Bursting air bubbles may play a key role in how glacier ice melts, Oregon State research suggests

CORVALLIS, Ore. – Oregon State University research has uncovered a possible clue as to why glaciers that terminate at the sea are retreating at unprecedented rates: the bursting of tiny, pressurized bubbles in underwater ice. Published today in Nature Geoscience, the study shows that glacier ice, characterized by pockets of pressurized air, melts much more quickly than the bubble-free sea ice or manufactured ice typically used to research melt rates at the ocean-ice interface of tidewater glaciers. Tidewater glaciers are rapidly retreating, the authors say, resulting in ice mass loss in Greenland, the Antarctic Peninsula and other glacierized regions around the globe. “We ...

Novel molecular design for enhanced efficacy and safety in radiotheranostics

Radiotheranostics embodies the convergence of diagnostic and therapeutic radiopharmaceuticals into a unified platform. In cancer treatment, radiotheranostic procedures typically involve the use of antibodies that bind to proteins abundantly found on the surface of cancerous cells. The antibodies are labeled with a suitable radioisotope, which facilitates imaging procedures used to diagnose cancer and can be used to target cancerous cells and bombard them with deadly radiation as a form of treatment. Although radiolabeled antibodies show promise as a treatment for cancer, several hurdles impede their clinical translation. ...

Human-AI collaboration improves source search outcomes

When artificial intelligence robots that have been designed to use algorithms to complete source search tasks, such as search and rescue operations during a fire, encounter a disturbance, they are often unable to complete their task. Proposed solutions have ranged from trying to improve algorithms to introducing additional robots, but these AI-driven robots still encounter fatal problems. Researchers have proposed a solution: a human-AI collaboration that takes advantages of the unique skills of the human brain to overcome challenges.

Low loss Mie scatterer enhanced Q and chirality control in silicon microring

Non-Hermitian systems with their spectral degeneracies known as exceptional points (EPs) have been explored for lasing, controlling light transport, and enhancing a sensor’s response. A ring resonator can be brought to an EP by controlling the coupling between its frequency degenerate clockwise and counterclockwise traveling modes. This has been typically achieved by introducing two or more nano-tips into the resonator’s mode volume. While this method provides a route to study EP physics, the basic understanding of how the nano-tips’ shape and size symmetry impact the system’s non-Hermicity is missing, along with additional loss from both in-plane and out-of-plane ...

Linking two solar technologies is a win-win for efficiency and stability

While conventional silicon-based solar cells have had an unmistakable impact on the buildout of renewable energy resources around the world, additional performance improvements have become increasingly difficult to make as the devices approach their practical efficiency limits. This constraint has prompted scientists to seek out new technologies that can be combined with silicon cells to unlock higher efficiencies. Solar cells made with crystals called perovskites are one such technology that have rapidly emerged as an appealing low-cost add-on, but perovskite cells are notoriously susceptible to voltage-induced ...

Seismologists use deep learning for improved earthquake forecasting

For more than 30 years, the models that researchers and government agencies use to forecast earthquake aftershocks have remained largely unchanged. While these older models work well with limited data, they struggle with the huge seismology datasets that are now available. To address this limitation, a team of researchers at the University of California, Santa Cruz and the Technical University of Munich created a new model that uses deep learning to forecast aftershocks: the Recurrent Earthquake foreCAST (RECAST). In a paper published today in Geophysical Research Letters, the scientists show how the deep learning model is more flexible ...

Better paths yield better AI

Deep Learning (DL) performs classification tasks using a series of layers. To effectively execute these tasks, local decisions are performed progressively along the layers. But can we perform an all-encompassing decision by choosing the most influential path to the output rather than performing these decisions locally? In an article published today in Scientific Reports, researchers from Bar-Ilan University in Israel answer this question with a resounding "yes". Pre-existing deep architectures have been improved by updating the most influential paths to the output. "One can ...
