That female fertility is not stable during a woman’s lifetime is nothing new, but now a new study in the journal Science has found an explanation to its inverted U shape: chromosome errors! This inverted U shape for female fertility means that adolescent women and women over their mid-30s are not as fertile as those […]
After the big scandal of the CRISPR babies at the end of 2018, some might have thought that would be the end of CRISPR in the clinic, but luckily that has not been the case and despite the public outrage of last year, today we can report on its successful use as gene therapy against […]
Good news everyone! A newly discovered type of hepatic cell might hold the key to repair all those old fatty livers without needing a transplant. And not only those but also those of people suffering from side effects of medication, cancer etc etc But let’s try not to get ahead of ourselves. A team of […]
As one of those people who REALLY love to sleep -and doesn’t get close to enough of it- I am always interested to read on the topic. What I didn’t expect was to read about sleeping fish and how that relates to its origin . But let’s get down to the details, because if the […]
First of all, I don’t want to mean that a neuron was found in space, but that similarly to the grid cells found by Nobel laureate May-Britt Moser and colleagues another cell type named object-vector cell has been found -also by their group- which is involved in spatial sensation. While grid cells are place modulated […]
Recently, the journal Science showed in its cover an amazing image of a close up into the fly brain. This is the result of the combined effort of two research groups working on imaging. The first one (Boyden’s) had developed a way to increase the size of preserved samples, like a brain slice, up to […]
Recent research by a collaborative research network including researchers in Spain and the UK has found 25 genes that seem to be responsible for making humans the primates with the longest life spans (sometimes going up to 120 years). These genes show parallel mutations in genes related to wound healing, blood coagulation and cardiovascular disorders […]
If there is one worrisome fact about science here and now, it is this: the possibility that a huge amount of publications is to be retracted due to falsified or duplicated data. The phenomenon is not new, there have been more than a few reports sounding the alarm on precisely this problem, and there is […]
While I was at school it was almost a dogma that you’d not get a neuron more than those you were born with. Later, at university we learned that actually there was a region in the human brain, namely the hippocampus (key region for memory formation) where there was indeed adult neurogenesis, that is, formation […]
A s a recent mom, I can attest to the fact that at least some humans don’t quite get enough sleep, but the thing is, independently of why my baby thinks sleep is for cowards, in a new article researchers Charles Nunn and David Charles, have shown by comparing sleep patterns of 30 species of […]
