America’s FAA Shifts Gears Slightly on Certifying Future ‘Flying Taxi’ Pilots
But will they face stricter government regulations than anticipated? Long-time Slashdot reader
wired_parrot reports that America’s Federal Aviation Administration has shifted gears โ “revising it certification requirements for eVTOLS from small aircraft to a powered-lift category.” (The original submission cites a “growing number” of issues for the industry to resolve โ and asks whether this raises concerns about the viability of the whole potential eVTOL market.)
Meanwhile, AVWeb reports:
According to a Reuters report, the impetus for the shift came from an ongoing audit by the U.S. Department of Transportation’s Office of the Inspector General. The IG said so-called Urban Air Mobility vehicles present the FAA with “new and complex safety challenges….”
In a written response to a request for clarification, an FAA spokesperson told AVweb:
“The FAA’s top priority is to make sure the flying public is safe. This obligation includes our oversight of the emerging generation of eVTOL vehicles. The agency is pursuing a predictable framework that will better accommodate the need to train and certify the pilots who will operate these novel aircraft.
“Our process for certifying the aircraft themselves remains unchanged. All of the development work done by current applicants remains valid and the changes in our regulatory approach should not delay their projects. As this segment of the industry continues to grow, we look forward to certifying innovative new technologies that meet the safety standards that the public expects and deserves.”

Nuclear Energy: the Case Against
He notes Belgium’s adding a 10-year extension to the life of two of its nuclear reactors, France’s program to build 14 new reactors, and Boris Johnson’s pledge to create supply 25% of the UKs power needs with nuclear energy by 2050.
On the surface, the switch to nuclear makes sense. It would not only enable European countries to meet their ambitious net zero targets, since it produces no CO2. It would also make them less vulnerable to Russian threats, and allow them to stop financing the Russian war machine….
What the Russian takeover of [Ukraine] nuclear facilities exposed is a hazard inherent in all nuclear power. In order for this method of producing electricity to be safe, everything else in society has to be functioning perfectly. Warfare, economic collapse, climate change itself โ all of these increasingly real risks make nuclear sites potentially perilous places. Even without them, the dangers of atomic fission remain, and we must ask ourselves: are they really worth the cost…?
Technological developments, growing international cooperation and rising safety standards did indeed do a great deal to ensure that no major nuclear accident occurred for 25 years after Chernobyl. But the Fukushima explosions demonstrated that such improvements have not eradicated the dangers surrounding nuclear power plants…. Can anything be done to make reactors safer? A new generation of smaller modular reactors, designed from scratch to produce energy, not to facilitate warfare, has been proposed by Bill Gates, and embraced, among others, by Macron. The reactors promised by Gates’s TerraPower company are still at the computer-simulation stage and years away from construction. But his claim that in such reactors “accidents would literally be prevented by the laws of physics” must be taken with a pinch of salt, as there are no laws of war protecting either old or new reactors from attack.
There is also serious concern that the rapid expansion in the number of plants, advocated as a way of dealing with climate change, will increase the probability of accidents. While new technology will help to avoid some of the old pitfalls, it will also bring new risks associated with untried reactors and systems. Responsibility for dealing with such risks is currently being passed on to future generations.
This is the second great risk from nuclear power: even if a reactor runs for its lifetime without incident, you still have a lot of dangerous material left at the end of it. Fuel from nuclear power plants will present a threat to human life and the environment for generations to come, with the half-life of some radioactive particles measured in tens of thousands of years…. Nuclear power plants generally have no alternative to storing their high-level radioactive waste on site….If what we bury today in the New Mexico desert โ the waste created by our nuclear ambitions โ is so repulsive to us, why do we pass it on to others to deal with?
The author’s counter-proposal: expanding the use of renewable energy:
New research should be encouraged, grid infrastructure should be built up, and storage capacity increased. Billions that would otherwise go to new nuclear infrastructure, with all the attendant costs of cleanup that continue for decades and beyond, should be pumped instead into clean energy.
In the meantime, we obviously have an existing nuclear industry, and the solution is not to run away in panic, but to take good care of the facilities that already dot our countryside. We must not abandon the industry to its current state of economic hardship, as that would only mean inviting the next accident sooner rather than later.

San Francisco Police Are Using Driverless Cars As Mobile Surveillance Cameras
“Autonomous vehicles are recording their surroundings continuously and have the potential to help with investigative leads,” says a San Francisco Police department training document obtained by Motherboard via a public records request. “Investigations has already done this several times.”
Privacy advocates say the revelation that police are actively using AV footage is cause for alarm. “This is very concerning,” Electronic Frontier Foundation (EFF) senior staff attorney Adam Schwartz told Motherboard. He said cars in general are troves of personal consumer data, but autonomous vehicles will have even more of that data from capturing the details of the world around them. “So when we see any police department identify AVs as a new source of evidence, that’s very concerning.”
As companies continue to make public roadways their testing grounds for these vehicles, everyone should understand them for what they are — rolling surveillance devices that expand existing widespread spying technologies,” said Chris Gilliard, Visiting Research Fellow at Harvard Kennedy School Shorenstein Center. “Law enforcement agencies already have access to automated license plate readers, geofence warrants, Ring Doorbell footage, as well as the ability to purchase location data. This practice will extend the reach of an already pervasive web of surveillance.”

AT&T Is About To Get Away With Its Bogus $1.99 ‘Administrative Fee’
But again, that’s only a fraction of what AT&T’s own records show it charged: $180 per customer on average since 2015, according to documents. The settlement “represents a refund of approximately 6-11 months of the average fees,” they read. Meanwhile, the lawyers are likely to get $3.5 million. “The estimated payment amount represents a strong result for the Settlement Class, particularly given the substantial risks, costs, and delay of continued litigation,” reads the proposed settlement agreement, going on to list all the ways that the lawyers suing AT&T believe that AT&T might still win the case. […]
Oh, and you won’t even get a check in the mail if you’re still an AT&T customer, assuming this version of the settlement is approved. The money will be credited back to your AT&T account, where AT&T can dip its hand right back in again for that $1.99 — or more if it feels emboldened enough to increase the fee yet again. (Admittedly, the AT&T account could be a more reliable way to make sure customers get money back.) The settlement websites can be found here.
An AT&T spokesperson issued the following response: “We deny the allegations in this lawsuit because we clearly disclose all fees that are charged to our customers. However, we have decided to settle this case to avoid lengthy, expensive litigation.”

The Milky Way’s Black Hole Comes to Light
Black holes were an unwelcome consequence of Albert Einstein’s general theory of relativity, which attributes gravity to the warping of space and time by matter and energy, much as a mattress sags under a sleeper. Einstein’s insight led to a new conception of the cosmos, in which space-time could quiver, bend, rip, expand, swirl and even disappear forever into the maw of a black hole, an entity with gravity so strong that not even light could escape it. Einstein disapproved of this idea, but the universe is now known to be speckled with black holes. Many are the remains of dead stars that collapsed inward on themselves and just kept going. But there seems to be a black hole at the center of nearly every galaxy, ours included, that can be millions or billions of times as massive than our sun. Astronomers still do not understand how these supermassive black holes have grown so big.

Cress Seeds Grown in Moon Dust Raise Hopes for Lunar Crops
“We found that plants do indeed grow in lunar regolith, however they respond as if they are growing in a stressful situation,” said Dr Anna-Lisa Paul, a molecular biologist at the University of Florida. Thale cress, or Arabidopsis thaliana, is a small flowering plant related to broccoli, cauliflower and kale. “It’s not especially tasty,” Paul added. The experiments are the first to investigate whether plants can grow in lunar soil and follow an 11-year effort to obtain the rare material. Because the soil is so precious, Nasa loaned only 12g of it — a few teaspoons — to the researchers who conducted the tests. Scientists have long wondered whether the moon could support crops, but with space agencies now planning to return humans to the surface, and potentially build lunar settlements for visitors, the question has become more pressing.

Blocking Inflammation May Lead To Chronic Pain
These findings are also supported by a separate analysis of 500,000 people in the United Kingdom that showed that those taking anti-inflammatory drugs to treat their pain were more likely to have pain two to ten years later, an effect not seen in people taking acetaminophen or anti-depressants. “Our findings suggest it may be time to reconsider the way we treat acute pain. Luckily pain can be killed in other ways that don’t involve interfering with inflammation,” says Massimo Allegri, a Physician at the Policlinico of Monza Hospital in Italy and Ensemble Hospitalier de la Cote in Switzerland.
