Japanese scientists reverse Alzheimer’s synapse damage in mice

Scientists from the Okinawa Institute of Science and Technology say they have reversed the signs of Alzheimer’s disease in lab mice by restoring the healthy function of synapses, critical parts of neurons that shoot chemical messages to other neurons. If the treatment successfully survives the gauntlet of clinical studies with human participants, it could potentially lead to a groundbreaking new treatment for humans suffering from the deadly disease.

Wooden satellite

Japanese scientists build world’s first wooden satellite

The satellite dubbed LignoSat, a collaboration between Kyoto University and the company Sumitomo Forestry, is reportedly slated for launch in September onboard a SpaceX rocket. If successful, the tiny device — just four inches on each side — could represent a major breakthrough in space sustainability efforts. The idea is that it’ll burn up entirely upon reentry, vastly reducing its environmental impact compared to traditional metal spacecraft.

Coal pollution

G7 agree to close all coal-fired generating stations by 2035

Energy ministers from the G7 countries — Canada, France, Germany, Italy, Japan, the United Kingdom, the United States, and the European Union — agreed at a meeting in Turin, Italy, to close all coal-fired generating stations in their countries by 2035 if not sooner. Putting an end date on coal — the most polluting of all fossil fuels — has been highly controversial at international climate talks. Until this point, Japan, which derived 32% of its electricity from coal in 2023 according to the climate advocate Ember, has blocked progress on the issue at past G7 meetings.

Japanese high court rules same-sex marriage ban unconstitutional

Japan’s march toward marriage equality took a giant leap when a high court ruled the country’s ban on same-sex marriage is unconstitutional. Civil code rules limiting marriage to couples of the opposite sex, the high court in Sapporo ruled, are “unconstitutional” and “discriminatory.” Existing law, the justices wrote, should be revised or rewritten to include other types of unions in addition to those between a man and a woman.

In its decision, the court said that the requirement forces trans people to make the “cruel choice between accepting the sterilization surgery that causes intense bodily invasion and giving up important legal benefits of being treated according to their gender identity.”
