Fossils of a marine animal that lived 500 million years ago, combined with computer simulations, informed the design of a new soft robot.
New research finds that premature lungs become stiffer than adult lungs under stress. This disrupts the function of transporters that are important for removing water from the lungs after birth.
Charles Darwin -- arguably the most influential man of science in history, accumulated a vast personal library throughout his working life. Until now, 85 per cent of its contents were unknown or unpublished. This year, coinciding with Darwin's 215th birthday, The Complete Work of Charles Darwin Online, a scholarly project, has released an online 300-page catalogue detailing Darwin's complete personal library, with 7,400 titles across 13,000 volumes and items including books, pamphlets and journals.
Scientists examined hundreds of birds in museum collections and discovered a suite of feather characteristics that all flying birds have in common. These 'rules' provide clues as to how the dinosaur ancestors of modern birds first evolved the ability to fly, and which dinosaurs were capable of flight.
The secret to making delicious chocolate with less added sugar is oat flour, according to a new study. In a blind taste test, 25% reduced-sugar chocolates made with oat flour were rated equally, and in some cases preferred, to regular chocolate. The findings provide a new option for decreasing chocolate's sugar content while maintaining its texture and flavor.
Metropolitan areas with multiple city centers and dispersed green spaces mitigate extreme heat more effectively than those with one dominant city, an analysis by city planning scholars finds.
Researchers find deforestation accounts for about 10 percent of global human-made mercury emissions. While it cannot be the only solution, they suggest reforestation could increase global mercury uptake by about 5 percent.
A study has demonstrated that the appearance of ageing skin looks noticeably different compared to younger skin, when examined under polarized laser light. The scientists believe that their new finding could pave the way for new, non-invasive light-based techniques to detect diseases, including cancer, in older individuals. This could significantly enhance early-stage treatment options for various skin conditions.
Scientists have discovered that a known practice in information technology can also be applied to chemistry. Researchers found that to enhance the sampling in chemical simulations, all you need to do is stop and restart.
A chemical element so visually striking that it was named for a goddess shows a 'Goldilocks' level of reactivity -- neither too much nor too little -- that makes it a strong candidate as a carbon scrubbing tool.
For decades, hormonal treatment of breast cancer has been going in one direction -- blocking estrogen. Now a global study has discovered there may be another, less toxic way to defeat the most common form of breast cancer.
A medical researcher has identified a genetic cause for the increased risk of low birth weight in babies born following assisted reproductive technologies such as IVF.
Scientists have discovered five dazzling new species of eyelash vipers in the jungles and cloud forests of Colombia and Ecuador.
Engineers have studied how insects navigate, for the purpose of developing energy-efficient robots.
Children's interest in, and competence perceptions of, mathematics are generally quite positive as they begin school, but turn less positive during the first three years. This is shown by a recent study exploring the development of children's motivation for mathematics during the early school years, and how that development is associated with their mathematics competence. The researchers followed nearly three hundred children for three years.
Climate changes usually happens over long periods of time, but during the last glacial period, extreme fluctuations in temperature occurred within just a few years. Researchers have now been able to prove the phenomenon also occurred during the penultimate glacial period.
Growing cartilage tissue in the lab could help patiens with injuries, but it is very hard to make the tissue grow in exactly the right shape. A new approach could solve this problem: Tiny spherical containers are created with a high-resolution 3D printer. These containers are then filled with cells and assembled into the desired shape. The cells from different containers connect, the container itself is degradable and eventually disappears.
In many cancers, such as ovarian cancer, each round of chemotherapy kills the majority of cancer cells, while a small population of them survives through treatment. These cells are typically more resistant for the next cycle of therapy and can thus regrow to a deadly, treatment resistant tumor. Researchers wanted to know how this small population of surviving cells differs from the other more sensitive cells already before the treatment. To enable this cellular time travel, they developed ReSisTrace, a methodology that takes advantage of the similarity of sister cells to trace back pre-existing treatment resistance in cancer.
Using the results of a standard blood test and an online tool, you can find out if you are at increased risk of having a heart attack within six months.
A new collaborative study analyzed fecal samples to shed light on how the fatal disease impacts the gut microbiome in deer, providing a promising tool for disease surveillance.
