There is light at the end of the COVID-19 pandemic tunnel. Several vaccines against the SARS-CoV-2 virus that causes COVID-19 are now in clinical trials, with one developed by Pfizer/BioNTech already having been approved for emergency use in the United States. This has been the fastest development and rollout of any vaccine in history, starting with the first gene sequence released in January. (The previous record was held by the mumps vaccine, which took four years.)
More than a decade of virus research at the APS laid the groundwork for more effective COVID-19 vaccines medicalxpress.com - get the latest breaking news, showbiz & celebrity photos, sport news & rumours, viral videos and top stories from medicalxpress.com Daily Mail and Mail on Sunday newspapers.

A promising approach to treating cancer - called targeted alpha-particle therapy or TAT - could better harness the curative power of radiation treatments and lessen the severity of their more debilitating side effects.
TAT recruits drugs containing radioactive materials called alpha-emitting radioisotopes or radionuclides combined with cell-targeting molecules like antibodies. As alpha-emitting radioisotopes decay, they emit radiation in the form of highly energetic particles called alpha particles. Cell-targeting antibodies guide these alpha-emitting radioisotopes, like super-tiny guided missiles, to their final destination: cancer cells.
Under wraps: X-rays reveal 1,900-year-old mummyâs secrets
Results of noninvasive tests at Argonne National Laboratory point to a new way to study mummified specimens
December 09, 2020
This is the first time an intact mummy was examined using X-ray diffraction techniques.
The mummified remains of ancient Egyptians hold many secrets, from the condition of the bodies to the artifacts placed within the burial garments. Now a team of researchers has found a way to unwrap those secrets, without unraveling the mummies themselves.
Three years ago, researchers from Northwestern, in preparation for an exhibit at the Block Museum of Art, carefully transported a 1,900-year-old mummy to the Advanced Photon Source (APS), a U.S. Department of Energy (DOE) Office of Science User Facility at DOEâs Argonne National Laboratory. There scientists used powerful X-ray beams to peer inside the layers of linen and resin to examine the two-thousand-year-old bones and objects buried within.Â
Scientists have, for the first time, used X-rays to see through the outer layers of a mummy to examine the contents. The analysis reveals it was a child around five years old that likely died of disease.
