Skin Cell Model Advances Study of Genetic Mutation Linked to Heart Disease, Stroke Risk

Using a new skin cell model, researchers have overcome a barrier that previously prevented the study of living tissue from people at risk for early heart disease and stroke. This research could lead to a new understanding of disease progression in aortic aneurysm – ballooning of the large artery in the chest that carries blood from the heart to the body.

Messages with Moral-Emotional Words Are More Likely to Go Viral on Social Media

Tweets about political topics that include moral and emotional language are more likely to spread within the ideological networks of the sender, a team of researchers has found. Its study examined Twitter messages related to gun control, climate change, and same-sex marriage.

New Class of 'Soft' Semiconductors Could Transform HD Displays

New research by Berkeley Lab scientists could help usher in a new generation of high-definition displays, optoelectronic devices, photodetectors, and more. They have shown that a class of “soft” semiconductors can be used to emit multiple, bright colors from a single nanowire at resolutions as small as 500 nanometers. The work could challenge quantum dot displays that rely upon traditional semiconductor nanocrystals to emit light.

Could This Strategy Bring High-Speed Communications to the Deep Sea?

A new strategy for sending acoustic waves through water could potentially open up the world of high-speed communications to divers, marine research vessels, remote ocean monitors, deep sea robots, and submarines. By taking advantage of the dynamic rotation generated as the acoustic wave travels, also known as its orbital angular momentum, Berkeley Lab researchers were able to pack more channels onto a single frequency, effectively increasing the amount of information capable of being transmitted.

Study: Exposure to Light Causes Emotional and Physical Responses in Migraine Sufferers

This research found that light makes migraine headaches more painful and induces negative emotions and unpleasant physical sensations. Laboratory studies identify previously unknown connections between nerve cells in the eye and neurons in the brain that regulate physiological, autonomic, endocrine and emotional responses. These findings offer promising path forward for researchers in treatment of migraines.

Where Cigarette Smoking’s Damage is Done . . . Down to Your DNA

SANCAR_BaP_carcinogen.jpg

Scientists have known for decades that smoking cigarettes causes DNA damage, which leads to lung cancer. Now, for the first time, UNC School of Medicine scientists created a method for effectively mapping that DNA damage at high resolution across the genome.

Musical Mystery: Researchers Examine Science Behind Performer Movements

1G2A0589_low.jpg

Researchers at McMaster are one step closer to solving one of the mysteries of social interaction: how musicians communicate during a performance and anticipate one another’s moves without saying a word. The findings are important because a clearer appreciation of how musicians silently work together—across tempo changes, phrasing and musical dynamics—will improve our understanding of nonverbal communication. That could lead to better techniques to reach those with conditions such as autism or dementia, say researchers.

3.3 Million-Year-Old Fossil Reveals Origins of the Human Spine

selam-vertebrae.jpg

Analysis of a 3.3 million-year-old fossil skeleton reveals the most complete spinal column of any early human relative, including vertebrae, neck and rib cage. The findings, published this week in the Proceedings of the National Academy of Sciences, indicate that portions of the human spinal structure that enable efficient walking motions were established millions of years earlier than previously thought.
