Study Supports Use of Age-Specific Risk Prediction Scores for Dementia

Washington, 19 May (ONA) --- Vascular risk factors which are associated with the risk of developing dementia may vary with age. A new study shows that among people around age 55, the risk of developing dementia over the next 10 years was increased in those with diabetes and high blood pressure.For people around 65 years old, the risk was higher in those with heart disease, and for those in their 70s, diabetes and stroke. For 80-year-olds, the risk of developing dementia was increased in those with diabetes and a history of stroke, while taking blood pressure medications decreased the ...

Textbooks Need More Real-World Math Exercises, Study Finds

Washington, 17 May (ONA) --- A typical 8th grade math textbook includes just a handful of real-world problems for students to solve, finds a new international study.And that’s not enough, according to William Schmidt, distinguished professor at Michigan State University. “It’s not enough anymore to just teach the kids the fundamental skills, but to move toward being able to reason with those to solve real-world examples,” he said, “because the textbooks simply do not provide enough opportunities for students to actually practice applying mathematics in real-world ...

Nasa Rover Begins Key Drive to Find Life On Mars

Washington, 17 May (ONA) --- Nasa’s Perseverance rover, the six-wheeled robot, today will see a big moment in its mission on Mars as it will start to climb up an ancient delta feature in the crater where it landed.It will roll uphill, stopping every so often to examine rocks that look to have the best chance of retaining evidence of past life on the planet.On its way back down, Perseverance will collect some of these rocks, placing the samples at the base of the delta to be retrieved by later missions.The goal is to bring this material back to Earth in the 2030s for detailed ...

Tonga Eruption Was Record Atmospheric Explosion

Washington, 15 May (ONA) --- The eruption of the Tonga volcano in January has been confirmed as the biggest explosion ever recorded in the atmosphere by modern instrumentation. It was far bigger than any 20th Century volcanic event, or indeed any atom bomb test conducted after WWII. The assessment comes in a pair of scholarly papers in the journal Science that have reviewed all the data. Of recent history, it's likely only the Krakatoa eruption of 1883 rivalled the atmospheric disturbance produced. That catastrophic event in Indonesia is thought to have claimed more than ...

Time Off Social Media Boosts Mental Health: Study

London, 15 May (ONA) --- It’s no secret that too much social media can be bad for one’s mental health. Now, research suggests that taking even a brief break from social media platforms can ease symptoms of depression and anxiety.Staying off social media for a week meant, for some study participants, gaining about nine hours of free time, which improved their well-being, British researchers report.“If you’re feeling like you use too much social media and this is negatively impacting your mental health, then taking a break may be worth a try and give you at least some ...

Astronomers Capture 1st Image of Milky Way’s Huge Black Hole

Washington, 12 May (ONA) —- The world got a look today at the first wild but fuzzy image of the supermassive black hole at the center of our own Milky Way galaxy, with astronomers calling it a “gentle giant” on a near-starvation diet.Astronomers believe nearly all galaxies, including our own, have these giant black holes at their center, where light and matter cannot escape, making it extremely hard to get images of them. Light gets chaotically bent and twisted around by gravity as it gets sucked into the abyss along with superheated gas and dust.The colorized image unveiled today is ...

Astronomers Discover Trails of More Than 1,000 Possible Asteroids

"One astronomer’s trash can be another ...

Climate Change May Increase Risk of New Infectious Diseases

London, 28 Apr (ONA) --- Climate change will result in thousands of new viruses spread among animal species by 2070 — and that’s likely to increase the risk of emerging infectious diseases jumping from animals to humans, according to a new study. Researchers, who published their findings today in the journal Nature, used a model to examine how over 3,000 mammal species might migrate and share viruses over the next 50 years if the world warms by 2 degrees Celsius (3.6 degrees Fahrenheit), which recent research shows is possible. They found that cross-species virus spread will ...

Recycling Vital for Green Metal Needs: Study

London, 25 Apr (ONA) --- Recycling could plug the gap from 2040 to the European Union’s (EU) needs of lithium, rare earths and other metals needed to cut carbon emissions. The study indicated that the global energy transition is progressing fast and that copper, cobalt, lithium, nickel and rare earths are all at risk of disruptive demand pull between now and 2035. The EU's pledge to cut net greenhouse gas emissions to zero by 2050 will require large amounts of metals and minerals to roll out electric vehicles (EVs) and wind turbines. The study said the bloc will need 35 ...

Newly Found Mechanism Explains How Fine Air Pollution Particles May Cause Lung Cancer

Beijing, 20 Apr (ONA) --- Scientists have identified a mechanism that explains how fine air pollution particles might cause lung cancer, according to a study published today in eLife.The findings could lead to new approaches for preventing or treating the initial lung changes that lead to the disease.Tiny, inhalable fine particulate matter (FPM) found in air pollutants has been recognized as a Group 1 carcinogen and a substantial threat to global health. However, the cancer-causing mechanism of FPM remains unclear."Despite its potential to cause mutations, recent research suggests that ...

People Learn Relevant Information Better During Stressful Event

California, 19 Apr (ONA) --- New findings on the effects of stress on memory suggest that people tend to recall information better when the information is related to the stressful event. However, the factor of delay—that is, the time between a stressful event and learning information—does not appear to have as strong an influence on the relationship between stress and memory as previously thought. "The effects of acute stress on memory encoding are complex," said Grant Shields, lead author of a study published in Learning and Memory. "Our work shows that relevance of ...

Nanoparticles Prove Effective Against Yellow Fever Mosquito

Ohio, 19 Apr (ONA) --- The yellow fever mosquito became an invasive species, but researchers at the Ohio State University in the USA may have found a way to squash the pesky population in its juvenile stages.Recently published in the journal Insects, a new paper describes how mosquitoes have evolved a natural resistance to some chemical insecticides, and offers an alternative called carbon black, a type of carbon-based nanoparticles, or CNPs.Study co-author and an associate professor of entomology at Ohio State, Peter Piermarini described CNPs as “microscopic” materials made out of ...

Scientists Discover Brain Circuit That Boosts Math's Skills in Children

Washington, 12 Apr (ONA) --- Scientists have discovered a brain circuit that boosts math's skills in children and could even be targeted to improve learning.The circuit triggers an area near the back of the head known as the IPS (intraparietal sulcus), which is involved in processing figures, and is linked to the hippocampus where memories are stored.Before children can learn to add and subtract, they must learn which abstract symbol, like '4' or '6', represents which quantity, a skill also known as 'number sense'.Experts know the IPS plays a role in number processing but the ...

Researchers Create 3D-Printed Fingertip That Has Sense of Touch Like Human Skin

London, 6 Apr (ONA) --- Researchers have created a new 3D-printed fingertip that has a sense of touch like human skin and could help improve .While machines might be able to beat the world's best chess player, they lack the ability to pick up a chess piece even as well as a child.This is partly because the artificial grippers on robots do not have the same feel as a human fingertip, and this is used to guide human hands as objects are handled.However, the new fingertip was able to produce artificial nerve signals that looked like those produced by signals from various human nerve ...

Rare Glimpse of Giant Planet, Nine Times the Mass of Jupiter

Washington, 5 Apr (ONA)--- Scientists have observed an enormous planet about nine times the mass of Jupiter at a remarkably early stage of formation – describing it as still in the womb – in a discovery that challenges the current understanding of planetary formation. The researchers used the Subaru telescope, near the summit of an inactive Hawaiian volcano, and the orbiting Hubble space telescope to detect and study the planet called AB Aurigae b, a gas giant orbiting unusually far from its young host star. Gas giants are planets, like our solar system’s largest ones ...
