Ōtākou Whakaihu Waka research shows Aotearoa has been increasingly accepting new bird species from around the world since the start of the Ice Age, offering clues into future migration patterns. Since the Ice Age drastically changed the Aotearoa landscape from widely forested to grass and shrubland, researchers set out to determine which of our living and recently extinct birds are a result of existing lineages that adapted to their environment tens of millions of years ago and which are the…

Globally, women’s workforce participation is about 25% lower than men’s, often due to barriers such as domestic responsibilities and cultural norms. Vocational training can increase employment opportunities, but women may not be able to attend training programs that require them to be away from home. A new study from the University of Illinois Urbana-Champaign, in collaboration with an international research team, explored whether hybrid distance learning can improve accessibility to job training for rural women in Nepal. “We had been working in…

Researchers at the RIKEN Center for Brain Science (CBS) have uncovered how perceptual memories linked to positive emotions, such as joy or happiness, are strengthened during sleep. The study, published in the scientific journal Neuron, could help scientists understand the neurological basis for overcoming conditions like drug or sexual addiction. Why do emotional events, whether positive or negative, create strong, long-lasting memories of external information such as music, scene smells and textures received at the events? We know that sleep is…

For the first time, DNA evidence has confirmed killer whales in Australia hunted a white shark for its liver. Based on DNA analysis from the bite wounds on the carcass of a large white shark washed ashore near Portland in Victoria in 2023, the Flinders University-led study identified that killer whales were responsible for consuming the mid-section containing the nutritionally rich liver. Around the world, killer whales (Orcinus orca) have been observed preying on various shark species including white sharks…
