Study highlights the importance of autophagy in gene regulation

A fine balance between the production and degradation of biomolecules is required for optimal cell function. Autophagy is a mechanism through which cells break down and recycle their own components.

Researchers use information embedded in microbial genes as a biosensor of ocean health, productivity

Scientists from the University of California, Irvine, analyzed gains and losses in the genes of phytoplankton samples gathered from all major ocean regions to develop the most refined and highest-resolution map that shows where these photosynthetic organisms either survive or are forced to adapt to restricted amounts of main nutrients, nitrogen, iron, and phosphorus.

Gene therapy protects eye cells in mice with retinitis pigmentosa

A gene therapy protects eye cells in mice with a rare disorder that causes vision loss, especially when used in combination with other gene therapies, shows a study published today in eLife.

Study reveals DNA supercoiling is involved in regulating gene expression

The (when stretched) two-meter-long DNA molecule in each human cell is continuously being unpacked and packed again to enable the expression of genetic information.

Researchers identify and test drug combination that exploits a weakness in small cell lung cancer

Researchers from the National Institutes of Health have identified and tested a drug combination that exploits a weakness in small cell lung cancer (SCLC), an aggressive, dangerous cancer.

Warped immune cell signaling during bile acid exposure may lead to Crohn’s disease

People with Crohn's disease are typically treated with powerful anti-inflammatory medications that act throughout their body, not just in their digestive tract, creating the potential for unintended, and often serious, side effects.

High ozone concentrations decrease crop yield in maize

Although stratospheric ozone protects us by filtering out the sun's ultraviolet radiation, tropospheric ozone is a harmful pollutant. A new study has shown that ozone in the lower layers of the atmosphere decreases crop yields in maize and changes the types of chemicals that are found inside the leaves.

Researchers use single-cell RNA sequencing to study the development of leaves

How do we become a complex, integrated multicellular organism from a single cell? While developmental biologists have long researched this fundamental question, Stanford University biologist and HHMI investigator Dominique Bergmann's recent work on the plant Arabidopsis thaliana has uncovered surprising answers.

Targeting epigenetic mechanisms to advance pharmacological treatments for alcoholism

Abusive alcohol drinking considerably impacts human health. Alcoholism, better defined as Alcohol Use Disorders (AUD), includes a group of pathological entities related to alcohol-induced damage.

Plants use signaling molecule to regulate their water balance

During drought conditions, plants utilize a signaling molecule known from animals to reduce their water loss.

Key molecule determines the pathogenesis of lupus

A new research work, published in JCI, has discovered that the endoplasmic reticulum of a neutrophil becomes stressed in the autoimmune disorder lupus.

Specific genes play key roles in response to water stress across bioenergy grass species

The Miscanthus genus of grasses, commonly used to add movement and texture to gardens, could quickly become the first choice for biofuel production. A new study shows these grasses can be grown in lower agricultural grade conditions - such as marginal land - due to their remarkable resilience and photosynthetic capacity at low temperatures.

Study of leaf size in grasses can help accurately model the effects of climate change

One-third of the Earth's surface is covered by more than 11,000 grass species -- including crops like wheat, corn, rice and sugar cane that account for the bulk of the world's agricultural food production and important biofuels. But grass is so common that few people realize how diverse and important it really is.

Stem cell therapy could help restore debilitating muscle loss that happens with age

As the name implies, induced pluripotent stem cells can become any type of cell in our body, and scientists have evidence that when they prompt them to become muscle progenitor cells they can help restore the sometimes debilitating muscle loss that happens with age.

New technique based on AI can automate and streamline seed quality analysis

In Brazil, researchers affiliated with the Center for Nuclear Energy in Agriculture (CENA) and the Luiz de Queiroz College of Agriculture (ESALQ), both part of the University of São Paulo (USP), have developed a methodology based on artificial intelligence to automate and streamline seed quality analysis, a process required by law and currently done manually by analysts accredited with the Ministry of Agriculture.

Marine heatwaves strongly impact the functioning of coraligen in the Mediterranean

Marine heatwaves are dramatically affecting the marine ecosystems of the world and the Mediterranean is no exception. In the Mediterranean, these extreme climate episodes and its resulting massive mortality of species are getting more and more intense and frequent.
