The genetic mechanisms underlying the development of the coronary atherosclerosis has been investigated. Results show potential value for estimating the risk of the myocardial infarction, say researchers.
Scientists have determined that one prominent long non-coding RNA may be a 'red herring,' with no evident biological role to play -- whereas the DNA from which it originates does perform an important function, as an 'enhancer' that stimulates the expression of an important protein-coding gene nearby.
Harmful algal blooms dangerous to human health and the Lake Erie ecosystem--such as the one that shut down Toledo's water supply for two days in 2014--could become a problem of the past. Scientists have reported on approaches to reduce harmful algal blooms on Lake Erie.
Women were five times as likely to develop cancer if they had a higher percentage of Ki67, a molecular marker that identifies proliferating cells, in the cells that line the mammary ducts and milk-producing lobules, researchers have shown. These cells, called the mammary epithelium, undergo drastic changes throughout a woman's life, and the majority of breast cancers originate in these tissues.
While stem cells have shown promise for treating brain regions damaged by cancer radiation treatments, researchers have found that microscopic vesicles isolated from these cells provide similar benefits without some of the risks associated with stem cells.
Physicists have combined light and sound to control electron states in an atom-like system, providing a new tool in efforts to move toward quantum-computing systems.
A new window has been opened into the climate history of the Arctic Ocean. Using unique sediment samples from the Lomonosov Ridge, the researchers found that six to 10 million years ago the central Arctic was completely ice-free during summer and sea-surface temperature reached values of 4 to 9 degrees Celsius.
A research team has achieved unparalleled levels of control over the angular momentum (AM) of light in an integrated nanophotonic chip. The work leads the way for compact on-chip AM applications like ultra-high definition display, ultra-high capacity optical communication and ultra-secure optical encryption, and could also be used to help scientists better understand the evolution and nature of black holes.
Engineers have shown a new approach for making transistors and other electrical devices: sequentially depositing their components in the form of liquid nanocrystal 'inks.'
Models that aim to predict human-induced global average temperature rise have been underestimating important contributions from clouds, causing projections to be lower than what actually might occur, at least in some simulations, a new study suggests.
In an international first, a research team of experimental physicists has measured long-range magnetic interactions between ultracold particles confined in an optical lattice. Their work introduces a new control knob to quantum simulation.
Researchers report that volunteer canvassers -- both transgender and not -- reduced voters' prejudice against transgender people. Last year the researchers triggered fierce debate about the need for transparency in social science research when they raised doubts about a now-retracted study of the Los Angeles LGBT Center's door-to-door canvassing on gay marriage by other researchers that appeared in Science. They discovered irregularities in that study's data while conducting this follow-up study.
Can a flow of information across Twitter signal when a momentous event is about to occur? Scientists developed a method to find out. Their findings represent an initial step in constructing models to detect trouble before it's too late.
Some top soccer players are under-performing because of worries about gambling losses, according to new research.
An interdisciplinary team of researchers has successfully measured both pH and carbonate ion concentration directly inside the calcifying fluid found in coral, an important development in the study of how ocean acidification will affect marine calcifying organisms such as corals and shellfish.
Researchers developed a theoretical model that considers the strategic interaction between a daily deal website, a merchant and consumers. They found that by providing sales information, daily deal websites gained advantages over traditional coupon mailers, while also allowing merchants to attract new customers.
People gauge others' trustworthiness based on their moral judgments, new research shows. People who are seen as holding to moral absolutes are more trusted and more valued as social partners, the study indicates.
Researchers have shed new light on how the structure of regulatory sequences in DNA is packaged in a cell. This work has implications for better understanding the role that gene sequences called enhancers play within our DNA for governing gene activity.
A detailed molecular analysis of the embryo's first week of development has been conducted by scientists. Their results show that there are considerable differences in embryonic development between humans and mice, which is the most common organism of study in this field.
Fruit flies live 16 percent longer than average when given low doses of the mood stabilizer lithium, according to a study. How lithium stabilizes mood is poorly understood but when the scientists investigated how it prolongs the lives of flies, they discovered a new drug target that could slow aging -- a molecule called glycogen synthase kinase-3 (GSK-3).
