It's billed as a health booster and healing agent, but it may be the source of cognitive defects and other severe ailments. A new Stanford-led study reveals that turmeric - a commonly used spice throughout South Asia - is sometimes adulterated with a lead-laced chemical compound in Bangladesh, one of the world's predominant turmeric-growing regions.
When exposed to stress and strain, materials can display a wide range of different properties. By using sound waves, scientists have begun to explore fundamental stress behaviors in a crystalline material that could form the basis for quantum information technologies. These technologies involve materials that can encode information in a number of states simultaneously, allowing for more efficient computation.
They've been called the "special forces" of the immune system: invariant natural killer T cells. Although there are relatively few of them in the body, they are more powerful than many other immune cells.
In experiments with mice, UCLA researchers have shown they can harness the power of iNKT cells to attack tumor cells and treat cancer. The new method, described in the journal Cell Stem Cell, suppressed the growth of multiple types of human tumors that had been transplanted into the animals.
Researchers have outlined how fishing and farming policies could be created to protect employment opportunities and the environment after Brexit.
The team of researchers, led by scientists at the University of York, consulted with key figures from the agriculture and fishing industries nationwide to produce a framework for managing land and seas after the UK has left the EU.
WEST LAFAYETTE, Ind. - Something as simple as an electric field could soon make wartime missiles or drinking mugs easier to produce and more resilient for fracture.
Items such as drinking mugs, missile heads, thermal barrier coatings on engine blades, auto parts, electronic and optic components are commonly made with ceramics.
The ceramics are mechanically strong, but tend to fracture suddenly when just slightly strained under a load unless exposed to high temperatures.
The impostor syndrome, a phenomenon that manifests when people feel like frauds even if they are actually capable and well-qualified, affects people both in the workplace and in the classroom. A new study reveals that perceptions of impostorism are quite common and uncovers one of the best -- and worst -- ways to cope with such feelings.
The study, published today in Advanced Theory and Simulations, shows that digital computers cannot reliably reproduce the behaviour of 'chaotic systems' which are widespread. This fundamental limitation could have implications for high performance computation (HPC) and for applications of machine learning to HPC.
DURHAM, N.C.-- Biomedical engineers at Duke University have used a previously unexplored CRISPR technology to accurately regulate and edit genomes in human cells.
With this new approach, the researchers hope to dramatically expand the CRISPR-based tools available to biomedical engineers, opening up a new and diverse frontier of genome engineering technologies.
Diving seabirds watch each other to work out when to dive, new research shows.
Scientists studied European shags and found they were twice as likely to dive after seeing a fellow bird go underwater.
The study is the first to investigate why large groups (known as "rafts") of shags dive together at sea.
University of Exeter scientists filmed the birds off the Isles of Scilly to examine their behaviour.
An international research team has observed in real time how football molecules made of carbon atoms burst in the beam of an X-ray laser. The study shows the temporal course of the bursting process, which takes less than a trillionth of a second, and is important for the analysis of sensitive proteins and other biomolecules, which are also frequently studied using bright X-ray laser flashes.
