In a study published today in Science Translational Medicine, a research team led by biologists Joon Haeng Rhee and Jung-Joon Min from Chonnam National University in South Korea describe a new immunotherapy in which a bioengineered strain of Salmonella is converted into a biological version of the fabled Trojan Horse. Once inside an unsuspecting tumor, the modified bacteria transmits a signal that triggers nearby immune cells into launching an attack on the malignant cells.
In preliminary tests, the technique shrunk tumors in more than half of the mice who received injections of the commandeered bacteria. It's preliminary, but the researchers are hopeful that this form of immunotherapy will be both safe and effective in humans.

"We planned to send an expedition to the Iranian desert Lut, intending to find a concentration of extraterrestrial material, meteorites." Grokhovsky said.
A team of 4 people, all employees of the laboratory Extra Terra Consortium made a trial expedition to Iran.
According to the scientist, the expedition was successful. "The team managed to collect a sufficient number of extraterrestrial materials, with the support of their Iranian colleagues from the University of Kerman."
Experts believe that about 80% of the samples which have been brought back from the desert actually have extraterrestrial origins. Russian scientists left part of the found samples in Iran for their colleagues from Kerman University.
Talking about the findings of the team, Grokhosvky told Sputnik Persian that, "During the field work, about 13 kilograms of the samples, which is considered to be meteorite, were found. Half of the found fragments have remained with our Iranian colleagues; the other half has arrived at our test lab. For now the samples have been measured and entered into the catalogue."
He further said that it turned out that many fragments were remains of a meteor shower. About 70 individual pieces were collected with 10-12 of these fragments belonging to the same type of meteorite.
The high-speed rail service will also contribute to closer across-the-board ties between Russia and China and will bring in new investments in Russia.

Described as a first of its kind, footage of "elusive blue jets" was filmed in 2015 over the Bay of Bengal by European Space Agency astronauts using the most sensitive camera on the space station.
Gigantic electrical discharges and jets can be seen in the footage with numerous flashes visible within the storm clouds. A number of blue-purple discharges are followed by a "pulsating blue jet" shooting up out of the cloud.
"The blue discharges and jets are examples of a little-understood part of our atmosphere," the ESA said in a statement. "Electrical storms reach into the stratosphere and have implications for how our atmosphere protects us from radiation."
Look up tonight! Stunning 'Snow moon' eclipse and a mysterious green comet are set to appear in the night sky

And just a few hours later, Comet 45P - also known as the New Year comet - will make its closest approach to the Earth.
The full event will be live streamed on Slooh, who will be filming the skies from the Canary Islands.
An eclipse of the moon occurs when the sun, Earth and moon line up, with Earth in the middle.
This alignment causes the Earth's shadow to fall on the moon, creating a lunar eclipse.

Researchers at the Fraunhofer Institute for Cell Therapy and Immunology in Potsdam, Germany and their international counterparts have made a discovery, after conducting a long-term experiment which took place on the International Space Station (ISS), that algae can survive extreme conditions in outer space. The research findings could benefit industrial applications and perhaps, even a mission to Mars.
The experiment looked to see if algae could spend two years on the outside of the ISS. The algae, which were of the Sphaerocystis species, spent 530 days on a panel outside the space station.

The international team of astronomers observed the white dwarf WD 1425+540, about 170 light-years from Earth in the constellation Boötes (the Herdsman) . While studying the white dwarf's atmosphere using both the NASA/ESA Hubble Space Telescope and the W. M. Keck Observatory the team found evidence that an object rather like a massive comet was falling onto the star, getting tidally disrupted while doing so.
The team determined that the object had a chemical composition similar to the famous Halley's Comet in our own Solar System, but it was 100 000 times more massive and had twice the proportion of water as its local counterpart. Spectral analysis showed that the destroyed object was rich in the elements essential for life, including carbon, oxygen, sulphur and even nitrogen .

Liquid breathing involves using biomedical technology to ventilate the lungs of air-breathing organisms with an oxygen-rich liquid. The technology "allows the animals to breathe underwater and stay there for long periods of time," the Foundation for Advanced Research (FAR) press service told Izvestia newspaper.
Mice, hamsters and dogs will become test subjects during the study, the scientists told the paper. During the liquid breathing experiments, "the lungs of the animal are filled with a special liquid, after which it's immersed in water for a period of time. After the test, the animal is examined and then it remains under supervision for prolonged periods of time" to study the long-term effects of the technology, FAR said.
Such tests have already been carried out successfully, with a dachshund that experienced liquid breathing two years ago still alive and well, and being looked after by one of the foundation's employees.

Experiments conducted by planetary physicist Kevin Grazier of NASA's Jet Propulsion Laboratory suggest Saturn plays an equally important role in shielding Earth from harmful asteroids.
Grazier's findings also suggest that Jupiter, previously considered to be the Earth's only shield, could have played a part in the formation of all life on our blue planet by aiding the delivery of the building blocks for organic existence.

"The obtained filter material by far exceeds all existing analogues in its ability to stop the most dangerous aerosol particles such as viruses, toxins, allergens. This technology could usher in a wide variety of protective materials for medical, military and other purposes," Grigoryev explained.
