Manicured lawns are dangerous

10.11.2023

Ideal lawns, although aesthetically pleasing, can have a negative impact on the environment. Paying special attention to nitrogen fertilizer management and implementing greener lawn care practices can mitigate negative impacts and provide a more sustainable balance between aesthetics and ecology.

Grass lawns, neat and well maintained, occupy a large part of residential areas, providing people not only with visual pleasure, but also with health and well-being benefits. However, a new study conducted by scientists from New York University reveals that behind this idyll lie potential threats to the environment.

Scientists, after analyzing data from numerous surveys in the United States, found that about half of homeowners use fertilizers on their lawns, while many of them are not aware of the negative effects of nitrogen fertilizers. The study highlights that nitrogen from fertilizers can leach into water resources, causing problems for the ecosystem, including the formation of algal blooms and loss of oxygen in the water. Scientists have previously warned against excess nitrogen pollution, noting its negative consequences for human health and climate change.

During the study, scientists identified “hot spots” with the greatest nitrogen loss and determined time periods during which peak nitrogen discharge occurs. By analyzing three lawns in the Baltimore area, the scientists found that areas of high nitrogen loss corresponded to areas of lawn fertilizer use.

Researchers suggest that replacing just 5-10% of lawns maintained with chemical fertilizers can have a significant impact on nitrogen removal rates. As an alternative, they suggest using fall leaves as a natural mulch, eliminating the need for nitrogen fertilizer.

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 ... >>

US space exploration 08.10.2021

The US Space Force has established an intelligence analysis team at the National Air and Space Intelligence Center at Wright-Patterson Air Force Base, Ohio.

The structure, called the Space Force Intelligence Activity (SFIA), will become an intermediate step towards the creation of a full-fledged Space Intelligence Center.

A memorandum to this effect was signed by Major General Leah Lauderbuck and Lieutenant General Mary O'Brien. Lauderbuck is the head of the Intelligence, Surveillance and Intelligence Service of the Space Force. O'Brien is the USAF Deputy Chief of Staff for Intelligence, Surveillance, and Cyber Effects Operations.

The organization will be staffed by teams of space and counterspace analysts who are based at the National Aerospace Intelligence Center (NASIC) and will move to the National Space Intelligence Center.

NASIC is the Pentagon's primary source of information on threats affecting air and space operations. The space and counterspace analysis groups include both military and civilian personnel.
