New Gene research.

Look closely at the raw materials that make up any group of cells and you’ll notice some “noise,” a term scientists use to describe natural variations in cellular composition.

A little noise is normal. If a cell produces slightly above-average amounts of a particular protein, common processes like reproduction can continue to operate smoothly. But when things get too noisy, our cells’ machinery starts to misfire. These malfunctioning cells frequently produce mutant offspring that may die off immediately or contribute to the long-term growth of certain forms of cancer.

Education and socioeconomic status have been linked with cancer outcomes, but a new study now links higher education with the development of certain types of cancer.

The large observational study, published in the Journal of Epidemiology and Community Health, reports that a high level of education is associated with an increased risk of brain tumors. The study is based on data from 4.3 million Swedish adults who were monitored between 1993 and 2010. Overall, 5,735 men and 7,101 women developed a brain tumor during the observation period.

Men with at least three years of university-level education had a 19% greater risk of developing gliomas than men with only a compulsory level of education (nine years). Women with the same level of education had a 23% increased risk of gliomas and a 16% increased risk of meningiomas. Marital status and amount of disposable income only slightly affected the risk among men but not among women. Single men had a lower risk of glioma but a higher risk of meningiomas. Occupation also influenced brain tumor risks among men and women: men in professional and management roles had a 20% increased risk of gliomas and a 50% increased risk of acoustic neuromas; women in these roles had a 26% increased risk of gliomas and a 14% increased risk of meningiomas.

Microsoft’s amazing HoloLens is the world’s first stand-alone headset that lets users see virtual objects and environments as if they existed in the real world. This device’s entertainment potential is practically unlimited, but as a Hackathon team recently demonstrated, it can also be used to rewire a malfunctioning brain.

A Microsoft employee suffering from myoclonus-dystonia —a condition where the misfiring of the brain causes uncontrollable muscle spasms—discovered that she could regain control during a spasm by looking at her partner’s feet rather than her own. And that’s how she got her great idea: Why not use the HoloLens to retrain the brain and get it to act differently? To that end, she recruited the Microsoft Hackathon team to put the idea to the test.

Beijing and Moscow have agreed that they will “proactively consider strengthening bilateral coordinating measures” to tackle the threat posed by the US and the Republic of Korea’s plan to deploy a powerful antimissile system on the Korean Peninsula.

The consensus was reached during the fourth China-Russia Northeast Asia security consultation in Mosow on Thursday, according to a news release of the Foreign Ministry on Friday.

Assistant Minister of Foreign Affairs Kong Xuanyou and Russian Deputy Foreign Minister Igor Morgulov co-chaired the meeting.

We always hear how bad Russia is; etc. We never hear about these stories where they helped the US.

A U.S. Air Force surveillance plane making a routine flight over Russia to fulfill a treaty obligation was forced to make an emergency landing in eastern Russia earlier this week after experiencing a problem with its landing gear, a Pentagon spokes person told Fox News.

The unarmed American military plane had Russian officials on board as part of the 1992 Open Skies Treaty, which bounds 34 nations, including Russia and the United States, to allow military inspection flights to ensure compliance to long standing arms-control treaties and to offer greater transparency into each nation’s military capabilities.

“On July 27, a U.S. Open Skies Treaty observation aircraft took off from Russian airfield Ulan Ude to begin a Treaty observation flight but the aircraft landing gear did not fully retract,” Lt. Col. Michelle L. Baldanza, a Pentagon spokes person, said in an emailed statement to Fox News.

Among the intriguing issues in plasma physics are those surrounding X-ray pulsars—collapsed stars that orbit around a cosmic companion and beam light at regular intervals, like lighthouses in the sky. Physicists want to know the strength of the magnetic field and density of the plasma that surrounds these pulsars, which can be millions of times greater than the density of plasma in stars like the sun.

Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have developed a theory of waves that can infer these properties in greater detail than in standard approaches. The new research analyzes the plasma surrounding the pulsar by coupling Einstein’s theory of relativity with , which describes the motion of subatomic particles such as the atomic nuclei—or ions—and electrons in plasma. Supporting this work is the DOE Office of Science.

Quantum field theory

The key insight comes from , which describes charged particles that are relativistic, meaning that they travel at near the speed of light. “Quantum theory can describe certain details of the propagation of waves in plasma,” said Yuan Shi, a graduate student in the Princeton Program in Plasma Physics and lead author of a paper published July 29 in the journal Physical Review A. Understanding the interactions behind the propagation can then reveal the composition of the plasma.
