What birds can teach us about social learning
New link between a brain region and how zebra finches learn their birdsongs by imitating other zebra finches.

(Press-News.org) How does a bird learn its birdsong? Tomoko Fujii and Masashi Tanaka, from Waseda University, explored what drives a zebra finch to approach and imitate other zebra finches to learn its birdsong in a new JNeurosci paper.
The researchers explored song learning in young male zebra finches as they interacted with “tutor” adults that already knew their birdsongs. Young zebra finches preferably approached tutors that sang longer but less frequently. Fujii and Tanaka next probed the role of a brain region traditionally linked to emotions in mammals (the amygdala) in this song-learning process. To examine the role of the amygdala, the researchers removed it from the young zebra finches. While loss of this brain region did not hinder song imitation, tutor selection became more unpredictable as birds pursued tutors less discerningly. Tracing neural connections in the zebra finch brain further confirmed that the amygdala doesn’t necessarily drive song control and learning, but may play a role in socially selective, imitative behavior, according to the authors.

Background and objectives
Lung Squamous cell carcinoma (LSCC) represents the second most common non-small cell lung cancer. Although studies identified adenocarcinoma-like driver mutations in LSCC using next-generation sequencing (NGS), the disease is challenging to treat due to the limited number of detectable mutations for targeted drug therapy. This study aimed to evaluate the mutation profiles of LSCC detected by NGS to assess the relationships between different driver mutations and clinicopathological parameters.
Methods
NGS ...

FRANKFURT. Otodus megalodon was the largest predatory fish in Earth’s history: Measuring up to 24 meters, it was longer than a truck with a trailer and weighed almost twice as much. Embedded in its jaws were triangular teeth the size of a hand, and its bite had the force of an industrial hydraulic press. It swam through the world’s oceans between 20 and 3 million years ago, frequently on the hunt for prey to satisfy a calorie demand as vast as its size: According to estimates, it required around 100,000 kilocalories per day. Science widely assumed that megalodon’s main calorie intake was in the form of ...

Toronto, ON – Climate change and extreme weather events are threatening the sexual and reproductive health (SRH) of young adolescents in Kenya, according to a new study published earlier this month in BMJ Global Health. The study reveals that food, water, and sanitation insecurities are placing young adolescents aged 10-14, especially girls, at increased risk of school dropout, transactional sex, gender-based violence, and early pregnancy.

Males are more than four times more likely to receive an autism diagnosis than females. But a new study by researchers at UC San Diego School of Medicine has found no clinical differences in autistic traits between the sexes in toddlers when they are first diagnosed with autism. The study was published in Nature Human Behavior on May 26, 2025. The findings have potential implications for early diagnosis and intervention for autistic children.
Between 2002 and 2022, the researchers assessed more than 2,500 male and female toddlers between 12 and 48 months of age. Of these toddlers, 1,500 were ...

Africa's predominantly rainfed agricultural sector is highly vulnerable to erratic rainfall and the impacts of climate change. Despite having significant irrigation potential, only a small fraction of Africa’s arable land is currently equipped for irrigation. A new policy brief by the United Nations University Institute for Water, Environment and Health (UNU-INWEH) - Implementing the IDAWM Framework to Enhance Agricultural Water Management in the African Union – developed in collaboration with Centre on Climate Change & Planetary Health of London School of Hygiene and Tropical Medicine, International ...

A new guideline to diagnose and treat hypertension is aimed at helping primary care clinicians, including family physicians, nurses, nurse practitioners, and pharmacists, manage the disease. The new guideline, the first of 2 from Hypertension Canada, is published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.241770, and will be republished with permission in Canadian Family Physician and Canadian Pharmacists Journal, with a summary in Canadian Nurse.
Hypertension is the most common modifiable risk factor for heart disease and death, affecting about 1 in 4 adults in Canada. Canada has been a ...

Milan, Italy: A new, rapid testing method will greatly help the diagnosis of rare diseases in babies and children, according to research to be presented to the annual conference of the European Society of Human Genetics today (Monday). While rare genetic diseases are uncommon, as their name suggests, there are more than 7,000 types of disease caused by mutations in more than 5,000 known genes, affecting approximately 300 million individuals worldwide. Currently about half of all patients with a suspected rare disease remain undiagnosed and existing testing methods for undiagnosed conditions are typically slow, ...

Milan, Italy: Neuropathy, a disorder in which damage to nerves can impair sensation and movement, has many causes, including infection1. Now, researchers from the UK have identified distinct genetic changes in a newly-discovered neuropathy and believe that their work will provide insights into the causal mechanism and why some previously healthy people develop neuropathies after infection whereas others do not.
Dr Rob Harkness, a postdoctoral research Fellow at the University of Manchester, Manchester, UK, will tell the annual ...

In recent years, the concept of "rewilding" has risen to prominence in the conservation community, but to date, most efforts have been concentrated on large protected areas far from cities—and consequently, far from urban areas suffering pronounced biodiversity losses. In a recently published BioScience article, Patrick Finnerty (University of Sydney) and colleagues make the case for "urban rewilding" as a vital approach for addressing biodiversity losses, focusing on the rapidly expanding cities that are soon expected to be home to ...

A gene that regulates the development of roots in vascular plants is also involved in the organ development of liverworts — land plants so old they don’t even have proper roots. The Kobe University discovery highlights the fundamental evolutionary dynamic of co-opting, evolving a mechanism first and adopting it for a different purpose later.
When scientists discover that a gene is necessary for the development of a trait, they are quick to ask since when this gene has been involved in this and how the evolution of the gene has ...
