Why reading nursery rhymes and singing to babies may help them to learn language
Phonetic information -- the smallest sound elements of speech -- may not be the basis of language learning in babies as previously thought. Babies don't begin to process phonetic information reliably until seven months old -- which researchers say is too late to form the foundation of language. Instead, babies learn from rhythmic information -- the changing emphasis of syllables in speech -- which unlike phonetic information, can be heard in the womb.

Climate: Why disinformation is so persistent
Melting of glaciers, rising sea levels, extreme heat waves: the consequences of climate change are more visible than ever, and the scientific community has confirmed that humans are responsible. Yet studies show that a third of the population still doubts or disputes these facts. The cause is disinformation spread by certain vested interests. To try and prevent this phenomenon, a team has developed and tested six psychological interventions on nearly 7,000 participants from twelve countries. The research highlights the extremely persuasive nature of disinformation and the need to strengthen our efforts to combat it.

Scientists create framework to guide development and assessment of urban climate action plans
With the world projected to be highly urbanized by 2050, cities are encouraged to take urgent climate actions to mitigate and adapt to the threats of climate change. As climate change intensifies and urbanization increases rapidly, local governments are expected now more than ever to lead climate action planning. However, studies show the limitations of the existing climate action plans (CAPs). So scientists have created an Urban Climate Action Planning (UCAP) framework to guide the development of suitable urban CAPs and support the assessment of the level of suitability of these plans.

Half of tested caviar products from Europe are illegal, and some aren't even caviar
Wild caviar, a pricey delicacy made from sturgeon eggs, has been illegal for decades since poaching brought the fish to the brink of extinction. Today, legal, internationally tradeable caviar can only come from farmed sturgeon, and there are strict regulations in place to help protect the species. However, by conducting genetic and isotope analyses on caviar samples from Bulgaria, Romania, Serbia, and Ukraine -- nations bordering the remaining wild sturgeon populations -- a team of sturgeon experts found evidence that these regulations are actively being broken. Their results show that half of the commercial caviar products they sampled are illegal, and some don't even contain any trace of sturgeon.

New global stocktake: Healthy forests could store much more carbon
Natural carbon reservoirs will play a major role at the COP28 world climate conference in the United Arab Emirates. In a recent study, a team of more than two hundred researchers worldwide presents new estimates of the storage potential of forests around the globe. According to the study, forests could ideally absorb 328 billion tons (gigatons, Gt for short) of carbon. However, as many formerly forested areas are now used for agriculture and as settlement areas, the potential is reduced to 226 Gt. 139 Gt of this (61%) could be achieved by protecting existing forests alone. The remaining 87 Gt (39%) could be realized by reconnecting previously fragmented forest landscapes and managing them sustainably.
