Insect decline poses challenges for the pollination of wild and cultivated plants. Landscape ecologists from Münster University have now discovered that the diversity of insects that interact with plant communities is influenced not only by plant species but also by the geographical provenance of seeds. The results of the study have been published in the "Journal of Applied Ecology".

A research team led by Dr. Zhemin Tan, Professor at the School of Atmospheric Sciences of Nanjing University, analyzed the influences of the regional landscape that lead to consistent mesoscale convective systems (MCS) back-building in the Yangtze river basin.

New research by the University of New England's Palaeoscience Research Centre suggests juvenile tyrannosaurs were slenderer and relatively faster for their body size compared to their multi-tonne parents.

Notch proteins are key regulators of growth and differentiation of both normal and cancer cells. Researchers in Turku, Finland, have now demonstrated that the activities of distinct Notch family members are modified differently by phosphorylation. These results can be used in the development of new cancer treatments, especially for hormone-dependent breast cancer.

Tourniquet use has been consistently increasing in Los Angeles County since 2015 and is significantly associated with improved patient survival.

A test which uses artificial intelligence (AI) to measure proteins present in some patients with advanced bowel cancer could hold the key to more targeted treatment, according to research published today.

Scientists have shown that the biological molecule PD-L1 is a potential target for the treatment of metastasized oral malignant melanoma in dogs.

The conversion of light into chemical energy by plants and photosynthetic microorganisms is one of the most important processes in nature, removing climate-damaging CO2 from the atmosphere. Protein complexes, so-called photosystems, play the key role in this process. An international research team shed light for the first time on the structure and function of a transition state in the synthesis of photosystem II.

With an artificial intelligence (AI) method developed by researchers at Aalto University and University of Helsinki, researchers can now link immune cells to their targets and for example uncouple which white blood cells recognize SARS-CoV-2. The developed tool has broad applications in understanding the function of immune system in infections, autoimmune disorders, and cancer.

A research group led by Prof. Hiroyasu Nakano of Department of Biochemistry, Toho University Faculty of Medicine, found that interleukin 11 (IL-11)-positive cells rapidly appear in the colons of mice with colitis and colitis-associated colorectal cancers. In RNA-seq analysis of the gene expression profiles, they found that high expression of enriched genes in IL-11-positive fibroblasts correlated with short duration of disease-free survival in human colorectal cancer patients.

A new molecular 'freeze frame' technique has allowed WEHI researchers to see key steps in how the protein MLKL kills cells.

Rising levels of dementia is putting pressure on residential aged care facilities, including in rural and regional centres where nursing homes and staff are already under pressure. Now a pilot program of personalised interventions, including residents' favourite songs, has been shown to make a big difference to dementia behaviours, drug use and carers' wellbeing.

Living away from community and country, Aboriginal families of children with severe burns also face critical financial stress to cover the associated costs of health care and treatment, a new study shows. An Australian study found feelings of crisis were common in Aboriginal families with children suffering severe burns, with one family reporting skipping meals and others selling assets to reduce costs while in hospital.

Plastics are ubiquitous, but they're not practical. Less than 10% are recycled, and the other ~8 billion tons are creating a pollution crisis. A Berkeley Lab team is determined to change that. A new analysis shows producing and recycling their game-changing new plastic could be easy and cheap enough to leave old plastics in the dust.

Neuroscience researchers at Mayo Clinic Orthopedics and Sports Medicine in Rochester, Minnesota, U.S., the Health and Technology District and Simon Fraser University (SFU) in Surrey, British Columbia, Canada have published the latest results of their ongoing multi-year hockey concussion study examining changes in subconcussive cognitive brain function in male youth ice hockey players. The research showed that repetitive subconcussive impacts triggered compounding effects in brain function changes.

Research by investigators at Harvard Medical School illuminates the neurobiology that underlies food attraction and how hungry mice choose to pay attention to one object in their environment over another.

Stimulus-responsive supramolecular structures have emerged as an alternative to conventional ones, owing to their applications in sensing, drug delivery, and switchable memory systems. Now, scientists at Tokyo Institute of Technology explore the hydrostatic-pressure response of "foldamers"--artificial molecules that mimic protein folding--and report a shift in their preferred conformation with changing pressure, demonstrating hydrostatic pressure-enabled dynamic control. The finding opens doors to future development of pressure-sensitive foldamers and artificial materials.

The primary finding: 87 percent of people who responded to the survey reported that they liked the idea of drone delivery.

Researchers discovered that enriching cell-free vaccine extracts with cellular membranes increased the yields of protein-based vaccines by five-fold, significantly broadening access to potentially lifesaving medicines.
