Algae as food for livestock

16.10.2021

Swedish cows will be given seaweed as a dietary supplement. Thanks to such a diet, methane will no longer be produced in the stomachs of cows, a gas whose greenhouse effect far exceeds the effect on the atmosphere of carbon dioxide.

According to Swedish scientists, if cows eat an additional 100 grams of seaweed daily, the amount of methane emissions from them will decrease by 80%.

Seaweed will be grown in a factory that will be built specifically for this purpose. The algae will be grown in laboratories and then dried and pressed into portioned containers.

Cows are responsible for 4% of the world's methane emissions. This is twice the performance of the aviation industry.

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Implanted brain stimulator 30.04.2024

In recent years, scientific research in the field of neurotechnology has made enormous progress, opening new horizons for the treatment of various psychiatric and neurological disorders. One of the significant achievements was the creation of the smallest implanted brain stimulator, presented by a laboratory at Rice University. Called Digitally Programmable Over-brain Therapeutic (DOT), this innovative device promises to revolutionize treatments by providing more autonomy and accessibility to patients. The implant, developed in collaboration with Motif Neurotech and clinicians, introduces an innovative approach to brain stimulation. It is powered through an external transmitter using magnetoelectric power transfer, eliminating the need for wires and large batteries typical of existing technologies. This makes the procedure less invasive and provides more opportunities to improve patients' quality of life. In addition to its use in treatment, resist ... >>

The perception of time depends on what one is looking at 29.04.2024

Research in the field of the psychology of time continues to surprise us with its results. Recent discoveries by scientists from George Mason University (USA) turned out to be quite remarkable: they discovered that what we look at can greatly influence our sense of time. During the experiment, 52 participants took a series of tests, estimating the duration of viewing various images. The results were surprising: the size and detail of the images had a significant impact on the perception of time. Larger, less cluttered scenes created the illusion of time slowing down, while smaller, busier images gave the feeling of time speeding up. Researchers suggest that visual clutter or detail overload can make it difficult to perceive the world around us, which in turn can lead to faster perception of time. Thus, it was shown that our perception of time is closely related to what we look at. Larger and smaller ... >>

A new organ found in the human body 07.04.2018

A group of American scientists led by Professor Neil Theise of New York University discovered a new organ in the human body, the detection of which has so far been hampered by the limitations of the standard technique.

The new organ is a branched system of interconnected cavities in the connective tissue that permeates the entire body. The walls of these cavities are made up of cells that look like fibroblasts and contain fibers of strong collagen and elastin proteins. The cavities themselves are filled with fluid and open into the lymph nodes.

The cavities included in this system are found under the skin, as well as in the "lining" of many muscular organs: the gastrointestinal tract, bladder, lungs, and blood vessels. Scientists believe that the newly discovered organ acts as a "shock absorber", protecting muscle tissue from damage during contraction and relaxation.

However, its role in the work of our body, apparently, does not end there. It seems that these cavities are also involved in the formation of edema and fibrosis; in addition, metastases of cancerous tumors and the substances that feed them spread through them. For the first time, scientists saw them when examining the bile ducts of a cancer patient.

The new organ was called "interstitium" (interstitium).

Why was this discovery not made earlier? The fact is that the standard method of histological examination (i.e., the study of body tissues) is based on fixing them with special chemicals and dividing them into thin sections, which are examined under a microscope. At the same time, the liquid flows out of the cavities and they become invisible.

However, Teise and colleagues used a different approach: they injected a fluorescent dye into the patient's living tissues, illuminated them with a laser, and inserted an endoscope into the patient's body. As a result, the interstitium was examined in detail.
