Unraveling the mystery of viral evolution

All organisms -; from fungi to mammals -; have the capacity to evolve and adapt to their environments. But viruses are master shapeshifters with the ability to mutate greater than any other organism. As a result, they can evade treatments or acquire resistance to once-effective antiviral medications.

Artificial intelligence differentiates cancer cells and detects early viral infections

Researchers at the Centre for Genomic Regulation (CRG), the University of the Basque Country (UPV/EHU), Donostia International Physics Center (DIPC) and the Fundación Biofisica Bizkaia (FBB, located in Biofisika Institute) have developed an artificial intelligence which can differentiate cancer cells from normal cells, as well as detect the very early stages of viral infection inside cells.

With only gloves to protect them, farmworkers say they tend sick cows amid bird flu

In early August, farmworkers gathered under a pavilion at a park here for a picnic to celebrate Farmworker Appreciation Day. One sign that this year was different from the others was the menu: Beef fajitas, tortillas, pico de gallo, chips, beans — but no chicken.

A novel approach to photosynthetic production of high-value compounds

Using evolution as a guiding principle, researchers have successfully engineered bacteria-yeast hybrids to perform photosynthetic carbon assimilation, generate cellular energy and support yeast growth without traditional carbon feedstocks like glucose or glycerol. By engineering photosynthetic cyanobacteria to live symbiotically inside yeast cells, the bacteria-yeast hybrids can produce important hydrocarbons, paving new biotechnical pathways to non-petroleum-based energy, other synthetic biology applications, and the experimental study of evolution.

Stem cell study identifies unique glial contributions to multiple sclerosis

A team of scientists from The New York Stem Cell Foundation (NYSCF) Research Institute and Case Western Reserve University has created the largest reported collection of stem cell models from multiple sclerosis (MS) patients and used them to identify unique ways in which glia – integral support cells in the brain – contribute to the disease.

Funding boost for private clinics fails to improve cataract surgery access for low-income groups

Despite increased funding for cataract surgeries to private, for-profit clinics, access to surgery fell 9% for lower-income people, according to new research published in CMAJ.

MCG researchers investigate spaceflight-induced vision changes in astronauts

Physicians at the Medical College of Georgia at Augusta University are working with Polaris Dawn, the first of the Polaris Program's three human spaceflight missions, to better understand the eye changes many astronauts experience during spaceflight that can leave them with a wide range of symptoms once they return to Earth -; from a new need for glasses to significant loss of vision.

Survey shows Americans support AI in healthcare despite privacy concerns

Artificial intelligence (AI) is all around us – from smart home devices to entertainment and social media algorithms. But is AI okay in healthcare? A new national survey commissioned by The Ohio State University Wexner Medical Center finds most Americans believe it is, with a few reservations.

$3.3 million study to explore eye health in patients with prediabetes and diabetes

A $3.3 million study at the University of Houston College of Optometry will track the health of patients with prediabetes and diabetes to find out who might develop eye problems and be at risk for future vision loss.

New RNA molecules in extracellular vesicles could transform cancer diagnosis

Scientists at the Icahn School of Medicine at Mount Sinai have identified a new class of RNAs packed into tiny particles known as extracellular vesicles (EVs) that could revolutionize how cancer and other diseases are diagnosed.

Study: Early brain wiring driven by spontaneous cellular activity

In humans, the process of learning is driven by different groups of cells in the brain firing together. For instance, when the neurons associated with the process of recognizing a dog begin to fire in a coordinated manner in response to the cells that encode the features of a dog -; four legs, fur, a tail, etc. -; a young child will eventually be able to identify dogs going forward.
