The collective motion of bacteria—from stable swirling patterns to chaotic turbulent flows—has intrigued scientists for decades. When a bacterial swarm is confined in small circular space, stable rotating vortices are formed. However, as the radius of this confined space increases, the organized swirling pattern breaks down into a turbulent state.

NASA’s Scientific Balloon Program has returned to Wānaka, New Zealand, for two scheduled flights to test and qualify the agency’s super pressure balloon technology. These stadium-sized, heavy-lift balloons will travel the Southern Hemisphere’s mid-latitudes for planned missions of 100 days or more.
The International Space Station supports a wide range of scientific activities, from looking out at our universe to breakthroughs in medical research, and is an active proving ground for technology for future moon exploration missions and beyond.
An international team of astrophysicists from China and Australia has for the first time determined how massive neutron stars are when they are born.
An international team of astronomers reports the detection of two new brown dwarfs orbiting distant stars using NASA’s Transiting Exoplanet Survey Satellite (TESS). The newfound objects are about 30 times more massive than Jupiter. The finding was detailed in a paper posted on March 7 to the arXiv preprint server.
In a comprehensive experimental study, an international team of researchers has confirmed the calculations of a leading turbulence simulation code to an unprecedented degree. This marks a major breakthrough in understanding turbulent transport processes in nuclear fusion devices.
Researchers have uncovered a surprising phenomenon in the material BiNiO3: when subjected to high pressure at low temperatures, its well-arranged electrical charges are disrupted, leading to a disordered “charge glass” state.
I’ve long been fascinated by the fundamental mystery of our universe’s origin. In my work, I explore an alternative to the traditional singularity-based models of cosmology. Instead of a universe emerging from an infinitely dense point, I propose that a flat universe and its time-reversed partner—an anti-universe—can emerge together from nothing through a smooth, quantum process.
It’s lights out for the first private lunar lander to pull off a fully successful moon mission.
Interconnected materials containing networks are ubiquitous in the world around us—rubber, car tires, human and engineered tissues, woven sheets and chain mail armor. Engineers often want these networks to be as strong as possible and to resist mechanical fracture and failure.

The James Webb Space Telescope has captured its first direct images of carbon dioxide in a planet outside the solar system in HR 8799, a multiplanet system 130 light-years away that has long been a key target for planet formation studies.
Dating back at least 5,000 years and located in the area beneath Fort Nevşehir, a Byzantine-era hilltop castle in Nevşehir, the mysterious underground city has proven to be one of the most shocking discoveries in recent years in the Cappadocia region where this, and other underground cities are located.
Near the region commonly referred to as “The Cradle of Civilization” we find ancient cities and structures that defy everything we know about human history and chronology since some of these structures should not exist according to mainstream scholars. We aren’t talking about the ancient underground city of Derinkuyu which is located in the same region, this gigantic underground city could prove to be one of the largest (if not the largest) ancient underground cities ever discovered on our planet. Some researchers refer to it as the greatest archaeological finding in the century.
This underground city was found by chance during a dig performed by construction workers who were preparing a new section of the city. Since the discovery, archaeologists have found over 50 historical artifacts in the underground city and most of them have already been persevered. This huge city remains largely unexplored but according to early studies, the size and features could very well rival those of the ancient underground city of Derinkuyu, which is one of the largest excavated underground cities in the region. Just like Derinkuyu, this giant underground metropolis is believed to have been a large, self-sustaining complex with many air shafts and water channels that allowed this giant underground complex to be fully autonomous. While no one knows why ancient Cappadocians built these underground cities, many scholars believe that these could have been used as safe-spots when danger loomed on the surface. The Cappadocians would retreat underground and seal themselves off with huge circular stones. According to reports from National Geographic, this ancient multilevel settlement is likely to include living spaces, kitchens, wineries, chapels, and staircases. A group of Geophysicists from the Nevşehir University conducted a systematic survey of a 4-kilometer area using geophysical resistivity and seismic tomography which showed incredible results. Out of the 33 independent measurements they took, they estimate that this ancient underground city is nearly five million square feet (460,000 square meters) plunging as deep as 113 meters, which would make it the largest underground city ever discovered, larger than Derinkuyu by a third. The exact size of the ancient city remains a mystery and some researchers estimate that this ancient city could go even deeper than previous estimates. The original builders of this and other ancient cities of the region remains a mystery. https://www.youtube.com/watch?v=jny339tcdaA One of the greatest mysteries regarding this ancient underground city is how ancient people managed to build such a vast underground city 5,000 years ago. Cappadocia or ‘Kapadokya’ means the land of the beautiful horses in Turkish. Featured image: Derinkuyu underground city in Cappadocia, Turkey.
