Bees can count using only four brain cells

Bees can count using only four brain cells

Science
Dec. 21 (UPI) -- New research reveals how bees count using minimal brain power. To better understand bees' mathematic abilities, scientists designed a simple brain model on the computer, featuring just four nerve cells. Simulations showed the simple brain was capable of counting small quantities by closely studying one item at a time. Previous studies suggest bees count the same way. Meanwhile, humans look at the whole group of items and count them together. In lab experiments, bees can count upwards of five and can be trained to select the smaller or larger of two values. Bees can even choose the value of zero, when trained to select the lesser of two quantities. The latest research suggests bees don't need to understand complex math to achieve these feats of quantitative comparison. By...

Back in Black: Your Favorite Foods, Only Healthier

Health
When it comes to plant-based foods, deep, vibrant colors are one of the best indicators of what's healthiest. The pigments that give plants their color also provide the antioxidants that protect against heart disease, inflammation, and certain cancers.

Only 60 percent of U.S. seniors got flu shots this season, survey says

Health
Nov. 30 (UPI) -- Only about 60 percent of seniors in the U.S. have gotten a flu shot this season, a survey says. Results from the December Health Flu Shot Monitor, released Friday by health insurance company Clover Health compiled flu shot data Nov. 19 to Nov. 29 for people 60 and older. That number is not much better than the 41 percent of seniors who reportedly received flu shots in November's Flu Shot Monitor, the company reported. Clover says that Medicare Advantage has even talked about the importance for seniors to get flu shots. According to AARP, more than 12,000 people died during last year's flu season from the illness. The Centers for Disease Control and Prevention reports that fewer people traditionally get flu shots past November. "In recent years, for example, it's estimate...

Finance
How Brexit could end flights in and out of the UK Ryanair has introduced restrictive new baggage rules that risk upsetting passengers. The budget airline said that customers will be allowed to bring only one small piece of luggage into the cabin starting in November. The bag must be small enough to fit under a seat. Passengers will be required to pay to bring additional luggage into the cabin, or have it stowed. Up to 95 customers per flight can pay £6 ($ 7.70) when they book for priority boarding and the ability to bring a 10 kilogram (22 pound) bag into the cabin. Another option is paying £8 pounds ($ 10.30) to have a 10 kilogram bag checked. Ryanair (RYAAY) said the policy was changed to cut down on delays, and it does not expect to make any additional...
