From Lifehacker: The Best and Worst Airlines for Redeeming Rewards Miles [Travel]

Signing up for airline rewards miles is easy and free, and it’s easy to pile them up if you do any traveling. The trouble starts when you need to redeem those miles for tickets, or discounts. Some airlines are better than others, and the worst ones force you to jump through hoops or change your travel date to get your money’s worth, and the folks at Ideaworks looked into which airlines were the most receptive to rewards redemptions.

From Discover Magazine: 20 Things You Didn’t Know About… Allergies

peanuts

1. Our immune system may be like those small bands of Japanese “holdout” soldiers after World War II. Not knowing that the war was over, they hid for years, launching guerrilla attacks on peaceful 
villages.

2. With our living environment well scrubbed of germs, our body’s immune “soldiers” mistakenly fire on innocent peanuts and cat dander.

5. Most food allergies result from an immune response to a protein. In 2004 a team at Trinity College Dublin tried to counter that reaction by injecting mice with parasites, giving the animals’ immune systems the sort of threat they evolved to fight, thus distracting them from the food proteins.

6. The experiment worked.

7. Excited by such findings, in 2007 British-born entrepreneur Jasper Lawrence flew to Cameroon and walked barefoot near some latrines. His aim was to acquire hookworms, which he hoped would defeat his asthma and seasonal allergies.

8. That worked too.

9. Lawrence has since started a business shipping the parasites worldwide (but not here, where the FDA prohibits it). For $3,000, customers receive up to 35 hookworm larvae…

From Discover Magazine: No More Midnight Snacks? Mice That Eat at Odd Hours Get Fat | 80beats

FA=high-fat, ab libitum (eat-at-will) diet, FT=high-fat, time-restricted diet, NA=normal ab libitum (eat-at-will) diet, NT=normal diet, time-restricted

Diets tell you what you eat, but a new study suggests when you eat matters too. Of two groups of mice who were fed the same high-fat diet, the mice who could eat around the clock were much heavier than those who had food restricted to eight hours per day, in a new study published in Cell Metabolism. 

Researchers in the study gave the mice a special high-fat chow, 61% of whose calories come from fat (compared to just 13% in normal feed). The mice who chowed down all day and night became, unsurprisingly, obese, but the ones who ate the same amount of hi-fat food in only eight hours per day did not. Their body weight was comparable to mice fed an equivalent amount of calories on normal feed.

This being a study in Cell Metabolism, the researchers didn’t stop with just weighing the mice; they did a lot of molecular experiments to work out the link between timing and weight gain. Mice on high-fat, eat-whenever diets had the insulin problems associated with obesity-induced diabetes and lower expression of genes linked to breaking down fats in the …
