Chemists create a sensor that accurately detects the saliva pH of humans
Chemists at the Ural Federal University have created a sensor for determining the pH of human saliva. This is a fluorophore with strong and stable emission, which picks up the smallest fluctuations in the pH in biological fluids. The analysis is perf.....»»
Private astronauts on daring trek ahead of historic spacewalk
A private crew set out on an audacious orbital expedition Tuesday, journeying deeper into the cosmos than any humans in half a century as they prepare for the first ever spacewalk by non-professional astronauts......»»
Huawei’s $2,800 trifold phone is a real thing it wants people to hold and use
"It’s a piece of work that everyone has thought of but never managed to create." Enlarge / In the U.S., a folding phone has you carrying around nearly $2,000 of fragile, folding OLED phone. In China and export-friendly countrie.....»»
Multiple ways to evolve tiny knee bone could have helped humans walk upright
The evolution of bones in primates' knees could have implications for how humans evolved to walk upright, a new study has found......»»
Thanks to humans, Salish Sea waters are too noisy for resident orcas to hunt successfully
The Salish Sea—the inland coastal waters of Washington and British Columbia—is home to two unique populations of fish-eating orcas, the northern resident and the southern resident orcas. Human activity over much of the 20th century, including red.....»»
Pollution of the potent warming gas methane soars and people are mostly to blame
The amount and proportion of the powerful heat-trapping gas methane that humans spew into the atmosphere is rising, helping to turbocharge climate change, a new study finds......»»
How viruses move through insects for transmission of diseases
Viruses are master parasites that have adapted to infect many host species. Some viruses even use multiple hosts to spread their infections—such as arboviruses that use insects to move their infections to mammalian hosts like humans. Understanding.....»»
Promoting horse welfare with an intestinal disease screening method
Researchers at the University of Jyväskylä, Finland, are developing a promising method to support the diagnosis of inflammatory bowel diseases (IBD) in horses. Awareness of the prevalence of IBD in both humans and animals has increased in recent de.....»»
Study identifies areas of Europe at risk from dengue fever due to spread of Asian tiger mosquito
As Europe grapples with the growing threat of tropical diseases brought by the Asian tiger mosquito, a research breakthrough led by the UK Centre for Ecology & Hydrology (UKCEH) is enabling scientists to accurately predict towns across the continent.....»»
A roadmap for using viruses to enhance crop performance
Humans, livestock and companion animals benefit from virus-based vaccines and gene therapies, but crops do not. This paradox is highlighted by an international research group led by the Institute of Molecular and Cellular Biology of Plants (IBMCP) wi.....»»
First robot leg with "artificial muscles" jumps nimbly: Study
Researchers said on Monday they had designed the first robotic leg with "artificial muscles"—oil-filled bags allowing machines to move more like humans—that can jump nimbly across a range of surfaces......»»
New fusion reactions could lead to long-lasting superheavy nuclei with unique properties
A team of scientists has made significant progress in the ongoing quest to create new, long-lasting superheavy nuclei. These double magic nuclei, characterized by a precise number of protons and neutrons that form a highly stable configuration, are e.....»»
Space travel comes with risk—SpaceX"s Polaris Dawn mission will push the envelope further than ever
Space is an unnatural environment for humans. We can't survive unprotected in a pure vacuum for more than two minutes. Getting to space involves being strapped to a barely contained chemical explosion......»»
How to create a Powerpoint Presentation
Powerpoint presentations are a great way to share information with a team or to make a presentation to a group. Here's how to make one......»»
Making sense of crime scene DNA patterns
Piecing together the evidence to accurately replicate the movements of a culprit at a crime scene is becoming a more exact science, with new investigations by Flinders University and other experts on various DNA transfer scenarios......»»
A cargo bike with a low price and pedals so low they scrape the ground
A budget offering with a torque sensor (good!) and a whole lot of issues (not good). Enlarge / The CycWagon. (credit: John Timmer) More so than most other forms of bicycle, cargo bikes are specifically designed to make d.....»»
Supramolecular material able to store compressed hydrogen in a way that is not too heavy
A team of chemists with members from the University of Hong Kong, Northwestern University and Duke University has developed a supramolecular material that can be used to compress hydrogen for storage that is not too heavy. In their study, published i.....»»
Scientists create guidance to help emergency managers prepare for weather hazards of the future
Climate change is fueling more severe storms and floods, droughts and fires, and communities around the world are grappling with how to prepare. Emergency managers regularly meet to examine possible disasters and discuss preparations and responses fo.....»»
Groundwater use can be accurately monitored with satellites using remote sensing platform, new study finds
Drought is a widespread concern in the Western U.S., and water managers across the region are developing groundwater management plans to conserve the essential resource. Groundwater is often pumped to the surface to irrigate crops, and meters that me.....»»
Space-based experiments could help to advance early cancer detection through blood tests
Imagine a sensor so sensitive it can detect early cancer in a single drop of blood, enabling diagnosis and treatment before the first symptoms—possibly before a tumor even forms......»»
Eclipses create atmospheric gravity waves, student teams confirm
Student teams from three U.S. universities became the first to measure what scientists have long predicted: eclipses can generate ripples in Earth's atmosphere called atmospheric gravity waves. The waves' telltale signature emerged in data captured d.....»»
