In the quantum world of light, being distinguishable means staying lonely. Only those photons that are indistinguishable can wind up in a pair, through what is called Hong-Ou-Mandel interference. This subtle quantum effect has been successfully imaged for the first time.
Cloud security reaches silicon: System for defending against memory-access attacks implemented in chips
A system for defending against memory-access attacks can be implemented in chips.
For years, health advocates have been pushing to ban some flame retardants for their potentially harmful effects, especially on young children and infants. Now scientists report these compounds could play a role in a common health problem for one of our most beloved pets: cats. A new study found that cats with hyperthyroidism had high levels of certain flame retardants, hinting at a possible link.
If you've studied ingredient labels on food packaging, you've probably noticed that soy lecithin is in a lot of products, ranging from buttery spreads to chocolate cake. Scientists have now found a potential new role for this all-purpose substance: dispersing crude oil spills. Their study could lead to a less toxic way to clean up these environmental messes.
As baby boomers age, the number of people diagnosed with Parkinson's disease is expected to increase. Patients who develop this disease usually start experiencing symptoms around age 60 or older. Currently, there's no cure, but scientists are reporting a novel approach that reversed Parkinson's-like symptoms in rats. Their results could one day lead to a new therapy for human patients.
Using an ultra bright X-ray source, scientists have decoded the molecular and three-dimensional structure of two promising drug candidates from the new group of Spiegelmers for the first time. The results provide a deeper understanding of the mode of action of these substances that have already entered clinical trials.
Several drugs could lead to new treatment options for multiple sclerosis, including two drugs that effectively treat MS at the source, in vivo, researchers report. At the pathological level, MS is a disease in which the immune system attacks the protective myelin sheath, a type of insulation that covers nerves, ultimately disrupting communication between the brain and the body and leading to nerve deterioration.
In a new study, researchers have made insights into how the blood-brain barrier, or BBB, is maintained, identifying a protein key to the process. Delivering this protein to mice with the rodent equivalent of MS improved their symptoms.
It may seem unlikely that a large earthquake would take place hundreds of kilometers away from a tectonic plate boundary, in areas with low levels of strain on the crust from tectonic motion. But major earthquakes such as New Zealand's 2011 Mw 6.3 quake have shown that large earthquakes do occur. So what should seismologists look for if they want to identify where an earthquake might happen despite the absence of historical seismic activity?
The 'seismic crisis' around the region of the Chiles and Cerro Negro de Mayasquer volcanoes near the Columbia-Ecuador border is likely caused by intruding magma, according to a new report.
The changing British landscape could be contributing to the decline in its bee populations, according research. Analysis of 35 hives in 20 sites in North West England found that honeybees living near areas of extensive farmland were surviving on a lower protein diet than those in hives near natural grasslands and woodlands.
With Caribbean people in the UK nine times more likely than white British counterparts to be diagnosed with schizophrenia, a mental health researcher has visited Jamaica and Barbados to find out what lessons can be learned.
The mechanics of the lower vertebrae have been the focus of recent study. Researchers are aiming to reveal how wear and tear comes about on vertebral bodies and spinal disks, hoping to make easier the choice of appropriate therapy.
Researchers have uncovered the first evidence of a genetic link between prodigy and autism. The scientists found that child prodigies in their sample share some of the same genetic variations with people who have autism.
Brain researchers have developed a new brain mapping model that could improve the success rate of transcranial magnetic stimulation (TMS) in treating conditions including depression, neuropathic pain, and stroke. The model helps pinpoint target sites during TMS, a procedure that uses magnetic fields to stimulate nerve cells in the brain to alleviate or eliminate symptoms of stroke, depression, and attention disorders.
A newly minted Ph.D. surveyed county Extension directors, their subordinates and peers. The student connected diet and exercise to emotional leadership, a key component for leaders everywhere.
Known by a variety of names, “hyping,” “champing” and “freaking” a cigarillo – a smaller, leaner type of cigar – is believed by many to significantly reduce the amount of cancer-causing properties associated with tobacco products. A new study examines such claims.
Researchers have been attempting to understand the cascade of events following mild head injury that may lead to an increased risk for developing a progressive degenerative brain disease, and their new study shows initial promise for a treatment that might interrupt the process that links the two conditions.
Chemists have created a device that generates and detects terahertz waves over a wide spectral range with extreme precision, allowing it to be used as an unparalleled tool for measuring terahertz waves.
Engineers have discovered a method to increase the amount of electric charge that can be stored in graphene, a two-dimensional form of carbon. The research may provide a better understanding of how to improve the energy storage ability of capacitors for potential applications in cars, wind turbines, and solar power.
