University scholars don't use social media to circulate scientific findings and engage their tech-savvy students, according to Michigan State University scholars.

People who have worked in both academia and the corporate world claim that the bias in academia is worse - which sounds odd, given the nature of academia. But statistics bear that out. Undergraduate representation of political views and handicapped people, for example, matches the general population, but once you reach the graduate, staff and faculty levels in colleges, diversity for people who are outside the political super-majority or who are handicapped disappears.

But even if you are part of the in crowd, it seems being a parent can take you right back out. 

A mixture of diamond nanoparticles and mineral oil easily outperforms other types of fluid created for heat-transfer applications, according to new research by Rice University.

Rice scientists mixed very low concentrations of diamond particles (about 6 nanometers in diameter) with mineral oil to test the nanofluid's thermal conductivity and how temperature would affect its viscosity. They found it to be much better than nanofluids that contain higher amounts of oxide, nitride or carbide ceramics, metals, semiconductors, carbon nanotubes and other composite materials.

The Rice results appeared this month in the American Chemical Society journal Applied Materials and Interfaces.

Researchers at the University of Adelaide have discovered that a commonly used anesthetic technique to reduce the blood pressure of patients undergoing surgery could increase the risk of starving the brain of oxygen.

Reducing blood pressure is important in a wide range of surgeries – such as sinus, shoulder, back and brain operations – and is especially useful for improving visibility for surgeons, by helping to remove excess blood from the site being operated on.

There are many different techniques used to lower patients' blood pressure for surgery – one of them is known as hypotensive anesthesia, which slows the arterial blood pressure by up to 40%.

Greenhouse gas emissions from food production may threaten the UN climate target of limiting global warming to 2 degrees Celsius, according to a paper from Chalmers University of Technology, Sweden. What is the data? No data needed.

"Obviously, we cannot go inside of the Earth to see what is happening there. However, the process of mantle convection should comply with fundamental physics laws, such as conservation of mass, momentum and energy. What we have done is to simulate the process of mantle convection by solving the equations which controls the process of mantle convection," says Li.
