December 31 The new 2023 World Health Organization report on road safety shows that, since 2010, road traffic deaths have fallen by 5%—and that would translate into a 16% drop if the rise in global population was accounted for. 108 countries reported a drop in road traffic-related deaths between 2010 and 2021. Ten countries succeeded in reducing road traffic deaths by over 50%.

December 29 Violent crime across America fell at one of the fastest rates ever recorded in 2023, offering a meaningful reversal after the pandemic years pushed homicides to historic highs. The drop touched cities of nearly every size — from large metros like Los Angeles and Chicago to suburban and rural counties alike. Analysts were surprised by both the speed and the breadth of the turnaround. Progress like this shows that even deeply entrenched crime surges...

December 29 Saiga antelope have made one of the most dramatic wildlife recoveries on record, with populations in Kazakhstan climbing nearly 40-fold over two decades. That rebound reflects years of cross-border coordination between governments, research institutes, and NGOs — the kind of sustained collaboration that rarely gets headlines but quietly saves species. The recovery remains fragile, however; disease outbreaks and persistent poaching pressure still pose serious threats. Even so, the saiga's return offers a genuinely hopeful...

December 29 The number of electric school buses operating or delivered in the U.S. rose from 598 in March 2022 to 1,285 in June 2023. The number of electric school buses that have been ordered or awarded funding nearly tripled in the same period. Forty-nine states had electric school bus commitments as of June 2023.

December 28 According to the East Asian nation's Environment Ministry’s new biogas law, public and private industries that generate organic waste such as livestock manure and food waste will now be required to produce them in the form of biogas. Biogas is a gaseous renewable energy source produced from raw materials such as agricultural waste, plant material and manure and can be used in vehicles that operate on natural gas.

December 28 A new study from Australia's Murdoch University evaluating the effectiveness of an eight-week program focusing on self-compassion and mindfulness found that it reduced symptoms of post-traumatic stress and improved quality of life and connectivity in parts of the brain that regulate emotions.

December 28 Sodium-ion EVs just hit the road for the first time, with Chinese automaker JAC delivering its Yiwei hatchback to customers in January 2024 — the world's first mass-produced electric car running on a battery made from one of Earth's most abundant elements. The little urban hatchback offers about 157 miles per charge, plenty for daily commutes, and holds up better than lithium in cold weather. Because sodium is found in ordinary salt and spread...

December 27 Nuclear fusion just cleared a crucial bar: scientists at California's Lawrence Livermore National Laboratory have now achieved ignition four separate times, with the best shot producing 89 percent more energy than the lasers delivered to the target. That repetition is what transforms a single 2022 breakthrough into real, replicable science — proof that the Sun-like reaction can be coaxed out of a frozen hydrogen pellet on Earth, again and again. Momentum is building beyond...

December 27 Uruguay now generates between 90% and 98% of its electricity from renewables, a shift it pulled off in roughly 15 years after starting out almost entirely dependent on imported oil. The turning point came in 2008, when an oil price spike pushed the government to take a chance on a nuclear physicist with an unconventional pitch: skip the nuclear plant, go all in on wind. About 50 wind farms later, paired with existing hydropower,...

December 22 The sweeping pardon applies to all U.S. citizens and lawful permanent residents in possession of marijuana for their personal use and those convicted of similar federal crimes. It also forgives pot users in the District of Columbia.
