Tropical Storm Krosa had recently developed into a tropical storm when the GPM satellite passed overhead and found heavy rainfall. Fortunately, the storm was over open waters.
Krosa formed on August 5 as the eleventh tropical depression of the Northwestern Pacific Ocean typhoon season. On August 6 by 5 a.m. EDT (0900 UTC) it had become a tropical storm and was re-named Krosa.
The prostates of older mice contain more luminal progenitor cells -- cells capable of generating new prostate tissue -- than the prostates of younger mice, UCLA researchers have discovered.
The observation, published in Cell Reports, helps explain why, as people age, the prostate tends to grow, leading to an increased risk for prostate cancer and other conditions.
It may be possible to reach new levels of miniaturization, speed, and data processing with optical quantum computers, which use light to carry information. For this, we need materials that can absorb and transmit photons. In the journal Angewandte Chemie, Chinese scientists have introduced a new strategy for constructing photonic heterostructure crystals with tunable properties. Using a crystalline rod with stripes that fluoresce in different colors, they have developed a prototype of a logic gate.
GALVESTON, Texas -Researchers from The University of Texas Medical Branch at Galveston have discovered a new potential medication that works with an HIV-infected person's own body to further suppress the ever present but silent virus that available HIV treatments are unable to combat.
Although the potential new drug could complement the current HIV anti-retroviral therapy (ART) medications, it may also be possible that it could lead to HIV remission without a lifetime of taking ART medications. The findings are published in the Journal of Clinical Investigation.
Under the watchful eyes of five high-speed cameras, a small, pale-blue bird named Gary waits for the signal to fly. Diana Chin, a graduate student at Stanford University and Gary's trainer, points her finger to a perch about 20 inches away. The catch here is that the perch is covered in Teflon, making it seemingly impossible to stably grasp.
Gary's successful touchdown on the Teflon - and on other perches of varying materials - is teaching researchers how they might create machines that land like a bird.
In recent years, efforts to understand the workings of the mind have taken on new-found urgency. Not only are psychological and neurological disorders -- from Alzheimer's disease and strokes to autism and anxiety -- becoming more widespread, new tools and methods have emerged that allow scientists to explore the structure of, and activity within, the brain with greater granularity.
Salinity gradient energy is recognized as a promising candidate for the substitution of the traditional fossil fuels. Recently nanofluidic salinity gradient energy harvesting via ion channels or membranes has drawn increasing concerns due to the advances in materials science and nanotechnology, which could offer much higher power density than the macro reverse electrodialysis systems, indicating its potential to harvest the blue energy (about 1.4-2.6 TW) released by mixing seawater and river water as well as enhancing the power extracted for membrane-based osmotic heat engines.
A research team of fusion scientists succeeded in proving that ions can be heated by plasma oscillations driven by high-energy particles. This has been confirmed by performing a large-scale simulation with a newly developed hybrid-simulation program that links calculations for plasma oscillations, high-energy particles and ions. This research will accelerate studies of plasma self-heating for realizing fusion energy.
A team of scientists from the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg and the Department of Physics at ETH Zurich in Switzerland, together with the Center for Computational Sciences of University of Tsukuba, has unraveled the light-induced electron-localization dynamics in transition metals at the attosecond timescale. The team investigated for the first time the many-body electron dynamics in transition metals before thermalization sets in. Their work has now appeared in Nature Physics.
A phenomenon that makes coral spawn more than once a year is improving the resilience of the Great Barrier Reef.
The discovery was made by University of Queensland and CSIRO researchers investigating whether corals that split their spawning over multiple months are more successful at spreading their offspring across different reefs.
Dr Karlo Hock, from UQ's School of Biological Sciences, said coral mass spawning events are one of the most spectacular events in the oceans.
"They're incredibly beautiful," Dr Hock said.
Trees are seen as saviors in an era of climate change. Via their leaves, they absorb carbon dioxide and transform the greenhouse gas into oxygen and biomass. According to estimates by the International Panel on Climate Change (IPCC), the Amazon rainforests absorb a quarter of the carbon dioxide that is released each year from the combustion of fossil fuels. To date, global climate models have assumed that this absorption capacity will also remain constant in the future.
Nickel is one of the most abundant elements on earth. It is hard, yet malleable, magnetic at room temperature, and a relatively good conductor of electricity and heat. Most notably, nickel is highly corrosion resistant, which provides for a variety of uses by industry.
However, a surprising discovery by a team of researchers at Texas A&M University has found that nickel not only corrodes, but does so in a way that scientists least expected.
Some insects have the ability to manipulate plants to produce new organs known as galls, which manifest as abnormal growths on leaves, branches, or twigs. These galls provide insects and their offspring with food and shelter. Insects are also able to redirect the plant's nutrients, such as sugar, toward their galls, sometimes leaving the plant malnourished.
DALLAS, Aug. 6, 2019 - Blood pressure monitoring might one day become as easy as taking a video selfie, according to new research in Circulation: Cardiovascular Imaging, an American Heart Association journal.
Transdermal optical imaging measures blood pressure by detecting blood flow changes in smartphone-captured facial videos. Ambient light penetrates the skin's outer layer allowing digital optical sensors in smartphones to visualize and extract blood flow patterns, which transdermal optical imaging models can use to predict blood pressure.
Scientists at the University of Leeds have created a new form of gold which is just two atoms thick - the thinnest unsupported gold ever created.
The researchers measured the thickness of the gold to be 0.47 nanometres - that is one million times thinner than a human finger nail. The material is regarded as 2D because it comprises just two layers of atoms sitting on top of one another. All atoms are surface atoms - there are no 'bulk' atoms hidden beneath the surface.
