Some Japanese bullet trains will soon support premium private suites this October, featuring windows with embedded 5G antennas for steadier onboard Wi-Fi and NTT noise-cancelling cabin tech to reduce train noise. The 5G window antennas are designed to maintain line-of-sight connections as trains race past base stations at up to 285 km/h. The Register reports: Rail operator JR Central announced the new tech late last month and will initially deploy a couple of the suites on six trains. The carrier explained that the antennas come from a Japanese company called AGC that weaves microscopic wires through glass to form an antenna. JR Central will connect the windows to an on-train Wi-Fi router. AGC says rival tech relies on 5G signals reaching a train and then bouncing around inside before reaching the Wi-Fi unit. The company says antennas woven into train windows maintain line of sight to nearby 5G base stations. That matters because JR Central's Shinkansen can achieve speeds of up to 285 km/h, which means they speed past cellular network base stations so quickly that it's frequently necessary to reconnect to another radio. AGC says keeping a line of sight connection means its antennas allow increased 5G signal strength, so Wi-Fi service on board trains should be more stable and speedy. The sound-deadening kit JR Central will deploy is called Personalized Sound Zone (PSZ) and comes from Japan's tech giant NTT. The tech uses the same principles applied to noise-cancelling headphones -- determine the waveform of sound and project an inversion of that waveform that cancels out ambient noise.

Longtime Slashdot reader AmiMoJo shares a report from the Guardian: Households will be called on to boost their consumption of Great Britain's record renewable energy this summer to help balance the power grid and lower energy bills. Under the new plans, people could be encouraged to run dishwashers and washing machines or charge up their electric vehicles when there is more wind and solar power than the electricity grid needs. The plan will be delivered with the help of energy suppliers, which may choose to offer heavily discounted or free electricity to their customers during specific periods when the energy system operator predicts there will be a surplus of electricity. Many suppliers already offer more than 2 million households the opportunity to pay lower rates for electricity used during off-peak hours but this will be the first time that the system operator will use this tool to help balance the grid. The National Energy System Operator (Neso) hopes that by issuing a market notice to call on energy users to increase their consumption it can avoid making hefty payments to turn wind and solar farms off when demand for electricity is low, which are ultimately paid for through energy bills.

An anonymous reader quotes a report from the New York Times: Many scientists have contended that humans have evolved very little over the past 10,000 years. A few hundred generations was just a blink of the evolutionary eye, it seemed. Besides, our cultural evolution -- our technology, agriculture and the rest -- must have overwhelmed our biological evolution by now. A vast study, published on Wednesday in the journal Nature, suggests the opposite. Examining DNA from 15,836 ancient human remains, scientists found 479 genetic variants that appeared to have been favored by natural selection in just the past 10,000 years. The researchers also concluded that thousands of additional genetic variants have probably experienced natural selection. Before the new study, scientists had identified only a few dozen variants. "There are so many of them that it's hard to wrap one's mind around them," said David Reich, a geneticist at Harvard Medical School and an author of the new study. He and his colleagues found that a mutation that is a major risk factor for celiac disease, for example, appeared just 4,000 years ago, meaning the condition may be younger than the Egyptian pyramids. The mutation became ever more common. Today, an estimated 80 million people worldwide have celiac disease, in which the immune system attacks gluten and damages the intestines. The steady rise of the mutation came about through natural selection, the scientists argue. For some reason, people with the mutation had more descendants than people without it -- even though it put them at risk of an autoimmune disorder. Other findings are even more puzzling. The researchers found that genetic variants that raise the odds of a smoking habit have been getting steadily rarer in Europe for the past 10,000 years. Something is working against those variants -- but it can't be the harm from smoking. Europeans have been smoking tobacco for only about 460 years. The scientists can't see from their research so far what forces might be making these variants more or less common. "My short answer is, I don't know," said Ali Akbari, a senior staff scientist at Harvard and an author of the study. The researchers also found that some variants, like the one linked to Type B blood, became much more common in Europe around 6,000 years ago, while others changed direction over time. For example, a TYK2 immune gene variant that may have once been beneficial later became harmful because it increased tuberculosis risk. The study also found signs of natural selection in 44 out of 563 traits. Variants linked to Type 2 diabetes, wider waists, and higher body fat have become less common, possibly because farming and carbohydrate-heavy diets made once-useful fat-storing traits more harmful. Other findings, such as selection favoring genes linked to more years of schooling, are harder to interpret.

Tribblix, the Illumos distribution focused on giving you a classic UNIX-style experience, doesn't only support x86. It also has a branch for SPARC, which tends to run behind its x86 counterpart a little bit and has a few other limitations related to the fact SPARC is effectively no longer being developed. The Tribblix SPARC branch has been updated, and now roughly matches the latest x86 release from a few weeks ago. The graphical libraries libtiff and OpenEXR have been updated, retaining the old shared library versions for now. OpenSSL is now from the 3.5 series with the 3.0 api by default. Bind is now from the 9.20 series. OpenSSH is now 10.2, and you may get a Post-Quantum Cryptography warning if connecting to older SSH servers. 'zap install' now installs dependencies by default. 'zap create-user' will now restrict new home directories to mode 0700 by default; use the -M flag to choose different permissions. Support for UFS quotas has been removed. ↫ Tribblix release notes There's no new ISO yet, so to get to this new m34 release for SPARC you're going to have to install from an older ISO and update from there.

Another Haiku monthly activity report, but this time around, there's actually a big ticket item. Haiku has been in a pretty solid and stable state for a while now, so the activity reports have been dominated by fairly small, obscure changes, but during March a major milestone was reached for the ARM64 port. smrobtzz contributed the bulk of the work, including fixes for building on macOS on ARM64, drivers for the Apple S5L UART, fixes to the kernel base address, clearing the frame pointer before entering the kernel, mapping physical memory correctly, the basics for userland, and more. SED4906 contributed some fixes to the bootloader page mapping, and runtime_loader's page-size checks. Combined, these changes allow the ARM64 port to get to the desktop in QEMU. There's a forum thread, complete with screenshots, for anyone interested in following along. ↫ waddlesplash While it's only in QEMU, this is still a major achievement and paves the way for more people to work on the ARM64 port, possibly increasing its health. There's tons of smaller changes and fixes all over the place, too, as usual, and the team mentions beta 6 isn't quite ready yet, still. Don't let that stop you from just downloading the latest nightly, though - Haiku is mature enough to use it.
