Molecules in larvae’s food determine whether honeybees are queens or workers Plant microRNA plays a key role in determining whether a female honeybee develops into a queen or a sterile worker. The tiny molecules are present in bee bread, a mixture of pollen and honey that is fed to larvae that become workers, and they […]
I am sure that all of you have had table conversations about the flavour of tomato fruits: “These tomatoes have no taste” complained the little boy; “When I was a child tomatoes were much better, now they are tasteless” said the grandmother; “The ones I grow in my backyard are hundred times better” stated the […]

Gut microbes change seasonally in Tanzania’s Hadza people The gut microbes of a tribe of hunter-gatherers in Tanzania change along with the seasons. Researchers collected stool samples from the Hadza and found that not only is their gut microbiome diverse, it changes along with the Hadza diet, which consists of meat and tubers during the […]
In science, for a phenomenon to be reliable, it needs to be validated by a certain statistical value, the p-value, which by giving an estimate of the probability that the result would be the product of chance, serves as a measure of the probability that a certain event happening is true. So far, the convention […]
The OECD report on obesity in Spain published in 2014 (PDF) presented worrying data: 1-in-6 adults is obese and more than half are overweight, including obesity.

Cloud bands like those around Neptune observed on brown dwarfs Cloud bands similar to those around Neptune have been detected surrounding brown dwarfs, massive objects that aren’t quite planets and didn’t make the cut as stars. This is the first time cloud bands have been found in brown dwarf atmospheres. Space.com Stimulating perirhinal cortex causes […]
Like father like son. We have all heard it one time or another. The layman explanation to hereditary characters. Whether the cause is genetic inheritance or the effect of growing up in a certain environment, is quite something else. When talking about the origin of intelligence, there are always discussions. Even though there is undoubtedly […]
Specialized media sometimes publishes similar headlines to the title of the present article. For instance 1, 2, 3, 4, 5 or 6. They are all referred to deep learning, which is a part of artificial intelligence. However, if we get algorithms to work and achieve advanced intelligent applications, what is exactly not understandable? Deep learning […]
CRISPR edits genes in pigs to make organs safer for transplants Researchers have inactivated porcine endogenous retroviruses using CRISPR-Cas9, paving the way for potentially safer pig-to-human transplants. After 25 retroviruses were edited out of the pig DNA, the genetic material was added to pig eggs, which were implanted in sows who gave birth to piglets […]
