Sugar overload can cause heart damage

Your sweet tooth may be damaging your heart!Eating too much sugar can set people down a pathway to heart failure, a new study has warned.

A single small molecule, the glucose metabolite glucose 6-phosphate (G6P), causes stress to the heart that changes the muscle proteins and induces poor pump function leading to heart failure, according to the researchers at The University of Texas Health Science Center at Houston (UTHealth).

G6P can accumulate from eating too much starch and/or sugar, researchers said.

“Treatment is difficult. Physicians can give diuretics to control the fluid, and beta-blockers and ACE inhibitors to lower the stress on the heart and allow it to pump more economically,” said Heinrich Taegtmeyer, principal investigator and professor of cardiology at the UTHealth Medical School.

“But we still have these terrible statistics and no new treatment for the past 20 years,” said Taegtmeyer.

Taegtmeyer performed preclinical trials in animal models, as well as tests on tissue taken from patients at the Texas Heart Institute, who had a piece of the heart muscle removed in order to implant a left ventricle assist device. Both led to the discovery of the damage caused by G6P.

“When the heart muscle is already stressed from high blood pressure or other diseases, and then takes in too much glucose, it adds insult to injury,” Taegtmeyer said.

Scientist develops body-double robot

A Japanese scientist has developed a body-double robot which resembles him closely, with tiny human-like movements and blinking eyes.

Japanese roboticist Hiroshi Ishiguro, director of the Intelligent Robotics Laboratory at Osaka University, Japan, has been working on developing lifelike androids.

The new robot was unveiled at the Global Futures 2045 International Congress in New York, a futuristic conference focused on the technological singularity.

The new ‘Geminoid’, an android resembling a real person was tele-operated - controlled remotely - by a person offstage.

Ishiguro has also developed another Geminoid, a fashionably dressed female android, which he has shown off in the windows of clothing stores, LiveScience reported. The robot was so popular that the clothing it was modelling sold out immediately, Ishiguro said.

Ishiguro has also taken his robots on the road as part of a travelling “android theatre,” where they act out scenes with human-like expressions.

The roboticist also made the “Telenoid,” a pillow-like bot deliberately designed to appear ageless and genderless so that people can project an imagined face onto its neutral appearance.

At the end of Ishiguro’s talk, his robotic double spoke up, saying that next time, it would give a much better presentation than the real Ishiguro. 
60pc women ignorant of ovarian cancer symptoms

A study has revealed that almost six out of 10 women are unable to name any of the 10 symptoms of ovarian cancer.  The disease is the fourth most common cause of cancer deaths in women and experts fear the lack of awareness may contribute to low survival rates in the UK compared with elsewhere, the Independent reported. 

Symptoms include persistent bloating, pain in the abdomen, back or pelvis, and fatigue. No screening service is available for the cancer and five-year relative survival rates, at 36 percent, are among the lowest of the 21 most common cancers.

  Target Ovarian Cancer wants a national awareness campaign to alert women to the signs of the disease, which is diagnosed in nearly 7,000 women a year. Annwen Jones, the charity’s chief executive said that that it’s essential that women are made aware of the symptoms and that they are encouraged to visit their GP should they have any concerns.
