Research Identifies Essential Energy Sources for Developing Carnivorous Larval Fish

Lipids are essential for fish because they supply energy, support cell structure, and help carry fat-soluble nutrients. This is especially important in carnivorous fish, which use carbohydrates less efficiently than many other animals.

High-Speed Microscope Captures Millisecond-Scale Brain Signaling Activity

Within the brain, neurons compute by generating electrical impulses. These signals travel throughout neurons, which are in turn connected in vast networks that control brain functions such as sensory perception, memory formation, and control of movement.

New Research Reveals Cellular Switches Driving Physical Adaptation in Marine Species

In the animal kingdom, only those who adapt to their environment will survive. This adaptation comes in a wide range of forms, from invisible internal shifts in gene expression to dramatic anatomical changes, such as tadpoles growing legs and transitioning to life on land as frogs.

Living Organisms Depend on Bacterial Production of Critical Vitamin B12

All living organisms need a little bit of it to form red blood cells and DNA, as well as to build and support brain and nerve cells. But it's hard to come by: Humans don't make it. Animals don't make it. Plants don't make it.

Moth Wings Smell Host Plants to Identify Optimal Egg-Laying Spots

Insect wings are bristling with senses, feeling the wind blowing and even tasting potential mates, but little was known about whether moth wings are equipped with a sense of smell.

New Study Shows Larval Honey Bees Rely Entirely on Taste Rather Than Olfaction

Honey bee larvae lack the sophisticated olfactory capabilities of adult honey bees, a new study finds. Scientists point to this temporary loss-of-function as a side effect of the nurse bees' heroic level of brood care, calling it a consequence of social evolution.

Novel Study Reveals Hidden Biological Drivers Behind Cancer Induced Appetite Loss

Cachexia is a condition in which patients affected by cancer or other chronic diseases become sick and lose weight. The condition often involves brain-related symptoms of sickness, such as loss of appetite, which can lead to loss of muscle and often fat.

Study Reveals Common Brain Processing Rules Across Diverse Species

Line up the brains of a fish, bird and a mammal, and something unexpected comes up. You do not see three different answers to the problem of making sense of the world. You see one answer, tilted three different ways.

Three Hundred Million Year Old Fish Brain Overturns Paleontology Assumptions

Over 300 million years ago, a minnow-sized fish died and fell to the bottom of the prehistoric swamp near the village of Trawden, Lancashire, in northwest England.

Using Environmental DNA to Monitor Global Riverine Biodiversity

A global analysis of fish biodiversity using environmental DNA (eDNA) reveals how human activity and climate influence biodiversity patterns in river ecosystems.

Early Visual Experiences Reshape the Retina and Change Behavior

King's College London neuroscientists examined the fish over the first five days of their lives to see if the visual characteristics of their upbringing had an impact on the development of the eye's cells.

Modified Mediterranean Diet Improves Lifespan and Metabolic Health

A plant- and fish-based, low-protein diet paired with small amounts of an amino acid commonly found in eggs, meat and dairy increased healthy lifespan and decreased frailty and fat mass in mice, according to a new USC study published today in the journal Cell Metabolism.
