Biden’s Contraceptive Mandate Reversal Victory for Nuns

27th December 2024

Read it.

“Christmas came early” for the Little Sisters of the Poor earlier this week when the Biden administration dropped its controversial contraceptive healthcare mandate, ostensibly ending the nuns’ 14-year battle over religious liberty with the federal government, the Catholic News Agency reported.

The Department of Health and Human Services on Monday announced its decision to leave in place Trump-era guidelines that allow employers to opt out of birth control coverage over religious or moral objections. The move let stand an existing rule that permits employers to cite “non-religious moral objections” to the Affordable Care Act’s requirement to cover contraception.

When Obama said, “If you like your coverage, you can keep your coverage.”, what made that a lie was the fact that, under Obamacare, it didn’t matter how much you liked your coverage — you were going to get the coverage that the government decided you ought to have, whether you could afford it or not.

In something of a stunning development, China appears to already be flying a stealthy, high-performance, flying-wing, sixth-generation crewed combat aircraft, imagery of which began to emerge today. At this early stage, we have very little idea about the precise identity of the new aircraft, but many elements of its design are very much in line with what we already knew about Chinese sixth-generation airpower aspirations.

Scientists Destroy 99% of Cancer Cells in Lab Using Vibrating Molecules

25th December 2024

Read it.

Scientists have discovered a remarkable way to destroy cancer cells. A study published last year found stimulating aminocyanine molecules with near-infrared light caused them to vibrate in sync, enough to break apart the membranes of cancer cells.

Aminocyanine molecules are already used in bioimaging as synthetic dyes. Commonly used in low doses to detect cancer, they stay stable in water and are very good at attaching themselves to the outside of cells.

The research team from Rice University, Texas A&M University, and the University of Texas, said their approach is a marked improvement over another kind of cancer-killing molecular machine previously developed, called Feringa-type motors, which could also break the structures of problematic cells.

“It is a whole new generation of molecular machines that we call molecular jackhammers,” said chemist James Tour from Rice University, when the results were published in December 2023.

“They are more than one million times faster in their mechanical motion than the former Feringa-type motors, and they can be activated with near-infrared light rather than visible light.”

The Architects of Life: Scientists Decipher mRNA’s Secret Blueprint

23rd December 2024

Read it.

Researchers discovered that the mRNA modification m6A triggers rapid degradation, regulating protein production. This breakthrough could inform drug development to manage protein-related diseases.

Messenger ribonucleic acids (mRNA) are like the architects of our bodies. They carry precise blueprints for building proteins, which are read and assembled by their cellular partners, the ribosomes. Proteins are essential for our survival, as they regulate cell division, bolster the immune system, and make our cells resilient against external threats.

Just like in real-world construction, some cellular blueprints require extra instructions—such as when a protein needs to be produced rapidly or when corrections are needed for a flawed design. In our bodies, this role is fulfilled by RNA modifications. These small chemical changes function like detailed annotations, offering additional guidance to specific parts of the mRNA for optimal protein production.

This was always part of the “invisible man” strategy. Progressive love creating an invisible man to do the dirty work so they can pretend to be observers, commenting upon the natural flow of history. “Some people say you are a polarizing figure” always turns up in whenever a normal person agrees to talk to a crazy from regime media.
Musk buying Twitter has had the unintended effect of buggering up the mechanism these people used to manufacture their invisible men. Not only can they no longer game the algo to artificially get their stuff trending, but many of the crazies also have either quit the game or shuffled off to Bluesky, which has become an isolate echo chamber.

Starlink Connectivity on iPhone Is Almost Here, Beta Registration Now Open

22nd December 2024

Read it.

Earlier this week, T-Mobile announced that you can now register to beta test Starlink connectivity on your mobile phone, with actual testing expected to begin early next year – roughly two years after the initial announcement.

Back in 2022, T-Mobile and SpaceX announced a partnership to allow T-Mobile customers to utilize Starlink satellites – in an effort to eliminate deadzones for customers. This required SpaceX to design new direct-to-cell satellites, but according to T-Mobile, there are now more than 300 of them in orbit.

In the press release, T-Mobile announced that these new Starlink satellites will cover more than 500,000 square miles of land that aren’t currently served by cell towers. SpaceX will also continue to launch more of these direct-to-cell satellites over time, though a timeline wasn’t provided for when there’ll be a non-beta rollout.

During the beta, you’ll be able to send text messages – with voice and data support coming later.

Britannica Didn’t Just Survive. It’s an A.I. Company Now.

22nd December 2024

New York Times.

For nearly 250 years, the Encyclopaedia Britannica was a bookshelf-busting series of gilt-lettered tomes, often purchased to show that its owners cared about knowledge.

It was the sort of physical media expected to die in the internet era, and indeed, the encyclopedia’s publisher announced that it was ending the print edition in 2012. Skeptics wondered how Britannica the company could survive in the age of Wikipedia.

The answer was to adapt to the times.

Britannica Group, as the company is now known, runs websites, including Britannica.com and the online Merriam-Webster dictionary, and sells educational software to schools and libraries. It also sells artificial intelligence agent software that underpins applications like customer service chatbots and data retrieval.

Britannica has figured out not only how to survive, but also how to do well financially. Jorge Cauz, its chief executive, said in an interview that the publisher enjoyed pro forma profit margins of about 45 percent.

Game-Changing Dual Cancer Therapy Completely Eradicates Tumors Without Harsh Side Effects

22nd December 2024

Read it.

Combining phototherapy with chemotherapy may provide a more powerful approach to combat aggressive tumors effectively.

Patients with late-stage cancer often have to endure multiple rounds of different types of treatment, which can cause unwanted side effects and may not always help.

In hopes of expanding the treatment options for those patients, MIT researchers have designed tiny particles that can be implanted at a tumor site, where they deliver two types of therapy: heat and chemotherapy.

This approach could avoid the side effects that often occur when chemotherapy is given intravenously, and the synergistic effect of the two therapies may extend the patient’s lifespan longer than giving one treatment at a time. In a study of mice, the researchers showed that this therapy completely eliminated tumors in most of the animals and significantly prolonged their survival.

Ukrainian M1 Abrams Commander Talks Tank’s Major Vulnerabilities, Advantages in Combat

21st December 2024

Read it. And watch the video.

Last week, several Russian first-person view (FPV) drones struck a U.S.-made M1A1 Abrams tank in the Kursk region, but the crew was able to survive. The vehicle’s commander lauded the American armor for saving their lives, but also highlighted some major vulnerabilities it has on today’s drone-drenched battlefield. In particular he offered important insights on how Ukraine is adapting its M1s to survive — lessons that could prove very valuable for the U.S. Army in future conflicts.

…

“Well, we got a luxurious shooting practice (around 100 rounds fired by each gunner) and some good overall knowledge about the tank,” he explained. “But the American instructors AND military were completely unaware of the modern battlefield threats. And still are unaware (I communicate with some of the American tankers and try to share information with them).”

Poland Adopts Law to Suspend Right to Asylum

19th December 2024

The sleeper wakes.

The Polish government of Donald Tusk has adopted a draft law that would allow the country to temporarily suspend the right to claim asylum. The prime minister said the right to asylum “is being used today—especially on the border with Belarus—by Poland’s enemies,” and that by adopting the bill “we are taking back control of Poland’s borders.”

The bill has been in the works for a while, and is intended as a response to actions of neighbouring Belarus: the country has been flying in migrants from the Middle East and Africa in recent years, and sending them to the borders of the EU—Poland, Latvia, and Lithuania—in a bid to destabilise the region. Those three EU member states have accused Russia of complicity.

The number of migrants arriving at the borders of EU member states from Belarus has increased by 66% this year, compared with 2023. In Poland, 28,000 attempted illegal crossings were recorded by the end of October. The EU says 90% of migrants illegally crossing the Poland-Belarus border have a Russian student or tourist visa.

Shape-Shifting Antenna Takes Cue From “The Expanse”

17th December 2024

Read it.

An antenna’s shape determines what kind of signals it can work with. So key aspects of its operations are in fact already locked in at manufacturing. However, a new shape-shifting antenna could dynamically adapt to different communications requirements allowing it to do the work of multiple fixed antennas.

The new design is the brainchild of a multidisciplinary team at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and was made possible by cutting-edge 3D printing techniques. The antenna features a double spiral made of “shape-memory alloy,” which changes shape when heated or cooled, and can operate effectively at frequencies ranging from 4-11 gigahertz.

‘Conan the Bacterium’ Can Withstand Radiation That Could Kill a Human. Scientists Say They’ve Found Its Secret Weapon

17th December 2024

Read it.

A type of bacteria called Deinococcus radiodurans, nicknamed “Conan the Bacterium” for its ability to survive the harshest of extremes, can withstand radiation doses 28,000 times greater than those that would kill a human being — and the secret to its success is rooted in an antioxidant.

Now, scientists have uncovered how the antioxidant works, unlocking the possibility that it could be used to protect the health of humans, both on Earth and those exploring beyond it in the future.

The antioxidant is formed by a simple group of small molecules called metabolites, including manganese, phosphate and a small peptide, or molecule, of amino acids.

Ah, but can it speak with an Austrian accent?

The Sweet Raspberry Taste of Success Masks a Missed Opportunity

The Register.

The Raspberry Pi is a moral hazard because it’s been far too good to us. For the past 12 years, the Pi series has bombarded the world with extremely affordable, extremely useful computers designed purely to promote education, innovation and the democratization of digital skills.

The full spectrum of geekery, from precocious prepubescents to CEOs of specialist technical companies, has grown to expect an endless stream of well-engineered hardware backed by a mainstream software stack and a thriving ecosystem. From the $4 Pi Pico microcontroller to the new $90 Pi 500 complete desktop computer, Raspberry is what an Apple run by Steve Woz instead of Jobs might have looked like.

As a result, we Pi fans have been spoiled rotten. We don’t see the profound challenge of mastering cheap, powerful and manufacturable at scale – the impossible triangle that sank most of the UK’s first generation of computer makers. We complain when consumers can’t get boards during supply chain meltdown because of the insane success of the Pi in commercial use.

The Underrated Juice That Can Lower Blood Sugar, Burn Fat, and Prevent Illness All at Once

For millennia, elderberry juice played a role in homegrown medicinal treatments. As it turns out, there may be merit to the use of the juice as a therapeutic beverage that can help lower blood sugar, make weight management easier, and increase a person’s immune system.

In a 2024 trial (via Nutrients), participants were asked to drink elderberry juice for one week. Afterward, their fecal matter was examined to identify any positive gut microbiome changes. Researchers found that the participants’ blood glucose levels had dropped by 24%, potentially because of flavonoids found in elderberry juice called anthocyanins. “This is the first human clinical trial to demonstrate that daily consumption of EBJ [elderberry juice] for one week significantly increases gut microbial communities associated with health benefits for the host,” according to Christy Teets, a scientific assistant from Washington State University who worked on the project (per Nutraceutical Business Review).

Electrocaloric Material Makes Solid-State Fridge Scalable

12th December 2024

Read it.

Many of today’s refrigerators and air conditioners have a fundamental flaw. Most coolers operate by vapor compression, relying on a fluid to absorb heat and wick it away. Vapor compression tech is cheap and proven, but it’s also inefficient and about as downsizable as a 1950s vacuum-tube computer. Plus, its workhorse fluids—in particular, hydrofluorocarbons (HFCs)—often enter the atmosphere as potent greenhouse gases.

Fortunately, there are a few solid-state alternatives to vapor compression that avoid these problems. More than just cleaning up refrigerators’ acts, the alternatives could create cooling devices in miniature, small enough to fit in a pocket. One such alternative relies on solid materials that change temperature under an electric field: what scientists call the electrostatic effect.

Researchers have now created arguably the most successful demonstration yet of an electrocaloric component. Relying on a ceramic multilayer capacitor, this regenerative heat exchanger (a.k.a. regenerator) features a difference in temperature more than 50 percent greater than any electrocaloric that preceded it.

Thermoelectric Heating Comes in From the Cold

11th December 2024

Read it.

A decade ago, thermoelectric heating—which relies on the thermoelectric effect, in which electrons are pulled from one material to an adjacent material when both are heated—still required toxic or rare materials such as lead and tellurium. Because the thermoelectric effect is reversible, it also opens the door to cooling, with none of the environmental impact of using liquid refrigerants, or requiring industrial waste heat to be recovered as electricity.

However, the thermoelectric effect is so small in most materials and for small temperature differences that its real-world use so far has been mostly in space vehicles and for precisely controlling the temperature of donated organs for transplant. Researchers use a dimensionless quantity called ZT to describe the strength of the thermoelectric effect in any combination of materials. Two decades ago, combinations such as lead and tellurium yielded ZT values of around 1. After ten years, the search for new, more complex, and more effective materials had yielded ZT values of 2. In 2009, thermoelectrics researcher Cronin Vining wrote in Nature Materials that “commercial quantities of materials and/or efficient devices…does not seem imminent.”

But since then, materials scientists have been reporting more and more materials, such as tin selenide, and half a dozen other combinations, that lend themselves well to the thermoelectric effect.

Biden Decision on Weight-Loss Drugs a Push-Back on Progressives

8th December 2024

Read it.

Last week, the Biden administration passed a rule allowing for the government healthcare programs Medicare and Medicaid coverage of a class of weight-loss drugs that promises to help millions of people lose weight and become healthier. This decision by the White House begs the question: Why wait until after the election to pass a popular proposal that will help millions of working-class Americans afford weight-loss drugs they currently cannot afford to purchase themselves?

A lot of the press analysis portrays this White House decision as a shot by President Biden at the incoming Trump administration, forcing the potential new Health and Human Services Secretary, Robert F. Kennedy Jr., who has cast doubt on the benefits of these drugs, to either keep this Biden era provision or take critical medical coverage away from millions of working-class Americans who rely on government subsidized healthcare.

But my clear understanding of the White House decision to cover GLP-1 weight loss and diabetes drugs like Novo Nordisk’s Ozempic/Wegovy and Eli Lilly’s Mounjaro/Zepbound is that this was not a shot at the incoming Trump administration, but rather, a willingness of the president and the vice president to rebuke the progressive wing of the Democratic Party which has vociferously opposed this new policy. Indeed, lawmakers like Sen. Bernie Sanders of Vermont have waged a personal crusade against the makers of these drugs to reduce their profits.

SciTechDaily.

A new study on human brain evolution reveals that modern humans, Neanderthals, and other recent relatives in our evolutionary lineage developed larger brains at a significantly faster rate compared to earlier species.

The study, published in the journal PNAS, overturns long-standing ideas about human brain evolution. Scientists from the University of Reading, the University of Oxford, and Durham University found that brain size increased gradually within each ancient human species rather than through sudden leaps between species.

The team assembled the largest-ever dataset of ancient human fossils spanning 7 million years and used advanced computational and statistical methods to account for gaps in the fossil record. These innovative approaches provided the most comprehensive view yet of how brain size evolved over time.

Haitian Immigrants ‘Self-Deporting’ Ahead of Trump Inauguration

1st December 2024

The Foundry.

According to both CBS News and The Guardian, thousands of Haitian immigrants in the city of Springfield, Ohio, are rushing to Chicago, New York City, and other “sanctuary” locations before Trump is sworn into office and initiates his pledged mass deportation program.

Springfield, a city of less than 60,000, has been crippled ever since the outgoing Biden-Harris administration imported roughly 20,000 Haitian immigrants into the municipality starting in 2021. The city has seen a drastic rise in housing costs and traffic accidents and has been forced to spend hundreds of thousands of dollars annually to accommodate the immigrants, who were granted “temporary protected status” by the Biden-Harris administration.

Many Haitians in Springfield have taken Trump’s promise of mass deportations—to be enacted by his new “border czar,” former Acting Immigration and Customs Enforcement Director and immigration hardliner Tom Homan—seriously. Trump has vowed to terminate the temporary protected status granted to the Haitians, causing many to leave the Ohio city that Trump mentioned during a presidential debate. Popular destinations for the immigrants include Chicago, New York City, Boston, Canada, and even Brazil, where many Haitian migrants had previously been granted temporary asylum before illegally entering the U.S.

Chinese Pebble-Bed Reactor Passes “Meltdown” Test

30th November 2024

Read it.

New testing done at China’s Shidaowan nuclear power plant has confirmed its ability to be naturally cooled down, an industry-first milestone for achieving commercial-scale inherent safety, according to researchers.

The Shidaowan plant, a demonstration high-temperature, gas-cooled reactor with a pebble-bed module (HTR-PM), went into commercial operation last December.

Shidaowan’s twin 100-MW units house tiny uranium capsules encased in graphite shells about the size of billiard balls (dubbed “pebbles”), which make the energy density of the fuel much lower than in a traditional nuclear reactor with fuel rods. In the pebble design, the nuclear fission reaction occurs more slowly than in conventional reactors, but the fuel can withstand higher temperatures for longer and the heat resulting from the fission reaction is dispersed, enabling a passive cooling process.

The reactor doesn’t rely on large volumes of water in the cooling process—instead, a small amount of helium gas, which can withstand much higher temperatures than water, is piped through the system to naturally cool it down. If the reactor starts to get too hot, its components automatically slow down the nuclear reaction and the system cools. This setup makes such a reactor “meltdown proof,” in concept.

The research suggests aging isn’t strictly temporal, not solely about minutes and years passing. Once considered a steady, predictable decline, affecting everything in our bodies, everywhere, all at once, aging is much more haphazard than we once thought, starting in different parts of our bodies at different times, possibly long before we’re even thinking about aging.

It’s also personal, occurring at a unique molecular level inside each of us, and the process may be partially within our control. Once we know how our own organs are aging, we may be able to brake or speed that process by how we live.

Rural Counties in California, Illinois Push to Secede From Blue States to Separate From Liberal-Run Cities After Trump’s Win: ‘So Flipping Excited’

26th November 2024

New York Post.

A movement in a myriad of rural counties across deep blue states such as Illinois and California to split off and form new states appears to be gaining some steam in the wake of the Nov. 5 election.

Conservative residents of the rural regions are taking note of their peers fleeing to lower-taxed and less-regulated red states but they are ready to stay put — pining for a divorce with the urban sectors of their state.

A group dubbed the New Illinois State has drafted a new constitution and championed plans to “Leave Illinois Without Moving.” On Election Day, seven rural counties in Illinois voted to contemplate splitting off from the state.

NASA: Mystery of Life’s Handedness Deepens

24th November 2024

Read it.

The mystery of why life uses molecules with specific orientations has deepened with a NASA-funded discovery that RNA — a key molecule thought to have potentially held the instructions for life before DNA emerged — can favor making the building blocks of proteins in either the left-hand or the right-hand orientation. Resolving this mystery could provide clues to the origin of life. The findings appear in research recently published in Nature Communications.

Proteins are the workhorse molecules of life, used in everything from structures like hair to enzymes (catalysts that speed up or regulate chemical reactions). Just as the 26 letters of the alphabet are arranged in limitless combinations to make words, life uses 20 different amino acid building blocks in a huge variety of arrangements to make millions of different proteins. Some amino acid molecules can be built in two ways, such that mirror-image versions exist, like your hands, and life uses the left-handed variety of these amino acids. Although life based on right-handed amino acids would presumably work fine, the two mirror images are rarely mixed in biology, a characteristic of life called homochirality. It is a mystery to scientists why life chose the left-handed variety over the right-handed one.

Trump’s Republican Party Is Increasingly Winning Union Voters. It’s a Shift Seen in His Labor Pick

24th November 2024

Associated Press.

Working-class voters helped Republicans make steady election gains this year and expanded a coalition that increasingly includes rank-and-file union members, a political shift spotlighting one of President-elect Donald Trump’s latest Cabinet picks: a GOP congresswoman, who has drawn labor support, to be his labor secretary.

Oregon Rep. Lori Chavez-DeRemer narrowly lost her bid for a second term this month, despite strong backing from union members, a key part of the Democratic base but gravitating in the Trump era toward a Republican Party traditionally allied with business interests.

“Lori’s strong support from both the Business and Labor communities will ensure that the Labor Department can unite Americans of all backgrounds behind our Agenda for unprecedented National Success – Making America Richer, Wealthier, Stronger and more Prosperous than ever before!” Trump said in a statement announcing his choice Friday night.

A Camera the Size of a Grain of Salt Could Change Imaging as We Know It

23rd November 2024

Or don’t, as the case may be….

When it comes to cameras, size matters, but not in the way you think.

Any time a new smartphone is released, it is easy to drool over the latest, greatest, and biggest features that allow you to take even more stunning selfies composed of even more megapixels. However, in the world of cameras, smaller cameras could end up having a far greater impact on the world at large—and enable a ton of positive applications in society—than the next iPhone camera. Work from researchers at Princeton University and the University of Washington is pointing the way.

A team of researchers from both institutions has published work that uses innovative methods and materials to create a “meta-optics” camera that is the size of a single grain of salt.

‘Achilles Heel’ of Antibiotic-Resistant Bacteria Discovered in Life-Saving Breakthrough

20th November 2024

Read it.

n the ongoing battle against antibiotic-resistant “superbugs,” researchers have uncovered an unexpected vulnerability that could change how we fight these deadly infections – and it all comes down to a microscopic competition for resources.

The discovery comes at a crucial time. Current estimates paint a grim picture: drug-resistant infections already claim over one million lives annually, with deaths projected to nearly double to two million per year by 2050.

However, a team led by researchers at the University of California-San Diego may have found a new way to tackle this crisis without relying on traditional antibiotics. Their research, published in Science Advances, reveals that antibiotic-resistant bacteria have an inherent weakness – one that might explain why these seemingly unstoppable superbugs haven’t completely taken over.

Ga. Appeals Court Cancels Hearing in Case Against Trump

19th November 2024

Read it.

A Georgia appeals court on Monday canceled oral arguments that were scheduled for next month on the appeal of a lower court ruling allowing Fulton County District Attorney Fani Willis to continue to prosecute the election interference case she brought against President-elect Donald Trump.

Trump and other defendants had asked the Georgia Court of Appeals to hold oral arguments in the case, and the court had set those arguments for Dec. 5. But in a one-line order with no further explanation, the appeals court said that hearing “is hereby canceled until further order of this Court.”

A Fulton County grand jury in August 2023 indicted Trump and 18 others, accusing them of participating in a sprawling scheme to illegally try to overturn the 2020 presidential election in Georgia. Four defendants have pleaded guilty after reaching deals with prosecutors, but Trump and the others have pleaded not guilty.

Egg Consumption and 4-Year Change in Cognitive Function in Older Men and Women: The Rancho Bernardo Study

19th November 2024

Read it.

The effect of dietary cholesterol on cognitive function is debatable. While eggs contain high levels of dietary cholesterol, they provide nutrients beneficial for cognitive function. This study examined the effects of egg consumption on change in cognitive function among 890 ambulatory adults (N = 357 men; N = 533 women) aged ?55 years from the Rancho Bernardo Study who attended clinic visits in 1988–1991 and 1992–1996. Egg intake was obtained in 1988–1991 with a food frequency questionnaire. The Mini-Mental Status Exam (MMSE), Trails B, and category fluency were administered at both visits to assess cognitive performance. Sex-specific multiple regression analyses tested associations of egg intake with changes in cognitive function after adjustment for confounders. The mean time between visits was 4.1 ± 0.5 years; average ages were 70.1 ± 8.4 in men and 71.5 ± 8.8 in women (p = 0.0163). More men consumed eggs at higher levels than women; while 14% of men and 16.5% of women reported never eating eggs, 7.0% of men and 3.8% of women reported intakes ?5/week (p = 0.0013). In women, after adjustment for covariates, egg consumption was associated with less decline in category fluency (beta = ?0.10, p = 0.0241). Other associations were nonsignificant in women, and no associations were found in men. Results suggest that egg consumption has a small beneficial effect on semantic memory in women. The lack of decline observed in both sexes suggests that egg consumption does not have detrimental effects and may even have a role in the maintenance of cognitive function.

Eco-Activists May Have Inadvertently Gutted One of Their Favorite Regulatory Systems

17th November 2024

Read it.

Eco-activists sued the federal government to stop activity they didn’t like, but a bombshell Tuesday ruling in that case from a federal appeals court may end up weakening a regulatory system that has served environmentalists well for years.

The U.S. Court of Appeals for the D.C. Circuit ruled in Marin Audubon Society v. Federal Aviation Authority (FAA) that the White House Council on Environmental Quality (CEQ) does not have the legal authority to issue National Environmental Policy Act (NEPA) rules.

Trump Team Plans To Axe Biden’s EV Tax Credit: Report

14th November 2024

Read it.

President-elect Donald Trump’s transition team is preparing to eliminate the Biden administration’s $7,500 electric vehicle tax credit as part of its broader tax reform plan, Reuters reported Thursday.

Trump’s energy-policy team, led by oil magnate Harold Hamm and North Dakota Gov. Doug Burgum (R.), has held several meetings to discuss repealing the EV subsidy, a cornerstone of President Joe Biden’s Inflation Reduction Act, sources told Reuters.

Trump plans to use savings from ending the tax credit to help fund the extension of his 2017 tax cuts, which are set to expire at the end of 2025, Reuters reported. With the GOP retaining control of the House, congressional Republicans plan to make broader tax reform a top priority.
