It’s notoriously difficult for doctors to identify a wound that is becoming infected. Clinical signs and symptoms are imprecise and methods of identifying bacteria can be time-consuming and inaccessible, so a diagnosis can be subjective and dependent on clinician experience. But infection can stall healing or spread into the body if it isn’t treated quickly, putting a patient’s health in grave danger. An international team of scientists and clinicians thinks they have the solution: a device run from a smartphone or tablet app, which allows advanced imaging of a wound to identify infection.

“Wound care is one of today’s most expensive and overlooked threats to patients and our overall health care system,” said Robert Fraser of Western University and Swift Medical Inc., corresponding author of the study published in Frontiers in Medicine. “Clinicians need better tools and data to best serve their patients who are unnecessarily suffering.”

The scientists developed a device called the Swift Ray 1, which can be attached to a smartphone and connected to the Swift Skin and Wound software. This can take medical-grade photographs, infrared thermography images (which measure body heat), and bacterial fluorescence images (which reveal bacteria using violet light).

The team used acupuncture needles to deliver the trigger for 10 seconds a day, and the blood sugar levels in the mice returned to normal within a month. The rodents even regained the ability to manage blood sugar levels after a large meal without the need for external insulin, a normally difficult feat.

Called “electrogenetics,” these interfaces are still in their infancy. But the team is especially excited for their potential in wearables to directly guide therapeutics for metabolic and potentially other disorders. Because the setup requires very little power, three AA batteries could trigger a daily insulin shot for more than five years, they said.

The study is the latest to connect the body’s analogue controls—gene expression—with digital and programmable software such as smartphone apps. The system is “a leap forward, representing the missing link that will enable wearables to control genes in the not-so-distant future,” said the team.

Metal oxide’s properties could enable a wide range of terahertz frequency photonics.

Visible light is a mere fraction of the electromagnetic spectrum, and the manipulation of light waves at frequencies beyond human vision has enabled such technologies as cell phones and CT scans.

Rice University researchers have a plan for leveraging a previously unused portion of the spectrum.

Smartphones and other tech pose special challenges — and opportunities — for young brains.

It hasn’t all been good though. We are incredibly dependent on our devices — smartphone addiction is a growing concern. A staggering 81 percent of Americans own smartphones. This is a huge increase from the Pew Research Center’s first survey of smartphone ownership conducted in 2011 when just 35 percent owned them.

With the rise of artificial intelligence technology, many experts raised their concerns regarding the emissions of warehouses full of the computers needed to power these AI systems. IBM’s new “brain-like” chip prototype could make artificial intelligence more energy efficient, since its efficiency, according to the company, comes from components that work in a similar way to connections in human brains.

Thanos Vasilopoulos, a scientist at IBM’s research lab spoke to BBC News, saying that compared to traditional computers, “the human brain is able to achieve remarkable performance while consuming little power.” This superior energy efficiency would mean large and more complex workloads could be executed in low-power or battery-constrained environments like cars, mobile phones, and cameras. “Additionally, cloud providers will be able to use these chips to reduce energy costs and their carbon footprint,” he added.

Further boosting this ethos of accessibility is the fact that Hestia will be compatible with both iOS and Android phones. Dupuy pointed out that even a smartphone that is around five years old will work with Hestia for taking images of the sun and the moon, but to see more deep field objects like nebulas, a more recent and more sensitive smartphone such as an iPhone 12 or 13 may be required.

Vaonis, launched in 2016, is no stranger to introducing astronomy equipment via a Kickstarter campaign. In 2020 they successfully launched the Vespera smart telescope after a fund-raising program. The difference between Hestia and previous projects is this smartphone telescope project is much more affordable.

“It was possible to better in terms of price,” Dupuy said. “We wanted to use all the image processing experience we have gained to develop an app and to create a very affordable new product.”

Chromium compounds could soon replace the rare and expensive metals osmium and ruthenium.

Scientists have found a way to make solar panels and phone screens from readily available chromium. This is according to a report.

The article highlights how a major breakthrough sees material “almost as rare as gold” replaced by everyday components, significantly reducing “the price of manufacturing the technology that relies on it.”
