Hollow multishelled structures (HoMSs), with relatively isolated cavities and hierarchal pores in the shells, are structurally similar to cells. They can be used as a carrier for antibacterial agent.
A recent research led by Prof. WANG Dan and Prof. ZHANG Suojiang from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences studied the diffusion and transport mechanism of antimicrobial molecules through HoMSs, and discovered that the unique temporal-spatial order property of HoMSs can realize the sequential drug release for the first time.
Dilated cardiomyopathy (DCM) is a leading cause of heart failure, affecting 1 in 250 people. The disease is characterised by an increase in size of the left ventricle of the heart. The stretched heart muscle is then unable to pump blood as effectively, which can lead to irregular heartbeat, heart valve problems, and ultimately heart failure. As the leading cause of heart failure, DCM is the most common reason for carrying out a heart transplant, which is only offered in end-stage heart failure when all other treatment options and lifestyle changes have failed.
An isolated population of the rarest Palaearctic butterfly species: the Arctic Apollo (Parnassius arcticus), turned out to be a new to science subspecies with distinct looks as well as DNA. Named Parnassius arcticus arbugaevi, the butterfly is described in a recent paper, published in the peer-reviewed, open-access scientific journal Acta Biologica Sibirica.
TORONTO, September 8, 2020 - Across 5 days in August (3rd-7th), scientists from around the world gathered virtually to present and discuss new information on the role of the chemical senses in disease, nutrition, and social interactions in humans and animals.
Carbon dioxide (CO(2)) is not just an undesirable greenhouse gas, it is also an interesting source of raw materials that are valuable and can be recycled sustainably. In the journal Angewandte Chemie, Spanish researchers have now introduced a novel catalytic process for converting CO(2) into valuable chemical intermediates in the form of cyclic carbonates.
Physicists from MIPT and the Russian Quantum Center, joined by colleagues from Saratov State University and Michigan Technological University, have demonstrated new methods for controlling spin waves in nanostructured bismuth iron garnet films via short laser pulses. Presented in Nano Letters, the solution has potential for applications in energy-efficient information transfer and spin-based quantum computing.
Species typically evolve over the course of eons, but researchers at the University of Minnesota have developed a way to do it in less than a year. A team of scientists led by Mike Smanski, Ph.D., in the College of Biological Sciences (CBS) has generated speciation events in fruit flies so that engineered strains can reproduce normally with each other, but mating with unmodified flies results in non-viable offspring.
Rice researchers find potentially useful electrical phenomenon in gold nanowires
HOUSTON - (Sept. 8, 2020) - Though the Summer Olympics were postponed, there's at least one place to see agile hurdlers go for the gold.
You just need a way to view these electron games.
In a new study, researchers at Texas A&M University have described their novel plant-based energy storage device that could charge even electric cars within a few minutes in the near future. Furthermore, they said their devices are flexible, lightweight and cost-effective.
Racial disparities among essential workers could be a key reason that Black Americans are more likely than whites to contract and die of COVID-19, according to researchers at the University of Utah. They found that Blacks disproportionately worked in nine vital occupations that increase their exposure to SARs-CoV-2, the virus that causes COVID-19.
Philadelphia, September 8, 2020 - Early findings from researchers at Children's Hospital of Philadelphia (CHOP) show that convalescent plasma appears to be a safe and possibly effective treatment for children with life-threatening cases of COVID-19. The results were published online Friday by the journal Pediatric Blood and Cancer.
Do the societal benefits of national monuments on US public lands outweigh the opportunity cost of forgone development and resource extraction? The answer is “yes,” according to a new study by Resources for the Future researcher Margaret Walls.
Children who are exposed to tobacco have higher rates of hospital admissions after visiting emergency departments or urgent care facilities, according to a new study by University of Cincinnati researchers.
The study, set to be published in October in Pediatric Research and currently available online, found that tobacco smoke exposure also increased the risk of pediatric patients having respiratory-related procedures performed while in the emergency department, as well as medications prescribed.
Formerly a typhoon, Tropical Storm Haishen made landfall in South Korea on Monday, Sept. 2 and continued moving north toward China. NASA's Aqua satellite provided an infrared view of Haishen as a typhoon before landfall and a visible image after landfall as an extra-tropical storm.

NASA-NOAA's Suomi NPP satellite provided forecasters with a visible image of the latest tropical cyclone in the North Atlantic hurricane season. Tropical Storm Rene was bringing tropical-storm force winds and rain to the Cabo Verde Islands.
Cabo Verde, also known as Cape Verde, is a country consisting of a chain of islands, located about 385 miles (620 km) off the west coast of Africa.
