The group of Helge Grosshans characterized the "C. elegans oscillator", over 3,700 genes that are rhythmically expressed during the larval development of C. elegans. They demonstrated the coupling of the oscillator with molting and got insights into how it is wired. Their findings suggest that the oscillator functions as a developmental clock with a developmental checkpoint function.
Tropical Depression 8E developed on July 20 and quickly organized into a tropical storm. Infrared NASA satellite imagery revealed that Tropical Storm Douglas contained strong storms and showed banding of thunderstorms around its center.Tropical Depression 8E formed about 905 miles (1,460 km) southwest of the southern tip of Baja California, Mexico by 11 a.m. EDT on July 20. Within 12 hours, 8E had...
The wild spider monkeys living in a protected area near Punta Laguna, Mexico, collectively figure out good ways to divide up and conquer the forest. These monkeys live in a special type of society called a "fission-fusion" society. The group breaks up into little teams to find food—called, "foraging" in the world of ecology—but there is no "gym teacher" or "popular kid" picking teams. Rather,...
Under the Hate Crime Statistic Act, hate crimes are defined as "crimes that manifest evidence of prejudice based on race, gender and gender identity, religion, disability, sexual orientation, or ethnicity." Since the outbreak of COVID-19 in Wuhan, China, the United States has seen a surge of Asian Americans reporting racially motivated hate crimes. Earlier this month, University of Colorado Denver...
NASA-NOAA's Suomi NPP satellite passed over the Eastern Pacific Ocean and provided forecasters with a visible image of the waning Tropical Depression 7E. Wind shear and cooler waters were taking their toll on the storm.
The Nobel Foundation, which manages the Nobel Prizes, on Tuesday cancelled its traditional December banquet due to the COVID-19 pandemic, though the award ceremonies will still be held in "new forms".
Spiral galaxies such as our Milky Way can have sprawling magnetic fields. There are various theories about their formation, but so far the process is not well understood. An international research team has now analyzed the magnetic field of the Milky Way-like galaxy NGC 4217 in detail on the basis of radio astronomical observations and has discovered as yet unknown magnetic field structures. The...
Infusing prepared foods with an edible coating that contains green tea extract may lower consumers' chances of catching the highly contagious norovirus by eating contaminated food, new research suggests.
Inside your mouth right now, there is a group of bacteria whose closest relatives can also be found in the belly of a moose, in dogs, cats, and dolphins, and in groundwater deep under the Earth's surface. In a stunning discovery, scientists have found that these organisms have adapted to these incredibly diverse environments—without radically changing their genomes.
The adage 'all things in moderation' applies not to just to food and drink, but also to the legions of bacteria inside our guts helping us digest that food and drink. It turns out the rule may also extend to the lesser understood bacteriophages, which are viruses that infect the bacteria living inside us.
A research team led by Osaka University investigated the formation ages of 59 lunar craters with a diameter of approximately 20 km using the Terrain Camera (TC) onboard the lunar orbiter spacecraft Kaguya.
Over the past decades, 'storing light' has appeared as a rather controversial concept, given that a photon's inherent nature hinders its spatial confinement. The first research efforts in demonstrating optical memory functionality started as a fascinating experimental exercise, and two decades later the remarkable achievements of integrated optical memories and optical random access memories...
Topological insulators are a new phase of matter unique for their insulating bulk and perfectly conducting edges. They have been at the forefront of condensed matter physics for the past decade, and more recently inspired the emergence of topological phases in many classical-wave systems, such as photonics and acoustics. To date, all studies of topological insulators have explored systems in...
Topological insulators have been an exciting field of research with fundamental interest as well as practical applications such as robust transport of electrons and light, and topological quantum computing. The hallmark of such conventional topological insulators is the presence of conducting boundary modes which have one dimension lower than the insulating bulk system that hosts them—for...
The MIR range of the electromagnetic spectrum, which roughly covers light in the wavelength regime between 3 to 10 micrometers, coincides with the energies of fundamental molecular vibrations. Utilizing this light for the purpose of imaging can produce stills with chemical specificity, i.e. images with contrast derived from the chemical composition of the sample. Unfortunately, detecting MIR light...
Tailoring and manipulating electromagnetic wave propagation has been of great interest within the scientific community for many decades. In this context, wave propagation has been engineered by properly introducing spatial inhomogeneities along the path where the wave is traveling. Antennas and communications systems in general have greatly benefited from this wave-matter control. For instance, if...
Seasonal fluctuations drive the dynamics of many infectious diseases. For instance, the flu spreads more readily in winter. Two scientists from the University of Nantes and the CNRS in Montpellier have developed a mathematical model to predict the risk of the emergence of an epidemic, depending on the time of the year at which the pathogen is introduced.
Researchers from Kazan Federal University, Texas A&M University and Institute of Applied Physics (Russian Academy of Sciences) found ways to direct high frequency gamma radiation by means of acoustics.
When the Nobel Peace Prize was awarded to Bangladeshi economist Muhammad Yunus in 2006 for his concept of microfinance, it brought what began as a local policy experiment in the 1970s to global attention.
Further studies and debate are needed on the potential culling of generalist predators such as crows and foxes as a means of protecting Europe's ever declining number of ground-nesting birds, a new study suggests.
A UNSW report considers China's children affected by migration and climate change, and the necessary social policy reforms required to protect their rights.
The UK's universities are struggling to live up to the spirit and ambition of the Modern Slavery Act, hampered by poor oversight of their supply chains, a lack of skills and resource in supply chain management, a focus on reducing costs, and lackluster engagement from many in senior management, a new study from the University of Bath shows.
DNA methylation performs an essential function in mammalian ontogeny. It is also known that abnormalities in this process cause the development of cancers such as leukemia.
A field studying something very small is becoming very big: In the last decade, the field of nanoparticle research has exploded. At about one nanometer in size, nanoparticles are 100,000 times smaller than the width a strand of human hair and cannot be seen with the naked eye, but researchers are discovering broad uses for them in fields ranging from bioimaging to energy and the environment.
