“He was never the same after Chris’s death”: How Linkin Park singer Chester Bennington, 41, hanged himself on birthday of late friend Chris Cornell – despite friends believing he “was in a good place.”

Friends and family of Linkin Park lead singer Chester Bennington are in absolute “shock” over the rock star's apparent suicide as it's revealed they believed he “was in a good place in his life”.
The 41-year-old was found dead in his home in Palos Verdes near Los Angeles shortly before 9am on Thursday.
A Los Angeles County coroner confirmed they were investigating Bennington's death as an apparent suicide but no additional details were available. 
Law enforcement officials say Bennington hanged himself in his bedroom and he was home alone at the time, according to TMZ. He was found upstairs by his housekeeper.
'”Chester was one of the brightest and most talented people on this planet, and he lived life to the fullest,” a close friend told RadarOnline, adding that the Bennington suffered from demons. 
Bennington's suicide came on the day of his late lifelong friend Chris Cornell's birthday. The Soundgarden rocker killed himself in May by hanging. Cornell would have turned 53.
“Chester and Chris were so close, and he was never the same after Chris’s death,” the friend told Radar.
The friend of Bennington's also noted that Cornell's death deeply affected Bennington, who also struggled with “addiction issues”.
“But everyone thought that he had it licked. He seemed to be at a good place in his life. It is just so tragic and there are no words,” the friend told Radar. 
 
His bandmates were said to be blindsided by Chester's suicide with sources telling TMZ they had plans to attend a photo shoot in Hollywood later on Thursday. 
 One Linkin Park band member went to pick him up on Thursday morning but arrived to find police already at his home.
The singer had a history of drug and alcohol abuse. He was married and is survived by his six children from two relationships. 
Chester had flown back to Los Angeles on Wednesday night. He had been spending time in Arizona with his wife Talinda, but she remained behind. 
Chester, as well as Linkin Park guitarist Brad Delson, had performed Leonard Cohen's “Hallelujah” for the crowd of mourners at Cornell's funeral, many of whom were moved to tears. 
Linkin Park was on tour following the release of the band's latest album One More Light. They had a show at New York's Citi Field scheduled for next week with Blink 182. 
They played together for the last time on July 7 in Birmingham, England. 
The band released its newest music video just two hours before news of his death emerged on Thursday. 
Bennington was married to his second wife Talinda, a former Playboy model, for 12 years. He divorced his first wife Samantha Marie Olit in 2005 after nine years of marriage. 
The frontman had been open about his history of substance abuse and admitted in one interview in 2011 that he had once been a “full blown, raging alcoholic”. 
He admitted to smoking pot after his parents divorced when he was 11. The drug use then spiraled into cocaine and meth. 
Bennington had also previously spoken out about being sexually abused as a seven-year-old, saying he had been molested by an older male friend.
“If I think back to when I was really young, to when I was being molested, to when all these horrible things were going on around me, I shudder,” he said in one interview. 
He went to rehab for his drug and alcohol addiction after marrying his second wife and said he really began to change in 2007. 
In a 2011 interview, he said he was sober.
“I don't drink. I choose to be sober now. I have drunk over the last six years, but I just don't want to be that person anymore.” 
Linkin Park's sixth and latest album, One More Light, jumped to the top of the Billboard chart when it was released in May. [...]

Is gene editing ethical?


Gene editing is the modification of DNA sequences in living cells. What that means in reality is that researchers can either add mutations or substitute genes in cells or organisms. 
Gene editing holds the key to preventing or treating debilitating genetic diseases, giving hope to millions of people around the world. Yet the same technology could unlock the path to designing our future children, enhancing their genome by selecting desirable traits such as height, eye color, and intelligence. 
While this concept is not new, a real breakthrough came 5 years ago when several scientists saw the potential of a system called CRISPR/Cas9 to edit the human genome.
CRISPR/Cas9 allows us to target specific locations in the genome with much more precision than previous techniques. This process allows a faulty gene to be replaced with a non-faulty copy, making this technology attractive to those looking to cure genetic diseases. 
The technology is not foolproof, however. Scientists have been modifying genes for decades, but there are always trade-offs. We have yet to develop a technique that works 100 percent and doesn't lead to unwanted and uncontrollable mutations in other locations in the genome.
In a laboratory experiment, these so-called off-target effects are not the end of the world. But when it comes to gene editing in humans, this is a major stumbling block.
The fact that gene editing is possible in human embryos has opened a Pandora's box of ethical issues.
Here, the ethical debate around gene editing really gets off the ground. 
When gene editing is used in embryos — or earlier, on the sperm or egg of carriers of genetic mutations — it is called germline gene editing. The big issue here is that it affects both the individual receiving the treatment and their future children. 
This is a potential game-changer as it implies that we may be able to change the genetic makeup of entire generations on a permanent basis.

Indian surgeons separate twins joined at the head 


Two-year-old Jaga and Kalia underwent 16 hours of surgery, and are now in the intensive care unit, doctors said. 
A team of 30 doctors carried out the surgery - the first of its kind in India - at a state-run hospital. 
The boys were born with shared blood vessels and brain tissues, a very rare condition that occurs once in about three million births. 
The director of the All India Institute of Medical Sciences, Randeep Guleria, told the Press Trust of India that the "next 18 days would be extremely critical to ascertain the success of the surgery". 
The twins, hailing from a village in eastern Orissa state, were joined at the head - a condition known as craniopagus. 
Even before the operation they had defeated the odds; craniopagus occurs in one in three million births, and 50% of those affected die within 24 hours, doctors say. 
"Both the children have other health issues as well. While Jaga has heart issues, Kalia has kidney problems," neurosurgeon A K Mahapatra said. 
"Though initially Jaga was healthier, now his condition has deteriorated. Kalia is better," he added. 
Doctors said the most challenging job after the separation was to "provide a skin cover on both sides of the brain for the children as the surgery had left large holes on their heads". 
"If the twins make it, the next step will be reconstructing their skulls," plastic surgeon Maneesh Singhal said. 
The first surgery was performed on 28 August when the doctors created a bypass to separate the shared veins that return blood to the heart from the brain.

Virtual reality may help relieve phantom limb pain.

In a recent study, patients experienced reduced phantom limb pain after playing an augmented reality car racing game that required them to move the missing limb. Phantom limb pain is the experience of pain in a limb after it has been amputated. 
The underlying mechanisms responsible for phantom limb pain remain unclear. However, it appears that it may arise as a consequence of abnormal neural circuitry in central areas of the brain.
Limited success has been achieved with mirror therapy in which reflections of the unaffected limb can be used to create the illusion that the amputated limb is moving. 
The latest study has taken the mirror therapy concept a step further; patients visualise and 'move' the phantom limb using augmented reality—‘phantom motor execution’. It was conducted in 14 patients who had been experiencing phantom limb pain since the amputation of an arm. 
Sensors that could detect muscular activity were attached to the stump of the missing arm. The signals received by these sensors were then used to produce an image of an active arm on a computer screen. 
Patients were trained to use these signals to control the virtual arm, drive a virtual race car around a track and to copy the movements of an arm on screen with their phantom movements. After twelve 2-hour treatment sessions, the patients underwent follow-up interviews 1, 3 and 6 months later. 
Based on the patients' ratings, the intensity, quality, and frequency of pain had reduced by 50% after the treatment.
At the start of the study, 12 patients reported feeling constant pain whereas only 6 did 6months after the treatment. However, one patient thought that there was not a considerable difference in the levels of phantom pain before and after treatment.

Most teenagers happy with their lives but schoolwork anxiety and bullying an issue

Teenagers who feel part of a school community and enjoy good relations with their parents and teachers are more likely to perform better academically and be happier with their lives, according to the first OECD PISA assessment of students’ well-being.

PISA 2015 Results analyses for the first time students’ motivation to perform well in school, their relationships with peers and teachers, their home life, and how they spend their time outside of school. The findings are based on a survey of 540,000 students in 72 participating countries and economies who also completed the main OECD PISA 2015 test on science, mathematics and reading.

Many students are very anxious about school work and tests and the analysis reveals this is not related to the number of school hours or the frequency of tests but with how supportive they feel their teachers and schools to be: on average across OECD countries, 59% of students reported they often worry that taking a test will be difficult, and 66% reported feeling stressed about poor grades. Some 55% of students say they are very anxious for a test even if they are well prepared. In all countries, girls reported greater schoolwork-related anxiety than boys; and anxiety about schoolwork, homework and tests is negatively related to performance.

Teachers play a big role in creating the conditions for students’ well-being at school and governments should not define the role of teachers solely through the number of instruction hours. Happier students tend to report positive relations with their teachers. Students in schools where life satisfaction is above the national average reported a higher level of support from their teacher than students in schools where life satisfaction is below average.

“These findings show how teachers, schools and parents can make a real difference to children’s well-being,” said OECD Chief of Staff Gabriela Ramos, launching the report in London. “Together they can help young people develop a sense of control over their future and the resilience they need to be successful in life. There is no secret, you perform better if you feel valued, if you feel well treated, if you are given a hand to succeed!”

Natural tooth repair method, using Alzheimer's drug, could revolutionise dental treatments


A new method of stimulating the renewal of living stem cells in tooth pulp using an Alzheimer’s drug has been discovered by a team of researchers at King’s College London.

Following trauma or an infection, the inner, soft pulp of a tooth can become exposed and infected. In order to protect the tooth from infection, a thin band of dentine is naturally produced and this seals the tooth pulp, but it is insufficient to effectively repair large cavities. Currently dentists use manmade cements or fillings, such as calcium and silicon-based products, to treat these larger cavities and fill holes in teeth. This cement remains in the tooth and fails to disintegrate, meaning that the normal mineral level of the tooth is never completely restored.

However, in a paper published today in Scientific Reports, scientists from the Dental Institute at King’s College London have proven a way to stimulate the stem cells contained in the pulp of the tooth and generate new dentine in large cavities, potentially reducing the need for fillings or cements.

The novel biological approach could see teeth use their natural ability to repair large cavities rather than using cements or fillings.

Significantly, one of the small molecules used by the team to stimulate the renewal of the stem cells included Tideglusib, which has previously been used in clinical trials to treat neurological disorders including Alzheimer’s disease.

Using biodegradable collagen sponges to deliver the treatment, the team applied low doses of small molecule glycogen synthase kinase (GSK-3) inhibitors to the tooth. They found that the sponge degraded over time and that new dentine replaced it, leading to complete, natural repair. Collagen sponges are commercially-available and clinicallyapproved, again adding to the potential of the treatment’s swift pick-up and use in dental clinics.

Outcry as Chinese school makes iPads compulsory
Apple products are incredibly popular in China, but not everyone can afford them 
A school in northern China has been criticised for enforcing iPad learning as part of its new curriculum, it's reported.
According to China Economic Daily, the Danfeng High School in Shaanxi province recently issued a notice saying that, “as part of a teaching requirement, students are required to bring their own iPad” when they start the new school year in September.
Staff told the paper that using an iPad would “improve classroom efficiency”, and that the school would managean internet firewall, so that parents would not have to worry about students using the device for other means.
However, China Economic Daily says that after criticism from parents, who felt that it would be an “unnecessary financial burden”, eadmaster Yao Hushan said that having an iPad was no longer a mandatory requirement. Mr Yao added that children who don't have a device could still enrol, but that he recommended students bring an iPad as part of a “process of promoting the digital classroom”.
The incident led to lively discussion on the Sina Weibo social media platform. “Those parents that can't afford one will have to sell a kidney!” one user quipped. 
Others expressed concerns about the health implications of long-term electronic device use. “I worry about their vision,” one user said, and another said they would all become “short-sighted and have to wear glasses.”
But others felt that it was a good move in line with new modern ways of teaching. “They are affordable for the average family, one said, “they don't necessarily need to buy the latest model.”
