Biological Budding yeast cells turn back the clock
Gametogenesis Eliminates Age-Induced Cellular Damage and Resets Life Span in Yeast. Elçin Ünal et al.
 
The process by which rejuvenation occurs in new generations has long interested biologists and vexed fairytale stepmothers....

Biological Fussy about filaments
Actin Network Architecture Can Determine Myosin Motor Activity. Reymann et al.
 
Living organisms’ ability to move around is essential to survival. In living cells, this ability to move is highly dependent on the cytoskeleton, and specifically, the contractive force generated by...

Biological One RING to fool them all: shedding light on BRCA1 mutations
BRCA1 Tumor Suppression Depends on BRCT Phosphoprotein Binding, But Not Its E3 Ligase Activity. Shakya et al.
 
Inherited mutations in the breast cancer susceptibility genes BRCA1 and BRCA2 are associated with a markedly...

Biological Lights, motor neurons, and muscle action!
Optical Control of Muscle Function by Transplantation of Stem Cell–Derived Motor Neurons in Mice. Bryson et al.
 
After nerve injury or neurodegenerative disease, patients suffer paralysis and loss of muscle mass due to limited neuron regeneration. Major obstacles to restoring...

Biological Gearing up to Jump
Interacting Gears Synchronize Propulsive Leg Movements in a Jumping Insect. Malcolm Burrows and Gregory Sutton.
 
Imagine jumping in a mere 2 one-thousands of a second (2 ms). Juvenile planthoppers, jumping insects that eat the sap inside of plants, can do just that. One reason...

Biological Do Birds of a Feather Flock Together?

Ancient DNA Reveals Elephant Birds and Kiwi are Sister Taxa and Clarifies Ratite Bird Evolution.  Mitchell et al.

The species we see on earth today have been shaped by millions of years of evolution. Over great periods of time, species often change and adapt in response to environmental cues and constraints. One of the...

Biological Implanting false memories
Creating a False Memory in the Hippocampus. Ramirez et al.
 
The brain is plastic and processes information from the surroundings by coordinating activities between different regions. Research has shown that the neurons in the hippocampus are involved in the formation of...

Physical Black holes and galaxies...having a blast together
Radio Jets Clearing the Way Through a Galaxy: Watching Feedback in Action. Morganti et al.
 
Supermassive black holes exist at the center of galaxies, often weighing more than one billion times as much as the sun.  What forces could connect the mass of a galaxy to the mass of...

Biological Do you remember being born?
Hippocampal Neurogenesis Regulates Forgetting During Adulthood and Infancy.  Akers et al.
 
Why do we have so much trouble remembering our own infancy? This phenomenon, known as infantile amnesia, occurs in humans as well as many animal species. Does the synthesis of...
