Scientists have used magnetic nanoparticles to directly control physical movements of mice. Using a technique called Magneto-Thermal Stimulation, researchers activate sections of the brain that cause mice to run, rotate or lose control of the extremities.
If the forecast high temperature in your city is 36 degree Celsius (96.8 degree F), but the heat index makes you feel like it’s 42 degrees (107.6 degree F) – blame the humidity. But why does humidity make it feel hotter?
Fentanyl is a synthetic opioid which is 100 times stronger than morphine and 50 times stronger than heroin. Simply touching it can cause a person to overdose. Fentanyl inhibits pain signals in multiple pathways along the brain and spinal cord, and it also causes your brain to make extra dopamine creating sensations of intense euphoria and relaxation.
A herbal compound called dihydromyricetin (DHM) found in the Oriental raisin tree and rattan tea can cure hangovers. Hangovers are caused by ethanol – the alcohol in your drinks. Ethanol is diuretic which means it increases the flow of urine, and causes you to become dehydrated (which one of the main causes of hangover symptoms).
The chemicals known as quaternary ammonium compounds or "quats," which are often used as disinfectants and preservatives in household and personal products such as cleaners, laundry detergent, fabric softener, shampoo and conditioner, and eye drops, can lead to birth defects of the brain and spinal cord.
A new study by a combined team of researchers from the Queensland University of Technology and The University of Queensland (UQ) has found that bacteria from coughs and sneezes can spread up to 4 meters and remain alive in the air for 45 minutes.
A chemical that triggers the release of melanin, a dark pigment in the skin, without the need for sunbathing or a genetic predisposition for tanning has been created. According to researchers, the chemical can induce a tan even in fair individuals with the type of skin that turns lobster pink rather than bronze in the sun due to lack of melanin.
Scientists have created perfect replicas of human faces that were shown to monkeys just from recording the animal’s brain signals. This has solved one of the most intractable problems in neuroscience – "how the brain recognizes faces."
Chronic sleep deprivation can cause the brain to start eating itself, according to study at the Marche Polytechnic University in Italy. Astrocytes are cells in our brain that destroy and digest worn-out cells and debris, but researchers studying the brain of mice have found that these cells go into overdrive when the animals are chronically sleep-deprived, destroying more of the brain's neural connections.
