Into the Unknown: Environmental Testing of the Europa Clipper Spacecraft

Posted by in category: space

“There still is work to be done, but we’re on track for an on-time launch,” said Europa Clipper Project Manager, Jordan Evans. “And the fact that this testing was so successful is a huge positive and helps us rest more easily.”


Like all spacecraft leading up to their launch date, NASA’s Europa Clipper has been undergoing rigorous tests and checkouts to ensure all systems are functioning properly, with NASA engineers recently subjecting the bus-sized orbiter to extreme environmental testing over a 16-day period to ensure the spacecraft can withstand the harsh conditions it will face during its 4-year science mission to the small, ocean world. These harsh conditions not only include the vacuum of space, but also electromagnetic radiation since it will be flying through Jupiter’s massive and powerful magnetic field throughout its mission.

“These were the last big tests to find any flaws,” said Jordan Evans, who is the Europa Clipper Project Manager at the NASA Jet Propulsion Laboratory (JPL). “Our engineers executed a well-designed and challenging set of tests that put the system through its paces. What we found is that the spacecraft can handle the environments that it will see during and after launch. The system performed very well and operates as expected.”

We’ve glimpsed something that behaves like a particle of gravity

Posted by in categories: particle physics, space

Gravitons, the particles thought to carry gravity, have never been seen in space – but something very similar has been detected in a semiconductor.

Brain Implants Allow Paralyzed Man to Walk Using His Thoughts

Posted by in categories: biotech/medical, neuroscience

Gert-Jan Oskam was living in China in 2011 when he was in a motorcycle accident that left him paralyzed from the hips down.


In a new study, researchers describe a device that connects the intentions of a paralyzed patient to his physical movements.

Neuroscientist Andrew Huberman Accused of Bizarre Behavior

Posted by in category: neuroscience

In an alarming exposé, several women have come forward accusing neuroscientist and celebrated podcaster Andrew Huberman of manipulation, bizarre behavior, and infidelity that may have led to a sexually transmitted infection in at least one of them.

Published by New York Magazine, this deep dive into the disparate public and private lives of the Stanford University neuroscientist illustrates a jarring portrait of a man who promotes physical and mental health and wellness — but engaged in bizarre interpersonal behavior, including secretly dating five women simultaneously.

Much of the story centers around a woman whom NYMag calls Sarah, who spent years dating the “Huberman Lab” host in what she believed to be an exclusive relationship. Along with accusing the 48-year-old podcaster of obfuscating about his other relationships, Sarah described Huberman as being intense and controlling, including — in a particularly unhinged twist — constantly relitigating her romantic and reproductive decisions from back before they were together.

Quantum interference could lead to smaller, faster, and more energy-efficient transistors

Posted by in categories: chemistry, computing, nanotechnology, particle physics, quantum physics

As transistors get smaller, they become increasingly inefficient and susceptible to errors, as electrons can leak through the device even when it is supposed to be switched off, by a process known as quantum tunneling. Researchers are exploring new types of switching mechanisms that can be used with different materials to remove this effect.

In the nanoscale structures that Professor Jan Mol, Dr. James Thomas, and their group study at Queen Mary’s School of Physical and Chemical Sciences, quantum mechanical effects dominate, and electrons behave as waves rather than particles. Taking advantage of these quantum effects, the researchers built a new transistor.

The transistor’s conductive channel is a single zinc porphyrin, a molecule that can conduct electricity. The porphyrin is sandwiched between two graphene electrodes, and when a voltage is applied to the electrodes, electron flow through the molecule can be controlled using .

Predicting and Controlling Bad Actor Artificial Intelligence

Posted by in categories: cybercrime/malcode, government, internet, mapping, robotics/AI

This article includes computer-generated images that map internet communities by topic, without specifically naming each one. The research was funded by the US government, which is anticipating massive interference in the 2024 elections by “bad actors” using relatively simple AI chat-bots.


In an era of super-accelerated technological advancement, the specter of malevolent artificial intelligence (AI) looms large. While AI holds promise for transforming industries and enhancing human life, the potential for abuse poses significant societal risks. Threats include avalanches of misinformation, deepfake videos, voice mimicry, sophisticated phishing scams, inflammatory ethnic and religious rhetoric, and autonomous weapons that make life-and-death decisions without human intervention.

During this election year in the United States, some are worried that bad actor AI will sway the outcomes of hotly contested races. We spoke with Neil Johnson, a professor of physics at George Washington University, about his research that maps out where AI threats originate and how to help keep ourselves safe.
