Vaccines work their magic by effectively creating immune cells that are long lived, often for over decades. These immune cells create both a protective barrier that can prevent or minimize re-infection and a memory that allows us to recognize an old invader like a virus and to kill it before it causes disease. The antibody in our blood that is the barrier is made by 'long lived plasma cells' and...
A new study sheds light on the basic biology of frontotemporal dementia caused by a particular genetic mutation.
People with extended visuomotor experience with inverted movements -- such as vertical dancers -- can overcome the inversion effect in perceiving biological motion.
Researchers have published findings that illustrate how a new device measures hemoglobin more accurately in individuals with darker skin pigmentations.
A study shows that as patients age, Huntington's disease impairs autophagy, which eliminates waste from cells. This housekeeping is significant in Huntington's because a buildup of waste in a specific kind of neuron leads to such cells' untimely deaths. The researchers also showed that enhancing the autophagy pathway in such neurons that were created from skin cells of Huntington's patients...
In animal models, researchers found that intensive physical therapy in tandem with implanted neural stem cells increased tissue growth, repair and functionality in spinal cord injuries more than those treatments alone.
Findings suggest exclusions to Medicaid because of immigration status may increase risk for maternal health care disparities in some immigrant populations.
The parasite Toxoplasma is carried by a large portion of the global human population. Now a study shows how this microscopic parasite so successfully spreads in the body, for example to the brain. The parasite infects immune cells and hijacks their identity.
A collaborative study documents the periodic disappearance (and reappearance) of white-lipped peccaries in nine countries in South and Central America.
More companies must make and implement zero-deforestation supply chain commitments in order to significantly reduce deforestation and protect diverse ecosystems, say researchers.
A study bu a conservation psychologist reveals overwhelming public ignorance of Australia's most threatened species, a factor that is contributing to the extinction crisis of endangered animals.
Scientists investigating why people who have had shingles are at a higher risk of stroke, now believe the answer lies within lipid vesicles called exosomes that shuttle proteins and genetic information between cells, according to new research.
Animals such as spiders make fibers which are strong and elastic. These fibers have a polypeptide structure and serve as inspiration for research into the development of functional materials. Alpha-amino acid N-Carboxyanhydrides (NCAs) are precursors for artificial polypeptides, however they are difficult to produce. Using the photo-on-demand method that they previously developed, a research group...
The largest ever randomized controlled trial of intensive blood pressure lowering after blood clot removal in stroke patients found it led to deterioration in surrounding brain tissue and higher rates of disability, compared to less intensive treatment.
Scientists analyzing the effects of an organic compound on drug resistance bacteria have discovered how it can inhibit and kill a germ that causes serious illness or in some cases death.
Scientists conducted a 7-year study on seedling recruitment and mortality in a national park in Chiang Mai, in northern Thailand. During the study period, an extremely strong El Niño event occurred, leading to a stronger and longer drought than normal. Seasonally dry tropical forests (SDTFs), which experience an annual dry season, are considered drought-tolerant. Nevertheless, the study found...
A new study measured particulate emissions from passenger car preheating with an auxiliary heater in sub-zero conditions. The preheating emissions were compared to calculated emissions from driving to determine the driving distance corresponding to the preheating emissions under current emissions standards.
Hybrids of two common North American songbirds, the black-capped and mountain chickadee, are more likely to be found in places where humans have altered the landscape in some way, finds new research. It's the first study to positively correlate hybridization in any species with landscape changes caused by humans, and the first to examine this relationship across an entire species' range --...
The malignant brain tumor type medulloblastoma can become resistant to therapy which can cause relapse. Researchers have discovered a certain protein that makes tumor cells resting and insensitive to radiation treatment. The research group hopes that the results could eventually lead to better treatments for children that have the highest risk to develop relapses.
Researchers have identified that finger-like cellular extensions called filopodia contribute to building a barrier surrounding breast tumors.
Researchers show that reputation plays a key role in determining which rewarding policies people adopt. Using game theory, they explain why individuals learn to use rewards to specifically promote good behavior.
The evolutionary clade and biodiversity of green lizards of the genera Lacerta and Timon -- reptiles common in the Mediterranean basin and surrounding areas of the European continent, North Africa and Asia -- have never been studied in detail from the perspective of historical biogeography. Now researchers present a new scenario for deciphering the potential evolutionary processes that have acted...
Computing power of quantum machines is currently still very low. Increasing it is still proving to be a major challenge. Physicists now present a new architecture for a universal quantum computer that overcomes such limitations and could be the basis of the next generation of quantum computers soon.
New research has unlocked a mystery in the porous microstructures of sea urchin exoskeletons that could lead to the creation of lightweight synthetic ceramics.
