Tent for other planets

08.04.2010

The American firm ILC, which developed space suits for astronauts who walked on the moon and for American shuttle crews, is now preparing inflatable houses for the future lunar station.

A "pipe" with a diameter of three meters is stretched between two metal hemispheres, made of 12 layers of special fabrics and a metallized polymer film. The lunar dwelling is brought into place in the form of a ball, then the middle is inflated with air, and the ball turns into a tubular house for lunar explorers. Air locks and other equipment are located in the end hemispheres.

The proposed design can be used both on Mars and on Earth - in the Arctic and Antarctic.

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. ... >>

Electronic helmet for truck drivers 14.04.2024

Road safety, especially for drivers of heavy construction equipment, is a top priority for engineers and scientists. In light of this, the German Fraunhofer Institute for Structural Strength and System Reliability has introduced a new product - an electronic helmet, which is designed to protect drivers from serious injury when driving construction vehicles. A new electronic helmet developed by a team of engineers from the Fraunhofer Institute opens up new perspectives for the safety of truck and construction equipment drivers. The device is capable of monitoring the level of shaking in the car cabin and warning the driver of possible danger. The basis of the helmet's operation is a built-in piezoelectric sensor, which generates electricity during physical deformation. This mechanism allows the device to respond to intense vibrations typical of construction equipment. When the level of deformation exceeds safe values, an alarm system is activated on the helmet, ... >>

Antivitamins instead of antibiotics 13.04.2024

The problem of bacterial resistance to antibiotics is becoming increasingly serious, posing a threat to the effective treatment of infections. In light of this, researchers are looking for new ways to combat superbugs. One of the promising directions is the use of antivitamins that can have an antibacterial effect. Antivitamins, although known as the opposite of vitamins, have proven to be a promising tool in the fight against bacterial antibiotic resistance. A study conducted by scientists from the University of Göttingen in Germany confirmed their potential in creating new drugs to combat dangerous infections. With the rise of antibiotic-resistant superbugs, there is a need to find alternative treatments. Antivitamins are molecules similar to vitamins, but capable of inhibiting bacterial activity without harm to the human body. At the moment, science knows only three antivitamins: rose ... >>

human body simulator 30.01.2020

Scientists from the Wyss Institute of Bionics at Harvard University have created a human body simulator from 10 connected organs. The proposed Body-on-Chips platform (a body on a chip) goes beyond simple imitation of organs and makes it possible to track the effects of medicines on the human body in a complex, and not just on its individual parts.

Such a platform will significantly accelerate the development of new drugs, especially in the early stages of drug trials. The beneficial effect of a chemical on one organ may cause side effects in others, as indicated by the "body on a chip", but not the "organ on a chip". Also, the developed system makes it possible to select the desired concentration of the drug and evaluate the rate of its removal from the body. In other words, the Body-on-Chips platform allows you to track both pharmacokinetics (PK, absorption, distribution, metabolism and excretion) and pharmacodynamics (PD, effects, mechanisms and side effects).

Structurally, the body-on-a-chip is a series of interconnected devices the size of a memory card. Every organ? these are two parallel channels, one of which imitates or contains specific tissues of a certain organ, and the second, adjacent, imitates blood vessels. Both channels are separated by a porous membrane specific to this organ. In the body model, all "organs" and blood vessels are connected by microtubes that mimic the circulation of blood in the human body. All this is controlled by commands from the computer.

The scientists successively connected the vascular channels of eight different organ chips, including the intestine, liver, kidney, heart, lung, skin, blood-brain barrier, and brain. The device was able to maintain the viability of all tissues on the chips for three weeks. Experiments with the distribution of nicotine in the "organs" and the impact on them of one of the drugs for chemotherapy showed that the content of substances in the "organs", their negative effect on tissues, the concentration and rate of excretion from the artificial organism are almost the same as in the case of taking a living person. It would not be an exaggeration to say that this will change the world of pharmaceuticals and humans for the foreseeable future.
