Naked mole rats, frogs and other animals may hold the secrets to preventing brain injury

Some animals use microRNA to protect the brain from various stressors. Understanding how they do this and applying it to humans has potential for revolutionary treatments.
New research indicates that rhesus monkeys show interoception – the ability to sense physiological processes like their own heartbeats. Matthew Verdolivo/UC Davis IET Academic Technology Services

Monkeys can sense their own heartbeats, an ability tied to mental health, consciousness and memory in humans

Researchers used a test designed for babies to show that rhesus monkeys can sense their own heartbeats. The finding opens up important paths of research into consciousness and mental health issues.

Brains are bad at big numbers, making it impossible to grasp what a million COVID-19 deaths really means

The brain can count small numbers or compare large ones. But it struggles to understand the value of a single large number. This fact may be influencing how people react to numbers about the pandemic.

Restoring touch through electrodes implanted in the human brain will require engineering around a sensory lag

When designing neuroprosthetic devices for users to control with their thoughts, engineers must take into account the sensory information brains collect from the environment and how it gets processed.

Even mild cases of COVID-19 can leave a mark on the brain, such as reductions in gray matter – a neuroscientist explains emerging research

New research offers insights into the brain after COVID-19 that may have implications for our understanding of long COVID-19 and how the disease affects our senses of taste and smell.

How recess helps students learn

The physical activity and social connection that take place at recess help children be more engaged once back in the classroom.

Pain and anxiety are linked to breathing in mouse brains – suggesting a potential target to prevent opioid overdose deaths

Opioids can cause death by slowing breathing to dangerously low levels, or stopping it altogether. Examining one area of the brain may eventually lead to safer painkillers.
