The Future Will Be Shaped by Optimists | Kevin Kelly | TED

Posted by in categories: business, ethics

“Every great and difficult thing has required a strong sense of optimism,” says editor and author Kevin Kelly, who believes that we have a moral obligation to be optimistic. Tracing humanity’s progress throughout history, he’s observed that a positive outlook helps us solve problems and empowers us to forge a path forward. In this illuminating talk, he shares three reasons for optimism during challenging times, explaining how it can help us become better ancestors and create the world we want to see for ourselves and future generations.

NASA awards SpaceX $1.15 billion contract for second Artemis lander mission

Posted by in categories: space travel, sustainability

Starship is getting very close to becoming real. Starship just did a 14 engine static fire which is nearly as powerful as the Saturn V that landed people on the moon. A 33 engine static fire should happen within a month.

In addition, NASA just signed up Starship for a third trip to the moon. They have now signed up for one cargo and two crew missions to the moon for a total of over $4 billion. Other customers have signed up with Starship as well.


KENNEDY SPACE CENTER, Fla. — NASA has awarded SpaceX a $1.15 billion contract to develop an upgraded version of its Starship lunar lander and fly a second crewed mission.

Cyber vulnerability discovered in networks used by spacecraft, aircraft and energy generation systems

Posted by in categories: cybercrime/malcode, energy, internet

A major vulnerability in a networking technology widely used in critical infrastructures such as spacecraft, aircraft, energy generation systems and industrial control systems was exposed by researchers at the University of Michigan and NASA.

It goes after a network protocol and hardware system called time-triggered ethernet, or TTE, which greatly reduces costs in high-risk settings by allowing mission-critical devices (like flight controls and ) and less important devices (like passenger WiFi or data collection) to coexist on the same network hardware. This blend of devices on a single network arose as part of a push by many industries to reduce network costs and boost efficiency.

‘Hydrogen cannot be considered a large-scale solution for heating or transport’, says energy-system study

Posted by in category: energy

It would usually be cheaper to use e-fuels derived from hydrogen — rather than H2 directly — due to system costs, academic paper explains.

What if We Could Make Electronics From Mushrooms? | Mashable

Posted by in categories: physics, sustainability, wearables

From wearable gadgets to battery separators, the future of sustainable tech is starting to look like a mushroom. A team of researchers from the Institute of Experimental Physics in Linz have completed a proof-of-concept study, testing whether mycelium skin could substitute plastic in the production of soft electronics. The scientists used processed skin from the mushroom Ganoderma Lucidum – a saprophytic fungus native to some parts of Europe and China that grows naturally on dead hardwood.

This works by laying electronic components on the fungal skin through a process called physical vapor deposition, used to produce thin materials. The resulting electronic circuit has high thermal stability and can withstand thousands of bending cycles. The researchers say that combining conventional electronics with the biodegradable material could help reduce waste in the production of wearable electronics and sustainable battery separators, among other uses.

Closed-form continuous-time neural networks

Posted by in categories: information science, robotics/AI

Physical dynamical processes can be modelled with differential equations that may be solved with numerical approaches, but this is computationally costly as the processes grow in complexity. In a new approach, dynamical processes are modelled with closed-form continuous-depth artificial neural networks. Improved efficiency in training and inference is demonstrated on various sequence modelling tasks including human action recognition and steering in autonomous driving.

Nuclear fusion experiment just made something very strange happen

Posted by in category: particle physics

In a recent study, charged atoms, also known as ions, have been found to behave strangely during nuclear fusion reactions, in ways that scientists did not expect.

According to a paper published on November 14 in the journal Nature Physics, researchers at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory discovered that when deuterium and tritium ions, which are isotopes of hydrogen with one and two neutrons, respectively—are heated using lasers during laser-fusion experiments, there are more ions with higher energies than expected when a thermonuclear burn starts.

“The process of inertial confinement fusion (ICF) squeezes a small (1mm radius) capsule filled with a layer of frozen deuterium and tritium (isotopes of hydrogen) surrounding a volume of deuterium and tritium gas down to a radius of about 30 micrometers. In the process, these isotopes of hydrogen ionize and a plasma of electrons, deuterium and tritium nuclei [is the result],” Edward Hartouni, a physicist at NIF and a co-author of the paper, told Newsweek.
