LEXINGTON, Ky. (FOX 56) – Here are five things to know before you go to bed on Jan. 21, 2022.

National Pie Day!

I hope you were able to enjoy some pie today because it is National Pie Day.

And it’s not just for apple pie. Dessert pies of all kinds are being celebrated.

The Romans made them as goat cheese and honey pies. England filled them with meat 800 years ago and puritans brought us pumpkin and pecan pies.

COVID-19 detection pin

Researchers at a major university came up with a device to help you detect COVID-19 risks while you’re out and about.

Scientists at yale university’s school of public health developed a wearable pin, which captures virus-laden aerosols onto a testing surface.

The passive air sampler clip can be worn on outer clothing and can be used in high-risk settings such as health care and restaurants.

Yale health said the clips are easy-to-use, non-invasive, and low-cost.

They could be publicly available in the near future.

American Christmas trees

Christmas only comes once a year, but, some Americans like to keep the comfort and joy going all through January by leaving up their trees.

Holiday decor site “Treetopia” surveyed about 3,500 people to find out how long their Christmas trees stay up after the holiday.

The country averages just under three weeks.

Arizona, Illinois, and Maryland go for the longest at about four weeks.

The rest are maybe between two-to-three weeks.

General Motors adding more jobs

General Motors (GM) is set to announce a major investment into their development of electric vehicles this week.

GM is planning to spend $6.5 billion and hire 4,000 new workers for two plants in Michigan.

State officials are set to approve an incentive package this upcoming Tuesday.

Even though electric vehicles only accounted for three percent of new sales in 2021, forecasters believe this will rise in the coming years.

COVID-19 and fertility

New evidence shows getting a covid-19 vaccine does not impact a couples’ chance of having a baby.

Researchers found getting vaccinated against the coronavirus does not impair fertility in men or women.

However, a COVID-19 infection could potentially affect a man’s fertility for up to 60 days.

Researchers said men experienced a slightly lower chance of conception after being infected.

The findings are published in the American Journal of Epidemiology.
