“The b rain is considered an isolated tissue from the rest of the body thanks to the blood-brain-barrier, which separates it at cellular level with a very strict control”. That was supposed in the past, at least until now… In 2019 a striking discovery led by the researcher Moreno-Jimenez demonstrated human neurogenesis is abundant and […]
I know it seems like an absurd question to start with: can a foetus without egg and sperm even exist? As scientists show in a recently published article in the journal Cell , at least for mouse embryos in the lab, it is not only possible, it is a reality. These researchers used EPS, short […]
New image offers closer view of interstellar object Astronomers used the W.M. Keck Observatory’s Low-Resolution Imaging Spectrometer to take a new image of 2I/Borisov, the second interstellar object ever observed passing through our solar system. The image shows the coma of the interstellar comet, which will pass by the sun early next month and Earth […]

In 1882, Heinrich Hertz devoted himself to the study of electromagnetism, including the recent and still generally unappreciated work of Maxwell. Two years later he began his famous series of experiments with electromagnetic waves. During the course of this work, Hertz discovered the photoelectric effect, which has had a profound influence on modern physics. The […]
In great contrast to the native American persimmon, Diospyros virginiana L., which has never advanced beyond the status of a minor fruit, an oriental member of the family Ebenaceae, D. kaki L. f ., is prominent in horticulture. Perhaps best-known in America as the Japanese, or Oriental, persimmon, it is also called kaki (in Spanish […]
The question of whether it is genes or environment that largely shapes human behaviour has been debated for centuries. During the second half of the 20th century, there were two camps of scientists – each believing that nature or nurture, respectively, was exclusively at play. This view is becoming increasingly rare, as research is demonstrating […]
Clues point to possible fifth fundamental force Physicists say they’ve gathered more evidence that there could be a fifth physical force in addition to gravity, electromagnetism and a pair of nuclear interactions. The researchers say they’ve glimpsed a force carried by a particle they’ve named X17 most recently coming from a helium atom; if the […]
Scanning tunneling microscopy (STM) is a technique in which a fine conducting probe is held close to the surface of a sample. Electrons tunnel between the sample and the probe, producing an electrical signal. The probe is slowly moved across the surface and raised and lowered so as to keep the signal constant. The precision […]
Alternative facts are spreading like a virus across society. Now it seems they have even infected science – at least the quantum realm. This may seem counter intuitive. The scientific method is after all founded on the reliable notions of observation, measurement and repeatability. A fact, as established by a measurement, should be objective, such […]
One of the hardest things when dealing with psychiatric illness is to come up with a clear diagnosis, but it seems that now it might be possible to diagnose schizophrenia just by analysing a certain biomarker in people’s hair. In an article recently published in the EMBO Journal of Molecular Medicine , a Japanese group […]
