Energy Prices Drop Below Zero In UK Thanks To Record Wind-Generated Electricity
Long-time Slashdot AmiMoJo quotes this report from EcoWatch:
Record wind-generated electricity across Northern Ireland and Scotland Tuesday night pushed Britain’s power prices below zero. Wind output peaked at a record high 22.4 gigawatts (GW), breaking the previous high set [last] Sunday evening, the national system operator said, as Bloomberg reported. The record output provided more than 68 percent of the country’s power. From 5:30 to 6:30 a.m. on Wednesday, the half-hourly price fell to 6.57 pounds per megawatt-hour, according to data from European power exchange Epex Spot.
“Setting another clean electricity generation record just four days after the previous high shows the pivotal role wind is playing in keeping the country powered up during the festive season,” said Dan McGrail, chief executive of RenewableUK, as . “This is also demonstrated by today’s official figures which reveal that renewables have generated more than half our electricity for four quarters in a row.”
The article adds that energy prices with negative numbers “have been recorded for 131 hours in the UK this year, an increase of 45 hours over 2023…
“Wind power was the largest source of energy in the UK from January to September of 2024.”

Apple Reportedly Plans a Doorbell That Unlocks Your Door With Face ID
Engadget reports:
Apple is developing a smart doorbell and lock system that would use Face ID to unlock the door for known residents, Mark Gurman reports in the Power On newsletter. The face-scanning doorbell would connect to a smart deadbolt, which could include existing HomeKit-compatible third-party locks, according to Gurman. Or, Apple may “[team] up with a specific lock maker to offer a complete system on day one.”
The Power On newsletter also reports that Apple is testing “health” features like heart rate monitoring and temperature sensing for its AirPods Pro earbuds…

Aging Isn’t Linear, Researchers Discover: ‘Dramatic Change’ in Mid-40s, Early 60s
An anonymous reader shared this report from Health magazine:
“Most people think of aging as occurring gradually, constantly, and linearly,” senior study author Michael Snyder, PhD, a professor of genetics and director of the Center for Genomics and Personalized Medicine at Stanford University, told Health. But “we’re not just changing gradually over time; there are some really dramatic changes,” Snyder said in a news release. “It turns out the mid-40s is a time of dramatic change, as is the early 60s. And that’s true no matter what class of molecules you look at.”
And these molecular changes aren’t insignificant to our health — they were seen in molecules related to cardiovascular disease, skin and muscle health, immune regulation, and kidney function, among others… [R]esearchers from Stanford University and Nanyang Technological University in Singapore used data from 108 participants between the ages of 25 and 75. Those participants donated blood and other biological samples (stool samples, oral and nasal swabs) every few months over the course of several years. From those samples, researchers were able to track age-related changes in more than 135,000 different molecules and microbes in the participants’ bodies.
The analysis showed that the majority of molecules and microbes underwent major changes in their abundance (increasing or decreasing) during two time periods: when people were in their mid-40s and early 60s… The molecules that showed extreme changes in a person’s 40s, for example, were related to alcohol, caffeine, and lipid metabolism, as well as cardiovascular disease and skin and muscle health. Meanwhile, molecular changes in a person’s 60s were related to carbohydrate and caffeine metabolism, immune regulation, kidney function, cardiovascular disease, and skin and muscle health. According to experts, these changes might show up as a reduced ability to metabolize caffeine and alcohol, suggesting that it may be wise to cut back on those substances. People in their 40s and 60s may also see a greater risk of developing cardiovascular disease, and people in their 60s may benefit from supporting their immune systems.
The article ends with this advice from Dr. Ronald DePinho, a cancer biology professor at the University of Texas’s cancer center: there’s ways to manage or slow some of the changes associated with aging.
“The easiest way to do that is through lifestyle changes, said DePinho — that means staying active, eating and sleeping well, managing stress, and avoiding smoking and excessive alcohol.”

With Drones Over US Military Bases, Agencies Urge Congress to Pass Drone-Defense Legislation
A series of drone sightings over U.S. military bases “has renewed concerns that the U.S. doesn’t have clear government-wide policy for how to deal with unauthorized incursions that could potentially pose a national security threat,” reports CNN:
“We’re one year past Langley drone incursions and almost two years past the PRC spy balloon. Why don’t we have a single [point of contact] who is responsible for coordination across all organizations in the government to address this?” the recently retired head of US Northern Command and NORAD, Gen. Glen VanHerck, told CNN. “Instead, everybody’s pointing their fingers at each other saying it’s not our responsibility….” Over a period of six days earlier this month, there were six instances of unmanned aerial systems, or drones, entering the airspace of the Marine Corps base Camp Pendleton in California, a spokesperson confirmed to CNN, adding that they posed “no threat to installation operations and no impact to air and ground operations.” There have also been incidents in the last month at Wright-Patterson Air Force Base, Ohio; Picatinny Arsenal, New Jersey; Naval Weapons Station Earle, New Jersey; and Vandenberg Space Force Base, California. A Chinese citizen, who is a lawful permanent resident of the US, was recently arrested in connection to the California incident.
The drone incidents are “a problem that has been brewing for over a decade and we have basically failed to address it,” said retired Air Force Brig. Gen. Rob Spalding, who previously served as the chief China strategist for the Joint Chiefs of Staff and senior director for strategic planning on the National Security Council. It’s unclear what specifically the drones could be doing — the intent could be anything from attempting to gather intelligence on the base or testing its defenses and response time, to gaining a better understanding of how the bases work, or they could simply be harmless hobbyists flying drones too close to restricted areas… Despite the incursions and the risk they could pose, officials say there is no coordinated policy to determine what agency leads the response to such activity, or how to determine where the drones originate.
CNN reported this week that government agencies have struggled to keep pace with the development of drones and drone technology, particularly by adversaries like China, though legislation is being discussed and the Pentagon just recently released its strategy for countering unmanned systems… The two heads of the Senate Armed Services Committee, Sens. Jack Reed and Roger Wicker, sounded the alarm in a Washington Post op-ed at the beginning of 2024 that the US “lacks adequate drone detection capability” and that agencies “lack clear lines of authority about which agency is responsible for stopping these incursions.”
Military installations have the authority to protect themselves and respond to threats, but a former senior military official said that if the drone enters the airspace and subsequently leaves, determining where the drone originated from and what it was doing can be difficult. Military law enforcement typically coordinates with civilian law enforcement off base in that instance, the former official said, but are often limited in what they can do given laws that restrict intelligence collection within US borders. But sources also said the lack of ability to do more also stems at times from a failure to prioritize defense against this kind of activity within the US. The topic is “such a relatively new phenomenon that the law has not caught up and the agencies have not adapted quickly enough,” [said one Senate aide familiar with discussions on drone defense and policy].
“The need for Congressional action was made clear in a joint statement this week from the Department of Defense, Department of Homeland Security, Federal Bureau of Investigations and Federal Aviation Administration,” according to the article.
“The agencies said they ‘urge Congress to enact counter-UAS legislation when it reconvenes that would extend and expand existing counter-drone authorities to identify and mitigate any threat that may emerge.'”

Albania Will Close TikTok for One Year, Saying It Encourages Violence Among Children
The Associated Press reports that in Albania (population: 2,402,113), “children comprise the largest group of TikTok users in the country, according to domestic researchers.”
But “Albania’s prime minister said Saturday the government will shut down the video service TikTok for one year, blaming it for inciting violence and bullying, especially among children” after “the stabbing death of a teenager in mid-November by another teen after a quarrel that started on TikTok.”
There has been increasing concern from Albanian parents after reports of children taking knives and other objects to school to use in quarrels or cases of bullying promoted by stories they see on TikTok. TikTok’s operations in China, where its parent company is based, are different, “promoting how to better study, how to preserve nature … and so on,” according to Rama. Albania is too small a country to impose on TikTok a change of its algorithm so that it does not promote “the reproduction of the unending hell of the language of hatred, violence, bullying and so on,” Rama’s office wrote in an email response to The Associated Press’ request for comment. Rama’s office said that in China TikTok “prevents children from being sucked into this abyss.”
TikTok told the Associated Press it “found no evidence that the perpetrator or victim had TikTok accounts, and multiple reports have in fact confirmed videos leading up to this incident were being posted on another platform, not TikTok….”

The Theory That Volcanoes Killed the Dinosaurs Is Officially Extinct
“Sixty-six million years ago, all dinosaurs (except for birds) were wiped from the face of the Earth…” writes Gizmodo. “What’s indisputable about this pivotal moment in Earth’s history is that a 6.2 to 9.3-mile-wide (10 to 15-kilometer) asteroid struck what is now modern-day Mexico. Around the same time, however, volcanoes in what is now India experienced some of the largest eruptions in Earth’s history.”
Those volcanos “have long been proposed as an alternative cause for the demise of the dinosaurs…” writes Phys.org. But “Now, climate scientists from Utrecht University and the University of Manchester show that while the volcanism caused a temporary cold period, the effects had already worn off thousands of years before the meteorite impacted.”
Earth scientists have fiercely debated for decades whether a massive outpouring of lava on the Indian continent, which occurred both prior to and after the meteorite impact, also contributed to the demise of dinosaur populations roaming Earth. These volcanic eruptions released vast amounts of CO2, dust, and sulfur, thereby significantly altering the climate on Earth — but in different ways and on different timescales to a meteorite impact. The new publication provides compelling evidence that while the volcanic eruptions in India had a clear impact on global climate, they likely had little to no effect on the mass extinction of the dinosaurs.
By analyzing fossil molecules in ancient peats from the United States of America, the scientific team reconstructed air temperatures for the time period covering both the volcanic eruptions and the meteorite impact. Using this method, the researchers show that a major volcanic eruption occurred about 30,000 years before the meteor impact, coinciding with at least a 5 degrees Celsius cooling of the climate… Importantly, the scientists discovered that by around 20,000 years before the meteorite impact, temperatures on Earth had already stabilized and had climbed back to similar temperatures before the volcanic eruptions started.
The study is published in the journal Science Advances. And Gizmodo shares this quote from Bart van Dongen of The University of Manchester, who worked on the research.
“The study provides vital insights not only into the past but could also help us find ways for how we might prepare for future climate changes or natural disasters.”

Sea Levels are Already Rising in America’s Southeast. A Preview of the Future?
The Washington Post visits one of over 100 tide-tracking stations around the U.S. — Georgia’s Fort Pulaski tide gauge:
Since 2010, the sea level at the Fort Pulaski gauge has risen by more than 7 inches, one of the fastest rates in the country, according to a Washington Post analysis of National Oceanic and Atmospheric Administration data for 127 tide gauges. Similar spikes are affecting the entire U.S. Southeast — showing a glimpse of our climate future… [I]n the previous 30 years, the ocean rose about 3.7 inches. And the deluge stretches all across the South and the Gulf Coast; over the past 14 years, sea levels in the U.S. South have risen twice as fast as the global average…
Scientists suspect part of that is because of the Gulf Stream — a long band of warm water that follows the coast up from the equator and then, near Cape Hatteras, turns out into the Atlantic Ocean. The waters of the Gulf Stream and the Gulf of Mexico are warming faster than other parts of the Atlantic, boosting sea levels. “The Gulf of Mexico has warmed exceptionally fast over the past decade and a half,” Piecuch said. “It’s uncontroversial.” But scientists have puzzled over where all that heat is coming from… [T]he current heat could be part of long-term variations in ocean currents, and not a clear signal of climate change. But the fact that the change is linked to heat — at the same time as the entire ocean is taking on excess heat from global warming — makes some experts suspicious. “This particular mechanism does not immediately suggest it’s just natural variability,” [said Ben Hamlington, a research scientist who leads NASAâ(TM)s sea level change team].
For now, sea levels in the Southeast are surging — and they provide an early picture of what most of the United States, and the rest of the world, will experience as oceans rise… On Tybee Island — whose population of 4,000 swells to over 100,000 during the summer months — leaders have gotten used to the constant fight against the waves. Five or six times a year, high tides sweep over the one road that connects the island to the mainland, cutting residents off from services. By 2050, scientists estimate, those high tides will happen 70 days a year. With the help of the U.S. Army Corps of Engineers, the city has built dunes to protect vacation homes and local storefronts from the rising water; many homeowners have also raised their properties high up into the air. In Savannah, small businesses and city streets are washed in floods even on bright, sunny days — thanks to high tides that surge into the drainage system. The city estimates that it will cost $400 million to update the stormwater infrastructure over the next two decades. So far, it has raised $150 million…
Other states and cities will soon see the same effects. NASA projections show that in the coming decades, many cities in the Northeast will experience up to 100 more days of high-tide flooding each year.
“Some researchers think that the Southeast acceleration may be linked to long-term weather patterns in the Atlantic Ocean like the North Atlantic Oscillation.
“If so, the trend could switch in the coming decades — with areas of the Northeast seeing rapid sea level rise while the trend in the Southeast slows down.”

OpenAI’s Next Big AI Effort GPT-5 is Behind Schedule and Crazy Expensive
“From the moment GPT-4 came out in March 2023, OpenAI has been working on GPT-5…” reports the Wall Street Journal. [Alternate URL here.] But “OpenAI’s new artificial-intelligence project is behind schedule and running up huge bills. It isn’t clear when — or if — it’ll work.”
“There may not be enough data in the world to make it smart enough.”
OpenAI’s closest partner and largest investor, Microsoft, had expected to see the new model around mid-2024, say people with knowledge of the matter. OpenAI has conducted at least two large training runs, each of which entails months of crunching huge amounts of data, with the goal of making Orion smarter. Each time, new problems arose and the software fell short of the results researchers were hoping for, people close to the project say… [And each one costs around half a billion dollars in computing costs.]
The $157 billion valuation investors gave OpenAI in October is premised in large part on [CEO Sam] Altman’s prediction that GPT-5 will represent a “significant leap forward” in all kinds of subjects and tasks…. It’s up to company executives to decide whether the model is smart enough to be called GPT-5 based in large part on gut feelings or, as many technologists say, “vibes.”
So far, the vibes are off…
OpenAI wants to use its new model to generate high-quality synthetic data for training, according to the article. But OpenAI’s researchers also “concluded they needed more diverse, high-quality data,” according to the article, since “The public internet didn’t have enough, they felt.”
OpenAI’s solution was to create data from scratch. It is hiring people to write fresh software code or solve math problems for Orion to learn from. [And also theoretical physics experts] The workers, some of whom are software engineers and mathematicians, also share explanations for their work with Orion… Having people explain their thinking deepens the value of the newly created data. It’s more language for the LLM to absorb; it’s also a map for how the model might solve similar problems in the future… The process is painfully slow. GPT-4 was trained on an estimated 13 trillion tokens. A thousand people writing 5,000 words a day would take months to produce a billion tokens.
OpenAI’s already-difficult task has been complicated by internal turmoil and near-constant attempts by rivals to poach its top researchers, sometimes by offering them millions of dollars… More than two dozen key executives, researchers and longtime employees have left OpenAI this year, including co-founder and Chief Scientist Ilya Sutskever and Chief Technology Officer Mira Murati. This past Thursday, Alec Radford, a widely admired researcher who served as lead author on several of OpenAI’s scientific papers, announced his departure after about eight years at the company…
OpenAI isn’t the only company worrying that progress has hit a wall. Across the industry, a debate is raging over whether improvement in AIs is starting to plateau. Sutskever, who recently co-founded a new AI firm called Safe Superintelligence or SSI, declared at a recent AI conference that the age of maximum data is over. “Data is not growing because we have but one internet,” he told a crowd of researchers, policy experts and scientists. “You can even go as far as to say that data is the fossil fuel of AI.”
And that fuel was starting to run out.

It’s more language for the LLM to absorb; it’s also a map for how the model might solve similar problems in the future… The process is painfully slow. GPT-4 was trained on an estimated 13 trillion tokens. A thousand people writing 5,000 words a day would take months to produce a billion tokens.
OpenAI’s already-difficult task has been complicated by internal turmoil and near-constant attempts by rivals to poach its top researchers, sometimes by offering them millions of dollars… More than two dozen key executives, researchers and longtime employees have left OpenAI this year, including co-founder and Chief Scientist Ilya Sutskever and Chief Technology Officer Mira Murati. This past Thursday, Alec Radford, a widely admired researcher who served as lead author on several of OpenAI’s scientific papers, announced his departure after about eight years at the company…
OpenAI isn’t the only company worrying that progress has hit a wall. Across the industry, a debate is raging over whether improvement in AIs is starting to plateau. Sutskever, who recently co-founded a new AI firm called Safe Superintelligence or SSI, declared at a recent AI conference that the age of maximum data is over. “Data is not growing because we have but one internet,” he told a crowd of researchers, policy experts and scientists. “You can even go as far as to say that data is the fossil fuel of AI.”
And that fuel was starting to run out.

Scientists Build a Nuclear-Diamond Battery That Could Power Devices for Thousands of Years
The world’s first nuclear-powered battery — a diamond with an embedded radioactive isotope — could power small devices for thousands of years, according to scientists at the UK’s University of Bristol.
Long-time Slashdot reader fahrbot-bot shared this report from LiveScience:
The diamond battery harvests fast-moving electrons excited by radiation, similar to how solar power uses photovoltaic cells to convert photons into electricity, the scientists said.
Scientists from the same university first demonstrated a prototype diamond battery — which used nickel-63 as the radioactive source — in 2017. In the new project, the team developed a battery made of carbon-14 radioactive isotopes embedded in manufactured diamonds. The researchers chose carbon-14 as the source material because it emits short-range radiation, which is quickly absorbed by any solid material — meaning there are no concerns about harm from the radiation. Although carbon-14 would be dangerous to ingest or touch with bare hands, the diamond that holds it prevents any short-range radiation from escaping. “Diamond is the hardest substance known to man; there is literally nothing we could use that could offer more protection,” Neil Fox, a professor of materials for energy at the University of Bristol, said in the statement…
A single nuclear-diamond battery containing 0.04 ounce (1 gram) of carbon-14 could deliver 15 joules of electricity per day. For comparison, a standard alkaline AA battery, which weighs about 0.7 ounces (20 grams), has an energy-storage rating of 700 joules per gram. It delivers more power than the nuclear-diamond battery would in the short term, but it would be exhausted within 24 hours. By contrast, the half-life of carbon-14 is 5,730 years, which means the battery would take that long to be depleted to 50% power….
[A] spacecraft powered by a carbon-14 diamond battery would reach Alpha Centauri — our nearest stellar neighbor, which is about 4.4 light-years from Earth — long before its power were significantly depleted.
The battery has no moving parts, according to the article. It “requires no maintenance, nor does it have any carbon emissions.”

Months After Its 20th Anniversary, OpenStreetMap Suffers an Extended Outage
Monday long-time Slashdot reader denelson83 wrote: The crowdsourced, widely-used map database OpenStreetMap has had a hardware failure at its upstream ISP in Amsterdam and has been put into a protective read-only mode to avoid loss or corruption of data. .
The outage had started Sunday December 15 at 4:00AM (GMT/UTC), but by Tuesday they’d posted a final update:
Our new ISP is up and running and we have started migrating our servers across to it. If all goes smoothly we hope to have all services back up and running this evening…
We have dual redundant links via separate physical hardware from our side to our Tier 1 ISP. We unexpectedly discovered their equipment is a single point failure. Their extended outage is an extreme disappointment to us.
We are an extremely small team. The OSMF budget is tiny and we could definitely use more help. Real world experience… Ironically we signed a contract with a new ISP in the last few days. Install is on-going (fibre runs, modules & patching) and we expect to run old and new side-by-side for 6 months. Significantly better resilience (redundant ISP side equipment, VRRP both ways, multiple upstream peers… 2x diverse 10G fibre links).
OpenStreetMap celebrated its 20th anniversary in August, with a TechCrunch profile reminding readers the site gives developers “geographic data and maps so they can rely a little less on the proprietary incumbents in the space,” reports TechCrunch, adding “Yes, that mostly means Google.”
OpenStreetMap starts with “publicly available and donated aerial imagery and maps, sourced from governments and private organizations such as Microsoft” — then makes them better:
Today, OpenStreetMap claims more than 10 million contributors who map out and fine-tune everything from streets and buildings, to rivers, canyons and everything else that constitutes our built and natural environments… Contributors can manually add and edit data through OpenStreetMap’s editing tools, and they can even venture out into the wild and map a whole new area by themselves using GPS, which is useful if a new street crops up, for example…
OpenStreetMap’s Open Database License allows any third-party to use its data with the appropriate attribution (though this attribution doesn’t always happen). This includes big-name corporations such as Apple and VC-backed unicorns like MapBox, through a who’s who of tech companies, including Uber and Strava… More recently, the Overture Maps Foundation — an initiative backed by Microsoft, Amazon, Meta and TomTom — has leaned heavily on OpenStreetMap data as part of its own efforts to build a viable alternative to Google’s walled mapping garden.
The article notes that OpenStreetMap is now overseen by the U.K.-based nonprofit OpenStreetMap Foundation (supported mainly by donations and memberships), with just one employee — a system engineer — “and a handful of contractors who provide administrative and accounting support.”
In August its original founder Steve Coast, returned to the site for a special blog post on its 20th anniversary:
OpenStreetMap has grown exponentially or quadratically over the last twenty years depending on the metric you’re interested in… The story isn’t so much about the data and technology, and it never was. It’s the people… OpenStreetMap managed to map the world and give the data away for free for almost no money at all. It managed to sidestep almost all the problems that Wikipedia has by virtue of only representing facts not opinions. The project itself is remarkable. And it’s wonderful that so many are in love with it.
“Two decades ago, I knew that a wiki map of the world would work,” Coast writes. “It seemed obvious in light of the success of Wikipedia and Linux…”
