The work, published today in Nature, marks a significant step forward in our ability to study how the human body takes shape during early development.

The notochord, a rod-shaped tissue, is a crucial part of the scaffold of the developing body. It is a defining feature of all animals with backbones and plays a critical role in organising the tissue in the developing embryo.

There might not be a mysterious ‘dark’ force accelerating the expansion of the Universe after all. The truth could be much stranger – bubbles of space where time passes at drastically different rates.

The passage of time isn’t as constant as our experience with it suggests. Areas of higher gravity experience a slower pace of time compared with areas where gravity is weaker, a fact that could have some pretty major implications on how we compare rates of cosmic expansion according to a recently developed model called timescape cosmology.

Discrepancies in how fast time passes in different regions of the Universe could add up to billions of years, giving some places more time to expand than others. When we look at distant objects through these time-warping bubbles, it could create the illusion that the expansion of the Universe is accelerating.

A sequence of stress signals among specialized clean-up cells in the brain could at last reveal why some immune responses can cause significant nerve degeneration that results in the loss of memory, judgement, and awareness behind Alzheimer’s disease.

Blocking this pathway in mouse brains modeled on Alzheimer’s prevented damage to their synapse connections and reduced the buildup of potentially toxic tau proteins – both hallmarks of the condition.

The researchers, led by a team from the City University of New York (CUNY), believe this pathway – called the integrated stress response (ISR) – causes brain immune cells called microglia to go ‘dark’ and start damaging rather than benefiting the brain.

A blood test that can predict how long vaccine immunity will last so people can get a booster jab earlier, is being developed by scientists.

Researchers have previously been unable to predict why some vaccines produce antibodies to fight infections that last for decades while in others immunity only lasts a few months.
