[00:00.00]Nasty, pesky, blood sucking mosquitoes.
[00:03.56]Is it true are some people bitten more?
[00:06.80]It's true everybody asks.
[00:07.71]After a three-year study, 
[00:09.30]the scientists at Rockefeller University 
[00:11.21]have discovered one of the reasons why.
[00:13.24]Long chain carboxylic acids.
[00:15.40]Carbox what? - Carboxylic acids, 
[00:18.38]which is a fancy technical term for these 
[00:20.84]greasy molecules that live on your skin.
[00:23.90]Bacteria eat those acids, and create a stink.
[00:26.69]Limburger cheese, stinky cheese, 
[00:29.73]blue  cheese, feet foot odor. 
[00:32.73]That's the smell? - That's the smell.
[00:34.14]And some of us smell more than others, 
[00:36.61]stand out during the study was subject 33.
[00:39.74]We found this exceptionally 
[00:41.94]a mosquito attractive person.
[00:43.82]Scientist Maria Elena De Obaldia 
[00:46.10]led the research, Nylons worn 
[00:48.26]by the subjects were placed in a device 
[00:49.96]she built herself, the mosquitoes 
[00:51.95]were drawn to the strongest smell.
[00:54.60]When you put them head to head, it's striking.
[00:57.66]The hope is that these results 
[00:59.25]will improve repellents.
[01:00.83]In New York, mosquitoes are an annoyance, 
[01:03.15]but in much of the world 
[01:04.19]they're spreading deadly diseases.
[01:06.12]Like yellow fever and malaria, 
[01:08.10]killing more than 700 000 people a year, 
[01:11.25]better repellent will save lives.
[01:13.57]For now here's some summer barbecue advice.
[01:16.65]If you hang around with people 
[01:18.17]who are less attractive than you, you'll be 
[01:19.89]the most attractive person at the picnic.
[01:21.66]What we really need to do? is find somebody 
[01:24.18]who stinks more than we do? - Absolutely!
[01:26.45]For those unlucky people like subject 33, 
[01:29.23]the scientists say changing soaps 
[01:31.24]or your diet makes no difference, 
[01:32.98]the mosquitoes will find you.
