Researchers Have Cracked the 4,500-Year-Old Genome of a Mummy From Egypt’s First Pyramid Age

An ancient Egyptian genome has finally been unraveled after four decades of study, thanks to a sample collected from a mummy dating back to the time of the first pyramids.

The achievement marks the first complete sequencing of a genome of such antiquity collected from the region. The genetic data revealed information about the movement of people over millennia, as 80% of the individual’s DNA corresponds to ancient North Africans, while 20% is related to ancient West Asians.

The remains reveal a story of a hard life of manual labor, lived by an individual who possibly belonged to an ancient Egyptian pottery community.

A Decades-Long Genetic Quest

Forty years ago, Svante Pääbo, a Nobel Prize-winning Swedish geneticist, conducted the first successful extraction of ancient Egyptian DNA, although his work only resulted in a partial sequence. Now, scientists at the Francis Crick Institute and Liverpool John Moores University (LJMU) have conducted the first complete sequencing after working with the oldest Egyptian DNA sample ever collected.

“Forty years have passed since the early pioneering attempts to retrieve DNA from mummies without successful sequencing of an ancient Egyptian genome,” said co-author Pontus Skoglund, Group Leader of the Ancient Genomics Laboratory at the Francis Crick Institute. “Ancient Egypt is a place of extraordinary written history and archaeology, but challenging DNA preservation has meant that no genomic record of ancestry in early Egypt has been available for comparison.” 

“Building on this past research, new and powerful genetic techniques have allowed us to cross these technical boundaries and rule out contaminating DNA, providing the first genetic evidence for potential movements of people in Egypt at this time,” Skoglund added.

MIT Invents “Bubble Wrap” That Pulls Fresh Water From The Air…Even In The Driest Places In The World

MIT researchers have invented a new water-harvesting device — a high-tech version of “bubble wrap” — that can pull safe drinking water straight from the air, even in extreme environments like Death Valley, the driest desert in North America, according to LiveScience.

In a study published June 11 in Nature Water, the team described how their innovation could help address global water scarcity. “It works wherever you may find water vapor in the air,” the researchers wrote.

The device is built from hydrogel, a material that can absorb large amounts of water, sandwiched between two glass layers resembling a window. At night, the hydrogel draws moisture from the air. During the day, a special coating on the glass keeps it cool, allowing water to condense and drip into a collection system.

The hydrogel is molded into dome shapes — likened to “a sheet of bubble wrap” — that swell when absorbing moisture. These domes increase surface area, helping the material absorb more water.

LiveScience writes that the system was tested for a week in Death Valley, a region spanning California and Nevada that holds the record as the hottest and driest place in North America.

Despite the harsh conditions, the harvester consistently produced between 57 and 161.5 milliliters of water daily — about a quarter to two-thirds of a cup. In more humid regions, researchers expect even greater yields. According to MIT representatives, this approach outperforms earlier water-from-air technologies and does so without needing electricity.

One major breakthrough was solving a known problem with hydrogel-based water harvesters: lithium salts used to improve absorption often leak into the water, making it unsafe. The new design adds glycerol, which stabilizes the salt and keeps leakage to under 0.06 parts per million — a level the U.S. Geological Survey deems safe for groundwater.

Though a single panel can’t supply an entire household, its small footprint means several can be installed together. The team estimates that eight 3-by-6-foot (1-by-2-meter) panels could provide enough drinking water for a household in areas lacking reliable sources. Compared to the cost of bottled water in the U.S., the system could pay for itself in under a month and remain functional for at least a year.

Meet The Dystopian Startups Making ‘Biological Computers’ From Human Cells

Picture a dystopian future where computers don’t just mimic human thinking – they’re powered by actual human brain cells. That future is taking shape in a Cambridge, England, lab, where a groundbreaking device called CL1 is blending biology and technology in ways that could transform how we compute. Developed by Australian startup Cortical Labs and U.K.-based bit.bio, this shoebox-sized machine houses 200,000 lab-grown brain cells wired to silicon circuits, creating a “biological computer” that’s already turning heads.

Unlike traditional computers, which guzzle energy, CL1 operates with the efficiency of a human brain. “Our brains process information using a fraction of the power that modern electronics need,” Hon Weng Chong, CEO of Cortical Labs, told FT. “This could open doors to smarter robots, stronger cybersecurity, and immersive virtual worlds.”

Oh, joy.

Low-energy computing has fueled a race to develop biological systems, with Cortical Labs leading alongside competitors like FinalSpark in Switzerland and Biological Black Box in the U.S.CL1’s brain cells, grown from human skin-derived stem cells, are carefully arranged in layers: one type sparks electrical activity, while another keeps it in check. “It’s like balancing a gas pedal and brakes,” Chong explains. This precision, says bit.bio’s Tony Oosterveen, gives CL1 an edge over rival approaches using less uniform “mini-brains.” The result is a platform for testing how brain cells handle information, with early experiments already yielding insights for neuroscience and drug development.

Pharoah’s Curse Fungus Yields Breakthrough in Blood Cancer Treatment

In a stunning discovery, researchers at the University of Pennsylvania have harnessed a deadly fungus, once blamed for the “Pharaoh’s Curse,” to develop a promising new treatment for blood cancer.

This breakthrough, rooted in a toxin produced by the Aspergillus flavus mold, could offer hope to patients battling leukemia.

The story begins in the 1920s, when famed archaeologist Howard Carter opened King Tutankhamun’s tomb, an event followed by the mysterious deaths of eight team members. Whispers of a “Pharaoh’s Curse” spread, but medical experts suspected a fungal culprit.

Decades later, the excavation of King Casimir IV of Poland’s tomb in the 1970s confirmed these suspicions. Four of twelve archaeologists died within weeks, and investigators pinpointed Aspergillus flavus, a highly toxic fungus, as the cause. This mold produces asperigimycin, a toxin lethal to lung tissue but now showing remarkable potential in cancer research.

The University of Pennsylvania team discovered that asperigimycin is exceptionally effective at destroying leukemia cells in lab tests. However, the toxin required modification to become a viable cancer therapy.

Using a cutting-edge technique known as ribosomally synthesized and post-translationally modified peptides (RiPPs), the researchers engineered asperigimycin peptides.

EPA faces scientific backlash: Climate skeptics challenge 40-year consensus

On June 11, climate scientist Dr. Richard Lindzen of MIT and Princeton physicist Dr. William Happer delivered a 45-page critique to the EPA opposing proposed carbon capture regulations for power plants. Their blunt assertions—that climate policies rest on dubious science, wasted subsidies and a biased process—mark a critical moment in a decades-long debate. Their challenge reverberates with historical context: the first Senate hearing on global warming was in 1988, and is now widely criticized by skeptics as a setup. As the Biden administration accelerates climate regulations, Happer and Lindzen argue that trillions in subsidies and emission targets lack scientific grounding, urging a return to empirical rigor.

EPA’s carbon capture rules draw fire as “science-based” attack

The EPA’s May 2023 proposal mandates that coal- and gas-fired plants capture 90% of CO? emissions by 2038 or cease operations. Happer and Lindzen’s filing calls this a costly misstep, asserting that reducing greenhouse gases (GHGs) has negligible climate impact and jeopardizes global food security. Their May 2025 paper, “Physics Demonstrates That Increasing Greenhouse Gases Cannot Cause Dangerous Warming,” argues that CO?’s warming effect has been overstated due to flawed models and agenda-driven consensus. They emphasize a counterintuitive truth: higher atmospheric CO? levels could boost global crop yields by 40%, benefiting millions while producing “trivial” warming.

“Eliminating fossil fuels would be disastrous for the world’s poorest,” Lindzen warned. “Instead of taxing carbon, policymakers should trust markets and basic physics.”

The 1988 hearing that fueled the climate hubbub

The EPA’s current regulations trace their lineage to Congress’s 1988 hearings, a pivotal moment now scrutinized for manipulation. Led by Sen. Timothy Wirth (D-CO) and Sen. Al Gore (D-TN), the hearings coincided with Washington’s hottest recorded day—a deliberate scheduling choice, according to Wirth’s 2015 memoir. “We opened the windows overnight to ruin the room’s air conditioning,” Wirth disclosed, ensuring attendees were sweltering and receptive to climate alarmism.

Critics argue this marked a broader shift: replacing scientific debate with “consensus ideology.” The hearings excluded dissenting voices like former NOAA scientist Dr. Patrick Michaels, who was barred days before testifying despite years of Senate collaboration. Dr. Myron Ebell of the Competitive Enterprise Institute called the proceedings “a press conference in disguise,” setting a pattern of “censored science” that persists today.

1900 Scientists Say ‘Climate Change Not Caused By CO2’ – The Real Environment Movement Was Hijacked

Millions of people worldwide are concerned about climate change and believe there is a climate emergency. For decades we have been told by the United Nations that Carbon dioxide (CO2) emissions from human activity are causing disastrous climate change. In 2018, a UN IPCC report even warned that ‘we have 12 years to save the Earth’, thus sending millions of people worldwide into a frenzy.

Thirty-five years ago, the United Nations Environment Programme (UNEP) and the (World Meteorological Organization) WMO established the Intergovernmental Panel on Climate Change (IPCC) to provide scientific advice on the complex topic of climate change. The panel was asked to prepare, based on available scientific information, a report on all aspects relevant to climate change and its impacts and to formulate realistic response strategies. The first assessment report of the IPCC served as the basis for negotiating the United Nations Framework Convention on Climate Change (UNFCCC). Governments worldwide have signed this convention, thereby, significantly impacting the lives of the people of the world.

However, many scientists dispute with the UN-promoted man-made climate change theory, and many people worldwide are confused by the subject, or are unaware of the full facts. Please allow me to provide some information you may not be aware of.

Rethinking the Search for Extraterrestrial Life: Scientists Urge Broader Search as Exoplanet Discoveries Multiply

The search for extraterrestrial life may be operating within overly narrow parameters, as powerful tools like the James Webb Space Telescope offer new opportunities to detect more exotic biosignature gases from lifeforms thriving in conditions vastly different from those on Earth, according to new research.

MIT Professor of Physics Sara Seager led the study, which reviews the variety of gases and extreme environments that could theoretically host life in forms unlike anything found on Earth. Rather than focusing solely on Earth analogs, the study urges astrobiologists to expand the scope of their search. With over two decades of exoplanet discoveries, scientists now have a broad range of targets in the search for life — if they widen their approach.

The Direct Approach

Where earlier efforts to find extraterrestrial life, such as SETI, largely waited for signals from other advanced civilizations, modern scientists are using the James Webb Space Telescope to actively search for biosignatures produced by even the simplest life forms on distant exoplanets.

While this method is innovative in some respects, astronomers have primarily focused on Earth-like planets, which, as real-world exoplanet research shows, are less common than once speculated. By broadening their definitions of life, researchers hope to avoid overlooking potentially habitable worlds among the thousands of exoplanets identified so far.

Extremophiles and Bacteria Demonstrate Life’s Resilience

As with much exobiology research, the team began by examining the only known life-hosting planet: Earth. Some organisms here are remarkably resilient, thriving in conditions that would be lethal to others. Among the most notable are bacteria and extremophiles; tiny organisms capable of enduring Earth’s harshest environments.

Bacteria, in particular, offer hope for expanding the range of gases that might indicate life. Studies on Earth have shown that these small life forms can survive and even thrive in gases such as carbon dioxide, carbon monoxide, hydrogen, and helium. Such findings suggest that life could exist under conditions far different from those on our planet.

Extremophiles likewise challenge traditional concepts of habitability. A notable example is the tardigrade, or “water bear.” These tiny half-millimeter creatures have been observed withstanding radiation, extreme temperatures and pressures, starvation, and even direct exposure to outer space.

New Places to Look for Extraterrestrial Life

The team proposes two major avenues for reconsidering where to search for alien life, first by investigating gas planets for life forms that could exist in thick atmospheres high above their searing hot rock cores. This concept, known as a “cloud biosphere,” suggests that sub-Neptunes with permanent water clouds could theoretically support life.

Researchers point to work dating back to the 1970s, which hypothesized that chemical reactions in such environments might give rise to life. One challenge is that life requires metal ions for catalytic reactions, meaning that without contact with a planetary surface, organisms would have to rely on meteors delivering these essential ingredients.

The second avenue moves beyond just water, considering other solvents that could form life-supporting oceans for creatures very different from Earth’s. Some terrestrial organisms live in highly acidic environments, and laboratory studies have shown that even concentrated sulfuric acid can sustain organic chemistry. This opens up the possibility that conditions more acidic than any on Earth, such as the sulfuric acid clouds of Venus, could support life.

Theory suggests that consciousness is a quantum process, connecting us all to the entire universe

Our minds feel very private and unique to each of us, yet many researchers suspect our consciousness might plug into something far bigger. A controversial new framework says a quantum entanglement trick could happen inside microtubules, the tiny protein tubes that scaffold every neuron in your head.

Mike Wiest, a neuroscientist at Wellesley College, thinks those tubes may carry quantum information that never stays put.

Quantum entanglement is a phenomenon in quantum physics where two or more particles become so deeply linked that the state of one instantaneously influences the state of the other, no matter how far apart they are.

When particles are entangled, their properties – such as spin, polarization, or momentum – are correlated in such a way that measuring one particle’s state automatically determines the other’s.

This strange connection defies classical logic and puzzled Einstein, who famously dismissed it as “spooky action at a distance.”

Despite its counterintuitive nature, scientists have experimentally confirmed entanglement countless times, and it now plays a crucial role in technologies like quantum computing and quantum cryptography.

Scientists Achieve the “Impossible,” Unlocking Room-Temperature Quantum Circuits Using Magnetic Graphene

Scientists have just taken a significant step toward a long-awaited dream by creating ultra-thin, magnetically-controlled quantum devices that don’t need bulky magnets to function. 

In a groundbreaking study, a research team led by physicists at Delft University of Technology in the Netherlands has experimentally confirmed the elusive quantum spin Hall effect (QSH) in magnetic graphene, eliminating the need for an external magnetic field. This study represents a significant advancement in our understanding of quantum physics, opening up new possibilities for future technologies.

This first-of-its-kind achievement means future quantum circuitry could be smaller, faster, and far more practical than ever imagined.

“Spin is a quantum mechanical property of electrons, which is like a tiny magnet carried by the electrons, pointing up or down,”  lead author and researcher at TU Delft and Harvard University, Dr. Talieh S. Ghiasi, explained in a statement. “We can leverage the spin of electrons to transfer and process information in so-called spintronics devices.”

“Such circuits hold promise for next-generation technologies, including faster and more energy-efficient electronics, quantum computing, and advanced memory devices.” This breakthrough not only validates theoretical predictions but also propels us into a future of advanced and efficient technologies.

The findings, published in Nature Communications, detail how the team successfully induced a quantum spin Hall state in graphene by layering it on top of a van der Waals antiferromagnetic material called CrPS₄. 

This layered structure fundamentally alters the band structure of graphene, introducing spin-orbit and exchange interactions that are strong enough to give rise to exotic, topologically protected edge states. These special states allow electrons to move along the edges of the material without resistance and with their spins locked in opposite directions—a hallmark of QSH behavior.

For years, scientists have sought to harness spin—an intrinsic property of electrons—in place of charge to create next-generation “spintronic” devices. However, achieving long-distance, coherent spin transport —a state in which the spins of electrons remain in a fixed relationship over a long distance —has been notoriously difficult. Conventional methods required strong magnetic fields to split electron spins and create the necessary quantum edge states.

This study demonstrates that magnetism can originate from within. By carefully choosing a magnetic partner material for graphene—specifically, CrPS₄—the researchers induced both magnetism and spin-orbit coupling within the graphene itself. As a result, they achieved spin-polarized, helical edge states that persisted even at room temperature.

“The detection of the QSH states at zero external magnetic fields, together with the AH [anomalous Hall] signal that persists up to room temperature, opens the route for practical applications of magnetic graphene in quantum spintronic circuitries,” the researchers wrote in the study. This breakthrough paves the way for a new era of practical and efficient quantum technologies.

The experimental setup involved layering monolayer graphene on a flake of CrPS₄ and encapsulating it with hexagonal boron nitride (hBN). CrPS₄ is an air-stable magnetic semiconductor with a Néel temperature of around 38 K and strong interlayer antiferromagnetic coupling.

Using advanced electrical transport measurements, the team demonstrated that this configuration induces staggered potential and spin-orbit interactions within the graphene. These alterations open a topological gap in the graphene’s bulk, allowing gapless “helical” edge states to form—essentially creating a quantum spin Hall insulator.

Key evidence was obtained by measuring the conductance of the device near the charge neutrality point at zero magnetic fields. The conductance plateaued at precisely 2e²/h—matching theoretical predictions for QSH states where two spin-polarized channels counter-propagate along opposite edges of the device without dissipation.

The researchers confirmed these observations across various device geometries and probing configurations, ruling out conventional transport mechanisms. They also observed a large anomalous Hall (AH) effect—a separate spin-related quantum phenomenon—which persisted even at room temperature, further validating the presence of induced magnetic and spin-orbit interactions in the system.

Scientists Use Magnetic Levitation to Search for Ultralight Dark Matter

Rice University scientists have developed a sensor that uses magnetic levitation to detect quantum-level oscillations caused by theoretical ultralight dark matter moving through the Earth.

While dark matter is believed to make up most of the matter in the universe, some theories suggest that ultralight dark matter, which behaves like a continuous wave, exerts rhythmic forces that can be detected if the equipment is sensitive enough.

The research team behind the magnetic levitation sensor’s design and construction says their initial tests did not detect ultralight dark matter. However, the experiments, which were supported by the National Science Foundation, provided critical new constraints that will aid ongoing dark matter search efforts.

“Our approach brings dark matter detection into a new realm,” explained Rice University physicist Christopher Tunnell, a postdoctoral researcher and an author on the study detailing the team’s findings.

According to a statement announcing the research, Tunnell and Dorian Amaral, the study’s first author and lead analyst, teamed up with Dennis Uitenbroek and Tjerk Oosterkamp, physicists from Leiden University, to build an ultralight dark matter sensor capable of detecting movements smaller than the width of a hydrogen atom.

First, the team placed a microscopic neodymium magnet inside a superconducting enclosure cooled to near absolute zero. According to Tunnell, by using magnetic levitation to suspend the magnet in this frictionless environment, “we’re giving it the freedom to move if something nudges it.”

After the device was completed, the team began monitoring their magnetically suspended particle for the rhythmic forces caused by ultralight dark matter. If the theories were correct, they hoped to detect interaction forces that differ based on baryon and lepton numbers. Called ‘conserved quantum numbers’ in particle physics, these figures remain constant in particle interactions within a theoretical model known as B−L. This means even the smallest change should be detectable.

According to the team’s statement, their magnetic levitation sensor did not detect the predicted signal of ultralight dark matter interactions. However, Tunnell says their experiments eliminated interactions at the narrow frequency band of around 26.7 Hz targeted by their study, further narrowing the search parameters for future studies.

“Every time we don’t find dark matter, we refine the map,” Tunnell said. “It is like searching for a lost key in your house — when you do not find it in one place, you know to look elsewhere.”

In follow-up experiments, the team says they hope to try something they’ve affectionately titled after the dance the group performed when they met at a climate protest and realized taking such a measurement was even possible: the “Polonaise.” Built using heavier magnets, more stable magnetic levitation, and boasting broader frequency coverage, the team says the Polonaise will probe areas of the theoretical dark matter landscape that current detectors have not explored, “seeking to identify ultra-weak forces in the most undisturbed environments possible.”
