Attosecond core-level spectroscopy reveals real-time molecular dynamics

Posted by in categories: biological, chemistry, particle physics

Chemical reactions are complex mechanisms. Many different dynamic processes are involved, affecting both the electrons and the nucleus of the present atoms. Very often, the strongly coupled electron and nuclear dynamics induce radiation-less relaxation processes known as conical intersections. Such dynamics, which are at the basis of many biological and chemical relevant functions, are extremely difficult to detect experimentally.

Collaboration identifies rare nuclear decay in long-lived potassium isotope

Posted by in category: futurism

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.

Study of new method used to preserve privacy with US census data suggests accuracy has suffered

Posted by in category: futurism

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.

How NASA’s XRISM captures space data with just 36 pixels

Posted by in categories: biotech/medical, electronics

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.

This Chinese drone turns into a lifebuoy to rescue drowning swimmers

Posted by in categories: drones, law enforcement

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.
