Trying to spot contraband is a tricky business. Not only is identifying items like narcotics and counterfeit merchandise difficult, but the current most used technology—X-rays—only gives a 2D view, and often a muddy one at that.

“It’s not like X-raying a tooth, where you just have a tooth,” said Eric Miller, professor of electrical and computer engineering at Tufts. Instead, it’s like X-raying a tooth and getting the entire dental exam room.

But Miller and his research team have now found a possible solution that uses AI with to spot items that shouldn’t be there and is accurate 98% of the time. Their findings were published in Engineering Applications of Artificial Intelligence.

The human working memory (WM) is the cognitive system responsible for the temporary storage and processing of information vital to task completion. In contrast, human long-term memory (LTM) is the system that holds information for prolonged periods of time, organizing acquired knowledge into distinct categories, such as facts, events, skills and habits.

For decades, most psychologists and neuroscientists have viewed these two memory components as separate systems, one tackling short-term and the other long-term tasks, supported by distinct neural processes. Therefore, most studies conducted so far have focused on only one of these systems, instead of exploring the potential connections between working memory and long-term memory processes.

Researchers at the Cedars-Sinai Medical Center and other institutes recently set out to simultaneously investigate the neural underpinnings of both WM and LTM, to determine whether these systems utilize some common mechanisms to store information. Their findings, published in Neuron, suggest that the two systems interact in the hippocampus, with persistent WM activity predicting the formation of LTM.

Researchers are starting to find patterns in how we sleep that could point to early signs of dementia or Parkinson’s disease.

There are some obvious signs that your loved one could be showing early signs of dementia, which affects almost seven million people in the US.

The common signs include being unable to learn new tasks, struggling to stay focussed, finding it hard to contribute in conversations, mistaking things for other objects and/or getting unusually emotional or afraid.

The Moon still holds mysteries that leave scientists in awe. A massive, heat-radiating object beneath its surface has sparked new questions about its origins.

This discovery offers a glimpse into the Moon’s hidden history, challenging what we thought we knew about our celestial neighbor.

Saber teeth – the long, sharp, blade-like canines found in extinct predators such as Smilodon – represent one of the most extreme dental adaptations in nature.

They evolved at least five times throughout mammalian history and are a classic example of convergence, which is when similar structures evolve independently in unrelated animal groups.

With no living representatives, scientists have long debated how these predators used their fearsome teeth, and why this extreme tooth shape evolved so often.

Subtle activation of a small subset of neurons in one region of the brain can make male mice resilient to, and even reverse, the detrimental effects of chronic stress. The same is true for female mice, but in a totally different region of the brain.

Researchers at Penn State reported these findings in two studies published in the journal Molecular Psychiatry and said the results could help explain the efficacy, or lack thereof, of certain antidepressant drugs and inform the development of new drugs and therapies.

The team developed a protocol to continuously activate neurons that produce the signaling molecule somatostatin, which helps regulate several biological processes, in specific brain regions in mice. The researchers found that doing so in a region of the brain called the prelimbic cortex made male mice resilient to stress, but failed to do so in female mice.

RNA is the molecule that reads the genetic information stored in DNA. It’s critical for the proper functioning of cells, and in a new study published in Nature Communications, University of California, Irvine scientists have discovered a way of tagging RNA with a glowing bioluminescent molecule that allows them to track RNA in real time as it moves throughout the body. The work promises to help scientists better understand everything from the way viruses propagate to how memories form in the brain.

In a study that could help scientists better understand and manipulate cell division, RIKEN biologists have engineered artificial structures that replicate one of life’s most crucial processes—the precise division of packages of DNA known as chromosomes.

When a cell starts splitting into two , its align. The process of chromosome alignment can be likened to a high-stakes game of tug-of-war.

In a healthy cell, chromosomes line up at the center, each pulled by fibers extending from opposite sides of the cell. These fibers attach to kinetochores—anchors that ensure chromosomes are evenly pulled apart during —at the center of the dividing structures.

An international research team led by the University of California, Irvine has discovered a new type of skeletal tissue that offers great potential for advancing regenerative medicine and tissue engineering.

Most cartilage relies on an external extracellular matrix for strength, but “lipocartilage,” which is found in the ears, nose and throat of mammals, is uniquely packed with fat-filled cells called “lipochondrocytes” that provide super-stable internal support, enabling the tissue to remain soft and springy—similar to bubbled packaging material.

The study, published in the journal Science, describes how lipocartilage cells create and maintain their own lipid reservoirs, remaining constant in size. Unlike ordinary adipocyte fat cells, lipochondrocytes never shrink or expand in response to food availability.
