Synthetic repellents such as DEET seem to mask the scent of our “human perfume”—making us less obvious targets for mosquitoes. Christopher Intagliata reports. 

The Dsup protein protects DNA under conditions that create caustic free radical chemicals.

John B. Goodenough, M. Stanley Whittingham and Akira Yoshino share the 2019 Nobel Prize in Chemistry “for the development of lithium-ion batteries” that have led to portable electronic devices that are rechargeable virtually anywhere on the planet.

The power packs drive mobile phones, laptops, electric cars and solar panels

The 2019 Nobel Prize in Chemistry goes to John Goodenough, M. Stanley Whittingham and Akira Yoshino “for the development of lithium-ion batteries.”

William Kaelin, Jr., Peter Ratcliffe and Gregg Semenza share the 2019 Nobel Prize in Physiology or Medicine “for their discoveries of how cells sense and adapt to oxygen availability.” New therapies for cancer and conditions such as anemia are in the pipeline, based on these discoveries.  

The 2019 Nobel Prize in Physiology or Medicine goes to William G. Kaelin, Jr., Peter J. Ratcliffe and Gregg L. Semenza “for their discoveries of how cells sense and adapt to oxygen availability.” They identified molecular machinery that regulates gene activity in response to changing levels of oxygen.
