Understanding cobalt’s human cost

Posted: 17 Dec 2021 08:32 AM PST

After studying the impacts of mining cobalt -- a common ingredient in lithium-ion batteries -- on communities in Africa's Democratic Republic of the Congo (DRC), an interdisciplinary team of researchers is calling for more data into how emerging technologies affect human health and livelihoods.

Pain and anxiety impact breathing on a cellular level

Posted: 17 Dec 2021 08:29 AM PST

A team of scientists has uncovered a neural network in the brain that coordinates breathing rhythm with feelings of pain and fear. Along with contributions to the fields of pain management, psychological theories of anxiety, and philosophical investigations into the nature of pain, their findings could lead to development of an analgesic that would prevent opioid-induced respiratory depression (OIRD), the disrupted breathing that causes overdose deaths.

Research takes early step towards drug to treat common diabetes complication hypoglycemia

Posted: 17 Dec 2021 07:28 AM PST

New research has taken an important step towards the goal for a treatment for the common diabetes complication hypoglycemia, or low blood sugar. Researchers found a way help to defend against hypoglycemia by boosting hormonal defense systems. The team believes they have identified a promising target in the brain could be useful for future drug development to create an anti-hypoglycemia drug.

Redrawing the lines: Growing inexpensive, high-quality iron-based superconductors

Posted: 17 Dec 2021 07:28 AM PST

Superconducting materials show zero electrical resistance at low temperatures, which allows them to conduct 'supercurrents' without dissipation. Recently, a group of scientists developed an inexpensive, scalable way to produce high-temperature superconductors using 'grain boundary engineering' techniques. The new method could help develop stronger, inexpensive, and high operating temperature superconductors with impactful technological applications.

Ocean acidification and warming disrupts fish shoals

Researchers have found that the way fish interact in groups is being upset by ocean acidification and global warming.

Rollercoaster of emotions: Exploring emotions with virtual reality

Posted: 17 Dec 2021 07:28 AM PST

To the left and right, the landscape drifts idly by, the track in front of you. Suddenly, a fire. The tension builds. The ride reaches its highest point. Only one thing lies ahead: the abyss. Plummeting down into the depths of the earth. These are scenes of a rollercoaster ride as experienced by participants in a recent study. However, not in real life, but virtually, with the help of virtual reality (VR) glasses. The aim of the research was to find out what happens in participants' brains while they experience emotionally engaging situations.
