The DNA molecule inside the nucleus of any human cell is more than six feet long. To fit into such a small space, it must fold into precise loops that also govern how genes are turned on or off. New research indicates that 'jumping genes' play a surprising role in stabilizing the 3D folding patterns of the DNA molecule inside the cell's nucleus.

Halide perovskites have garnered attention because they're highly efficient at capturing energy in solar cells and efficient emitters in diodes. But researchers failed at making perovskite LEDs that emit blue light. Chemists succeeded, but X-ray studies of the LED's structure show that it's very sensitive to temperature, humidity and chemical environment. Hence environmental and chemical control is essential for stable operation. But these properties also allow for potentially broader use, such as sensors.

Smaller is better when it comes to microchips, researchers said, and by using 3D components on a standardized 2D microchip manufacturing platform, developers can use up to 100 times less chip space. A team of engineers has boosted the performance of its previously developed 3D inductor technology by adding as much as three orders of magnitudes more induction to meet the performance demands of modern electronic devices.

Take biomass-derived acetone -- common nail polish remover -- use light to upgrade it to higher-mass hydrocarbons, and, voila, you have a domestically generated product that can be blended with conventional jet fuel to fly while providing environmental benefits, creating domestic jobs, securing the nation's global leadership in bioenergy technologies, and improving U.S. energy security.

Astronomers have detected large amounts of oxygen in the atmosphere of one of the oldest and most elementally depleted stars known -- a 'primitive star' scientists call J0815+4729. This new finding provides an important clue on how oxygen and other important elements were produced in the first generations of stars in the universe.

3D microvessels have been created to observe how red blood cells transit ultra-small blood vessels. They squeeze single-file through microvessels to bring oxygen and nutrients. Red cells burdened with malaria stall, blocking the blood vessel. The platform is expected to have other uses in studies of how microvascular damage occurs in diabetes and sickle cell anemia. They might be further developed to supply blood circulation to organ repair patches or to 3D printed transplants.

For decades, it's been understood that water repellency is needed for surfaces to shed condensation buildup - like the droplets of water that form in power plant condensers to reduce pressure. New research shows that the necessity of water repellency is unclear and that the slipperiness between the droplets and solid surface appears to be more critical to the clearing of condensation. This development has implications for the costs associated with power generation and technologies like de-icing surfaces for power lines and aircraft.
