Some nuclei of certain elements decay radioactively into nuclei of different elements. These decays can be useful or annoying depending on the context. This is especially true for potassium-40. This isotope usually decays to calcium-40, but about 10% of the time it decays to argon-40.
A small team of political scientists, statisticians and data scientists from Harvard University, New York University, and Yale University, has found that by switching to a new method to better protect privacy, the U.S. Census Department has introduced factors that reduce accuracy in some cases.

Resolve specializes in detecting “soft” X-rays, a form of light with energies 5,000 times greater than visible light. This allows it to pierce through the veil and observe the universe’s most violent and energetic phenomena: supermassive black holes, sprawling galaxy clusters, and the fiery aftermath of supernovae.
However, these 36 pixels are far from ordinary. They function as a “microcalorimeter spectrometer,” explains Brian Williams, NASA’s XRISM project scientist. Each pixel acts like a miniature thermometer, meticulously measuring the temperature change caused by an incoming X-ray. This seemingly simple act reveals a wealth of information.
Researchers take inspiration from Origami to create a lightweight, yet sturdy gripper for unmanned aerial vehicles (UAVs).
Researchers just created a biodegradable plastic using bacteria spores and thermoplastic polyurethane that could even benefit plants.
The TY-3R Air-Water Rescue Drone system was designed with maintainability in mind. Four hatches on the drone provide access for maintenance or replace batteries.
Didiok Makings envisions the TY-3R to become an integral tool for emergency responders, law enforcement agencies, and maritime organizations dedicated to safeguarding lives on water. The company has set up an after-sales department and flight test base to provide customers and operators with optimal service and training.
Researchers in China have developed a water-based battery, which is claimed to be much safer and energy-efficient than “highly flammable” non-aqueous lithium batteries.
Interestingly, the researchers say that these new batteries will be twice as energy-dense as traditional lithium-ion options. This holds the potential to revolutionize the electric vehicle industry.
Moreover, aqueous batteries use water as the solvent for electrolytes, enhancing their safety. Traditional non-aqueous lithium-ion batteries have a high energy density, but their safety is compromised due to the flammable organic electrolytes, a component that allows the battery to charge and discharge, they utilize.
