After saying it would run out of funds by March, California’s last-resort fire insurance provider will impose a special charge of $1 billion on insurance companies — which will in turn pass the costs along to homeowners — the first such move in more than three decades.
The state Insurance Department today approved a request from the provider, the FAIR Plan, to impose the charge and ensure it stays solvent as it covers claims from victims of the Los Angeles County fires, the department said in an order by Commissioner Ricardo Lara.
Most California home and fire insurance customers will see temporary fees added to their insurance bills as part of the charge, known as an assessment — marking the first time insurance companies will have imposed an assessment directly on customers.
The FAIR Plan is a pool of insurers required by law to provide fire insurance to property owners who can’t find insurance elsewhere. Its customer base has grown dramatically in the past several years as insurance companies have increasingly refused to write or renew policies in the state, citing increased risk of wildfires. It now has more than 451,000 policies.
Many LA fire victims have insurance through the FAIR Plan. Residents of the Pacific Palisades, where thousands of structures burned last month, held 85% more FAIR Plan policies in September than they had a year prior.

Human capital—encompassing cognitive skills and personality traits—is critical for labor market success, yet the personality component remains difficult to measure at scale. Leveraging advances in artificial intelligence and comprehensive LinkedIn microdata, we extract the Big 5 personality traits from facial images of 96,000 MBA graduates, and demonstrate that this novel “Photo Big 5” predicts school rank, compensation, job seniority, industry choice, job transitions, and career advancement. Using administrative records from top-tier MBA programs, we find that the Photo Big 5 exhibits only modest correlations with cognitive measures like GPA and standardized test scores, yet offers comparable incremental predictive power for labor outcomes. Unlike traditional survey-based personality measures, the Photo Big 5 is readily accessible and potentially less susceptible to manipulation, making it suitable for wide adoption in academic research and hiring processes. However, its use in labor market screening raises ethical concerns regarding statistical discrimination and individual autonomy.

The origins of COVID-19 remain uncertain despite extensive research. A new study published in Advances in Biomarker Sciences and Technology (ABST) takes an AI-driven approach to analyze DNA methylation patterns at 865,859 CpG sites in blood samples from early COVID-19 patients.
Led by Zhengjun Zhang from the University of Wisconsin’s Department of Statistics, the study used max-logistic intelligence to identify strong genetic links. The findings suggest that COVID-19 may have resulted from the natural fusion of two rare infectious diseases — glanders and Sennetsu fever — combined with common human illnesses.
Which, of course, doesn’t speak to whether it arose naturally or by means of ‘gain of function’ research by ill-intentioned people.

Scientists have uncovered a new way that cells control their genes — and it may rewrite our understanding of “epigenetics.”
Epigenetics is a form of DNA modification that doesn’t affect the DNA sequence itself. Instead, it describes when chemical groups attach to specific genes, thus switching those genes on or off, or else changing the 3D shape of chromosomes.
Now, in a study published Jan. 17 in the journal Cell, scientists have uncovered a whole new method of gene regulation that involves epigenetic tweaks made to both DNA and its molecular cousin RNA, at the same time.

Killer whales (Orcinus orca) have been documented to prey on white sharks (Carcharodon carcharias), in some cases causing localised shark displacement and triggering ecological cascades. Notably, a series of such predation events have been reported from South Africa over the last decade, with killer whales specifically targeting sharks’ liver. However, observations of these interactions are rare, and knowledge of their frequency across the world’s oceans remains limited. In October 2023, a 4.7?m (total length) white shark carcass washed ashore in southeastern Australia, coinciding with reports from citizen scientists of killer whales hunting a large, unidentified prey item in the area. Visual inspection of the carcass revealed that the liver, digestive, and reproductive organs were missing, and the presence of four distinctive bite wounds, one of which was characteristic of killer whale liver extraction as seen in South Africa. Genomic analyses performed on swabs taken from the bite wounds confirmed the presence of killer whale DNA in the major bite area, while the other bites were embedded with genetic material from the scavenging broadnose sevengill shark (Notorynchus cepedianus). These results provide confirmed evidence of killer whale predation on white sharks in Australia and the likely selective consumption of the liver, suggesting predations of this nature are more globally prevalent than currently assumed.

After Oklahoma approved a request by the Catholic Church to open a charter school in 2023, lawsuits quickly followed. Courts at both the state and federal levels ruled against the church, finding that a publicly funded school promoting religion would be unconstitutional.
Now, the U.S. Supreme Court has taken up the case, signaling that the justices are willing to consider overturning a longstanding legal precedent protecting the separation of church and state. If the court allows St. Isidore of Seville Catholic Virtual School to become the first government-funded religious school in the country, the consequences for religious education — including for Jewish schools — could be far-reaching.
The school’s backers argue that charter schools should be allowed to teach religion because they are not technically government institutions. They also contend that as long as a state permits charter schools — and nearly all states do — excluding only religious ones violates the constitutional guarantee of religious freedom.
In St. Isidore of Seville Catholic Virtual School v. Drummond, the fate of the school will be decided by a court whose conservative supermajority has steadily expanded religion’s role in public life. The court previously ruled in favor of a public high school football coach who wanted to pray with students on the field, and has allowed government voucher funding for religious schools.

Delaware has long been considered a business-friendly state due to its corporate tax advantages, and is home to multiple large companies. However, backlash against the First State has intensified after Delaware Judge Kathaleen McCormick ruled that Tesla CEO Elon Musk’s record-breaking $56 billion compensation package was excessive.
Musk, who has become increasingly influential in both the political and corporate world, urged companies to pull out of the Democratic-led state. In February 2024, he announced that SpaceX was relocating its incorporation from Delaware to Texas, following Tesla’s corporate move from California to Texas in 2021.

Despite the Biden-Harris administration’s “whole of government” attempt to increase unionization, the percentage of American workers belonging to unions notched down each of the past four years of their administration.
Marking yet another record low, 9.9% of American workers belonged to unions in 2023. This follows a steady decline from 13.4% at the turn of the century in 2000, and from a high of about 33.5% in the mid-1950s.
While the media reports have documented new unionization efforts—including some successes—in recent years, those newly-unionized jobs haven’t been enough to replace unionized job losses and other workers choosing to ditch their unions.

Homeschool families in Virginia celebrated a victory Thursday after the Virginia state Senate backed away from a bill that threatened religious exemptions for homeschoolers.
SB 1031 sought to get rid of an exemption that permits families in the state to homeschool their children because of their religious convictions. After initially voting to pass the bill, the Senate Finance and Appropriations Committee acted on a motion to reconsider and voted 13-2 to pass by indefinitely on the bill, meaning the bill will not go to the Senate floor unless the committee takes the bill up again.
This comes after Gov. Glenn Youngkin, a Republican, said he would veto the bill in a statement to the Richmond Times-Dispatch.

The Treasury Department withdrew the United States from a global climate alliance that was launched to push the financial sector to adopt green mandates.
The so-called Network of Central Banks and Supervisors for Greening the Financial System was originally created to pressure banks and financial institutions to meet sweeping global climate targets, many of which have been set during United Nations summits. The Treasury Department said late Thursday that the alliance’s mission doesn’t align with the Trump administration’s “priorities to grow the U.S. economy and American jobs.”
The announcement is part of the Trump administration’s move to exit what it considers to be harmful global climate agreements. And it is the latest signal to the international community that the United States under Trump’s leadership will seek to prioritize domestic energy production over commitments to bolster green energy and fight global warming.

A clandestine tunnel discovered on the US-Mexico border allowing entry from Ciudad Juarez into the Texan city of El Paso will be sealed by Mexican authorities, an army official said Saturday, adding that its construction was under investigation.
Discovered on January 10 by US and Mexican security agencies, the tunnel measures approximately 300 meters (1,000 feet) in length on the Mexican side and is equipped with lighting, ventilation and is reinforced to prevent collapses.
Hidden in a storm sewer system operating between both cities, its access is about 1.8 meters high and 1.2 meters wide (6 feet high and 4 feet wide), making for easy passage of people or contraband, said General Jose Lemus, commander of Ciudad Juarez’s military garrison, which is guarding the tunnel.

research team led by scientists at Northwestern University has developed the first-ever two-dimensional mechanically interlocked material with high flexibility and strength. In the future, this could be used to develop lightweight yet high-performance body armor and other such tough materials, a press release said.
It was in the 1980s that Fraser Stoddart, then a chemist at Northwestern University, first introduced the concept of mechanical bonds. Stoddart then expanded the role of these bonds into molecular machines by enabling functions like switching, rotating, contracting, and expanding in multiple ways and using them to develop interlocked structures, which also won him the Nobel Prize in 2016.
Researchers have been working on developing mechanically interlocked molecules with polymers for decades but have failed. “In organic chemistry, it is pretty straightforward to form so-called “medium-sized rings” that are 5-8 atoms around. But such rings are too small to thread another molecule through them,” explained William Dichtel, a professor of chemistry at Northwestern University in an email to Interesting Engineering.

2024 marks the 40th anniversary of the iconic Terminator franchise, which has captivated audiences with its thrilling storyline and futuristic concepts. One intriguing question that often arises when watching these films is: How does a time-traveling robot, like the Terminator, never have to worry about running out of battery power during its mission?
Maybe in the future depicted in the movie, they possess advanced technology that allows them to operate with remarkable efficiency and longevity.
The future is now. On January 8, Betavolt Technology, the Beijing-based start-up, announced the successful development of the world’s first micro-atomic energy battery. In a press conference, company CEO Zhang Wei revealed they have created an innovative new power source that combines nickel-63 isotope decay and China’s first diamond semiconductor module. This integration allows the battery to be dramatically miniaturized while maintaining low production costs.
At just 15x15x5 mm, smaller than a coin, the BB100 battery produces 100 microwatts of energy safely and stably for 50 years without recharging. The nuclear battery generates power every second and minute, producing 8.64 joules of energy per day and 3,153 joules of energy per year. The modular design means multiple batteries can be connected to deliver higher output. The stable, zero-emission energy could help power AI and autonomous technologies driving China’s next revolution.

Transitioning to a green economy demands significantly more critical metals—such as copper, rare earth elements, and cobalt—than current supplies can meet. To address this shortage, it is essential to discover new metal resources formed through different geological processes in previously unexplored regions.
New research published on January 8, 2025, in Nature, led by Dr. Chunfei Chen during his postdoctoral work with the Earth Evolution research group at Macquarie University, sheds light on where and how critical metals likely accumulate. The study identifies the margins of ancient continental cores as promising locations for these metal deposits and explains the geological mechanisms behind their formation.
“These cores are the thickest, bowl-shaped, parts of tectonic plates. Melts that form below their centers will flow upwards and outwards towards the edges, so that volcanic activity is common around their edges,” says Chen.

Transgenic mice with increased amyloid-? (A?) production show several aspects of Alzheimer’s disease, including A? deposition and memory impairment. By repeatedly treating these A?-forming mice with scanning ultrasound, Leinenga and Götz now demonstrate that A? is removed and memory is restored as revealed by improvement in three memory tasks. These improvements were achieved without the use of any therapeutic agent, and the scanning ultrasound treatment did not induce any apparent damage to the mouse brain. The authors then showed that scanning ultrasound activated resident microglial cells that took up A? into their lysosomes. These findings suggest that repeated scanning ultrasound may be a noninvasive method with potential for treating Alzheimer’s disease.

In September, Canon shipped the first commercial version of a technology that could one day upend the making of the most advanced silicon chips. Called nanoimprint lithography (NIL), it’s capable of patterning circuit features as small as 14 nanometers—enabling logic chips on par with Intel, AMD, and Nvidia processors now in mass production.
The NIL system offers advantages that may challenge the US $150 million machines that dominate today’s advanced chipmaking today, extreme ultraviolet (EUV) lithography scanners. If Canon is correct, its machines will eventually deliver EUV-quality chips at a fraction of the cost.
The company’s approach is entirely different to EUV systems, which are made exclusively by Netherlands-based ASML. The Dutch company uses a complex process that starts with kilowatt-class lasers to blasting molten droplets of tin into a plasma that glows with a 13.5 nanometer wavelength. This light is then steered through a vacuum chamber by specialized optics and bounced off a patterned mask onto a silicon wafer to fix the pattern onto the wafer.
In contrast, Canon’s system, which was shipped to Defense Department-backed R&D consortium the Texas Institute for Electronics, seems almost comically simple. Put simply, it stamps the circuit pattern onto the wafer.

What if a clinician could 3D print something through your skin, constructing an implant or replacement organ underneath layers of tissue? The world of medicine would be transformed: a host of surgical procedures, which come with a variety of risks, could be performed without ever lifting a scalpel.
A collaborative, NIH-funded team is working to make this Star Trek-like fiction a reality. Their work, published today in Science, outlines a method to print biocompatible structures through thick, multi-layered tissues. The principle? Focused ultrasound, combined with a novel ultrasound-sensitive ink.
“Focused ultrasound has been used for decades to treat a wide variety of conditions, underscoring its safety and utility as a clinical tool,” said Randy King, Ph.D., a program director in the Division of Applied Science & Technology at NIBIB. “This potential new application, built on years of technology advancements, could set the stage for something previously thought impossible: through-tissue 3D ultrasound printing.”

When a pregnant woman had her blood sampled back in 1972, doctors discovered it was mysteriously missing a surface molecule found on all other known red blood cells at the time.
After 50 years, this strange molecular absence finally led to researchers from the UK and Israel describing a new blood group system in humans. In September, the team published their paper on the discovery.
“It represents a huge achievement, and the culmination of a long team effort, to finally establish this new blood group system and be able to offer the best care to rare, but important, patients,” UK National Health Service hematologist Louise Tilley said, after nearly 20 years of personally researching this bloody quirk.
While we’re all more familiar with the ABO blood group system and the rhesus factor (that’s the plus or minus part), humans actually have many different blood group systems based on the wide variety of cell-surface proteins and sugars that coat our blood cells.
Our bodies use these antigen molecules, amongst their other purposes, as identification markers to separate ‘self’ from potentially harmful not-selves.

Archaeologists once believed the ancient Amazon rainforest was an inhospitable place, sparsely populated by bands of hunter-gatherers. But the remains of enormous earthworks, pyramids, and roads from Bolivia to Brazil discovered over the past 2 decades have proved conclusively that the Amazon was home to large, complex societies long before European colonizers arrived. Now, there’s evidence that another human society—the oldest yet—left its mark on the region: A dense network of interconnected cities, now hidden beneath the forest in Ecuador’s Upano Valley, has been revealed by the laser mapping technology called lidar. The settlements, described today in Science, are at least 2500 years old, more than 1000 years older than any other known complex Amazonian society.
Lidar, which allows researchers to see through forest cover and reconstruct the ancient sites below, “is revolutionizing our understanding of the Amazon in pre-Columbian times,” says Carla Jaimes Betancourt, an archaeologist at the University of Bonn who wasn’t involved in the new work. Finding such an ancient urban network in the Upano Valley highlights the long-unrecognized diversity of ancient Amazonian cultures, which archaeologists are just beginning to be able to reconstruct.

Around the world, people celebrate Public Domain Day on January 1, the day in which copyright expires on some older works and they enter the public domain in many different countries.
In the U.S. Constitution, copyright terms were meant to be very limited in order to “promote the Progress of Science and useful Arts.” The first copyright act, written in 1790 by the founding fathers themselves, set the term to be up to twenty-eight years.
But since then, powerful corporations have repeatedly extended the length of copyright to promote not the progress of society, but their profit. The result is that today in the U.S., work only enters the public domain ninety-five years after publication—locking our culture away for nearly a century.
2019 was the year in which new works were finally scheduled to enter the public domain, ending this long, corporate-dictated cultural winter. And as that year drew closer, it became clear that these corporations wouldn’t try to extend copyright yet again—making it the first year in almost a century in which a significant amount of art and literature once again entered the U.S. public domain, free for anyone in the U.S. to read, use, share, remix, build upon, and enjoy.
Ever since then, we’ve been celebrating Public Domain Day by preparing some of the year’s biggest literary hits for you to read on January 1.

The human brain is one of the most metabolically active organs, accounting for about 20 percent of the body’s total energy expenditure. This high level of activity generates significant waste. Smaller byproducts, such as carbon dioxide, urea, and ammonia, diffuse into capillaries and are cleared through the bloodstream. Larger neurotoxic proteins—including beta-amyloid and tau, both widely associated with an increased risk of Alzheimer’s disease, cannot be eliminated through the bloodstream alone due to their size.
In the past, it was believed that the brain lacked a lymphatic system to remove waste and relied solely on internal mechanisms for clearance.
However, in 2012, researchers discovered a specialized mechanism within the brain, analogous to the lymphatic system and capable of flushing out larger waste products from deep within the brain. This system was named the glymphatic system, a portmanteau of “glial” (referring to glial cells) and “lymphatic.” It is also known as the pseudo-lymphatic system.

One day in the near future people will look back on this era as the moment that America snatched common sense back from the jaws of unmitigated insanity. Get Woke, Go Broke is becoming a cleansing wind as thousands of companies across the US abandon DEI and social justice programs in an effort to avoid total financial collapse. That said, the last organizations you probably expected to see dumping their woke initiatives are colleges and universities. After all, these “institutions of higher learning” have been ground zero for the woke mind virus for decades.
Surprisingly, even universities are now accepting the reality that social justice is a dead ideology walking. The University of Iowa is following this trend after recently announced that it will be shutting down two social justice related departments and it will eliminate its social justice major as part of an effort to streamline and restructure some humanities offerings.

Politico, a Voice of the Crust.
With a majority of his caucus now calling on him to resign, Prime Minister Justin Trudeau is on a ski holiday, reflecting on whether to stay or go.
Trudeau is way down in the polls and facing challenges from within his party about whether he’s the right leader to unite Canadians. His decision comes as Canada braces for a tariff war when Donald Trump returns to the White House in three weeks.
Canadians will head to the polls in 2025, a federal election that could be triggered in late January if Trudeau’s foes topple the minority government when the House returns from break.

North Korea’s new warship design has emerged and it appears to be the largest the country has yet constructed. The vessel, which looks to be around the size of a typical modern frigate, or at the least a very large corvette, also appears to be designed to accommodate a vertical launch system (VLS) for missiles and a phased-array radar — two advanced items not previously seen on a North Korean design.
Photos of the new warship, the name of which has not been disclosed, were recently released by North Korea’s state-run Korean Central Television (KCTV). The vessel is seen being inspected by North Korean leader Kim Jong Un while under construction in a dry dock at Nampho Shipyard on the Taedong River estuary, on the west coast of the country.
