NYU Abu Dhabi Develops Cancer-Fighting Nanospheres

The biotech breakthrough promises safer and more effective treatments using photodynamic and photothermal therapies.

A Research team from NYU Abu Dhabi’s Magzoub lab has made considerable advances in the fight against cancer using biocompatible nanospheres that have the potential to replace traditional forms of treatment.

The experiments trialed photodynamic therapy (PDT) and photothermal therapy (PTT), which use non-invasive light waves to destroy cancers, avoiding the well-known side effects of chemo and radiotherapy.

Photodynamic therapy works by releasing a torrent of reactive oxygen species (ROS) onto cancer cells, whereas photothermal therapy converts light into searing heat, destroying tumor tissues through hyperthermia.

The research team has detailed their findings in a paper entitled “pH-Responsive Upconversion Mesoporous Silica Nanospheres for Combined Multimodal Diagnostic Imaging and Targeted Photodynamic and Photothermal Cancer Therapy”. The literature goes on to explain how the nanospheres are able to protect encapsulated photosensitizers and photothermal agents from degrading, enabling them to be delivered directly to cancer cells.

Alongside thermal and fluorescent imaging, traditional magnetic resonance imaging (MRI) is also used for tumor detection and monitoring. Once cancer is detected, the PDT and PTT can kill tumors without leaving toxic traces in the body.

Loganathan Palanikumar, a senior researcher in the NYUAD Magzoub lab, explained the process, “To make PDT effective, we need enough photosensitizer in the tumor tissue, while PTT requires a substantial accumulation of photothermal agents within tumors”.

Mazin Magzoub, NYUAD associate professor of biology and Magzoub lab leader, added, “New therapeutic approaches are desperately needed to enhance the existing arsenal of cancer-fighting treatments”.

Magzoub lab’s new treatments offer real hope that cancers could soon be treated with minimal stress and danger to patients, leading to a brighter future free from one of the world’s most feared and destructive diseases.

Adobe Teases New AI Editing Tools And Updates In Premiere Pro

The video editing app will be enhanced with a generative extend tool, text-to-video, improved timeline waveforms, and more.



adobe teases new ai editing tools and updates in premiere pro

After launching the generative AI model Firefly last year, Adobe is now showcasing how the technology will be used in upcoming versions of the editing app Premiere Pro. In an early sneak peek, the company demonstrated several new features, including Object Addition and Removal, Generative Extend, and Text to Video.

The first new feature, Generative Extend, targets a common video editing problem by using AI to “Seamlessly add frames to make clips longer, so it’s easier to perfectly time edits and add smooth transitions”.

Meanwhile, Premiere Pro’s Object Addition & Removal tool will leverage Firefly’s generative AI to “Simply select and track objects, then replace them. Remove unwanted items, change an actor’s wardrobe or quickly add set dressings such as a painting or photorealistic flowers on a desk,” Adobe states.

Adobe also showcased another new feature that can automatically generate new film clips using a text prompt. To use the content creation tool, editors can “Simply type text into a prompt or upload reference images. These clips can be used to ideate and create storyboards, or to create B-roll for augmenting live action footage,” Adobe explained. The company seems to be commercializing this particular feature extremely quickly, considering generative AI video only appeared a few months ago.

The new additions to Premiere Pro will be added later this year, but Adobe is also introducing smaller improvements to the editing app in May. The changes include interactive fade handles to enable easier transitions, an Essential Sound badge that uses AI to “automatically tag audio clips as dialogue, music, sound effects or ambience, and add a new icon so editors get one-click, instant access to the right controls for the job”, along with effect badges and a new look for waveforms in the timeline.
