"In his February 5,2019, State of the Union Address, President Trump promised to reinforce national efforts to end the US HIV/AIDS epidemic by 2030. However, the national public health agenda has neglected the accelerating HIV/AIDS crisis in Hispanic/Latino communities. Progress in the fight against HIV is re?ected in aggregate data for the United States, but data released by the Centers for Disease Control and Prevention (CDC) raise alarming concerns about widening, yet largely unrecognized, HIV infection disparities among Hispanics/Latinos."
Scientists have long theorized that the energy stored in the atomic bonds of nitrogen could one day be a source of clean energy. But coaxing the nitrogen atoms into linking up has been a daunting task. Researchers at Drexel University's C&J Nyheim Plasma Institute have finally proven that it's experimentally possible - with some encouragement from a liquid plasma spark.
An international research team including Iyad Rahwan, Director of the Center for Humans and Machines at the Max Planck Institute for Human Development in Berlin, sought to find out whether cooperation between humans and machines is different if the machine purports to be human. They carried out an experiment in which humans interacted with bots. In the study now published in Nature Machine Intelligence, the scientists show that bots are more successful than humans in certain human-machine interactions -- but only if they are allowed to hide their non-human identity.
A KAIST research team has developed a gallium-based metal complex enabling the rapid chiral analysis of alcohols. A team working under Professor Hyunwoo Kim reported the efficient new alcohol analysis method using nuclear magnetic resonance (NMR) spectroscopy in iScience.
The Chinese government may have been systematically misreporting the number of organs it claims it has voluntarily collected since 2010, according to new research published in BMC Medical Ethics.
In 2015 China promised the world they would no longer source organs from prisoners - their almost sole source previously.
The study, led by PhD scholar Matthew Robertson from The Australian National University (ANU), used statistical forensics on official Chinese datasets.
Some molecules can exist in two mirror-image forms, similar to our hands. Although such so-called enantiomers have almost identical physical properties, they are not the same. The fact that they behave to each other like image and mirror image is called chirality (from the Greek cheiro for hand). In nature, however, often only one enantiomer exists, for example in amino acids, DNA or sugars. The enzymes that produce these molecules are themselves chiral and therefore only produce one type of enantiomer.
Axeheads made out of Alpine rocks had strong social and economic symbolic meaning in the Neolithic, given their production and use value. Their resistance to friction and breakage, which permitted intense polishing and a re-elaboration of the rocks, gave these artefacts an elevated exchange value, key to the formation of long-distance exchange networks among communities of Western Europe. Communities who had already begun to set the value of exchange of a product according to the time and effort invested in producing them.
HSE University economists analyzed what banks performed best on the Russian market from 2004 to 2015 - state, private, or foreign -owned ones. They found out that during stable economic and political periods, foreign- owned banks tend to take the lead, while during a crisis period, such as from 2008 to 2013, state -owned banks outperformed them.
At the 2016 Rio Olympics, Michael Phelps was caught on camera glaring as he prepared for the men's 200-meter butterfly final. The look, popularly known as Phelps face, became an example of a concept that has long been familiar in sports: the game face.
But could putting on a serious face in preparation for competition actually impact performance? According to a new study published in Stress and Health by experimental psychology researchers at UT, there may be substance to game face.
Messenger RNA transmits genetic information to the proteins, and microRNA plays a key role in the regulation of gene expression. Scientists from the Moscow Institute of Physics and Technology and the Research Centre for Medical Genetics have described the complex interactions between these two and other kinds of human RNA. The paper was published in Frontiers in Genetics.
What are microRNA and Argonaute proteins?
Washington, DC, November 14, 2019- A study in the Journal of the American Academy of Child and Adolescent Psychiatry (JAACAP), published by Elsevier, reports that home-visiting by trained community workers during and after pregnancy can improve mother-child interactions in the first years of life.
UNIVERSITY PARK, Pa. -- Despite increasing support for the rights of people in the LGBTQ+ community, discrimination remains a critical and ongoing issue for this population, according to researchers.
In a recent study, researchers found that adults who identified as gay, lesbian or bisexual -- as well as people who reported same-sex attraction or same-sex sexual partners, referred to as sexual minorities -- experienced discrimination and victimization at different rates across age.
Feelings of neighborhood pride, interactions with tourists and a community's laws can all influence how neighbors feel about short-term vacation rentals.
These interactions can change from neighborhood to neighborhood and can offer insight into how to craft local ordinances governing these types of vacation rentals, according to a newly published study conducted at the University of Georgia.
A new study from researchers at the Johns Hopkins Bloomberg School of Public Health found that in several cities and counties the proportion of high-schoolers who have ever used heroin or misused prescription opioids is much higher than the national average.
The study found that about one in every five white or Latina high school girls in Duval County, Florida, which includes Jacksonville, have misused prescription opioids, while more than 10 percent of Latino high school boys in Duval County and black high school boys in Baltimore, Maryland, have used heroin at least once.
New Rochelle, NY, November 14, 2019--A novel method uses subcellular fractionation to quantify label-free antisense oligonucleotides (AONs)- designed to silence targeted genes - that have crossed into the nucleus of a cell, where they can exert their effects. Researchers used this method to correlate nuclear entry of several AON molecules with target gene knockdown and they report their results in Nucleic Acid Therapeutics, a peer-reviewed journal from Mary Ann Liebert, Inc. publishers.
