WATCH: Persistence Pays Off For Squirrels

by Jenny Ludmer in Rooster's Report

Surely you can expect that the ubiquitous furry creature — a regular at your public park — is a master problem-solver. After all, squirrels must continuously stockpile acorns and occasionally raid bird feeders, all while playing in traffic and dodging hairy little beasts on leashes. But what personality characteristic most drives these exceptional abilities: persistence or flexibility? ... Read more »

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. Exercise releases helps your mood releasing a chemical in your brain just like the active ingredient in marijuana.... Read more »

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

by Mary in OpenHelix

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. But another key aspect of the holiday is to remember the past and thank those who came before. And as I was watching this video that crossed my […]... Read 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.  A recent study reports the collection of three very young Giant Squids off the Japanese coast.  The three young measured 140.8, 332, and 332 mm (5.5 and 13 inches). The heaviest of […]... Read more »

I Pity the Species That Doesn’t Decorate

by Dr. M in Deep Sea News

Mr. T made mohawks and fool pitying a life goal for many.   Another life goal for many, thanks to first name Mr, middle name period, last name T, was decorating themselves with enough gold chains to crash a third-world economy.   Although humans are the only species where decoration functions strongly in social interactions (see Beyonce), […]...

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....

Twins Versus Siblings, Where’s The Line?

by Mark Lasbury in As Many Exceptions As Rules

What makes two babies twins? Do they have to look similar; be born at the same time; be conceived at the same time? Twins of different races give us idea just how genetics can play out in siblings and how complex the control of skin pigmentation, hair and eye color and hair texture can be.... Read more »
