Highlighting the effectiveness of the COVID-19 vaccines could hold key to converting doubters

The study, led by the University of Bristol and published in the British Journal of Health Psychology, shows the importance of raising awareness of vaccine efficacy, especially if it compares very favourably to another well-established vaccine. The research focused on adults who were unsure about being vaccinated against COVID-19. Those who were […]

Memory-making involves extensive DNA breaking

The urgency to remember a dangerous experience requires the brain to make a series of potentially dangerous moves: Neurons and other brain cells snap open their DNA in numerous locations — more than previously realized, according to a new study — to provide quick access to genetic instructions for the mechanisms […]

Breakthrough into leading cause of blindness

A University of Manchester led a team of scientists has discovered that the most common form of adult blindness is probably caused by a failure of at least one of five proteins to regulate the immune system. The breakthrough could one day herald the development of transformative treatments for developing […]

Using “guilt by association” to classify cells

Biologists are trying to figure out what makes a cell unique in form and function. But they are not certain which components are key to making similar cells behave differently. Cold Spring Harbor Laboratory (CSHL) Associate Professor Jesse Gillis and his lab are tackling this problem with a new statistical method: they […]

Preventing lung cancer’s unwelcome return

When a doctor gives a patient antibiotics for a bacterial infection, they usually require them to finish the entire treatment, even when symptoms go away. This is to ensure the drugs kill off any remaining bacteria. Cold Spring Harbor Laboratory (CSHL) Visiting Scientist Raffaella Sordella investigated a similar problem that occurs in […]

COVID-19 vaccine antibodies weaker vs. Delta/Kappa viral variants

Antibodies induced by currently available mRNA vaccines can still neutralize the Delta and Kappa variants of the SARS-CoV-2 virus, but do so at a reduced potency, according to a report published in the New England Journal of Medicine. The Delta variant, first identified in India and previously known as B.1.617.2, is […]

Interdisciplinary team researches potential treatments for intervertebral disc disease

Intervertebral discs provide load support and motion between vertebrae in the spine, but when they start to break down and compress due to ageing, disease or injury, a person experiences significant pain and reduced mobility. An interdisciplinary team of researchers at Washington University in St. Louis found a way to […]

Species of gut bacteria linked to enhanced cognition and language skills in infant boys

Infant boys with a higher composition of a particular gut microbiota show enhanced neurodevelopment, according to a new study. The University of Alberta-led research followed more than 400 infants from the CHILD Cohort Study (CHILD) at its Edmonton site. Boys with a gut bacterial composition that was high in the bacteria Bacteroidetes […]

The long view on COVID-19 vaccine safety and efficacy

The mRNA vaccines for COVID-19, made by Pfizer/BioNTech and Moderna, are among the most powerful vaccines the world has ever seen. According to clinical trial data, they are more than 94% effective at preventing symptomatic disease, with real-world data bearing out that success. The other vaccine currently available in the […]

Species of algae with three sexes that all mate in pairs identified in Japanese river

For 30 years, University of Tokyo Associate Professor Hisayoshi Nozaki has traveled an hour west of Tokyo to visit the Sagami River and collect algal samples to understand how living things evolved different sexes. Through new analysis of samples collected in 2007 and 2013 from dam lakes along the river, […]

Study IDS Risk Factors for Irregular Heartbeats in Hypertrophic Cardiomyopathy Patients

New research will help doctors identify, treat and prevent potentially dangerous irregular heartbeats in patients with hypertrophic cardiomyopathy, a common heart condition in which the heart thickens and strains to pump blood. These chaotic heart rhythms are known as atrial fibrillation. Atrial fibrillation can be asymptomatic, but it can lead […]

Study Finds COVID-19 Reinfection Rate Less Than 1% for Those with Severe Illness

A review of more than 9,000 U.S. patients with severe COVID-19 infection showed less than 1% contracted the illness again, with an average reinfection time of 3.5 months after an initial positive test. Those are the findings from a study conducted by researchers from the University of Missouri School of Medicine and MU […]

Rats prefer to help their own kind. Humans may be similarly wired

A decade after scientists discovered that lab rats will rescue a fellow rat in distress, but not a rat they consider an outsider, new UC Berkeley research pinpoints the brain regions that drive rats to prioritize their nearest and dearest in times of crisis. It also suggests humans may share […]

Your Immune System Could Turn COVID-19 Deadly

Hidden autoimmunity may explain how the coronavirus wreaks such widespread and unpredictable harm. One of the enduring mysteries of COVID-19 is why it makes some people deathly sick but gives others only mild symptoms or none at all. We know that age matters, as do race; gender; and pre-existing medical […]

Gene Therapy Offers Long-Awaited Hope for Children with Rare, Incurable Disorder

Children with a devastating genetic disorder characterized by severe motor disability and developmental delay have experienced sometimes dramatic improvements in a gene therapy trial launched at UC San Francisco Benioff Children’s Hospitals. The trial includes seven children aged 4 to 9 born with a deficiency of AADC, an enzyme involved […]

Identifying the spark of desire in fruit flies

Fruit flies have evolved an elaborate courtship ritual. Upon recognizing a suitable mate in his vicinity, a male fruit fly transforms into a dogged suitor, sometimes chasing the female for more than 26 yards, or 9 miles in human terms, singing to her all the while by vibrating his wings. […]

Anti-androgen therapy may fuel spread of bone tumours in advanced prostate cancer

Anti-androgen therapy is commonly used to treat patients with advanced prostate cancer at stages where the disease has spread to the bones. However, new research reveals that anti-androgen treatment can actually facilitate prostate cancer cells to adapt and grow in the bone tumour microenvironment model, which has been developed by […]

Normal brain growth curves for children developed

In the United States, nearly every pediatric doctor’s visit begins with three measurements: weight, height and head circumference. Compared to average growth charts of children across the country, established in the 1970s, a child’s numbers can confirm typical development or provide a diagnostic baseline to assess deviations from the curve. Yet, […]
