Today in biology the teacher asked “why do chromosomes have to stick together?” And I whispered “because they’re bromosomes” and the guy next to me just about died laughing

New Technology Shows Nurses Where Your Veins Are

If you are a human (if you’re reading this article, you probably are), at some point in your life, you’ll probably have give blood. It could be a blood donation meant to help the sick, or it might just be a sample that is being taken in order to do some necessary testing. Regardless of the reason, you’ll probably have a slightly uncomfortable experience as the nurse struggles to locate your vein.

It’s something that many people have been through.

The ordeal usually ends with the nurse stating that your veins are “really hard to find,” and moving on to prodding your other arm. Fortunately, a new device could prevent this from ever happening again, making the process a lot easier on both the patient and the nurse.

Scientists recently developed a device that casts a harmless near-infrared light at your arm, making our veins visible. This technology works because our veins contain a lot of deoxygenated haemoglobin, which is absorbed by infrared light. This absorption allows us to see an image of exactly where your veins are under the skin.

The Australian Red Cross is the first blood bank services in the world to start testing this technology. It is already in use in clinics that are located in Sydney. Perhaps best of all, this device can be used anywhere, including in hospitals and pathology clinics.

50 species of lizard and one species of snake reproduce through parthenogenesis (that’s the fancy word for producing offspring as a female without having sex).

Except.

Whiptails are stimulation ovulators. That is to say, they can’t ovulate without having sex.

So not only do they are give birth through immaculate conception, they’re ALL LESBIANS.

There are two kinds of parthenogenesis seen in reptiles. That used by whiptails and the other all female species is true cloning - the egg contains the female’s full genetic material).

Other species including komodo dragons use another form of parthenogenesis where they actually fertilize themselves, with a haploid polar body used instead of a sperm. Because of the way reptile sex chromosomes work, this form of parthenogenesis can produce males as well as females - however, the females produced have weird sex chromosomes and can only lay other females. It’s used as a backup reproductive strategy if they can’t find a mate. This works because in reptiles, unlike mammals, its the males that have two sex chromosomes the same (ZZ) and the females different (ZW). Females produced by parthenogenesis are WW - and that’s what happened to the whiptails. They lost the Z chromosome and now are all WWs.

IOW?

Reptiles are fascinating.

"why are these scientists talking about pluto when they should be curing ebola" because they’re astrophysicists not molecular engineers or infectious disease specialists you’re getting mad at the wrong people
