Europe’s natural gas shortage, which has pushed prices to multi-year highs, has revived talk of the EastMed pipeline – a Mediterranean Sea pipeline that could carry gas from Israel to European customers, Chevron Chief Executive Michael Wirth said on Monday at the CERAWeek energy conference.
Wirth downplayed concerns over global oil supplies amid the ongoing Russia-Ukraine war and the subsequent potential for an energy crisis.
The EastMed pipeline, meant to transfer natural gas from Israeli waters to Europe via Greece and Cyprus, was announced in 2016, and several agreements have been signed between the three countries on the subject. The three states aimed to complete the €6 billion project by 2025, but no financing has been secured for it.
Welp, Starship is delayed yet again.
SpaceX CEO Elon Musk tweeted on Friday that there would be “slight delays” ahead for the company’s experimental Mars-bound spacecraft. To blame, the billionaire said, was SpaceX having to dedicated more resources to fighting escalating cyber attacks on Starlink satellites by Russia after the space company sent Ukraine a shipment of its internet terminals.
Starship’s first launch has been delayed numerous times now, with much of it due to pending regulatory approval from the Federal Aviation Administration (FAA). However, this latest instance comes amidst a time of geopolitical turmoil caused by Russia’s invasion of Ukraine.
Traditional wisdom says that 3D printers are unsuitable for manufacturing. There are several reasons for that, including cost, part quality, and time, but labor is one of the most significant challenges. With conventional 3D printers, an operator must remove parts between jobs. That has a cost and slows down large production runs. Belt 3D printers solve this problem and also allow for infinite printing in one axis. Tinybelt, a new 3D printer on Kickstarter right now, makes this technology affordable.
The Tinybelt Kickstarter campaign is currently a third of the way to its $80,000 funding goal and needs your help to reach that goal. But you won’t want to contribute out of a sense of charity — you’ll want to back this campaign because Tinybelt has a lot to offer at an extremely competitive price. Tinybelt’s closest competition, the Creality CR-30 “3DPrintMill,” costs about $1,050. Tinybelt is available on Kickstarter right now for $499. Even at that low price, Tinybelt has a larger build volume than the competition.
As with other belt 3D printers 0, Tinybelt has one axis that is infinite. That means you can print parts as long as you want or print an unlimited number of parts—or both. The other two axes are 300mm and 200mm, which is almost twice the area of the Creality CR-30. A special nozzle made by Slice Engineering for the Mosquito hot end allows for printing at a shallower angle. Other specs are comparable, including the use of a dual-gear Bowden extruder.
NIH-funded study identifies brain cells that form boundaries between discrete events.
Researchers have identified two types of cells in our brains that are involved in organizing discrete memories based on when they occurred. This finding improves our understanding of how the human brain forms memories and could have implications in memory disorders such as Alzheimer’s disease. The study was supported by the National Institutes of Health’s Brain Research Through Advancing Innovative Neurotechnologies (BRAIN) Initiative and published in Nature Neuroscience.
“This work is transformative in how the researchers studied the way the human brain thinks,” said Jim Gnadt, Ph.D., program director at the National Institute of Neurological Disorders and Stroke and the NIH BRAIN Initiative. “It brings to human neuroscience an approach used previously in non-human primates and rodents by recording directly from neurons that are generating thoughts.”

Elon Musk has been doing his best to help Ukraine amid the Russian invasion.
Musk warned Starlink users in Ukraine to turn on the system “only when needed” because they could be targeted amid the invasion.

Neom is the crown jewel of Crown Prince Mohammed bin Salman’s program to overhaul the economy of the world’s largest oil exporter.
Computer engineers at Duke University have developed virtual eyes that simulate how humans look at the world accurately enough for companies to train virtual reality and augmented reality programs. Called EyeSyn for short, the program will help developers create applications for the rapidly expanding metaverse while protecting user data.
The results have been accepted and will be presented at the International Conference on Information Processing in Sensor Networks (IPSN), May 4–6, 2022, a leading annual forum on research in networked sensing and control.
“If you’re interested in detecting whether a person is reading a comic book or advanced literature by looking at their eyes alone, you can do that,” said Maria Gorlatova, the Nortel Networks Assistant Professor of Electrical and Computer Engineering at Duke.
Not long ago, Formlabs launched a new ESD Resin specifically for applications that need to keep parts safe from electrostatic discharge (ESD). Now, the double unicorn has announced the latest member of its selective laser sintering (SLS) range of materials—the new high-performance Nylon 12 GF Powder. Good for 3D printing engineering and manufacturing functional prototypes and end-use parts that require thermal stability and structural rigidity, the newly launched material offers excellent stiffness and is the latest meant for use with the Formlabs Fuse 1 industrial SLS 3D printer, which was released last year.
Formlabs’ Nylon 12 GF powder makes it possible to 3D print parts that are thermally stable, and can maintain their dimensional accuracy under load. In the past, glass-filled Nylon materials have been used for a variety of applications, such as 3D printing a scale model, a prosthetic drum stick, a bike rack, loudspeakers, and even a bar! This particular material—one of many Formlabs is planning to introduce for its industrial Fuse 1 3D printer—is said to be a good choice for printing threads and sockets, strong jigs and fixtures, parts subjected to high temperatures and sustained loading, functional prototypes for compsite parts, and replacement parts.
While hydroelectric dams are capable of generating a lot of electricity, they drastically disrupt the environment. Scientists have now proposed a simpler but still effective alternative, in which electric trucks replace such dams.
In a typical hydroelectric facility, a dam is built across a river, causing a reservoir to form directly upstream of that dam. When a gate in the dam is opened, water from the reservoir flows through and drops down to a lower elevation. As it does so, it spins up turbines which generate electricity.
Unfortunately, formation of the reservoir involves the flooding of land which may previously have contained forests, crops, or even people’s homes.
