While the Diprotodon -- the extinct megafauna species that is distantly related to wombats but was the size of a small car -- is commonly (but incorrectly) thought of as Australia's 'giant wombat', researchers have shed light on a large species that does belong in the modern-day wombat family. The complete skull of this true fossil giant wombat, found in a Rockhampton cave in Queensland, Australia and estimated to be around 80,000 years old, has been described for the first time.

Researchers calculated that 74 metric tons of microplastics are dropping out of the atmosphere onto the city annually, the equivalent of more than 3 million plastic bottles falling from the sky.

Self-driving cars need to implement efficient, effective, and accurate detection systems to provide a safe and reliable experience to its users. To this end, an international research team has now developed an end-to-end neural network that, in conjunction with the Internet-of-Things technology, detects object with high accuracy (> 96%) in both 2D and 3D. The new method outperforms the current state-of-the-art methods and the way to new 2D and 3D detection systems for autonomous vehicles.

Wildlife researchers have completed a study that may settle the question of why, in October 2009, a group of coyotes launched an unprovoked fatal attack on a young woman who was hiking in a Canadian park. Researchers concluded that the coyotes were forced to rely on moose instead of smaller mammals for the bulk of their diet -- and as a result of adapting to that unusually large food source, perceived a lone hiker as potential prey.

The reliability of data storage and writing speed in advanced magnetic devices depend on drastic, complex changes in microscopic magnetic domain structures. However, it is extremely challenging to quantify these changes, limiting our understanding of magnetic phenomena. To tackle this, researchers developed, using machine learning and topology, an analysis method that quantifies the complexity of the magnetic domain structures, revealing hidden features of magnetization reversal that are hardly seen by human eyes.

A new automated approach to detect doxing -- a form of cyberbullying in which certain private or personally identifiable information is publicly shared without an individual's consent or knowledge -- may help social media platforms better protect their users, according to researchers.

Researchers have discovered web-like plasma structures in the Sun's middle corona. The researchers describe their innovative new observation method, imaging the middled corona in ultraviolet (UV) wavelength. The findings could lead to a better understanding of the solar wind's origins and its interactions with the rest of the solar system.

Researchers have developed a new transparent gold nanocoating that harnesses sunlight to heat the lenses of glasses, thereby preventing them from fogging in humid conditions. This coating could potentially also be applied to car windshields.

How are galaxies born, and what holds them together? Astronomers assume that dark matter plays an essential role. However, as yet it has not been possible to prove directly that dark matter exists. A research team has now measured the survival rate of antihelium nuclei from the depths of the galaxy -- a necessary prerequisite for the indirect search for Dark Matter.

MIT researchers developed a scalable fabrication technique to produce ultrathin, flexible, durable, lightweight solar cells that can be stuck to any surface. Glued to high-strength fabric, the solar cells are only one-hundredth the weight of conventional cells while producing about 18 times more power-per-kilogram.
