Compare shark sizes on our infographic
Since Jaws was released 50 years ago, great white sharks have, arguably, become the most recognized fish in the ocean. But despite their fame, they’re not the biggest shark species.…
This moth species may use the Milky Way as its guiding star
One kind of Australian moth looks to the stars on its voyage to a summertime refuge. Stellar cues from the Milky Way’s bright band may help Bogong moths (Agrotis infusa)…
3D-Printed Brain Model Mimics Neural Damage
Summary: Researchers have developed a groundbreaking 3D brain model that closely mirrors the architecture and function of the human brain. Built using biomimetic 3D printing, the Bioengineered Neural Network (BENN)…
Low Sodium Linked to Anxiety Through Brain Chemistry Disruption
Summary: Chronic hyponatremia—long viewed as symptomless—is now shown to disrupt brain chemistry and cause anxiety-like behaviors, according to a new study in mice. Researchers found that prolonged low sodium levels…
Neglecting Dads’ Mental Health May Harm Kids’ Development
Summary: Experts urge healthcare providers to screen new fathers for mental distress, citing strong evidence that paternal mental health affects child development. Depression, anxiety, and stress in new dads are…
Fewer scavengers could mean more zoonotic disease
Scavengers often get a bad rap — hyena giggles are nefarious, crows gather in “murders” and the naked necks of vultures speak for themselves. But the bodies of the dead…
Viewpoint: Controversy heats up over ‘informed consent’ for trans-identifying teenagers seeking a sex change operation
In the U.S., the mainstream medical (and legal) community strongly supports gender-affirming care for young people. Most American doctors “maintain… that “gender-affirming care is essential, life-saving medical treatment that supports individuals…
Brain Adapts to Neuron Loss Through Rapid Rewiring
Summary: New research shows that the brain’s cortex can rapidly reorganize itself after losing neurons, allowing other nerve cells to take over lost functions. Scientists studied neural networks in the…
Different Autism Genes, Same Brain Signature
Summary: New research shows that different genetic forms of autism may produce a shared brain activity pattern, revealing a potential common neural signature despite distinct genetic origins. Using brain-wide recordings…
