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.

New 'WormJam model' could provide valuable insights into human aging

What can worms tell us about human aging? A lot more than you'd think; as research led by the Babraham Institute but involving researchers from multiple disciplines drawn together from across the world has shown.

Researchers understand cues controlling collective cell migration during development

Collective cell migration, where groups of cells move together with a common purpose, is important for processes ranging from wound healing to tumor metastasis.

Rare stem cell may be the root of all metastatic cancers

Researchers have discovered a rogue stem cell that could be the cause of all metastatic cancers. The breakthrough could affect all future research projects.

Researchers discover first sour taste receptor used by flies to choose between foods

Taste is so familiar a sensation that you might think scientists had long ago sorted out how the sense works. Yet such research is far from settled.

Chloroplast retrograde signaling attenuates elongation response to shade in plants

Plants need sunlight to feed and grow. Without light, the photosynthesis, the reaction by which the plant chloroplasts convert atmospheric CO2 and water into sugars and oxygen, cannot take place.

Study: BldC protein in Streptomyces acts as ‘brake’ to control timing of sporulation

Streptomyces are soil-dwelling bacteria that produce approximately two-thirds of the antibiotics in current clinical use.

HIV-1 protein plays broader role in suppressing immune response than thought

Scientists have revealed how a protein produced by HIV-1 plays a broader role in suppressing the immune system's response to infection than previously thought.

Researchers describe first case of patient affected by dysfunctions in SLC28 gene family

A research team has described the first case of a patient affected by dysfunctions in a nucleoside transporter of the SLC28 gene family, which brings a set of genes which were not related to human pathologies in the scientific bibliography so far.

Brain stores detailed information of missing hand decades after amputation, finds study

Researchers have found that the brain stores detailed information of a missing hand decades after amputation, regardless of whether amputees still experience phantom hand sensations.
