Microscopic magnetic nanodiscs could provide a much less invasive means of providing deep brain stimulation, a new study says.

Recently, two independent research groups have shown that the brain codes for zero much as it does for other numbers, on a mental number line. But, one of the studies found, zero also holds a special status in the brain.

In recent years, research started to uncover how the human brain represents numbers, but no one examined how it handles zero. Now two independent studies, led by Nieder and Barnett, respectively, have shown that the brain codes for zero much as it does for other numbers, on a mental number line. But, one of the studies found, zero also holds a special status in the brain.

“The fact that [zero] represents nothing is a contradiction in itself,” said Carlo Semenza, a professor emeritus of neuroscience at the University of Padua in Italy who wasn’t involved in either study. “It looks like it is concrete because people put it on the number line — but then it doesn’t exist. … That is fascinating, absolutely fascinating.”

Actin, a family of proteins that help give cells their shape, are abundant throughout the body.

Humans aren’t the only ones who grow forgetful as they age—fruit flies do, too. But because fruit flies have a lifespan of only about two months, they can be a useful model for understanding the cognitive decline that comes with aging.

A new study published in Nature Communications shows that when a common cell structural protein called filamentous actin, or F-actin, builds up in the brain, it inhibits a key process that removes unnecessary or dysfunctional components within cells, including DNA, lipids, proteins and organelles.

Can water be harvested from the air to help mitigate water scarcity across the globe? This is what a recent study published in Technologies hopes to address as a team of researchers from The Ohio State University have developed a novel device that can provide faster and more efficient methods for harvesting water from the air compared to longstanding devices, also called atmospheric water harvesting (AWH). This study holds the potential to help regions around the world mitigate the need for access to clean drinking water, as approximately 2 billion people suffer from lack of clean drinking water in their respective regions.

“You can survive three minutes without air, three weeks without food, but only three days without water,” said Dr. John LaRocco, who is a research scientist in the Department of Psychiatry and Behavioral Sciences at The Ohio State University and lead author of the study. “But with it, you can begin to solve a lot of problems, like national security, mental health or sanitation, just by improving the accessibility of clean drinking water.”

For the device, the researchers designed a nickel titanium-based dehumidifier with temperature-sensitive materials, resulting in harvesting greater amounts of water at 0.18 milliliters per watts per hour compared to 0.16 milliliters per watts per hour for traditional harvesters after 30 minutes. Additionally, the temperature-sensitive materials help regulate the amount of heat used during the harvesting process, resulting in approximately half the power needed to use the harvester. Finally, the reduced size of the harvester provides mobility to be used anywhere in the world, whereas traditional harvesters tend to be large and require significant amounts of energy to operate.

A paralysed man who had an extreme form of locked-in syndrome and heard a nurse say he was “brain dead” has become the first ever to recover after hearing medical professionals debating whether or not to switch off his life support.

In 2017, Jacob Haendel was living a normal life as a head chef in Boston, Massachusetts but in the space of a few weeks, his life was turned upside down after he was diagnosed with acute toxic progressive leukoencephalopathy, which progressed into locked-in syndrome and forced his body would slowly shut down. An extreme form of locked-in syndrome is a condition where a patient is aware but cannot move or communicate verbally due to complete paralysis and can be caused by brain trauma, infection or exposure to toxins.

A sensitive perception of the environment is crucial for guiding our behavior. However, an overly sensitive response of the brain’s neural circuits to stimuli can lead to neurodevelopmental disorders such as epilepsy. University of Basel researchers report in the journal Nature how neuronal networks in the mouse brain are fine-tuned.

One of the characteristics of depression is a tendency to perceive sensory stimuli and everyday situations in an excessively negative way. But the mechanisms underpinning this “negativity bias,” which can fuel the development of depressive symptoms, had previously remained largely unknown.
