Portable spectrophotometer approach predicts strawberry shelf life in real time
Graphical summary. Credit: Postharvest Biology and Technology (2024). DOI: 10.1016/j.postharvbio.2024.113189 A research group at the University of Cordoba has created a tool based on non-invasive techniques to ensure optimal strawberry quality and minimize food waste. According to the United Nations, 930 million tons of food was wasted globally in 2019. Reducing food waste is essential, as these losses occur at…

Implementing a topologically ordered time crystal on a quantum processor
Symmetry breaking in time transformation. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-53077-9 In a new study published in Nature Communications, scientists have implemented for the first time a topologically ordered time crystal on a quantum processor. This heralds a new era in quantum technology, as it has traditionally been difficult to combine crystals with topological order. However, achieving this combination increases…

Chemists say it’s time to break 100-year-old rules and rewrite textbooks
Credit: Pixabay/CC0 Public Domain Chemists at UCLA have discovered a big problem with the basic rules of organic chemistry that have existed for 100 years. That’s not true at all. And they say, “It’s time to rewrite the textbooks.” Organic molecules are primarily composed of carbon and are characterized by having a specific shape and arrangement of atoms. Molecules known…

Research team achieves acceleration of positive muon to 100keV for the first time
Schematic diagram of the experimental setup. Credit: arXiv (2024). DOI: 10.48550/arxiv.2410.11367 A team of engineers and physicists from many institutions across Japan and working at the High Intensity Proton Accelerator Research Facility have demonstrated accelerating positive muons from thermal energy to 100 keV. This is the first time muons have been accelerated in a stable manner. The group published a…

For the first time, Starship’s mega rocket booster gets caught in SpaceX’s “chopstick”
This still image taken from a SpaceX broadcast shows Starship’s superheavy booster being “caught” mid-air on its way back to its launch pad near Boca Chica, Texas. SpaceX on Sunday successfully “captured” the first stage booster of its Starship megarocket as it returned to the launch pad after a test flight, a world first in the company’s quest for rapid…

Hurricane Helen drone flight breaks data collection and flight time records
S0 Drone Sensors, Components, and Hardware. Credit: Black Swift Technologies As Hurricane Helen formed in the Gulf of Mexico, NOAA researchers collected critical data from the sea and air to better understand tropical cyclones and support forecasters at the National Hurricane Center. This real-time data gives meteorologists a clearer picture of the storm environment and structure, reducing forecast uncertainty. Researchers…

Nuclear rockets may reach Mars in half the time, but designing the reactors to power them is not easy
Nuclear-powered rockets may one day enable faster space travel. Credit: NASA NASA plans to send a crewed mission to Mars over the next decade, but the 140 million mile (225 million kilometer) journey there could take months or years round trip. This relatively long flight time is a result of the use of conventional chemical rocket fuel. The agency is…

Researchers observe nanoscale water formation in real time
Water bubbles coming out of palladium nanocubes. Observed with a transmission electron microscope. Scale bar corresponds to 50 nanometers. Credit: Vinayak Dravid/Northwestern University For the first time, researchers have witnessed hydrogen and oxygen atoms combining to form tiny nano-sized water bubbles in real time and on a molecular scale. The incident occurred as part of a new study at Northwestern…
