Resistance to one antibiotic can make bacteria resistant or sensitive to another antibiotic, opening paths for combinatorial treatments. This study presents an approach to systematically discover and understand such antibiotic relationships.
The new sound-based method moves objects regardless of surroundings or properties.
Researchers have successfully manipulated the movement of objects using sound. They directed floating objects around obstacles in an aquatic environment, unveiling new possibilities for noninvasive, targeted drug delivery and other biomedical applications.
Researchers from EPFL’s School of Engineering employed optics-inspired techniques to achieve this object manipulation.
“Optical tweezers work by creating a light ‘hotspot’ to trap particles, like a ball falling into a hole. But if there are other objects in the vicinity, this hole is difficult to create and move around,” said Romain Fleury, head of the Laboratory of Wave Engineering in EPFL’s School of Engineering.
Three scientists are studying natural hydrogen found in the Midcontinent Rift as a potential energy source. The findings have potential for green energy.
ANCHORAGE, Alaska (AP) — An increase in the number of earthquakes under a volcano near Alaska’s largest city this year has geologists paying attention.
Mount Spurr, about 80 miles (129 kilometers) northwest of Anchorage, last erupted in 1992, spewing an ash cloud nearly 12 miles (19 kilometers) into the air, prompting flights to be canceled and people to don masks. Another eruption at the 11,100-foot (3,383-meter) stratovolcano could be severely disruptive to the city, according to the Alaska Volcano Observatory.
The observatory raised its alert status for Mount Spurr in October — from green to yellow — when the increase in seismic activity became pronounced and a ground deformation was spotted in satellite data. Observatory scientist David Fee said Friday there have been about 1,500 small earthquake below the volcano this year, compared to about 100 in a normal year.
A groundbreaking study has used patient-derived stem cells to recreate a rare genetic form of autism in the lab.
China has unveiled its most advanced quantum computer, the ‘Tianyan-504,’ featuring a 504-qubit chip named ‘Xiaohong’
Light Field Lab has launched its SolidLight Holographic and Volumetric display technologies that will power some amazing imagery of the future.
These next-generation display technologies will be used by major companies to build a wide variety of holographic images and animations. Connecting a bunch of panels together, the system can modulate 10 billion pixels per square meter.
Last year, Light Field Lab raised $50 million, adding to its war chest of $85 million raised since its inception. And now I can see where that money is going. The San Jose, California-based company gave me a theatrical tour of an animated demo of an alien that it builds in collaboration with the SETI Institute, the organization searching for extraterrestrial intelligence in our galaxy.
Earth In 2024: The International Space Station (ISS) has captured more than 825,000 images of Earth so far in 2024, documenting our planet’s changing landscapes. NASA has shared that over 5.3 million photos have been taken from the space station since it began operations, contributing significantly to studies of urban light patterns, lightning activity, and natural disasters. In 2024 alone, these images were instrumental in analysing 14 major natural disaster events, from hurricanes and floods to volcanic eruptions.
Expedition 71, one of the most prolific missions in the ISS’s history, contributed over 630,000 images, marking the highest number of photographs taken during a single mission.
According to NASA, the Crew Earth Observations (CEO) program is at the heart of this effort. Equipped with digital handheld cameras, astronauts photograph Earth from their vantage point 200 miles above the surface. The program focuses on documenting both human-induced changes — such as urban expansion and reservoir construction — and natural phenomena, including hurricanes and wildfires.
Boom Supersonic has revealed that the XB-1, the supersonic demonstrator for the Overture program, took off on a flight equipped with a shark skin-like underbelly, which reduces drag, fuel consumption, and emissions.
In its latest update to various stakeholders, Boom Supersonic shed some light on the XB-1’s eighth flight, which happened on November 16. The company stated that during the flight, it managed to confirm that the aircraft had performed safely at speeds of Mach 0.80 with the stability augmentation system being turned off.
“Our findings take us closer to solving a long-standing mystery in astronomy that will redefine our understanding of how galaxies were created in the early universe.”
The team’s research was published on Wednesday (Dec. 4) in the journal Nature.
The team made their breakthrough using the Atacama Large Millimeter Array (ALMA). ALMA is the largest astronomical project in existence comprised of 66 radio antennas situated in the Atacama Desert of northern Chile.
