The hippocampus is a region of the brain known to the associated with memory, learning, spatial navigation and emotion. In 1971, neuroscientists discovered that the hippocampus influences spatial navigation through the formation of a series of “spatial codes,” which encode characteristics related to an animal or human’s surrounding environment, including sensory cues and where rewards are located.

These codes are encoded by a type of neurons known as “place cells,” which were found to become active when an animal is entering a specific place or location in its environment. Together, place cells in the hippocampus form representations of the places that animals are navigating, also known as cognitive maps.

Since place cells were first uncovered, numerous teams worldwide have been conducting studies aimed at better understanding their function and how they encode spatial information. While there is now a large body of research focusing on place cells, some of the factors influencing their functioning are still poorly understood.

Intentionally preventing the retrieval of an unwanted memory hinders future attempts to reactivate the memory’s neural representation and causes a reduction in the vividness with which it can be recalled.

Anyone waiting for a sociopath to grow up or calm down should give up; they will not change, a new study has revealed.

The research, published in the International Journal of Offender Therapy and Comparative Criminology, surveyed more than 1,200 partners, family members and friends of psychopaths—93% reported they were just as bad, or worse, as they got older.

Co-author Professor Martin Sellbom, of the University of Otago’s Department of Psychology, says the research focused on people with antisocial personality disorder/psychopathy who were aged over 50.

During a high-level talk on NASA’s objectives for human space exploration, we got an early glimpse of what a 30 day crewed mission to the surface of Mars could eventually look like.

It’s an exciting prospect that, while many years if not decades away, shows the agency’s commitment to fulfilling humanity’s dreams of setting foot on the Red Planet for the first time in history.

NASA director of space architectures Kurt “Spuds” Vogel outlined what such a mission could entail. The agency is envisioning a habitat spacecraft to make the months long journey there, which uses a hybrid rocket stage that combines chemical and electric propulsion.

We should really be looking to nuclear power FAR more than we have been. Until fusion finally comes of age anyway. It’s one of the most annoyingly counterproductive issue with many environmentalists I tend to have.

Extreme temperatures and ongoing drought could cause the power grid to buckle across vast areas of the country this summer, potentially leading to electricity shortages and blackouts, a US power grid regulator said Wednesday.

NERC, a regulating authority that oversees the health of the nation’s electrical infrastructure, says in its 2022 Summer Reliability Assessment that extreme temperatures and ongoing drought could cause the power grid to buckle. High temperatures, the agency warns, will cause the demand for electricity to rise. Meanwhile, drought conditions will lower the amount of power available to meet that demand.

The therapy, which the researchers hope to trial in humans, harnesses ‘dancing molecules’ to communicate with the body’s cells.

A Massachusetts resident has tested positive for monkeypox, health officials confirmed Wednesday, making it the first case of the rare virus detected in the United States this year.

According to a release from the Massachusetts Department of Public Health, the patient is an adult male who recently traveled to Canada. The department completed initial testing Tuesday and was confirmed by the Centers for Disease Control and Prevention.

“The case poses no risk to the public, and the individual is hospitalized and in good condition,” MDPH stated in a press release. “DPH is working closely with the CDC, relevant local boards of health, and the patient’s health care providers to identify individuals who may have been in contact with the patient while he was infectious.”
