People in what is now Washington State were smoking Rhus glabra, a plant commonly known as smooth sumac, more than 1,400 years ago.
The discovery, made by a team of Washington State University researchers, marks the first-time scientists have identified residue from a non-tobacco plant in an archeological pipe.
DURHAM, N.C. -- The thin, slippery layer of cartilage between the bones in the knee is magical stuff: strong enough to withstand a person's weight, but soft and supple enough to cushion the joint against impact, over decades of repeat use. That combination of soft-yet-strong has been hard to reproduce in the lab. But now, Duke University researchers say they've created an experimental gel that's the first to match the strength and durability of the real thing.
The study, published recently in Circulation Research and led by a team from King's College London, has investigated how nitrogen dioxide can impact the cardiovascular system.
The study examined the blood chemistry and cardiovascular changes of 12 healthy volunteers. They sat next to a domestic gas cooker for ninety minutes followed by ninety minutes with normal background nitrogen levels. On another occasion, the volunteers were exposed to normal background nitrogen dioxide levels for three hours.
Marina Domracheva and Sofya Kulikova, researchers from HSE University's campus in Perm, have discovered a new approach to analyse the perceived similarity of food products, based on electroencephalography (EEG) signals. They note that the power of gamma oscillations can reflect similarities in a cross-modal approach. Their paper was published in the journal Food Quality and Preference.
Analysis from the University of Surrey suggests that the economies of countries such as America, the United Kingdom and Germany should prepare for a long slow recovery with prolonged periods of instability.
SAN ANTONIO - The majority of children with COVID-19 in 26 countries fared well clinically compared to adults during the first four months of the pandemic, a newly released study shows.
Researchers from the Long School of Medicine at The University of Texas Health Science Center at San Antonio prepared the study, which is the largest systematic review to date of children and young adults with COVID-19. EClinicalMedicine, a journal of The Lancet, on June 26 published the results, which cover studies published between Jan. 24 and May 14.
Among the findings:
Leipzig/Dresden. In connection with the effects of the COVID-19 pandemic, satellite measurements made headlines showing how much the air pollutant nitrogen dioxide (NO2) had decreased in China and northern Italy. In Germany, traffic density is the most important factor.
The nature of the sediments on the Basque continental shelf is very heterogeneous. From the point of view of distribution, two clearly differentiated sectors can be picked out in terms of grain size. "In the area of Bizkaia medium to coarse-sized sands predominate, whereas on the coast of Gipuzkoa there is a predomination of deposits of very fine sand, silts and clays, currently known as the Basque Mud Patch (BMP)," explained Maria Jesus Irabien, researcher in the UPV/EHU's Department of Mineralogy and Petrology.
New Orleans, LA - A paper published by Paul Fidel, Jr., PhD, Professor and Director of the Center of Excellence in Oral and Craniofacial Biology and Associate Dean for Research at LSU Health New Orleans School of Dentistry, and Mairi Noverr, PhD, Professor of Microbiology & Immunology at Tulane University School of Medicine in New Orleans, suggests that live attenuated vaccines such as MMR (measles, mumps and rubella) may prevent the severe lung inflammation and sepsis associated with COVID-19 infection. The paper was published online in mBio
In a new study of axion motion, researchers propose a scenario known as "kinetic misalignment" that greatly strengthens the case for axion/dark matter equivalence. The novel concept answers key questions related to the origins of dark matter and provides new avenues for ongoing detection efforts. This work, published in Physical Review Letters, was conducted by researchers at the Institute for Advanced Study, University of Michigan, and UC Berkeley.
Announcing a new article publication for BIO Integration journal. In this research article the authors Vered Aharonson, Nabeel Seedat, Simon Israeli-Korn, Sharon Hassin-Baer, Michiel Postema and Gilad Yahalom from the University of the Witwatersrand, Johannesburg, South Africa, Tel Aviv Academic College of Engineering, Tel Aviv, Israel, Chaim Sheba Medical Center, Tel Aviv, Israel and Tel Aviv University, Israel consider automated stage discrimination of Parkinson's Disease.
KINGSTON, R.I. - June 26, 2020 -- In a new study, scientists from around the world - including a professor at the University of Rhode Island - warn that the threats posed by invasive alien species are increasing. They say that urgent action is required to prevent, detect and control invaders at both local and global levels.
Alien species are plants, animals and microbes that are introduced by people, accidentally or intentionally, into areas where they do not naturally occur. Many of them thrive, spreading widely with harmful effects on the environment, economy, or human health.
SALT LAKE CITY, UT - Over the last three decades, colorectal cancer survival in the United States has improved significantly. But in young people--particularly men diagnosed with colorectal cancer before age 50--incidence and mortality due to colorectal cancer are on the rise. Even among patients with early-stage colorectal cancer, racial disparities have grown more pronounced, with survival after colorectal cancer diagnosis poorer among African Americans compared with whites.
The brains of millions of people suffering from Alzheimer´s disease (AD) are slowly and inescapably being depleted of neurons, which leads to the characteristic loss of memory and cognitive function associated with this condition. However, the cause of neuronal death is still unknown. The treatments available are aimed at slowing down the development of dementia and only help to improve quality of life for short periods. Therefore, treatments to actually cure AD are an unmet medical need.
BOZEMAN -- How many people in the U.S. have had COVID-19? Using a database of information collected after the 2009 H1N1 outbreak, a Montana State University researcher is helping develop a better understanding of the spread of the novel coronavirus.
