In the past 5 years, Chicago residents have purchased nearly 1,300 vacant lots and replaced weed trees and sagging fences with gardens and children's play areas. In doing so, they have demonstrated that transferring city-owned vacant lands to local residents can be a successful strategy for cities seeking to reduce blight and strengthen neighborhoods.
A genetic analysis of the American crocodile (Crocodylus acutus) has re-established our understanding of its population structure, aiding its conservation. The collaborative study spanning seven countries and led by the Wildlife Conservation Society and University of Bristol researchers is published in PLOS ONE.
Blood-feeding livestock mites can be detected with wearable sensor technology nicknamed "Fitbits for chickens."
To help farmers detect mite infestations, a team of entomologists, computer scientists, and biologists led by UC Riverside entomologist Amy Murillo has created a new insect detection system. The team's work is detailed in the journal Scientific Reports.
Research has shown that the tumor microenvironment (TME) can help cancers grow and evade the immune response. The TME has even been shown to inhibit cellular immunotherapy, a novel form of treatment in which the cells of a patient's immune system are re-engineered in the lab to attack cancer cells. Therefore, scientists are now developing cellular immunotherapies that attempt not only to promote the anti-cancer activity of the immune system, but also combat the inhibitory effect of the tumor microenvironment.
The Taxaceae are a distinct conifer family widely used in ornamental horticulture and are an important source of chemotherapeutic drugs (e.g., Paclitaxel). Fossil evidence of Taxaceae is based mainly on isolated leaves or leafy shoots for which the reproductive structures are unknown. However, several more complete fossils with attached seed-bearing structures show that Taxaceae had diverged from other conifers by the earliest Jurassic and were probably diverse during the Jurassic and Cretaceous.
New research has identified the specific brain cells that control how much sugar you eat and how much you crave sweet tasting food.
Most people enjoy a sweet treat every now and then. But an unchecked "sweet tooth" can lead to overconsumption of sugary foods and chronic health issues like obesity and type 2 diabetes. Understanding the biological mechanisms that control sugar intake and preference for sweet taste could have important implications for managing and preventing these health problems.
LOS ALAMOS, N.M., July 9, 2020--New research revealed that tiny, sunlight-absorbing particles in wildfire smoke may have less impact on climate than widely hypothesized because reactions as the plume mixes with clean air reduce its absorbing power and climate-warming effect. In a unique megafire study, a Los Alamos National Laboratory-led research team studied the properties of smoke from Arizona's massive Woodbury Fire last summer using a powerful set of observing techniques.
A new study by researchers at the University of British Columbia and the University of Manitoba has found that bacteria are shared and possibly transferred from a mother's milk to her infant's gut, and that breastfeeding directly at the breast best supports this process.
The research, published today in Cell Host & Microbe, found that certain bacteria, including Streptococcus and Veillonella, co-occur in mothers' milk and their infants' stool, and this co-occurrence is higher when infants nurse directly at the breast.
Scientists at USC Dornsife College of Letters, Arts and Sciences may have found the beginnings of a path toward increasing human lifespan.
The research, published July 10 by the Journal of Gerontology: Biological Sciences, shows the drug mifepristone can extend the lives of two very different species used in laboratory studies, suggesting the findings may apply to other species, including human beings.
Countering wear and tear inflicted by males
Solar cells made of perovskite are at the center of much recent solar research. The material is cheap, easy to produce and almost as efficient as silicon, the material traditionally used in solar cells. However, perovskite cells have a love-hate-relationship with the sun. The light that they need to generate electricity, also impairs the quality of the cells, severely limiting their efficiency and stability over time.
Scientists are a step closer to developing a fast and cost effective camera that utilises terahertz radiation, potentially opening the opportunity for them to be used in non-invasive security and medical screening.
Dull. Slow. Unchanging. Like watching paint dry.
But take a closer look at that paint—all the way down to the nanoscale—and there’s a lot more going on than you might think.
BOZEMAN -- A Montana State University professor's research on plant chemistry in the Northern Great Plains and Northern Rockies has been published in Global Change Biology, a prominent journal that promotes exploration of the connections between biological processes and environmental change.
Researchers from the Center for Diagnostics and Telemedicine together with colleagues from Mayo Clinic College of Medicine and Science, University of Munich and Sechenov University used computed tomography to analyze the individual anatomy of the nasolabial triangle. They identified possible options for the distribution of blood vessels on three-dimensional course. It will help in safety planning of plastic and reconstructive surgeries and procedures.
Coupled quantum dots can be an important building block in the development of scalable quantum devices by controlling the quantum states of two adjacent quantum dots (QDs) electrically and optically. Recently, remarkable progress has been made in controlling the coupled states of CQDs, but individual control of vertically stacked quantum dots is still challenging. Unless each dot can provide a logical bit operation, this becomes a limit in progress towards scalable qubit arrays.
