Ernest Rutherford

Ernest Rutherford - The Father of Nuclear Physics. The discovery of radioactivity in 1896 led to a series of more in-depth investigations. In 1899 Ernest Rutherford demonstrated that there were at least two distinct types of radiation: alpha radiation and beta radiation. He discovered that radioactive preparations gave rise to the formation of gases. Working with Frederick Soddy, Rutherford advanced the hypothesis that helium gas could be formed from radioactive substances. In 1902 they formulated a revolutionary theory: that elements could disintegrate and be transformed into other elements. He was born on August 30, 1871, in Nelson, New Zealand, the fourth child and second son in a family of seven sons and five daughters. His father James Rutherford, a Scottish wheelwright, immigrated to New Zealand with Ernest’s grandfather and the whole family in 1842. His mother, née Martha Thompson, was an English schoolteacher, who, with her widowed mother, also went to live there in 1855.

How COVID-19 variants evade immune response

Image
SARS-CoV-2, the virus that causes COVID-19, uses a protein called the spike protein to recognize and enter host cells. Recent SARS-CoV-2 variants contain changes, or mutations, at a key site on the spike protein called the receptor-binding site (RBS). Some of these mutations render antibodies elicited against earlier virus strains less effective. This allows the variants to partially escape the immune response produced after vaccination or prior infection. It raises concerns that new variants could make existing vaccines less effective and draw out the pandemic. Researchers led by Dr. Ian Wilson at the Scripps Research Institute examined how and why certain mutations protect the virus. NIH’s National Institute of Allergy and Infectious Diseases (NIAID) supported the research, which appeared in Science on May 20, 2021. Proteins like the SARS-CoV-2 spike consist of long chains of building blocks called amino acids that fold into a specific shape. A mutation in the viral genome can lead t
