Stress and Brain: Jaime Tartar
Jaime Tartar tells us about how the brain interprets what is stressful, how it determines our behavioral and physiological response to stressors, and how it can be damaged by stress. She will discuss how the body’s reaction to acute stress has protective and adaptive effects in the short run while chronic stress can lead to poor health consequences such as decreased memory performance and depression.
How to cope with anxiety: Olivia Remes
Anxiety is one of most prevalent mental health disorders, with 1 out of 14 people around the world being likely affected. Leading up to conditions such as depression, increased risk for suicide, disability and requirement of high health services, very few people who often need treatment actually receive it…
In her talk “How to cope with anxiety”, Olivia Remes of the University of Cambridge will share her vision on anxiety and will unravel ways to treat and manage this health disorder. Arguing that treatments such as psychotherapy and medication exist and often result in poor outcome and high rates of relapses, she will emphasise the importance of harnessing strength in ourselves as we modify our problem-coping mechanisms.
Olivia will stress that by allowing ourselves to believe that what happens in life is comprehensive, meaningful, and manageable, one can significantly improve their risk of developing anxiety disorders. At TEDxUHasselt 2017, Olivia will stress that by allowing ourselves to believe that what happens in life is comprehensive, meaningful, and manageable, one can significantly improve their risk of developing anxiety disorders.
Specialized Neurons That Respond to Pain of Pulling Single Hair Discovered
Summary: NIH researchers have identified a specific type of sensory neurons which become activated as a result of pulling a single hair.
Source: NIH.
Researchers from the National Institutes of Health have identified a class of sensory neurons (nerve cells that electrically send and receive messages between the body and brain) that can be activated by stimuli as precise as the pulling of a single hair. Understanding basic mechanisms underlying these different types of responses will be an important step toward the rational design of new approaches to pain therapy. The findings were published in the journal Neuron.
The Adult Brain Can Regenerate Neurons in an Unexpected Area, Says New Study
Scientists have discovered for the first time that adult mouse brains produce new cells in the amygdala, a finding that could eventually lead to better treatments for conditions like anxiety and depression, as well as a better understanding of the brain overall.
The amygdala handles a lot of our emotional responses, especially those relating to fear, and broken connections inside it can lead to anxiety disorders such as post-traumatic stress disorder (PTSD).
If the brain is capable of regenerating neurons in the amygdala, then that’s potentially one way of fighting back against these mental health issues, according to the team from the University of Queensland in Australia.
Cure to deadly peanut allergy FINALLY found in Australian breakthrough
Children with peanut allergies could finally overcome the life-threatening reaction for up to four years, Australian researchers say.
Following a major breakthrough that could lead to a cure, the small clinical trial found two-thirds of children who were given an experimental immunotherapy treatment were rid of their allergy.
The kids with peanut allergies were given a probiotic treatment called lactobacillus rhamnosus, with a peanut protein, once daily for 18 months.
NYC is getting a huge new VR conference this fall
In addition to an upcoming virtual reality hub at NYU, New York City will also host its first VR-focused convention later this year. The NYVR Expo, which will take place at the Javits Center from Oct. 26th through 28th, aims to be the biggest virtual reality conference on the East Coast. It’ll be a place for both newcomers and existing VR professionals to explore what’s next in the burgeoning medium. And since the NYVR Expo will run alongside the PhotoPlus Expo at Javits, it will have easy reach to a wide audience of media enthusiasts.
According to Emerald Expositions, which organizes both shows, the new event came about after it noticed that PhotoPlus Expo attendees were increasingly interested in VR. While it considered creating a small virtual reality pavilion as part of the existing show, according to Senior Vice President John McGeary, the company realized it made more sense to start a completely new conference. Together, both the NYVR Expo and PhotoPlus Expo are expected to gather around 20,000 attendees.
As you’d expect, the virtual reality conference will show off how the technology can be used in a variety of sectors, including health care, education and entertainment. It’ll also take advantage of NYC’s unique position as a melting pot for a variety of industries.
The Government Must Review What Bioresearch Journals Publish
It’s getting too easy to create dangerous viruses. The upcoming national biodefense strategy should ensure that scientific journals don’t help terrorists learn how.
The news that researchers have recreated an extinct cousin to the smallpox virus using only commercially available technology and items purchased over the Internet renews concerns that bioterrorists could do the same if detailed information about the methods were published. Here’s the problem: scientific journals are geared toward publication, often without sufficient understanding of the public-security risks. We need a better system to ensure that information that could help bad actors stays unpublished.
It took David Evans’ team of scientists at the University of Alberta in Edmonton, Canada, about six months and $100,000 to recreate the horsepox virus, a close relative of the smallpox virus that killed perhaps 300 million people in the 20th century before it was eradicated in 1980. In a summary of the research, the World Health Advisory Committee on Variola Virus Research wrote that “recreation of such viral genomes did not require exceptional biochemical knowledge or skills, significant funds, or significant time.”
People Who Earn More, Have More Sex, and Vice Versa
There is an interdependent relationship among making money, having sex, and being physically healthy, according to new research published in the International Journal of Manpower.
The study found that workers who have sex two to three times per week earn an average of 4.5 percent more than coworkers who have sex less often. Based on a behavioral study that surveyed 7,500 individuals, researchers found that” workers with health problems who are sexually active earn 1.5 percent more than those with similar ailments who are not sexually active.”
Dr. Nick Drydakis, who led the study from Anglia Ruskin University, concluded that having a higher income results in leading a more active sex life, and that having more sex supports our efforts at the office:
Comparing Reactions of different Groups to Nuclear Thermal Rocket enabled space colonization
Nextbigfuture wrote about the designs for an improved nuclear thermal rocket by John Bucknell. John has worked as a senior engineer on the SpaceX Raptor rocket. John provides high quality qualified work to his rocket designs and to his proposed space habitat.
Nextbigfuture comments had some technical observations about Project Timberwind and a comment from John himself that his design improves on flaws in the last major nuclear thermal rocket experiments. There were also comments and discussion about Star Trek and communism and O’Neill space stations.
Reddit futurology had two comments. One positive comment by the submitter and a negative comment complaining that the factual title was hype./a The title was trying to condense the concept that John’s habitat would have full Earth gravity and full radiation shielding. Colonies on the surface of Mars would have 38% of Earth gravity and colonies on the surface of the moon would have 16% of Earth gravity. Living in the current International space station is a microgravity environment with more radiation. It is well known that long term exposure to lower gravity is a problem. Muscles weaken bones thin out stress is placed on blood vessels Serious effort is needed to exercise while in low gravity to reduce effects and physiotherapy is needed to recover from the stays in orbit or on the Moon where there is low or no-gravity. Yet the title “Constructing full earth like conditions in Space with technology proven in the sixties” is claimed to be hype.
