In 2016, LJ was just 19 years old and on the brink of a transformative journey. After graduating from college with commendable grades, he was excited to explore the world. However, he soon discovered what seemed like a harmless lump on his neck.

“I remember finding a large lump on my neck,” he recalls. “I felt exhausted all the time. It started to interfere with my life.”

Despite visiting the doctor, LJ was convinced it was “just an infection” and delayed follow-up appointments until he was urgently called back for test results. “The doctor told me, ‘This is leukemia,’” LJ reflects. “I couldn’t believe it—cancer at my age? I didn’t even know what leukemia was back then.”

We spoke with LJ about his inspiring cancer journey, how photography became a vital coping tool during a year of intensive treatment, and how Macmillan Cancer Support played a crucial role in guiding him through pivotal decisions in his life.

LJ’s Story: A Life-Altering Diagnosis

In 2016, LJ received a diagnosis of acute lymphoblastic lymphoma, an aggressive cancer necessitating immediate action. Instead of diving into student life, he faced grueling hospital stays with a bleak prognosis of only a 5% survival rate.

“I was stuck in a hospital bed undergoing chemotherapy, surgeries, radiation therapy, and stem cell transplants… it was overwhelming,” LJ shares. “I endured numerous procedures and constant needles…”

“The hardest part is hearing that treatments aren’t effective,” he continues. “Chemotherapy fails, radiotherapy fails, surgery fails. There’s a lot of chaos and distress. Despite your hopes and beliefs, things might not go as planned.”

Finding Freedom in Photography

Before his diagnosis, LJ was a typical teenager, exploring creativity, traveling, skateboarding, and enjoying time with friends in London. Suddenly, he found himself “isolated in a room or a ward”, painfully aware that days felt like they had no end.

As the walls of his physical environment closed in, LJ discovered that photography and videography opened a new world for him. By documenting his experiences through photos and videos, he created a much-needed escape: a creative outlet and a way to process his reality.

“I had a little Canon PowerShot G7 camera at the time,” he shares. “Taking photos helped me express my feelings without leaving the hospital. I could capture my emotions and enjoy the creative process. It was incredibly fulfilling.”

Macmillan’s guidance empowered LJ to make important decisions during critical moments

Macmillan Support During a Crucial Time

During this challenging treatment phase, LJ came across vital information from Macmillan Cancer Support in the form of a pamphlet, which provided essential guidance for his future. “I received a leaflet from Macmillan about cancer and fertility,” he states.

“After multiple surgeries, fertility can be affected, and I learned that I might not be able to have children,” he reveals. “The insights in that pamphlet helped me comprehend my situation significantly.”

Now, a decade after his diagnosis and in remission, the support from Macmillan has made a lasting impact on LJ’s life. “Without that booklet, I would have likely made decisions I’d regret,” he states.

Gifts in wills fund over a third of Macmillan’s services, including the resources that aided LJ, ensuring continued access to trusted cancer support, from helplines to informational booklets and community support across the UK. Having clear guidance and support from Macmillan was pivotal for LJ in making informed decisions about sperm storage at a critical time.

Faraday 2 battery developed by Superdielectrics

Superdielectrics

The innovative battery storage solution, utilizing SuperCapacitor Technology, may “jump” traditional lithium-ion batteries, transforming the landscape for renewable energy storage and use, according to its creator.

On July 8th, British firm SuperDielectrics unveiled its new prototype storage system, dubbed the Faraday 2, at an event in central London. Incorporating a polymer designed for contact lenses, this system boasts a lower energy density than lithium-ion batteries but claims numerous advantages, such as quicker charging, enhanced safety, reduced costs, and a recyclable framework.

“The current energy storage market at home is reminiscent of the computer market around 1980,” said SuperDielectrics’ Marcus Scott while addressing journalists and investors. “Access to clean, reliable, and affordable electricity isn’t a future goal; it’s now a practical reality, and we believe we are creating the technology to support it.”

Energy storage is pivotal for the global transition to green energy, crucial for providing stable electricity despite the intermittent nature of wind and solar power. While lithium-ion batteries dominate the storage technology market, they present challenges, including high costs, limited resources, complex recycling processes, and safety risks like overheating explosions.

With its aqueous battery design grounded in supercapacitor technology, SuperDielectrics aims to address these challenges. Supercapacitors store energy on material surfaces, facilitating extremely rapid charge and discharge cycles, albeit with lower energy density.

The company’s design employs a zinc electrolyte, separated from the carbon electrode by a polymer membrane. SuperDielectrics asserts that this membrane technology is cost-effective, utilizing abundant raw materials, thus unlocking a new generation of supercapacitors with significant energy storage capabilities.

During the event, the company’s CEO Jim Heathcote mentioned that the technology could outperform lithium-ion systems in renewable energy storage.

The Faraday 2 builds on the earlier Faraday 1 prototype launched last year, claiming to double the energy density. The Faraday 2 operates at 1-40 Wh/kg, allowing for faster charging times, which will harness fleeting spikes in renewable energy production, as noted by Heathcote.

However, Gareth Hinds from the UK National Physical Laboratory points out that the technology still lags behind lithium-ion batteries, which can achieve around 300 Wh/kg at the cell level. Andrew Abbott of the University of Leicester adds that the energy density now offered by SuperDielectrics is akin to that of lead-acid batteries commonly used in automobiles and backup power systems. “There are no immediate plans among leading manufacturers to transition,” he states.

Marcus Newborough, scientific advisor at SuperDielectrics, acknowledges that they are still “on a journey” to enhance the system’s energy density. “We are aware of our high theoretical energy density,” he mentioned, noting the company’s commitment to realizing this potential in the coming years, aiming for a commercial energy storage solution ready for launch by the end of 2027.

Despite the optimism, Hinds remains skeptical about the technology competing with lithium-ion batteries regarding energy density. “Clearly, it’s an early-stage development, and while they continue to push for higher energy density, achieving lithium-ion levels is a significant challenge due to strict limitations,” he comments.

Nonetheless, he suggests that there could be a market for larger storage solutions that provide lower energy density but at a much more affordable price than lithium-ion batteries and with a longer lifespan.

Sam Cooper from Imperial College, London, concurs: “If we can develop a system offering equal energy storage capacity to the Tesla Powerwall, regardless of size or weight, and at a cost of 95% less, that would represent a groundbreaking achievement.”

Behind the Lens: Bending Back for Good Fortune in Global Development

gMy experience in Columbia and online rowing has shaped my artistic expression. My identity blossomed within a country rife with superficial, conservative values—where happiness coexists with violence, and where men pray to virgins while sometimes resorting to lethal actions against others.

The internet offered me a sanctuary, a place where I could explore who I wanted to be. As a sensitive young girl, it helped me discover my personality and interests, even as it distanced me from the tangible world, leaving me to ponder my existence and perspectives.

In 2023, after leaving home and embarking on my journey of self-discovery, I became enthralled by online self-help culture, particularly the pseudo-psychic phenomenon known as Hashtag Lucky Girl Syndrome. TikTok promised a new life of dreams through specific audio tracks, like “layer frequency,” gentle synths, and mystical elements such as Reverse Wispel’s Ayyams. Users claimed, “If you hear this, step into a new chapter. Expect your blessing within 24 hours.”

I longed to embody this lucky girl who could attain all her desires by meticulously following these rituals. While part of me engaged with it ironically, another segment of my being genuinely resonated with it.

This image embodies Lucky Girl Syndrome, a facet of my project born from deep online exploration. I aimed to engage with this obsession to distance myself. In my bedroom, I craft mood boards, adorning the walls with printed affirmations sourced online. Some resonate deeply, while others satirize the culture with humor: “I’m in my safe zone.” “I’m not clenching my chin right now.” “The angel is observing 333.” “I shine”; “Click to save.”

I noticed that these positive visuals often featured luminous orbs, symbolizing the feelings we aspire to embody. I aimed to construct a theatrical environment that could personify various interpretations of lucky girls. This includes Yogi’s version of a lucky girl who embraces retrospection for fortune.

The Lucky Girl Syndrome Project represents a hopeful critique of how girls like me find solace in our devices and personal spaces as gateways to health and self-improvement. Yet, it extends beyond that; I’m keenly interested in questioning the constructs surrounding female identity. Cosmetic surgery has become commonplace in a culture where beauty equates to worth, while Catholic morals continue to influence gender roles, family dynamics, and perceptions of sexuality.

Equipped with a miniature camera, the TRISAT-R CubeSat captured unique images of the Earth from 6,000 km, contributing to ESA’s research on medium-Earth orbit and digital imaging effects.

Partially shadowed Earth in the distance as seen from orbit at an altitude of 6,000 km (3,700 miles). This unusual image was obtained using a very small camera. It measures just 2 mm (0.08 inches), about the size of the end of a 20 euro cent (or US nickel). This is part of a small-scale technology experiment carried out on his shoebox-sized TRISAT-R CubeSat at ESA.

Iztok Kramberger, TRISAT-R project manager at the University of Maribor, explains: “This tiny camera, less than 2 cubic millimeters in size, captured images of an object of about 1 trillion cubic kilometers – our beautiful Earth – from thousands of kilometers away.”

A CubeSat made from three standardized 10 cm (4 inch) boxes, Trisat R This is Slovenia’s second space mission, with Europe’s first Vega-C launch last year reaching the relatively harsh environment of medium-Earth orbit at an altitude of 6,000 km (3,700 miles). The mission’s orbit passes through the core of the ionosphere (the electrically active layer of Earth’s atmosphere) and the inner Van Allen radiation belt.

The side cover size of TRISAT-R CubeSat is 10×10 cm. In the center you can see the photodiode (the white part in the middle) and the camera (the small black dot next to the diode and directly above the image). In the center of the camera, you can see a 2 x 2 mm camera lens with a 120 degree field of view. The lens is made from clear, radiation-resistant borosilicate glass and is attached directly to the image sensor below, providing 320 x 320 pixels.Credit: University of Maribor

This will enable TRISAT-R to test a range of radiation detection payloads. In addition, the TRISAT-R team mounted his two miniature cameras with lenses made of clear borosilicate glass directly onto a 320×320 pixel image sensor to provide limited radiation resistance. Ta.

Dr. Cranberger added: “These highly miniaturized cameras are not intended to perform ground imagery, so the resulting images of the Earth are very low resolution. Also, the TRISAT-R satellite uses magnetorque for attitude control. accurate pointing is difficult to achieve.

“Our main interest was in capturing an example of the ‘black sun effect’, which is common in terrestrial digital image processing, where pixel oversaturation can cause very bright areas to appear dark. We were successful in these investigations and were fortunate to be able to obtain images like this one. ”

ESA supported the manufacturing, assembly and testing of TRISAT-R through the ‘Fly’ element of the Integrated Support Technology Program, opening up on-orbit demonstration opportunities for European companies.

Located in a unique and challenging orbit, TRISAT-R’s commissioning phase is scheduled to conclude later this month, including 16 months of successful on-orbit operations.
