When a cell divides, it passes through a sequence of complex events and mitochondria, the organelles called the power plants of the cell, are the main source of energy for these processes: They convert food into energy the cell can use.

Freiburg biochemists Dr. Angelika Harbauer and professor Chris Meisinger led a team that have discovered a signaling path that links these two key tasks, cell division and energy conversion. .

8 percent of our genome derives from retroviruses that inserted themselves into human sex cells millions of years ago and right now the koala retrovirus (KoRV) is invading koala genomes.

Koalas are the only known organism where a retrovirus is transitioning from exogenous to endogenous. An exogenous retrovirus infects a host, inserts its genetic information into the cell’s DNA, and uses the host cell’s machinery to manufacture more viruses. When an exogenous retrovirus infects an egg or sperm cell and the viral genetic information is then passed down to the host’s offspring, the virus becomes an endogenous retrovirus (ERV). 

Patients with Amyotrophic lateral sclerosis (ALS), commonly known as Lou Gehrig's Disease, have difficulty with action verbs: Why action verbs and not regular verbs or nouns? 

According to some papers, the fact that ALS patients experience it isn't the actual severe motor deficits of the disease, the greater linguistic difficulty with verbs denoting action compared to nouns depends on the motor deficit.

The motor system plays a role in the semantic encoding of action verbs? Real or spurious correlations? A new tested this hypothesis and their conclusion suggests a major role for the “executive function”.

In the NFL, teams share revenue from national television contracts and to sell local tickets, if a team has not sold at least to a specific threshold, the game is blacked out locally. If enough people are attending, the game is shown to fans in the region

That appeals to 'hometown' fans. One satellite network shows all games to its package subscribers but otherwise fans are only going to see their local team. If they don't have one, they see something nearby. It is a rule and there is no choice.

In the modern mobile population, that may not be a wise strategy. Fans no longer live within an hour of where they grew up and a new paper finds that choosing to broadcast the local team isn't always the smartest ratings decision. Writing in 

Over a mile beneath the West African ocean, off the coast of Angola, are over 2,000 mounds of asphalt containing a wealth of deep-water creatures.

A paper in Deep-Sea Research 1 examined the images and data captured at the site to build an intriguing picture of the life and geology of this underwater area. The naturally-occurring asphalt mounds are made up of the same substance that covers our roads. They range in size from single football-sized blobs to small hills several hundred meters across.

What is the best way to learn a dance sequence?

Professional dancers make it look easy. A choreographer rattles off a long list of moves, kicks and turns and the dancers somehow remember it all. But what about the rest of us who will be hitting the club this weekend?

Researchers from Bielefeld University and the Palucca University of Dance in Dresden are here to help. They  researched whether dancers learn a dance sequence better by seeing or by listening, that is, if a dance instructor first demonstrates the sequence, or if he or she first gives a spoken explanation.
