Neoantigens and their potential applications in tumor immunotherapy
The incidence of malignant tumors is increasing, the majority of which are associated with high morbidity and mortality rates worldwide. The traditional treatment method for malignant tumors is surgery, coupled with radiotherapy or chemotherapy. However, these therapeutic strategies are frequently accompanied with adverse side effects. Over recent decades, tumor immunotherapy shown promise in demonstrating notable efficacy for the treatment of cancer. With the development of sequencing technology and bioinformatics algorithms, neoantigens have become compelling targets for cancer immunotherapy due to high levels of immunogenicity. In addition, neoantigen-based vaccines have demonstrated potential for cancer therapy, primarily by augmenting T-cell responses. Neoantigens have also been shown to be effective in immune checkpoint blockade therapy.
Metal fuel for carbon-free energy on Earth… and the Moon
One solution to the Eco, ‘Elephant in the Room’- of space launches.
Everything burns. Given the right environment, all matter can burn by adding oxygen, but finding the right mix and generating enough heat makes some materials combust more easily than others. Researchers interested in knowing more about a type of fire called discrete burning used ESA’s microgravity experiment facilities to investigate.
In a series of parabolic flights and on sounding rockets launched from Sweden, a team from Professor Jeffrey Bergthorson at McGill University in Canada and Eindhoven University of Technology in The Netherlands investigated burning iron powder in zero gravity. Their research was pure physics, the scientists wanted to know more about discrete burning whereby flames do not burn through fuel continuously but jump from one fuel source to another. This form of fire hardly occurs naturally on Earth, but an example is a forest fire where one tree burns completely and the fire jumps to the next tree when the temperature increases enough for combustion.
Burning iron dust in experiments on zero-g aircraft and rocket flights allowed for the iron particles to float and ignite discreetly. High-speed cameras captured the spectacle and allowed the researchers to better understand the phenomenon, resulting in computer models that showed the ideal conditions to burn the fuel on Earth.

Google’s top futurist Ray Kurzweil, renowned for his remarkably accurate tech predictions, has just moved his singularity date forward! He now claims that by 2039, humans will begin merging with machines, potentially transforming what it means to be human. In this video, we dive into Kurzweil’s latest forecast, exploring why he’s shaved six years off his original prediction and whether the age of human-machine hybrids is just 14 years away.
Known for his 86% accuracy rate in predicting the future, Kurzweil’s past successes, including the mainstream internet, wireless technology, and AI that understands speech, give weight to his bold claims. But is the idea of computers matching human brains by 2029 and a millionfold intelligence boost by 2045 truly within reach?
We’ll break down:

Plastic bottles transformed into Parkinson’s drug using bacteria
A drug to treat Parkinson’s disease can be made from waste plastic bottles using a pioneering method, a study shows. The approach harnesses the power of bacteria to transform post-consumer plastic into L-DOPA, a frontline medication for the neurological disorder. It is the first time a natural, biological process has been engineered to turn plastic waste into a therapeutic for a neurological disease, researchers say.
Scientists at the University of Edinburgh engineered E. coli bacteria to turn a type of plastic used widely in food and drink packaging—polyethylene terephthalate, or PET—into L-DOPA. The process involves first breaking down PET waste—some 50 million tonnes of which are produced annually—into chemical building blocks of terephthalic acid. Molecules of terephthalic acid are then transformed into L-DOPA by the engineered bacteria through a series of biological reactions.
Using the new technique to produce L-DOPA is more sustainable than traditional methods of making pharmaceuticals, which rely on the use of finite fossil fuels, the team says.
Ultrasound-based technology to deliver large therapeutics into cancer cells
In the study, the authors equipped these microbubbles with synthetic nucleic acid strands designed to bind with specific biochemical receptors that appear on the cell membranes of cancer cells but not healthy cells. They then tried several combinations of ultrasound frequencies and intensities to find the perfect pairing for opening pores in the cell membranes to allow the PROTACs to enter.
Once the optimal settings were identified, the researchers validated the platform by attaching fluorescent molecules to the PROTACs. They conducted separate experiments on cancer cells and healthy cells to compare the delivery efficiency. After a minute of ultrasound exposure, the cells treated with SonoPIN glowed seven times brighter than those treated with traditional PROTAC delivery methods, indicating that they were taking in many PROTACs. This resulted in half of the cancer cells self-destructing, while 99% of the healthy cells remained viable.
Moving forward, the researchers plan to test this approach in mouse models and have already applied for a patent covering the work. By injecting the PROTACs and cancer-seeking microbubbles into their veins and focusing the ultrasound waves on tumor locations, they believe SonoPIN could form a highly potent cancer-killing technology with few side effects. sciencenewshighlights ScienceMission.
Engineers have demonstrated a technique that uses microbubbles and ultrasound to help relatively large cancer drugs enter tumor cells and cause them to self-destruct.
Dubbed “Sonoporation-assisted Precise Intracellular Nanodelivery”—or SonoPIN for short—the technology caused 50% of targeted cancer cells in a benchtop experiment to self-destruct, while leaving 99% of non-targeted cells healthy. The results show promise for precisely delivering a wide variety of large-molecule therapeutics to cells with few off-target effects.
The research appears in the journal Proceedings of the National Academy of Sciences.
