A new study reveals that bacteria can survive antibiotic treatment through two fundamentally different "shutdown modes," not just the classic idea of dormancy. The paper is published in the journal Science Advances.
Angiosperms, also known as flowering plants, represent the most diverse group of seed plants, and their origin and evolution have long been a central question in plant evolutionary biology. Whole-genome duplication (WGD), or…
In recent decades, scientists have debated whether a seven-million-year-old fossil was bipedal—a trait that would make it the oldest human ancestor. A new analysis by a team of anthropologists offers powerful evidence that Sahelanthropus…
For the first time, scientists have reconstructed the ancient genomes of human betaherpesvirus 6A and 6B (HHV-6A/B) from archaeological human remains more than two millennia old. The study, led by the University of Vienna and University of…
Every day, millions of people use thermal paper without thinking about it. Receipts, shipping labels, tickets, and medical records all rely on heat‑sensitive coatings to make text appear. More specifically, heat triggers a reaction between…
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…
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…
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.
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…
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…
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,…
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…
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…
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…
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…
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…
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…
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…
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…
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.
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…
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,…
