Melanoma: Melanoma is the most serious type of skin cancer
Posted by Shubham Ghosh Roy in category: biotech/medical
Melanoma is the most serious type of skin cancer. Often the first sign of melanoma is a change in the size, shape, color, or feel of a mole. Most melanomas have a black or black-blue area. Melanoma may also appear as a new mole. It may be black, abnormal, or “ugly looking.”
Thinking of “ABCDE” can help you remember what to watch for:

Fusion record set for tungsten tokamak WEST
Posted by Saúl Morales Rodriguéz in category: nuclear energy
By Rachel Kremen, Princeton Plasma Physics Laboratory
Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) measured a new record for a fusion device internally clad in tungsten, the element that could be the best fit for the commercial-scale machines required to make fusion a viable energy source for the world.

Attosecond core-level spectroscopy reveals real-time molecular dynamics
Posted by Saúl Morales Rodriguéz 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 Saúl Morales Rodriguéz 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 Saúl Morales Rodriguéz 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 Gemechu Taye 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.
