- Health & Medicine
Malnutrition’s effects on the body don’t end when food arrives
Children may struggle with inflammation, a weakened immune system and gut problems. New treatments may repair some damage.
- Neuroscience
Biological puzzles abound in an up-close look at a human brain
Mirror-image nerve cells, tight bonds between neuron pairs and surprising axon swirls abound in a bit of gray matter smaller than a grain of rice.
- Neuroscience
Two distinct neural pathways may make opioids like fentanyl so addictive
A study in mice looked at how feelings of reward and withdrawal that opioids trigger play out in two separate circuits in the brain.
- Health & Medicine
Human body lice could harbor the plague and spread it through biting
Rats and fleas previously got all the blame, but humans’ own parasites could be involved.
- Environment
‘The High Seas’ tells of the many ways humans are laying claim to the ocean
The book explains how the race for ocean resources from fish to ores to new medicines — the Blue Acceleration — is playing out.
- Animals
Sumatran orangutans start crafting their engineering skills as infants
By 6 months old, young orangutans are experimenting with construction materials, and by 6 years old, they are building platforms 20 meters in the air.
- Neuroscience
The heart plays a hidden role in our mental health
Deciphering the messages that the heart sends to the brain could lead to new anxiety treatments and even unlock the secrets of consciousness.
