All life is connected in a vast family tree. Every organism exists in relationship to its ancestors, descendants, and cousins, and the path between any two individuals can be traced. The same is true of cells within organisms—each of the trillions of cells in the human body is produced through successive divisions from a fertilized egg, and can all be related to one another through a cellular family tree. In simpler organisms such as the worm C. elegans, this cellular family tree has been fully mapped, but the cellular family tree of a human is many times larger and more complex.

In the past, Whitehead Institute Member Jonathan Weissman and other researchers developed lineage tracing methods to track and reconstruct the family trees of cell divisions in model organisms in order to understand more about the relationships between cells and how they assemble into tissues, organs, and—in some cases—tumors. These methods could help to answer many questions about how organisms develop and diseases like cancer are initiated and progress.

Now, Weissman and colleagues have developed an advanced lineage tracing tool that not only captures an accurate family tree of cell divisions, but also combines that with spatial information: identifying where each cell ends up within a tissue.

Around 850,000 years ago, a toddler was decapitated and cannibalized, cut marks on one of their neck bones suggest.

The bone, which belonged to an archaic human relative, was found at the Gran Dolina cave at the archaeological site of Atapuerca in northern Spain. An analysis of the bone indicates that the child was between 2 and 5 years old when they died.

“This case is particularly striking, not only because of the child’s age, but also due to the precision of the cut marks,” Palmira Saladié, co-director of the Gran Dolina excavation, said in a statement Thursday (July 24). “It is direct evidence that the child was processed like any other prey.”

A German court on Wednesday acquitted a satirist who was charged with having approved of an assassination attempt against Donald Trump during last year’s U.S. election campaign in a social media post and disturbed the public peace.

In a quickly deleted post under his alias “El Hotzo” on X in July last year, Sebastian Hotz drew a parallel between Trump and “the last bus” and wrote “unfortunately just missed.” In a follow-up post, he wrote: “I find it absolutely fantastic when fascists die.”

Entanglement has now become the key resource in quantum information theory. It is being used in quantum teleportation and quantum cryptography, quantum computing, communication, and precision measurements.

More than 200 years after Sadi Carnot introduced the second law of thermodynamics, scientists have discovered a similar rule for the quantum world. This new “second law of entanglement” demonstrates that quantum entanglement can be altered and reversed in a controlled manner, much like the behavior of energy in classical thermodynamics. Until now, many researchers doubted this was possible.

The study could advance the understanding of entanglement’s basic properties. It also offers significant insight into effectively regulating entanglement and other quantum phenomena in practice.

Scientists have noticed many parallels between quantum entanglement and thermodynamics. One key example is entanglement entropy, which behaves like thermodynamic entropy, a measure of disorder, but in ideal, perfectly controlled quantum systems.

Scientists have used a single injection to correct gene mutations caused by an ultra-rare disease, improving symptoms and survival rates in mice.

Published in Cell, the gene editing study targeted the 2 most common mutations that cause alternating hemiplegia in childhood (AHC).

AHC is a rare neurological disorder affecting 1 in a million people. Symptoms, which usually begin before the age of 18 months, include weakness and paralysis in one or both sides of the body, muscle stiffness and, in some cases, seizures.

Current treatments help with symptom management but there is no known cure for AHC.

The researchers consisted of a team from the Rare Disease Translational Centre, the Broad Institute and the not-for-profit, RARE Hope.

Mice models were previously developed by Markus Terrey and Cathleen Lutz, vice president of the Rare Disease Translational Centre.

“Five years ago, people would have thought that going into the brain of a living organism and correcting DNA was science fiction. Today, we know this is doable,” says Terrey, who co-led the study.

BEIJING — The head of Nvidia downplayed his role in getting the U.S. government to lift a ban on selling an advanced computer chip in China and said it will take time to ramp up production once orders for the AI-processor come in.

CEO Jensen Huang, speaking Wednesday in the Chinese capital Beijing, was upbeat about the prospects for the H20 chip, which was designed to meet U.S. restrictions on technology exports to China but nonetheless blocked in April.

He met U.S. President Donald Trump before his trip and his company announced this week it had received assurances that sales to China would be approved.

“I don’t think I changed his mind,” Huang told a cluster of journalists, many of whom asked for his autograph or to take selfies with him.

A carefully organized press conference at a luxury hotel descended into a crowd scene when Huang arrived in his trademark leather jacket and started taking questions randomly in his characteristic casual style.

Export controls and tariffs were something companies must adapt to in a world he said was reconfiguring itself. He described his role as informing governments in the U.S. and elsewhere of the nature and unintended consequences of their policies.

The decision to lift the ban on the H20 chip was entirely in the hands of the American and Chinese governments and whatever trade talks they had, he said.

Asteroid 2022 YS5 is a building-sized asteroid that is scheduled to make a close approach to Earth on July 17, capturing the attention of astronomers, scientists, and space agencies worldwide. Although the asteroid is expected to fly past Earth at a safe distance, the event underscores the increasing importance of planetary defense systems, ongoing asteroid monitoring, and global cooperation in space. Both NASA and the Indian Space Research Organisation (ISRO) have confirmed that 2022 YS5 poses no threat, but are treating this event as a timely reminder of the need for continued vigilance and preparedness.

The National Aeronautics and Space Administration (NASA) has officially confirmed that asteroid 2022 YS5, measuring approximately 120 feet (36.5 meters) in diameter, will pass Earth at a distance of about 4.15 million kilometers (roughly 2.58 million miles). While that may sound like a vast distance, it is considered relatively close in astronomical terms, especially given the asteroid’s speed of over 14,000 miles per hour (22,500 km/h).2022 YS5 belongs to the Aten group of near-Earth asteroids, known for having orbits that can cross Earth’s path. However, NASA has made it clear that this particular asteroid does not qualify as potentially hazardous, as it does not meet the two key risk criteria:

  • Proximity: Within 7.4 million kilometers (4.6 million miles) of Earth
  • Size: Greater than 85 meters in diameter

Since 2022 YS5 falls short on both counts, its flyby is being monitored but not considered dangerous.

Geographers have finally figured out why some rivers form single channels, while others divide into many interwoven threads. Their findings, published in the journal Science, could transform flood planning and river restoration efforts.

“The question of what causes a river to be single-threaded or multi-threaded is pretty much as old as the field of geomorphology,” says Associate Professor Vamsi Ganti, senior author of the study at the University of California Santa Barbara.

“We found that rivers will develop multiple channels if they erode their banks faster than they deposit sediment on their opposing banks,” adds lead author Dr Austin Chadwick. “This causes a channel to widen and divide over time.”

Ganti, Chadwick and co-author Dr Evan Greenberg tracked the erosion and deposition that occurred on the banks of 84 rivers around the world. They analysed 36 years (1985–2021) of global satellite imagery with an image-processing algorithm.

The algorithm, which was originally designed to track particle motion in laboratory photos of fluid, was adapted to track channel position in floodplains.

CLIMATEWIRE | Texas knows it isn’t prepared for floods.

But the state has done little to address the risk — and the federal government under President Donald Trump is unlikely to help Texas cover the cost.

The threat was underscored last week when floodwaters ravaged central Texas — killing more than 100 people, including more than two dozen children and staff at a riverside summer camp. About 160 people were still missing as of Tuesday evening, according to Texas public safety officials.

One commenter called the graphic below an “absolutely bleak” reality, and he couldn’t be more right:

As the author of the tweet noted, it’s a “subcontinental flood” of foreigners…but not from Europe, which wouldn’t be so bad because that “subcontinental flood” would at least be comprised of people who largely share our value system, heritage, and culture. This “subcontinental flood” is pouring in from the third world, bringing along all its poverty, dysfunction, incivility, and depravity with it.

Young children being sold off into marriage with pedophilic men? Here’s what one comprehensive study found:

 

[Child marriage] was higher among girls than among boys (6.8 vs. 5.7 per 1,000), and was lower among white non-Hispanic children (5.0 per 1,000) than among almost every other racial or ethnic group studied; it was especially high among children of American Indian or Chinese descent (10.3 and 14.2, respectively). Immigrant children were more likely than U.S.-born children to have been married; prevalence among children from Mexico, Central America and the Middle East was 2-4 times that of children born in the United States.

CLIMATEWIRE | The White House is rejecting assertions from Democrats and former NOAA officials that its cuts to weather and disaster spending contributed to the Texas flooding that killed more than 100 people.

But that stance sidesteps a looming reality: The vast majority of President Donald Trump’s rollbacks to the agencies’ funding, staffing and science have yet to land.

Scientists and weather prediction experts warned that once he fulfills his agenda, areas around the country could face new risks as federal programs are degraded — from disaster warning systems and satellite observations to funding for flood projects and disaster aid. The Trump White House has proposed cutting $163 billion from the federal budget in the next fiscal year — making it the smallest in recent history.

On July 4, 2006, NASA’s space shuttle Discovery launched on a “return to flight” mission that paved the way for it and its sister ships to fly for another five years. Now, a sprawling budget enacted on Independence Day will seemingly lead to Discovery lifting off again — though this time not into space, but rather from its place in the national collection.

President Donald Trump signed into law the so-called “One Big Beautiful Bill” today (July 4), a day after the legislation was narrowly passed out of Congress with only Republican support. Deep within the 900-page bill is a provision added by Texas’ senators to transfer a “space vehicle” to a NASA center “involved in the administration of the Commercial Crew Program” and “placed on public exhibition at an entity within the Metropolitan Statistical Area where such center is located.”

The vague language, written in such a way to skirt Senate restrictions on reconciliation bills, was aimed at achieving the “Bring the Space Shuttle Home Act” introduced by Senators Ted Cruz and John Cornyn in April.

In yet another under-the-radar but significant victory for taxpayers and transparency, the President Donald Trump administration has quietly terminated federal contracts with one of the world’s largest academic publishing conglomerates.

The funding cuts for Springer Nature come following mounting evidence of political bias, scientific censorship, and misuse of federal tax dollars.

Springer is accused of helping former National Institute of Allergy and Infectious Diseases (NIAID) Director Dr. Anthony Fauci and ex-National Institutes of Health (NIH) Director Dr. Francis Collins to cover up evidence that COVID-19 leaked from a Chinese lab.

The administration canceled one active contract and allowed three others to lapse, ending taxpayer funding for the German-based publishing company.

In yet another under-the-radar but significant victory for taxpayers and transparency, the President Donald Trump administration has quietly terminated federal contracts with one of the world’s largest academic publishing conglomerates.

The funding cuts for Springer Nature come following mounting evidence of political bias, scientific censorship, and misuse of federal tax dollars.

Springer is accused of helping former National Institute of Allergy and Infectious Diseases (NIAID) Director Dr. Anthony Fauci and ex-National Institutes of Health (NIH) Director Dr. Francis Collins to cover up evidence that COVID-19 leaked from a Chinese lab.

The administration canceled one active contract and allowed three others to lapse, ending taxpayer funding for the German-based publishing company.

The company controls prestigious science journals but has increasingly come under fire for operating more like a political advocacy group than a scientific institution.

While corporate media barely acknowledged the move, conservative watchdogs are applauding the decision as a long-overdue rejection of the kind of institutional rot that flourished during the pandemic and under prior administrations.

Springer Nature has become infamous for pushing politically charged narratives, downplaying the COVID-19 lab leak theory, and censoring research to appease authoritarian regimes like China.

According to Retraction Watch, Springer was forced to issue 2,923 retractions in 2024 alone, making it one of the most error-prone publishers in the world.

Many of these retractions, critics argue, stem from ideological groupthink and a broken peer-review system overwhelmed by activism.

Fox News media reporter Brian Flood noted in June that Springer “has also been accused of significantly downplaying the Covid lab-leak theory and censoring content to appease the Chinese government.”

One of the most notorious examples was the now-discredited 2020 article in Nature Medicine titled “The Proximal Origin of SARS-CoV-2”, which sought to declare the lab-leak hypothesis “implausible” just weeks after the virus emerged.

The paper played a pivotal role in shutting down discussion of the lab-origin theory.

However, as the tide has turned, the lab-leak theory is now widely considered the most likely scenario, even by mainstream outlets.

A House Oversight Committee investigation in 2023 found that then-NIH leaders Fauci and Collins tracked the paper’s progress through the review process and pushed for its publication to silence dissent.

Dr. Collins even emailed Fauci, lamenting that the article hadn’t fully killed the lab-leak theory and asked if “there was anything more they could do.”

The committee’s conclusion was damning: “This is the anatomy of a cover-up.”

Springer’s problems don’t end with Covid.

In 2017, the company admitted to censoring hundreds of articles to conform to Chinese government demands.

And more recently, Springer retracted a peer-reviewed article on gender dysphoria after activist pressure, marking the first retraction ever for the study’s lead author, Michael Bailey.

Bailey is an experienced academic with no prior history of such action.

Critics say this pattern of suppressing politically inconvenient science represents a full-blown crisis in credibility.

And now, the Trump administration is holding them accountable.

Springer is also notorious for its sky-high publishing fees, charging researchers hundreds of millions in so-called “article processing charges.”

One study found that Springer had raked in $589.7 million in just three years, with profit margins estimated between 30% and 40%, higher than many major corporations.

So why was U.S. taxpayer money ever propping up this bloated foreign publisher in the first place?

That’s a question the Trump administration is answering with bold action.

The Trump administration has now cut around $20 million in taxpayer funds that were being funneled to Springer.

By cutting Springer’s funding and evaluating billions more in unnecessary contracts, President Trump is sending a clear message: the days of American taxpayers underwriting woke, censorious institutions are over.

In a powerful show of commitment to transparency, NIH Director Jay Bhattacharya announced on July 1 a new policy ensuring that federally funded research will now be available to the public immediately upon publication.

“The American people should have immediate free access to the science that we so generously fund through the @NIH. Starting today, we do,” Bhattacharya wrote.

In prior Republican administrations, critics say this kind of waste and ideological entrenchment would have quietly continued.

But under President Trump, the federal government is being recalibrated, slashing woke funding and restoring accountability.

Americans are no longer footing the bill for Springer’s censorship and bias.

As one source told Axios, this is just the beginning.

President Trump gets to say what no one else could: We don’t fund them anymore.
