Scientists detect delayed and reduced antibody responses after BioNTech/Pfizer COVID-19 vaccination in older adults

Vaccination efforts have commenced in most countries, prioritizing older adults and those with comorbidities. They are at a higher risk of severe coronavirus disease (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pathogen. Researchers at the U.S. Centers for Disease Control and Prevention (CDC) detected delayed and reduced antibody and T cell …

Scientists can predict which women will have serious pregnancy complications

Scientists can predict which women will have serious pregnancy complications

Credit: CC0 Public Domain Women who will develop potentially life-threatening disorders during pregnancy can be identified early when hormone levels in the placenta are tested, a new study has shown. Pregnancy disorders affect around one in ten pregnant women. Nearly all of the organ systems of the mother’s body need to alter their function during …

Scientists examine multisensory facilitation near the body in all directions

Scientists examine multisensory facilitation near the body in all directions

A virtual sound source approached or receded in front, rear, left, or right body relative direction. The participants were asked to quickly and accurately detect the tactile sensation of a vibrator attached to their chest, regardless of the sound. When the sound source was approaching in any directions and was closer to the body, the …

Scientists experimentally boost red blood cells to aid sickle cell and other hemoglobin diseases

Credit: National Institutes of Health A series of laboratory studies is underway in the United States to improve gene therapy worldwide for sickle cell disease, a complex and sometimes deadly heritable blood disorder that dramatically affects the structure and function of oxygen-ferrying red blood cells. Sickle cell disease is a devastating disorder that largely affects …

Why scientists are concerned about leaks at biolabs

This general view shows the Wuhan Institute of Virology in Wuhan, in China’s central Hubei province. The theory that COVID-19 might be the result of scientific experiments has thrown a spotlight on the work of the world’s most secure biolabs. While the evidence linking SARS-CoV-2 to the Wuhan Institute of Virology in China is strictly …

Scientists urge end to 14-day rule on lab-grown human embryos 

Scientists urge end to 14-day rule on lab-grown human embryos 

Teams from the University of Cambridge and the Netherlands-based Hubrecht Institute last year reported they had developed a human embryo “blueprint” using human stem cells. Scientists called Wednesday for a key 14-day time limit for growing human embryos in the lab to be relaxed as they outlined new ethical guidelines for the fast-changing world of …
