Swimming robots the size of bacteria can be knocked off course by particles in the fluid they are moving through, but an AI algorithm learns from feedback to get them to their target quickly.
“I hope I stay here until my last dying days.”
Those are the words of Tim Shea, who has come a long way since his days as a homeless man once struggling with heroin addiction. He is now the first person ever to live in a 3D-printed house, according to the home’s maker.
On the outskirts of Austin, Texas, 70-year-old Shea has settled into his 400-square-foot home constructed by 3D printing. His new home is situated in the Community First! Village site, which is comprised of houses for the chronically homeless.
The disturbing series of events during the summer of 2019 resulted in an investigation that made its way to the highest echelons of the Navy.
The LHCb Collaboration at CERN has found particles not behaving in the way they should according to the guiding theory of particle physics—the Standard Model.
The Standard Model of particle physics predicts that particles called beauty quarks, which are measured in the LHCb experiment, should decay into either muons or electrons in equal measure. However, the new result suggests that this may not be happening, which could point to the existence of new particles or interactions not explained by the Standard Model.
Physicists from Imperial College London and the Universities of Bristol and Cambridge led the analysis of the data to produce this result, with funding from the Science and Technology Facilities Council. The result was announced today at the Moriond Electroweak Physics conference and published as a preprint.
Scientists at the Large Hadron Collider (LHC) have recorded some highly unusual data that could point to an entirely new force of nature, which would mean a whole new area of physics. The secret lies in an elusive, unstable particle called a B meson, which isn’t biodegrading according to plan.
The scientists at the European Organization for Nuclear Research (CERN) call B mesons “tantalizing tensions,” since the particles break apart into different amounts of electrons and muons than the standard model of physics predicts they should.
B mesons are paired quarks that move together and rapidly decay. While scientists have noticed several previous anomalies in B mesons, this latest observation in decay mode is an even bigger deal. As the B mesons decay in the LHC, there are more electrons and fewer muons than there should be.
Dedicated to those who argue that life extension is bad because it will create overpopulation problems. In adittion to the fact that natality rates are dangerously decreasing in some developed countries, this is only one example of changes that may will take place well before life extension may create a problem of such type, if ever.
Plenty, an ag-tech startup in San Francisco co-founded by Nate Storey, has been able to increase its productivity and production quality by using artificial intelligence and its new farming strategy. The company’s farm farms take up only 2 acres yet produce 720 acres worth of fruit and vegetables. In addition to their impressive food production, they also manage the production with robots and artificial intelligence.
Physicists could be on the verge of a major breakthrough as new results hint at a challenge to the standard model of particle physics.
There are now more than 1300 Starlink satellites in orbit.
CAPE CANAVERAL, Fla. — A SpaceX Falcon 9 rocket launched a new batch of 60 Starlink internet satellites into orbit early Wednesday (March 24) and nailed a landing at sea to top off the company’s latest successful mission.
The veteran Falcon 9 rocket blasted off from Space Launch Complex 40 here at Cape Canaveral Space Force Station in Florida at 4:28 a.m. EDT (0828 GMT).
Summary: Combining neuroimaging data with artificial intelligence technology, researchers have identified a complex network within the brain that comprehends the meaning of spoken sentences.

Have you ever wondered why you are able to hear a sentence and understand its meaning – given that the same words in a different order would have an entirely different meaning?
Should interest those into links on aging/longevity and neuroscience.
The mammalian center for learning and memory, hippocampus, has a remarkable capacity to generate new neurons throughout life. Newborn neurons are produced by neural stem cells (NSCs) and they are crucial for forming neural circuits required for learning and memory, and mood control. During aging, the number of NSCs declines, leading to decreased neurogenesis and age-associated cognitive decline, anxiety, and depression. Thus, identifying the core molecular machinery responsible for NSC preservation is of fundamental importance if we are to use neurogenesis to halt or reverse hippocampal age-related pathology.
While there are increasing number of tools available to study NSCs and neurogenesis in mouse models, one of the major hurdles in exploring this fundamental biological process in the human brain is the lack of specific NSCs markers amenable for advanced imaging and in vivo analysis. A team of researchers led by Dr. Mirjana Maletić-Savatić, associate professor at Baylor College of Medicine and investigator at the Jan and Dan Duncan Neurological Research Institute at Texas Children’s Hospital, and Dr. Louis Manganas, associate professor at the Stony Brook University, decided to tackle this problem in a rather unusual way. They reasoned that if they could find proteins that are present on the surface of NSCs, then they could eventually make agents to “see” NSCs in the human brain.
