Complexity of tumors revealed in 3D

Sciencedaily.com 

A new analysis has revealed detailed 3D maps of the internal structures of multiple tumor types. These cancer atlases reveal how different tumor cells -- and the cells of a tumor's surrounding environment -- are organized, in 3D, and how that organization changes when a tumor spreads to other organs. The detailed findings offer scientists valuable blueprints of tumors that could lead to new approaches to therapy and spark a new era in the field of cancer biology, according to the researchers.

Minnesota GOP scores a win challenging who will review absentee ballots in Hennepin County

«SFGate» (sfgate.com) 

The Minnesota Supreme Court says election officials in Hennepin County have to pick new board members to validate absentee ballots. Until now, the board has been made up of one Republican and four Democrats. Now the court has ordered the state's most populous county to go back to a list of eligible election judges submitted by the state’s Republican Party and pick new members. The court said late Tuesday that Hennepin officials had a duty to appoint election judges off the party’s list before letting cities pick from it. Читать дальше...

Healthy brains suppress inappropriate immune responses

Sciencedaily.com 

Researchers have found a process by which the brain guards against attack by the immune system. In mice with multiple sclerosis, such 'guardian' proteins that train the immune system were drastically depleted, and replenishing them improved symptoms, according to a new study.

Large meltwater accumulation revealed inside Greenland Ice Sheet

Sciencedaily.com 

A new study unveils a surprising discovery: a substantial amount of meltwater is temporarily stored within the Greenland Ice Sheet during summer months. For the first time, an international group of researchers was able to quantify meltwater with positioning data. The finding challenges current models of how ice sheets contribute to global sea level rise.

Ancient DNA brings to life history of the iconic aurochs, whose tale is intertwined with climate change and human culture

Sciencedaily.com 

Geneticists have deciphered the prehistory of aurochs -- the animals that were the focus of some of the most iconic early human art -- by analyzing 38 genomes harvested from bones dating across 50 millennia and stretching from Siberia to Britain. The aurochs roamed in Europe, Asia and Africa for hundreds of thousands of years. Adorned as paintings on many a cave wall, their domestication to create cattle gave us a harnessed source of muscle, meat and milk. Such was the influence of this domestication... Читать дальше...

Discovery illuminates how sleeping sickness parasite outsmarts immune response

Sciencedaily.com 

A new study sheds light on how the blood-borne parasite that causes African sleeping sickness in humans and related diseases in cattle and other animals establishes long-term infections in hosts. Using a mouse model, the researchers showed that Trypanosoma brucei essentially plays a game of hide-and-seek by setting up shop in its hosts' tissues, allowing it to constantly change its protective surface coat and evade antibodies.
