After 150 years sitting silently in a museum, a strange specimen has now sung its song once more. Scientists have digitally recreated the sound of a long-lost species of insect, not seen since 1869, by creating 3D scans of its wings. The specifics of the tune could help track down living specimens in the wild – if there are any left.Continue ReadingCategory: ScienceTags: Insect, Species, Animals,
In recent years, we've heard about efforts to replace some of the aggregate used in concrete with crumbled used tires. Now, however, scientists have succeeded in producing good quality concrete in which all of the aggregate has been replaced with tire particles.Continue ReadingCategory: Materials, ScienceTags: RMIT University, Concrete, Tires, Recycling
By using advanced screening methods to tune into the communications taking place between individual cells, scientists have produced the first full connectivity map of the human immune system. This new wiring diagram will help researchers better understand the way different disease such as cancer progress, and work towards next-generation treatments that fortify the body's defenses against them.Co
Scientists have demonstrated a new system that can restore crucial molecular and cellular functions in pigs one hour after death. Experiments showed that some tissue damage from loss of oxygen can be reversed, which could widen the organ transplantation pool and may even lead to new treatments for heart attacks.Continue ReadingCategory: Biology, ScienceTags: Organ donation, Blood, Animals, Cells,
“Optical tweezers” – systems that focus light to trap and manipulate individual atoms – could pave the way for powerful quantum devices, but they can be a little cumbersome. Researchers have now developed a simplified, smaller design for optical tweezers that uses a metasurface lens studded with millions of tiny pillars.Continue ReadingCategory: Physics, ScienceTags: Lens, Metamaterials, Metamate
Researchers at the University of California Riverside (UC Riverside) have identified a single protein that seems to control when hair follicles die. Armed with this new information, it might eventually be possible to reverse the process and stimulate hair regrowth.Continue ReadingCategory: Biology, ScienceTags: Hair, Baldness, Cells, UC Riverside, University of California Riverside, Protein
Scientists have discovered a gene, activated by exercise, which is responsible for building muscle strength. The find also opens the possibility of treatments that offer some of the health benefits even without exercise.Continue ReadingCategory: Health & Wellbeing, LifestyleTags: Exercise, Health, Protein, University of Melbourne, Melbourne University, University of Copenhagen, Muscle
Scientists in Spain have uncovered a mechanism behind why some cancer patients don’t respond well to treatments – and more importantly, found a “weak spot” that could be targeted by existing drugs.Continue ReadingCategory: Medical, ScienceTags: Cancer, Tumor, Tumors, Drug, Drugs, Spain

Researchers at Rice University have shown how they can hack the brains of fruit flies to make them remote controlled. The flies performed a specific action within a second of a command being sent to certain neurons in their brain.Continue ReadingCategory: ScienceTags: Neuroscience, Brain, Brain-to-Brain, Brain stimulation, Magnetic field, Fruit Flies, Rice University, DARPA is a social bookmarking place where you can share, find & discuss the best news around on most topics.
