A few minutes of light exercise, rather than a sweaty gym workout, is all that is needed to reduce the risk of type 2 diabetes, study suggests

Even small amounts of physical activity can offer health benefits that protect against diabetesEven small amounts of physical activity can offer health benefits that protect against diabetes, new research suggests.

A new study found that even a little exercise wards off insulin resistance, a precursor to type 2 diabetes which can result from a high-fat diet.

Insulin resistance occurs when the cells of the body stop responding to insulin, a hormone that regulates blood sugar levels in the body.

Exercise can prevent insulin resistance by prompting the body to remove damaged cells and enhancing the quality of mitochondria, the cell’s energy powerhouses.

Type 2 diabetes affects 4.5 million people living in the UK and 29 million people in the US.

Even small amounts of physical activity can offer health benefits that protect against diabetes

The study also casts doubt on the previously held view that increasing the quantity of mitochondria could help fix some consequences of a high fat diet, including insulin resistance.

The researchers found that the benefits from physical activity were not affected by the quantity of mitochondria.

Lead researcher Megan Rosa-Caldwell, a doctoral student at the University of Arkansas, found that mice genetically engineered to have higher quantity of mitochondria were not more protected against high-fat diet induced insulin resistance.

How was the research conducted?

The researchers fed all the mice in the study a Western diet high in fat.

The genetically engineered and control mice were further divided into a group that was allowed to exercise, and a sedentary group.

Their results showed that physical activity, regardless of the amount of mitochondria, offered similar health benefits against insulin resistance.

The researchers said that it appears that exercise’s ability to help remove damaged cells and enhance the quality of the mitochondria may be more effective for preventing insulin resistance.

But they said these aspects need to be further tested.

Exercise offers ‘the greatest protection’

Ms Rosa-Caldwell said that with rates of obesity and type 2 diabetes continuing to increase, understanding the cellular processes that help or hurt insulin resistance can help doctors better tailor effective preventative measures such as exercise.

She added: ‘For now, physical activity is the greatest protection, but further research may enable us to prevent and treat insulin resistance, and subsequent diabetes, more effectively.’

The research was published in the journal Experimental Physiology.

Apple sells more Plus phones in Q4 2016 than ever

Apple is about to reveal its financial results for 4Q 2016 and they may contain a surprise – the company sold more iPhone 7 Plus units than any of the previous Plus-sized handsets. The company decided to equip the 7 Plus with more cameras, better battery life and more RAM than iPhone 7 and the result is said to be 24 million devices sold, compared with 15.5M iPhone 6s Plus phones in 4Q 2015. That’s 55% increase solely based on improving the hardware, compared with the flagship device from the same series.

Overall demand for the iPhone 7 has struggled throughout the October-December quarter which is first in Apple’s fiscal year. According to analysts from Cowen & Co, the data Apple is going to release tomorrow will reveal that people are unwilling to upgrade as often as expected. Part of the reason might be rumors about an 10-year Anniversary phone that kept a lot of consumers back when deciding to get the new iPhone.

The financial results show us also that this is the first time users in China preferred the Plus-sized iPhone to the regular one. 52% of the Apple fans decided to go with a iPhone 7 Plus compared with 40% who bought the predecessor iPhone 6s Plus.

This battery case will give your LG V20 more than 5 days life

The LG V20 has a 3,200 mAh battery that can easily get you through the day without any trouble. But if you are more extreme and power user probably even this wouldn’t be enough. And instead of buying a secondary battery, why don’t you actually consider the ZeroLemon option.

The case company released on Amazon their case at just $60. It comes with a 10,000mAh battery that goes in the same slot where the usual one goes. The removable back metal panel of V20 is substituted by the rubber bumper case that goes around the whole device plus, of course, the enormous battery.

There’s a cutout on the back for the fingerprint sensor/power button and the dual-camera module.

It looks bulky but doesn’t act like it. The whole package weights 230g but when you combine it with the V20 (without the original battery and back panel) it goes to just 330g.

Now this is a setup that can literally go a long way.

Bee, wasp stings more dangerous than snake, spider bites

An Australian research has discovered that venom from bees and wasps, rather than those from jellyfish, spiders or snakes, poses bigger public health threat, a study has revealed.

The Australia-first national analysis of 13 years’ data on bites and stings from venomous creatures, undertaken by the University of Melbourne, revealed that bees and wasps were responsible for a third of hospitalisations for venomous stings and bites, Xinhua news agency reported.

Spider bites were the second most prevalent cause of hospitalization in the 13-year period, accounting for 30 per cent of all admissions, while snake bites were third at 15 per cent.

Overall, 42,000 people were admitted to hospital for venomous bites or stings in the 13-year period and 64 people were killed, 34 of which were due to an allergic reaction to an insect bite that caused anaphylactic shock.

Ronelle Welton, a public health expert at the Australian Venom Unit at the University of Melbourne, said she was surprised that there were so many deaths and hospitalisations in the populated coastal areas of Australia.

“More than half of deaths happened at home, and almost two-thirds (64 percent) occurred, not in the isolated areas we might expect, but rather, in major cities and inner-regional areas where healthcare is readily accessible,” Welton said in a news release on Tuesday.

Welton said she believes the reason insect bites were so deadly was that people could be complacent in seeking medical attention and anaphylaxis can kill quickly.

Three quarters of those who died as a result of snake bites made it to hospital compared to just 44 per cent of those who were killed by insect bites.

Five things AI does better than humans, from the mundane to the magnificent

AIs are giving us a kicking in board games and video games, but what else are they good for?

COMMENTS
For millennia, we surpassed the other intelligent species with which we share our planetdolphins, porpoises, orangutans, and the likein almost all skills, bar swimming and tree-climbing.

In recent years, though, our species has created new forms of intelligence, able to outperform us in other ways. One of the most famous of these artificial intelligences (AIs) is AlphaGo, developed by Deepmind. In just a few years, it has learned to play the 4,000-year-old strategy game, Go, beating two of the worlds strongest players.

Other software developed by Deepmind has learned to play classic eight-bit video games, notably Breakout, in which players must use a bat to hit a ball at a wall, knocking bricks out of it. CEO Demis Hassabis is fond of saying that the software figured out how to beat the game purely from the pixels on the screen, often glossing over the fact that the company first taught it how to count and how to read the on-screen score, and gave it the explicit goal of maximizing that score. Even the smartest AIs need a few hints about our social mores.

But what else are AIs good for? Here are five tasks in which they can equal, or surpass, humans.

Building wooden block towers

AIs dont just play video games, they play with traditional toys, too. Like us, they get some of their earliest physics lessons from playing with wooden blocks, piling them up then watching them fall. Researchers at Facebook have built an AI using convolutional neural networks that can attain human-level performance at predicting how towers of blocks will fall, simply by watching films and animations of block towers standing or falling.

Lip-reading

Lip-readingfiguring out what someone is saying from the movement of their lips alonecan be a useful skill if youre hard of hearing or working in a noisy environment, but its notoriously difficult. Much of the information contained in human speechthe position of the teeth and tongue, and whether sounds are voiced or notis invisible to a lip reader, whether human or AI. Nevertheless, researchers at the University of Oxford, England, have developed a system called LipNet that can lip-read short sentences with a word error rate of 6.6 percent. Three human lip-readers participating in the research had error rates between 35.5 percent and 57.3 percent.

Among the applications the researchers see for their work are silent dictation and speech recognition in noisy environments, where the visual component will add to accuracy. Since the AIs output is text, it could find work close-captioning TV shows for broadcast networksor transcribing surveillance video for security services.

Transcribing

AIs can be even more helpful when the audio quality is better, according to Microsoft, where researchers have been tweaking an AI-based automated speech recognition system so it performs as well as, or better than, people. Microsofts system now has an error rate of 5.9 percent on one test set from the National Institute of Standards and Technology, the same as a service employing human transcribers that Microsoft hired, and 11.1 percent on another test, narrowly beating the humans, who scored 11.3 percent.

Thats one situation where being better than a human might not be sufficient: If you were thinking you could dictate your next memo, you might find it quicker to type and correct it yourself, even with just two fingers.

News reporting

This story was written by a human, but the next one you read might be written by an AI.

And that might not be a bad thing: MogIA, developed by the Indian company Genic, doesnt write stories, but when MogIA predicted Donald Trump would win the U.S. presidential election it did better than most political journalists.

When it comes to writing, AIs are particularly quick at turning structured data into words, as a Financial Times journalist found when pitted against an AI called Emma from Californian startup Stealth.

Emma filed a story on unemployment statistics just 12 minutes after the figures were released, three times faster than the FTs journalist. While the AIs copy was clear and accurate, it missed the news angle: the number of jobseekers had risen for the first time in a year. While readers want news fast, its not for nothing that journalists are exhorted to get it first, but first, get it right.

Putting those employment statistics in context would have required knowledge that Emma apparently didnt have, but thats not an insurmountable problem. By reading dictionaries, encyclopedias, novels, plays, and assorted reference materials, another AI, IBMs Watson, famously learned enough context to win the general knowledge quiz show Jeopardy.

Disease diagnosis

After that victory, Watson went to medical school, absorbing 15 million pages of medical textbooks and academic papers about oncology. According to some reports, that has allowed Watson to diagnose cancer cases that stumped human doctors, although IBM pitches the AI as an aid to human diagnosis, not a replacement for it.

More recently, IBM has put Watsons ability to absorb huge volumes of information to work helping diagnose rare illnesses, some of which most doctors might see only a few cases of in a lifetime.

Doctors in the Centre for Undiagnosed and Rare Diseases at University Hospital Marburg, in Germany, will use this instance of Watson to help them deal with the thousands of patients referred to them each year, some of them bringing thousands of pages of medical records to be analyzed.

Authors including Vernor Vinge and Ray Kurzweil have postulated that AI technology will develop to a point, still many years off, that they call the singularity, when the combined problem-solving capacity of the human race will be overtaken by that of artificial intelligences.

If the singularity arrives in our lifetimes, some of us might be able to thank AIs like Watson for helping keep us alive long enough to see it.

Smoking hookah at home pollutes indoor air more than cigarettes

Smoking hookah at home pollutes indoor air more than cigarettesSmoking hookah at home pollutes indoor air more than cigarettes
People smoking hookah in their homes generate carbon monoxide, a toxic gas, and tiny pollution particles known as PM 2.5 at levels at least double those produced by cigarettes, according to a recent study in Dubai.

Even in the rooms adjacent to where people smoked hookah, air pollution levels were much higher than in rooms where cigarettes were actively smoked, researchers report in the journal Tobacco Control. “There are widespread misconceptions that hookah is a safer alternative to cigarettes,” said lead author Dr. Michael Weitzman, a professor at New York University School of Medicine.

“Smoking hookahs (water pipes) at home can be terribly dangerous for the smoker, but perhaps more importantly, for children and other people living in the home,” Weitzman told Reuters Health by email. During one hookah-smoking session, a smoker can inhale the equivalent of the smoke from 150 cigarettes, according to the U.S. Centers for Disease Control and Prevention.

Hookahs are among alternative tobacco products like chewing tobacco whose use has been on the rise in the U.S., especially among young people, the study authors note. Among high school students, 14 percent of girls and 15 percent of boys said they had used a hookah in 2014, as did one quarter of young adults in 2015.

To determine the effect smoking has on indoor environments, the study team collected air samples from 33 homes in Dubai: 11 where only hookah smokingoccurred, 12 with only cigarette smoking and 10 with no smoking at all.

The study team sampled the air quality in the rooms where people smoked and in an adjacent room during about one hour of hookah or cigarette smoking, and compared the readings to nonsmoking homes.

The researchers used air filters to measure levels of carbon monoxide, black carbon and pollution particles 2.5 microns or smaller (PM 2.5), which can penetrate deep into the lungs and enter the bloodstream.

During sampling sessions, there were between one and four active hookah smokers, with an average of 1.7, and one to five active cigarette smokers, with an average of 2.3. In rooms where hookahs were being smoked, carbon monoxide levels averaged 11 parts per million and the PM 2.5 level was 489 micrograms per cubic meter of air. In the adjacent room, carbon monoxide levels averaged 5.8 ppm and PM 2.5 pollution was 211 micrograms/m3.

In rooms with cigarette smoking, carbon monoxide averaged 2.3 ppm and PM 2.5 averaged 201 micrograms. Levels in the adjacent room were about half. In nonsmoking homes, carbon monoxide levels averaged 1.5 ppm while PM 2.5 levels averaged 93 micrograms. Black carbon levels during active smoking were 5.4 micrograms/m3 with active hookah smoking, 4.2 with active cigarette smoking and 2.1 in nonsmoking homes.

There is no regulatory standard for black carbon levels, the authors write, but the U.S. Environmental Protection Agency says being exposed to more than 9 ppm of carbon monoxide over an eight-hour period is unsafe and the World Health Organization limits PM 2.5 exposure in outdoor air to 35 micrograms/m3 over 24 hours

Smoking may harm HIV patients more than the virus itself

Among people living with HIVwho smoke cigarettes, smokingmay shorten their lifespan more than HIV itself, warns a study by an Indian-origin researcher.

“A person with HIV who consistently takes HIV medicines but smokes is much more likely to die of a smoking-related disease than of HIV itself,” explained study author Krishna P. Reddy of the Massachusetts General Hospital and Harvard Medical School.

The study suggests that making smoking cessation a priority and finding effective ways to help people with HIV quit can significantly improve their lifespan.

“Now that HIV-specific medicines are so effective against the virus itself, we also need to add other interventions that could improve and extend the lives of people with HIV,” Reddy noted.

In their study, the researchers used a computer simulation of HIV disease and treatment to project the life expectancy of people living with HIV based on their smoking status.

For men and women with HIV who adhere well to HIV medicines, the study, published in The Journal of Infectious Diseases, found that smoking reduces life expectancy by about twice as much as HIV.

“It is well-known that smoking is bad for health, but we demonstrate in this study just how bad it is,” Reddy said.

Smoking is especially dangerous for people living with HIV, putting them at high risk for heart disease, cancer, serious lung diseases, and other infections.

“We actually quantify the risk, and I think providing those numbers to patients can help put their own risks from smoking in perspective,” Reddy noted

IT@School Project: More than 10,000 Kerala schools to be on wiki platform

On occasion of Kerala Formation Day, the state government will be re-launching the [email protected] that was designed to impart IT education in schools by setting ‘School Wiki’ on the lines of Wikipedia.

Launched on November 1, 2009, School Wiki was inactive for almost two years.

As per reports, this project also aims at encouraging knowledge generation and sharing among students and teachers.

Details of the project:

  • The whole portal is made entirely in Malayalam language
  • School Wiki features a unique content collection jointly undertaken by the students and teachers
  • Along with alumni and public, 15,000 schools from class 1 to 12 in the state have lent a helping hand in this project
  • This has been prepared using Wikemedia Foundation’s Wikemedia software.

Meanwhile, speaking about his project, K Anvar Sadath, Executive Director of [email protected] Project said, “[email protected] Project has made arrangements for specific training for teachers and students for using School Wiki and identify and assign district level admins for data accuracy and modifications and provide necessary support.”

Features of [email protected]:

  • Now just by logging into School Wiki, all schools would be able to fill in and update basic elementary details
  • Also, schools would be able to upload details such as infrastructure data, renowned alumni, school websites, school map, blogs, various clubs and forums, class magazines, supporting images and videos
  • Furthermore, this platform will have educational contents prepared by students, as well as teaching
  • And analytical Malayalam language projects such as “School Patram – [School Newsletter]”, “Nadodi Vijnanakoshan – [Local Encyclopedia] “and “Ente Nadu-[My Village]” would also be there

Not only this, state Education Minister Prof C Raveendranath said, “Awards would be given to those schools that make use of and maintain School Wiki in the most effective manner.”

iOS 10 is running on 66% of devices less than a month after release

iOS 10 is running on 66% of devices less than a month after release

iOS 10 officially went out on September 13. And today, less than one month from that moment, 66% of supported devices are already running the latest version of Apple’s mobile operating system.

This is a record breaking achievement, even compared to past iOS updates. They all do well when it comes to adoption (especially against Android), but iOS 10 has been a breakout hit. As you can see from the metrics portrayed below, no other iOS release has reached such a big install base in such a short amount of time before.

Interestingly, the adoption rate of iOS 10 initially lagged way behind what iOS 6, 7, and 9 saw for approximately the first two weeks. After that, however, the latest iteration of the software quickly gained more installs than those three. It’s unclear what caused this sudden uptick. Perhaps a lot of iPhone 7 and 7 Plus units were shipped around that time, or maybe Apple only notified users of older iOS versions about the new one around two weeks after its initial outing.

Making iOS 10.0.2 available on September 23 may have contributed too in some way, although the truth is no one knows for sure why the adoption curve for iOS 10 looks the way it does. Regardless, it seems like iOS 10 may be on track to become one of Apple’s most successful releases ever, if not the most successful – in terms of how many people choose to jump to it on their devices.
