Scientists developing COVID-19 test that knows you’re sick before you do

Imagine a test that could tell you if you were infected with COVID-19 before you had a single symptom, came at an affordable price without the need to go to a doctor, and returned results in minutes. Those who tested positive could swiftly quarantine themselves, while those who tested negative could head to work or spend time with family without […]

Scientists modify CAR-T cells to target multiple sites on leukemia cells

In a new pre-clinical study published this week in the journal Leukemia, the research team of Children’s Hospital Los Angeles investigator Hisham Abdel-Azim, MD, MS, worked with colleagues to engineer T-cells to identify and target multiple sites on acute lymphoblastic leukemia cells instead of just one. The early collaboration points the way to future clinical trials to test the therapy. […]

Scientists eager to explain brain rhythm boost’s broad impact in Alzheimer’s models

The sweeping extent to which increasing 40Hz “gamma” rhythm power in the brain can affect the pathology and symptoms of Alzheimer’s disease in mouse models has been surprising, even to the MIT neuroscientists who’ve pioneered the idea. So surprising, in fact, they can’t yet explain why it happens. In three papers, including two this year in Cell and Neuron, they’ve […]

Scientists reliably predict people’s age by measuring proteins in blood

The carnival worker who tries to guess your age relies on aspects of your appearance, such as your posture and whether any wrinkles emanate from the corners of your eyes and lips. If the carny’s guess is more than a few years off, you win a stuffed koala. But a team of Stanford University School of Medicine scientists doesn’t need […]

Scientists slam Chinese CRISPR babies research after manuscript released

The gene editing performed on Chinese twins last year meant to immunize them against HIV may have failed in its purpose and created unintended mutations, scientists said Tuesday after the original research was made public for the first time. Excerpts from the manuscript were released by the MIT Technology Review for the purpose of showing how Chinese biophysicist He Jiankui […]

Scientists crack rabies virus weaponry

Researchers have found a way to stop the rabies virus shutting down the body’s immune defence against it. In doing so they have solved a key scientific puzzle and have laid the foundation for the development of new anti-rabies vaccines. Rabies kills an estimated 60,000 people a year, most of them in developing countries, overwhelmingly through dog bites. Monash University […]

Scientists discover a new strain of HIV for the first time since 2000

Scientists find new strain of HIV for the first time since 2000 – and they say the discovery is a step toward ending the pandemic by including it in testing, treatment and potential vaccines Scientists at Abbott Labs have confirmed that a strain of HIV that infected three people in the Democratic Republic of Congo is a new variety of […]

Scientists reverse fibrosis in preclinical studies

In cell and mouse models, Mayo Clinic researchers and collaborators have identified a way to slow and reverse the process of uncontrolled internal scarring, called fibrosis. This disease process has few effective therapies, no cure and can be fatal when it occurs in organs such as the liver (cirrhosis) or lungs (pulmonary fibrosis). The findings appear Wednesday, Oct. 30, in […]
