Recent research shows that plant-based plastics release far fewer microplastics than traditional plastics in marine environments, suggesting they could be a more environmentally friendly option. However, continued research is crucial to fully assess their impact.

A recent study has discovered that a new plant-based plastic material releases nine times fewer microplastics compared to traditional plastic when subjected to sunlight and seawater. Conducted by researchers from the University of Portsmouth and the Flanders Marine Institute (VLIZ) in Belgium, the study examined the degradation of two different types of plastic under harsh conditions.

A bio-based plastic material made from natural feedstocks held up better when exposed to intense UV light and seawater for 76 days — the equivalent of 24 months of sun exposure in central Europe — than a conventional plastic made from petroleum derivatives.

Researchers have developed a machine learning model that generates quantum circuits from text descriptions, similar to how models like Stable Diffusion create images. This method, improves the efficiency and adaptability of quantum computing.

One of the most important recent developments in Machine Learning (ML) is generative models such as diffusion models. These include Stable Diffusion and Dall.e, which are revolutionizing the field of image generation. These models are able to produce high-quality images based on text descriptions.

“Our new model for programming quantum computers does the same but, instead of generating images, it generates quantum circuits based on the text description of the quantum operation to be performed,” explains Gorka Muñoz-Gil from the Department of Theoretical Physics of the University of Innsbruck, Austria.

Researchers have developed techniques to manufacture different types of glass in space, uncovering potential for advancements in optical technology.

Thanks to human ingenuity and zero gravity, we reap important benefits from science in space. Consider smartphones with built-in navigation systems and cameras.

Advanced observations by the JWST indicate that early galaxies matured faster and were less chaotic, challenging previous theories of galaxy evolution.

New research has revealed that the Universe’s early galaxies were less turbulent and developed more rapidly than previously believed. This research, led by an international team from Durham University, utilized the James Webb Space Telescope (JWST) to find evidence of bar formation when the Universe was only a few billion years old.

Researchers at Rensselaer Polytechnic Institute have fabricated a device no wider than a human hair that will help physicists investigate the fundamental nature of matter and light. Their findings, published in the journal Nature Nanotechnology, could also support the development of more efficient lasers, which are used in fields ranging from medicine to manufacturing.

The universe is expanding at an accelerating rate but Einstein’s theory of General Relativity and our knowledge of particle physics predict that this shouldn’t be happening. Most cosmologists pin their hopes on Dark Energy to solve the problem. But, as Claudia de Rham argues, Einstein’s theory of gravity is incorrect over cosmic scales, her new theory of Massive Gravity limits gravity’s force in this regime, explains why acceleration is happening, and eliminates the need for Dark Energy.

You can see Claudia de Rham live, debating in ‘Dark Energy and The Universe’ alongside Priya Natarajan and Chris Lintott and ‘Faster Than Light’ with Tim Maudlin and João Magueijo at the upcoming HowTheLightGetsIn Festival on May 24th-27th in Hay-on-Wye.

This article is presented in association with Closer To Truth, an esteemed partner for the 2024 HowTheLightGetsIn Festival.

Physicists call the dark energy that drives the universe “the cosmological constant.” Now the largest map of the cosmos to date hints that this mysterious energy has been changing over billions of years.

Researchers at Texas Children’s Cancer Center and the Center for Cell and Gene Therapy at Baylor College of Medicine, Texas Children’s Hospital and Houston Methodist published results of a phase I clinical trial of a novel immunotherapy for high-risk sarcomas in the journal Nature Cancer.

The therapy uses chimeric antigen receptor (CAR) T cells engineered to target the HER2 protein, which is overexpressed on the surface of sarcoma cells. Sarcoma is a type of solid cancer that develops in the bones and soft tissues. The HEROS 2.0 trial showed that this therapeutic approach is safe and is associated with clinical benefit.

“CAR T cell therapy has been a highly successful strategy for recurrent or high-risk leukemias or lymphomas, but challenges remain in using this therapy for solid tumors,” said first and corresponding author Dr. Meenakshi Hegde, associate professor of pediatrics – hematology and oncology at Baylor and pediatric oncologist at Texas Children’s Cancer Center. “The results of this trial show that we are moving the dial in harnessing the power of CAR T cells as an effective anticancer therapy for sarcomas.”
