Brandon Jackson, a doctoral candidate in mechanical engineering at Michigan Technological University, has created a new computational model of an electrospray thruster using ionic liquid ferrofluid—a promising technology for propelling small satellites through space. Specifically, Jackson looks at simulating the electrospray startup dynamics; in other words, what gives the ferrofluid its characteristic spikes.

Arctic winter warming events – winter days when temperatures peak above minus 10 degrees Celsius – are a normal part of the Arctic climate over the ice-covered Arctic Ocean, but new research finds they are becoming more frequent and lasting longer than they did three decades ago.

A new study analyzing winter air temperatures over the Arctic Ocean from 1893 to 2017 shows that since 1980, an additional six Arctic winter warming events are occurring each winter at the North Pole and these events are lasting about 12 hours longer, on average. In December 2015, scientists recorded a temperature of 2.2 degrees Celsius (36 degrees Fahrenheit) in the Central Arctic, the warmest temperature ever recorded in this region from December through March.

Doctors can’t predict who will develop Type 1 diabetes, a chronic autoimmune disease in which one’s own immune system destroys the cells needed to control blood-sugar levels, requiring daily insulin injections and continual monitoring.

Precipitation extremes are of general interest due to their profound impacts on the society, economy, human safety, and the natural environment. Precipitation extremes exhibit high spatiotemporal variation in terms of both their frequency and intensity relative to the mean precipitation, so it is always difficult to detect extreme events and their underlying related mechanisms.

Changes in the visual systems of newly diagnosed Parkinson’s disease patients may provide important biomarkers for the early detection and monitoring of the disease, according to a new study published online in the journal Radiology.

The future cost of energy storage technologies can now be predicted under different scenarios, thanks to a new tool created by Imperial researchers.

Using a large database, the team can predict how much consumers will have to pay in the future for energy storage technologies based on cumulative installed capacity, current cost and future investment.

Can you imagine fully charging your cell phone in just a few seconds? Researchers in Drexel University’s College of Engineering can, and they took a big step toward making it a reality with their recent work unveiling of a new battery electrode design in the journal Nature Energy.

The team, led by Yury Gogotsi, PhD,Distinguished University and Bach professor in Drexel’s College of Engineering, in the Department of Materials Science and Engineering, created the new electrode designs from a highly conductive, two-dimensional material called MXene. Their design could make energy storage devices like batteries, viewed as the plodding tanker truck of energy storage technology, just as fast as the speedy supercapacitors that are used to provide energy in a pinch — often as a battery back-up or to provide quick bursts of energy for things like camera flashes.

In their work toward 3-D printing transplantable tissues and organs, bioengineers and scientists from Rice University and Baylor College of Medicine have demonstrated a key step on the path to generate implantable tissues with functioning capillaries.

Supernovas — the violent endings of the brief yet brilliant lives of massive stars — are among the most cataclysmic events in the cosmos. Though supernovas mark the death of stars, they also trigger the birth of new elements and the formation of new molecules.

NASA satellites gave the Eastern Pacific Ocean's Hurricane Eugene an "eye exam" as it studied the storm in infrared and visible light. NASA satellite imagery taken at different times showed Eugene's eye open and closed.
