- 			 Health & Medicine Health & MedicinePlastic shards permeate human brainsA study of microplastics and nanoplastics in brains shows an astonishing increase over time. 
- 			 Health & Medicine Health & MedicineWelcome to The Deep End, a new podcast about brain implants and depressionThis new six-part podcast follows the lives of people with severe depression who volunteered for deep brain stimulation. 
- 			 Neuroscience NeuroscienceScratching an itch is so good, and so badThe motion kicks off inflammation but may also combat harmful bacteria 
- 			 Neuroscience NeuroscienceHow people suppress memories may be key to PTSD recoveryPeople who recovered from PTSD changed the way their brains handle intrusive thoughts, a study of survivors of the 2015 Paris terrorist attacks shows. 
- 			 Neuroscience NeuroscienceThe unique neural wiring of the human hippocampus may maximize memoryLiving tissue from the memory centers of people’s brains reveals sparse nerve cell connections that provide strong, reliable signaling between cells. 
- 			 Neuroscience NeuroscienceThe message-sending part of neurons may be blobby, not smoothAxons can be shaped like strings of pearls, research in mice and people show. How that shape may influence brain signaling is not yet clear. 
- 			 Anthropology AnthropologyHumans have linked emotions to the same body parts for 3,000 years3,000-year-old clay tablets show that some associations between emotion and parts of the body have remained the same for millennia. By Jason Bittel
- 			 Neuroscience NeuroscienceElectronic ‘tattoos’ offer an alternative to electrodes for brain monitoringA standard EEG test requires electrodes that come with pitfalls. A spray-on ink, capable of carrying electrical signals, avoids some of those. 
- 			 Neuroscience NeuroscienceLike brain cells, kidney cells can form memoriesScientists found memory’s molecular machinery at work in cells outside the nervous system. 
- 			 Neuroscience NeuroscienceSome people don’t have a mind’s eye. Scientists want to know whyThe senses of sight and sound are usually mingled in the brain, but not for people with aphantasia. 
- 			 Neuroscience NeuroscienceYour brain can perceive subtle odor changes in a single sniffThe speed at which our brain can tell smells apart is on par with color perception, a new sniff device shows. 
- 			 Neuroscience NeuroscienceHair pulling prompts one of the fastest known pain signalsThe ouch of hair pulling is transmitted with the help of a protein used to sense light touches. These details could lead to new treatments.
