A research team lead by MIMS/SciLifeLab research group leader Jonas Barandun, Umeå University, Sweden, uses cryo-electron microscopy to provide near atomic details of the smallest known eukaryotic cytoplasmic protein synthesis machine, the microsporidian ribosome.
Our eyes -- the windows to the soul -- need constant care, and as we age, they sometimes also need significant repair.
The panes of these windows -- the corneas -- are transparent tissues that have been the focus of some of the oldest and most common transplantation surgeries. Now thanks to researchers in Kyoto, some such transplants may become even safer.
Think twice before adding that extra kick of chili sauce or chopped jalapeno to your meal. New research involving the University of South Australia shows a spicy diet could be linked to dementia.
A 15-year study of 4582 Chinese adults aged over 55 found evidence of faster cognitive decline in those who consistently ate more than 50 grams of chili a day. Memory decline was even more significant if the chili lovers were slim.
Cells assemble dynamically: their components are continuously exchanging and being replaced. This enables the structures to adapt easily to different situations, and by rearranging the components to respond to stimuli faster, to renew or to form just on demand. The microtubules, a scaffold structure made of protein fibers that can be found in the cytoplasm of the cells of algae, plants, fungi, animals and humans, are one such dynamic mesh.
Illumination consumes more than 20 percent of electricity. Thus, finding an efficient, stable, single-phase warm white-light material is very important. Lead hybrid perovskites have drawn interest for excellent photoelectric performance and simple synthesis. Lead perovskites with white-light emission have been studied, but the photoluminescence quantum efficiencies (PLQEs) are low. However, the large-scale application of lead perovskites is hindered by toxicity and instability.
The efficient extraction of oil and gas from within the Earth's crust requires accurate images of subsurface rock structures. Some materials are hard to capture, so KAUST researchers have developed a computational method for modeling large accumulations of subsurface salt, a challenging material to derive accurately from seismic imaging data.
Pneumonia resulting from exposure to Legionella - although uncommon and affecting only 1 in 100,000 in Europe - has a higher than 10% fatality rate. The pathogenic bacterium Legionella pneumophila has more than 300 toxins that it uses to infect humans. Once the aerosols containing the bacteria are inhaled, Legionella enters the lungs where it starts infecting human cells, causing pneumonia.
A gamelike intervention developed by school psychology researchers in UT's College of Education, Health, and Human Sciences may help reduce hallway disruptions among elementary school children.
The intervention rewards classes of students for quickly transitioning from one room or activity to another. When implemented with three classes of students from grades one through six at a summer school program, disruptions during class transitions were reduced by up to 74 percent.
After a cancer patient receiving an immunotherapy developed encephalitis and died 18 months into treatment, researchers at Vanderbilt-Ingram Cancer Center (VICC) investigated why the complication occurred, performing a molecular analysis of the disease's pathology and mining data to determine the incidence of similar occurrences.
DURHAM, N.C. - Continuation of community-wide HIV testing and prompt initiation of treatment as delivered in the HPTN 071 (PopART) study in South Africa and Zambia could lead to substantial reductions in new HIV cases, be cost-effective, and help to achieve the UNAIDS 2030 targets, according to projections from mathematical modelling and cost-effectiveness analyses presented today at the 10th International AIDS Society Conference on HIV Science in Mexico City (IAS 2019).
A new study using a special type of electron microscope using samples cooled to extremely cold temperatures provides critical information for drug developers seeking to reduce nausea and vomiting side effects of cancer treatments.
(BOSTON) -- A study co-authored by Boston University School of Public Health (BUSPH) researchers and published in the American Journal of Industrial Medicine finds that an injury serious enough to lead to at least a week off of work almost triples the combined risk of suicide and overdose death among women, and increases the risk by 50 percent among men.
A new paper offers fresh insight into the forces causing the world's largest ice shelf to melt.
DURHAM, N.C. - Engaging disenfranchised men who have sex with men (MSM) living with HIV in the U.S. is possible, but the best way to help them achieve and maintain viral suppression is not yet known, according to findings from HPTN 078 being reported today at the 10th IAS Conference on HIV Science (IAS 2019) in Mexico City. Although almost all participants were retained in the study, only half were virally suppressed at the end of one year.
ANN ARBOR, Mich. -- Something most parents don't want to hear from their teenager: I am not prepared to be an adult, and it's your fault.
Nearly all parents (97%) in a new national poll say they are helping their teen become more independent by using strategies like allowing them to make more choices (86%), pushing them to handle things themselves (74%) and no longer doing things for them (65%).
