Researchers at Nagoya University in Japan have developed gallium-doped zinc oxide (GZO) nanosheets that may enhance camera resolution in compact devices, including smartphones and medical endoscopes.
These nanosheets enable a single pixel to detect the intensity of red, green and blue (RGB) light while remaining nearly transparent, unlike conventional sensors. They are ultrathin, lightweight and can withstand temperatures up to 400°C (752°F), making them suitable for extreme environments such as space hardware and automotive systems.
The findings were published in the journal ACS Nano.
Most contemporary portable electronics, including laptops, smartphones and smart watches, are powered by batteries that need to be recharged daily or every few days. Over the past decade, however, some engineers have been exploring the possibility of developing battery-free electronic devices that autonomously derive electricity from renewable sources, such as sunlight, indoor lighting or heat.
A research team at Penn State University recently developed a compact integrated circuit (IC) that harvests energy solely from ambient light, using this energy to run computations and sense chemicals in its surroundings. This new chip, introduced in a paper published in Nature Electronics, could enable the development of devices that never require charging and thus continue working uninterrupted even in environments where replacement batteries and electrical sockets are not available.
“This work grew out of a broader question we have been asking in my group: Can we build electronic systems that do not simply sense information, but also process that information locally and power themselves from their environment?” Saptarshi Das, senior author of the paper, told Tech Xplore. “Many future Internet of Things (IoT) and edge-computing systems will need to operate in remote or hard-to-access locations, where replacing batteries is impractical. We wanted to demonstrate a compact, fully integrated chip that combines energy harvesting, sensing and computation in a single monolithic three-dimensional architecture.”
On Sunday, July 5, 2026, at 1 p.m. U.S. Pacific Time, watch a compilation stream of four additional presentations from the May 2–3, 2026, sessions at the University of California, Berkeley Conference on Aging and Longevity (BerkeleyCAL), hosted by Professor Steven A. Garan, Director of Bioinformatics at the Center for Research and Education on Aging.
These presentations focus key insights in geroscience, both from its history and in regard to promising future directions and some implications for effective advocacy; they are delivered by some of the leading researchers in longevity science – Aubrey de Grey, Brendan Hughes, Felipe Sierra, and Michael West. Three of the presentations include question-and-answer sessions.
Dr. Aubrey de Grey of the Longevity Escape Velocity Foundation (LEVF) discusses the historical approaches to viewing aging and their shortcomings, as well as the damage-repair approach that he has championed and its prospects for rejuvenating the body. He also discusses implications for advocacy and which tactics could be more effective in bringing the public on board. Note: This presentation is an excerpt, captured by USTP Chairman Stolyarov on his phone camera. It is being made available due to the official recording having been lost.
Dr. Brendan Hughes from the Buck Institute discusses his thesis research on how DNA damage shapes unique, disease-relevant senescent cell states in neurons and other brain cell types. He details a methodology involving the direct differentiation of fibroblasts into neurons and oligodendrocytes to better understand aging-related cellular responses and potential therapeutic targets for Alzheimer’s disease. Dr. Hughes also highlights the importance of basic research in developing future interventions, such as senescence-targeted therapies or DNA repair modulations. The question-and-answer session includes a question from USTP Chairman Stolyarov to Dr. Hughes.
Dr. Felipe Sierra advocates for a shift in geroscience from solely targeting age-related diseases to focusing on maintaining intrinsic health and functional capacity. He proposes that molecular resilience acts as the crucial link between aging biology and long-term health, suggesting that strengthening this resilience could prevent the onset of multiple morbidities. Ultimately, he calls for more robust longitudinal studies and clinical trials that prioritize health-span metrics over the traditional, disease-centered approach to geriatric medicine.
Dr. Michael West explores the biological dichotomy between mortal somatic cells and the immortal germline to explain the fundamental mechanisms of aging and cellular regeneration. He discusses the history of stem-cell research and his work on telomeres and nuclear transfer, which demonstrated that developmental aging and cellular differentiation are reversible processes. Dr. West proposes a new approach to regenerative medicine that focuses on unlocking the body’s innate potential by targeting heterochrony genes to combat chronic degenerative diseases.
A joint operation involving Google has disrupted NetNut, a residential proxy network that gave access to millions of compromised Android devices, including smart TVs and streaming boxes.
Also known as Popa, the NetNut botnet allowed cybercriminals and espionage groups to hide behind legitimate home internet addresses when launching attacks.
According to the Google Threat Intelligence Group (GTIG), the residential proxy botnet is estimated to comprise at least two million compromised devices.
Imagine opening a difficult book in a quiet room. The first page is dense. You read one paragraph, then reread it. Nothing “clicks” yet. Your brain is doing what learning often requires: spending effort before the reward arrives. Then your phone lights up. One thumb movement, and the situation changes completely. A joke, a message, a clip, a tiny social reward: all available instantly, all requiring almost no effort. The book has not become harder and, definitely, your intelligence has not disappeared. But the book now feels more expensive, because another activity nearby offers a much better bargain: reward now, effort almost zero.
That is the central idea of the paper “An Effort Recalibration Framework for Digital Media Use and Cognition” that just appeared in Nature Human Behavior. It argues that the most important effect of social media might be that repeated exposure to effortless digital rewards changes how we value effort itself. Over time, the authors suggest, digital media may recalibrate our internal sense of what effort is worth. Difficult work then begins to feel less attractive, not because we can no longer do it, but because our everyday decision system has learned to expect faster returns.
14 years ago, Steve Mann told me that technology that masters nature is not sustainable.
At the time, that sounded like the poetic caution of a man the media had nicknamed “the cyborg Luddite.” Today it reads like a weather report.
Steve is the person the IEEE named the father of wearable computing. He built the EyeTap decades before Google Glass, invented HDR imaging now sitting in the phone in your pocket, and was called the world’s first cyborg. So when he argues for using less, for choosing which technologies to embrace and which to walk away from, he is not speaking from fear of the machine. He is speaking from a deeper intimacy with it than almost anyone alive.
His core move was to refuse the framing everyone else accepted.
Not more technology. Not less technology. Appropriate technology. Balanced with nature instead of replacing it.
And here is the line that has aged into something close to prophecy:

Open any device built in the past five years, look inside its memory subsystem, and the chips you find were almost certainly fabricated in one of three South Korean industrial cities — Hwaseong, Pyeongtaek, or Icheon — by one of two companies whose combined market capitalisation now exceeds $700 billion. The historical improbability of this situation is not a matter of degree but of category. Korea in 1953 did not have a semiconductor industry, a precision manufacturing tradition, an advanced engineering workforce, or the kind of capital markets that could finance industrial development. It had a per-capita income lower than essentially every other country whose subsequent economic trajectory has been studied by development economists, a primarily agricultural economy substantially destroyed by three years of active warfare, and a small population (~20 million) whose adult literacy rate stood at approximately 20 percent. The proposition that, 72 years later, two companies headquartered in the same country would manufacture the memory chips inside Apple’s iPhones, Google’s Pixel devices, Microsoft’s data centres, Nvidia’s AI accelerators, Tesla’s autonomous-driving computers, and essentially every other major piece of digital hardware sold globally — would have been considered, by any reasonable observer in 1953, structurally impossible.
WASHINGTON — Rocket Lab is acquiring satellite telecommunications company Iridium for $8 billion as part of its effort to become an end-to-end space company.
The companies announced an agreement June 29 under which Rocket Lab will acquire Iridium for $54 a share in cash and stock, valuing Iridium at $8 billion. That is a 24% premium over the closing price of Iridium’s shares June 26. The deal is projected to close in mid-2027 pending regulatory and other approvals.
