Using Apple Vision Pro during surgery 16.03.2024

The medical team at Cromwell Hospital in London used Apple Vision Pro for the first time during two spinal surgeries. This event confirms the headset's potential as a medical tool that will change the way surgical practice is performed. Although the doctors themselves did not use Vision Pro, the operating room nurse worked with virtual reality using glasses while preparing and performing procedures. The headset made it possible to view virtual screens in the operating room, select instruments and monitor the progress of the operation. Software developed by eXeX, a company that specializes in creating artificial intelligence-based applications for surgery, has significantly improved the patient care process. Using Apple Vision Pro opens up new opportunities for developing healthcare applications such as clinical education, surgical planning, training and medical imaging. Implementation of Apple Vision Pro in the medical industry ... >>

Carbon storage in the North Sea 16.03.2024

Norwegian Energy Minister Terje Åsland has announced the launch of the Longship project, which aims to create a central carbon dioxide storage facility in the North Sea. This ambitious project is valued at $2,6 billion and aims to apply CCS (carbon capture and storage) technology to mitigate the impact of climate change. Norway already has experience in CCS, thanks to the successful Sleipner and Snohvit projects, and is now looking to increase the amount of carbon sealed beneath the seabed. Longship's plan calls for capacity to capture and store 1,5 million tons of carbon annually over 25 years. Despite the positive outlook, there are concerns about the long-term consequences of such storage. However, proponents of the project argue that offshore carbon storage has a number of advantages, including minimal environmental impact. The Longship project is carried out with the participation of Equinor, Shell and TotalEnergies through the joint venture Northern Li ... >>

Mini-organs grown from human amniotic fluid 15.03.2024

An international team of scientists led by Professor Fan Xiulin from Zhejiang University has developed a unique method of growing mini-organs from cells found in human amniotic fluid. This significant medical breakthrough could lead to improved diagnosis and treatment of congenital diseases. The organoids, which are three-dimensional cellular structures that mimic organs on a smaller scale, were grown from lung, kidney and small intestine cells found in amniotic fluid. This method opens up new possibilities for studying various fetal conditions and may be the key to early diagnosis and treatment of birth defects. Although no treatment has yet been attempted, the scientists hope their research will help combat the serious congenital diseases that affect millions of newborns each year. This breakthrough could change medical interventions by making it possible to diagnose and treat congenital diseases. ... >>

Not only the sun is to blame for global warming 17.11.2013

Solar activity plays a minimal role in global warming - studies by scientists from the universities of Lancaster and Durham show. Changes in solar activity are responsible for no more than 10% of global warming in the XNUMXth century.

Some scientists believe that global warming is not caused by the activities of mankind, but by the change in the amount of energy that the Earth receives from the Sun. There is a hypothesis that cosmic rays play a role in the cooling of the Earth, helping to form clouds that reflect the sun's rays into space and thus cool the planet. According to the hypothesis, during periods of high solar activity, part of the cosmic rays entering the Earth's atmosphere is blocked. Because of this, fewer clouds form and global temperatures rise.

However, in a recent study, scientists concluded that neither changes in the Sun's activity nor its effect on cosmic ray blocking could have a significant impact on global warming. Scientists have analyzed data on solar activity and global temperatures since 1955. The researchers found little correlation between 22-year solar activity cycles and global temperature increases, but the difference between flares and temperature increases is 1-2 years, and most likely the temperature change is due to the direct influence of the Sun, and not the blocking of cosmic rays. In general, the contribution of changes in solar activity, either directly or through cosmic rays, could not have been more than 10% of global warming in the XNUMXth century.

The scientists also concluded that the paleontological evidence obtained by analyzing carbon and oxygen isotopes was "weak and confusing." In addition, the studies linking cosmic ray blocking to low cloud cover only covered certain regions, not the entire planet. The researchers also did not find evidence of the "guilt" of the Sun in global warming and in the study of CERN experiments, where they are trying to simulate the processes in which cosmic rays can ionize aerosols in the atmosphere. Neither these experiments, nor real large-scale cases of atmospheric ionization, such as the accident at the Chernobyl nuclear power plant, indicate a connection with changes in the effect of cosmic radiation on cloudiness.

Thus, the attempt to "shift the blame" for global warming on the Sun has no scientific basis. The hypothesis that solar activity indirectly reduces the amount of clouds is not confirmed, and other causes of warming, other than human activity, are rather difficult to find.
