Orangutans are near extinction

Orangutans are the largest tree-dwelling mammals and the last remaining great apes in Asia. These primates with reddish brown plumage are common in rooms of Sumatra and Borneo. But they are increasingly threatened by the decline of rainforests and other human activities. In addition, poaching poses a great danger. And unfortunately, intensive measures are not …

New dinosaur species found in Mexico

Paleontologists have found a previously unknown dinosaur species in Mexico. The herbivorous Tlatolophus galorum could be identified thanks to the fairly well preserved skull (80%). The skull, which was found during excavations in the state of Coahuila in northern Mexico, also has a 1.32-meter crest on it. The name Tlatolophus is derived from the Aztec …

There are 50 billion birds in the world. Sparrow population first

  With a pair of binoculars, a camera, and a little patience, many people around the world spend their free time in nature to watch birds. Widespread in England since the 18th century, this hobby has become a global trend in recent years. Thanks to digitization, observations are now systematically recorded. Bird researchers now have …

How did piranhas acquire the ability to “sing”?

Most fish deliberately make special sounds to find mates, emit warning signals, protect habitat, or keep the flock together. Others sing with their swim bladders, which is also true for red-bellied piranhas (Pygocentrus nattereri). The red-bellied piranha is the research object of Boris Chagnaud of the University of Graz. The researcher has been studying predatory …

The body rests, the brain does not!

In brain imaging studies conducted with many participants in different parts of the world, it was found that individuals actively use certain brain regions when they are left alone, awake and at rest (1,2). It has been observed that the brain regions activated at that time are the same in most people, regardless of the …

Are you right-brained or left-brained?

Those seeking the answer to this popular question in neuroscience will likely be disappointed. Recent research shows that people use both halves of their brains with similar intensity. According to the general opinion, the left brain is more creative and artistic, while the right brain is more organized and logical. When you search for the …

Neurons related to maternal instinct found

In the animal world, mothers take great risks to protect their young. Japanese scientists who conducted experiments with mice found that the maternal instinct is at least partially related to certain nerve cells in the forebrain. Kumi Kuroda of the Riken Center for Brain Research sums up the findings, ‘we were able to separate neurons …

Mice smarter with human gene

We humans have a very large brain compared to our body. The greater cerebral cortex (neocortex) is more developed in our species than in any other primate. The increase in volume in the large cerebral cortex (cerebral cortex) and small brain (cereblral cortex) is the basis of our intelligence. This naturally raises the question of …

What happens in the brain when sneezing?

Working with Fengxian Li at the University of Washington, the team investigated what triggers a sneeze and how the reflex can be prevented. If we find out how neurons react to allergens and viruses, we can slow down infectious respiratory diseases spread by sneezing, says Li’s colleague Qin Liu. In order to study the neuronal …
