Land plants - plants that live primarily in terrestrial habitats and form vegetation on earth - are anchored to the ground through their roots, and their performance depends on both the belowground soil conditions and the aboveground climate. Plants utilize sunlight to grow through the process of photosynthesis where light energy is converted to chemical energy in chloroplasts, the powerhouses of plant cells. Therefore, the amount and quality of light perceived by chloroplasts through light absorbing pigments, such as chlorophyll, is a defining factor in plant growth and health.

An international study has elucidated the structure of a protein that is required for the assembly and stability of photosynthetic membranes.

East Hanover, NJ. July 2, 2021. Among wheelchair users with spinal cord injury 42 percent reported adverse consequences related to needing wheelchair repair, according to a team of experts in spinal cord injury rehabilitation. The research team, comprised of investigators from the Spinal Cord Injury Model System, determined that this ongoing problem requires action such as higher standards of wheelchair performance, access to faster repair service, and enhanced user training on wheelchair maintenance and repair.

This insight is the result of the close collaboration of several research groups at the Max Planck Institute for Marine Microbiology. A team around Cedric Hahn and Gunter Wegener recently discovered ethane-degrading microbes at hydrothermal vents of the Guaymas Basin at a water depth of 2,000 meters in the Gulf of California. They named it Ethanoperedens thermophilum, which means "heat-loving ethane-eater". Cedric Hahn a PhD student from the research group Molecular Ecology cultured the ethane-degrading microbes in the laboratory.

CHAPEL HILL, NC - Scientists at the University of North Carolina at Chapel Hill School of Medicine and colleagues have demonstrated that variants in the SPTBN1 gene can alter neuronal architecture, dramatically affecting their function and leading to a rare, newly defined neurodevelopmental syndrome in children.

Zeolites are extremely porous materials: Ten grams can have an internal surface area the size of a soccer field. Their cavities make them useful in catalyzing chemical reactions and thus saving energy. An international research team has now made new findings regarding the role of water molecules in these processes. One important application is the conversion of biomass into biofuel.

Fuel made from biomass is considered to be climate-neutral, although energy is still needed to produce it: The desired chemical reactions require high levels of temperature and pressure.

30 June 2021: A large cohort study drawn from the national IVF registry of France, which included almost 70,000 pregnancies delivered after 22 weeks gestation between 2013 and 2018, has found a higher risk of pre-eclampsia and hypertension in pregnancies derived from frozen-thawed embryos. This risk was found significantly greater in those treatments in which the uterus was prepared for implantation with hormone replacement therapies. The results confirm with real-life data what has been observed in sub-groups of patients in other studies.

Neuroscientists at UCL have, for the first time, identified abnormalities in the way memories are 'replayed' in the brains of people with schizophrenia; researchers say the pathbreaking study provides an entirely new basis for explaining many of the condition's core symptoms.

Schizophrenia is a serious and debilitating mental disorder characterised by episodes of psychosis. Symptoms include hallucinations (typically hearing voices), delusions, and disorganised thinking. It affects around 20 million people globally, though the exact cause is unknown.

Spatial reasoning ability in small children reflects how well they will perform in mathematics later. Researchers from the University of Basel recently came to this conclusion, making the case for better cultivation of spatial reasoning.

Dinosaurs roamed the Earth more than 65 million years ago, and paleontologists and amateur fossil hunters are still unearthing traces of them today. The minerals in fossilized eggs and shell fragments provide snapshots into these creatures' early lives, as well as their fossilization processes. Now, researchers reporting in ACS Earth and Space Chemistry have analyzed the molecular makeup of fossilized dinosaur eggshells from Mexico, finding nine amino acids and evidence of ancient protein structures.

Tel Aviv University's groundbreaking technology may revolutionize the treatment of cancer and a wide range of diseases and medical conditions. In the framework of this study, the researchers were able to create a new method of transporting RNA-based drugs to a subpopulation of immune cells involved in the inflammation process, and target the disease-inflamed cell without causing damage to other cells.

Pioneering research has revealed the erosion of ancient sediments found deep beneath Antarctic ice could be a vital and previously unknown source of nutrients and energy for abundant microbial life.

The study, led by the University of Bristol and published today in Nature's Communications Earth & Environment journal, sheds new light on the many compounds supporting various microbes which form part of a huge subglacial ecosystem.

Crystallization is one of the most fundamental processes found in nature - and it's what gives minerals, gems, metals, and even proteins their structure.

In the past couple of decades, scientists have tried to uncover how natural crystals self-assemble and grow - and their pioneering work has led to some exciting new technologies - from the quantum dots behind colorful QLED TV displays, to peptoids, a protein-mimic that has inspired dozens of biotech breakthroughs.

During the last twenty years, the trading in stock markets has undergone significant changes. Researchers from the University of Turku and the University of Palermo have investigated the role of high-frequency traders in the markets.

Technological evolution and innovations both in the technology used by stock exchanges and the resources of the traders using their services have made faster trading possible. As a result, high-frequency trading in sub millisecond scale has increased.

HOUSTON - (June 29, 2021) - The story of halichondrin B, an inspirational molecule obtained from a marine creature, goes back to the molecule's discovery in an ocean sponge in 1986.

Though it has been replicated in the laboratory several times before, new work by Rice University chemists could make halichondrin B and its naturally occurring or designed variations easier to synthesize.
