Huge ring-like structure on Ganymede’s surface may have been caused by violent impact

Researchers from Kobe University and the National Institute of Technology, Oshima College have conducted a detailed reanalysis of image data from Voyager 1, 2 and Galileo spacecraft in order to investigate the orientation and distribution of the ancient tectonic troughs found on Jupiter’s moon Ganymede. They discovered that these troughs are concentrically distributed across almost

Most Americans don’t have enough assets to withstand 3 months without income

A new study from Oregon State University found that 77% of low- to moderate-income American households fall below the asset poverty threshold, meaning that if their income were cut off they would not have the financial assets to maintain at least poverty-level status for three months. The study compared asset poverty rates in the U.S.

NASA’s Maven observes Martian night sky pulsing in ultraviolet light

Vast areas of the Martian night sky pulse in ultraviolet light, according to images from NASA’s MAVEN spacecraft. The results are being used to illuminate complex circulation patterns in the Martian atmosphere. The MAVEN team was surprised to find that the atmosphere pulsed exactly three times per night, and only during Mars’ spring and fall.

Why shaving dulls even the sharpest of razors

Razors, scalpels, and knives are commonly made from stainless steel, honed to a razor-sharp edge and coated with even harder materials such as diamond-like carbon. However, knives require regular sharpening, while razors are routinely replaced after cutting materials far softer than the blades themselves. Now engineers at MIT have studied the simple act of shaving

Researchers use InSight for deep Mars measurements

Using data from NASA’s InSight Lander on Mars, Rice University seismologists have made the first direct measurements of three subsurface boundaries from the crust to the core of the red planet. “Ultimately it may help us understand planetary formation,” said Alan Levander, co-author of a study available online this week in Geophysical Research Letters. While

Scientists propose a novel method for controlling fusion reactions

Scientists have found a novel way to prevent pesky magnetic bubbles in plasma from interfering with fusion reactions — delivering a potential way to improve the performance of fusion energy devices. And it comes from managing radio frequency (RF) waves to stabilize the magnetic bubbles, which can expand and create disruptions that can limit the

Recovering data: Neural network model finds small objects in dense images

In efforts to automatically capture important data from scientific papers, computer scientists at the National Institute of Standards and Technology (NIST) have developed a method that can accurately detect small, geometric objects such as triangles within dense, low-quality plots contained in image data. Employing a neural network approach designed to detect patterns, the NIST model

Scientists develop new way to deliver more drugs through the skin

Scientists from Nanyang Technological University, Singapore (NTU Singapore) and the Agency for Science, Technology and Research (A*STAR) have showed that applying “temporal pressure” to the skin of mice can create a new way to deliver drugs. In a paper published in Science Advances, the researchers showed that bringing together two magnets so that they pinch

Surface clean-up technology won’t solve ocean plastic problem

Clean-up devices that collect waste from the ocean surface won’t solve the plastic pollution problem, a new study shows. Researchers compared estimates of current and future plastic waste with the ability of floating clean-up devices to collect it — and found the impact of such devices was “very modest.” However, river barriers could be more

NASA sun data helps new model predict big solar flares

Using data from NASA’s Solar Dynamics Observatory, or SDO, scientists have developed a new model that successfully predicted seven of the Sun’s biggest flares from the last solar cycle, out of a set of nine. With more development, the model could be used to one day inform forecasts of these intense bursts of solar radiation.
