Danger avoidance can be genetically encoded for four generations, say biologists

Princeton University researchers have discovered that learned behaviors can be inherited for multiple generations in C. elegans, transmitted from parent to progeny via eggs and sperm cells. The paper detailing this finding, by Rebecca Moore, Rachel Kaletsky and Coleen Murphy, appears... Continue Reading →

Scientists engineer unique ‘glowing’ protein

Biophysicists from the Moscow Institute of Physics and Technology have joined forces with colleagues from France and Germany to create a new fluorescent protein. Besides glowing when irradiated with ultraviolet and blue light, it is exceedingly small and stable under... Continue Reading →

Circadian clocks: Body parts respond to day and night independently from brain, studies show

Can your liver sense when you're staring at a television screen or cellphone late at night? Apparently so, and when such activity is detected, the organ can throw your circadian rhythms out of whack, leaving you more susceptible to health... Continue Reading →

Researchers use gene editing with CRISPR to treat lethal lung diseases before birth

Using CRISPR gene editing, a team from Children's Hospital of Philadelphia (CHOP)and Penn Medicine have thwarted a lethal lung disease in an animal model in which a harmful mutation causes death within hours after birth. This proof-of-concept study, published today in Science Translational Medicine,... Continue Reading →

Broken mitochondria use ‘eat me’ proteins to summon their executioners

When mitochondria become damaged, they avoid causing further problems by signaling cellular proteins to degrade them. In a paper publishing April 11, 2019, in the journal Developmental Cell, scientists in Norway report that they have discovered how the cells trigger this... Continue Reading →

Cancer: Central role of cell ‘skeleton’ discovered

All cells possess a cytoskeleton which allows them to move and maintain their shape. However, scientists recently showed that a part of this cytoskeleton called branched actin is also essential to cell proliferation, this actin transmits information to cells about... Continue Reading →

A soft spot for stem cells helps cornea healing

New research led by scientists at Newcastle University, UK reveals a potential revolutionary way to treat eye injuries and prevent blindness - by softening the tissue hosting the stem cells which then helps repair wounds, inside the body. The team... Continue Reading →

People can survive organ failure, a review explores how

Although organ failure can be fatal, your kidneys, heart, and liver are prepared for this catastrophe. Emerging research supports the finding that two cell populations quickly respond and work together to restore a non-functioning, or failing, organ. First, the surviving... Continue Reading →

Biologists Discover Unknown Powers in Mighty Mitochondria

Of all the organelles to be found inside eukaryotic cells, the DNA-sheltering nuclei might be the best-known, but the mitochondria are surely not far behind. Mitochondria are familiar as bean-shaped structures floating in the cytoplasm, and they are almost inevitably... Continue Reading →
