Neuroscientists identify brain circuit that encodes timing of events
When we experience a new event, our brain records a memory of not only what happened, but also the context, including the time and location of the event. A new study from MIT neuroscientists sheds light on how the timing of a memory is encoded in the hippocampus, and suggests that time and space are encoded separately.
In a study of mice, the researchers identified a hippocampal circuit that the animals used to store information about the timing of when they should turn left or right in a maze. When this circuit was blocked, the mice were unable to remember which way they were supposed to turn next. However, disrupting the circuit did not appear to impair their memory of where they were in space.
The findings add to a growing body of evidence suggesting that when we form new memories, different populations of neurons in the brain encode time and place information, the researchers say.
‘Galaxy-sized’ observatory sees potential hints of gravitational waves
Scientists have used a “galaxy-sized” space observatory to find possible hints of a unique signal from gravitational waves, or the powerful ripples that course through the universe and warp the fabric of space and time itself.
The new findings, which appeared recently in The Astrophysical Journal Letters, hail from a U.S. and Canadian project called the North American Nanohertz Observatory for Gravitational Waves (NANOGrav).
For over 13 years, NANOGrav researchers have pored over the light streaming from dozens of pulsars spread throughout the Milky Way Galaxy to try to detect a “gravitational wave background.” That’s what scientists call the steady flux of gravitational radiation that, according to theory, washes over Earth on a constant basis. The team hasn’t yet pinpointed that target, but it’s getting closer than ever before, said Joseph Simon, an astrophysicist at the University of Colorado Boulder and lead author of the new paper.
NASA detects human-made nuclear bubble protecting Earth from radiation; Read
“The human-made frequencies such as the one used for coded or long-distance messaging like contacting submarines deep underwater have been “leaking” into space. This leaked VLF has created a bubble-like barrier around Earth’s atmosphere which is reportedly protecting Earth from charged, radioactive particles. It is also said that the nuclear blast/ blasts have turned into belts of radioactivity around Earth which is now further away than it was in the 1960s.”
NASA has found a nuclear bubble surrounding Earth which is protecting it from Radiation. Know what is the VLF capable of and what is human-induced space weather.
Police Robots Are Not a Selfie Opportunity, They’re a Privacy Disaster Waiting to Happen
The arrival of government-operated autonomous police robots does not look like predictions in science fiction movies. An army of robots with gun arms is not kicking down your door to arrest you. Instead, a robot snitch that looks like a rolling trash can is programmed to decide whether a person looks suspicious —and then call the human police on them. Police robots may not be able to hurt people like armed predator drones used in combat— yet —but as history shows, calling the police on someone can prove equally deadly.
Long before the 1987 movie Robocop, even before Karel Čapek invented the word robot in 1920, police have been trying to find ways to be everywhere at once. Widespread security cameras are one solution—but even a blanket of CCTV cameras couldn’t follow a suspect into every nook of public space. Thus, the vision of a police robot continued as a dream, until now. Whether they look like Boston Dynamics’ robodogs or Knightscope’s rolling pickles, robots are coming to a street, shopping mall, or grocery store near you.
The Orwellian menace of snitch robots might not be immediately apparent. Robots are fun. They dance. You can take selfies with them. This is by design. Both police departments and the companies that sell these robots know that their greatest contributions aren’t just surveillance, but also goodwill. In one brochure Knightscope sent to University of California-Hastings, a law school in the center of San Francisco, the company advertises their robot’s activity in a Los Angeles shopping district called The Bloc. It’s unclear if the robot stopped any robberies, but it did garner over 100000 social media impressions and Knightscope claims the robot’s 193 million overall media impressions was worth over $5.8 million. The Bloc held a naming contest for the robot, and said it has a “cool factor” missing from traditional beat cops and security guards.
Ultra-Fast Space Travel Possible After Scientists Discover Hidden Super-Highways
A space bend just as in sci-fi movies.
Scientists have discovered a network of celestial superhighways caused by gravitational effects of the planet that enable space matters to cover astronomical distances in very less time. The research now calls for more study on the topic to use these paths to send space probes to the far end of our solar system.
China’s Tianwen-1 spacecraft will reach Mars orbit on February 10
The rover won’t land on the Red Planet until May.
China’s Tianwen-1 Mars orbiter and rover are speeding toward the Red Planet and preparing to arrive on Feb. 10, the China National Space Administration (CNSA) has said.
Tianwen-1 has been in space for nearly 24 weeks and was around 81 million miles (130 million kilometers) from Earth and 5.15 million miles (8.3 million km) from Mars on Jan. 3 Beijing time, according to CNSA.
