REVERSING DIABETES
Half a billion people worldwide live with diabetes. There are different types with different causes, but all lead people to have too much sugar in their blood. If not well controlled, this excess glucose can inflict damage throughout the body, putting people at risk of gum disease, nerve damage, kidney disease, blindness, amputations, heart attack, stroke and cancer.
For now, patients manage the condition with medicines, insulin and lifestyle changes, but a new generation of treatments could reverse the disease. Details of the first woman treated for type 1 diabetes with stem cells taken from her own body were announced last month. Beforehand, the 25-year-old needed substantial amounts of insulin. Now she produces her own.

In April, a similar cell transplant allowed a 59-year-old man with type 2 diabetes to come off insulin. It’s early days and challenges remain, not least around scaling the treatment, but the results so far are exciting.

CANCER VACCINES

Vaccines were one of the remarkable success stories of the pandemic. Now scientists hope the same mRNA technology that underpinned the Moderna and Pfizer-BioNTech COVID-19 jabs can be used to train the immune system to recognize and attack cancer.
These jabs work by providing an instruction to the patient’s cells to churn out a particular protein that acts as a flag for the immune system to target. In this case, scientists are tailoring the vaccine design to proteins on the surface of a patient’s cancer cells.
In August, hundreds of patients entered the world’s first personalized mRNA cancer vaccine trial for melanoma and trials are under way for pancreatic, bowel and other cancers. And since the protection afforded by vaccines can be long-lasting, it may be possible to use the approach as a preventive measure, for those with high genetic risk of breast or ovarian cancer, and to stop cancer returning.

AI AND CANCER
The next four years are set to see rapid progress in the use of artificial intelligence to better diagnose serious illnesses like lung cancers and brain tumors, which should mean longer lives.
The tech is being rolled out in hospitals, including several in the north of England, to catch cancers quicker and prolong lives. The system, which scans x-rays and prioritizes cases where it spots something suspicious that the human clinician may have missed, has been shown to improve diagnostic accuracy by 45 percent and diagnostic efficiency by 12 percent, according to the South Tyneside and Sunderland NHS Foundation Trust.

OUTER SPACE
In the two years since its launch, the James Webb space telescope has revealed the night sky in a series of images that are technicolor masterpieces. It is also enabling unprecedented discoveries about the origins of stars, black holes, the evolution of the universe and the likelihood of life existing elsewhere in the cosmos.
The telescope is so powerful that it has observed galaxies that existed when the universe was less than 300 million years old, whose light has traveled for 14 billion years, almost the age of the universe itself, to reach us. Capturing light from the first stars to light up the sky, long viewed as a holy grail in astronomy, now appears within reach. Some of these discoveries are upending conventional theories, with the earliest galaxies appearing far brighter or bigger than expected and the first blackholes appearing to have snowballed more quickly than can be explained by current models.
In science, weird and unexpected findings are not viewed with disappointment — they are the fuel that powers the next revolution. This telescope promises to do just that for our understanding of the history of the universe and whether we humans are alone in it.

RENEWABLE ENERGY
The world’s transition to green energy is gaining pace. A recent report by the International Energy Agency (IEA), the world’s energy watchdog, found that over the next six years renewable energy projects are on track to roll out at three times the pace of the previous six years. This would put the world on course to outpace the 2030 goals set by governments to create a total global renewable energy capacity roughly equal to the existing power systems in China, the EU, India and the US combined.
In Europe, the boom in solar power caused market prices to turn negative for a record number of hours this summer. Wind developers are preparing to launch a new generation of floating offshore wind turbines to better capture the more powerful wind speeds further from the shore.
The green electricity surge will be led by the clean energy programs of China and India, which would help to displace the fossil fuel consumption of two of the most polluting countries in the world.
China will have more than half of the world’s renewables by the end of the decade, according to the IEA, which is already thought to have slowed China’s pipeline of future coal power plants. The number of new permits for coal plants in China has fallen from 100GW in 2022 and last year to only 12 new projects totaling 9.1GW in the first half of this year, according to Global Energy Monitor.

Nov. 11 to Nov. 17 People may call Taipei a “living hell for pedestrians,” but back in the 1960s and 1970s, citizens were even discouraged from crossing major roads on foot. And there weren’t crosswalks or pedestrian signals at busy intersections. A 1978 editorial in the China Times (中國時報) reflected the government’s car-centric attitude: “Pedestrians too often risk their lives to compete with vehicles over road use instead of using an overpass. If they get hit by a car, who can they blame?” Taipei’s car traffic was growing exponentially during the 1960s, and along with it the frequency of accidents. The policy
Hourglass-shaped sex toys casually glide along a conveyor belt through an airy new store in Tokyo, the latest attempt by Japanese manufacturer Tenga to sell adult products without the shame that is often attached. At first glance it’s not even obvious that the sleek, colorful products on display are Japan’s favorite sex toys for men, but the store has drawn a stream of couples and tourists since opening this year. “Its openness surprised me,” said customer Masafumi Kawasaki, 45, “and made me a bit embarrassed that I’d had a ‘naughty’ image” of the company. I might have thought this was some kind
What first caught my eye when I entered the 921 Earthquake Museum was a yellow band running at an angle across the floor toward a pile of exposed soil. This marks the line where, in the early morning hours of Sept. 21, 1999, a massive magnitude 7.3 earthquake raised the earth over two meters along one side of the Chelungpu Fault (車籠埔斷層). The museum’s first gallery, named after this fault, takes visitors on a journey along its length, from the spot right in front of them, where the uplift is visible in the exposed soil, all the way to the farthest
The room glows vibrant pink, the floor flooded with hundreds of tiny pink marbles. As I approach the two chairs and a plush baroque sofa of matching fuchsia, what at first appears to be a scene of domestic bliss reveals itself to be anything but as gnarled metal nails and sharp spikes protrude from the cushions. An eerie cutout of a woman recoils into the armrest. This mixed-media installation captures generations of female anguish in Yun Suknam’s native South Korea, reflecting her observations and lived experience of the subjugated and serviceable housewife. The marbles are the mother’s sweat and tears,
