A research team led by Prof. Wang Haoyi from the Institute of Zoology (IOZ) of the Chinese Academy of Sciences has developed a chimeric antigen receptor T (CAR-T) cell exhaustion model and a functional screening platform for identifying compounds that can rejuvenate exhausted T cells.

Using this innovative platform, the team identified the small-molecule compound miltefosine, which significantly enhances the tumor-killing activity of CAR-T cells. This study was published in Cell Reports Medicine on December 9.

T cell exhaustion is a differentiation state that arises when T cells are exposed to persistent antigen stimulation. This state is characterized by a progressive loss of effector functions, sustained expression of inhibitory receptors, impaired proliferation, and compromised mitochondrial respiration and glycolysis capacity.

As our devices multiply and data demands grow, traditional wireless systems are hitting their limits. To meet these challenges, we have turned to an innovative solution. At the University of Melbourne and Monash University, we have developed a dual-carrier Modular Optical Phased Array (MOPA) communication system. At the core of our innovation is a groundbreaking concept: a modular phased array.

This design is inspired by the quantum superposition principle, applying its logic to enhance technical performance and efficiency. This cutting-edge technology is designed to make indoor wireless networks faster, more reliable and more secure, while addressing the limitations of traditional systems. Our research is published in the IEEE Open Journal of the Communications Society.

“We thank Delta Electronics for choosing to grow in Texas,” said Adriana Cruz, executive director of the Texas Economic Development & Tourism Office. “As the most popular location in the U.S. for foreign direct investment over the last two decades and a national leader in advanced manufacturing, we know that Delta Electronics’ expanding facility will continue to thrive here in the Lone Star State. It’s thanks to innovative companies like Delta Electronics that Texas will continue to create good-paying careers in high-demand industries and build the technologies of the future. We congratulate our local and regional economic development partners in Plano on this remarkable win.”

Plano is the largest city in Collin County, with a population of more than 294,000.

Introduction Artificial intelligence has rapidly evolved over the last decade, leading to breakthroughs in natural language processing (NLP), machine learning, and multimodal applications. OpenAI’s O1 model exemplifies this innovation, offering capabilities that extend beyond traditional AI models. O1 is not just a tool; it is a revolutionary framework that brings advanced language understanding, multimodal integration, and real-time adaptability to the table. This comprehensive guide explores the intricacies of OpenAI’s O1 model, its applications, benefits, limitations, and how to optimize related content for search engine visibility.

Researchers have developed a tiny, room-temperature device that creates a special type of structured light called radially polarized photons, which are highly useful for secure communication, advanced imaging, and precision optical tools.

By carefully designing and positioning a quantum dot within a nanoantenna, they achieved high-quality light with more than 93% purity. This breakthrough helps improve the efficiency and practicality of devices that use structured light, paving the way for advancements in and optical technology.

A team led by Prof. Ronen Rapaport from the Racah School of Physics at The Hebrew University of Jerusalem has developed the new device that produces radially polarized photons at room temperature. This advancement offers new possibilities for both classical and quantum communication technologies.

A team of Indian astronomers has made a fascinating discovery that could change how we think about how planets are born. The team, led by Liton Majumdar from the National Institute of Science Education and Research (NISER) in Odisha, studied a unique triple-star system called GG Tau A, located 489 light-years away from Earth, as mentioned in the latest report by India Today.

Hip osteoarthritis (HOA), a prevalent condition among those aged 55 years and above, is a significant cause of joint pain and functional impairment and it contributes to the overall burden of chronic pain experienced by the elderly population. While platelet-rich plasma (PRP) and hyaluronic acid (HA) injections have emerged as innovative therapeutic approaches for managing osteoarthritis, their effectiveness in HOA remains a subject of contention. Therefore, the objective of this review was to assess the efficacy of PRP versus HA in terms of pain relief and functional outcomes for the management of HOA. We searched PubMed, Cochrane Library, and Google Scholar databases from 2013 to 2023 to identify pertinent randomized controlled trials (RCTs). A total of seven trials (478 participants) were included. The selected studies underwent quality assessment using the updated Cochrane risk of bias tool. The pain and functional outcomes were examined using measures of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain scale, visual analog scale (VAS), and Harris hip score (HHS). In the meta-analysis, standard mean differences (SMDs) along with 95% confidence intervals (CIs) to estimate overall effect magnitudes for continuous outcomes were extracted. Statistical significance was determined using p-values below 0.05. At six months, the PRP group experienced a significantly lower standard mean WOMAC pain score (SMD =-0.38, CI =-0.64 — 0.13; p = 0.03). No significant differences in WOMAC pain scores were noted at one to two months (SMD = 0.09, CI =-0.24, 0.43; p = 0.59), and at 12 months (SMD =-0.85, CI =-1.81, 0.12; p = 0.09). Similarly, for VAS, patients on PRP showed a slight improvement in their VAS scores at six months (SMD =-0.50, CI =-0.89,-0.12; p < 0.01). However, no significant differences in VAS between the PRP groups and the HA groups were observed at one to two months (SMD =-0.22, CI =-0.49, 0.04; p = 0.10) and at 12 months (SMD =-0.22, CI:-0.63, 0.19; p = 0.29). In terms of hip dysfunction, there was no statistically significant standard mean difference in HHS between the PRP and HA groups at six months (SMD = 0.02, CI =-0.40, 0.44; p = 0.93), and at 12 months (SMD =-0.31, CI =-0.32, 0.22; p = 0.73). This review and meta-analysis provide insights into emerging treatments for HOA, especially considering that PRP shows potential benefits and safety for patients with HOA during mid-term follow-up in a 12-month period. Nevertheless, it is necessary to conduct research that includes high-quality designs and larger sample sizes to validate the comparative efficacy of these treatments.

Generative artificial intelligence probably won’t change your life in 2025 — at least, not more than it already has, according to Google CEO Sundar Pichai.

When OpenAI launched ChatGPT two years ago, generative AI quickly captured the imagination of users around the world. Now, with the industry’s competitive landscape somewhat established — multiple big tech companies, including Google, have competing models — it’ll take time for another technological breakthrough to shock the AI industry into hyper-speed development again, Pichai said at the New York Times’ DealBook Summit last week.

“I think the progress is going to get harder. When I look at [2025], the low-hanging fruit is gone,” said Pichai, adding: “The hill is steeper … You’re definitely going to need deeper breakthroughs as we get to the next stage.”
