Breath-based cancer test begins clinical trials in the UK

Published

on

The Cancer Research UK Cambridge Center has begun clinical trials for Cambridge-based Owlstone Medical’s Breath Biopsy® technology, a breathalyzer-type test that analyzes patients’ exhalations for biomarkers indicative of cancer. Samples from 1500 people, to include healthy participants as controls, will be used to determine whether the types of breath molecules assessed can positively identify both the presence of cancer and its type. The earlier cancer can be detected, the better the potential outcome for patients. Thus, noninvasive testing technology like Breath Biopsy® would be a very useful tool in cancer treatment.

The Breath Biopsy® test will search for what are called volatile organic compounds (VOCs), i.e., emissions triggered by cellular metabolic processes that enter the bloodstream. These act as biomarkers for cancer due to changes the disease makes to the body or made to the cancer growth itself. For example, during tumor growth, gene or protein changes can damage cell membranes and then release molecular byproducts specific to that type of tumor, VOCs, which are circulated in the lungs and exhaled. Normal human breath contains hundreds of VOCs from the body’s regular metabolic processes; however, certain types have been specifically linked to cancers, and researchers have been working to narrow the parameters to make clinically-useful tests, as is being done with Owlstone’s technology.

Early detection of cancer is one of the most significant tools that can impact its lethality, namely because most cancers aren’t found until they are at an advanced stage. Certain cancers, such as ovarian, lung, pancreatic, and colorectal, are hard to detect in their early stages, making survival rates low from the progression at the time of discovery. Also, tests for the presence of cancers are often invasive and expensive. Tools for accurate breath analysis identifying specific cancer biomarkers would provide significant improvement on both of these counts.

According to the National Cancer Institute, an estimated 1,735,350 new cases of cancer were diagnosed in 2018 in the United States, and 609,640 people died from the disease. Worldwide, that number is around 9 million per year. Statistics like these make the field of cancer research ripe for opportunities to address its numerous challenges with emerging and developing technologies.

Biotech has embraced cancer research and treatment as well as other fields not traditionally geared towards biological research. For example, artificial intelligence is aiding in cancer identification and prediction. Of further interest, genetic engineering is addressing environmental toxins known to cause cancer, and 3D printing is even being used in space to assess radiation’s effects on living tissue, a known factor in skin cancers. The push towards putting more humans in space will continue to expand the knowledge base in this area as science by NASA and similar national agencies and partners explore these issues as they relate to off-planet travel.

Tesla looks to upgrade Matrix Headlights with new features

According to the update, Tesla will work on improving the headlights when coming into contact with highly reflective objects, including road signs, traffic signs, and street lights. Additionally, pixel-level dimming will happen in two stages, whereas it currently performs with just one, meaning on or off.

Tesla is looking to upgrade its Matrix Headlights, a unique and high-tech feature that is available on several of its vehicles. The headlights aim to maximize visibility for Tesla drivers while being considerate of oncoming traffic.

The Matrix Headlights Tesla offers utilize dimming of individual light pixels to ensure that visibility stays high for those behind the wheel, while also being considerate of other cars by decreasing the brightness in areas where other cars are traveling.

Here’s what they look like in action:

As you can see, the Matrix headlight system intentionally dims the area where oncoming cars would be impacted by high beams. This keeps visibility at a maximum for everyone on the road, including those who could be hit with bright lights in their eyes.

There are still a handful of complaints from owners, however, but Tesla appears to be looking to resolve these with the coming updates in a Software Version that is currently labeled 2026.2.xxx. The coding was spotted by X user BERKANT:

According to the update, Tesla will work on improving the headlights when coming into contact with highly reflective objects, including road signs, traffic signs, and street lights. Additionally, pixel-level dimming will happen in two stages, whereas it currently performs with just one, meaning on or off.

Finally, the new system will prevent the high beams from glaring back at the driver. The system is made to dim when it recognizes oncoming cars, but not necessarily objects that could produce glaring issues back at the driver.

Tesla’s revolutionary Matrix headlights are coming to the U.S.

This upgrade is software-focused, so there will not need to be any physical changes or upgrades made to Tesla vehicles that utilize the Matrix headlights currently.

Elon Musk’s xAI has signed an agreement with the United States Department of Defense (DoD) to allow Grok to be used in classified military systems.

Previously, Anthropic’s Claude had been the only AI system approved for the most sensitive military work, but a dispute over usage safeguards has reportedly prompted the Pentagon to broaden its options, as noted in a report from Axios.

Under the agreement, Grok can be deployed in systems handling classified intelligence analysis, weapons development, and battlefield operations. 

The publication reported that xAI agreed to the Pentagon’s requirement that its technology be usable for “all lawful purposes,” a standard Anthropic has reportedly resisted due to alleged ethical restrictions tied to mass surveillance and autonomous weapons use.

Defense Secretary Pete Hegseth is scheduled to meet with Anthropic CEO Dario Amodei in what sources expect to be a tense meeting, with the publication hinting that the Pentagon could designate Anthropic a “supply chain risk” if the company does not lift its safeguards. 

Axios stated that replacing Claude fully might be technically challenging even if xAI or other alternative AI systems take its place. That being said, other AI systems are already in use by the DoD. 

Grok already operates in the Pentagon’s unclassified systems alongside Google’s Gemini and OpenAI’s ChatGPT. Google is reportedly close to an agreement that will result in Gemini being used for classified use, while OpenAI’s progress toward classified deployment is described as slower but still feasible. 

The publication noted that the Pentagon continues talks with several AI companies as it prepares for potential changes in classified AI sourcing.

Elon Musk denies Starlink’s price cuts are due to Amazon Kuiper

“This has nothing to do with Kuiper, we’re just trying to make Starlink more affordable to a broader audience,” Musk wrote in a post on X.

Elon Musk has pushed back on claims that Starlink’s recent price reductions are tied to Amazon’s Kuiper project.

In a post on X, Musk responded directly to a report suggesting that Starlink was cutting prices and offering free hardware to partners ahead of a planned IPO and increased competition from Kuiper.

“This has nothing to do with Kuiper, we’re just trying to make Starlink more affordable to a broader audience,” Musk wrote in a post on X. “The lower the cost, the more Starlink can be used by people who don’t have much money, especially in the developing world.”

The speculation originated from a post summarizing a report from The Information, which ran with the headline “SpaceX’s Starlink Makes Land Grab as Amazon Threat Looms.” The report stated that SpaceX is aggressively cutting prices and giving free hardware to distribution partners, which was interpreted as a reaction to Amazon’s Kuiper’s upcoming rollout and possible IPO.

In a way, Musk’s comments could be quite accurate considering Starlink’s current scale. The constellation currently has more than 9,700 satellites in operation today, making it by far the largest satellite broadband network in operation. It has also managed to grow its user base to 10 million active customers across more than 150 countries worldwide. 

Amazon’s Kuiper, by comparison, has launched approximately 211 satellites to date, as per data from SatelliteMap.Space, some of which were launched by SpaceX’s Falcon 9 rocket. Starlink surpassed that number in early January 2020, during the early buildout of its first-generation network.

Lower pricing also aligns with Starlink’s broader expansion strategy. SpaceX continues to deploy satellites at a rapid pace using Falcon 9, and future launches aboard Starship are expected to significantly accelerate the constellation’s growth. A larger network improves capacity and global coverage, which can support a broader customer base.

In that context, price reductions can be viewed as a way to match expanding supply with growing demand. Musk’s companies have historically used aggressive pricing strategies to drive adoption at scale, particularly when vertical integration allows costs to decline over time.
