Oh yea? I just learned the steps to copperhead road so… whatever.


Light is something in our world that we are very familiar with, and yet it can still throw some incredible curveballs when you look at it in detail. A newly discovered one comes from a pretty well-established phenomenon: what happens when light passes through an interface? That could be glass, water, or something completely different. The solution for that has long been established, but scientists have now found something weird going on in the middle.

As light goes through an interface, its speed changes. The solution for the behavior of light on one side of the interface or the other is the well-established standard wave equation. They can be linked with no problem (a piecewise continuous solution) but this still doesn’t explain what happens at the interface itself. There, the wave should experience an acceleration that is not accounted for by the current solution.

Now, an equation has been put forward in the case of a universe with one space dimension and one time dimension.

The rise in capabilities of artificial intelligence (AI) systems has led to the view that these systems might soon be conscious. However, we might be underestimating the neurobiological mechanisms underlying human consciousness.

Modern AI systems are capable of many amazing behaviors. For instance, when one uses systems like ChatGPT, the responses are (sometimes) quite human-like and intelligent. When we, humans, are interacting with ChatGPT, we consciously perceive the text the model generates, just as you are currently consciously perceiving this text here.

The question is whether the language model also perceives our text when we prompt it. Or is it just a zombie, working based on clever pattern-matching algorithms? Based on the text it generates, it is easy to be swayed that the system might be conscious.

Researchers with the Translational Research in Neuroimaging and Data Science (TReNDs) Center at Georgia State have identified important new methods for accurately identifying possible biomarkers in adolescent brains that can reliably predict cognitive developments and psychiatric issues.

A new study, published in Nature Mental Health, represents the first large-scale analysis of its kind in which researchers analyzed functional network connectivity (FNC) across scans and identified associations with a diverse range of health measures in children. Researchers believe that inferences about early cognitive and psychiatric behaviors in children may be made using these intra-subject variabilities as a useful biomarker.

Researchers studied four scans from more than 9,000 subjects ages 9 to 11.

The widespread use of electronic devices to interact with others and access the internet has increased the need for highly performing communication technologies that can transmit data faster and more efficiently. Increasing the data transmission rate of devices without adversely impacting their energy efficiency, however, is a challenging task.

Researchers at University of Southampton in the UK recently developed a promising new based on complementary metal-oxide-semiconductor (CMOS) technology and . This transmitter, introduced in Nature Electronics, was found to achieve remarkable data transmission rates while consuming minimal energy.

“The integration of silicon photonics with electronics is essential for producing practical systems for numerous applications,” David J. Thomson, one of the authors of the paper, told Tech Xplore.

El Niño-Southern Oscillation (ENSO) is a climate phenomenon occurring every 2–7 years in the tropical Pacific Ocean, associated with changes in air pressure east to west.

During El Niño events equatorial blowing west weaken, causing changes in air pressure and that move warm surface water eastward from the western Pacific to coastal South America. This results in a deeper thermocline (the depth at which rapidly changes) that prevents the normal upwelling of cooler, nutrient-rich waters, having devastating impacts on marine food chains, as well as local communities reliant upon the fishing industry.

It also brings heavier and prolonged rainfall to South America, increasing the threat of flooding, while in Australia and Indonesia there is drought, posing hazards for water supply and irrigation for agriculture. During La Niña events, all off these conditions reverse.

Researchers have developed a virtual reality application where a range of 3D modeling tools can be opened and controlled using just the movement of a user’s hand.

The researchers, from the University of Cambridge, used machine learning to develop ‘HotGestures’—analogous to the hot keys used in many desktop applications.

HotGestures give users the ability to build figures and shapes in without ever having to interact with a menu, helping them stay focused on a task without breaking their train of thought.

Nuclear arms are the most destructive, indiscriminate and monstrous weapons ever produced – but today, we can all celebrate a major milestone in the long march towards peace: the Treaty on the Prohibition of Nuclear Weapons (TPNW) is now part of international law!

The year 2021 also marks the 50th anniversary of Greenpeace, which began life in September 1971 when a small group of activists set sail to the island of Amchitka, off the west coast of Alaska, to try and stop nuclear weapons testing from taking place. Greenpeace could not be more delighted that in the anniversary year of our founding journey, we can join the celebration to mark this historic Treaty coming into force and pay our deepest respects to advocates for this momentous achievement, led by the International Campaign to Abolish Nuclear Weapons (ICAN).

Greenpeace France interviewed Jean-Marie Collin of ICAN France about the challenges and prospects that arise from the Treaty’s entry into force.
