Diamonds is the strongest naturally occurring material on Earth. It is also renowned for its incomparable properties, such as high stiffness, exceptional thermal conductivity, high chemical resistance, and high optical transparency. Although these remarkable properties of diamond make it highly desirable for many scientific and technological applications, progress has been slow due to its brittleness.
A recent study, affiliated with UNIST has unveiled that brittle diamonds can be bent and stretched elastically when made into ultrafine needles.
Views on human age need to be revisited. The value of adulthood as a period of certainty has declined for many, which means that this period is being delayed. The processes of personality development vary, and adults are preserving signs of infantilism. HSE University experts, Elena Sabelnikova and Natalia Khmeleva, suggest a new way of looking at the phenomenon of infantilism in their paper Infantilism: Theoretical Construct and Operationalization which avoids a 'judgemental'
The shape of DNA can be changed with a range of triggers including copper and oxygen - according to new research from the University of East Anglia.
The structure of DNA is widely accepted to exist as a double helix, but different DNA structures also exist. New research published today points to a range of triggers that can manipulate its shape.
Applications for this discovery include nanotechnology - where DNA is used to make tiny machines, and in DNA-based computing - where computers are built from DNA rather than silicon.
Researchers using powerful supercomputers have found a way to generate microwaves with inexpensive silicon, a breakthrough that could dramatically cut costs and improve devices such as sensors in self-driving vehicles.
"Until now, this was considered impossible," said C.R. Selvakumar, an engineering professor at the University of Waterloo who proposed the concept several years ago.
High-frequency microwaves carry signals in a wide range of devices, including the radar units police use to catch speeders and collision-avoidance systems in cars.
Preschoolers can learn a lot from educational television, but younger toddlers may learn more from interactive digital media (such as video chats and touchscreen mobile apps) than from TV and videos alone, which don't require them to interact. That's the conclusion of a new article that also notes that because specific conditions that lead to learning from media are unclear, not all types of interactive media increase learning and not all children learn to the same degree from these media.
The research group discovered that between the ages of 4 and 7 children are already starting to associate the plant world with the animal world when asked to draw plants. The researchers studied the spontaneous drawings that 162 girls and 166 boys (328 in all) produced during the final years of Pre-primary Education and the first years of Primary Education.
Research shows that the more skills children bring with them to kindergarten - in basic math, reading, even friendship and cooperation - the more likely they will succeed in those same areas in school. Hence, "kindergarten readiness" is the goal of many preschool programs, and a motivator for many parents.
Now it's time to add language to that mix of skills, says a new University of Washington-led study. Not only does a child's use of vocabulary and grammar predict future proficiency with the spoken and written word, but it also affects performance in other subject areas.
Scientists at the University of Kent have made a significant discovery about how the vitamin content of some plants can be improved to make vegetarian and vegan diets more complete.
Vitamin B12 (known as cobalamin) is an essential dietary component but vegetarians are more prone to B12 deficiency as plants neither make nor require this nutrient.
But now a team, led by Professor Martin Warren at the University's School of Biosciences, has proved that common garden cress can indeed take up cobalamin.
Among couples being treated for infertility, depression in the male partner was linked to lower pregnancy chances, while depression in the female partner was not found to influence the rate of live birth, according to a study funded by the National Institutes of Health.
(Millbrook, NY) Ecologists have long known that agricultural and sewage pollution can cause low oxygen conditions and fish kills in rivers. A study published today in Nature Communications reports that hippo waste can have a similar effect in Africa's Mara River, which passes through the world renowned Maasai Mara National Reserve of Kenya, home to more than 4,000 hippos.
Ibuprofen, given instead of antibiotics to women with uncomplicated urinary tract infection, (cystitis), leads to longer duration of symptoms and more serious adverse events related to the spread of the primary infection, according to a new study in PLOS Medicine by Ingvild Vik and colleagues from the University of Oslo, Norway.
New Haven, Conn.-- In a pilot study published in JAMA Internal Medicine, Yale researchers significantly reduced doses of opioid painkillers given to hospital patients. By delivering the opioids with a shot under the skin or with a pill instead of an IV, the research team found they could decrease patient exposure to the medications while also maintaining or improving pain relief, they said.
CORVALLIS, Ore. - Researchers at Oregon State University are challenging the premise that trophy hunting is an acceptable and effective tool for wildlife conservation and community development.
They argue that charging hunters to kill animals and claim body parts should be a last resort rather than a fallback plan.
In a paper published today in Conservation Letters, the researchers label the practice as morally inappropriate and say alternative strategies such as ecotourism should be fully explored and ruled out before trophy hunting is broadly endorsed.
SAN FRANCISCO - May 11, 2018 -- Researchers from Columbia University have developed a new technique for the powerful gene editing tool CRISPR to restore retinal function in mice afflicted by a degenerative retinal disease, retinitis pigmentosa. This is the first time researchers have successfully applied CRISPR technology to a type of inherited disease known as a dominant disorder. This same tool might work in hundreds of diseases, including Huntington's disease, Marfan syndrome, and corneal dystrophies.
Teachers who antagonize their students by belittling them, showing favoritism, or criticizing their contributions can damage their learning potential, a new study warns.
Investigating the influence of teacher 'misbehavior' on student learning, a team of communication experts set up a teaching experiment in which almost 500 undergraduate students watched a video of a lecture.
