If your Thanksgiving conversation gets a little slow this week or takes an uncomfortable turn, it may be helpful to have a quick diversion in your pocket. Thankfully, 嘿嘿视频 research continues to make strides in all kinds of arenas that are of interest to everyone you are likely to share a meal with this week. Here are a few topics you can use to spark enlightening dinner discussion:
Potential good news for canine cancer
Have a dog-loving family? They might enjoy , a 4-year-old English bulldog beating cancer after three years. A mast cell tumor, or MCT, was removed from his leg, and he came to 嘿嘿视频 for a type of chemotherapy that inhibits cell replication. Now he 鈥渟pends his days now napping and snuggling with his sister. He loves belly rubs, popcorn, blueberries, and on special occasions, french fries.鈥
Cases like this might even become a thing of the past through a clinical trial happening at 嘿嘿视频. on 800 dogs.
How much does beef actually pollute?
You may not be eating a burger this Thursday, but you can still turn the conversation topic to the beef industry and the ways it鈥檚 under siege from the growing business of meat substitutes. One way those companies have touted themselves is by highlighting the amount of greenhouse gases meat production creates, but a recent episode of the 嘿嘿视频 podcast Unfold explored the size of 鈥渃attle鈥檚 environmental hoofprint and 鈥 how 嘿嘿视频 scientists are researching ways to make livestock more sustainable.鈥
