Change in the Immune System Can Lead to Success

Aug. 30, 2016 — The sequencing of the Atlantic cod genome in 2011 demonstrated that this species lacks a crucial part of its immune system. In a follow-up study, researchers have investigated a large number of ... read more

Melanoma: Mechanisms of BRAF-Inhibitor Resistance Deciphered

Aug. 29, 2016 — BRAF mutation occurs in between 40% and 50% of metastasising melanomas (skin cancers), boosting tumour growth. Patients with metastasising melanomas and who display BRAF mutation can be treated with ... read more

Probing How CRISPR-Cas9 Works

Aug. 26, 2016 — A new study reveals important new details about the inner workings of the CRISPR-Cas9 machinery in live cells that may have implications for the development of therapeutics that use the powerful gene ... read more

Aug. 26, 2016 — Researchers have identified RNA-based biomarkers that distinguish between normal, aging hematopoietic stem cells and leukemia stem cells associated with secondary acute myeloid leukemia (sAML), a ... read more

Aug. 26, 2016 — A research team has succeeded in developing 'Target-AID', a genome editing technique that does not cleave the DNA. The technique offers, through high-level editing operation, a method to ... read more

Scientists Shed New Light on the Role of Calcium in Learning, Memory

Aug. 26, 2016 — While calcium’s importance for our bones and teeth is well known, its role in neurons—in particular, its effects on processes such as learning and memory—has been less well defined. A new study ... read more

Physicist's DNA Chip Offers Big Possibilities in Cell, Cancer Studies

Aug. 26, 2016 — A physicist has developed a novel technology that not only sheds light on basic cell biology, but also may aid in the development of more effective cancer treatments or early diagnosis of ... read more

Neuroscientists Stand Up for Basic Cell Biology Research

Aug. 25, 2016 — Clinical trials and translational medicine have certainly given people hope and rapid pathways to cures for some of humankind's most troublesome diseases, but now is not the time to overlook the ... read more

Aug. 25, 2016 — Functional human collagen has been impossible to create in the lab. Now, a team of researchers describes what may be the key to growing functional, natural collagen fibers outside of the body: ... read more

Hormone Activation of Genes Takes Teamwork

Aug. 25, 2016 — A high-throughput look at how human cells respond to the stress hormone cortisol has revealed a more complex system than previously thought. The study found that when the cortisol-binding ... read more

Study Shows Protein Complex Essential to Creating Healthy Blood Cells

Aug. 25, 2016 — A group of proteins best known for helping to activate all mammalian genes has been found to play a particularly commanding role in the natural development of specialized stem cells into healthy ... read more

Aug. 25, 2016 — The process of energy generation by mitochondria is closely tied to intracellular calcium regulation by a membrane gateway inside mitochondria known as the mitochondrial Ca2+ uniporter (MCU). How MCU ... read more

New Technique Takes Guesswork out of IVF Embryo Selection

Aug. 25, 2016 — Researchers have successfully trialed a new technique that could aid the process of choosing the "best" embryo for implantation, helping to boost the chances of pregnancy success from the ... read more

A Look at the Molecular Quality Assurance Within Cells

Aug. 25, 2016 — Proteins fulfill vital functions in our body. They transport substances, combat pathogens, and function as catalysts. In order for these processes to function reliably, proteins must adopt a defined ... read more

Coffee Drinking Habits Can Be Written in Our DNA, Study Finds

Aug. 25, 2016 — Researchers have identified a gene that appears to curb coffee consumption. People with a DNA variation in a gene called PDSS2 tend to drink fewer cups of coffee, the study ... read more

Aug. 25, 2016 — Scientists are testing a drug that could boost levels of critical protective protein in brain. In the study, the team conducted tests in a mouse model of Alzheimer's disease by raising the ... read more

Aug. 25, 2016 — New research shows that certain primate stem cells have pluripotency superior to some types derived from mice. The study maps how pluripotency differs among mice, monkeys, and humans, and illustrates ... read more

Diet, Exercise, Both: All Work Equally to Protect Heart Health

Aug. 24, 2016 — For those who need to lose weight, taking off a few pounds by dieting, exercising or both is powerful protection against cardiovascular ... read more

Enigmatic Molecules Maintain Equilibrium Between Fighting Infection, Inflammatory Havoc

Aug. 24, 2016 — Special RNA molecules called long non-coding RNAs are key controllers for maintaining immune health when fighting infection or preventing inflammatory disorders. The discovery offers a potential drug ... read more
