The Internet of Things needs ultra-compact supercapacitors

Posted by in categories: energy, health, internet

Increased demand for super tiny electronic sensors coming from healthcare, environmental services and the Internet of Things is prompting a search for equally tiny ways to power these sensors. A review of the state of ultracompact supercapacitors, or “micro-supercapacitors,” concludes there is still a lot of research to be done before these devices can deliver on their promise.

The review appeared in the journal Nano Research Energy.

The explosion of demand in recent years for miniaturized , such as health monitors, environmental sensors and wireless communications technologies has in turn driven demand for components for those devices that have ever smaller size and weight, with lower energy consumption, and all of this at cheaper prices.

IoT Vulnerability Disclosures Up 57% in Six Months, Claroty Reveals

Posted by in categories: biotech/medical, internet, security

The number of vulnerability disclosures impacting extended internet of things (XIoT) devices increased by 57% in the first half of 2022 compared to the previous six months, according to a new report by Team82, the research team of cyber-physical systems (CPS) security firm Claroty.

The research also found that vendor self-disclosures increased by 69%. This would be a first for the industry, which usually relies more for disclosures on independent research teams. According to Team82, the trend indicates that more operational technology (OT), IoT, and internet of medical things (IoMT) vendors are establishing vulnerability disclosure programs and dedicating more resources to them.

Additionally, fully or partially remediated firmware vulnerabilities increased by 79% over the same time period, a significant improvement considering the relative challenges in patching firmware versus software vulnerabilities.

E-Project

“These results will have future implications in forensic medicine and genetic diagnosis.”

In 1999, François Brunelle, a Canadian artist, and photographer, began documenting look-alikes in a picture series “I’m not a look-alike!”

The project, undoubtedly, was a massive hit on social media and other parts of the internet, but it also drew the attention of scientists who study genetic relationships.

The Stream of Consciousness and Personal Identity

Posted by in categories: biotech/medical, internet, neuroscience

Lastly, there is the concern that this is all whimsically unimportant, or worse, an obtuse disregard for more prosaic societal concerns. Some people may find debates of this sort to be pedantic and even snobbish, given the justified concern that advanced futuristic technologies are likely to benefit wealthy elites long before they trickle down to the masses. Worse, some people may expect that such technologies are likely impossible and that such metaphysical navelgazing is an ivory tower distraction in a world of real problems and challenges. To that reaction I say the importance is not necessarily in determining the prospects of technological and medical marvels that reside far in the future, if ever. The more relevant issue, and the reason I have committed so much of my life to contemplating and writing about these questions, is that we profoundly desire the most accurate model possible of reality and understanding of the human condition. Ultimately, we want to understand ourselves as conscious beings in the universe and to understand the nature of our existence. That is the real issue here, at least for me.

Faster fish tracking through the cloud

Posted by in categories: energy, internet, sustainability

The fastest way to track a fish is to use the cloud, figuratively speaking. A new acoustic receiver, developed by researchers at Pacific Northwest National Laboratory (PNNL) and published in the IEEE Internet of Things Journal, sends near-real-time fish tracking data to the digital cloud, providing timely information to dam operators and decision-makers about when, where, and how many fish are expected to pass through dams. Instead of relying on seasonal estimates of fish migration from previous years, these data from tagged fish support more informed decisions about dam operations that affect fish passage.

“This receiver provides up-to-the-hour data to dam operators to assist in making informed day-to-day decisions in support of passage, like adjusting water flow when it’s clear that a large group of juvenile fish are approaching the dam,” said Jayson Martinez, a PNNL mechanical engineer who co-developed the receiver.

Hydropower dams are an important source of dependable renewable energy, generating about six percent of total electricity in the United States. Helping fish navigate them safely is a key part of reducing dams’ environmental impact. The new receiver is a critical piece of the puzzle in the ongoing endeavor to improve fish passage.

China’s new radio telescope will have dangerous solar eruptions in its gaze

Posted by in categories: internet, space

It’s part of a wider project aimed at investigating dangerous solar eruptions.

China is building the world’s largest array of telescopes designed to study the Sun, a report from the South China Morning Post.

The array, called the Daocheng Solar Radio Telescope (DSRT), will help scientists better understand coronal mass ejections — massive solar eruptions that have the potential to knock out the world’s internet and disrupt global satellite services.

SpaceX tweaks Starlink Gen2 plans to add Falcon 9 launch option

Posted by in categories: internet, satellites

SpaceX says it has revised plans for its next-generation Starlink Gen2 constellation to allow the upgraded satellites to launch on its workhorse Falcon 9 rocket in addition to Starship, a new and unproven vehicle.

Set to be the largest and most powerful rocket ever flown when it eventually debuts, SpaceX’s two-stage Starship launch vehicle is also intended to be fully reusable, theoretically slashing the cost of launching payloads into and beyond Earth orbit. Most importantly, SpaceX says that even in its fully-reusable configuration, Starship should be capable of launching up to 150 tons (~330,000 lb) to low Earth orbit (LEO) – nearly a magnitude more than Falcon 9. However, once said to be on track to debut as early as mid-2021 to early 2022, it’s no longer clear if Starship will be ready for regular Starlink launches anytime soon.

In August 2021, SpaceX failed a major Starlink Gen2 revision with the FCC that started the company along the path that led to now. That revision revealed plans to dramatically increase the size and capabilities of each Gen2 satellite, boosting their maximum throughput from about 50 gigabits per second (Gbps) to ~150 Gbps. Just as importantly, SpaceX’s August 2021 modification made it clear that the company would prefer to launch the entire constellation with Starship, although it included an alternative constellation design that would lend itself better to Falcon 9 launches.

SpaceX: Why Starlink has some astronomers worried

Posted by in categories: internet, satellites

The new generation of Starlink satellites remains above the accepted brightness threshold.


Unlike the nascent Iridium constellation — which really only found niche applications — Starlink is already proving its worth. For example, Starlink is currently keeping the Internet on in Ukraine during the ongoing Russian invasion.

The main concern in professional astronomy is the impact on current and upcoming all-sky surveys, such as the Vera C. Rubin telescope. This survey will scour the sky nightly down to a faint +22nd magnitude. A recent article in Nature notes that the 1.5-meter Zwicky Transient Facility (ZTF) telescope at Palomar sees Starlink streaks on 18 percent of its deep-sky images. A recent International Astronomical Union statement called for operational Starlinks to fall below +7th magnitude.
