Scientists have reported that an experimental vaccine targeting one of the most common genetic drivers of pancreatic cancer, called mutant KRAS, is safe and generated a durable immune responses aimed at preventing the cancer.
When it comes to disparities in gender among various, there are no limits to the hypotheses laid out to explain differences, usually in sync with the cultural agenda of the proponent. Engineering, for example, pays women more equally than any field in America but has far fewer women than environmentalist groups, which pay women about $.70 compared to men - yet engineering is criticized for having fewer women. Medical doctors have equal representation while the social sciences have fewer men and the hard sciences have fewer women.
Trisomy 21, commonly called Down syndrome, is a genetic condition in which a person has 47 chromosomes instead of the usual 46 - three of the #21 chromosomes, rather than the usual two.(1)
Down syndrome is one of the most common genetic birth defects, affecting approximately one in 800 to 1,000 babies, and includes a combination of mental retardation, characteristic facial features and, often, heart defects, visual and hearing impairment, and other health problems.
It is very often accompanied by pathologies found in the general population: Alzheimer's disease, leukemia, or cardiac deficiency.
A group of investigators from San Diego State University's Brain Development Imaging Laboratory say they can see the effects of autism on the brain. They conclude that connectivity between the thalamus, a deep brain structure crucial for sensory and motor functions, and the cerebral cortex, the brain's outer layer, is impaired in children with autism spectrum disorders (ASD).
The largest investigation to-date has found a dramatic increase in the number of hospitalizations for children with inflammatory bowel disease (IBD) during the past decade in the United States. But does that mean there are actually more cases?
A National Renewable Energy Lab researcher at the IEEE Photovoltaic Specialists Conference in Tampa announced a 31.1% conversion efficiency for a two-junction solar cell under one sun of illumination.
A new paper published in
Psychonomic Bulletin and Review and based on a small experiment found that people who are blindfolded employ the same strategy to intercept a running ball carrier as people who can see, which suggests that multiple areas of the brain cooperate to accomplish the task. Or they do what they learned when they could see.
Either way, chasing down a moving object is not only a matter of sight or of sound, but of mind.
Attention, activist groups: Open-minded people don't change their view when you control what they learn and they only get one side of the issue, according to a new paper, so framing can only take you so far.
The results of a new paper in the Journal of Communication suggest that climate change deniers may be less effective in swaying public opinion than many scientists and advocates fear, and may even hurt their own cause among those who are most open-minded, according to the authors.
Dopamine, the neurotransmitter celebrity chemical du jour in brain stories, gets invoked a lot because it can make a lot of correlations possible - and that means fun for journalists who either want to highlight the ridiculous or scare you.
Like guns? Dopamine. Are you a Democrat? Dopamine. But aside from its 'pleasure chemical' designation, dopamine has lots of roles in the brain. So if a man takes antipsychotic medication, he may lactate as a side effect, because those medications focus on dopamine. And if there is an addiction story, dopamine is invoked.
A promising anti-cancer therapy - suppression of the protein mammalian target Of Rapamycin (mTOR) - has failed to achieve hoped-for success in killing tumor cells.
mTOR plays an important role in regulating how cells process molecular signals from their environment, and it is observed as strongly activated in many solid cancers. Drug-induced suppression of mTOR has until now shown success in causing the death of cancer cells in the outer layers of cancerous tumors, but has been disappointing in clinical trials in dealing with the core of those tumors.
Interacting with a therapeutic robot companion made people with mid- to late-stage dementia less anxious and also had a positive influence on their quality of life, according to a pilot studyPARO, a robotic harp seal, was used to investigate the effect of interacting with an artificial companion compared with participation in a reading group. PARO is fitted with artificial intelligence software and tactile sensors that allow it to respond to touch and sound. It can show emotions such as surprise, happiness and anger, can learn its own name and learns to respond to words that its owner uses frequently.
How lifeless materials became organic molecules that are the bricks of animals and plants is a science question for the ages.
The world's first known odd couple: 250 million years ago, a mammal forerunner and an amphibian shared a burrow in South Africa.
Scientists scanning a 250 million-year-old fossilized burrow from the Karoo Basin of South Africa have discovered that two unrelated vertebrate animals nestled together and were fossilized after being trapped by a flash flood event. Facing harsh climatic conditions subsequent to the Permo-Triassic (P-T) mass extinction, the amphibian Broomistega and the mammal forerunner Thrinaxodon cohabited in a burrow.
