Mountain chickadee research shows link between natural selection and spatial memory

Chickadees with better learning and memory skills, needed to find numerous food caches, are more likely to survive their first winter, a long-term study of mountain chickadees has found.

New study provides insights into developmental organization of the brain

What makes us human, and where does this mysterious property of "humanness" come from? Humans are genetically similar to chimpanzees and bonobos, yet there exist obvious behavioral and cognitive differences.

New process efficiently reprograms stem cells in one step using measles virus vector

Induced pluripotent stem cells, the workhorse of many regenerative medicine projects, start out as differentiated cells that are reprogrammed to pluripotent stem cells by exposure to a complex set of genetic cocktails.

New method analyzes how single biological cells react to stressful situations

Human beings are not the only ones who suffer from stress - even microorganisms can be affected. Now, researchers from Chalmers University of Technology, Sweden, have devised a new method to study how single biological cells react to stressful situations.

Researchers uncover new mechanism of how Ebola viruses escape immune system

A research team from Tübingen and Göttingen has described in the renowned journal Cell Reports a new mechanism how the Ebola virus escapes the immune system.

New bioengineered device enhances the production of T-cells

Bone marrow transplants, also known as hematopoietic stem cell transplants, are life-saving treatments for aggressive diseases, such as leukemia and multiple myeloma, and infections such as HIV. The procedure entails infusion of blood stem cells from a matched donor into the patient to 'reset' the blood and immune system.

Super-resolution microscopy could help better study single cells

For a better understanding of biological processes, researchers need to be able to ‘see’ the smallest components of individual cells, such as DNA, mRNA and proteins.

New model sheds light on how small cell lung cancer is initiated

Scientists from Weill Cornell Medicine have developed a stem-cell-based model of small cell lung cancer that will help them understand how the disease is initiated and how it progresses.

How blood cells help wounds heal scar-free revealed in new study

New insights on circumventing a key obstacle on the road to anti-scarring treatment have been published by Maksim Plikus, an associate professor in development and cell biology at the UCI School of Biological Sciences and colleagues in Nature Communications.

Collaborative material research could advance self-assembling nanomaterials

Collaboration between material scientists, biologists and chemists could advance the development of self-assembling nanomaterials, called nanoarchitectonics, argues a review in the journal Science and Technology of Advanced Materials.

Metabolic plasticity helps metastatic cancer cells survive hostile environments

When metastatic cancer cells need to avoid a threat, they simply reprogram themselves. Rice University scientists are beginning to get a handle on how they survive hostile environments.

Novel protein sensor allows researchers to observe nicotine's movements in cells

When a person takes a puff on a cigarette, nicotine floods into the brain, latching onto receptors on the surface of neurons and producing feelings of happiness. But nicotine does not simply stay on the surface of cells--the drug actually permeates into neural cells and alters them from the inside out.

Blood cells could hold the key to aging

Blood cells could hold the key to aging, according to new research out of Case Western Reserve University School of Medicine.

New studies add more evidence for 'grandmother hypothesis,' but there are limits

Humans are unusual in that women go through menopause and stop reproducing long before reaching the end of their life expectancy.

Researchers generate transplantable, functional B-1 cells from mice

Functional B-1 cells derived from mouse embryonic stem cells are capable of long-term engraftment and secrete natural antibodies after transplantation in mice, researchers report February 7 in the journal Stem Cell Reports.

Bariatric surgery changes the way our body senses food

How bariatric surgery helps people with obesity and diabetes is related to changes in the way the gut senses food and nutrients after the operation, researchers report February 5 in the journal Cell Reports.

New research on viral biology could lead to efficient vaccines against leishmaniasis

New research from McGill University has found that a virus infecting the Leishmania parasite spreads by exploiting a mechanism used for cell-to-cell communication, a discovery that could pave the way to new vaccines against infections that cause severe disfiguration.

Mutations in folliculin gene affect embryo implantation

New information is unfolding on the genetic controls of an early turning point in pregnancy. As the tiny, dividing cell mass, the blastocyst, travels from the oviduct and lodges in the wall of the uterus, the cells must exit their pre-implantation state and be ready for post-implantation development.

Detecting and mapping of chemicals inside a biological cell

How are chemicals distributed in a cell? Chinese scientists have developed a combined mass spectrometry and biological imaging device that enables direct, label-free detection, and high-resolution mapping of chemicals inside a biological cell.

New discovery can explain resistance of cancer types to fatty acid metabolism inhibition

Fatty acid metabolism is an essential process in tumor growth and proliferation. Despite different attempts to block fatty acid metabolism as a therapeutic strategy to reduce tumor size and growth, the outcome was not always positive.
