OpenAI’s Jeff Clune told VentureBeat machine learning systems can be taught to overcome “catastrophic forgetting,” which he says can speed the path to AGI.
At 35 meters, the wingspan of the new BAE Systems aircraft equals that of a Boeing 737, yet the plane weighs in at just 150 kilograms, including a 15 kg payload. The unmanned plane, dubbed the PHASA-35 (Persistent High-Altitude Solar Aircraft), made its maiden voyage on 10 February at the Royal Australian Air Force Woomera Test Range in South Australia.
“It flew for just under an hour—enough time to successfully test its aerodynamics, autopilot system, and maneuverability,” says Phil Varty, business development leader of emerging products at BAE Systems. “We’d previously tested other sub-systems such as the flight control system in smaller models of the plane in the U.K. and Australia, so we’d taken much of the risk out of the craft before the test flight.”
The prototype aircraft uses gallium arsenide–based triple-junction solar cell panels manufactured by MicroLink Devices in Niles, Ill. MicroLink claims an energy conversion efficiency of 31 percent for these specialist panels.
The magnetic field in one zone on Mars is about 10 times stronger than scientists expected, and it’s changing rapidly.
New data gathered from NASA’s InSight lander, which has been on the Red Planet for a little over a year now, shows that the planet’s magnetic field fluctuates rapidly. InSight is the first landing mission to carry a magnetic sensor, which allows it to measure these fields from up close.
Researchers at California Polytechnic State University have developed a low-cost approach that improves cell-free biotechnology’s utility for bio-manufacturing and portability for field applications.
Cell-free protein synthesis (CFPS) is a biotechnology that harnesses active cellular machinery in a test tube without the presence of living cells, allowing researchers to directly access and manipulate biochemical processes. Scientists and engineers are looking to utilize cell-free biotechnology for numerous applications including on-demand biomanufacturing of biomaterials and therapeutics, point-of-care diagnostics of disease biomarkers and environmental pollutants, and transformative biochemical education platforms.
Cell-free biotechnology researchers have already made many of these applications a reality in the lab, but getting them to work in the field, clinic and classroom is more difficult. The cellular machinery extracted for use in cell-free biotechnology contains biomolecules such as proteins and RNAs, which break down at warmer temperatures, greatly limiting the shelf life of the cellular machinery. Transporting it from one laboratory to another or taking it out of the lab for field applications requires refrigeration to maintain its activity. Being tethered to the “cold chain” is a fundamental limit to meeting cell-free biotechnology’s potential.
Wuhan Coronavirus in Brazil in time for Carnival — what could possibly go wrong?
BRASILIA (Reuters) — Brazil’s Health Ministry on Wednesday confirmed the first case of a fast-spreading new coronavirus in Latin America, diagnosing a 61-year-old man in Sao Paulo who returned recently from Italy.
Even in this experiment, though, the “psychology” of the algorithm in decision-making is counter-intuitive. For example, in the basketball case, the most important factor in making the decision was actually the player’s jerseys rather than the basketball.
Can You Explain What You Don’t Understand?
While it may seem trivial, the conflict here is a fundamental one in approaches to artificial intelligence. Namely, how far can you get with mere statistical associations between huge sets of data, and how much do you need to introduce abstract concepts for real intelligence to arise?
I wonder how many passengers caught the Wuhan Coronavirus on this flight to LA, but don’t know it because they are asymptomatic.
LOS ANGELES (KABC) — A Korean Air flight attendant was diagnosed with coronavirus shortly after working on a flight to Los Angeles, South Korean media is reporting.
The flight attendant worked on a flight from Incheon to Los Angeles and may have spent time in Los Angeles before boarding a return flight. The same person also had recently worked on an Incheon-Tel Aviv route.

Bizarre it is.
Some truths about the Universe and our experience in it seem immutable. The sky is up. Gravity sucks. Nothing can travel faster than light. Multicellular life needs oxygen to live. Except we might need to rethink that last one.
Scientists have just discovered that a jellyfish-like parasite doesn’t have a mitochondrial genome — the first multicellular organism known to have this absence. That means it doesn’t breathe; in fact, it lives its life completely free of oxygen dependency.
