New ‘ear-EEG’ device could be used for early detection of neurodegenerative disorders

Posted by in categories: biotech/medical, engineering, life extension, neuroscience

A new project called Progression Assessment in Neurodegenerative Disorders of Aging or PANDA aims to detect subtle changes in a person’s sleep patterns that may indicate the onset of Alzheimer’s or Parkinson’s disease. The collaboration of this four-year project involves Rigshospitalet University, Denmark’s Aarhus University, and MedTech company T&W Engineering. The project has received funding of DKK 15 million to develop and test a small earbud-like experimental device that can detect the early signs of these diseases.

The Ear-EEG Technology

Unlike the traditional sleep-monitoring systems that require a person to stay in a clinic with multiple electrodes attached to their body, the ear-EEG allows for comfortable, long-term use at home. The device monitors electrical activity in the brain by measuring tiny voltage changes on the skin surface within the ear canal. It is also equipped with an oximeter for measuring blood oxygen levels, a microphone for monitoring respiration and heart rate, and a thermometer for measuring body temperature.

Japanese private space company to attempt historic Moon landing today

Posted by in category: space travel

Japan’s ispace could become the world’s first private company to perform a successful lunar landing.

Japan’s Hakuto-R lander, developed by private space firm ispace, will soon attempt a Moon landing. Last month, ispace announced that Hakuto-R successfully performed a lunar insertion maneuver. That was a crucial step ahead of its historic lunar landing attempt.

Molding of nanowires spurs unanticipated phases

Posted by in categories: engineering, nanotechnology, quantum physics

Sometimes to make big breakthroughs, you have to start very small.

One way that scientists can get the most out of certain is by fabricating that generate new properties at the material’s surfaces and edges. Cornell researchers used the relatively straightforward process of thermomechanical nanomolding to create single-crystalline nanowires that can enable metastable phases that would otherwise be difficult to achieve with conventional methods.

“We’re really interested in this synthesis method of nanomolding because it allows us to make many different kinds of materials into nanoscale quickly and easily, yet with some of the control that other nanomaterial synthesis methods lack, particularly control over the morphology and the size,” said Judy Cha, professor of materials science and engineering in Cornell Engineering, who led the project.

Clearest-ever picture of Mars’ moon Deimos

Posted by in category: space

As well as showing Deimos in more detail — including the first images of its far side — insights have been gained about its makeup and structure. The new observations challenge the longstanding theory that Mars’ moons are captured asteroids, and instead point to a planetary origin. In other words, both Deimos and Phobos likely came from Mars itself, possibly ejected from a large impact.


The science team behind the Emirates Mars Mission has revealed ground-breaking imagery and data that advances our understanding of Deimos.

Deimos is one of the two small moons of Mars, the other being Phobos. Discovered in 1,877, and named after the Ancient Greek god of terror, this rocky and irregularly shaped moon has a mean radius of 6.2 km (3.9 mi) and orbits at 23,500 km (6.9 Mars radii), making it the smaller and outermost natural satellite.

Astronomers explore multiple stellar populations in Messier 92

Posted by in categories: computing, space

Using the James Webb Space Telescope (JWST) and the Hubble Space Telescope (HST), astronomers from the University of Padua, Italy, and elsewhere have observed a metal-poor globular cluster known as Messier 92. The observations deliver crucial information regarding multiple stellar populations in this cluster. Results were published April 12 on the arXiv pre-print server.

Studies show that almost all (GCs) exhibit star-to-star abundance variations of light elements such as helium (He), oxygen (O), nitrogen (N), carbon © and calcium (Na). This indicates self-enrichment in GCs and suggests that are composed of at least two stellar populations.

Located some 26,700 away in the constellation of Hercules, Messier 92 (or M92 for short) is a GC with a metallicity of just-2.31 and a mass of about 200,000 . The cluster, estimated to be 11.5 billion years old, is known to host at least two stellar generations of stars—named 1G and 2G. Previous studies have found that Messier 92 has an extended 1G sequence, which hosts about 30.4% of cluster stars, and two distinct groups of 2G stars (2GA and 2GB).

GigaChat: Russia enters AI race with its ChatGPT rival

Posted by in category: robotics/AI

The AI is great at Russian but not so much in foreign languages.

Russia is the latest entrant to the artificial intelligence (AI) race as, mostly state-owned, Sberbank announced the launch of GigaChat, a rival to a conversational chatbot, ChatGPT. The move could heat the competition among countries looking to assume leadership positions in the technology that has taken the world by storm.

Last November, OpenAI launched ChatGPT, an AI model that can strike human-like conversations with its users. As more and more people began using ChatGPT, AI’s versatility became known.

Plastic used in food packaging found in brain two hours after ingestion

Posted by in categories: nanotechnology, neuroscience, particle physics

A study reflects on how these plastic particles can increase the risk of neuroinflammation and neurodegeneration.

We have known for a while that microplastics are in our bloodstreams, making their way into our bodies through daily consumables like milk and meat. The foreign presence of micro and nano-plastic particles (MNPs) in our bodies is dangerous for obvious reasons, and they can potentially reach remote locations and penetrate living cells.

In a scary confirmation of this potentiality, a new study has found that polystyrene, a widely-used plastic found in food packaging, could be detected in the brain just two hours after ingestion.

“Delivering drugs this way could offer less systemic toxicity and is more local, comfortable, and controllable,” said Canan Dagdeviren, an associate professor in MIT’s Media Lab and the senior author of the study, in a statement.
