Visible imagery from NASA's Aqua satellite showed Tropical Cyclone 04W had been torn apart from wind shear in the Northwestern Pacific Ocean.
On Saturday, June 29, Tropical Storm 04W developed east of the Philippines and was moving toward the northwest. 04W formed near 15.3 north latitude and 130.7 east longitude, about 564 miles east of Manila, Philippines. At that time, 04W had maximum sustained winds near 35 knots (40 mph)
Tropical Storm Barbara formed on Sunday, June 30 in the Eastern Pacific Ocean over 800 miles from the coast of western Mexico. The Global Precipitation Measurement mission or GPM core satellite passed over the storm and measured the rate in which rain was falling throughout it.
Barbara formed as a tropical storm around 11 a.m. EDT (1500) on June 30, and slowly intensified.
AMES, Iowa - Jigang Wang patiently explained his latest discovery in quantum control that could lead to superfast computing based on quantum mechanics: He mentioned light-induced superconductivity without energy gap. He brought up forbidden supercurrent quantum beats. And he mentioned terahertz-speed symmetry breaking.
Then he backed up and clarified all that. After all, the quantum world of matter and energy at terahertz and nanometer scales - trillions of cycles per second and billionths of meters - is still a mystery to most of us.
A new membrane made from water-wet materials has specially designed gas-entrapping pores that allow it to simultaneously separate hot, salty from cool, pure water while facilitating the transfer of pure vapor from one side to the other. This principle, designed by KAUST researchers, could lead to greener, cheaper desalination membranes.
The use of electric propulsion for raising satellites into geostationary orbit can result in significant solar cell degradation according to a new study. The extended journey results in greater exposure to the damaging effects of space weather. Understanding the size of this risk is essential for commercial operators to take steps to mitigate the effects and protect their assets.
Machines are getting cozy with our cells. Embeddable sensors record how and when neurons fire; electrodes spark heart cells to beat or brain cells to fire; neuron-like devices could even encourage faster regrowth after implantation in the brain.
Soon, so-called brain-machine interfaces could do even more: monitor and treat symptoms of neurological disorders like Parkinson's disease, provide a blueprint to design artificial intelligence, or even enable brain-to-brain communication.
The Powering Past Coal Alliance, or PPCA, is a coalition of 30 countries and 22 cities and states, that aims to phase out unabated coal power. But analysis led by Chalmers University of Technology, Sweden, published in Nature Climate Change, shows that members mainly pledge to close older plants near the end of their lifetimes, resulting in limited emissions reductions. The research also shows that expansion of the PPCA to major coal consuming countries would face economic and political difficulties.
In 2007, Patrice Cani (FNRS-WELBIO researcher) and his team at the Louvain Drug Research Institute of University of Louvain, in close collaboration with Willem de Vos, professor at UWageningen, discovered the beneficial effects of an intestinal bacteria, Akkermansia muciniphila (1), able to moderate the development of obesity and type 2 diabetes, in mice.
On October 19, 2017, astronomers discovered the first known interstellar object to visit our solar system. First spotted by the Panoramic Survey Telescope and Rapid Response System 1 (PanSTARRS1) telescope located at the University of Hawaii's Haleakala Observatory, the object defied easy description, simultaneously displaying characteristics of both a comet and an asteroid.
From a biological standpoint, the earliest stages of life are the most mysterious. A developing human embryo undergoes a flurry of rapid changes, and these changes are exceedingly difficult to study because they transpire within the confines of a womb.
Researchers at the Center for Quantum Nanoscience (QNS) within the Institute for Basic Science (IBS) at Ewha Womans University have made a major scientific breakthrough by performing the world's smallest magnetic resonance imaging (MRI). In an international collaboration with colleagues from the US, QNS scientists used their new technique to visualize the magnetic field of single atoms.
Lifestyle changes can reduce our greenhouse gas emissions and help protect nature. While some actions offer great potential, some aren't as effective as we think and may even require more land and water, such as shifting to renewable energy.
We need to change our lifestyle if we want to make a dent in greenhouse gas emissions in Europe. But not all changes proposed in the name of climate mitigation are for the better, according to research from NTNU and others.
"Bark beetles lay waste to forests" - "Climate change sends beetles into overdrive" - "Bark beetles: can the spruce be saved?": These newspaper headlines of the past weeks covered the explosive growth of bark beetle populations and its devastating impact on timberlands. The problem is not limited to Germany. A comparable situation is encountered in many forests across Central Europe and North America. The consequences of this major infestation are massive: In 2018, the beetles were responsible for ruining around 40 million cubic metres of wood just in Central Europe.
Solar cells are currently the world's most talked-about renewable energy source, and for any future sustainable energy system, it is crucial to know about the performance of photovoltaic systems at local, regional and global levels. Danish researchers have just set up an historically accurate model, and all the data has been made available for anyone who wants to use it.
EAST LANSING, Mich. - Pictures of the earth's water cycle used in education and research throughout the world are in urgent need of updating to show the effects of human interference, according to new analysis by an international team of hydrology experts.
Leaving humans out of the picture, the researchers argue, contributes to a basic lack of awareness of how humans relate to water on Earth - and a false sense of security about future availability of this essential and scarce resource.
