This week, a handful of scientists scattered around the world got surprise telephone calls announcing that they will be receiving Nobel Prizes. On Monday, the prize in medicine or physiology was announced. It went to Katalin Kariko and Drew Weissman, scientists who developed the modifications to mRNA that made the biomolecule a viable strategy for creating vaccines. On Tuesday, the Nobel in physics went to Pierre Agostini, Ferenc Krausz and Anne L’Huillier, who created techniques to illuminate the movement of electrons using attosecond-length pulses of light. And on Wednesday Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov learned that they had won the prize in chemistry for their work with tiny bits of semiconductor material known as quantum dots.
Umair Irfan, staff writer at Vox, joins guest host Flora Lichtman to talk about the winners and their advances, and to share other stories from the week in science, including an FCC fine for a satellite company’s space junk, concerns over drought in the Amazon rainforest, and a tale of fighting a coral-threatening algal bloom using hungry crabs.
Venus Lightning Debate Gets Lit
Venus is an inhospitable place. The longest any spacecraft has survived on the planet’s surface is thought to be around two hours. It’s blazing hot. It has bone-crushing atmospheric pressure and clouds made of sulfuric acid. But is there lightning?
Flybys of Venus have detected electromagnetic signals in the radio spectrum called “whistler waves” that, on Earth, are associated with lightning strikes. So some experts speculated that Venus might have lightning too—perhaps a lot of lightning. But there was no hard proof. The question of Venusian lightning has been a topic of electric debate among scientists for some 40 years.
A study published in the journal Geophysical Research Letters last month used data from the Parker Solar Probe to argue that the whistler waves around Venus may have a different cause. Research scientist Dr. Harriet George and space plasma physicist Dr. David Malaspina of the Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder join guest host Flora Lichtman to talk about the finding, and what it could tell us about planets elsewhere in the galaxy.
