Scientists make revolutionary breakthrough that could transform energy storage: 'Truly a game-changer'
"AI is an important tool that can facilitate the advancement of science," Esther Takeuchi, chair of the Interdisciplinary Science Department at Brookhaven Lab and William and Jane Knapp Chair in Energy and the Environment at Stony Brook University, told Tech Xplore. "The research done by this team provides an example of the insights that can be gained by combining experiment and theory enhanced by the use of AI."
In their study, published in PRX Energy, researchers were trying to understand why zinc-ion batteries run better when filled with a super-salty solution. To find out, they trained an AI model to simulate what happens inside the battery at an atomic level—something a standard computer would've needed years to do.
"This work demonstrates the great impact artificial intelligence and machine learning can have for understanding the chemistry of materials and provides guidelines for optimizing battery electrolytes," lead researcher Deyu Lu told Tech Xplore.
Turns out, the salt (zinc chloride) keeps water molecules from splitting apart into hydrogen gas, a common problem that usually wrecks performance. In this setup, the water molecules stop clinging to each other. That stabilizes the battery and keeps it running as intended.
The high salt concentration also helps zinc ions move more easily between battery parts. That cuts down on energy waste and delays.
Zinc-ion batteries are cheaper and less toxic to make than lithium ones. They're nonflammable, run on widely available materials, and could be a better option for storing energy from solar panels or other affordable sources, especially during outages or times of high demand. Solar installation companies such as EnergySage may soon offer such products.
While this tech won't replace lithium overnight, it could soon show up in grid storage and emergency systems. This means there will be less need for pollutant sources like gas and coal, and cleaner air for the people breathing it.
AI helped speed things up, but it's not all upside. Models like this require a ton of computing power. Some of them burn through electricity and water faster than you'd think. Training just one large model can produce as much pollution as five gas-powered cars do over their lifetimes.
Still, used carefully, tools like this could help solve real problems. If zinc batteries become easier to make and store, clean energy becomes easier to use. That's a win worth paying attention to.
"AI/ML is truly a game-changer in the study of complex materials," Lu told Tech Xplore.

Stock market today: S&P 500, Nasdaq on pace for new records as earnings roll in
US stocks were on pace to notch new record highs on Thursday as Wall Street filtered through a fresh wave of earnings while keeping an eye on President Trump's campaign to push out Federal Reserve Chair Jerome Powell. The Dow Jones Industrial Average (^DJI) rose 0.4% while the S&P 500 (^GSPC) also gained about 0.5%. The tech-heavy Nasdaq Composite (^IXIC) climbed 0.8% on the heels of another record-setting session for tech stocks. The S&P 500 and Nasdaq were poised to close at fresh all-time highs as investors navigate a plethora of catalysts, including earnings, economic data, Trump's tariffs, and the president's displeasure with the Fed's stance on interest rates. Retail sales rebounded in June, an indication that Trump's tariffs are not significantly impacting consumer spending habits yet. The reading serves as another snapshot of the health of the US consumer, who big banks so far this earnings season say seem to be doing just "fine." Also out Thursday morning, data from the Department of Labor showed 221,000 initial jobless claims were filed in the week ending July 12. After picking up in May, weekly filings for unemployment claims are now at their lowest level in three months. In earnings, TSMC (TSM) posted a record quarterly profit early on Thursday, citing stronger and stronger AI demand. The Nvidia supplier's shares popped as its results boosted other chipmaker stocks. Meanwhile, PepsiCo (PEP) reported a surprise rise in revenue and lowered its forecast drop in 2025 profit. Read more: Full earnings coverage in our live blog But Netflix (NFLX) is the highlight of Thursday's docket, as it kicks off this season's Big Tech earnings reports with results due after the bell. The streaming giant's shares are on a tear so far this year. On the back burner for now are Trump's renewed threats to attempt to fire Powell, which sparked a stock sell-off at one point on Wednesday. While the president said he was "not planning" to do so, he has spent months excoriating Powell and the Fed's lack of appetite for interest rate cuts. Investor bets suggest Trump is likely to remain disappointed after the central bank's meeting in two weeks, as nearly 100% of traders expect a rate hold amid mixed signals on inflation. Meanwhile, the dollar (DX=F) continued to climb out of the trough it fell into as the prospect of Powell's removal rattled markets. Read more: The latest on Trump's tariffs Crypto watchers eye possible vote on legislation in House Crypto investors were watching developments in Congress on Thursday as lawmakers debated key bills, including legislation that would create guardrails surrounding stablecoins, tokens backed by assets such as the US dollar. Shares of stablecoin issuer Circle (CRCL) rose during the session as the Genius Act was likely to be voted on during the afternoon session. Meanwhile, the Clarity Act, a regulatory framework for payment stablecoins and digital assets, was also up for debate. "This is a moment in time when the stars are aligned to pass these bills," said Pat Daugherty of Foley & Lardner, who contributed draft comments on early versions of the Genius and Clarity bills. Meanwhile bitcoin (BTC-USD), which touched all-time highs this week on increased inflows into spot ETFS and bullish momentum as the House debated crypto legislation, was little changed on Thursday.

In June, the US surprisingly added 147,000 jobs, more than the 106,000 expected by economists, while the unemployment rate ticked down to 4.1%. Investors have maintained their bets on Federal Reserve interest-rate cuts. As of Thursday morning, traders were pricing in a 54% chance the central bank cuts interest rates by its September meeting, down from a roughly 70% chance seen just last week, according to the CME FedWatch Tool.

Pepsi stock rises on better-than-expected earnings PepsiCo (PEP) stock rose 2% after the company reported better-than-expected quarterly results. Pepsi still expects a drop in annual profit, though not as severe as it expected previously. It sees its full-year core earnings per share falling 1.5% instead of the 3% previously forecast. The Gatorade and Lay's maker benefited from favorable foreign exchange rates and greater demand for energy drinks and healthier soda brands, like its prebiotic soda brand Poppi.

TSMC stock pops 3% on record quarterly earnings Taiwan Semiconductor Manufacturing Company (TSM) posted a record quarterly profit on Thursday, sending the stock 3% higher in premarket trading. The company reported net profit of 398.3 billion new Taiwan dollars ($13.5 billion), an increase of more than 60% year over year. TSMC, which is Nvidia's (NVDA) primary chip manufacturer, said that artificial intelligence demand was growing and raised its sales outlook for the third quarter and full year. In a policy reversal, Nvidia has been allowed to resume sales of its H20 chip in China, which could help it recoup as much as $15 billion in revenue. Nvidia shares were up half a percent on Thursday morning. "China is a big market, and my customer can continue to supply the chip to the big market," TSMC CEO C.C. Wei said at a press conference. "It's very positive news for them, and in return, it's very positive news for TSMC." While TSMC has not seen changes in customers' behavior so far, it cautioned that tariffs could affect income in the fourth quarter.

Opendoor stock explodes higher as retail piles in, hedge funder sees potential 100x rally in 'next few years'
Opendoor Technologies (OPEN) stock has exploded higher in recent weeks, rising more than 11% on Wednesday to bring its one-month gains to nearly 200%. Retail enthusiasm and a thesis from investor Eric Jackson have powered a surge in the long-dormant housing play. Opendoor, the leader in iBuyer real estate technology, went public via a SPAC in December 2020. The stock reached an all-time high closing high of $39.24 on Feb. 11, 2021. Within two years, shares were under $1. Jackson, the president and founder of tech-focused long/short investing hedge fund EMJ Capital who was also early to call for a turnaround at Carvana (CVNA), posted a thread to X on July 14 outlining his Opendoor thesis, citing several tailwinds and concluding that "we believe it could be a 100-bagger over the next few years." The stock has roughly doubled since those comments. Read more about Opendoor's stock moves and today's market action. "I think it just shows how mispriced the stock has been over the last, I don't know, year and a bit," Jackson told Yahoo Finance on Thursday. "The valuation was so off that if people did start to change their opinions, this thing could move a lot, not just double or triple or quadruple." And retail traders seem to have piled into the trade since Jackson made his views public. In the past 24 hours, at least a dozen posts citing bullish options plays on Opendoor were posted to the r/WallStreetBets Reddit page, a hub for speculative derivatives trading, that have cumulatively garnered more than 2,000 comments. Part of Jackson's thesis is that the company faces no true competition now that Zillow and Redfin have exited the iBuyer game. iBuyer technology uses algorithms to help companies buy homes from owners for cash, make light repairs, then flip them back onto the open market to hopefully resell at a profit. The strategy once had buy-in from some of the real estate industry's biggest names, but real estate giants Zillow (Z) and Redfin announced in 2021 and 2022, respectively, that they were getting out of the iBuyer space and returning to their core offerings. To Jackson, this makes Opendoor similar to a bet on Coinbase (COIN) before the collapse of FTX. Read more: Is it a good time to buy a house? "You had to make a bet on 'is crypto truly dead?' in the way that probably the majority of people were thinking at the time, or, if it does come back, how is that going to play out with Coinbase being one of the only national names in town," Jackson said. FTX went under in December 2022. Coinbase stock closed at around $34 in early 2023. Today, Coinbase shares trade north of $400. When Opendoor reports earnings on Aug. 5, Jackson predicts the company will show its first quarter of positive EBITDA. He also agrees with analyst consensus estimates that Opendoor is likely to print revenue of $11.6 billion in FY 2029. In fiscal 2024, Opendoor's revenue tallied $5.2 billion. Offerpad Solutions (OPAD), often cited as Opendoor's biggest competitor in the iBuyer space, has also seen its shares surge recently. However, Jackson told Yahoo Finance that Offerpad lacks the scale to compete nationally in the long term with Opendoor. Instead, he sees Opendoor as likely to be the dominant player in iBuying over the long run. "Everybody is a prisoner of the moment and just thinks like market rates are going to be high forever, the housing market is going to suck forever," Jackson said. "Things change, market rates drop, suddenly there is a frenzy of buying — and if those macro things happen, Opendoor is in a perfect position for it," he added.

L3Harris unveils new long-range missile with eye on China in the Pacific
By Mike Stone WASHINGTON (Reuters) -L3Harris Technologies has unveiled two new missiles that aim to provide less expensive long-range strike options for the U.S. military as it restocks its supplies while looking for arms to deter China's ambitions in the Pacific. The "Red Wolf" and "Green Wolf" missile launch comes as the concept of "affordable mass" has gained prominence due to the conflicts in Ukraine and Israel, which have underscored the need for plentiful, cost-effective weapons. This strategy focuses on having a large number of relatively inexpensive munitions ready for deployment, ensuring military readiness and adaptability. These multi-role missiles with a range of more than 200 nautical miles can hit moving targets like ships, such as in the Pacific Ocean where range is important. Lockheed Martin and RTX currently dominate the space in the U.S. market. The most basic version of L3's new missile would cost in the $300,000-range once production has reached full rate, L3 executives told Reuters in an interview. Currently, the low-rate initial production run is being generated in Ashburn, Virginia, with the customers like the Pentagon eyeing buying about 1,000 per year, L3 executives said. The Red Wolf is a traditional missile focused on long-range precision strikes, while the Green Wolf specializes in electronic warfare, equipped with capabilities for electronic attack and intelligence gathering. L3Harris has conducted over 40 successful test flights, demonstrating the reliability and effectiveness of these systems. 擷取數據時發生錯誤 登入存取你的投資組合 擷取數據時發生錯誤 擷取數據時發生錯誤 擷取數據時發生錯誤 擷取數據時發生錯誤
