Cell adaptation to adverse conditions could differentiate survivors and non-survivors of critical illness

Creating the best conditions for cells to make energy and survive critical illness is a challenge little understood in modern medicine.

Macrophages perform necessary damage-control function following tissue injury

Cardiovascular disease, the most common cause of death, is the result of oxygen deprivation as blood perfusion to affected tissue is prevented. To halt the development of the disease and to promote healing, re-establishment of blood flow is crucial.

Raising water levels in agricultural peatlands could reduce greenhouse gas emissions

Substantial cuts in global greenhouse gas emissions could be achieved by raising water levels in agricultural peatlands, according to a new study in the journal Nature.

Historical CO2 emissions will lead to continuous oxygen depletion in the ocean

The life of almost all animals in the ocean depends on the availability of oxygen, which is dissolved as a gas in seawater. However, the ocean has been continuously losing oxygen for several decades. In the last 50 years, the loss of oxygen accumulates globally to about 2% of the total inventory (regionally sometimes significantly more).

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.

POSTECH researchers bioengineer a novel drug-delivering adhesive patch platform

Blood vessels deliver nutrients and oxygen to each organ in our body. They are difficult to completely restore to their original conditions once damaged by myocardial infarction or severe ischemic diseases. This is because various angiogenic growth factors must be applied sequentially in order to restore the vascular structure.

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.

Novel device can help treat type I diabetes mellitus

Type I Diabetes Mellitus, also called T1D, is an autoimmune disorder that results in an irreversible loss of insulin-producing beta-cells found in the pancreas.

Scientists generate a detailed molecular atlas of lung development

Researchers at the Perelman School of Medicine at the University of Pennsylvania have produced a detailed molecular atlas of lung development, which is expected to be a fundamental reference in future studies of mammalian biology and of new treatments for diseases, such as COVID-19, that affect the lungs.

Study maps structure, mechanism of membrane enzyme that has a role in chronic inflammation, cancer

A majority of the drugs work through the membranes surrounding the cells of the body.

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.

$1 million NSF grant effort to explore a natural process that saps plants' productivity

Plants were evolving for hundreds of millions of years before humans started cultivating them for food. So when the first farmers showed up some 12,000 years ago, plants had already picked up some inefficiencies -- that is, adaptations that helped the plants survive but also limited their productivity as crops.
