Why scientists still don t know how long humans can live Salon 5/2/2021 Senior couple on beach Roger Wright/Getty Images
Humans are living longer.
In the late 1890s, the average lifespan was 41 years. In the 1920s, more people lived into their 50s and 60s. In 2021, the average U.S. life expectancy is now a staggering 78.9 years but it s not uncommon for someone to live well into their 90s, even to 100, an age that seemed impossible a century ago. Indeed, as time goes on and humans continue to live longer, scientists are wondering: is there a threshold on how long a human can live or will life expectancy for humans continue to gradually increase over time?

NEW YORK, NY (April 29, 2021) - In a new resource for the scientific community, published today in
Nature Biotechnology, researchers in the lab of Neville Sanjana, PhD, at the New York Genome Center (NYGC) and New York University (NYU) developed CRISPR-sciATAC, a novel integrative genetic screening platform that jointly captures CRISPR gene perturbations and single-cell chromatin accessibility genome-wide. With this technology, they profile changes in genome organization and create a large-scale atlas of how loss of individual chromatin-altering enzymes impacts the human genome. The new method harnesses the programmability of the gene editing system CRISP

Scientists in China are developing a blood test that can quickly determine if a person with chest pain is having a heart attack. They believe the test could replace invasive and slower procedures and limit the damage for heart attack patients.
Researchers at the Albert Einstein College of Medicine in New York have designed a drug that reverses key symptoms of Alzheimer’s disease in mice. Doctors say some factors that contribute to Alzheimer’s in mice also occur in humans which gives hope this drug may one day help people with the disease.
