Aging is known to involve epigenetic histone modifications, which are associated with transcriptional changes, occurring throughout the entire lifespan of an individual.
Active transportation investments offer many types of benefits related to safety, reduced greenhouse gas emissions, physical activity and the economy. Metro, Oregon's regional government for the Portland metropolitan area, wants to better understand the role of these investments in building stronger communities in their region, and in implementing the Metro 2040 Growth Concept.
Sleep is important for our health and well-being, and bad sleep can negatively impact our attention span, memory, decision-making skills, creativity and judgment.
The crystal structure of a human endogenous reverse transcriptase has similarities to HIV reverse transcriptase, a well-known tractable drug target, which will help design drugs to treat cancer and other diseases, according to a study co-authored by a Rutgers researcher.
In 2022, a Portland State University Master of Urban and Regional Planning (MURP) team made headlines with their strategies to improve safety for houseless pedestrians. Cities across the U.S. are facing alarming increases in traffic fatalities, especially among the number of pedestrians who are struck and killed by drivers. In 2021, 70 percent of all pedestrian fatalities in Portland were of...
Thin-film lithium niobate (TFLN) has recently emerged as a versatile nanophotonic platform. With the advantages of high optical confinement, enhanced light-matter interaction, and flexible dispersion control, TFLN-based periodically poled lithium niobite (PPLN) devices outperform their legacy counterparts in both non-linear optical efficiency and device footprint.
Striking a blow against a pernicious form of pollution, California lawmakers on Thursday passed the nation's most far-reaching restrictions on single-use plastics and packaging, with Gov. Gavin Newsom expected to sign the bill Thursday.
Researchers at North Carolina State University show that an important gene in maize called HPC1 modulates certain chemical processes that contribute to flowering time, and has its origins in "teosinte mexicana," a precursor to modern-day corn that grows wild in the highlands of Mexico. The findings provide insight into plant evolution and trait selection, and could have implications for corn and...
Nelumbo is a unique genus of Nelumbonaceae (lotus), which comprises two extant species: N. nucifera Gaertn. widely distributed in Asia and northern Australia, and N. lutea Pers. which is distributed in America. These two species exhibit differences in morphology, such as plant size, leaf shape, petal shape and petal color, but share the same chromosome number.
Researchers from University Hospital Frankfurt and Goethe University Frankfurt have unraveled how bacteria adhere to host cells and thus taken the first step towards developing a new class of antibiotics.
University of California, Irvine-led researchers have discovered that a signaling molecule called SCUBE3 potently stimulates hair growth and may offer a therapeutic treatment for androgenetic alopecia, a common form of hair loss in both women and men.
The phrase "nuclear energy" conjures images of large steaming towers or Tony Stark's arc reactor from the iconic "Iron Man" movies. But two Seattle-based startups are designing nuclear technologies small enough to pick up and carry that, thanks in part to buy-in from the Defense Department, they hope will fuel a new generation of spaceships.
New genetic research from remote islands in the Pacific offers fresh insights into the ancestry and culture of the world's earliest seafarers, including family structure, social customs, and the ancestral populations of the people living there today.
Researchers at New York University have created artificial Hox genes—which plan and direct where cells go to develop tissues or organs—using new synthetic DNA technology and genomic engineering in stem cells.
A gardener in Pasco County recently found a giant African land snail—or what Florida officials call "one of the most damaging snails in the world."
Researchers have developed a way to create a 3D image of a leaked gas cloud that provides detailed information about the leak such as location, volume and concentration. The new automated detection approach could be used to provide early warnings, assess risk or determine the best way to fix the leak.
Flooding in urban areas cost Americans more than $106 billion between 1960 and 2016, damaging property, disrupting businesses and claiming lives in the process. Determining which areas are most likely to flood amid ever-changing land use and shifting rainfall and climate patterns can be expensive and complicated—and past methods of drawing flood maps fail to capture the inherent uncertainty in...
Scientists from the University of Exeter and the British Geological Survey (BGS), alongside a team of institutions across Europe, have developed a new 3D geological model designed to guide exploration for rare earth elements (REE), which are critical for development of renewable energy and transport.
Bioaerosols, or airborne biological particles containing viruses, fungal spores, bacteria, and pollen, play a key role in public health. Antibiotic resistance (AR), caused by antibiotic resistance genes (ARGs), could potentially cause global public health crises owing to horizontal gene transfer between same or similar bacterial bioaerosols. AR in microbes in soil and water environments have been...
The early 1900s were an exciting time across the world, with rapid advances in the steel, electric and automobile industries. The industrial changes also mark an inflection point in our climate. According to an international team of researchers led by the University of South Florida (USF), the sea level has risen 18 centimeters since the start of the 20th century.
New research has found for the first time that theater productions can help to promote healthier body image in young children.
New research led by Western Sydney University has found that perceptions of major and minor chords and melodies—what Western culture commonly thinks of as "happy music" and "sad music"—may not be universal and is likely the result of culture-dependent familiarity and associative conditioning.
Governments must adopt strong, enforceable treaties to protect oceans affected by global warming, overfishing and rampant pollution, Greenpeace activists said while staging a protest Thursday at the UN Ocean Conference in Lisbon.
Kazakhstan is considering culls of its endangered saiga antelope, the ecology ministry told AFP Thursday, after citing scientific advice about the threat posed to agriculture since the population rebounded.
