While there has been an increased focus on person-centered models of care transition for cognitively intact older adults from hospital to home, little is known about the core elements of successful transitions in care specifically for persons with dementia.
Researchers have developed a new flexible sensor with high sensitivity that is designed to perform variety of chemical and biological analyses in very small spaces.
An international collaboration has discovered that early humans in eastern Africa had--by about 320,000 years ago--begun trading with distant groups, using color pigments and manufacturing more sophisticated tools than those of the Early Stone Age. These behavioral innovations may represent a response to the rapid environmental and climactic changes occurring at the time.
Researchers discover evidence of the technology & behaviors linked to the emergence of human species
An anthropology professor from the George Washington University and a team of international collaborators, including scientists from the Smithsonian's National Museum of National History, have discovered that early humans in East Africa used coloring materials and obtained a range of raw materials from distant sources-- activities which imply the existence of social networks--about 320,000 years ago, much earlier than previously thought.
Scientists at the Allen Institute and the University of Washington have developed a new low-cost technique for profiling gene expression in hundreds of thousands of cells.
In a breakthrough that could lead to a new class of materials with functions found only in living systems, scientists at the University of California, Berkeley, have figured out a way to keep certain proteins active outside of the cell. The researchers used this technology to create mats that can soak up and trap chemical pollution.
An international team of researchers have sequenced DNA from individuals from Morocco dating to approximately 15,000 years ago. This is the oldest nuclear DNA from Africa ever successfully analyzed. The study, published in Science, shows that the individuals, dating to the Late Stone Age, had a genetic heritage that was in part similar to ancient Levantine Natufians and an uncharacterized sub-Saharan African lineage to which modern West Africans are genetically closest.
Researchers at Vanderbilt University Medical Center have found a way to search genetic data in electronic health records to identify undiagnosed genetic diseases in large populations so treatments can be tailored to the actual cause of the illness.
A new study reveals that preverbal infants are able to make rational deductions, showing surprise when an outcome does not occur as expected.
Efforts to sustainably manage fisheries will also reduce bycatch, a new study suggests.
After sequencing DNA in bone matter of several 15,000-year-old humans from North Africa, a region critical for understanding human history but one in which it has been challenging to connect genetic dots, researchers report a notable lack of relatedness to ancient Europeans, in their specimens - a finding that rules out hypotheses of gene flow from southern Europe into northern Africa at a particular time.
Three new studies highlight major environmental, ecological and technological changes that occurred in East Africa preceding the Middle Stone Age roughly 300,000 years ago, around the time that anatomically modern humans were evolving.
Young, resting neural stem cells in the brains of mice store large clumps of proteins in specialized cellular trash compartments known as lysosomes, researchers at the Stanford University School of Medicine have found.
Researchers at the Swiss Tropical and Public Health Institute made an important step toward deeper understanding of how malaria blood stage parasites turn the switch to become transmissible to other humans. This knowledge is fundamental for future research aiming to interrupt malaria transmission. The results will be published on Friday, March 16, 2018, in the multidisciplinary journal Science.
Scientists discovered that early humans in East Africa had -- by about 320,000 years ago -- begun trading with distant groups, using color pigments and manufacturing more sophisticated tools than those of the Early Stone Age, tens of thousands of years earlier than previous evidence has shown in eastern Africa. As earthquakes remodeled the landscape and climate fluctuated between wet and dry conditions, technological and social innovation would have helped early humans survive unpredictable conditions.
More than 500 years ago, Leonardo da Vinci sketched what he called 'la turbolenza,' comparing chaotic swirls atop flowing water to curly human hair. It turns out those patterns influence myriad phenomena, from the drag on an airplane's wings and the formation of Jupiter's red spot to the rustling of tree leaves.
Interactions between Chlamydia trachomatis proteins and host cell proteins help determine whether the bacterium leaves an infected cell via breakdown of the cellular membrane (lysis) or in a membrane-bound package, according to new research published in PLOS Pathogens by Phu Hai Nguyen of the National Institutes of Health, US, and colleagues.
The burden of yellow fever in any given area is known to be heavily dependent on climate, particularly rainfall and temperature which can impact both mosquito life cycle and viral replication. Now, researchers from Imperial College London and the World Health Organization (WHO) have developed a new model to quantify yellow fever dynamics across Africa using not only annual averages of these climatic measures, but seasonal dynamics. Their work is described in PLOS Neglected Tropical Diseases.
University of Houston scientists are helping to develop a technology that could hold the key to unraveling one of the great mysteries of science: what constitutes dark matter?
Neuroscientists at the Sainsbury Wellcome Centre have identified a circuit in the primary visual cortex (V1) of the brain that integrates head- and visual-motion signals. The study, published today in Neuron, elucidates the mechanisms by which visual and vestibular inputs to the brain sum together to enable appropriate behavioural responses.
