Caching System could make Data Centers more Energy Efficient

Researchers from CSAIL have devised a new system for data center caching that uses flash memory. In addition to costing less and consuming less power, a flash caching system could dramatically reduce the number of cache servers required by a data center. Credit: MIT News

Flash-memory system could reduce power consumption of data center ‘caches’ by 90%. Researchers have developed a new system for data center caching that uses flash memory, the kind of memory used in most smartphones. Most modern websites store data in databases, and since database queries are relatively slow, most sites also maintain so-called cache servers, which list the results of common queries for faster access...

1st hints of possible Water content on TRAPPIST-1 Planets

This artist's impression shows the view from the surface of one of the planets in the TRAPPIST-1 system. At least seven planets orbit this ultracool dwarf star 40 light-years from Earth and they are all roughly the same size as the Earth. Several of the planets are at the right distances from their star for liquid water to exist on the surfaces. Credit: ESO/N. Bartmann/spaceengine.org

An international team used Hubble to estimate whether there might be water on the 7 earth-sized planets orbiting the nearby dwarf star TRAPPIST-1. The results suggest that the outer planets of the system might still harbour substantial amounts of water. This includes the 3 planets within the habitable zone of the star, lending further weight to the possibility that they may indeed be habitable.

The team used ...

Scientists Recover Nova 1st Spotted 600 years ago by Korean Astrologers

This image shows the recovered nova of March 11, 1437 and its ejected shell. It was taken with the Carnegie SWOPE 1-meter telescope in Chile using a filter that highlights the hot hydrogen gas of the shell. The now-quiescent star that produced the nova shell is indicated with red tick marks; it is far from the shell's center today. However, its measured motion across the sky places it at the red '+' in 1437. The position of the center of the shell in 1437 is at the green plus sign. The agreement of the 1437 positions of the shell center and of the old nova are the 'clock' that demonstrates that the old nova of 1437 A.D. really is the source of the shell. Credit: © K.

Using DNA to predict Schizophrenia, Autism

In vitro functional analysis showed that the CX3CR1-Ala55Thr mutation inhibited cell signaling induced by fractalkine, the ligand for CX3CR1. The combined data suggested that the variant Ala55Thr in CX3CR1 might result in the disruption of CX3CR1 signaling. Our results strengthen the association between microglia-specific genes and neurodevelopmental disorders.

Our results strengthen the association between microglia-specific genes and neurodevelopmental disorders.

Osaka University researchers show in a multi-institute collaboration that a single amino acid substitution in the protein CX3CR1 may act as predictor for schizophrenia and autism. Huntington’s disease, cystic fibrosis, and muscular dystrophy are all diseases that can be traced to a single mutation. Diagnosis in asymptomatic patient for these diseases is relatively easy – You have the mutation? Then you are at risk...
