Cyborg cockroaches have actually been a thing for a while - with researchers attaching electrodes to the brain and sensory organs, enabling them to direct the insects like a remote-controlled car. Now, though, scientists at Nanyang Technological University in Singapore have taken things one step further by creating a cybernetic diving suit that can enable a cockroach to breath underwater. A 3D-printed 'backpack' attached to the insect contains a chemical oxygen generator and pumps the breathable air through special tubes. Experiments showed that the system provided enough of an oxygen supply for the insect to survive and swim around underwater...

Explanation: Some 190 million light-years away, far beyond the bright stars and nebulae of the Milky Way, these three galaxies are drawn together by gravity in a mesmerizing cosmic dance. Clearly distorted by galactic-scale gravitational interactions, large spiral galaxies NGC 6769 and NGC 6770 are seen face-on, with luminous galactic disks scarred by obscuring interstellar dust lanes. Their young blue star clusters along drawn out spiral arms are spawned in star forming regions that resulted from collisions of massive molecular clouds. Below, spiral NGC 6771 presents a more edge-on perspective, its boxy central bulge due to tidal star streams. Of...

WASHINGTON -- Three-time U.S. Olympian David Hearn has been indicted in Washington, D.C., for allegedly "maliciously" destroying the lining at the Lincoln Memorial Reflecting Pool. Hearn was indicted in the Superior Court of the District of Columbia on a single count of destruction of property worth $1,000 or more, a felony charge that carries up to 10 years in prison. U.S. Attorney for the District of Columbia Jeanine Pirro announced the charges at a press conference on Thursday, saying Hearn will face "accountability." "The indictment is in response to an incident that occurred on June 19 of 2026 in which...

Summary: Researchers have shown that ultracold atoms can be driven into a strange new quantum state called a fractional Fermi sea, where particles organize themselves in unexpected ways. The discovery points to a new phase of matter that goes beyond established quantum theories and could expand the possibilities of quantum simulation...The newly created state displays several unusual characteristics. Mathematical correlations between particles reveal pronounced ripples, known as Friedel oscillations, along with distinctive decay behavior across all levels of repulsive interactions.Perhaps most importantly, the state exhibits properties that differ from those expected for Tomonaga-Luttinger liquids, which have long served as the...

Even brief periods of light or moderate physical activity were associated with a reduced riskProlonged, uninterrupted sedentary behavior was associated with a significantly increased likelihood of dying of cancer, a study of more than 90,000 people showed. Every additional hour of prolonged sedentary behavior per day was linked with a 10% higher hazard of cancer mortality. Replacing an hour of sedentary behavior daily with light physical activity or with 30 minutes of moderate physical activity was associated with reduced cancer mortality risk -- which was 22% lower with an additional 5 minutes of vigorous physical activity. Similar associations were observed...

Explanation: What happens when one of the stars in a binary goes supernova? This image combines visible (yellow), ultraviolet (purple) and infrared light (cyan, red and orange) to show two supernova remnants and their surrounding environment, about 6,000 light-years away. The younger one is the well-known Jellyfish Nebula in the center (mostly in yellow). If we could see it by eye, it would appear larger than the full moon in the sky. The filament shown in purple is part of an older, overlapping supernova remnant, G189.6+3.3. A new study used data from NASA's Fermi Gamma-ray Space Telescope to piece together...

Temperatures on the ocean surface hit a record high in June, European scientists warned Wednesday, fueling fears of more dangerous heat waves this summer and fanning concerns over the escalating global climate crisis. Two separate services under the European Union’s Copernicus Earth observation program — the Copernicus Climate Change Service and the Copernicus Marine Service — announced they had both independently confirmed the record temperatures. Carlo Buontempo, director of the Copernicus Climate Change Service, warned that the rising temperatures could mark the “beginning of a new phase.” “With ocean temperatures at these levels and El Niño on the horizon, we...

...To read it, we never unrolled it physically. Instead, we scanned it with high-resolution X-rays, reconstructed the wound sheet inside the volume, flattened it into a readable surface, and used machine learning to bring out the faint traces of ancient ink...PHerc. 1667 is what survives of a larger roll: earlier attempts to open it by hand -- in the nineteenth century, and again in 1969 and the 1980s -- destroyed its outer layers and left only the compact inner core, about 8 cm of an original height of 19–24 cm. From that surviving portion we have now recovered and read...

A new study compares the carved symbolism of Göbekli Tepe’s Vulture Stone with ritual imagery from the Trypillia culture, suggesting that early farming societies in Anatolia and Eastern Europe may have shared cosmological ideas about time, death, sacred space and the movement of the heavens.At Göbekli Tepe, the famous Vulture Stone has never been easy to read. Its carved birds, snakes, scorpion, abstract signs and headless human figure have inspired competing interpretations for decades. Was it a scene of death ritual, an astronomical code, a mythic narrative, or something more complex? A new study argues that the answer may not...

NASA's Ingenuity helicopter was designed to fly five times on Mars, instead it flew 72. For nearly three years, the four-pound drone defied expectations, becoming the first aircraft to achieve powered flight on another planet. It scouted terrain, mapped hazards, and proved aviation works in Mars' thin atmosphere. On January 18, 2024, during what should have been a routine test, its rotor blades shattered on landing, ending its flying but not its mission. In a valley sculpted by ancient rivers, the small helicopter now rests partially buried in red dust, one blade severed and lying 49 feet away in...

This hybrid design offsets the energy required to initiate and sustain the plasma. - Realta Fusion ============================================================ An experimental fusion reactor in Madison, Wisconsin, has achieved a technical milestone by converting plasma energy directly into usable electricity for the first time in the private sector. The successful trial used the Wisconsin HTS Axisymmetric Mirror, a research device operated alongside the University of Wisconsin-Madison. The newly developed hardware drew multiple amperes of electrical current at an electrical potential of roughly 100 volts. It produced enough output to illuminate several incandescent light bulbs. Realta Fusion, the company developing this magnetic mirror fusion...

Picture this: You're enjoying a delicious bowl of mushroom soup, when suddenly you notice hundreds of tiny people dressed in cartoonish clothing marching across your tablecloth, jumping into your bowl, swimming around, and clinging to your spoon as you lift it for another taste. You're not dreaming — you've just experienced the effects of a mushroom known scientifically as Lanmaoa asiatica. It belongs to an entirely different class of Fungi than the more commonly known “magic mushrooms” and remains far more mysterious.

Explanation: Although they look like cotton candy, you cannot eat these clouds! Taken in Cádiz, Spain, today's image features the Rho Ophiuchi complex, a rich tapestry of young and old astronomical phenomena. This colorful cloud complex is a nearby star-forming region containing hundreds of young stellar objects, including protostars and T Tauri stars. Light from the triple star system at its center reflects off of small dust grains to create the blue reflection nebula. Ultraviolet light from hot stars ionizes the surrounding hydrogen gas, creating the red emission nebula. Antares, a red supergiant big enough to engulf the Solar System’s...

Explanation: Why are parts of this asteroid's surface so smooth? The answer seems likely to do with the dynamics of an asteroid that is a loose pile of rubble rather than a solid rock. The unusual asteroid Itokawa was visited by the Japanese spacecraft Hayabusa in 2005 which imaged and documented its unusual structure and mysterious lack of craters. Analyses of the border regions between smooth and rugged sections indicate that jostling of the asteroid might be creating segregation between large and small rocks near the surface, like the Brazil nut effect. The robotic Hayabusa actually touched down on one...

Scientists say they have built a cell from scratch for the first time that can feed, grow and replicate like a natural cell. This breakthrough in synthetic biology could usher in an era of made-to-order organisms that function like living machines. Kate Adamala, a synthetic biologist and professor at the University of Minnesota, and her team constructed the cell piece by piece from nonliving chemical components. The creation is a limited and fragile prototype, but it could help scientists better understand the origins of life and could potentially be programmed to help mitigate some of the world’s biggest biological problems....

Recent studies on fossils found at the Dmanisi archaeological site in the Republic of Georgia are changing the way scientists have understood the initial migration out of Africa by humans. For decades, the commonly accepted theory about the earliest migration out of Africa was that one species of human, Homo erectus, migrated out of Africa approximately 1.8 million years ago. But the new study, which was published in PLOS ONE, now indicates that this pivotal migration could have involved more than one human species.This facial reconstruction represents a male individual from the Dmanisi excavation.
