How living systems compute solutions to problems

Jan 17 2018 - 00:01
No individual fish or bee or neuron has enough information by itself to solve a complex problem, but together they can accomplish amazing things. In research published in Science Advances, researchers address how this is possible through a study of the emergence of social structure in primate social groups.

Mass. General study reveals how MRSA infection compromises lymphatic function

Jan 17 2018 - 00:01
Massachusetts General Hospital investigators find that MRSA infection impairs the ability of lymphatic vessels to pump lymphatic fluid to lymph nodes in mouse models, which may contribute to the frequent recurrences of MRSA infection experienced by patients.

Double stranded RNA treatment can reduce fertility of adult house fly pests

Jan 17 2018 - 00:01
Double stranded RNA (dsRNA) can effectively reduce house fly fertility, and shows promise as a pest control method, according to a study published Jan. 17, 2018 in the open-access journal PLOS ONE by Neil Sanscrainte from the USDA/ARS Center for Medical, Agricultural, and Veterinary Entomology, US, and colleagues.

Scale-eating fish adopt clever parasitic methods to survive

Jan 17 2018 - 00:01
A small group of fishes -- possibly the world's cleverest carnivorous grazers -- feeds on the scales of other fish in the tropics. A team led by biologists at the University of Washington is trying to understand these scale-feeding fish and how this odd diet influences their body evolution and behavior.

Titan topographic map unearths cookie-cutter holes in moon's surface

Jan 17 2018 - 00:01
Using the now-complete Cassini data set, Cornell University astronomers have created a new global topographic map of Saturn's moon Titan that has opened new windows into understanding its liquid flows and terrain. Two papers, recently published in Geophysical Review Letters, describe the map and discoveries arising from it.

Children's awarded $2.6M to study stem cells for CHD-related neurological complications

Jan 17 2018 - 00:01
The National Institutes of Health (NIH) awarded researchers at Children's National Health System $2.6 million to expand their studies into whether human stem cells could someday treat and even reverse neurological damage in infants born with congenital heart disease (CHD).

DIPG tumor patterns offer new insight on survival

Jan 17 2018 - 00:01
A small subset of patients with tumors that bear mutations in a gene in the basic packaging of DNA (known as histone mutations) may have better outcomes than others, suggests new research from Michigan Medicine's Pediatric Brain Tumor Research Initiative.

Modular gene enhancer promotes leukemia and regulates effectiveness of chemotherapy

Jan 17 2018 - 00:01
Every day, billions of new blood cells are generated in the bone marrow. The gene Myc is known to play an important role in this process, and is also known to play a role in cancer. Scientists from the German Cancer Research Center (DKFZ) and the HI-STEM have now found that just how big a role Myc plays is determined by a distant section of DNA that contains a cluster of gene enhancers.

Secrets of longevity protein revealed in new study

Jan 17 2018 - 00:01
Named after the Greek goddess who spun the thread of life, Klotho proteins play an important role in the regulation of longevity and metabolism. In a recent Yale-led study, researchers revealed the three-dimensional structure of one of these proteins, beta-Klotho, illuminating its intricate mechanism and therapeutic potential.

Midbrain 'start neurons' control whether we walk or run

Jan 17 2018 - 00:01
Strolling around or running to catch the train similarly requires us to move. However, the neuronal mechanisms in the brain that allow us to initiate and control these movements are different, a new study in the Journal Nature from University of Copenhagen and Karolinska Institutet reveals. 'Start neurons' in the midbrain are essential to take the first step to initiate locomotion and control the speed, mice models show.

Chemical evolution: Progenitors of the living world

Jan 17 2018 - 00:01
RNA was probably the first informational molecule. Now chemists from Ludwig-Maximilians-Universitaet (LMU) in Munich have demonstrated that alternation of wet and dry conditions could have sufficed to drive the prebiotic synthesis of the RNA nucleosides found in all domains of life.

New research to help reduce number of algae blooms that form annually

Jan 17 2018 - 00:01
The study shows that sampling headwaters where streams form can identify which landscapes are resilient enough to handle the rigors of farming and which are vulnerable to leaching toxic residue into waterways.
