New research which "fills in the blanks" on what ancient Papuan New Guineans ate, and how they processed food, has ended decades-long speculation on tool use and food stables in the highlands of New Guinea several thousand years ago.
Findings from the "Joe's Garden" site in the Ivane Valley in the New Guinea highlands end several decades of academic speculation about what a formally manufactured mortar and other tools were used for, and shows a variety of once widely eaten starchy plants were processed in the area.
A team including researchers from the Department of Chemistry at the University of Tokyo has successfully captured video of single molecules in motion at 1,600 frames per second. This is 100 times faster than previous experiments of this nature. They accomplished this by combining a powerful electron microscope with a highly sensitive camera and advanced image processing. This method could aid many areas of nanoscale research.
Durham, NC - In the search for a cure for Alzheimer's disease, mesenchymal stem cells and their derived extracellular vesicles (MSC-EVs) offer much promise, thanks to their protective and anti-inflammatory properties. The results from a new study done on mice, released today in STEM CELLS Translational Medicine, strengthens this idea by showing for the first time that MSC-EVs delivered by way of the nasal passages reduce inflammation - believed to be a prime factor in Alzheimer's disease. They also trigger actions that guard the brain's neurons against further degenerative effects.
Indiscriminate feeding by an alien population of the carnivorous spotted-thighed frog - could severely affect the native biodiversity of southern Australia according to a new study by the University of South Australia.
The invasive amphibian - Litoria cyclorhyncha - which has hitchhiked across the Nullarbor from Western Australia - has now established a community of 1000-plus in Streaky Bay, South Australia, with sightings also confirmed on the Eyre Peninsula and at the Adelaide airport.
Washington State University researchers have developed a technology that is more than 30 times more sensitive than current lab-based tests in finding early stage cancer biomarkers in blood.
The technology uses an electric field to concentrate and separate cancer biomarkers onto a paper strip. It could someday become a kind of liquid biopsy and could lead to earlier detection of and faster treatments for cancer, a disease that causes more than 9.6 million deaths a year around the world.
A technique that has greater sensitivity to assess harmful chemicals adds to the analysis toolkit for cigarette alternatives. This research by KAUST scientists, now published in Tobacco Control, reveals that a tobacco-heating device called "I quit ordinary smoking" (IQOS), emits many more potentially harmful chemicals than those identified by the manufacturer.
Parents with temperamental children should pay special attention to helping them develop good eating habits. These children are more susceptible to developing an unhappy relationship with food, researchers from the Norwegian University of Science and Technology (NTNU) have found.
Temperament is often equated with anger, but it embraces much more. Temperament is the child's fundamental way of dealing with his environment and himself. It can be regarded as a precursor to what is called personality in adults.
UC Santa Barbara researchers continue to push the boundaries of LED design a little further with a new method that could pave the way toward more efficient and versatile LED display and lighting technology.
In a paper published in Nature Photonics, UCSB electrical and computer engineering professor Jonathan Schuller and collaborators describe this new approach, which could allow a wide variety of LED devices -- from virtual reality headsets to automotive lighting -- to become more sophisticated and sleeker at the same time.
Electricity storage in batteries is in ever increasing demand for smartphones, laptops, cars and the power grid. Solid-state batteries are among the most promising next-generation technologies because they offer a higher level of safety and potentially longer life.
Researchers at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) have discovered a system that provides cells with information about their position within developing organs. This system, studied in developing limbs, tells cells what anatomical structure they need to form within the organ. The article, published today in Science Advances, shows that malfunctioning of this system causes congenital malformations and could in part explain the effect of thalidomide, a drug contraindicated in pregnancy because it induces limb defects.
A new scoring approach introduced in 2009 to curb bias during the National Institutes of Health (NIH) Enhanced Peer Review process did not mitigate the gap in preliminary overall impact scores between black and white principal investigators (PIs) for the years 2014 to 2016, a new study shows. Black investigators, on average, received worse preliminary scores for all five criteria - Significance, Investigator(s), Innovation, Approach, and Environment - even after accounting for career stage, gender, type of degree, and scientific field.
ITHACA, N.Y. - Essential processes in mammalian cells are controlled by proteins called transcription factors. For example, the transcription factor HIF-1 is triggered by a low-oxygen situation to cause the cell to adapt to decreased oxygen.
Transcription factors operate in healthy cells, but cancer cells can co-opt transcription factors such as HIF-1 into promoting tumor growth.
The third tropical cyclone of the Atlantic Ocean basin has been generating large amounts of rainfall over Mexico's Yucatan and parts of Central America. Using satellite data, NASA analyzed that heavy rainfall and provided forecasters with valuable cloud top temperature data to help assess the strength of the storm.
On June 2, 2020, by 2 p.m. EDT, Tropical Depression 03L strengthened into Tropical Storm Cristobal over Mexico's Gulf of Campeche. The Gulf of Campeche is surrounded by Mexico's Yucatan Peninsula, and the gulf is part of the southwestern Gulf of Mexico.
A team of researchers based in Manchester, the Netherlands, Singapore, Spain, Switzerland and the USA has published a new review on a field of computer device development known as spintronics, which could see graphene used as building block for next-generation electronics.
Recent theoretical and experimental advances and phenomena in studies of electronic spin transport in graphene and related two-dimensional (2D) materials have emerged as a fascinating area of research and development.
When Wei Hsi (Ariel) Yeh was a young undergraduate student, one of her close friends went from normal hearing to complete deafness in the span of one month. He was 29 years old. No one knew why he lost his hearing; doctors still don't know. Frustrated and fearful for her friend, Yeh, who graduated last month with her Ph.D. in chemistry from Harvard University, dedicated her graduate studies to solving some of the vast genetic mysteries behind hearing loss.
