When were the first animal protection laws passed?

Over 2000 years ago. The Indian emperor Ashoka, a staunch Buddhist, ordered the establishment of animal shelters throughout the country.

The first such laws in Europe were passed in England in 1822. True, they concerned only horses and livestock.

What did Galileo Galilei see through the telescope?

In 1609, Galileo learned that a far-seeing device had appeared in Holland (this is how the word "telescope" is translated from Greek). The basis of this device is a combination of optical glasses. He collected several telescopes, each subsequent one gave an increasing increase, and if the first magnified only 3,5 times, then the best of the Galilean telescopes gave an increase of 33 times. Galileo made great discoveries with these homemade instruments.

The moon is not an ethereal luminary of light gases, but a planet similar to the Earth, with vast plains and mountains, the height of which Galileo determined by the length of the shadow they cast.
Observing the Sun (Galileo put smoked glass to the lens), the scientist discovered spots that move. Giordano Bruno's guess was confirmed: the Sun rotates around its axis, just like the Earth.

Through a telescope, Jupiter is seen not alone, but with four satellites that revolve around it, as if it were a miniature solar system. The Milky Way, a nebulous streak that crosses the sky, is seen through a telescope as crumbling into countless stars.

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 ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

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. ... >>

Protein hydrogel for drug delivery 28.09.2019

A team of scientists from the Tandon School of Engineering at New York University (USA) has created the first biocompatible protein-based drug delivery system that is so durable that it can live in the body for more than two weeks and is able to provide a sustained release of drugs. This hydrogel is an important step for the future of drug delivery, tissue engineering and regenerative medicine.

Hydrogels are three-dimensional polymeric networks that turn from solution to gel in response to physical or chemical influences, such as temperature or an acidic environment. In these polymer matrices, like in a capsule, loads such as small molecules can be placed. The new hydrogel consists of one protein domain (section of the protein polypeptide chain) and passes from solution to gel at low temperatures. It exhibits many of the same properties as a synthetic hydrogel. Its main advantage is biocompatibility, so it is best used in biomedicine.

In their experiment, the scientists placed a curcumin molecule in a hydrogel. They found that the hydrogel is stabilized by the molecular entanglement of protein nanofibers, creating a porous matrix capable of binding a small molecule that is afraid of water. Together with this molecule, the entanglement of the fibers increases, which ensures the mechanical integrity and thermal stability of the hydrogel. Due to this, the hydrogel, when it enters the human body, is destroyed more slowly, and the drug is released longer.

Going forward, the researchers will try to develop protein hydrogels that can respond to specific temperatures for various drug delivery applications.
