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 →

Women’s brains appear three years younger than men’s

Time wears differently on women's and men's brains. While the brain tends to shrink with age, men's diminish faster than women's. The brain's metabolism slows as people grow older, and this, too, may differ between men and women. A new... Continue Reading →

Sick And Tired? Scientists Find Protein That Puts Flies To Sleep And Fights Infection

It's cold outside, you're sick and all you want to do is curl up under the covers until you feel better. In fact, the need for sleep can be so strong when we're sick that this may be all we... Continue Reading →

Water Anole

Meet the water anole, a small lizard native to the tropics of Central America. While studying these anoles, researchers discovered that they could flee underwater and remain submerged for 16 minutes or more at a time. Curious to see how the lizard... Continue Reading →

The neurons that rewrite traumatic memories

Memories of traumatic experiences can lead to mental health issues such as post-traumatic stress disorder (PTSD), which can destroy a person’s life. It is currently estimated that almost a third of all people will suffer from fear- or stress-related disorders... Continue Reading →

How the cell eats itself

Autophagy—the process by which a cell digests and recycles various molecules and organelles in its cytoplasm—is critical for maintaining homeostasis and for helping cells survive low-nutrient conditions. In a series of steps, a vesicle precursor, known as the phagophore, is... Continue Reading →
