Researchers realize high-efficiency frequency conversion on integrated photonic chip
A team led by Prof. GUO Guangcan and Prof. ZOU Changling from the University of Science and Technology of China of the Chinese Academy of Sciences realized efficient frequency conversion in microresonators via a degenerate sum-frequency process, and achieved cross-band frequency conversion and amplification of converted signal through observing the cascaded nonlinear optical effects inside the microresonator. The study was published in Physical Review Letters.

Evading the uncertainty principle in quantum physics
The uncertainty principle, first introduced by Werner Heisenberg in the late 1920's, is a fundamental concept of quantum mechanics. In the quantum world, particles like the electrons that power all electrical product can also behave like waves. As a result, particles cannot have a well-defined position and momentum simultaneously. For instance, measuring the momentum of a particle leads to a disturbance of position, and therefore the position cannot be precisely defined.

The Mars Helicopter, Ingenuity, is a technology demonstration to test powered, controlled flight on another world for the first time. It hitched a ride to Mars on the Perseverance rover. Once the rover reached a suitable "airfield" location, it released Ingenuity to the surface so it could perform a series of test flights over a 30-Martian-day experimental window.
The helicopter completed its technology demonstration after three successful flights. For the first flight on April 19, 2021, Ingenuity took off, climbed to about 10 feet (3 meters) above the ground, hovered in the air briefly, completed a turn, and then landed. It was a major milestone: the very first powered, controlled flight in the extremely thin atmosphere of Mars, and, in fact, the first such flight in any world beyond Earth. After that, the helicopter successfully performed additional experimental flights of incrementally farther distance and greater altitude.

In 2019, the first-ever image of a black hole wowed the world. And now, the team at the Event Horizon Telescope has released an updated version, this time revealing how the supermassive black hole looks in polarized light.
Paradoxically, despite their light-swallowing capability, black holes are the most luminous objects in the universe. Material — gas, dust, shredded stars — that falls into a black hole is heated to millions of degrees as it swirls around the drain of doom in a dense maelstrom of electromagnetic fields. Most of that matter falls into the black hole, but some is pushed out, like toothpaste, by enormous pressures and magnetic fields. How all of this energy arises and is marshaled remains unknown to astronomers.
The black hole in question is a monster 6.5 billion times as massive as the sun, and lies in the center of an enormous elliptical galaxy, Messier 87, about 55 million light-years away in the constellation Virgo.

Researchers generate tunable twin particles of light
Identical twins might seem 'indistinguishable,' but in the quantum world the word takes on a new level of meaning. While identical twins share many traits, the universe treats two indistinguishable quantum particles as intrinsically interchangeable. This opens the door for indistinguishable particles to interact in unique ways—such as in quantum interference—that are needed for quantum computers.

Is the past (and future) there when nobody looks?
In 1961, the Nobel prize winning theoretical physicist Eugene Wigner proposed what is now known as the 'Wigner's friend' thought experiment as an extension of the notorious Schroedinger's cat experiment. In the latter, a cat is trapped in a box with poison that will be released if a radioactive atom decays. Governed by quantum mechanical laws, the radioactive atom is in a superposition between decaying and not decaying, which also means that the cat is in a superposition between life and death. What does the cat experience when it is in the superposition? Wigner sharpened the question by pushing quantum theory to its conceptual limits. He investigated what happens when an observer also has quantum properties.

Gravity increases as we get close to the center of the Earth.
Gravity actually increases slightly as you get closer to the center of the Earth, reaching a maximum at the core-mantle boundary due to an increase in density of the core material.

Previously unknown letter reveals Einstein's thinking on bees, birds and physics
Could bees and birds help us understand the principles of physics? Albert Einstein thought so, according to a long-lost letter that reveals he predicted a link between physics and biology seven decades before the evidence emerged.
