Mars rover sees hints of past life in latest rock samples

NASA's Perseverance Mars rover has detected its highest concentrations yet of organic molecules, in a potential signal of ancient microbes that scientists are eager to confirm when the rock samples are eventually brought to Earth.While organic matter has been found on the Red Planet before, the new discovery is seen as especially promising because it came from an area where sediment and salts were deposited into a lake -- conditions where life could have arisen."It is very fair to say that these are going to be, these already are, the most valuable rock samples that have ever been collected," David Shuster, a Perseverance return sample scientist, told reporters during a briefing.Organic molecules -- compounds made primarily of carbon that usually include hydrogen and oxygen, but also at times other elements -- are not always created by biological processes.Further analysis and conclusions will have to wait for the Mars Sample Return mission -- a collaboration between NASA and the European Space Agency (ESA) to bring back the rocks that is set for 2033.Nicknamed Percy, the rover landed on Mars' Jezero Crater in February 2021, tasked with caching samples that may contain signs of ancient life, as well as characterizing the planet's geology and past climate.The delta it is exploring formed 3.5 billion years ago. The rover is currently...

UFO, Humanity & time travel are the signage of positive index

Concerning about Unidentified flying objects (UFO’S) are only relate to the calculation of their positive ability index. As Positive means development and negative means demolishment, and time is the biggest terms move along with population and its exploration with respect to various field of doing. Productivity is the goal to achieve to move along with time or beyond time. It’s called moving in time frame or doing a rate of time travel. With Respect to earth as model humanity is a very big term of time as it's being with pure value of development with coordination.As Human has a brain of vision and program with feel and curiosity which are the nucleus of human so we can say so as human we are on earth for managing the earth resources along with its proper utilization and distributions among each as with nature.So legality is the biggest term of humanity. As it’s manage human in right direction and reduce the rate of resistance among the various field of exploration and their proper integration.As its being with a rate of positive ability index which is defined the rate of development and human movements on earth as well all across the planetary system.As it’s a simple formulation of humanity on earth which moves with positive frame of time with the enhancement of its population which is bounded by legal frame work for the positive...

Are You Ready for Benevolent Artificial Intelligence

Credit: © IMAGO / Jochen Tack                                                                     Autonomous bus, in Monheim, RhinePicture yourself driving on a narrow road in the near future when suddenly another car emerges from a bend ahead. It is a self-driving car with no passengers inside. Will you push forth and assert your right of way, or give way to let it pass? At present, most of us behave kindly in such situations involving other humans. Will we show that same kindness towards autonomous vehicles?Using methods from behavioural game theory, an international team of researchers at LMU Munich and the University of London have conducted large-scale online studies to see whether people would behave as cooperatively with artificial intelligence (AI) systems as they do with fellow humans.Cooperation holds a society together. It often requires us to compromise with others and to accept the risk that they let us down. Traffic is a good example. We lose a bit of time when we let other people pass in front of us and are outraged when others fail to reciprocate our kindness. Will we do the same with machines?The study which is published in the journal iScience...

Boston Dynamics robots dance to show off their agility

Boston Dynamics has released a new video of its entire range of robots, including Atlas, Spot, and Handle, dancing in unison to show off their versatility, and perhaps to celebrate Hyundai’s newfound interests in the MIT spinoff.Massachusetts-based Boston Dynamics has thrown up an impressive and unnerving range of robots of varying shapes dancing to the tune of the Motown classic “Do You Love Me.”The whole gang has hit the dance floor, including the humanoid Atlas first shaking its leg and then joined by Spot the quadruped mobile robot designed for sensing, inspection, and remote operation; Handle, the mobile manipulation robot for moving boxes in the warehouse; Pick, the vision processing solution that uses deep-learning to enable building and depalletising of mixed-SKU pallets, all dancing to the tune in an electrifying dance.The world’s most dynamic humanoid robot, Atlas is a research platform designed to push the limits of whole-body mobility. Atlas’s advanced control system and state-of-the-art hardware give the robot the power and balance to demonstrate human-level agility.Atlas has one of the world’s most compact mobile hydraulic systems. Custom motors, valves, and a compact hydraulic power unit enable Atlas to deliver high power to any of its 28 hydraulic joints for impressive feats of mobility.Boston Dynamics dance video...

What we know about new variants of coronavirus

 Three new variants of COVID-19 have been detected in recent weeks, discoveries which have led to fresh fears across the world because some make the virus up to 70 percent more transmissible. Viruses are known to change and mutate constantly. It is a process which happens as they are passed from person to person over a period of months. So to scientists, it came as no surprise to witness new variants of the disease. While it is difficult to predict where new mutations of the disease will occur, none so far have been found to contain mutations that make the virus deadlier, or more likely to be able to evade vaccines or treatments. One of the first strains reported is known as the UK variant, which has been named VUI-202012/01 (the first Variant Under Investigation in December 2020). This mutation is thought to have first occurred in mid-September in the United Kingdom’s southeast, in the capital London or the county of Kent. Referred to by some experts as the B.1.1.7 lineage, this has rapidly become the dominant strain in cases of COVID-19 in many parts of the UK. It appears to be no more fatal, but is more contagious than the original strain, which has led to the swift return of international travel restrictions and other measures amid the holiday season.It can lead to the same broad symptoms as...
