The Australian Space Agency has confirmed debris found in SpaceX’s NSW Snow Mountains. Key points: Three pieces of debris have so far been found The residents of the Snowy Mountains have been notified that more pieces can be found People were told to call the hotline if they found more Three pieces of space junk have so far been found in the region, which is thought to be the largest piece found in Australia since 1979. Two sections were examined by technical experts from the Australian Space Agency and NSW Police on Saturday. Police have since confirmed that they are also aware of a third piece found in the area. This space debris is estimated to be three meters long. ( ABC South East NSW: Adriane Reardon ) Authorities believe the space debris belongs to SpaceX but have been waiting for confirmation. “The agency has confirmed the debris is from the SpaceX mission and continues to engage with our US counterparts, as well as other parts of the Commonwealth and local authorities as appr

at 17 th century, Dutch scientist Christiaan Huygens hung two of his newly invented pendulum clocks on a block of wood and observed that over time, the clocks synchronized their beats. He reported this finding, which he called ‘strange sympathy’, in 1665. Three and a half centuries later, neurons in the brain were found to synchronize their activity in the same way. Neurons in the brain often synchronize in quasi-rhythmic activity, collectively producing ‘brain waves’ that can sometimes be detected even from outside the skull using electroencephalography. Synchronization in these rhythms helps neurons to exchange information efficiently, which is essential for performing important functions such as learning, memory, attention, perception, and movement. How these rhythms are generated, maintained, and abolished to suit the ever-changing needs for smooth brain operation is an active area of ​​research. In a new study published today in Cell Reports, a team of neuroscientists led by P

The graph shows the mechanism of Nepenthes gracilis. Credit: Anne-Kristin Lenzo Scientists at the University of Bristol have discovered the deadly workings of carnivorous plants. In the steamy jungles of Borneo, plants have developed innumerable tricks to help them survive and beat their neighbors. The Slender Pitcher Plant, Nepenthes gracilis, is one of the most ingenious: Its cup-shaped leaves are equipped with a hanging canopy-like cap that turns into a deadly stepping stone for ants when hit by falling raindrops. His findings, published today in Biology Letters revealing for the first time how the shut-off spring works. The team was surprised to find that instead of bending the lid on its own or in the narrow constriction between the jug’s cup and the lid, the spring was located far behind the wall of the tubular jug. The off-center location on the back of the tube has two effects. The Slender Pitcher Plant catc

Real-time video recording an 8×6-inch stretch of structural color pattern featuring a wreath in homage to the work of 19th century physicist Gabriel Lippmann. The bright colors in butterfly wings or beetle shells come not from any pigment molecules, but from how they are structured—a naturally occurring example of what physicists call photonic crystals. Scientists can manufacture their own structurally colored materials in the laboratory, but it can be a challenge to scale up the process for commercial applications without compromising optical precision. Now MIT scientists have adapted 19th-century holographic photography techniques to develop a chameleon-like film that changes color when stretched. This method can be easily scaled while maintaining nanoscale optical precision. They describe their work in a new pap

New research from the University of Cincinnati is showing early indications that light could be used as a treatment for certain ailments, including cancer. Researchers from UC, University of Illinois Urbana-Champaign and University at Buffalo published the results of their study showing light-activated proteins can help normalize dysfunction in cells in the journal. Nature Communication July 25. Research findings Research centers on the function of mitochondria, the organelles in cells that act as the cell’s “power generator” and source of energy. Organelles are small specialized structures that perform various jobs in the cell. Jiajie Diao, PhD, one of the study’s authors, says hundreds of mitochondria are constantly coming together (a process called fusion) and dividing into smaller pieces (a process called fission) to keep them in balance in healthy cells. But when mitochondria don’t function properly, an imbalance of these fission and fusion processes occurs. This imbalance can

Warmer water is flowing toward the East Antarctic ice sheet, according to our alarming new research that reveals new potential drivers of global sea level rise. Author Laura Herraiz Borreguero Physical oceanographer, CSIRO Alberto Naveira Garabato Professor, National Center for Oceanography, University of Southampton Jess Melbourne-Thomas Transdisciplinary Researcher & Knowledge Broker, CSIRO The research, published today in Nature Climate Change, suggests changes in water circulation in the Southern Ocean could jeopardize the stability of the East Antarctic ice sheet. The ice sheet, the size of the United States, is the largest in the world. Changes in water circulation are caused by shifting wind patterns, and are linked to factors including climate change. Warmer waters and rising sea levels can damage marine life and threaten human coastal settlements. Our findings underscore the urgency of limiting global warming to below 1.5℃, to prevent the most catastrophic

A group of researchers have succeeded in converting methane to methanol using a light, dispersed transition metal such as copper in a process known as photooxidation. According to an article reporting on research published in Chemical Communications, the reaction is the best obtained to date for the conversion of methane gas to liquid fuel under ambient temperature and pressure conditions (25 °C and 1 bar, respectively). The term bar as a unit of pressure comes from the Greek word for weight (baros). One bar is equivalent to 100,000 Pascals (100 kPa), which is very close to the standard atmospheric pressure at sea level (101,325 Pa). The results of this study are an important step in making natural gas available as an energy source for the production of alternative fuels other than gasoline and diesel. Although natural gas is considered a fossil fuel, its conversion to methanol produces less carbon dioxide (CO2) than other liquid fuels in the same category. In Brazil, methanol plays

Super-resolution microscopy allows fluorescence images of cells, organelles and molecular complexes to be obtained with unprecedented spatial resolution. However, this resolution is not sufficient to resolve proteins as small as a few nanometers and their interactions with other molecules or the architecture of protein complexes. This prevents, for example, the study of the molecular interactions of neurons in learning and memory processes. Overcome dynamic resolution limit Developed by the research groups of Prof Markus Sauer (Rudolf Virchow Center and Biocenter) and Dr Gerti Beliu (Rudolf Virchow Center) at the University of Würzburg, the new photoswitching fingerprint analysis enables optical imaging of dynamic interactions with other molecules in cells. “To date, no method has reliably enabled structural optical resolution in cells in the sub-10 nm range.

Scientists may have just traced the source of some of the mysterious infrared emission detected from stars and clouds of interstellar dust and gas. This Unknown Infrared Emission Band (UIE) has baffled scientists for decades; According to a new theoretical work, at least some of these bands could be produced by highly ionized buckminsterfullerene, better known as buckyballs. “I am very honored to have played a part in the extremely complex quantum chemical investigations carried out by Dr Sadjadi that have produced these very exciting results,” said astrophysicist Quentin Parker of the Space Research Laboratory of the University of Hong Kong. “First they looked at the theoretical evidence that Fullerenes – Carbon 60 – can withstand very high ionization rates, and now this work shows the infrared emission signature of the species is a perfect match for some of the most prominent Unknown Infrared Emission features known. This will help re-strengthen this area of ​​research.” Buckminste

Last week, the Northrop Grumman facility in Promontory Point/Corrinne, Utah conducted a static rocket test of its 5-stage solid-fuel booster rocket for NASA’s ongoing Artemis mission. Artemis is an ambitious unmanned space program that will take research ships through longer exploratory missions and return to Earth than has ever been attempted. The test was designed to collect data on several critical performance parameters for the rocket, in front of a large crowd of members of the public, engineers, parts suppliers, university researchers, NASA employees, school groups, and the press. The test, which was deemed successful, lasted nearly two minutes, during which time fuel burned into the scarred mountainside that was used for previous static tests. The test area itself is located about a mile away from the viewing area, which is not far enough away that the heat and vibrations from the rocket combustion itself are not palpable, even on a hot July afternoon. After a delay in the c

A UBCO researcher has created a modeling program that can help scientists plan for the restoration and conservation of coral reefs affected by climate change. Credit: Jean-Philippe Maréchal. The UBC Okanagan research team has created a computer modeling program to help scientists predict the impact of climate damage and eventual restoration plans on coral reefs around the world. This is an important goal, said Dr. Bruno Carturan, because climate change kills many coral species and can cause the collapse of entire coral reef ecosystems. However, being so complex, it is logistically difficult to study the impacts of coral reef destruction and regeneration. Real-world experiments are impractical, as researchers need to manipulate and disrupt large areas of reef, along with coral colonies and herbivorous populations, and then monitor changes in structure and diversity over the years. “Needless to say, conducting experiments that would dis

Stephan Sullivan An artist’s representation shows the researchers’ quantum functional groups (bright colored spheres) linked to larger molecules. Main takeaways: Stronger, faster. Quantum computers promise far greater speed and processing power than today’s most advanced supercomputers Quantum quantum. As these next-generation computers relied on the interaction of fragile atomic and subatomic particles, increasing their processing power proved to be a challenge. A chemical solution. Researchers have created a new molecule that has the potential to protect quantum interactions on a larger scale without the need for traditional electrical engineering tools and machines. Quantum computing, although still in its infancy, has the potential to dramatically increase processing power by exploiting the odd behavior of particles at the smallest scales. Several research groups have reported performing calculations that would take thousands of years for traditional supercomputers. In the lon

Simultaneous control over band gap and charge carrier density in semiconductors is desired in photodetectors, highly adjustable transistors, and lasers. Bernal stacked bilayer graphene is a van-der-Waals material that allows bandgap adjustment by applying an out-of-plane electric field.

An article published in Advanced Electronic Materials discusses gated bilayer graphene with adjustable bandgap, which is characterized by finite-bias transport spectroscopy and temperature-activated transport measurements. Limited-bias transport spectroscopy helps to compare different gate materials and corresponding device technologies, influencing the interference pote

Credit: Unsplash/CC0 Public Domain Scientists at Stanford University have developed a new solution to the challenge of ensuring that when carbon dioxide (CO .) 2 ) is injected underground, it really stays still. For decades, climate models have predicted that extreme heat waves like those experienced by millions of people this summer will become much more common at the level of planetary warming gases now in Earth’s atmosphere. As emissions and temperatures continue to rise, there is a growing scientific consensus that countries need to actively remove and manage CO 2 for the world to avoid warming beyond the 1.5 degree Celsius threshold above pre-industrial levels. One widely studied method of keeping carbon removed from the atmosphere over the long term involves injecting CO 2 into rock formations deep underground. But there are still questions to be resolved.
