How were antibiotics discovered?

Antibiotics were discovered by accident. Alexander Fleming left a vial of staphylococcus bacteria unattended for several days. Due to the usual disorder for his laboratory, a colony of mold fungi grew in a test tube and began to destroy bacteria, and then Fleming isolated the active substance - penicillin.

Authors: Jimmy Wales, Larry Sanger

Whose cubs during childbirth fall to the ground from a height of two meters?

During childbirth, a female giraffe does not lie on the ground, so a newborn giraffe has to fall from a height of two meters at the first moment of life. True, this does not injure him: at the time of childbirth, his height is already approaching two meters, and his weight is 50 kg.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Tasmanian Devil's Milk Contains Powerful Antibiotics 25.10.2016

Scientists from the University of Sydney (Australia) have synthesized a protein that mimics the milk protein of the Tasmanian devil, which has antibiotic properties. At the same time, the substance is active even against bacteria that are resistant to traditional antibiotics.

The study showed that the substance copes with such pathogens of dangerous infections as Staphylococcus aureus and Enterococcus aureus. This protein, the structure of which scientists "peeped" from the Australian marsupial, was named cathelycidin.

Interest in the Tasmanian devil is due to the fact that these animals successfully carry young in bags, despite an unsafe environment with a lot of bacteria. Since the immune system of these animals is quite primitive, scientists began to look for an answer in a different direction. And they found it by studying the characteristics of the milk of a female Tasmanian devil. It turned out that a special protein found in milk is absent in other mammals or is present, but in small quantities.

The authors of the study hope that their discovery will allow the creation of new drugs that are effective against the so-called superbugs that do not respond to existing antibiotics. The problem of antibiotic resistance has been rapidly exacerbated in recent decades; according to WHO estimates, about 700 patients per year die from diseases caused by such bacteria, and this figure is constantly growing.
