How cells could help Artemis astronauts exercise
In 2033, NASA and China plan to send the first crewed missions to Mars. These missions will launch every two years when Earth and Mars are at the closest points in their orbits (Mars Opposition). It will take these missions six to nine months to reac.....»»
A shade closer to more efficient organic photovoltaics
Transparent solar cells will transform the look of infrastructure by enabling many more surfaces to become solar panels. Now, materials called non-fullerene acceptors that can intrinsically generate charges when exposed to sunlight could make semitra.....»»
Unveiling the mysteries of cell division in embryos with timelapse photography
The beginning of life is shrouded in mystery. While the intricate dynamics of mitosis are well-studied in the so-called somatic cells—the cells that have a specialized function, like skin and muscle cells—they remain elusive in the first cells of.....»»
Biomolecular condensates: Study reveals poor predictive power of established liquid-liquid phase separation assays
Cells buzz with millions of different biomolecules that diffuse chaotically through their substructures, yet they manage to ensure exquisite functional and spatial specificity......»»
This one Apple Fitness feature completely changed how I exercise
Sticking with a regular workout routine can feel impossible at times. But that changed after I found this one Apple Fitness feature......»»
China to send three astronauts to Tiangong space station, part of its ambitious program
China's space agency is making final preparations to send the Shenzhou-18 crew into low-Earth orbit on Thursday as part of its ambitious space program that aims to put people on the moon by 2030......»»
Scientists study lipids cell by cell, making new cancer research possible
Imagine being able to look inside a single cancer cell and see how it communicates with its neighbors. Scientists are celebrating a new technique that lets them study the fatty contents of cancer cells, one by one......»»
Researchers create artificial cells that act like living cells
In a new study published in Nature Chemistry, UNC-Chapel Hill researcher Ronit Freeman and her colleagues describe the steps they took to manipulate DNA and proteins—essential building blocks of life—to create cells that look and act like cells f.....»»
Astronauts take major step toward Starliner’s first crewed flight
After numerous delays across many years, NASA is closer than ever to launching its first astronauts aboard the Boeing-made CST-100 Starliner spacecraft......»»
Pressure in the womb may influence facial development
Physical cues in the womb, and not just genetics, influence the normal development of neural crest cells, the embryonic stem cells that form facial features, finds a new study led by UCL researchers......»»
Diamond-based quantum sensing microscope offers effective approach for quantifying cellular forces
Cells rely on constant interplay and information exchange with their micro-environment to ensure their survival and perform biological functions. Hence, precise quantification of tiny cellular adhesion forces, spanning from piconewtons to a few nanon.....»»
NASA may alter Artemis III to have Starship and Orion dock in low-Earth orbit
If it were to happen, a revised Artemis III mission could echo Apollo 9. Enlarge / This image taken by NASA's Orion spacecraft shows its view just before the vehicle flew behind the Moon in 2022. (credit: NASA) Although.....»»
Light show in living cells: New method allows simultaneous fluorescent labeling of many proteins
Observing proteins precisely within cells is extremely important for many branches of research but has been a significant technical challenge—especially in living cells, as the required fluorescent labeling had to be individually attached to each p.....»»
Key protein regulates immune response to viruses in mammal cells
Researchers have revealed the regulatory mechanism of a specific protein that plays a key role in balancing the immune response triggered by viral infections in mammal cells. These findings could help drive the development of antiviral therapies and.....»»
Researchers crack mystery of swirling vortexes in egg cells
Egg cells are the largest single cells on the planet. Their size—often several to hundreds of times the size of a typical cell—allows them to grow into entire organisms, but it also makes it difficult to transport nutrients and other molecules ar.....»»
Mobile genetic elements can inadvertently suppress bacterial immune systems, research reveals
Bacterial restriction-modification systems are responsible for protecting cells from foreign genetic material, for example, bacteriophages and plasmids. Immune systems require strict regulation, as bacteria, like humans, can have autoimmune reactions.....»»
Astronauts to patch up NASA"s NICER telescope
NASA is planning to repair NICER (Neutron star Interior Composition Explorer), an X-ray telescope on the International Space Station, during a spacewalk later this year. It will be the fourth science observatory in orbit serviced by astronauts......»»
On-demand nutrient production system for long-duration space missions
When astronauts embark on long space missions, they'll need to grow their own food because pre-packaged meals from Earth lose their nutritional value over time. The BioNutrients project at Ames Research Center's Space Biosciences Division has solved.....»»
Saturn"s ocean moon Enceladus could support life—researchers are working out how to detect extraterrestrial cells there
Saturn has 146 confirmed moons—more than any other planet in the solar system—but one called Enceladus stands out. It appears to have the ingredients for life......»»
A clinical decision support system for Earth-independent medical operations
Deep space exploration requires a paradigm shift in astronaut medical support toward Earth-independent medical operations. Currently, astronauts rely on real-time communication with ground-based medical providers. However, as the distance from Earth.....»»
Studying spaceflight atrophy with machine learning
Even intense exercise by astronauts cannot compensate for muscle atrophy caused by microgravity. Atrophy occurs, in part, by way of an underlying mechanism that regulates calcium uptake. Recent research has shown exposure to spaceflight alters the up.....»»
