The protein p53, best known as the "guardian of the genome" for its role in preventing cancer, can affect blood vessels in different ways. However, it has not been clear how p53 can slow blood vessel growth in some cases and damage blood vessels in others.
Quantum particles have a social life, of a sort. They interact and form relationships with each other, and one of the most important features of a quantum particle is whether it is an introvert—a fermion—or an extrovert—a boson.
Last year was Britain's hottest and sunniest on record, the national weather service confirmed on Friday, calling it a "clear demonstration" of the impacts of climate change.
While most planets that we are familiar with stick relatively close to their host star in a predictable orbit, some planets seem to have been knocked out of their orbits, floating through space free of any particular gravitational attachments. Astronomers refer to these lonely
Antarctic icefish are famous for living without red blood cells, but they are not alone. A species of needle-shaped, warm-water fish called the Asian noodlefish also lacks hemoglobin and red blood cells. Like icefish, its veins are filled with translucent white blood, said H.
A research team led by Associate Professor Wang Yaqiong from the Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences (NIGPAS), in collaboration with colleagues from multiple domestic and international institutions, has for the first time documented
We all scream for ice-cream, especially as temperatures soar in the summer. Ancient civilizations had the same desire for a cold, sweet treat to cope with heat waves.
Three species of the melodic African warbler bird refuse to get up early and sing their customary daybreak songs when the weather is cold. This new discovery was made recently by a team of soundscape ecologists in South Africa's mountainous Golden Gate Highlands National Park.
Ever bitten into a hot pie, yelped "Hothothot!" then had your taste buds go on strike for the next week? Taste buds are a sensitive bunch.
In the shallow waters of the Florida Keys, juvenile Caribbean spiny lobsters are unwittingly meeting their doom by stumbling into naturally occurring ecological traps, according to a new study published in the Proceedings of the National Academy of Sciences.
By any measure, 2025 was not a good year for world peace.
Chess is a relatively simple game to learn but a very difficult one to master. Because the starting positions of the pieces are fixed, top players have relied on memorizing the "best" opening moves, which can sometimes result in boring, predictable games. To encourage more
When 3I/ATLAS swept past the sun in late October 2025, it became only the third confirmed visitor from interstellar space ever detected. Unlike the mysterious 'Oumuamua, which revealed almost nothing about itself during its brief flyby in 2017, or even 2I/Borisov which appeared
Attention depends on the brain’s ability to filter out distractions, but new research suggests this works best when background brain activity is quieter. Scientists found that lowering certain versions of the Homer1 gene improved focus in mice by calming neural noise. The
Amidst a tough year for science, glimmers of joy burst through in revelations from the silly to the sublime.
An analysis of stardust 180 light-years from Earth had some illuminating lessons The post Everything We Thought We Knew About How Stardust Spreads Across the Cosmos Is Wrong appeared first on Nautilus .
You have probably seen the images of the surface of Mars, beamed back by NASA's rovers. What if there were a time machine capable of roaming Earth during its remote geological past, perhaps even going right back to its beginnings, beaming back pictures of similar quality?
Within tumors in the human body, there are immune cells (macrophages) capable of fighting cancer, but they have been unable to perform their roles properly due to suppression by the tumor. A KAIST research team led by Professor Ji-Ho Park of the Department of Bio and Brain
If you were to visit a bookshop in the ancient world, what would it be like?
When the topic of central banks and the outlook for interest rates comes up, economists often turn to the so-called "star" variables to help with their predictions.
Team members working with NASA's Curiosity Mars rover created this "postcard" by commanding the rover to take images at two times of day on Nov. 18, 2025, spanning periods that occurred on both the 4,722nd and 4,723rd Martian days, or sols, of the mission.
Many stars die spectacularly when they explode as supernovae. During these violent explosions, they leave behind thick, chaotic clouds of debris shaped like cauliflowers. But supernova remnant Pa 30 looks nothing like that.
Four mice went to space as astronauts. One came back and became a mother. And that simple fact might matter more than you'd think for humanity's future beyond Earth.
Forty light-years away, seven Earth-sized planets orbit around a dim red dwarf star in one of the most tightly packed planetary systems ever discovered. The TRAPPIST-1 system has captivated astronomers since 2017, with three of its planets orbiting in the habitable zone where
The ecology of the North Atlantic is constantly changing. Sometimes it changes abruptly. Extreme events are one driver of such sudden changes. A team of researchers has discovered that a single, large-scale heat wave has affected ecosystems and trophic interactions in the
A new study presents a zero-shot learning (ZSL) framework for maize cob phenotyping, enabling the extraction of geometric traits and estimation of yields in both laboratory and field settings without the need for model retraining.
Western cultural stories tend to emphasize perseverance. But science shows that knowing when to quit has a place in our success too.
Where do the well-known cannabis compounds THC, CBD and CBC come from? Researchers at Wageningen University & Research have experimentally demonstrated for the first time how cannabis acquired the ability to produce these cannabinoids. In the process, they also developed
Parts of it are basically taking a nap The post Here’s What Happens to Your Brain When Your Mind Goes Blank appeared first on Nautilus .
Astronomers were puzzled by a black hole around 50 million times the mass of the sun with no stars, spotted by the James Webb Space Telescope – now simulations suggest it could be a primordial black hole, something we have never seen before
These birds’ drilling approach is more like extreme tennis playing than weight lifting
The “Seven Sisters” of the Pleiades are part of a much larger complex that can help reveal our galaxy’s deep history
When quantum particles work together, they can produce signals far stronger than any one particle could generate alone. This collective phenomenon, called superradiance, is a powerful example of cooperation at the quantum level. Until now, superradiance was mostly known for
The New Scientist Book Club has just finished our December read, Iain M. Banks's sci-fi novel The Player of Games - and most of us were fans of this big-thinking Culture tale
The author of the award-winning science fiction novel Annie Bot, the January read for the New Scientist Book Club, on how she created her startling protagonist
In this extract from the award-winning science fiction novel Annie Bot, the January read for the New Scientist Book Club, we are introduced to Sierra Greer's protagonist, a sex robot called Annie
A woman's body has been found to consist of varying proportions of male and female cells because of an extremely rare form of chimerism
Scientists are uncovering new clues that a cosmic explosion may have rocked Earth at the end of the last ice age. At major Clovis-era sites, researchers found shocked quartz—evidence of intense heat and pressure consistent with a comet airburst rather than volcanism or human
Moss may look insignificant, but it can carry a hidden forensic fingerprint. Because different moss species thrive in very specific micro-environments, tiny fragments can reveal exactly where a person has been. Researchers reviewing 150 years of cases found moss has helped
A new study suggests the vagus nerve may be one of the heart’s most important defenders against aging. Researchers found that keeping this nerve connected to the heart helps protect heart cells and maintain strong pumping ability. Even partial restoration of the nerve was
Astronomers tracking a nearby star system thought they had spotted an exoplanet reflecting light from its star. Then it vanished. Even stranger, another bright object appeared nearby. After studying years of Hubble Space Telescope data, scientists realized they were not seeing
A powerful 7.4-magnitude earthquake struck northern Chile in July 2024—and it wasn’t supposed to be that strong. Unlike Chile’s infamous shallow “megathrust” quakes, this one ruptured deep inside the Earth, where shaking is usually weaker at the surface. Researchers discovered
Being active boosts your daily calorie burn more than previously thought. Researchers found that increased physical activity raises total energy use without triggering the body to conserve energy elsewhere. Basic functions keep running at full speed, even as movement increases.
Researchers have confirmed the mass of a free-floating planet thanks to a lucky convergence of ground- and space-based telescopes
Chess960 involves shuffling the pieces at the back of the board, and an analysis suggests doing so can increase the complexity of the game to favour white, black or neither player
Researchers working on China's fully superconducting Experimental Advanced Superconducting Tokamak (EAST) have experimentally accessed a theorized "density-free regime" for fusion plasmas, achieving stable operation at densities well beyond conventional limits.
A new study, published in the journal Science, reveals how millennia of human migration across Pacific islands led to the introduction of invasive pig species all over the Asia-Pacific region.
About 9,500 years ago, a community of hunter-gatherers in central Africa cremated a small woman on an open pyre at the base of Mount Hora, a prominent natural landmark in northern Malawi, according to a new study coauthored by an international team based in the United States,
