New research on avian response to wildfires



Posted: 22 Jun 2018 04:08 PM PDT


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



Posted: 22 Jun 2018 02:48 PM PDT


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



Posted: 22 Jun 2018 02:48 PM PDT


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



Posted: 22 Jun 2018 02:48 PM PDT


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



Posted: 22 Jun 2018 02:48 PM PDT


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



Posted: 22 Jun 2018 02:47 PM PDT


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



Posted: 22 Jun 2018 02:47 PM PDT


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



Posted: 22 Jun 2018 02:47 PM PDT


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



Posted: 22 Jun 2018 02:47 PM PDT


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



Posted: 22 Jun 2018 02:47 PM PDT


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



Posted: 22 Jun 2018 02:47 PM PDT


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



Posted: 22 Jun 2018 02:45 PM PDT


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



Posted: 22 Jun 2018 02:45 PM PDT


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



Posted: 22 Jun 2018 07:47 AM PDT


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?



Posted: 22 Jun 2018 07:47 AM PDT


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.


Drug compound stops cancer cells from spreading in mice



Posted: 22 Jun 2018 07:47 AM PDT


New research shows that it may be possible to freeze cancer cells and kill them where they stand.


Miniature testing of drug pairs on tumor biopsies



Posted: 22 Jun 2018 07:47 AM PDT


Combinations of cancer drugs can be quickly and cheaply tested on tumour cells using a novel device developed by scientists. The research marks the latest advancement in the field of personalized medicine.


Mosquito-borne diseases in Europe: Containment strategy depends on when the alarm sets off



Posted: 22 Jun 2018 07:47 AM PDT


New research based on the Italian experience with outbreaks of Chikungunya, a disease borne by the tiger mosquito, in 2007 and 2017, shows that different vector control strategies are needed, depending on the time when the first cases are notified, 'thus providing useful indications supporting urgent decision-making of public health authorities in response to emerging mosquito-borne epidemics', one of the researchers says.


Important step towards a computer model that predicts the outcome of eye diseases



Posted: 22 Jun 2018 07:47 AM PDT


Understanding how the retina transforms images into signals that the brain can interpret would not only result in insights into brain computations, but could also be useful for medicine. As machine learning and artificial intelligence develop, eye diseases will soon be described in terms of the perturbations of computations performed by the retina. A newly developed model of the retina can predict with high precision the outcome of a defined perturbation.


People with schizophrenia account for more than one in 10 suicide cases



Posted: 22 Jun 2018 07:47 AM PDT


A new study shows that people with schizophrenia account for more than one in 10 cases of suicide in Ontario, and that young people are disproportionately affected. People with schizophrenia also had more contact with the health care system, pointing to an opportunity to intervene. The researchers emphasize the need for early suicide risk assessments to reduce risks.


Starving fungi could save millions of lives each year



Posted: 22 Jun 2018 07:46 AM PDT


Researchers have identified a potentially new approach to treating lethal fungal infections that claim more than 1.6 million lives each year: starving the fungi of key nutrients, preventing their growth and spread.


Wolf reintroduction: Yellowstone's 'landscape of fear' not so scary after all



Posted: 22 Jun 2018 07:45 AM PDT


After wolves were reintroduced to Yellowstone National Park in the mid-1990s, some scientists thought the large predator reestablished a 'landscape of fear' that caused elk, the wolf's main prey, to avoid risky places where wolves killed them. But according to recent findings, Yellowstone's 'landscape of fear' is not as scary as first thought.


Normalization of 'plus-size' risks hidden danger of obesity



Posted: 22 Jun 2018 07:45 AM PDT


New research warns that the normalization of 'plus-size' body shapes may be leading to an increasing number of people underestimating their weight - undermining efforts to tackle England's ever-growing obesity problem. Analysis of data from almost 23,460 people who are overweight or obese revealed that weight misperception has increased in England. Men and individuals with lower levels of education and income are more likely to underestimate their weight status and consequently less likely to try to lose weight.
