What does a virtual roller coaster ride tell us about migraine?

When experiencing the ups and downs of a virtual roller coaster ride, people who get migraine headaches reported more dizziness and motion sickness than people who do not get migraines, according to a new study.

Advantages of intranasal vaccination against SARS-CoV-2

There are many reasons that an intranasal vaccine against the SARS-CoV-2 virus would be helpful in the fight against COVID-19 infections, immunologists write in a new article.

Neuroscientists posit that brain region is a key locus of learning

Long thought of as a generic alarm system, the locus coeruleus may actually be a sophisticated regulator of learning and behavior, according to a new review.

Americans with higher net worth at midlife tend to live longer

In a wealth and longevity study to incorporate siblings and twin pair data, researchers analyzed the midlife net worth of adults (mean age 46.7 years) and their mortality rates 24 years later. They discovered those with greater wealth at midlife tended to live longer.

Better healthcare management can reduce the risk of delirium among older adults

New research by an Executive PhD Research student at the Business School (formerly Cass) outlines how elderly patients with neurological conditions are significantly more likely to develop delirium shortly after they are hospitalised, and those admitted on Sunday and Tuesday are more likely to develop the disorder.

'Feel good' brain messenger can be willfully controlled, new study reveals

Researchers have discovered that spontaneous impulses of dopamine, the neurological messenger known as the brain's 'feel good' chemical, occur in the brain of mice. The study found that mice can willfully manipulate these random dopamine pulses for reward.

New measure of tropical forest vulnerability to help avoid 'tipping point'

Humid tropical forests, vital in global efforts to limit rising temperatures, are under threat as a result of changes in land use and climate. Now, researchers have developed a new way to keep tabs on the vulnerability of these forests on a global scale using satellite data called the tropical forest vulnerability index (TFVI).

Cascaded metasurfaces for dynamic control of THz wavefronts

Researchers have developed a general framework and metadevices for achieving dynamic control of THz wavefronts. Instead of locally controlling the individual meta-atoms in a THz metasurface (e.g., via PIN diode, varactor, etc.), they vary the polarization of a light beam with rotating multilayer cascaded metasurfaces.

Why four-legged animals are better sprinters

Scientists have studied the characteristics determining the maximum running speed in animals. The model they developed explains why humans cannot keep up with the fastest sprinters in the animal kingdom. Based on these calculations, the giant spider Shelob from 'The Lord of the Rings' would have reached a maximum speed of 60 km/h.

Reverse optogenetic tool developed

A new optogenetic tool, a protein that can be controlled by light, has been characterized by researchers. They used an opsin -- a protein that occurs in the brain and eyes -- from zebrafish and introduced it into the brain of mice. Unlike other optogenetic tools, this opsin is not switched on but rather switched off by light. Experiments also showed...
