Their Immersive Technology Lab received a national innovation award for a project that uses VR to better translate ...

Artificial intelligence can transform medicine in a myriad of ways, including its promise to act as a trusted diagnostic aide to busy clinicians. Over the past two years, proprietary AI models, also known as closed-source models, have excelled at solving hard-to-crack medical cases that require complex clinical reasoning. Notably, these closed-source AI models have outperformed open-source ones, so-called because their source code is publicly available and can be tweaked and modified by anyone. Has open-source AI caught up? The answer appears to be yes, at least when it comes to one such open-source AI model, according to the findings ...

A predator’s gotta eat, but sometimes what they eat harms people sharing the landscape, and that often leads to the carnivore’s death.   Fortified corrals are one strategy used in Tanzania to protect both livestock and vulnerable carnivore species. But then where do lions, leopards and hyenas go for dinner? Do they feed on the next herd over?   A new study led by Colorado State University has found that good fences truly do make good neighbors because fortified enclosures also benefit livestock keepers who live nearby. Instead of dining on easier meals next-door and negatively impacting neighbors who don’t ...

Results from the NRG Oncology GOG-0263 phase III clinical trial testing the addition of cisplatin-based chemotherapy to adjuvant radiotherapy following radical hysterectomy and lymphadenectomy for patients with early-stage, intermediate-risk cervical carcinoma indicated that the addition of chemotherapy did not improve outcomes for patients and led to increased toxicity for patients. The outcomes of this trial support the use of the current standard of care using adjuvant radiotherapy alone following surgery. These results were ...

Alternative RNA splicing is like a movie editor cutting and rearranging scenes from the same footage to create different versions of a film. By selecting which scenes to keep and which to leave out, the editor can produce a drama, a comedy, or even a thriller—all from the same raw material. Similarly, cells splice RNA in different ways to produce a variety of proteins from a single gene, fine-tuning their function based on need. However, when cancer rewrites the script, this process goes awry, fueling tumor growth and survival. In a recent study reported in the Feb. 15 issue of Nature ...

A team of researchers from the University of Ottawa has made significant strides in understanding the ionization of atoms and molecules, a fundamental process in physics that has implications for various fields including x-ray generation and plasma physics. Think about atoms - the building blocks of everything around us. Sometimes, they lose their electrons and become charged particles (that's ionization). It happens in lightning, in plasma TVs, and even in the northern lights. Until now, scientists thought they could only control this process in limited ways. Led by Ravi Bhardwaj, Full Professor at uOttawa’s Department of Physics, and PhD student Jean-Luc Begin, in collaboration ...

We’ve mapped nearly all of Mars’ surface from orbit, yet we know less about Earth’s ocean floor — almost 75% remains unmapped in high resolution. This terrestrial blind spot is driving NJIT Mathematics Professor Eliza Michalopoulou’s latest research, funded by the Office of Naval Research (ONR). The project aims to improve how scientists explore the vast, uncharted ocean floor through sound. “Mapping the seabed is a challenging endeavor due to the extreme conditions,” said Michalopoulou, ...
