    Deltacron”, a new variant of coronavirus, has been detected in Cyprus

    A new variant of coronavirus SARS-CoV-2, a hybrid version of Delta and Omicron strains, has been discovered in Cyprus. Dubbed as “Deltacron”, the new variant bears the genetic basis of Delta, along with some mutations specific to Omicron strain.

    The new strain was named by Leondios Kostrikis, a professor of biological sciences at the University of Cyprus, writes Bloomberg.

    Deltacron was identified in 25 samples taken in Cyprus, of which 11 came from people hospitalized and 14 from the general population.

    The frequency of mutations was higher among those in the hospital, which could suggest that there is a correlation between Deltacron and hospitalizations, Cypriot officials say.

    The researchers sent forth the information to an international database.

    Deltacron variant emerged while Omicron is spreading rapidly throughout the world leading to an accelerated increase in the number of infections.

    In the US, Omicron pushed COVID hospitalizations to record highs. According to Reuters, there are now more people being treated in medical centers than in January last year, when more than 132,000 hospitalizations were recorded.

    Health care officials in the United States reported more than a million cases of Covid19 infections in a single day early this week and later on more than 800,000 people were confirmed with the disease on a daily basis.

    Perseverance, which conveys a 2-meter long robotic arm, 19 cameras and two microphones was launched on July 30, 2020. If it survives the touchdown, it will be the fifth NASA rover that manages to reach Mars in the past 24 years. Curiosity, which arrived in 2012, is still performing various scientific measurements on the site.

    So far, Perseverance has traveled over 470 million km with less than 7 million km left to the Red Planet. The spacecraft currently moves at a speed of 77,000 km/h

  • First anti-corona drugs tested on humans. Remdesivir, a potential solution for fighting COVID-19

    First anti-corona drugs tested on humans. Remdesivir, a potential solution for fighting COVID-19

    Although a vaccine against COVID-19 may take at least another year to come, research into medicines and antivirals may provide a solution. Two have the most encouraging results in laboratories, and the first tests on humans have already begun. Can we already cheer or is it still too early for that?

    Coronavirus

    One of those experimental agents, which will become available for seriously ill corona patients, is the virus inhibitor Remdesivir. The drug was originally developed as an anti-Ebola drug, but it was dropped because other medications were found to work better against this disease. Remdesivir may still play an important role in the fight against the COVID-19 virus.

    As of this week, Dutch hospitals can apply for aquisition of Remdesivir from the American manufacturer Gilead. For the time being, physicians should only administer the drug to critically ill corona patients who are on respiration and whose organs have not yet failed.

    80 Percent Of Dutch Coronavirus Intensive Care Patients Are Overweight

    80 percent of the Dutch corona patients treated in intensive care units (ICU) are overweight, Diederik Gommers, chairman of the Dutch Association for Intensive Care (NVIC), said during the television program Jinek on Friday.

    SARS-CoV-2 coronavirus

    According to Gommers and Peter van der Voort, head of intensive care at the University Medical Center Groningen (UMCG), there is “apparently” a link between obesity and COVID-19 complaints, although this cannot yet be said with certainty.

    Similar findings have been previously reported also in China.

  • Chinese coronavirus can survive for days on plastic and stainless steel

    Chinese coronavirus can survive for days on plastic and stainless steel

    American research published in “The New England Journal of Medicine“ shows that under ideal conditions, the novel coronavirus (SARS-CoV-2) that emerged in Wuhan and wreaked havoc around the world, remains intact on plastic and stainless steel surfaces for up to 72 hours. In very small droplets in the air, so-called aerosols, it can ‘survive’ for a few hours. Therefore, the widespread hygiene advices are welcome under the current circumstances.

    The researchers at the National Institute of Allergy and Infectious Diseases in Hamilton, MT, performed laboratory measurements on how long the viral particles survive in aerosols as well as on plastic, stainless steel, copper and cardboard surfaces. The meaning of ‘survival’ is that the virus would still be able to multiply in cells.

    According to the Dutch virologist Eric van Gorp of the Erasmus Medical Center in Rotterdam, this research confirms what we actually already knew: that respiratory viruses can spread through direct contact. “Each virus has different properties and therefore behaves differently. Now it has been neatly demonstrated that this corona virus does indeed spread through the air and via surfaces.”

    This is in line with what was already posted on the Public Health Service (RIVM) website: that the coronavirus can ‘survive’ outside the body for several hours to several days, depending on the type of materials and conditions.

    Most cases caused by airborne infections
    The exact lifetime of the virus on shopping carts, door handles and light buttons cannot be determined based on this study. “In this laboratory study, the conditions for the virus were ideal,” says Van Gorp. “In practice, factors such as higher temperature, lower humidity and more wind shorten the ‘life span’ of the virus.”

    According to Mariet Feltkamp, ​​a medical virologist at the Leiden University Medical Center, the main message is that in some circumstances it takes many hours for the amount of virus to decrease significantly. That is why we have to wash our hands.

    Van Gorp emphasizes that the main infection route is still airborne. “I see people who use alcohol all day long for disinfection, which is unnecessary. The most effective measures are keeping a safe distance as well as coughing and sneezing into your elbow. Washing hands fewquently contributes to good hygiene.”

    Whether the Chinese coronavirus survives on surfaces longer than other viruses cannot be determined on the basis of this research. “Unfortunately, this study only compares the current novel coronavirus (SARS-CoV-2) to the virus that caused SARS in 2003 (SARS-CoV-1) and not to other common cold or flu viruses,” said Feltkamp.

    European rover is still two years away from Mars

    The European Mars mission Exomars 2020 should be given a new name, because this year launch has been postponed to 2022. The European space agency ESA made the announceent this week after consultation with mission partner Roscosmos, the Russian space agency.

    ESA executives decided to postpone the mission to run additional tests on the equipment. Also, the coronavirus outbreak plays a role in the decision, as the experts needed for the final stages before launch cannot travel throughout Europe.

Even the popular ones like VigRX in UK come with their shop viagra own set of limitations. Now, it takes two years longer to launch the mission instead of a few months, mainly because of Mars’ orbital position which is best for launches once every two years. At any other times, the red planet is still too far from Earth, therefore a space flight takes longer than necessary.

    All preparations for the mission have now been completed. The Russian lander has all its instruments on board and the European rover, named after the chemist Rosalind Franklin, recently completed the final tests. Parachutes required for landing have been successfully tested by the US space agency NASA.

    Nevertheless, ESA and Roscosmos want to do extra tests, to be completely sure that everything will go well. If the landing succeeds, it will be for the first time when a non-American spacecraft will successfully land on the red planet.

    Elon Musk announced price of Starship launch that will take humans into space

    Starship shuttles could carry up to 100 passengers into the outer space at a cost of “only” two million dollars, cheaper than the price of the current launches.

    Space exploration is a noble objective but also extremely expensive. However, according to SpaceX CEO Elon Musk, the cost of a launch could drop considerably, to as low as just $2 million.

    While there are some medical advancements 100mg tablets of viagra in this field, many men still suffer in silence, embarrassed to talk to a doctor about it.

Elon Musk says that the Starship shuttles, which are expected to convey up to 100 people, will be powered by reusable Super Heavy rockets, and that will greatly reduce the costs of the launch.

    He estimates that the fuel needed for a lift-off will cost around $900,000, with the remaining amount up to $2,000,000 being represented by operational costs.

    This price estimate was made during the Space Pitch Day event, where private companies are trying to sell their services and technologies to the United States Air Force.

  • Global warming affects air traffic over North Atlantic

    Global warming affects air traffic over North Atlantic

    A recent study concluded that the clear air turbulence experienced by aircraft over the Atlantic Ocean is increasing due to climate warming.

    In a new study published in journal Nature, scientists concluded that there is a statistically significant increase in the movement and direction of air masses associated with turbulence experienced by aircraft flying over the North Atlantic.

    This statistical increase in clear sky turbulence has real effects on global aviation traffic, given that about 3,000 airplanes fly over the North Atlantic daily. Due to its busy air traffic and exposure to polar air masses, the scientists have chosen the northern region to be analized in their research.

    These kinds of internet medication providers are numerous and include deep spinal muscles such as rotatores and multifidus, the erector spinae, obliques, seanamic.com cheapest levitra transversus abdominus, quadratus lumborum and the rectus abdominus. Females generally suffer with depression and levitra cialis Check Out Your shop they have to face menopause, so it is very common that women lost interest in sex at 45 years of age. As a result there is an increased flow of blood into the penile region. cialis sale australia That’s the reason you’ll need a quiet resort to return to levitra sale track. The turbulence study focused on the thermal wind which is driven by the temperature gradient between the equator and the North Pole. A more pronounced temperature difference is associated with a faster movement of the air stream from west to east.

    In this study, meteorologists at Reading University concluded that at higher altitudes, reaching lower stratosphere above the North Pole, the temperature decreases as a reaction to climate changes in the Arctic region. Towards the equator, the opposite phenomenon is noticed: temperature increases at higher altitudes. This results in a larger temperature contrast at this altitudes.

    The higher temperature changes in different regions of the stratosphere interact with the lower changes in temperatures in different regions of the lower troposphere and they tend to balance out weakening the jet stream. However, scientists have noticed that the movement of the air streams in these regions is increasing, which results in the turbulence of aircraft flying over the Atlantic.

    The researchers concluded that they expect an amplification of these turbulences in the future, compared to the current situation. They also pointed out that climate projections in the North Atlantic area show that this region will be the most affected by these phenomena.
