Physicists have observed a light-matter phenomenon in nano-optics, which lasts only attoseconds.
Biomarkers could revolutionize the early detection of and therapy for Alzheimer’s disease. However, experts have criticized that the big breakthroughs are slow in coming because of a lack of priorities in research. A roadmap should help to push along advances in this area.
If pregnant women take antiepileptic drugs, the child can develop autistic traits. The administration of folic acid preparations appears to be a suitable means of preventing this serious side-effect, suggest researchers.
Researchers are focused on preventing or shortening the duration of migraine attacks by looking at established drug treatment options and those that could shape future therapies.
Possible long-term consequences from a whiplash trauma can be effectively predicted if the injured persons are subdivided into different risk groups shortly after the car accident.
The dragonfly considered the most primitive in the world lives in Australia and Tasmania, and was believed to be extinct four decades ago. But it is far from being so. A researcher has observed thousands of these insects in one of the few habitats in which it has been detected and it displays sexual behavior that is unique, not only directed towards reproduction.
The relationship between the job satisfaction of a company’s workforce and its financial success is complex, but a new study has determined that satisfied workers can lead to greater success for an organization.
A researcher reports carrying out chemical-biological research on proteasomes, with an effort to chase a new treatment for cancer.
Computer scientists have developed a new method for conducting image and video database searches based on hand-drawn sketches. The user draws a sketch on a tablet or interactive paper, and the system searches for a matching image in the database. The new method is free to access for researchers.
Astronomers show that it is highly likely that the so-called Planet 9 is an exoplanet. This would make it the first exoplanet to be discovered inside our own solar system. The theory is that our sun, in its youth some 4.5 billion years ago, stole Planet 9 from its original star.
About one in eight women will develop invasive breast cancer over the course of her lifetime. Causes can be the use of synthetic sex hormones and other environmental factors, but also gene mutations like in the BRCA1 gene (BReast CAncer). US actress Angelina Jolie who underwent a preventive double mastectomy is the most famous carrier of a "faulty“ BRCA1 gene. On average, women with this mutation have an up to 87% lifetime risk of developing breast cancer. Tumors usually develop early in life. Until now, prophylactic surgery is the only procedure which significantly reduces the breast cancer risk, but which is also often associated with postoperative complications.
Scientists removed the electric organ from a torpedo and chemically stimulated the organ by injecting a solution of the neurotransmitter acetylcholine though a syringe. They were able to achieve more than a minute of continuous current, with a peak voltage of 91 mV and 0.25 mA of current. By increasing the number of syringes, they achieved a peak voltage of 1.5 V and a current of 0.64mA.
Simply telling people that their opinions are based on morality will make them stronger and more resistant to counterarguments, a new study suggests.
Monkeys who could not use their mediodorsal thalamus were less able to respond to changes that required them to adapt their behavior to continue making the right choices to maximize rewards. They also struggled with their decisions when they were presented with a choice of several differently rewarded options.
When mice experience chronic stress, neurons within part of their brain's fear and anxiety center, the amygdala, retract, new research indicates. It also suggests how such changes could be prevented.
Honeybees collect the vast majority of their pollen from plants other than crops, even in areas dominated by corn and soybeans, and that pollen is consistently contaminated with a host of agricultural and urban pesticides throughout the growing season.
A region of the brain that responds to bad experiences has the opposite reaction to expectations of aversive events in people with depression compared to healthy adults, finds a new study.
Researchers using contrast-enhanced MRI have identified leakages in the blood-brain barrier of people with early Alzheimer's disease, according to a new study. The results suggest that increased BBB permeability may represent a key mechanism in the early stages of the disease.
Exercise that puts greater strain on bones, like running, may improve long-term bone health more effectively than non weight-bearing activities like cycling, conclude the authors of a new study measuring the hormones of mountain ultra-marathon runners.
Chemicals commonly found in plastics and fungicides may be weakening children’s teeth by disrupting hormones that stimulate the growth of dental enamel, according to a new study.
