The dark side of the heart makes it easier for people to believe in fake news

Jan Philipp Rudloff, Department of Communication Psychology, Julius Maximilian University, Wurzburg, has always wondered why people often choose to believe in the face of obvious fake news, regardless of the contradiction between facts and rumors. He studied 600 American volunteers with his mentor, Professor Markus Appel, and each subject filled out a wide range of questionnaires, such as "1.5 million fewer jobs in the first three years of Trump than in the last three years of Obama ", "climate change brings more extreme weather", etc.
At the same time, they also evaluated the subjects' tendency to protect their own interests. This characteristic is also called the "dark side of personality": everyone is selfish to a certain extent, but when this selfishness is overdeveloped so that the altruistic motivation that should exist at the same time no longer plays any role, it will cause people's view of the world to be distorted. Analysis shows that the stronger the "dark side of personality" of the participants, that is, the more obvious the extreme egoism of not caring about others, the less they believe in the existence of pure objective facts and opinions. Everything is "ulterior motives". The more they do not believe in objective facts, the more difficult it is to distinguish the authenticity of various types of information. They only believe in what they are willing to believe.

Mars was once hit by a killer asteroid

Current research believes that about 3.5 billion to 3 billion years ago, Mars was covered by a vast shallow sea. On these ancient coastlines, traces of at least two large-scale tsunamis have been found, including large pieces of rock debris washed ashore and special traces that may have left on land rocks as the sea water slowly retreats back to the ocean. The first tsunami could have happened about 3.4 billion years ago, and the second could have happened about 3 billion years ago, when Mars' oceans began to dry up.

Recently, scientists discovered a new impact crater on the surface of Mars, called Pohl, which is likely to be the perpetrator of the first tsunami. The pit is about 110 kilometers in diameter and may be less than 120 meters above the ancient sea surface. Researchers estimate that the asteroid that left the crater is between 3-9 kilometers in diameter, the impact generates energy equivalent to 13 million tons of TNT, and the tsunami wave caused can reach 250 meters high, making the impact large enough for scientists to find geological evidence billions of years later.

The role of bioluminescence in nature
Bioluminescence is one of the most spectacular natural phenomena at night, and it is certain that bioluminescence is not for beauty or joke. In the cruel competition for survival, luminescence is one of the strategies they adopt for different purposes.

Glowing whip algae is a plankton that can use bioluminescence to resist predators.It glows when they sense predators, which makes predators very eye-catching on dark nights, thus attracting the attention of other hunters who feed on these predators. This strategy intended to trigger "black eating black" is quite "wise".

The luminous behavior of predators generally has two uses: seduction and lighting. Small lights hanging in front of the head of the anglerfish are used to lure prey to approach and then launch attacks. Some arowanas can see the red light emitted by other fish. They do not attack the illuminator, but use this light to darkly approach other illuminated prey to improve hunting efficiency.

Fireflies are the most famous luminous creatures. In fact, they emit light to communicate: use luminous to attract spouses. Depending on the species, some are female fireflies glow, while others are male.

Laser communication breaks satellite data transmission record
TBIRD

In May 2022, a small cube satellite equipped with a teraByte InfraRed Delivery (TBIRD) was launched into an orbit 480 kilometers away from the earth. Since then, TBIRD has transmitted terabytes of data through an optical communication link with a terrestrial receiver in California at rates up to 100G per second. This data rate is more than 1,000 times higher than the RF links traditionally used for satellite communications, and is also the highest data rate that a laser link from space to ground can achieve. These record speeds are all achieved by a transmitter about the size of a tissue box.
With the launch of various aerospace equipment, the amount of data transmitted from space to ground is getting larger and larger. Relying on previous radio signals, the communication efficiency of satellites has begun to fail to keep up with the growth of demand. NASA's Ames Research Center commissioned the MIT Lincoln Laboratory to start researching TBIRD in 2014. New laser communication control equipment and new data transmission protocols have greatly improved the performance of laser communications. The laboratory plans to increase the rate to 200G/sec in the near future while further reducing costs.
