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.

New model simplifies the understanding of vascular malformations

Our bodies are made up of 60,000 miles of complex pipes that play a vital role in transporting nutrients throughout our bodies, performing waste disposal, and supplying our organs with fresh oxygen and blood.

Deep-learning approach to achieve faster and high-resolution photoacoustic computed tomography

It takes a few moments for the sound of thunder to reach our ears after a flash of lightning. This phenomenon is due to the photoacoustic (PA) effect where materials near the lightning instantly expand as the optical energy of the lightning is absorbed and converted into thermal energy.

Removing antibiotics from wastewater with biochar

Farmers must cultivate a large number of crops to feed the world’s expanding population. Water is necessary for crops to grow and thrive, and 70% of the freshwater consumed globally is utilized to irrigate crops.

Realistic model explores new treatments for brain tumors

Until now, the use of models to study the barrier that differentiates the circulatory and nervous systems has been either limited or extremely complex. ETH Zurich researchers have created a more accurate model that can also be used to effectively investigate new treatments for brain tumors.

Revealing a novel form of ferroptosis that may be implicated in diseases caused by acute injury

This study is led by Dr. Anjian Xu (Beijing Clinical Research Institute, Beijing Friendship Hospital, Capital Medical University), Dr. Min Cong (Liver Research Center, Beijing Friendship Hospital, Capital Medical University) and Dr. Junying Ding (Beijing Key Laboratory of Basic Research with Traditional Chinese Medicine on Infectious Diseases, Beijing Hospital of Traditional Chinese Medicine, Capital Medical University).

Beef, pork, chicken, and other meats contain new antioxidants, analysis reveals

Imidazole dipeptides (IDPs), which are abundant in meat and fish, are substances produced in the bodies of various animals, including humans, and have been reported to be effective in relieving fatigue and preventing dementia.

Adding antioxidants to cell cultures for efficient production of antibodies

Researchers at the Department of Chemical Engineering, Indian Institute of Technology, India, have investigated the effects of oxidative stress on the production of monoclonal antibodies (mAbs), and how antioxidants can alleviate this stress to improve their performance.

PFAS chemical helps suppress the neutrophil respiratory burst, study finds

In a new study, researchers found that the PFAS chemical GenX suppresses the neutrophil respiratory burst – the method white blood cells known as neutrophils use to kill invading pathogens.

How the immune response in the brain aggravates epilepsy

Biologists at the University of Iowa have conclusively connected epilepsy with the brain’s immune system.

Researchers discover target enzyme for blast disease

A fungus that plagues rice crops worldwide gains entry to plant cells in a way that leaves it vulnerable to simple chemical blockers, a discovery that could lead to new fungicides to reduce the substantial annual losses of rice and other valuable cereals.
