#zrodlo

In the largest study of its kind, five new malaria vaccine targets have been discovered. Researchers studied the malaria parasite at its most vulnerable stage -- when invading human red blood cells -- and identified five targets that lead to a reduction in the parasite's ability to enter red blood cells.

Even low levels of logging in the Amazon rainforest may lead to great losses in biodiversity, new research has found. The research looked at 34 different plots in the state of Pará -- a focal point for Amazon protection efforts in the last decades. They found that even low levels of logging leaded to negative effects on dung beetle diversity and rates of dung beetle-mediated

#zrodlo

A new study offers a rare glimpse into the genetics of a herpes simplex virus transmission event -- information that may prove useful in future development of therapeutics and vaccines. The study reveals nearly perfect genetic transmission of the virus from a father to his son and lays the foundation for future studies exploring the genetic diversity of this virus.

Immune response: Scientists identify 'first responders' to bacterial invasion

When bacteria enter our body, they kick-start a powerful immune response. But this chain of reactions doesn't fully account for our immediate responses. Researchers show that so-called ion channels play a key role as 'first responders'.

Scientists with the VaquitaCPR conservation project announced they succeeded in locating and rescuing a highly endangered vaquita porpoise yesterday, but in an abundance of caution the vaquita, which was a calf, was released. VaquitaCPR is trying to save the world's most endangered marine mammal. Less than 30 are left in the world.

#zrodlo

Two recent studies provide significant new hope in the fight against antibiotic resistance. By identifying what makes some bacteria resistant to the most commonly prescribed antibiotics, and how this can be reversed, the findings have demonstrated potentially life-saving consequences and could help reverse the tide of antibiotic resistance.

#zrodlo

Researchers have conducted a novel transdisciplinary study to characterize the microbial communities within the vascular system of grapevines and their connections with Pierce's disease, an economically significant disease of the California grape industry. Through the study, the researchers found potentially beneficial microbes that could one day be used as a deterrent to Xylella fastidiosa, the pathogen that causes Pierce's disease.

A new study based on the first global survey of marine life by scuba divers has provided fresh insights into how climate change is affecting the distribution of marine life. The research predicts that as the oceans warm fish -- which appear to be superior predators in warm water -- will extend their ranges away from the equator and cause a decline in the diversity of invertebrates such as crabs, lobsters, sea urchins and whelks.

When teeth grow on the body

Added: 20.10.2017 17:27 | 0 views | 0 comments

#zrodlo

Today, certain species of catfish are covered with bony plates bristling with thin teeth, like some extinct vertebrate lineages. These teeth, which regularly fall out and then grow back, are used for defense and, in males, also to seduce the females. Researchers wanted to understand how these teeth capable of regeneration can develop outside of the mouth. They discovered that the extra-oral teeth always grow on a bone, regardless of its type, even in the absence of a bony plate. This suggests a role for bone in the induction of dental tissue. These results help to elucidate the mechanisms allowing the formation and regeneration of teeth in all vertebrates, including in humans.
