Not So for Adults

1 Vitamin D Deficiency Linked to Allergies in Kids

Low vitamin D levels are linked to allergies in children, says research from Albert Einstein College of Medicine. Researchers examined serum vitamin D levels from 3100 children and 3400 adults and found a correlation between low levels of vitamin D and sensitivity to both environmental allergens and food allergens in children. No such correlation was found for adults. (Deficiency in children is defined as less than 15 nanograms of vitamin D per milliliter of blood.) While the research shows only an association rather than definitive proof that vitamin D deficiency causes allergies in kids, researchers say that children should consume adequate amounts of the vitamin to keep from becoming deficient. The latest recommendations call for children to take 600 IU of vitamin D daily.

Despite Meds

2 Thyroid Disease May Lower Quality of Life

Hashimoto’s Thyroiditis (HT), the most common cause of hypothyroidism, may affect quality of life - even when thyroid function is normal - says an article in the journal, Thyroid. HT, which affects women more than men, may have symptoms that include chronic fatigue and irritability, difficulty concentrating, chronic nervousness and constipation. HT, an autoimmune disorder that causes the body to produce antibodies that attack the thyroid, is treated with thyroid hormone. However, say researchers, [the study] “raises the possibility that optimal doses of thyroid hormone will not completely ameliorate all symptoms.” Further studies are required to confirm the findings of the study and to determine if HT patients have symptoms despite thyroid replacement hormone therapy.

Letters May Be Key

3 Amelia Earhart Mystery Could be Solved by Spit

"There are several errors in the Nat'l Geo article. No one has claimed to have found Earhart's remains and an Earhart family member in the direct female line has already provided a DNA reference sample to TIGHAR."
- Ric Gillespie in the comments

The mystery surrounding Amelia Earhart's death could be solved once and for all with spit from envelopes of letters the aviator wrote to family members, says National Geographic Daily News online. While many have claimed that they've found the aviator's remains, there is currently no way to positively identify found bones as belonging to Earhart. If the scientists working on the DNA project are able to extract mitochondrial DNA and nuclear DNA from Earhart's saliva on the envelopes, they'll compare it with DNA from Earhart's relatives who are still alive. Once scientists have Earhart's DNA, they'll have the proof they need to dispute or affirm cases where potential remains have been found, perhaps finally solving one of the greatest mysteries of our time.

Only 25,000 Remain in Wild

4 Sunday Is International Polar Bear Day

Sunday, February 27 is International Polar Bear Day, says the nonprofit organization Polar Bears International. According to the National Wildlife Federation, there are fewer than 25,000 polar bears left in the wild. They're disappearing due to poaching, pollution and climate change, which destroys the sea ice polar bears depend on for hunting. To help the bears, Polar Bears International encourages you to take steps to lower your carbon footprint, such as lowering the thermostat and turning off your car engine when waiting in line. To help spread the word about International Polar Bear Day, tweet with the hashtag #pbday this weekend.

Headaches Also Hurt Waistline

5 Women with Migraines As Kids Tend to Gain Weight

Over 3,700 women were questioned about their weight and height at 18 years old, just before getting pregnant and whether a doctor diagnosed them with a migraine. Of the women who were of a normal weight, one in every six was told they had a migraine compared to one in four women who were obese. Other factors were accounted for and a history of migraines was still most strongly associated with weight gain. Previous research has linked weight gain with headaches in kids and young adults and one hypothesis is that the pain of migraines may alter diet and exercise. The study did not look at how the two are related and a study based on memories has to be interpreted with caution, but researchers believe these results warrant further investigation.
