The existence of language universality has been a key issue in psychology and linguistics, since the understanding of universals is crucial for the development of information perception models.
(Boston)--An improvement to the premier data visualization tool t-distributed Stochastic Neighborhood Embedding (t-SNE), called optimized-t-SNE (opt-SNE), shines new light on researchers' ability to view exactly what is in their datasets.
To understand the molecular bases of cancer, it is imperative to determine the genetic alterations responsible for the development and spread of this condition and to identify the mechanisms through which healthy cells become malignant.
As the holidays approach, people might be thinking of neat do-it-yourself woodworking projects to give as gifts. But there's often a disconnect between designing an object and coming up with the best way to make it.
Now researchers at the University of Washington have created Carpentry Compiler, a digital tool that allows users to design woodworking projects. Once a project is designed, the tool creates optimized fabrication instructions based on the materials and equipment a user has available. The team presented this research Nov. 19 at SIGGRAPH Asia in Brisbane, Australia.
It's long been known that the proteins that package DNA, like students at a high school dance, require a chaperone. But what exactly that guardian looks and acts like has been a mystery--until now.
A team of researchers at the University of Colorado Boulder has cracked the puzzle of the Facilitates Chromatin Transcription (FACT) protein structure. This protein is partly responsible for making sure everything goes smoothly and no improper interactions take place when DNA temporarily sheds and replaces its guardian proteins, or histones.
Together with colleagues from Shanghai, Brussels, Canada and the USA, researchers from the University of Bonn have uncovered the binding mechanism of an important pain receptor. The results facilitate the development of new active substances. The opioids used today to treat severe pain can be addictive and sometimes have life-threatening side effects. The results are published in the renowned journal Science Advances.
Placenta changes could mean male offspring of older mums more likely to develop heart problems in later life, rat study finds.
Changes occur in the placenta in older pregnant mothers leading to a greater likelihood of poor health in their male offspring, a study in rats has shown. Both male and female fetuses do not grow as large in older mothers, but there are sex-specific differences in changes to placental development and function. These are likely to play a central role in the increased likelihood of later-life heart problems and high blood pressure in males.
Mortality rates among working-age Americans continue to climb, causing a decrease in U.S. life expectancy that is severely impacting certain regions of the United States, according to a Virginia Commonwealth University study set to publish Tuesday in JAMA. The report, "Life Expectancy and Mortality Rates in the United States, 1959-2017," is one of the most comprehensive 50-state analyses of U.S. mortality.
Policies aimed at cutting alcohol and tobacco consumption, including the introduction of random breath testing programs and bans on cigarette advertising, have resulted in a significant reduction in Australian cancer death rates, new research shows.
The La Trobe Centre for Alcohol Policy Research (CAPR) has led the first study into how public health policies on alcohol and tobacco implemented from the 1960s affected cancer deaths in Australia.
New insight on the extinction history of a flightless seabird that vanished from the shores of the North Atlantic during the 19th century has been published today in eLife.
The findings suggest that intense hunting by humans could have caused the rapid extinction of the great auk, showing how even species that exist in large and widespread populations can be vulnerable to exploitation.
The second law of thermodynamics states that the total entropy of an isolated system always tends to increase over time until it reaches a maximum. In other words, disorganization increases without outside intervention.
Even the best electrical equipment inevitably heats up, as part of the energy that should be converted into mechanical work is dissipated in the form of heat, and supposedly inanimate objects deteriorate as time progresses but do not spontaneously regenerate.
What The Study Did: Screen time data for nearly 3,900 children were used to examine patterns of screen time use and the association with sociodemographic characteristics such as parental education levels and sex of the child.

SEATTLE - The lack of data, particularly in low- and middle-income countries, combined with the absence of international standards for data management, is hindering efforts in measuring progress toward meeting the United Nations Sustainable Development Goals (SDGs) according to a viewpoint published in the international medical journal The Lancet.
New Rochelle, NY, November 25, 2019--A new nationwide study examined the prevalence of negative behaviors that occur via digital communication, encompassing a broad definition of cyberbullying that includes both cyber-aggression and cyberbullying. The study, which assessed a national sample of New Zealanders 18-97 years of age, is published in Cyberpsychology, Behavior, and Social Networking, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.
ITHACA, N.Y. - Sometimes it's best to let the magnets do all the work.
A team led by Cornell University physics professors Itai Cohen and Paul McEuen is using the binding power of magnets to design self-assembling systems that potentially can be created in nanoscale form.
Their paper, "Magnetic Handshake Materials as A Scale-Invariant Platform for Programmed Self-Assembly," published Nov. 21 in Proceedings of the National Academy of Sciences.
