Tumor Killer Viruses

Tumor Killer Viruses

Biomedicine

By Marisa Alonso Núñez

Killing cancer cells is a key point to cure cancer. Many researchers are working on developing different therapies to do just that. The one I’m going to talk about today is a very promising one: Oncolytic Virotherapy. Just the name may scare you but it’s a very clever approach to treat some tumors lacking a […]

Sesame Street and brain activity in children

Neuroscience

By César Tomé

In the real world, children learn new information by participating in classrooms, interacting with their family and friends, and watching educational videos. While previous neuroimaging research has typically used simple tasks and short-lasting stimuli, in a new study published in PloS Biology researchers examined brain development using a more complex and naturalistic educational stimulus. Children […]

First brain cells found devoted to selective attention in an invertebrate animal. Dragonflies lack humans’ big brains, but they still get the job done, according to new research that suggests that these insects have brain cells capable of feats previously seen only in primates. Specifically, the dragonflies can screen out useless visual information to focus […]

Astrophysics

By Francisco R. Villatoro

Newton’s theory of gravitation assumes that the speed of gravity is infinite and the gravitational interaction is instantaneous. However, Einstein’s theory postulates that it is exactly equal to the speed of light. A team of Chinese physicists lead by Tang Ke Yun, at the Institute of Geology and Geophysics, Chinese Academy of Sciences, Beijing, China […]

The advances in molecular biology and the so called post-genomic era, have improved significantly the fight against many human diseases, in some cases almost leading to their eradication. However, there are still regions of our planet were people suffer from infections and other causes of mortality which are easily avoided in the most developed countries […]

From the genetic point of view, when should a man be more interested in caring for his sister’s children than his wife’s? A quantitative analysis of Alan Rogers, University of Utah, shows that this behaviour should be the choice in populations where adultery is common or permitted. In the animal world, males caring for offspring […]

Smelling the taste

Smelling the taste

Neuroscience

By Moisés García-Arencibia

When animals eat, both the olfactory (odour) and gustatory (taste) systems send information to the brain about the food being eaten. This combined information is very valuable to determine whether the animal is about to swallow something poisonous or something nutritious. That odours can influence the processing of taste is well known, and most people […]
