The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.
Researchers have opened a new front in the battle against aging and diseases associated with old age through a ground-breaking study
By combining multiple advanced technologies into a single system, EPFL researchers have made a significant step forward in diagnosing neurodegenerative diseases (NDDs) such as Parkinson's disease (PD) and Alzheimer's disease (AD).
Prosthetics moved by thoughts. Targeted treatments for aggressive brain cancer. Soldiers with enhanced vision or bionic ears.
The unborn baby “remote controls” its mother’s metabolism, resulting in a nutritional tug-of-war between the two. The mother’s body requires the baby to survive, but she also needs enough glucose and fats in her system to be able to deliver the baby, breastfeed, and reproduce again.
The body's blood glucose level needs to be maintained in a relatively narrow range. It cannot be too high, as it can lead to diabetes, and it cannot be too low because it can cause fainting or even death.
Honey bees have to balance effort, risk and reward, making rapid and accurate assessments of which flowers are mostly likely to offer food for their hive.
A new research paper was published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 15, Issue 12, entitled, "A novel peptide 'T14' reflects age and photo-aging in human skin."
A cochlear signal, the precise role of which has been uncertain since its discovery around 70 years ago, probably gives the brain information on whether the ear is working normally or not.
Taste receptors for bitter substances are not only observed on the tongue but also on cells outside of the oral cavity.
Research of over 22,000 patients with multiple sclerosis (MS) has for the first time discovered a genetic variant linked with speedier progression of the disease, a buildup of disability that can deprive patients of their mobility and independence over time.
Feng Zhang of the Broad Institute at MIT and Harvard and the McGovern Institute for Brain Research at MIT headed a team of researchers who discovered the first programmable RNA-guided mechanism in eukaryotes, which include fungi, plants, and animals.
When octopuses sleep, their quiet periods of slumber are punctuated by short bursts of frenzied activity. Their arms and eyes twitch, their breathing rate quickens, and their skin flashes with vibrant colors.
Glioblastoma (GBM) is the most aggressive and lethal form of brain tumor. Despite treatment, GBM recurrence is inevitable and tends to occur outside surgical margins or in locations remote to the primary tumor, highlighting the central role played by tumor infiltration in this malicious disease.
A study of more than 22,000 people with multiple sclerosis has discovered the first genetic variant associated with faster disease progression, which can rob patients of their mobility and independence over time.
A group from Nagoya University in Japan has discovered that when the diet of nematodes, tiny worms measuring about a millimeter or less in length, includes the bacteria Lactobacillus reuteri, the weakening of associative learning ability caused by aging does not occur.
An improved method of subtyping Alzheimer’s disease based on genetic and tau PET imaging data has been developed computationally.
The brain and the digestive tract are in constant communication, relaying signals that help to control feeding and other behaviors.
A team of researchers at the Marine Biological Laboratory (MBL) has successfully engineered an albino strain of Euprymna berryi, the hummingbird bobtail squid.
Anything with three hearts, blue blood and skin that can change colors like a display in Times Square is likely to turn heads.
Alternative splicing, a clever way a cell generates many different variations of messenger RNAs -; single-stranded RNAs involved in protein synthesis -; and proteins from the same stretch of DNA, plays an important role in molecular biology.
