Scientists Pinpoint Cause of Morning Sickness To Hormone Made By Fetus

Slashdot - Fri, 2023-12-15 10:00
Scientists have pinpointed the cause of nausea and vomiting in pregnancy, "finding that the severity of illness is influenced by how much of a hormone called GDF15 the growing fetus makes," reports Science Magazine. The findings have been published in the journal Nature. From the report: GDF15 is present in the blood of nonpregnant people and is known to be associated with nausea; it's also been tested as a weight loss aid because of its tendency to suppress appetite. Levels of the hormone rise sharply in early pregnancy and increase throughout gestation. Pregnant people with higher GDF15 concentrations have been documented as having a higher risk of vomiting and nausea. Some researchers suggest the hormone-caused aversion to some smells and tastes might encourage an expectant parent to avoid foods potentially dangerous to the fetus. To find out more about GDF15 changes during pregnancy, University of Cambridge physician-scientist Stephen O'Rahilly and colleagues studied half a dozen pregnant people who were known from previous genetic screening to produce a slightly different version of the GDF15 protein from their fetuses. Researchers could take advantage of that difference to trace whether GDF15 in the parent's blood originated in the parental or fetal genome: Almost all of it came from the fetus, O'Rahilly says. The team also took a closer look at the link between GDF15 levels and pregnancy sickness. Consistent with previous research, questionnaires from more than 300 participants showed that people who reported vomiting and nausea had significantly higher levels of circulating GDF15 on average than people without these symptoms. The researchers also found elevated levels of GDF15 in an analysis of more than 50 women hospitalized with hyperemesis gravidarum. Still, hormone levels alone couldn't explain the difference in sickness severity. "There was a big overlap" in GDF15 levels between the groups, O'Rahilly says. He and co-author Marlena Fejzo, a researcher at the University of Southern California, suspected that people's sensitivity to GDF15 might also play a role. (Fejzo began to study the condition after her own pregnancy loss following hyperemesis gravidarum.) To test the idea, the researchers studied 10 nonpregnant people with a rare genetic variant known to carry a heightened risk of hyperemesis gravidarum. These people had reduced GDF15 levels in their blood, hinting that naturally low levels of the hormone might predispose someone to sickness during pregnancy. The researchers found the opposite when they asked 20 pregnant people with beta thalassemia, a blood disorder associated with high GDF15 levels, about their pregnancy symptoms: Just 5% of this group reported nausea or vomiting. O'Rahilly's lab found a similar pattern in animal experiments.

NASA's Voyager 1 Probe In Interstellar Space Can't Phone Home

Slashdot - Fri, 2023-12-15 07:00
NASA's Voyager 1 spacecraft is, once again, having trouble transmitting any scientific or systems data back to Earth. "The 46-year-old spacecraft is capable of receiving commands, but a problem seems to have arisen with the probe's computers," reports Space.com. Slashdot readers quonset and ArchieBunker shared the news. From the report: Voyager 1's flight data system (FDS), which collects onboard engineering information and data from the spacecraft's scientific instruments, is no longer communicating as expected with the probe's telecommunications unit (TMU), according to a NASA blog post on Dec. 12. When functioning properly, the FDS compiles the spacecraft's info into a data package, which is then transmitted back to Earth using the TMU. Lately, that data package has been "stuck," the blog post said, "transmitting a repeating pattern of ones and zeros." Voyager's engineering team traced the problem back to the FDS, but it could be weeks before a solution is found. In May 2022, Voyager 1 experienced transmitting issues for several months before a workaround was found. Meanwhile, Voyager 2 experienced an unplanned "communications pause" earlier this year after a routine sequence of commands triggered a 2-degree change in the spacecraft's antenna orientation. This prevented it from receiving commands or transmitting data back to Earth until NASA fixed the issue a week later.

Google DeepMind Uses LLM To Solve Unsolvable Math Problem

Slashdot - Fri, 2023-12-15 03:30
An anonymous reader quotes a report from MIT Technology Review: In a paper published in Nature today, the researchers say it is the first time a large language model has been used to discover a solution to a long-standing scientific puzzle -- producing verifiable and valuable new information that did not previously exist. "It's not in the training data -- it wasn't even known," says coauthor Pushmeet Kohli, vice president of research at Google DeepMind. Large language models have a reputation for making things up, not for providing new facts. Google DeepMind's new tool, called FunSearch, could change that. It shows that they can indeed make discoveries -- if they are coaxed just so, and if you throw out the majority of what they come up with. FunSearch (so called because it searches for mathematical functions, not because it's fun) continues a streak of discoveries in fundamental math and computer science that DeepMind has made using AI. First Alpha Tensor found a way to speed up a calculation at the heart of many different kinds of code, beating a 50-year record. Then AlphaDev found ways to make key algorithms used trillions of times a day run faster. Yet those tools did not use large language models. Built on top of DeepMind's game-playing AI AlphaZero, both solved math problems by treating them as if they were puzzles in Go or chess. The trouble is that they are stuck in their lanes, says Bernardino Romera-Paredes, a researcher at the company who worked on both AlphaTensor and FunSearch: "AlphaTensor is great at matrix multiplication, but basically nothing else." FunSearch takes a different tack. It combines a large language model called Codey, a version of Google's PaLM 2 that isfine-tuned on computer code, with other systems that reject incorrect or nonsensical answers and plug good ones back in. The researchers started by sketching out the problem they wanted to solve in Python, a popular programming language. But they left out the lines in the program that would specify how to solve it. That is where FunSearch comes in. It gets Codey to fill in the blanks -- in effect, to suggest code that will solve the problem. A second algorithm then checks and scores what Codey comes up with. The best suggestions -- even if not yet correct -- are saved and given back to Codey, which tries to complete the program again. After a couple of million suggestions and a few dozen repetitions of the overall process -- which took a few days -- FunSearch was able to come up with code that produced a correct and previously unknown solution to the cap set problem, which involves finding the largest size of a certain type of set. Imagine plotting dots on graph paper. [...] To test its versatility, the researchers used FunSearch to approach another hard problem in math: the bin packing problem, which involves trying to pack items into as few bins as possible. This is important for a range of applications in computer science, from data center management to e-commerce. FunSearch came up with a way to solve it that's faster than human-devised ones.

Google Releases On-Device Diagnostics Tool, Repair Manuals For Pixel Phones

Slashdot - Fri, 2023-12-15 01:25
Emma Roth reports via The Verge: Google is releasing a tool to help users diagnose problems with their Pixel phones. Users can launch the app by entering #*#7287#*# on the dial pad, allowing them to check whether their phone is working correctly before or after a repair. There are a bunch of diagnostic tools available within the app. While users can run a full diagnostic test to detect issues across the entire device, there are also options to run individual tests for physical defects and problems affecting the phone's display, sensors, and connectivity. The new tool is available on all Pixel phones in English. Aside from the diagnostics app, Google is introducing redesigned repair manuals the company says are "easier for technicians and DIYers to use." Users can download repair manuals from Google's website in English and French, but they're only available for the Pixel Fold, Pixel 8, and Pixel 8 Pro for now. Google says it will add repair manuals for previous and future devices "in the coming months." There's also a new Repair Mode Google introduced earlier this month, which Pixel Phone owners can toggle on when their device is getting repaired. The feature is meant to protect users' private information while their phone is in the hands of a technician [...].

Cheating Fears Over Chatbots Were Overblown, New Research Suggests

Slashdot - Fri, 2023-12-15 00:45
Natasha Singer reports via The New York Times: According to new research from Stanford University, the popularization of A.I. chatbots has not boosted overall cheating rates in schools (Warning: source may be paywalled; alternative source). In surveys this year of more than 40 U.S. high schools, some 60 to 70 percent of students said they had recently engaged in cheating -- about the same percent as in previous years, Stanford education researchers said. "There was a panic that these A.I. models will allow a whole new way of doing something that could be construed as cheating," said Denise Pope, a senior lecturer at Stanford Graduate School of Education who has surveyed high school students for more than a decade through an education nonprofit she co-founded. But "we're just not seeing the change in the data." ChatGPT, developed by OpenAI in San Francisco, began to capture the public imagination late last year with its ability to fabricate human-sounding essays and emails. Almost immediately, classroom technology boosters started promising that A.I. tools like ChatGPT would revolutionize education. And critics began warning that such tools -- which liberally make stuff up -- would enable widespread cheating, and amplify misinformation, in schools. Now the Stanford research, along with a recent report from the Pew Research Center, are challenging the notion that A.I. chatbots are upending public schools.

Alphabet's 'Renew Home' Company Brings Power Grid Data To Your Smart Home

Slashdot - Fri, 2023-12-15 00:02
An anonymous reader quotes a report from Ars Technica: Google's parent company, Alphabet, is launching a new company called "Renew Home." The new company will pull in some other projects from Nest and the rest of Alphabet to become a supposed one-stop shop for power savings and clean energy usage. The core concept is partnering with power companies to obtain data about the current condition of the power grid and using that data to change consumer habits. The new company is bankrolled by Sidewalk Infrastructure Partners (SIP), an Alphabet venture capital firm. The first existing service getting pulled into Renew Home is Nest Renew. This service for Nest Thermostats uses power company data to tell consumers how their electricity is being generated and what it costs. That data lets your thermostat do things like automatically shift heating and cooling to times of day when energy is cheaper or cleaner, and shows various reports about the cleanness of the energy you've been using. (Nest's feature that lets utility companies remotely take control of your thermostat, Rush Hour Rewards, does not seem to be part of Renew Home.) Another Alphabet service being pulled into Renew Home is OhmConnect, which is the same basic idea as Nest's grid data-power thermostat adjustments but for more than just your thermostat. OhmConnect is compatible with a very small list of smart devices, like Nest-rival Ecobee and Honeywell thermostats, TL-Link's "Kasa" smart home system, and Tesla vehicles. The backbone of the service appears to be the in-house "OhmPlug" smart outlet, which can monitor the energy usage of anything that plugs into the wall. By seeing that you've turned these smart devices during peak usage times, OhmConnect offers people rewards like gift cards or cash for not using power when the grid is at capacity.

Proton Mail Finally Gets a Desktop App For Encrypted Email and Calendar

Slashdot - Thu, 2023-12-14 23:20
Amrita Khalid reports via The Verge: Proton has released a desktop version of its Proton Mail app that will give users full access to both Proton Mail and Proton Calendar and (eventually) the ability to view your emails offline. The desktop app is available in beta is optimized for both Windows and macOS, and encrypts sent emails end-to-end just like with the browser version, according to the Swiss company, while offline access to emails will be available "soon." [...] It's important to note that you'll still need internet access to both send and encrypt your emails on Proton. But the offline feature will let you view and draft emails while traveling, during a power outage, or any other situation where you don't have access to the internet. Proton is also bringing encrypted auto-forwarding to paid users, both on its desktop and browser versions, though the encryption for forwards will only apply when the forwarded emails go to other Proton users. The company says it has made improvements to Proton Calendar, too, including a fully searchable web version. Not everyone will be able to access Proton's desktop app right away. Proton is restricting access to its paid "Visionary" tier for legacy users at first (though the company is reopening subscriptions to that tier through January 3rd, 2024). The plan is to make the desktop app available to all users in early 2024.

Threads Launches In the European Union

Slashdot - Thu, 2023-12-14 22:40
Meta CEO Mark Zuckerberg announced that Threads is now available to users in the European Union. "Today we're opening Threads to more countries in Europe," wrote Zuckerberg in a post on the platform. "Welcome everyone." MacRumors reports: The move comes five months after the social media network launched in most markets around the world, but remained unavailable to EU-based users due to regulatory hurdles. [...] In addition to creating a Threads profile for posting, users in the EU can also simply browse Threads without having an Instagram account, an option likely introduced to comply with legislation surrounding online services. The expansion into a market of 448 million people should see Threads' user numbers get a decent boost. Meta CEO Mark Zuckerberg said on a company earnings call in October that Threads now has "just under" 100 million monthly users. Since its launch earlier this year it has gained a web app, an ability to search for posts, and a post editing feature.

Supply Chain Attack Targeting Ledger Crypto Wallet Leaves Users Hacked

Slashdot - Thu, 2023-12-14 22:00
An anonymous reader quotes a report from TechCrunch: Hackers compromised the code behind a crypto protocol used by multiple web3 applications and services, the software maker Ledger said on Thursday. Ledger, a company that makes a widely used and popular crypto hardware and software wallet, among other products, announced on X (previously Twitter) that someone had pushed out a "malicious version" of its Ledger Connect Kit, a library that decentralized apps (dApps) made by other companies and projects use to connect to the Ledger wallet service. "A genuine version is being pushed to replace the malicious file now. Do not interact with any dApps for the moment. We will keep you informed as the situation evolves," Ledger wrote. Soon after, Ledger posted an update saying that the hackers had replaced the genuine version of its software some six hours earlier, and that the company was investigating the incident and would "provide a comprehensive report as soon as it's ready." After this story was published, Ledger spokesperson Phillip Costigan shared more details about the hack with TechCrunch and on X. Costigan said that a former Ledger employee was victim of a phishing attack on Thursday, which gave the hackers access to their former employee's NPMJS account, which is a software registry that was acquired by GitHub. From there, the hackers published a malicious version of the Ledger Connect Kit. "The malicious code used a rogue WalletConnect project to reroute funds to a hacker wallet," Costigan said. Then, Ledger deployed a fix within 40 minutes of the company becoming aware of the hack. The malicious file, however, was live for round 5 hours, but "the window where funds were drained was limited to a period of less than two hours," according to Costigan. Ledger also "coordinated" with WalletConnect which "quickly disabled the the rogue project," essentially stopping the attack, according to Costigan. Costigan also said Ledger pushed out a genuine software update that is "safe to use." "We are actively talking with customers whose funds might have been affected, and working proactively to help those individuals at this time," the Ledger spokeperson said, adding that the company believes it has identified the hackers' wallet.
