Crystallization is one of the most fundamental processes found in nature - and it's what gives minerals, gems, metals, and even proteins their structure.
In the past couple of decades, scientists have tried to uncover how natural crystals self-assemble and grow - and their pioneering work has led to some exciting new technologies - from the quantum dots behind colorful QLED TV displays, to peptoids, a protein-mimic that has inspired dozens of biotech breakthroughs.
During the last twenty years, the trading in stock markets has undergone significant changes. Researchers from the University of Turku and the University of Palermo have investigated the role of high-frequency traders in the markets.
Technological evolution and innovations both in the technology used by stock exchanges and the resources of the traders using their services have made faster trading possible. As a result, high-frequency trading in sub millisecond scale has increased.
HOUSTON - (June 29, 2021) - The story of halichondrin B, an inspirational molecule obtained from a marine creature, goes back to the molecule's discovery in an ocean sponge in 1986.
Though it has been replicated in the laboratory several times before, new work by Rice University chemists could make halichondrin B and its naturally occurring or designed variations easier to synthesize.
In cancer therapy, the effectiveness of an approach is determined by its ability to preserve the non-cancerous cells. Simply put, the higher the collateral damage, the greater are the side-effects of a therapy. An ideal situation is where only the cancer cells can be targeted and destroyed. In this regard, photothermal therapy--an approach in which cancer cells infused with gold nanoparticles can be heated up and destroyed using near-infrared (NIR) light that is strongly absorbed by the gold nanoparticles--has emerged as a promising strategy due to its minimally invasive nature.
Phase 1/2 clinical trial of CoronaVac in 550 children and adolescents aged 3-17 years in China suggests two doses of the vaccine are safe and generate a strong antibody response.
First published data on safety and immune response generated by a COVID-19 vaccine in children as young as 3-years-old supports use of CoronaVac - which was recently approved for emergency use in China among children over 3-years-old - in further studies to inform immunisation strategies.
According to the World Health Organization, about 785 million people around the world lack a clean source of drinking water. Despite the vast amount of water on Earth, most of it is seawater and freshwater accounts for only about 2.5% of the total. One of the ways to provide clean drinking water is to desalinate seawater.
CORVALLIS, Ore. - Research by a graduate student in Oregon State University's College of Science has upended the conventional wisdom that for a century has incorrectly guided the study of a toad listed as endangered in part of its range.
Anne Devan-Song used spotlighting - shining a light in a dark spot and looking for eye reflections - to find large numbers of the eastern spadefoot toad. The study illustrates how confirmation bias - a tendency to interpret new information as ratification of existing theories - can hamper discovery and the development of better ones.
Neoadjuvant immune checkpoint blockade (ICB) is a promising treatment for melanoma and other cancer types, and has recently been shown to provide a modest survival benefit for patients with recurrent glioblastoma. To improve the treatment efficacy, researchers are looking for vulnerabilities in surgically removed glioblastoma tissues, but this has been difficult due to the vast differences within the tumor and between patients.
Scientists of Tomsk Polytechnic University jointly with colleagues from Spanish universities have offered a simple method how to enhance the responsivity of terahertz radiation detectors by 3.5 folds using a small Teflon cube. The 1 mm cube must be put on the surface of the detector without changing the inner design of the detector.
When it comes to career aspirations for teenagers, a University of Houston psychology researcher believes it's best to shoot for the moon, so you can at least land in the stars. The truth is the moon may sometimes be unreachable.
In the Journal of Career Assessment, Kevin Hoff, assistant professor of psychology, reports the existence of important discrepancies between young people's dream jobs and employment realities.
Scientists from Helmholtz Zentrum München revise the current textbook knowledge about gastrulation, the formation of the basic body plan during embryonic development. Their study in mice has implications for cell replacement strategies and cancer research.
CHAMPAIGN, Ill. -- Researchers report that small quantities of useful molecules such as hydrocarbons are produced when carbon dioxide and water react in the presence of light and a silver nanoparticle catalyst. Their validation study - made possible through the use of a high-resolution analytical technique - could pave the way for CO2-reduction technologies that allow industrial-scale production of renewable carbon-based fuels.
WHO Frank A. J. L. Scheer, PhD, MSc, Neuroscientist and Marta Garaulet, PhD, Visiting Scientist, both of the Division of Sleep and Circadian Disorders, Departments of Medicine and Neurology, Brigham and Women's Hospital. Drs. Scheer and Garaulet are co-corresponding authors of a new paper published in The FASEB Journal.
In many situations, heart muscle cells do not respond to external stresses in the same ways that skeletal muscle cells do. But under some conditions, heart and skeletal muscles can both waste away at fatally rapid rates, according to a new study led by experts at Cincinnati Children's.
Philadelphia, June 24, 2021 - Women with depression and other mood disorders are generally advised to continue taking antidepressant medications during pregnancy. The drugs are widely considered safe, but the effect of these medications on the unborn fetus has remained a topic of some concern.
