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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Ordinary (baryonic) matter make up all physical objects in existence, from stars to the cores of black holes. But until now, scientists had only been able to locate about two-thirds of the matter that theorists predict was created by the Big Bang. In new research, a multinational group of astronomers and astrophysicists pinned down the [...]
The remains of a previously unknown genus and species of gibbon, Junzi imperialis, have been found in an approximately 2,200-2,300 year-old royal tomb in Shaanxi province, China. Gibbons (family Hylobatidae) have played an important role in Chinese culture for thousands of years, being present in ancient literature and art. Their perceived ‘noble’ characteristics made them [...]
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.
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.
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.
