The study of children's interactions with robots was carried out at the Norwegian research fair held in every major city. It is an annual national event where children gain insight into science and what researchers do.
Roger A. Søraaand his research team at the Norwegian University of Science and Technology's (NTNU) Department of Neuromedicine and Movement Science set up three different robots. Søraa studies people's relationship and interaction with robots. Children ages 6-13 participated in the study.
Invading cells' private space - prying into their internal functions, decisions and communications - could be a powerful tool that may help researchers develop new immunotherapy treatment for cancer. As reported today in Cell, a research group at the Weizmann Institute of Science has developed a technology that enables them to see inside tens of thousands of individual cells at once in greater details than ever before. The group, headed by Prof.
A study of five different seafoods has found traces of plastic in every sample tested.
Researchers bought oysters, prawns, squid, crabs and sardines from a market in Australia and analysed them using a newly developed method that identifies and measures five different plastic types simultaneously.
The study - by the University of Exeter and the University of Queensland - found plastic levels of 0.04 milligrams (mg) per gram of tissue in squid, 0.07mg in prawns, 0.1mg in oysters, 0.3mg in crabs and 2.9mg in sardines.
The system that regulates cellular calcium levels duplicated, generating two non-equivalent systems, some one billion years ago before fungi and animals diverged evolutionarily.
The fungal models currently used for the study of mitochondrial calcium regulation are not adequate, as the system they possess is not equivalent to that of animals. Chytrids, a divergent group of fungi, would be the only fungi that possess a system similar to ours.
The study by IRB Barcelona's Comparative Genomics Laboratory has been published in the journal Nature Communications.
A new way to check nanomaterial quality enters the 'wild frontier' industry
Nanomaterial quality matters: not least when it's used in the aerospace, automotive and construction industries
A new way to check the quality of nanomaterials like graphene has emerged from a team at the University of Sussex.
Polymers reinforced with ultra-fine strands of carbon fibers epitomize composite materials that are "light as a feather and strong as steel," earning them versatile applications across several industries. Adding materials called carbon nanotubes can further enhance the composites' functionality. But the chemical processes used for incorporating carbon nanotube end up spreading them unevenly on the composites, limiting the strength and other useful qualities that can be ultimately achieved.
Vaping is linked to a substantially increased risk of COVID-19 among teenagers and young adults, according to a new study led by researchers at the Stanford University School of Medicine.
The study, which will be published online Aug. 11 in the Journal of Adolescent Health, is the first to examine connections between youth vaping and COVID-19 using U.S. population-based data collected during the pandemic.
WASHINGTON, August 11, 2020 -- Scientists used computational fluid dynamics to determine the effect of temperature on root canal cleaning efficiency. Higher temperatures can, to a point, improve cleansing, but this benefit falls off if the temperature gets too high.
Immunotherapy has revolutionized cancer treatment by stimulating the patient's own immune system to attack cancer cells, yielding remarkably quick and complete remission in some cases. But such drugs work for less than a quarter of patients because tumors are notoriously adept at evading immune assault.
While infant mortality rates (IMR) decreased overall from 2007 to 2015 in California, disparities in infant death rates have increased in some groups, including among obese mothers, those who smoke and African American women, according to a new study published in PLOS One.
Millions of American homes could become unsellable - or could be sold at significant losses to their senior-citizen owners - between now and 2040, according to new research from the University of Arizona.
The study predicts that many baby boomers and members of Generation X will struggle to sell their homes as they become empty nesters and singles. The problem is that millions of millennials and members of Generation Z may not be able to afford those homes, or they may not want them, opting for smaller homes in walkable communities instead of distant suburbs, .
According to research led by The University of Texas at Austin, seasonal rainfall is expected to rise significantly in East Africa over the next few decades in response to increased greenhouse gases.
Scientists at Stockholm University have discovered that water can exhibit a similar behavior like a liquid crystal when illuminated with laser light. This effect originates by the alignment of water molecules, which exhibit a mixture of low- and high-density domains that are more or less prone to alignment. The results, reported in Physical Review Letters on the 11th of August 2020, are based on a combination of experimental studies using X-ray lasers and molecular simulations.
The toughest call to make by a cricket umpire is a leg-before-wicket (LBW) decision and new research from QUT reveals the ability to judge correctly changes with the format of the game, with T20 matches the most likely to produce mistakes.
Joshua M. Adie, a PhD candidate in QUT's School of Exercise & Nutrition Sciences, has just published a new paper highlighting research conducted in partnership with Cricket Australia.
All humans start out from a single cell which then divides to eventually form the embryo. Depending on the signals sent by their adjacent cells, these divided cells are then developed or differentiated into specific tissues or organs.
In regenerative medicine, controlling that differentiation in the lab is crucial as stem cells could be differentiated to allow for the growing of organs in vitro and replace damaged adult cells, particularly those with very limited abilities to replicate, such as the brain or heart.
