New research on avian response to wildfires
Fri, 22 Jun 2018 19:08:58 EDT
New research explores the effects fire has on ecosystems and the wildlife species that inhabit them. Scientists examined the impacts of fires of different severity levels on birds and how that changes as the time since fire increases. Scientists looked across 10 fires after they burned through forests in the Sierra Nevada. A key finding was that wildfire had strong, but varied, effects on the density of many of the bird species that were studied.
Repellent research: Navy developing ship coatings to reduce fuel, energy costs
Fri, 22 Jun 2018 17:48:12 EDT
It can repel water, oil, alcohol and even peanut butter. And it might save the US Navy millions of dollars in ship fuel costs, reduce the amount of energy that vessels consume and improve operational efficiency.
Tiny jumping roundworm undergoes unusual sexual development
Fri, 22 Jun 2018 17:48:10 EDT
Biologists have shown that gonad development varies in other nematodes relative to C. elegans. Specifically, they focused on Steinernema carpocapsae, a nematode used in insect biocontrol applications in lawns and gardens.
The photoelectric effect in stereo
Fri, 22 Jun 2018 17:48:05 EDT
In the photoelectric effect, a photon ejects an electron from a material. Researchers have now used attosecond laser pulses to measure the time evolution of this effect in molecules. From their results they can deduce the exact location of a photoionization event.
Challenging our understanding of how platelets are made
Fri, 22 Jun 2018 17:48:02 EDT
Correlative light-electron microscopy is being used to increase our knowledge of how platelets are made in the body and the results are challenging previously held understandings.
Uncovering lost images from the 19th century
Fri, 22 Jun 2018 17:47:59 EDT
Art curators will be able to recover images on daguerreotypes, the earliest form of photography that used silver plates, after a team of scientists learned how to use light to see through degradation that has occurred over time.
Dynamic modeling helps predict the behaviors of gut microbes
Fri, 22 Jun 2018 17:47:54 EDT
A new study provides a platform for predicting how microbial gut communities work and represents a first step toward understanding how to manipulate the properties of the gut ecosystem. This could allow scientists to, for example, design a probiotic that persists in the gut or tailor a diet to positively influence human health.
'Stealth' material hides hot objects from infrared eyes
Fri, 22 Jun 2018 17:47:52 EDT
Infrared cameras are the heat-sensing eyes that help drones find their targets even in the dead of night or through heavy fog. Hiding from such detectors could become much easier, thanks to a new cloaking material that renders objects -- and people -- practically invisible.
Estimate of 8.5 billion barrels of oil in Texas' Eagle Ford Group
Fri, 22 Jun 2018 17:47:33 EDT
The Eagle Ford Group of Texas contains estimated means of 8.5 billion barrels of oil, 66 trillion cubic feet of natural gas, and 1.9 billion barrels of natural gas liquids, according to a new assessment.
New therapeutic target for slowing the spread of flu virus
Fri, 22 Jun 2018 17:47:31 EDT
Influenza A (flu A) hijacks host proteins for viral RNA splicing and blocking these interactions caused replication of the virus to slow, which could point to novel strategies for antiviral therapies.
Low-cost plastic sensors could monitor a range of health conditions
Fri, 22 Jun 2018 17:47:19 EDT
An international team of researchers have developed a low-cost sensor made from semiconducting plastic that can be used to diagnose or monitor a wide range of health conditions, such as surgical complications or neurodegenerative diseases.
Scientists discover how antiviral gene works
Fri, 22 Jun 2018 17:45:13 EDT
It's been known for years that humans and other mammals possess an antiviral gene called RSAD2 that prevents a remarkable range of viruses from multiplying. Now, researchers have discovered the secret to the gene's success: The enzyme it codes for generates a compound that stops viruses from replicating. The newly discovered compound offers a novel approach for attacking many disease-causing viruses.
Biorenewable, biodegradable plastic alternative synthesized
Fri, 22 Jun 2018 17:45:03 EDT
Polymer chemists have taken another step toward a future of high-performance, biorenewable, biodegradable plastics. The team describes chemical synthesis of a polymer called bacterial poly(3-hydroxybutyrate) ­- or P3HB. The compound shows early promise as a substitute for petroleum plastics in major industrial uses.
Broken shuttle may interfere with learning in major brain disorders
Fri, 22 Jun 2018 10:47:40 EDT
A broken shuttle protein may hinder learning in people with intellectual disability, schizophrenia, or autism.
What causes the sound of a dripping tap -- and how do you stop it?
Fri, 22 Jun 2018 10:47:36 EDT
Scientists have solved the riddle behind one of the most recognizable, and annoying, household sounds: the dripping tap. And crucially, they have also identified a simple solution to stop it, which most of us already have in our kitchens.
