To Save Bees, Humans Need to Learn From the Past

- Adam Clare

Bees are having a hard time in the 21st century everything from radio waves to pesticides are messing with their honey creation. The poor creatures are also suffering from a massive colony collapse disorder. What’s more native species need to compete with colonies that are shipped around for farmers.

Fortunately there are still ways to help bees! Farmers in Mexico and India are using techniques learned over a millennium ago to keep their local bee populations surviving. No more pesticides or bizarre treatment of bees – instead these farmers help the bees help themselves (and humans).

On the eastern side of the Yucatan Peninsula, where large swaths of native forests are still intact, scientists interested in restoring that function are working with Mayan farmers to revive traditional beekeeping. The researchers’ long-term studies of bee populations and surveys of beekeepers in remote Mayan villages showed that the practice is no longer being passed down through families. To help preserve a tradition they saw as essential to preventing local extinction of these stingless bees Buchmann, Roubik, Villanueva-Gutiérrez, and other colleagues from the University of Yucatan started annual workshops to train a new generation of beekeepers.

Abstinence Only Sex Education Loses Funding in the USA

- Adam Clare

President Obama has cut funding for abstinence only sex education in the 2017 federal budget. The lack of adequate sex education has led to health crises and too many unwanted pregnancies (which is made worse by places lacking proper rights for women) in the USA. It’s so bad in some of the states that documentaries have been made about the horrible state of sex education, like the 2005 film The Education of Shelby Knox.

Decades of ignorance have led to an increase in health problems in absiteince only sex education areas, so it’s really good to se that Obama is making it harder for those places to teach ignorance.

This is an excellent, evidence-based move towards protecting and educating our youth. Whether or not they are given an abstinence-only sex education, teens are going to have sex. About half of all high school-aged youth reported having engaged in sexual intercourse. Contrary to what conservatives would want you to believe, states where abstinence-only education is emphasized have a higher teen pregnancy rate.
…

Abstinence-only education is a disservice to our youth. It encourages things such as “virginity pledges,” which are laughably ineffective. Teens who make such a pledge are just as likely to engage in oral or anal sex and have similar STI rates. Virginity pledges don’t work and actually increase the likelihood of risky sexual behavior.

The Future of Hospitals Will be Robotic

- Adam Clare

We like to think that people who work at hospitals do everything they can to save patients – and they do. The problem is that humans make mistakes. In fact, mistakes are so common in hospitals that a simple checklist can increase the care a patient receives. Robots, and computers, on the other hand easily follow checklists.

As we build better robotic systems (like autonomous cars and planes) we are building machines that perform tasks better than humans. In the world of health care we’re seeing that now and the speed at which robotic systems out perform humans will only increase. It means that the care you receive at a hospital will be better and more robotic.

There are programs to make diagnoses based on a series of questions, and algorithms inform many treatments used now by doctors.

Surgeons are already using robots in the operating theatre to assist with surgery. Currently, the surgeon remains in control with the machine being more of a slave than a master. As the machines improve, it will be possible for a trained technician to oversee the surgery and ultimately for the robot to be fully in charge.

Hospitals will be very different places in 20 years. Beds will be able to move autonomously transporting patients from the emergency room to the operating theatre, via X-ray if needed.

GyroGlove Helps Parkinson’s Patients with Hand Tremors

- Adam Clare 1 Comment

Parkinson’s is a neurological condition that interferes with a person’s ability to control fine muscle movements. This means that hand tremors, or other visible forms of shaking, cannot be finely controlled by someone with Parkinson’s. Student Faii Ong noticed this when he was helping a person with Parkinson’s trying to eat, and he decided to find a way to help.

Ong has designed a complex glove made of simple ideas that helps people with Parkinson’s control hand tremors. It all comes down to gyroscopes and cleverness.

Together with a number of other students from Imperial College London, Ong worked in the university’s prototyping laboratory to run numerous tests. An early prototype of a device, called GyroGlove, proved his instinct correct. Patients report that wearing the GyroGlove, which Ong believes to be the first wearable treatment solution for hand tremors, is like plunging your hand into thick syrup, where movement is free but simultaneously slowed. In benchtop tests, the team found the glove reduces tremors by up to 90 percent.

GyroGlove’s design is simple. It uses a miniature, dynamically adjustable gyroscope, which sits on the back of the hand, within a plastic casing attached to the glove’s material. When the device is switched on, the battery-powered gyroscope whirs to life. Its orientation is adjusted by a precession hinge and turntable, both controlled by a small circuit board, thereby pushing back against the wearer’s movements as the gyroscope tries to right itself.

Taxing Sugary Water Works

- Adam Clare

Beverages infused with copies amounts of sugar like Pepsi or Coke aren’t good for you health. When an entire nation consumes too much then public health suffers greatly. This has many governments looking into how they can stymie this overconsumption of unhealthy drinks. One solution is taxing soda sales.

in 2014 the Mexican government started such a tax and consumption has dropped. To prove its effectiveness researchers looked into how much of an impact the tax had on people drinking pop.

”
A study published Wednesday in the British Medical Journal suggests the tax is working: After one year, sales of sugar-sweetened drinks in Mexico dropped by 12 percent. And among poor households, which have the highest levels of obesity and untreated diabetes, sales fell by 17 percent.

…

These results are not surprising, but their empirical confirmation is of the greatest importance for governments that have opted to use taxes on sugar sweetened beverages as part of public health strategies, and those considering to do it,” wrote Franco Sassi, head of the public health program of the Organization for Economic Development and Cooperation.
