A new paper suggests that an increase in mobile phone ownership could have led to a rise in mental health problems in young people.

Aggressive brain tumour cells taken from patients self-destructed after being exposed to a chemical in laboratory tests, researchers have shown.
The study could be the first step in tackling cancers like glioblastoma, which led to Dame Tessa Jowell’s death earlier this year.
The research, led by the University of Leeds, found that the synthetic chemical, named KHS101, was able to cut the energy source of tumour cells from glioblastoma, leading to the death of the cells.

Imagine something similar to the Great Depression of 1929 hitting the world, but this time it never ends.
Economic modelling suggests this is the reality facing us if we continue emitting greenhouse gases and allowing temperatures to rise unabated.
Economists have largely underestimated the global economic damages from climate change, partly as a result of averaging these effects across countries and regions, but also because the likely behaviour of producers and consumers in a climate change future isn’t usually taken into consideration in climate modelling.

“There are more synapses in a human brain than there are stars in the galaxy. The brain is the most complex object we know of and understanding its connections at this level is a major step forward in unravelling its mysteries,” said lead author Dr. Seth Grant at the Center for Clinical Brain Sciences.
Imagine a map of every single star in an entire galaxy. A map so detailed that it lays out what each star looks like, what they’re made of, and how each star is connected to another through the grand physical laws of the cosmos.
While we don’t yet have such an astronomical map of the heavens, thanks to a momentous study published last week in Neuron, there is now one for the brain.
If every neuron were a galaxy, then synapses—small structures dotted along the serpentine extensions of neurons—are its stars. In a technical tour-de-force, a team from the University of Edinburgh in the UK constructed the first detailed map of every single synapse in the mouse brain.
For centuries humans have sought the ‘elixir of life’ – a mythical potion that supposedly would grant the drinker eternal life.
Now Exeter scientists believe they may have found the secret to a longer, healthier life.
New compounds developed and tested at the University of Exeter have brought the dream a step closer and paved the way for “anti-degeneration” drugs that could not only extend life, but also extend health and may help treat age-related diseases like cancer, dementia and diabetes.

Like a team in a science fiction movie, the six-lab squad funded by a 2017 MEDx Biomedical research grant is striking in its combination of diverse skills and duties.
The project is led by Kafui Dzirasa, MD’09, Ph.D.’07, HS’10-’16, associate professor of psychiatry and behavioral sciences and assistant professor in neurobiology and neurosurgery; and Nenad Bursac, Ph.D., professor of biomedical engineering and associate professor in medicine. Their team includes: Marc Caron, Ph.D., James B. Duke Professor of Cell Biology, professor in neurobiology and medicine; Fan Wang, Ph.D., professor of neurobiology; Christopher Kontos, MD, HS’93-’97, professor of medicine and associate professor of pharmacology and cancer biology—all at Duke University School of Medicine—and Jennie Leach, Ph.D., associate professor of chemical, biochemical, and environmental engineering at the University of Maryland Baltimore County, along with a cadre of committed graduate students, postdocs, and technicians.
Dzirasa’s background in engineering informs his approach to the study of neuropsychiatric illness and disease. In the summer of 2016, he and members of his lab were discussing the challenge of precisely monitoring brain activity.
