Gun injuries put over a half-million people in hospitals from 2000 to 2016, study finds

Print Tens of thousands of people are admitted to hospitals for gun injuries every year, according to a first-of-its-kind database that underscores how the societal costs of gun violence extend well beyond mortality. Developed by researchers at the Rand Corp., a California-based think tank, the study found roughly 550,000 people were admitted for gunshot wounds from 2000 to 2016, representing billions of dollars in health-care costs annually, as well as untold pain and suffering. The data comes as narrow Democratic control of Congress and the White House has ushered in hopes among advocates for new policies intended to curb gun violence in the United States. A spate of high-profile mass shootings in 2021 has ratcheted up pressure on lawmakers to act.

Researchers develop compact on-chip device to detect electric-field waveforms with attosecond time resolution -- Science & Technology -- Sott net

Credit: Understanding how light waves oscillate in time as they interact with materials is essential to understanding light-driven energy transfer in materials, such as solar cells or plants. Due to the fantastically high speeds at which light waves oscillate, however, scientists have yet to develop a compact device with enough time resolution to directly capture them. Now, a team led by MIT researchers has demonstrated chip-scale devices that can directly trace the weak electric field of light waves as they change in time. Their device, which incorporates a microchip that uses short laser pulses and nanoscale antennas, is easy to use, requiring no special environment for operation, minimal laser parameters, and conventional laboratory electronics.

Skywatch: What s happening in the heavens in May

Skywatch: What’s happening in the heavens in May Blaine P. Friedlander Jr. Venus and sun as it sets in the west-northwest. The fleet Mercury at zero magnitude, bright enough to see in the dark heavens climbs the western sky until the middle of May, when it appears to retreat again toward the western horizon to greet Venus (-3.8 magnitude, very bright) leading to a conjunction May 29, according to the U.S. Naval Observatory. The new moon occurs May 11, but you probably won’t be able to see the skinny young moon until May 13, when it nudges Mercury low on the western horizon just after dusk.
