Unlike Star Wars projection, 3D technology whips polystyrene bead round at high speedIt may not rival the technology found in a galaxy far, far away, but everyone has to start somewhere. Researchers in Southampton have built a device that displays 3D animated objects that can talk and interact with onlookers.A demonstration of the display showed a butterfly flapping its wings, a countdown spelled...
Could the profound mysteries of antimatter and dark matter be linked? Thinking that they might be, scientists from the international BASE collaboration, led by Stefan Ulmer of the RIKEN Cluster for Pioneering Research, and collaborators have performed the first laboratory experiments to determine whether a slightly different way in which matter and antimatter interact with dark matter might be a...
By using ancient protein sequencing, researchers have retrieved genetic information from a 1.9 million year old extinct, giant primate that used to live in a subtropical area in southern China. The genetic information allows the researchers to uncover the evolutionary position of Gigantopithecus blacki, a three-meter tall and possibly 600 kg primate, revealing the orangutan as its closest living...
Aa team of scientists, led by Harvard researchers, has used a new method of DNA "re-barcoding" to track rapid evolution in yeast. The new approach, published in Nature, advances the field of organismic and evolutionary biology and holds promise for real-world results.
Researchers have developed what is, to date, the most efficient means of converting sewage sludge and restaurant grease into natural gas.
A recent article studies chitin-binding proteins from a soilborne fungus (Verticillium nonalfalfae) that causes vascular wilt in plants. This fungus binds a particular protein (VnaChtBP) to chitin in order to abolish the host plant's chitin-triggered burst of reactive oxygen species and shield the fungus from being digested by the plant.
Researchers developed a tool called Geneva (short for Genetic Evasion), which automatically learns to circumvent censorship. Tested in China, India and Kazakhstan, Geneva found dozens of ways to circumvent censorship by exploiting gaps in censors' logic and finding bugs that the researchers say would have been virtually impossible to find manually.
A new study uncovers several risk factors associated with postpartum opioid overdose.
Urban development in the eastern United States results in an increase in flash flooding in nearby streams, but in the arid West, urbanization has just the opposite effect, according to a Penn State researcher, who suggests there may be lessons to be learned from the sharp contrast.
Next time you visit your hairdresser spare a thought for the pigeons.
Next time you visit your hairdresser spare a thought for the pigeons. For a long time scientists thought the fact that pigeons in urban environments often lost their toes was due to some form of infection, or was a reaction to chemical pollutants. The team from the National Museum of Natural History and the University of Lyon recorded the occurrence and extent of toe mutilations from pigeons...
An insoluble complex carbohydrate, chitin makes up fungal walls and plays a significant role in the interaction between fungal pathogens and their plant hosts. Plant cells harbor immune receptors that perceive chitin and work to stop fungal infection. However, fungal plant pathogens then release chitin-binding proteins that perturb the chitin-triggered immunity.
A second Ebola vaccine is to be offered to thousands of people in the Democratic Republic of Congo.
Old books give off a complex mélange of odors, ranging from pleasant (almonds, caramel and chocolate) to nasty (formaldehyde, old clothes and trash). Detecting early signs of paper degradation could help guide preservation efforts, but most techniques destroy the very paper historians want to save. Now, researchers reporting in ACS Sensors have developed an electronic nose that can...
Watching the behaviour and body language of zoo animals could be the key to understanding and improving their welfare, new research suggests. Traditionally, zoos have focused on more straightforward measures such as whether animals are eating, sleeping and breeding.
Three universities and a health care institution are sharing a gift of more than $1 billion that's one of the largest in the history of higher education, they announced Wednesday.
Some gastrointestinal viruses need calcium. They need calcium ions to carry out several essential aspects of viral life, such as entry into host cells, genome replication and building new viruses to invade other cells. The cells invaded by viruses also use calcium. They use it as signals to regulate many of the cells' own processes, but viruses can takeover cellular calcium signaling to satisfy...
Researchers have developed a way to capture moving objects with the unconventional imaging method known as ghost imaging. The new method could make the imaging technique practical for new applications such as biomedical imaging, security checks and video compression and storage.
A lightweight material full of holes is nearly as hard as diamond. The mere dents left by speeding bullets prove it.
The meet-cute is neatly postponed in this entertaining story of two next-door neighbours, both seeing therapists and looking for loveMuch like the process of psychotherapy itself, patience is required for results while watching this modestly entertaining slow-burn Parisian romance from Cédric Klapisch, who pulls off a neat trick by bumping the meet-cute to the end of the film. What happens before...
Even a minor surgery such as a laparoscopic gallbladder removal can prove to be a high-risk and even fatal procedure for frail patients, according to new research.
Research involving several teams has shown that cellular recycling (autophagy) is repressed during the process of cell division, and how repression of autophagy during mitosis utilizes a different master regulator. The findings address a long-standing point of contention in biology.
Engineers print 3D blocks based on theoretical tubulanes and find they're nearly as hard as diamond.
There is a strong association between the number of fracture-associated drugs (FADs) older patients receive and their risk of sustaining a hip fracture, according to a new study.
