It’s An Exercise Resolution
by Mark Lasbury in As Many Exceptions As Rules
More exercise is a good New Year’s resolution, but do you know why it is good for you? Sure, you strengthen your heart and may lose some weight, but exercise affects your brain most of all.

A Gift Worth Its Weight In Gold
by Mark Lasbury in As Many Exceptions As Rules
Gold is not considered a dietary micronutrient, and is the one of the most inert metals. But this is not to say it has no role in living systems; in fact, this metal is a veritable gold mine of biology. New research has led to a greater understanding of how gold can down-regulate inflammatory processes and gold complexes are being used in cancer and infectious disease treatments.... Read more »

Snow Saves Lives
by Mark Lasbury in As Many Exceptions As Rules
It may be warm for December, but the snow is coming. Recent studies are showing the unique ways that organisms depend on and use snow in order to survive. An antifreeze protein from snow fleas may lengthen the time that organs can be stored for transplant. More amazing, reindeer use the UV rays that bounce of the snow to see predators – they are the only mammals that can see in the UV range.... Read more »

Video Tip of the Week: iDigBio for access to historical specimens and more
Usually for Thanksgiving week posting is light. In the past, we’ve all done turkey breeding and genomics, cranberry genome, and some people have included apples, potatoes, and more.

Baby Giant Squids
by Dr. M in Deep Sea News
We know almost nothing about Giant Squids with mantles lengths less than 1000 mm (~40 inches). Very young squids are even more enigmatic than adults.

I Pity the Species That Doesn’t Decorate

Mr. T made mohawks and fool pitying a life goal for many.

It’s All in the Numbers - Sizes in Nature
by Mark Lasbury in As Many Exceptions As Rules
Sizes in nature are hard to compare. Can you believe that there are 200 million insects for every human on Earth? And it’s an unimaginably bigger difference when you compare bacteria number to humans. Sizes vary as well, but why? Why do bacteria have to be so small? It’s about moving molecules through a cell - diffusion.... Read more »

Thiaminases poison animals by destroying an essential vitamin
by Rosin Cerate in Rosin Cerate
A fundamental part of being alive is continually building up and breaking down organic molecules. Some molecules can only be constructed or torn down by a select group of living things, which can make it interesting for everyone else. For example, only bacteria and archaea can synthesize vitamin B12, so we have to get it through our diet or by having it administered as a drug.... Read more »

Twin Sons Of Different Mothers…… Or Fathers
by Mark Lasbury in As Many Exceptions As Rules
Can a pregnant woman get pregnant? Sounds like a riddle, but really it is superfetation. Getting pregnant in two successive cycles and having twins with different fathers really creates a problem in defining what twins actually are. Twins don’t have to be conceived at the same time, born at the same time, have the same father, or even be of the same “race.”... Read more »

Twins of Different Seasons
by Mark Lasbury in As Many Exceptions As Rules
Twins are born near the same time, that’s one of the things that makes them twins. But do they have to be born close to one another? The record is twins born 104 days apart. The key is to get the twins past 25 weeks so the lungs will be mature enough, but if one twin is delivered, the second might be subjected to delayed interval delivery to give the lungs longer to grow....

You And Mom Are Never Apart

You have more in common with your mom than you might think. Microchimerism means that an individual has cells with two different genetic profiles; some are yours and some are your mom’s. They live in your body for more than 40 years and can affect your health. Some of your cells moved into mom too – and they may help her live longer and avoid breast cancer.... Read more »
