CPD spokesman Anthony Guglielmi declined to comment on what Lathem said in the video, though CNN reported Lathem confessed to committing “the biggest mistake of my life,” and said the message had been encrypted. Lathem, a leading expert on the pathogens that cause the plague who had been on the Northwestern faculty since 2007, has not been seen since Cornell-Duranleau’s body was discovered in Lathem’s 10th-floor apartment on July 27.A Cook County judge on Monday issued an arrest warrant for Lathem and Andrew Warren, a 56-year-old pension and payroll officer at a branch of Oxford University in England.No longer embarrassing or, God forbid, cringe-worthy, half of all single people now use online dating sites to find love.

And it has seven protons, and it also has seven neutrons. So the different versions of a given element, those are each called isotopes. So anyway, we have our atmosphere, and then coming from our sun, we have what's commonly called cosmic rays, but they're actually not rays. You can view them as just single protons, which is the same thing as a hydrogen nucleus. But every now and then one of those neutrons will bump into one of the nitrogen-14's in just the right way so that it bumps off one of the protons in the nitrogen and essentially replaces that proton with itself. But this number 14 doesn't go down to 13 because it replaces it with itself. And now since it only has six protons, this is no longer nitrogen, by definition. And that proton that was bumped off just kind of gets emitted. But this process-- and once again, it's not a typical process, but it happens every now and then-- this is how carbon-14 forms. You can essentially view it as a nitrogen-14 where one of the protons is replaced with a neutron. It makes its way into oceans-- it's already in the air, but it completely mixes through the whole atmosphere-- and the air. And plants are really just made out of that fixed carbon, that carbon that was taken in gaseous form and put into, I guess you could say, into kind of a solid form, put it into a living form. It gets put into plants, and then it gets put into the things that eat the plants. Well, the interesting thing is the only time you can take in this carbon-14 is while you're alive, while you're eating new things.
And we talk about the word isotope in the chemistry playlist. But this number up here can change depending on the number of neutrons you have. And every now and then-- and let's just be clear-- this isn't like a typical reaction. So instead of seven protons we now have six protons. And a proton that's just flying around, you could call that hydrogen 1. If it doesn't gain an electron, it's just a hydrogen ion, a positive ion, either way, or a hydrogen nucleus. And so this carbon-14, it's constantly being formed. I've just explained a mechanism where some of our body, even though carbon-12 is the most common isotope, some of our body, while we're living, gets made up of this carbon-14 thing.
As the week-long search for a Northwestern University professor suspected in a gruesome River North stabbing continued Friday, twists added to a murder story that has captivated a city that has seen more than 400 killings already this year.
Police revealed that fugitive microbiologist Wyndham Lathem had sent an apologetic video message to his friends, family and relatives of Trenton Cornell-Duranleau, the 26-year-old hair stylist he and an Oxford University employee are suspected of killing inside Lathem’s State Street high-rise last week. Marshals Service had taken the lead in the manhunt, and urged the two fugitives to turn themselves in, and referred anyone who has seen them to send information to the department’s anonymous tip webpage,
