Deer mice are known for being quite promiscuous. In fact, it is not uncommon to find a litter of deer mice with multiple fathers. Dr. Hopi Hoekstra and colleagues at Harvard University’s Department of Organismic and Evolutionary Biology discovered that the tail of deer mice sperm have longer midsections than found in monogamous mice. What this means is that their sperm…

Fevers impair brain activity

You probably already knew that fevers can cause some people to develop seizures. According to the National Institutes of Health, these so-called ‘febrile seizures’ can happen at temperatures of 102.2 degrees F and above and are most-often seen in children. The good news is that this type of seizure is usually short and does not often…

Amazing longevity of Greenland sharks

      A multi-national team of scientists sought to determine the age of Greenland sharks (Somniosus microcephalus). These animals grow rather slowly (about 1cm per year) and are the largest fish in the arctic (>500 cm long), but their longevity was not yet known. The team used radiocarbon dating of crystalline proteins found within the nuclei…

Every once in a while, I’m happy to use this blog to throw my support behind a worthy project. And there’s nothing like children’s science books about women in science! Check out the Kickstarter for Science Wide Open: Children’s Books about Women in Science, and consider joining me in helping this amazing project come to…

In true MacGyver fashion, an employee at the Rainbow Springs Nature Park in New Zealand repaired a damaged kiwi bird egg with masking tape thus protecting the chick from dehydration. The newly hatched bird was appropriately named Fissure.  

How to grow a bigger heart…

…in alligators at least. Researchers from the University of Manchester, University of North Texas – Denton, and the Rockefeller Wildlife Refuge – Grand Chenier, Louisiana teamed up to explore the effects of exposure to low oxygen on embryonic American alligators (Alligator mississippiensis). Alligator eggs are often laid in nests where oxygen concentrations can reportedly vary between 11-20% (21% is normal atmospheric levels). This…

Check out this video from Reuters (via YouTube). It summarizes an exciting study from researchers at Imperial College London who were able to stop the progression of Alzheimer’s disease in mice by administering a modified virus to the animals. The virus worked by preventing the formation of the characteristic amyloid plaques that are responsible for…

Corporal punishment in America’s public schools seems like a relic of the past — a practice we had surely banned long ago. The reality, however, is that it’s perfectly legal to physically discipline students as young as preschoolers in 19 states. And according to a new report, corporal punishment is most often used against black students and students with disabilities.

Creepy Clown Open Thread

I refer you to the book Bad Clowns, by Benjamin Radford. I remember my first bad clown. I was at a Home Bureau event with my mother, and I was probably not in kindergarten yet. Home Bureau was part of the “Ladies Auxiliary” arm of the war effort during WW II, that remained as an…

Odd Gender Pattern At Maths Olympiad

Cousin E pointed out something odd about the International Mathematical Olympiad. It’s an annual competition for high school students. And girls do super poorly in it. We ran some stats on the data for 2015 and 2016, and found that a national team with more than one female member gets less than half the median…
