Forget about evolution, climate change or vaccines – what makes people really lose their mind, apparently, is cats.

“We’ve had posts that have affected people’s lives in a very substantial way, including posts that went beyond the virtual world. People really got threats or disrespectful comments,” says Yomiran Nissan.

Upon removal of ventilator support, two of the patients showed an increase in heart rate along with a surge of gamma wave activity, considered the fastest brain activity and associated with consciousness.

Furthermore, the activity was detected in the so-called hot zone of neural correlates of consciousness in the brain, the junction between the temporal, parietal and occipital lobes in the back of the brain. This area has been correlated with dreaming, visual hallucinations in epilepsy, and altered states of consciousness in other brain studies.

The U.S. Department of Defense (DOD) invented a wearable during the pandemic that was extremely adept at identifying infections.

This is according to a press release by the department published on Thursday.

Now the organization is ready to take the next steps in what it calls the Rapid Assessment of Threat Exposure project, also known as the RATE program.

The research uses the genomes of 241 species.

A species is a group of living organisms that share a set of common characteristics and are able to breed and produce fertile offspring. The concept of a species is important in biology as it is used to classify and organize the diversity of life. There are different ways to define a species, but the most widely accepted one is the biological species concept, which defines a species as a group of organisms that can interbreed and produce viable offspring in nature. This definition is widely used in evolutionary biology and ecology to identify and classify living organisms.

Technophobia is an extreme fear of technology. People with technophobia may fear the power of artificial intelligence, robots or computers.

Technophobia is more than resistance to learning new technology. Rather, people with the condition may obsess over technology. Or, they may go to great lengths to avoid incorporating technology into their lives.

Technophobia is not a clinical diagnosis in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Still, as technology has expanded rapidly in recent years, some clinicians treat technophobia like a specific phobia. Specific phobias are irrational fears of a particular situation, object, animal or interaction. The fear isn’t in proportion to the actual danger.

Gravitational wave astronomy is still in its early stages. So far it has focused on the most energetic and distinct sources of gravitational waves, such as the cataclysmic mergers of black holes and neutron stars. But that will change as our gravitational telescopes improve, and it will allow astronomers to explore the Universe in ways previously impossible.

Although gravitational waves have many similarities to light waves, one distinct difference is that most objects are transparent to gravitational waves. Light can be absorbed, scattered, and blocked by matter, but gravitational waves mostly just pass through matter. They can be lensed by the mass of an object, but not fully blocked.

This means that gravitational waves could be used as a tool to peer inside astronomical bodies, similar to the way X-rays or MRIs allow us to see inside a human’s body.

Is mind reading possible? An age-old question with multiple unproven answers. Those who study psychology often claim that they can understand what the other person is saying as they study mental processes, brain functions, and behaviour, but even they can be 100 per cent accurate.

A study, published in the journal Nature Neuroscience, attempts to address it as scientists have said that they have come up with a way to decode a stream of words in the brain using MRI scans and artificial intelligence.

The study titled — “Semantic reconstruction of continuous language from non-invasive brain recordings” — noted that the system won’t replicate each word but it reconstructs the brief of what a person hears or imagines. The study was published in the journal Nature Neuroscience.

UNSW Sydney researchers have developed a chip-scale method using OLEDs to image magnetic fields, potentially transforming smartphones into portable quantum sensors. The technique is more scalable and doesn’t require laser input, making the device smaller and mass-producible. The technology could be used in remote medical diagnostics and material defect identification.

Smartphones could one day become portable quantum sensors thanks to a new chip-scale approach that uses organic light-emitting diodes (OLEDs) to image magnetic fields.

Researchers from the ARC Centre of Excellence in Exciton Science at UNSW Sydney have demonstrated that OLEDs, a type of semiconductor material commonly found in flat-screen televisions, smartphone screens, and other digital displays, can be used to map magnetic fields using magnetic resonance.

Scientists are still determining whether humans will reach a maximum possible age or if we can extend lifespan indefinitely. One thing we know is that the aging we see and feel in our bodies is connected to aging that individual cells experience. Yeast is a common model in molecular biology that is often used to study aging. In 2020, scientists found that yeast cells could go down one of two aging paths; in one, structures called nucleoli were degraded and ribosomal DNA experienced less silencing; in the other, mitochondria were affected and heme accumulation was reduced. The researchers suggested that these were two distinct types of terminal aging.

In follow-up work, the research team has manipulated the genetics of those pathways, and have extended the lifespan of cells by doing so. The work has been reported in Science. The investigators applied a solution to the cells that altered gene circuits to stop the cells from deteriorating.
