Tardigrades have captured the imagination of scientists for almost 250 years, thanks to their ability to survive extreme environments that would destroy most other living things. One of these skills is the ability to endure being dried out for up to a decade or longer. Scientists report that this knack for survival is due to a unique set of proteins they dubbed tardigrade-specific intrinsically disordered proteins.
World-first research into the sole remaining living insects of an ancient super-family of crickets has revealed vibrating areas on seemingly unspecialized wings which create sound, representing a transitional stage between those of their fossilized ancestors and the adapted form of modern bush-crickets. The findings will help evolutionary biologists and entomologists better understand the acoustic world the now extinct species once lived.
Scientists have created a new technique that simplifies the production of human brain and muscle cells -- allowing millions of functional cells to be generated in just a few days. The results open the door to producing a diversity of new cell types that could not be made before in order to study disease.
A team of astrophysicists studying an enormous and bizarre young planet approximately 300 lights years from Earth has gained a rare glimpse into the final stages of planetary evolution. While astronomers think the vast majority of planets outside our solar system are inside their star system's vast dusty debris disk, this strange planet is far beyond the disk.
A new study suggests it was the power of the eyes and not the limbs that first led our aquatic ancestors to make the leap from water to land. The researchers discovered that eyes nearly tripled in size before -- not after -- the water-to-land transition. Crocodile-like animals saw easy meals on land and then evolved limbs that enabled them to get there, the researchers argue.
A less strenuous form of exercise known as whole-body vibration (WBV) can mimic the muscle and bone health benefits of regular exercise in mice, according to a new study. WBV consists of a person sitting, standing or lying on a machine with a vibrating platform. When the machine vibrates, it transmits energy to the body, and muscles contract and relax multiple times during each second.
Picture a tablet that you can fold into the size of a phone and put away in your pocket, or an artificial skin that can sense your body's movements and vital signs. A new, inexpensive sensor could help make advanced devices like these a reality.
Scientists have developed a new method that can be used to construct custom hybrid structures using DNA and proteins. The method opens new opportunities for fundamental research in cell biology and for applications in biotechnology and medicine.
Astronomers have directly observed a pair of Milky Way-like galaxies seen when the universe was only eight percent of its current age. These progenitors of today's giant spiral galaxies are surrounded by 'super halos' of hydrogen gas that extend many tens-of-thousands of light-years beyond their dusty, star-filled disks.
Researchers face a fundamental challenge as they seek to scale up human tissue regeneration from small lab samples to full-size tissues and organs: how to establish a vascular system that delivers blood deep into the developing tissue. Researchers have now successfully turned to plants, culturing beating human heart cells on spinach leaves that were stripped of plant cells.
A study of the internal sound waves created by starquakes, which make stars ring like a bell, has provided unprecedented insights into conditions in the turbulent gas clouds where stars were born 8 billion years ago.
A research team reports that fully grown Galapagos penguins who have fledged -- or left the nest -- continue to beg their parents for food. And sometimes, probably when the bounty of the sea is plentiful, parents oblige and feed their adult offspring.
A new study reveals some stunning estimates about how much the world's spiders eat annually: between 400 and 800 million tons of insects and other invertebrates. These eight-legged carnivores play an important role to keep countless insect pests in check.
Fish on the South Pacific island of Rarotonga have evolved the ability to survive out of water and leap about on the rocky shoreline because this helps them escape predators in the ocean. The new study is the first to examine the pressures driving fish out of water and shows the ocean is an enemy-filled environment for the little blennies.
The need to communicate with a wider-world coupled with a move away from the cosy, close-knit communities of the 90s has dramatically changed the way British people speak over the last two decades, new research has revealed. A new study looks at the most characteristic words of informal chit-chat in today's Britain.
Studies of wolf spiders found that courtship displays help preserve genetic isolation between closely related species. Another study found that the species Gladicosa bellamyi used multi-modal communication to entice females.
