Most of us don’t know too much about the female eggs – it’s a shame that we know more facts about the eggs in a carton than these eggs. Here are some interesting facts about the female eggs:

1. They are made quite early. The female reproductive system makes the eggs about nine weeks after conception. Then, the ovary produces about 7 million oocytes (female gametocytes involved in reproduction) in only 5 months. Until birth, most of the immature egg cells die off.

2. The eggs are huge! If you compare the egg cells with other body cells, you will see that there is a huge difference in size. The female eggs have a diameter of 100 microns, and are thick as a strand of hair.

3. They are precious. A woman ovulates about 400-500 eggs during her lifetime, making the eggs more precious and rarer than sperm. A single ejaculation releases more sperms than a woman produces eggs in her lifetime! That’s why there are egg donors that cost hundreds of dollars for just one egg.

4. The eggs have extended adolescence. The egg cells grow-up slow – they need years to reach adolescence, and mature right before ovulation.

5. They are quite fragile. As the female eggs are fragile, a technique called vitrification can harden their outer layer and make them more resilient.

Quick rise in young people with Type 2 diabetes is alarming

Hundreds of young people are being treated for Type 2 diabetes, a 41% rise in just four years.

The condition occurs when the body cannot make enough insulin to regulate blood sugar levels.

It is often linked to obesity and is most commonly seen in adults, where it can lead to a range of health problems such as heart disease and strokes.

Some 715 people under the age of 25 received treatment for the disease in England and Wales during 2016/17 and 78.6% of them were obese.

The number of cases is up from the 507 registered in 2013/14, according to the Royal College of Paediatrics and Child Health.

But the true number may be much higher, as the RCPCH recorded only those young people being treated in paediatric units, not by a GP.

Professor Russell Viner, president of the RCPCH, said: “A rise in Type 2 diabetes of this magnitude is alarming and shows that the childhood obesity epidemic is starting to bite.

“It’s also concerning that we might not be seeing the full picture.”

The Local Government Association, which represents 370 councils in England and Wales, said more support was needed, especially for obese children and ethnic minorities, as almost half of those treated in 2016/17 were black or Asian.

Izzi Seccombe, chairwoman of the LGA’s community wellbeing board, said: “These figures are a sad indictment of how we have collectively failed as a society to tackle childhood obesity, one of the biggest health challenges we face.”

She called for “urgent action”, saying: “Type 2 diabetes can be a lifelong debilitating illness and these figures will only multiply if we delay.

In an experiment, the researchers demonstrated that it is possible to more than double the amount of time, from the clinical standard approach, that red blood cells can be stored. At present, red blood cells can be stored for a maximum of 42 days. Using this new approach, it was possible to extend this up to 100 days.

Alongside the immediate practical applications, the researchers also believe that this discovery could enable fundamental scientific research by making it possible to study liquid phase reactions at a much lower temperature than is currently possible.

Heck, who knows — although this approach studiously avoids actual freezing, maybe it could prompt advances in the kind of long-term cryogenic preservation process that scientists, sci-fi authors, and, allegedly, Walt Disney have speculated about for years.

“We are now focused on increasing the volume of the preserved liquid phase from the 1-100 milliliter range to 500 milliliters to enable mass preservation of samples,” Usta continued. “[We also want to translate] our approach to the preservation of exotic cell types and organs, such as the liver, since our center already has a very active cell and organ preservation research thrust. Through collaborations, we are also looking into further understanding our observations by conducting [additional] computational and laboratory experiments.”

A paper describing the work was recently published in the journal Nature Communications.
