Harvard scientists 3D print swarm of ‘Bluebot’ synchronized soft robotic fish
Researchers from Harvard University have 3D printed a school of soft robotic fish that are capable of swimming in complex patterns without the aid of Wi-Fi or GPS.
Inspired by the distinctive reef-dwelling surgeonfish, the team’s ‘Bluebots’ feature four fins for precision navigation, and a system of LEDs and cameras that enable them to swarm without colliding. The self-sufficiency of the tiny bots could make them ideal for ecological monitoring applications, in areas that wouldn’t otherwise be accessible to humans.
“Just by observing how far or close they are in a picture, they know how far or close the robot must be in the real world. That’s the trick we play here,” the study’s lead author Florian Berlinger told Wired.
Latest Starlink Satellites Equipped with Laser Communications, Musk Confirms
The latest Starlink satellites launched on Jan. 24 are equipped with laser links, and all Starlink satellites launched next year will be equipped with laser inter-satellite links, Elon Musk, SpaceX chief engineer confirmed on Twitter.
“All sats launched next year will have laser links. Only our polar sats have lasers this year and are v [version] 0.9,” Musk tweeted on Monday.
A Twitter user noticed a difference in a photo of the stack of 10 Starlink satellites deployed on Sunday’s Transporter-1 rideshare mission, and asked Musk if an object that looked like a black pipe was lasers, which he confirmed.
SpaceX launches 143 satellites, successfully completes record-setting mission
The SpaceX Falcon 9 rocket successfully completed a mission to deploy 143 spacecraft and satellites into orbit on Sunday, after which the rocket returned safely to a sea-based landing pad.
The two-stage Falcon 9 rocket took flight on its ‘Transporter-1′ mission after weather considerations caused the planned launch on Saturday to be scrapped.
Falcon 9 carried 133 commercial and government spacecraft, and 10 ‘Starlink’ satellites — the most spacecraft ever deployed on a single mission, according to SpaceX.
Sunday’s mission was the fifth successful launch and landing for Falcon 9, the company said.

Rethinking Energy 2020–2030: 100% Solar, Wind, and Batteries is Just the Beginning
Wow…even I was amazed by these stats and timeline… and I am an unapologetic optimist and futurist who wants to live forever lol.
This video is a synopsis of our research report “Rethinking Energy 2020–2030: 100% Solar, Wind, and Batteries is Just the Beginning” that was published on October 27th, 2020 and is available for download free of charge from our RethinkX website https://www.rethinkx.com/energy.
We are on the cusp of the fastest, deepest, most profound disruption of the energy sector in over a century. Like most disruptions, this one is being driven by the convergence of several key technologies whose costs and capabilities have been improving on consistent and predictable trajectories – namely, solar photovoltaic power, wind power, and lithium-ion battery energy storage.
Our analysis shows that 100% clean electricity from the combination of solar, wind, and batteries (SWB) is both physically possible and economically affordable across the entire continental United States as well as the overwhelming majority of other populated regions of the world by 2030. Adoption of SWB is growing exponentially worldwide and disruption is now inevitable because by 2030 they will offer the cheapest electricity option for most regions.
Coal, gas, and nuclear power assets will become stranded during the 2020s, and no new investment in these technologies is rational from this point forward. But the replacement of conventional energy technology with SWB is just the beginning. As has been the.
Astronomers Confirm That Darksat is About Half as Bright as an Unpainted Starlink
Space-based internet service is poised to revolutionize the internet and bring high-speed connectivity to countless communities worldwide. Programs like SpaceX’s Starlink paint a picture of a bright future for the citizens of the world. Like many revolutionary technological advances, there is a dark side to Starlink.
The constellation of hundreds (and eventually thousands) of satellites reflect light back to the Earth, impinging on the darkness of the skies for professional astronomers and stargazers alike. Astronomers report images and data being disrupted by bright streaks left from the satellites passing through their observational fields of view. One potential solution to this issue is applying a dark coating to the reflective antennae on the satellites’ ground-facing side. In January of 2020, SpaceX launched the experimental DarkSat to test the effectiveness of such a coating. Astronomers around the world observed the new satellite. In December of 2020, a team from the National Astronomical Observatory of Japan (NAOJ) released a paper in The Astrophysical Journal showing detailed measurements of the efficacy of DarkSat.
So what were the results of the study? Is DarkSat an effective solution to the astronomical problem posed by Starlink? As is often the case in such studies, the answer is a little complicated.
WSR: A new Wi-Fi-based system for collaborative robotics
Researchers at Harvard University have recently devised a system based on Wi-Fi sensing that could enhance the collaboration between robots operating in unmapped environments. This system, presented in a paper pre-published on arXiv, can essentially emulate antenna arrays in the air as a robot moves freely in a 2-D or 3D environment.
“The main goal of our paper was to leverage arbitrary 3D trajectories for a robot (UAV or UGV) equipped with an on-board trajectory estimation sensor,” Ninad Jadhav, one of the researchers who carried out the study, told TechXplore. “This allows a Wi-Fi-signal-receiving robot to estimate the spatial direction (in azimuth and elevation) of other neighboring robots by capturing all the wireless signal paths traveling between the transmitting and receiving robot (which we call AOA profile). Additionally, we also characterized how the trajectory shape impacts the AOA profile using Cramer Rao bound.”
In their previous studies, Jadhav and his colleagues focused on robot collaboration scenarios in which the robots followed 2-D trajectories with a limited set of geometries (e.g., linear or curved). The new system they created, on the other hand, is applicable to scenarios where robots are moving freely, following a wider range of trajectories.
Taured Mystery: The Man Who Vanished As Mysteriously As He Came
The Man Said That His Country Has Been In Existence For 1000 Years And Was A Little Puzzled Why His Country Was Called Andorra On The Map.
It was July 1954 when a smartly dressed man arrives at Haneda Airport in Tokyo, Japan. Much like other passengers, he makes his way to customs. But whatever happened from this point onwards have left all puzzled and concerned. When questioned by the customs officers, the mysterious passenger said he was from Taured, also referred to as Taured Mystery. The mystery man claimed that it was the third time he was visiting Japan from his country. But, to the surprise of officers, they couldn’t find any country named Taured. The primary language of the man, described as Caucasian looking with a beard, was French. However, she was purportedly speaking Japanese and many other languages as well.
Officers were perplexed because they had never heard about any such country. The passport of the man was issued by of course the Taured. The passport looked authentic but the place was not recognized.
Location of Taured.
The man was then given a map and asked to point out his country. He immediately man pointed to the area occupied by the Principality of Andorra is at the border of France and Spain. The man said that his country has been in existence for 1000 years and was a little puzzled why his country was called Andorra on the map. The man argued with the customs officers for long and refused to give in.
What Is The Mystery All About?
He was also carrying currencies of different countries, probably because he had made several business trips. The mystery man shared other details like the company for which he was working and the hotel where he stayed. Officials find out that the company which he mentioned existed in Tokyo but not in Taured. Similarly, the hotel he mentioned did exist but hotel employees informed them that no such booking was made. This prompted officers to take the man in custody for further interrogation. Officers were suspicious that he might be some criminal and confiscated his documents and personal belongings. The officers put the mystery man in a nearby hotel whilst they conducted their investigation.
Mystery Man Vanishes Amid Tight Security.
To ensure that the mystery man didn’t escape, two guards were placed on the door. It must be mentioned that the hotel room in which he was staying only had one entry and exit point. But to everyone’s surprise, the man vanished the next morning. Not only that, but all his personal documents had also disappeared. A search was launched to find the man but in vain. The thing that was troubling investigating officers was that he was put up in a room high up in the multi-storey hotel building with no balcony.
