Stem cells can be made to grow around a three dimensional scaffold in your mouth in as quick as around nine weeks. Much better than dental implants!

Columbia University Medical Center Press Release.

The UK Metropolitan Police has been recording the frequency variations on the National Grid every second and a half for the past five years. When examining recordings, scientists are able to match the variations in the recordings with the database and establish exactly when the recording was made. If there are multiple matches, the recording was edited, and scientists can find out when. The process takes about 10 minutes.

Entangled photons have been able to instantaneously transmit their states over 500 m before, but the Chinese have managed to increase this range massively, allowing them to be used for communicative purposes.

What they did is email genetic code to a machine, which constructed DNA and implanted that in a virus cell, after removing the old DNA. The synthetic DNA then reproduced and it’s reproductions also carried the synthetic DNA. The reproduction is the ‘life’ bit.

Scientists have found the first multicellular animals that apparently live entirely without oxygen. The creatures reside deep in one of the harshest environments on earth: the Mediterranean Ocean's L'Atalante basin, which contains salt brine so dense that it doesn't mix with the oxygen-containing waters above. Previous samples taken from the water and sediments in the basin showed that single-celled life was present, but a new study published this week in BMC Biology has identified multi-cellular animals that apparently live and reproduce in the sediments under the salt brine. Italian and Danish researchers describe three new species of tiny animals called Loricifera.

Chinese doctors have used arsenic in the treatment of APL (leukemia) with cure rates of 90% since 1992 without the side-effects of chemo (hair loss, suppression of bone marrow function).

A paper from Shanghai shows that it works by targetting specific proteins that feed the cancer.

And we’ve known this since the 1890s. Experiments repeatedly show that multitasking basically makes you perform badly at any of the tasks you’re performing. Now, however, it turns out that not only do you do badly at the tasks, but it also destroys your capacity for reasoning.

This article walks quickly through the history of the research on multitasking and brings you up to date with methods to practically use single tasking, from the extreme in classrooms to the more mundane.

A team of US research scientists have made a startling breakthrough in solar-cell development, creating flexible wire-based cell substrates that use just one per cent of the silicon needed for brittle and comparatively heavy conventional cells.

Solar cells made from this material would not only be less expensive than current photovoltaics, but due to their low weight and bendable structure the could be used in a wide variety of applications.

The trick in this new method is to bundle one-micrometer-thick silicon wires and embed the resulting array vertically in a flexible polymer. Thus bundled, the paper claims, the array could capture and transmit up to 96 per cent of light in peak conditions while requiring only one per cent of the silicon needed by conventional cells.

The nanorobotic arm is built out of DNA origami: large strands of DNA gently encouraged to fold in precise ways by interaction with a few hundred short DNA strands. The products, around 100 nanometers in diameter, are eight times larger and three times more complex than what could be built with a simple crystalline DNA array, vastly expanding the space of possible structures. Other nanoscale structures or machines built by Dr. Seeman and his collaborators including a nanoscale walking biped, truncated DNA octahedrons, and sequence-dependent molecular switch arrays. Dr. Seeman has exploited structural features of DNA thought to be used in genetic recombination to operate his nanoscale devices, tapping into the very processes underlying all life.

“Scientists and engineers can use the 3D bio printers to enable placing cells of almost any type into a desired pattern in 3D,” Murphy said. “Researchers can place liver cells on a preformed scaffold, support kidney cells with a co-printed scaffold, or form adjacent layers of epithelial and stromal soft tissue that grow into a mature tooth

A synthetic chemical similar to the active ingredient in marijuana makes new cells grow in rat brains. What is more, in rats this cell growth appears to be linked with reducing anxiety and depression. The results suggest that marijuana, or its derivatives, could actually be good for the brain.

In this theory, time is split from space entirely. It’s a working model, but is still being refined as there are some flaws in it yet. It’s exciting because it does what Newton’s and Einstein’s theories can’t do, which is predict at the quantum graviton level.

After some teething problems and predicions about the world ending, it’s started and we’re still here: the first low power collisions have been made in two of the four sensor arrays, meaning more science is yet to come!

All these hygenic parents who continuously wash and disinfect their children and don’t like them to play in the dirt are doing their progeny a huge disservice.

Common bacterial species, known as staphylococci, which can cause inflammation when under the skin, are “good bacteria” when on the surface, where they can reduce inflammation.

By studying mice and human cells, researchers discovered that they did this by making a molecule, called lipoteichoic acid (or LTA) , which acted on keratinocytes, the main cell types found in the outer layer of the skin.
