Shape, color, and gloss.
Those are an object's three most salient visual features. Currently, 3D printers can reproduce shape and color reasonably well. Gloss, however, remains a challenge. That's because 3D printing hardware isn't designed to deal with the different viscosities of the varnishes that lend surfaces a glossy or matte look.
Practice makes perfect. In the complex world of medicine too, where just a millimetre can make the difference between success and failure. In partnership with the University of Manizales (Colombia), the Universitat Oberta de Catalunya (UOC) is hosting a project to create a low-cost surgery simulator; a much more accessible tool than those currently available and which could be used to train both surgeons who are in the early stages of their career and those who are more experienced.
An international study has found a link between the brain's network connections and grey matter atrophy caused by certain types of epilepsy, a major step forward in our understanding of the disease.
In a study published this week in The Cryosphere, researchers from the National Centre for Atmospheric Science and University of Reading demonstrate how climate change could lead to irreversible sea level rise as temperatures continue to rise and the Greenland ice sheet continues to decline.
The massive ice sheet faces a point of no return, beyond which it will no longer fully regrow, permanently changing sea levels around the world.
Data analysis of a 12-year longitudinal study examining the importance of personality changes during young adulthood indicates personality growth has real-world career benefits. Kevin Hoff, assistant professor of industrial-organizational psychology at the University of Houston, found young people who develop higher levels of conscientiousness and emotional stability during the transition to employment tend to be more successful in some aspects of their early careers. The study findings are published in Psychological Science.
People can continue using mineral-based aerosol sunscreens without fear of exposure to dangerous levels of nanoparticles or other respirable particulates, according to Penn State research published in the journal Aerosol Science and Engineering.
The findings, reported by a research team led by Jeremy Gernand, associate professor of industrial health and safety, are a result of experiments conducted using three aerosol sunscreens commonly found on store shelves.
EAST LANSING, Mich. - Michigan State University (MSU) researchers have discovered that one of the most important reactions in the universe can get a huge and unexpected boost inside exploding stars known as supernovae.
This finding also challenges ideas behind how some of the Earth's heavy elements are made. In particular, it upends a theory explaining the planet's unusually high amounts of some forms, or isotopes, of the elements ruthenium and molybdenum.
Seasons of change can be difficult to navigate emotionally, not only for adults, but also for children. The ongoing COVID-19 pandemic has undoubtedly impacted children's mental health, and as families start planning for the holidays that may look very different this year, it's important to build resilience in kids to prepare them for what's ahead during these winter months.
SAN ANTONIO, Texas, USA - In a new paper, researchers from The University of Texas Health Science Center at San Antonio (UT Health San Antonio) report brain chemistry that may contribute to why drinkers have difficulty paying attention while under the influence.
The work is funded by generous support from the Robert J. Kleberg, Jr. and Helen C. Kleberg Foundation and by grants from the National Institute on Alcohol Abuse and Alcoholism and the National Institute of Mental Health. Findings were published Dec. 2 in Nature Communications.
New research reveals that some primary school-aged children have self-harmed, prompting calls for intervention efforts to start earlier.
Led by researchers at the University of Melbourne and the Murdoch Children's Research Institute (MCRI), the study assessed more than 1200 children living in Melbourne, Australia, each year from age 8-9 years (wave 1) to 11-12 years (wave 4).
According to scientific estimations, humans are exposed to at least 10,000 to 100,000 environmental and exogenous compounds in an individual lifetime, which are mainly absorbed through our dietary. "Our body can effectively detoxify most of these substances, but various molecules as well as co-exposures can impact drug efficacy," says Benedikt Warth, deputy head of the Department of Food Chemistry and Toxicology at the Faculty of Chemistry and coordinator of the newly founded national exposome research infrastructure, EIRENE Austria.
Fragmented knowledge
An 81-year-old midnight snapper caught off the coast of Western Australia has taken the title of the oldest tropical reef fish recorded anywhere in the world.
The octogenarian fish was found at the Rowley Shoals--about 300km west of Broome--and was part of a study that has revised what we know about the longevity of tropical fish.
The research identified 11 individual fish that were more than 60 years old, including a 79-year-old red bass also caught at the Rowley Shoals.
Groundwater reservoirs in Bavaria have warmed considerably over the past few decades. A new study by researchers at Martin Luther University Halle-Wittenberg (MLU) compares temperatures at 35 measuring stations, taken at different depths, with data from the 1990s. Water found at a depth of 20 metres was almost one degree warmer on average than 30 years ago. The findings were published in the journal "Frontiers in Earth Science".
Scientists have broken the rules of enzyme engineering to unlock a new method for creating chemical reactions that could unlock a wide range of new applications - from creating new drugs to food production.
In their paper published today in Nature Catalysis, Professor Francesca Paradisi and Dr. Martina Contente of the University of Nottingham and the University of Bern show a new method to produce chemical molecules more efficiently through a new one step reaction in the enzyme.
