact of quantum noise on a human scale. The nudge happened inside the LIGO gravity wave detector. And although it is a fascinating discovery, it actually poses a bit of a practical problem for …

Complete and total Mayhem in a Distant Galaxy Collision

A cluster of galaxies is nothing trivial. The shocks, the turbulence, the energy, because all that matter and energy are merging and interacting. And we can look at all the chaos and devastation as it happens. A team of astronomers look at the galaxy cluster Abell 2255 with the European Low Frequency Array (LOFAR) radio telescope, and their images show …

A rare, ultra-bright star has disappeared without a trace

This site may earn affiliate commissions from the links on this site. Terms. Stars can do many things. They can get hotter, expand, explode and even collapse into a black hole. As a rule, they simply cannot disappear. But that’s what seems to have happened to an ultra-bright star in Aquarius. Astronomers were looking for this well-known star in late …

Scientists observe branched luminous flux for the first time

Credit: American Technion Society A team of researchers from the Technion – Israel Institute of Technology has observed a branched luminous flux for the first time. The results are published in Nature and will be included on the cover of issue July 2, 2020. The study was conducted by Ph.D. student Anatoly (Tolik) Patsyk, in collaboration with Miguel A. Bandres, …

Put zinc on bread wheat leaves

Reza Keshavarz notes the wheat growth stage. Credit: Reza Keshavarz An estimated 17.3% of people worldwide are at risk of inadequate zinc intake; Zinc deficiency is an important human health problem. Increasing the Zn concentration in wheat barley is very important, and management strategies to improve the Zn concentration of cereals can play an important role in the fight against …
