Scientists have developed an efficient new way to convert methane into methanol at room temperature. The technique could help reduce greenhouse gas emissions and provide a cleaner way to make key products.
While carbon dioxide gets most of the attention, it’s not the only greenhouse gas changing the Earth’s climate. Methane is emitted in smaller amounts but is 34 times more potent, so reducing its levels remains a priority. Excess methane from industrial processes is often burned off, but that produces CO2.
A commonly sought alternative is to convert methane into methanol, which can be used to make a range of products like fuels, plastics and construction materials. The problem is, the conversion process usually requires high temperatures and pressures, which makes it energy-intensive.
Spotted: Although relatively expensive to produce at present, and with storage often cited as a concern, green hydrogen fuel production is increasing. A naturally occurring and superabundant element, hydrogen is popular for several reasons, including the ability to produce it using renewable energy sources. And now, Element 1’s modular, grid-independent hydrogen generation technology is making the fuel even more accessible.
Designed to efficiently convert methanol to hydrogen to electricity, the technology supports both hydrogen fuel cell vehicles and electric vehicles. The company’s catalytic reactor heats a methanol and water feedstock mix before sending it through a membrane purifier for almost 100 per cent fuel cell grade hydrogen.
Because the modular system produces the fuel as needed, the risk of combustion is nearly eliminated, and specialty storage facilities are redundant. This is because the only material that needs to be stored and transported is the methanol and water feedstock. The hydrogen is then produced on-site. Element 1 provides both small and large-scale solutions, as well as a mobile version specifically for refuelling electric vehicles on the go.
NASA has set an aggressive launch target for its following the of the SLS rocket that will carry the flight to space. In an interview with , Jim Free, associate administrator with the agency’s Explorations Systems Development program, said this week NASA is working toward an August 23rd to September 6th launch window for Aretmis 1. “That’s the one we’re targeting,” Free told the outlet. “We’d be foolish not to target that right now. We made incredible progress last week.”
For those keeping track, NASA recently the earliest it could get Artemis 1 in space following a successful fueling test of the SLS was between July 26th and August 10th. Instead, NASA selected the second earliest launch window it had open to it.
Before the flight can get underway, technicians must complete final preparations on the SLS rocket, including replacing a seal that led to a hydrogen leak during its June 20th test. NASA began rolling the SLS back to the Kennedy Space Center’s Vehicle Assembly Building, where staff will work on the launch vehicle, on. “I don’t think we’re stretching ourselves to get there,” Free said. “We’re probably pushing ourselves a little bit, but we’re not going to do something stupid.”
We’re about to have an entirely new perspective on the universe.
The James Webb Space Telescope will release its first high-resolution color images on July 12. One of those images “is the deepest image of our universe that has ever been taken,” said NASA Administrator Bill Nelson during a news conference on Wednesday.
“If you think about that, this is farther than humanity has ever moved before,” Nelson said. “And we’re only beginning to understand what Webb can and will do. It’s going to explore objects in the solar system and atmospheres of exoplanets orbiting other stars, giving us clues as to whether potentially their atmospheres are similar to our own.”
Starlink is faster than ever but is it enough for rural internet users?
While Starlink’s download speeds have increased, Ookla’s Speedtest Intelligence shows that upload speeds decreased by almost 33 percent from 16.29 Mbps during the first quarter of last year to 9.33 Mbps in Q1 2022. At the same time, Starlink’s median latency increased from 40 ms to 43 ms in the U.S. and from 51 ms to 55ms in Canada though these changes are likely negligible for most users.
The U.S. and Canada aren’t the only places Starlink adoption has increased while the service’s speeds have improved as Ookla highlights in its report.

A network of 1,600 video cameras surveils Marseille residents in the name of public safety, but this type of policing tool is rarely useful in solving crimes. Digital rights activists are fighting back.
For Nano the creep of increased surveillance has personal resonance. She grew up in Albania as it lurched between different political regimes in the 1990s. Her father, a politician, opposed the party that was in power for part of that time. “It was a very difficult period for us, because we were all being watched,” she says. Her family suspected that the authorities had installed bugs in the walls of their home. But even in France, freedoms are fragile. “These past five years France has lived for much of the time in a state of emergency,” she says. “I’ve seen more and more constraints put on our liberty.”
Concerns have been raised throughout the country. But the surveillance rollout has met special resistance in Marseille, France’s second-biggest city. The boisterous, rebellious Mediterranean town sits on some of the fault lines that run through modern France. Known for hip bars, artist studios, and startup hubs, it is also notorious for drugs, poverty, and criminal activity. It has one of the most ethnically diverse populations in Europe but is stranded in Provence-Alpes-Côte d’Azur, a region that leans far right. The city pushes back. Its attitude could be summed up by graffiti you might pass as you drive in on the A7 motorway: “La vie est (re)belle.”

Artificial Intelligence is outgrowing the current pace of Hardware Improvements and requires a new kind of technology to keep up and enable future AI Applications. Scientists seem to have found that creating artificial brains out of nanowire can mimic the human brain and power the biggest and smartest AI models ever made at relatively low energy consumption.
Today’s deep neural networks already mimic one aspect of the brain: its highly interconnected network of neurons. But artificial neurons behave very differently than biological ones, as they only carry out computations. In the brain, neurons are also able to remember their previous activity, which then influences their future behavior. This in-built memory is a crucial aspect of how the brain processes information, and a major strand in neuromorphic engineering focuses on trying to recreate this functionality. This has resulted in a wide range of designs for so-called “memristors”: electrical components whose response depends on the previous signals they have been exposed to.

Earlier I posted results. Those posts did not include info here concerning topical E5 human trials to start in a month or so and if the results are good they will start up a U.S. factory. So far, 3 treated rats have a 13% longer lifespan than the max for a lab rat and 3 of them are still alive.
In this video we report on the June 2022 update from Dr. Katcher’s experiment with E5, where he is testing to see how long the rats will stay alive if they are given an E5 injection every 90 days. The experiment appears to be coming to an end with only 3 treated rats still alive. But a new experiment has started as well as a human trial of E5 used topically being planned.
