A study of 1,737 climate policies across 40 countries over 32 years shows which measures consistently reduce emissions regardless of context. Carbon taxes and investments in renewable energy and research stand out as particularly reliable instruments for reducing emissions.
The number of people killed in terrorism dropped by 28 percent globally in 2025, to a total of 5,582. The number of terrorist attacks decreased by 22 percent, to 2,944 incidents. These are the lowest figures recorded since 2007.
Researchers at CSIRO have created a working prototype quantum battery that charges wirelessly with a laser and completes a full battery cycle: charging, storing, and discharging energy. Unlike conventional batteries, quantum batteries charge faster the larger they are.
Mortality among children under five has fallen by approximately 60 percent since 1990, thanks to investments in vaccinations, newborn care and nutrition. Mortality among newborns has decreased by 45 percent during the same period.
If all countries managed their waste the way high-income countries do today, global plastic pollution would decrease by over 98 percent. Every dollar invested in waste management in low-income countries prevents about 25,000 times more plastic pollution than the same dollar spent in a rich country.
NASA's deliberate space collision with the asteroid Dimorphos shifted the asteroid pair's orbit around the sun. It is the first time scientists have been able to measure such a change, confirming that the technique works for deflecting dangerous asteroids.
The share of children living in families with a low income standard has fallen from 10 percent to 6 percent since 2014. 56 percent of all children live in families with a high income standard, that corresponds to more than 1.2 million children.
A study with 968 participants shows that personalized feedback from an AI coach makes people significantly better at communicating with empathy. People who feel empathy often fail to express it โ most believed they were good listeners, but independent assessment showed that few actually were.
44 percent of Swedes have high or fairly high trust in journalists, according to the latest survey from the SOM Institute. The share has risen from 24 percent in 2004, nearly doubling over two decades. At the same time, the share who think journalists do their job poorly has been cut in half.
