Using Cellular Reprogramming to Make the Heart Function Like New Again

A recent study using mice has revealed a way to turn back the clock after heart attack. The researchers behind the work used RNAs to instruct cells in an injured heart to eliminate scar tissue and recreate cardiac muscle, allowing the heart to function like new again.

Microalgae Grown in the Lab for Producing Biofuel

A group of researchers at the State University of Campinas (UNICAMP) in Brazil have grown microalgae under controlled conditions in a laboratory in order to use their metabolites, especially lipids, with the prime purpose of producing biofuel.

Sickle Cell Disease Cure? Prime Editing Offers Hope for Blood Disorder

At St Jude Children’s Research Hospital and the Broad Institute of MIT and Harvard, researchers have shown how prime editing could help correct the mutation that results in sickle cell disease in a possibly curative method.

UCF Scientists Develop a Digital Topographical Map of the Cardiac Sympathetic Neural Network

A team of UCF College of Medicine researchers has created a digital topographical map of the cardiac sympathetic neural network, the region that controls the body's heart rate and its "fight-or-flight" response.

Lab-Grown Fat Could Give a More Realistic Texture and Flavor to Cultured Meat Grown from Cells

Researchers at Tufts University have successfully bulk-produced fat tissue in the lab that has a similar texture and make-up to fat tissue naturally occurring in animals.

DELLA Proteins: The Road to the Next Green Revolution

Despite being largely unchanged for over 450 million years, a family of “promiscuous” proteins that are present in all land plants is responsible for a wide range of plant activities.

First atomic-level structure of 'oil-eating' enzyme paves way for bioengineered catalysts

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have produced the first atomic-level structure of an enzyme that selectively cuts carbon-hydrogen bonds-;the first and most challenging step in turning simple hydrocarbons into more useful chemicals.

Key gene involved in crop alkaline tolerance discovered

Chinese scientists have identified a key gene involved in crop alkaline tolerance that may greatly improve crop yield in sodic environments through the use of genetic engineering.

Novel low oxygen signaling pathway discovered in the Arabidopsis plant

Aerobic reactions are essential to sustain plant growth and development. Impaired oxygen availability due to excessive water availability, e.g., during waterlogging or flooding, reduces plant productivity and survival.

Olive oil by-products could have antioxidant benefits

New research has found that a natural by-product of olive oil production could potentially have antioxidant benefits and support exercise.

Scientists reveal mechanisms behind oxygen toxicity

When it comes to oxygen, you can have too much of a good thing. Breathing air that contains higher levels of oxygen than the usual 21 percent found in Earth's atmosphere can cause organ damage, seizures, and even death in people and animals, particularly if it's in excess of the body's oxygen needs. Until now, however, scientists have mostly speculated about the mechanisms behind this phenomenon, known as oxygen toxicity, or hyperoxia.

Understanding gas transfer between the atmosphere and ocean can lead to better climate models

The injection of bubbles from waves breaking in turbulent and cold high-latitude regions of the high seas is an underappreciated way in which atmospheric gases are transported into the interior ocean.

Study pinpoints a splicing deregulation that causes therapeutic vulnerability in pediatric AML

Pediatric acute myeloid leukemia or pAML is a childhood blood cancer, one that has proved confounding to clinicians and researchers, with a high relapse rate and relatively few identified genetic mutations (compared to the adult version) that might explain its cause.

Analyzing microscopic chalk disks coccoliths formed by the marine algae

Under the guidance of Rutgers University, a research group learning about virus-host interactions of worldwide abundant and armor-plated marine algae, Emiliania huxleyi, has discovered that the circular and chalk plates produced by the algae have the potential to serve as catalysts for viral infection.

Researchers provide an entirely new perspective on tissue oxygenation

Cardiovascular medicine, hematology and pulmonary medicine may soon have the first-ever therapies to correct poor tissue oxygenation, a key driver of disease in millions, including peripheral artery disease, sickle cell disease, heart failure, stroke, emphysema and many others.

Disinfecting water with peptide-coated silver sulfide quantum dots

Water contaminated with bacteria poses a serious threat to global health. In the scientific publication Angewandte Chemie, a Chinese research team developed a simple new technique for disinfection.

Experts reveal the link between necrosis, circulating tumor cells, and cancer metastasis

A tumor's necrotic core contains factors that appear to promote metastasis, or the seeding of tumors cells throughout the body, according to a new study in rats by researchers at Fred Hutchinson Cancer Center.

Study reveals why the FMO5 gene produces an enzyme with a different activity

Our body produces lots of enzymes that break down toxic substances. One class of such enzymes are the flavin-containing monooxygenases (FMOs), which are present in all tetrapods. Humans have five different FMO genes, of which the first four display the same activity. However, the fifth FMO gene triggers a different breakdown reaction. University of Groningen biochemists have succeeded in resurrecting the ancestral genes of all tetrapod FMOs to show how this divergence has occurred. Their results appear on 24 February in Nature Communications.
