Oxford University scientists have assessed the decrease in the effectiveness of Pfizer/BioNTech and AstraZeneka vaccines over time. In Israel, mandatory revaccination is carried out for everyone over the age of 50. Scientists from the San Raffaele Scientific Institute have found that colds reduce the effectiveness of the Pfizer/BioNTech vaccine. The head of the Gamalea Center, Alexander Ginzburg, believes that if the current rates of vaccination are maintained, collective immunity will be achieved in Russia in 2021.
Some people regularly go for a run, manage to go to the gym after work and easily wake up at five in the morning. Others do not always find the strength to get up from the couch and turn on the next episode of their favorite series. Is a person to blame for his laziness? Or was it passed on to him from mom and dad along with freckles and receding hairline?
A recent study suggests that the development and evolution of humans is happening faster than at any time in the last 250 years. These conclusions were reached by scientists from Flinders University and the University of Adelaide, who found that since the end of the XIX century, people increasingly have an artery in the forearm, which usually disappears about eight weeks after birth.
Scientists have been struggling for years to unravel the secret of why a person is initially born right—handed or left-handed - and why their ratio is so unequal.
Radio waves, light from a light bulb in the ceiling, invisible rays in the radiologist's office and mysterious deadly radiation in exclusion zones are all just different manifestations of the same physical phenomenon: electromagnetic radiation. It's not so difficult to figure out where everything is. It is enough only to associate the properties of radiation with the wavelength.
The locals considered the animal a manifestation of divine intervention and worship the mutant.
In 2018, a young man in Pakistan went to the hospital with an unusual problem: a second, tiny nail grew on his finger, causing painful discomfort.
In the DNA of the inhabitants of Iceland, a mutation of the ASGR1 gene was found, the presence of which reduces the risk of heart disease by more than 34%. A team of DeCODE researchers compared the genomes of thousands of Icelanders and compared the results of the analysis with information from medical records.
To answer this question, scientists compared the genome of giraffes and their closest relatives, okapi, with the genomes of more than 40 species of other mammals, including cows, sheep, camels and humans.
One of the most terrible diseases that nature bestows on a person is genetic diseases. It is possible to successfully fight the pathogens of ailments - bacteria and viruses, but if the problem is in the human genome from birth, it is extremely difficult to help the patient. Modern science is stubbornly looking for an opportunity to repair mutated genes.
