Mary’s Monday Metazoan: Sad kiwi

This bird may be doomed. It’s genome has been sequenced, and there is very little genetic diversity in the remaining populations.

You may have seen the hype. GAME-CHANGING CURE FOR ALZHEIMER: THE NEW DRUG, NEW BREAKTHROUGH. Next Best Thing To Alzheimer’s Cure: Solanezumab May Delay Onset Of Dementia By 30%. Have scientists found a drug to stop Alzheimer’s disease? I’m going to have to pop your balloon. Someone knowledgeable actually looked at the study.

I built a microscope today

I did! It was an origami microscope, with a single simple lens added. Here’s what it looks like: It’s called a Foldscope, and I got it as part of a beta test program. It’s a bit like the original Leeuwenhoek microscope, which you held up to your eye to see a magnified image.

That quote is from a good article in Nature on how sex is non-binary — my only quibble would be with that “now”. You’d have to define “now” as a window of time that encompasses the entirety of my training and work in developmental biology, and I’m getting to be kind of an old guy.…

It’s the same old story

Denialists claiming to be pro-science. Politicians insisting on a balanced treatment. A population ignorant of the science indignantly rejecting a clear and well-established, evidence-based conclusion. I’m not talking about creationism, although it’s exactly the same story.

Just yesterday, Japanese fishermen caught a 6m long giant squid, and it lived for a few hours before expiring. Here’s a video of the rare beastie swimming about, with shots of the tragic corpse afterwards.

Cancer: bad genes or bad luck?

If there is one cause of cancer, it would be genetic damage to somatic cells. So all we have to do to cure cancer is prevent all genetic damage! That’s not a very useful prescription, unfortunately; it’s rather like saying that all we have to do to prevent accidental deaths is prohibit all potential causes…

Michael Egnor, neurosurgeon, has made a bizarre post in which he reveals that he knows nothing about how the brains he cuts up work. Egnor claims that it is impossible for the brain to store memories. Yes, he knows that neural damage can cause loss of memory, that certain delicate areas of the brain, if…

The Lancet done screwed up

Chelsea Polis and Kathryn Curtis wrote a paper that asked whether hormonal contraceptives affected your likelihood of being infected with HIV, Use of hormonal contraceptives and HIV acquisition in women: a systematic review of the epidemiological evidence. Here’s the abstract: Whether or not the use of hormonal contraception affects risk of HIV acquisition is an…

Mary’s Monday Metazoan: Best name ever

It’s the Bone Eating Snot Flower Worm. As a bonus, it’s also one of those species where the large adult forms are all females, and the males have been reduced to a tiny bag of sperm attached for life to a Bone Eating Snot Flower Worm.
