South Korean Scientists Develop Cancer Treatment with LED

South Korean scientists have developed a new technology to diagnose and treat cancer by using light-emitting diodes (LEDs) and laparoscopy, a state-run institute has said.

The Korea Electrotechnology Research Institute (KERI) said it has developed a technology that can target tumor cells and it is in the process of transferring the related knowhow to a local company, the South Korean News Agency, Yonhap, reported.

Recently, minimally invasive treatment and diagnostic methods, such as photodynamic therapy (PDT) and laparoscopy, have gained ground as methods that greatly improve the quality of patients' lives.

PDT is a treatment that uses drugs called photosensitizing agents to "activate" certain kinds of light to help facilitate treatment. It is effective since the light only targets cancerous growth and not normal cells, according to Yonhap.

Officials explained that the technology developed by the government-run institute is a development of the process of using LED light to detect cancer cells, as well as utilizing a PDT laser designed to treat cancer based on laparoscopy technology, the German News Agency reported.

Japan has recorded its warmest autumn since records began 126 years ago, the weather agency said, delaying the country's popular displays of seasonal foliage into December.

"This year was 1.97 degrees Celsius higher than usual... making it the hottest autumn since 1898, when statistics began," the Japan Meteorological Agency said Monday on their website.

Between September and November, the temperature was 2.4 degrees Celsius higher than usual in Tokyo, 2.9 more in the central city of Nagoya and 1.2 warmer in northern Sapporo city.

The weather has delayed the country's autumn foliage season -- when tourists flock to see leaves turn vibrant reds and yellows.

In Kyoto, a railway company known for running trains through forests of illuminated maple trees at night has extended its schedule because leaf colors are not changing as quickly as usual.

According to the Japan Meteorological Corporation, the best time to see the autumn leaves in Tokyo is around December 5 and in Osaka on December 9, both later than usual.

Japan recorded its joint-hottest summer on record this year as extreme heatwaves, which scientists say are fueled by climate change, engulfed many parts of the world.

The famous snowcap of Mount Fuji was absent for the longest recorded period this year, not appearing until early November, compared with the average of early October.

Climate scientists forecast that 2024 will almost certainly be the hottest year on record.

Australia has meanwhile sweltered through its warmest spring on record, the country's weather bureau said Sunday, with temperatures 2.08 degrees Celsius above the average.

Australia's previous hottest spring -- running between September and November in the Southern Hemisphere -- was recorded in 2020.
