Walking and cycling have many benefits and help reduce greenhouse gas emissions, but researchers say we need to think about what people eat to fuel their walking and cycling.

In a paper published in the international journal, Scientific Reports, the researchers say people who shift from passive modes of transport, such as driving, to active modes, such as walking, will have higher energy needs, which could lead to an increase in food-production related emissions.

Researchers from North Carolina State University have developed a fundamentally new approach to DNA data storage systems, giving users the ability to read or modify data files without destroying them and making the systems easier to scale up for practical use.

Scientists at St. Jude Children's Research Hospital, UCSF Benioff Children's Hospitals and Baylor College of Medicine are investigating how to best treat hemophagocytic lymphohistiocytosis (HLH), a rare immune disorder. Their work, appearing as an advance online publication today in Blood, details how combining two drugs may be a good treatment for HLH.

When drought reshuffles the green-up of habitats that mule deer migrate across, it dramatically shortens the annual foraging bonanza they rely on.

That is the main finding of a new University of Wyoming study, which shows the benefits of migration are likely to decrease for mule deer and other migratory herbivores as drought becomes more common due to ongoing climate change.

Drought reduces the availability of key food resources by shortening the duration of spring green-up -- and altering the progression of the "green wave" across the landscape.

Researchers at Carnegie Mellon University have developed a method for self-assembling nanostructures with gamma-modified peptide nucleic acid (γPNA), a synthetic mimic of DNA. The process has the potential to impact nanomanufacturing as well as future biomedical technologies like targeted diagnostics and drug delivery.

Advances in transportation technology -- e-scooters and bike share, Lyft & Uber, and autonomous vehicles -- are beginning to have profound impacts on cities. New mobility is changing not only how we travel, but also urban form and development itself. In the near future, we can expect differences in what public transit looks like, the layout of cities, and the places we spend our time. In turn, these changes will likely have additional effects on land use, street design, parking, housing, equity, and municipal finance. Will cities be ready to meet these changes?

Microelectronics utilise various functional materials whose properties make them suitable for specific applications. For example, transistors and data storage devices are made of silicon, and most photovoltaic cells used for generating electricity from sunlight are also currently made of this semiconductor material. In contrast, compound semiconductors such as gallium nitride are used to generate light in optoelectronic elements such as light-emitting diodes (LEDs). The manufacturing processes also different for the various classes of materials.

Scientists have shed new light on how the network of gatekeepers that controls the traffic in and out of plant cells works, which researchers believe is key to develop food crops with bigger yields and greater ability to cope with extreme environments.

Everything that a plant needs to grow first needs to pass through its cells' membranes, which are guarded by a sieve of microscopic pores called aquaporins.

p>ST. LOUIS, MO, June 11, 2020 – Small RNAs are key regulators involved in plant growth and development. Two groups of small RNAs are abundant during development of pollen in the anthers – a critical process for reproductive success. A research collaboration has demonstrated the function of a genetic pathway for anther development, with this pathway proven in 2019 work to be present widely in the flowering plants that evolved over 200 million years ago.

New York, NY--June 11, 2020--Accelerating progress in neuroscience is helping us understand the big picture--how animals behave and which brain areas are involved in bringing about these behaviors--and also the small picture--how molecules, neurons, and synapses interact. But there is a huge gap of knowledge between these two scales, from the whole brain down to the neuron.

Consumers who use the Internet to learn about products are increasingly looking at online reviews to make purchasing decisions. The growing interest in online product reviews for legitimate promotion has been accompanied by a rise in fraudulent reviews; these are reviews placed by firms that artificially inflate ratings of their own products, or reviews by firms or third parties that give lower ratings to competitors' products.

Geriatrics is the field of health care focused on care for older adults. Experts suggest that our current geriatrics workforce needs better preparation to care for the 5.7 million people living with dementia in this country. To help meet this challenge, the Institute of Medicine has called for enhancing educational and training programs for improving the competence of the workforce, and to ensure that our workforce reaches the level needed to serve the growing population of older adults with dementia.

Territorial behaviors in animals, such as a puma using its scent to mark its domain, may help to decrease the severity of a potential disease outbreak--but not without the cost of increased persistence of the disease within the population.

This finding comes from a new study, led by Lauren White, of the University of Maryland's National Socio-Environmental Synthesis Center, published in PLOS Computational Biology.

Researchers from the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB), the Université de Toulouse and the Helmholtz Centre for Environmental Research (UFZ) show how the microbial colonisation of the organism influences the interactions between living organisms, the environment and pathogens, using amphibians like frogs as examples. This is basic research for health prophylaxis.
