In today's turtles the shell has a key protective function. The animals can withdraw into it and protect themselves against predators. No other group of vertebrates has modified its physique to such an extent to develop an impenetrable protective structure.
What do squid and jellyfish skin have in common with human skin? All three have inspired a team of chemists to create materials that change color or texture in response to variations in their surroundings. These materials could be used for encrypting secret messages, creating anti-glare surfaces, or detecting moisture or damage, they say.
More than a hundred years ago, Ivan Pavlov conducted what would become one of the most famous and influential psychology studies — he conditioned dogs to salivate at the ringing of a bell. Now, scientists are able to see in real time what happens in the brains of live animals during this classic experiment with a new technique. Ultimately, the approach could lead to a greater understanding of how we learn, and develop and break addictions.
They’re two of the biggest mysteries in Parkinson’s disease research—where does the disease start? And how can it be stopped early in the process?
Hay fever may do more than give you a stuffy nose and itchy eyes, seasonal allergies may change the brain, says a study published in the open-access journal Frontiers in Cellular Neuroscience.
Looking different to your parents can provide species with a way to escape evolutionary dead ends, according to new research from Queen Mary University of London (QMUL).
Wistar scientists have identified a novel mechanism that selectively operates in hypoxic tumors to enable tumor cells to thrive and continue to proliferate despite a low oxygen environment. Dario C. Altieri, M.D., Wistar’s President and CEO and lead author of the study, and colleagues showed how the activation of this pathway leads to an unfavorable prognosis for patients with gliomas – a type of brain tumor – and how the pathway could be a valuable therapeutic target in cancer.
The social lives of crickets are similar generation to generation, even though the insects can't learn directly from their mum and dad.
Wistar scientists have identified a marker that distinguishes PMN-MDSCs from neutrophils in the blood of patients with a variety of cancers.
When human and chimp infants are dozing, they sometimes show facial movements that resemble smiles. These facial expressions -- called spontaneous smiles -- are considered the evolutionary origin of real smiles and laughter.
Spiders living together in colonies of tens of thousands can go extinct from sharing food equitably, finds new UBC research.
Galectin-3, a well-known lectin protein that binds with sugars, could have a number of interactions with other sugar-seeking proteins, which may complicate the biological processes that drive cancer growth, neural growth and white blood cell activities.
Researchers have engineered living bone tissue to repair bone loss in the jaw, a structure that is typically difficult to restore. They grafted customized implants into pig jaws that resulted in integration and function of the engineered graft into the recipient’s own tissue.
Advance will make complex gene studies quicker and easier
Scientists at Sanford Burnham Prebys Medical Discovery Institute (SBP) have made a major advance in understanding how the cells of an organism, which all contain the same genetic information, come to be so diverse. A study published today in Molecular Cell shows that a protein called OCT4 narrows down the range of cell types that stem cells can become. The findings could impact efforts to produce specific types of cells for future therapies to treat a broad range of diseases.
Duke Health-led researchers have discovered new information about the signaling mechanism of cells that could one day help guide development of more specific drug therapies.
Robert Legaspi was 9 years old when he was first diagnosed with acute lymphoblastic leukemia (ALL). This year, at age 27, his leukemia returned for the fourth time. This time was different, though — on May 20, 2016, Legaspi became the first patient in San Diego to receive a new type of immunotherapy, known as CAR T-cell therapy, as part of a Phase I/II clinical trial at Moores Cancer Center at UC San Diego Health.
A new study published Aug. 4 in the New England Journal of Medicine indicates that among African American U.S. Army Soldiers, sickle cell trait is not associated with an increase in mortality, but is associated with a modest increase in the risk of exertional rhabdomyolysis.
By probing the differences between two farming communities, an interdisciplinary team of researchers found that substances in the house dust from Amish, but not Hutterite, homes is associated with changes to immune cells that appear to protect children from developing asthma.
Combinations of Food and Drug Administration-approved drugs protect against the loss of cells required for vision in a mouse model of the damage caused by blinding retinal diseases.
