Americans at high risk advised to wear masks as new Covid variant detected

Posted on by

CDC said that scientists discovered a new coronavirus variant, BA 2.86, and that higher-risk individuals should be cautious

As authorities revealed that a new Covid-19 variant has been detected in the US, medical experts are emphasizing that high-risk persons resume masking to prevent potentially deadly infection. Warnings from these physicians come amid an ongoing increase in Covid-19 hospitalizations.

The US Centers for Disease Control and Prevention (CDC) has said that scientists have discovered a new coronavirus variant, BA 2.86, during routine monitoring of wastewater. Officials said that this variant’s “large number of mutations” has prompted concerns that it could evade immunity derived from vaccination and prior infections more than other variants.

Study of chronic fatigue syndrome also finds women are more likely to develop worse symptoms over time

Women with chronic fatigue syndrome (CFS) tend to have more symptoms than men and are more likely to develop increasingly severe symptoms over time, according to initial results from a major study.

It is already known that women are at higher risk of CFS, also known as myalgic encephalomyelitis (ME), and the latest study, called DecodeME, provides new insights into how their experience differs from men. The study found that women who have ME/CFS for more than 10 years are more likely to experience increasingly severe symptoms as they age.

India’s south pole moon landing is big business for global space race

Posted on by

India has raised its spacefaring profile and will now be seen as low-cost provider for missions possible

For all the risks, for all that was riding on a successful landing, the descent to the moon’s surface was remarkably uneventful, if not exactly stress-free. The Vikram lander, part of India’s Chandrayaan-3 mission, dropped steadily on its thrusters to the rock below, slowed to a hover as it approached the ground, and finally came to a rest on the dusty terrain.

When confirmation came that the lander was down, anxiety in the control room gave way to cheers and applause. With the soft touchdown, India becomes the first country to land a probe at the moon’s south pole, a rugged region where deep craters lie in permanent shadow and where ice could provide water, oxygen and fuel for future missions. The first will be on the moon itself, and in lunar orbit, but they could also supply trips to Mars, with the benefit that the materials do not need to be lifted off the Earth’s surface at great cost. It is a region of key scientific interest.

MRI scanning could lead to major cut in prostate cancer deaths, finds UK study

Posted on by

Research found MRI is significantly more accurate than current tests, which are linked to overdiagnosis and overtreatment

Using MRI scans to screen men for prostate cancer could reduce deaths from the disease significantly, researchers have suggested.

Scientists said current tests, which detect the level of the protein prostate-specific antigen (PSA) in the blood, have been linked to overdiagnosis and overtreatment of low-risk cancer.

Research suggests behaviour may reflect evolutionary response to previous outbreaks of disease

Aerial surveys of the North Sea have revealed that seals practise social distancing – and the discovery may have profound implications for the spread of disease among the marine mammals.

In a paper published today by the Royal Society, researchers conducting censuses of grey and harbour seals detail new evidence that the two species not only maintain distances between their own kind (unlike walruses, for instance, who cluster close together) but also that this behaviour may “reflect an evolutionary response to viral susceptibility”.
