Approximately 80 miles from the westernmost reach of China’s Great Wall, paleontologists found relics of an even more ancient world. Over the last two decades, teams of researchers unearthed more than 100 specimens of fossil birds that lived approximately 120 million years ago, during the time of the dinosaurs. However,Continuar Leyendo
T-cell responses directed against the receptor-binding domain of the SARS-CoV-2 spike protein were associated with protection from SARS-CoV-2 infection in vaccinated individuals with or without cancer, with lower T-cell responses observed in patients with blood cancers, according to results from a study published in Cancer Discovery, a journal of theContinuar Leyendo
Zurich, Feb 18, 2022.- Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system and the most common cause of neurological impairment in young adults. In MS, the patient’s own immune system attacks the brain and spinal cord, resulting in cumulative neurological deficits such as damaged sight,Continuar Leyendo
The European Southern Observatory’s Very Large Telescope Interferometer (ESO’s VLTI) has observed a cloud of cosmic dust at the centre of the galaxy Messier 77 that is hiding a supermassive black hole. The findings have confirmed predictions made around 30 years ago and are giving astronomers new insight into “activeContinuar Leyendo
Ten years ago this week, 13 February 2012, ESA opened a new era of independent access to space with the flawless inaugural flight of its small launcher Vega. Flying from Europe’s Spaceport in French Guiana, Vega has gone on to earn a reputation for precision and versatility in anticipation ofContinuar Leyendo
Researchers at the University of Copenhagen have found several hundred different chemical substances in tap water stored in reusable plastic bottles. Several of these substances are potentially harmful to human health. There is a need for better regulation and manufacturing standards for manufacturers, according to the chemists behind the study.Continuar Leyendo
Using atoms only a few billionths of a degree above absolute zero, a team of researchers from ICFO and Aalto University have detected magnetic signals undetectable by any other existing sensor technology. Magnetometers measure the direction, strength or relative changes of magnetic fields, at a specific point in space andContinuar Leyendo
It has long been known that Mars once had oceans due in part to a protective magnetic field similar to Earth’s. However, the magnetic field disappeared, and new research may finally be able to explain why. Researchers recreated conditions expected in the core of Mars billions of years ago andContinuar Leyendo
A number of existing strains of SARS-CoV-2, as well as other future variants that could arise, have the potential to escape the immune system’s cytotoxic T cell response in some portion of the population. That’s the conclusion of a new modeling study publishing Feb. 10 in PLOS Computational Biology byContinuar Leyendo
Vitamin D is most often recognized for its role in bone health, but low levels of the supplement have been associated with a range of autoimmune, cardiovascular, and infectious diseases. Early on in the pandemic health officials began to encourage people to take vitamin D, as it plays a roleContinuar Leyendo
