WASHINGTON The National Academy of Sciences will honor 20 individuals with awards in recognition of their extraordinary scientific achievements in a wide range of fields spanning the physical, biological, social, and medical sciences.
Dana Longcope, Montana State University, will receive the Arctowski Medal for fundamental research on the nature of solar magnetism, magnetic topology, and reconnection. The medal is presented with a $100,000 prize, and $100,000 to support research in solar physics and solar terrestrial relationships.
Patrick Keeling, University of British Columbia, will receive the Gilbert Morgan Smith Medal for excellence in published research on marine and freshwater algae. The medal is presented with $50,000 prize.
Harry W. Orf, BS 1971
Harry W. Orf, BS 1971, was Director of Molecular Biology at Massachusetts General Hospital and Principal Associate in Genetics at Harvard Medical School when he received the award. Harry received his Ph.D. degree in organic chemistry at Harvard University with Professor E. J. Corey in 1976. In 2004 he was appointed Vice President for Scientific Operations and Professor of Chemistry at the Scripps Research Institute - Scripps Florida in Jupiter, FL. Since arriving in Florida, Harry has been named to the Board of Directors of the South Florida Science Museum, the Florida Coalition for the Improvement in Math and Science, the Florida Research Consortium, and BioFlorida, and was recently named Chair of the BioFlorida Committee on Education. He retired in September, 2004 at the rank of Colonel from the 804th Medical Brigade, US Army Reserves, where he spent a year on active duty serving with the Brigade in Iraq and Kuwait, and earning a Bronze Star.
Washington: In late December, scientists in California began searching coronavirus samples for a fast-spreading new variant that had just been identified in Britain.
They found it, though in relatively few samples. But in the process, the scientists made another unwelcome discovery: California had produced a variant of its own.
That mutant, which belongs to a lineage known as CAL.20C, seemed to have popped up in July but lay low till November. Then it began to quickly spread.
CAL.20C accounted for more than half of the virus genome samples collected in Los Angeles laboratories on Jan. 13, according to a new study that has not yet been published.
It is these extreme confinement effects that ‘enables us to do chemistry that we can’t do in traditional ways’, says Angela Grommet from the Weizmann Institute of Science in Israel who recently wrote a review
2 on the topic. After 35 years of research, chemists are now starting to unlock the potential of confinement by designing molecular cages that fold up long molecules into huge macrocycles, or creating cavities that can separate deuterium from hydrogen. In the future, confined spaces could rival enzymes in their ability to catalyse reactions or protect unstable species, turning them into useful reagents.
It all started with the discovery of carcerands more than three decades ago. Donald Cram wanted to take the chemistry of crown ethers – flat, circular molecules that can capture individual metal atoms on their inside – into the third dimension. In 1985, he functionalised big cyclic molecules so pairs of them could be brought together to form a capsule. Cram called the
