New Computational Tool Resolves Evolutionary Paradox of Genome Expansion

A genome contains all of the DNA of every living organism, but its contents don't stop there – most of these structures also contain snippets of DNA that can copy and paste themselves to "infect" a genome, expanding its size. Precisely why that happens remains a mystery.

Historic Victory for Koalas as Great Koala National Park Legislation Passes NSW Parliament

Conservation groups across New South Wales are celebrating a historic milestone for nature, with legislation to establish the Great Koala National Park passing after more than a decade of campaigning.

Stay Sharp After Menopause: How Aerobic Exercise Can Improve Key Thinking Skills

Regular aerobic exercise – the kind that gets your heart pumping – can improve important thinking skills called executive functions, and the benefits appear especially strong for women after menopause, according to Rutgers researchers.

Advanced RNA Sequencing Separates Rare Regenerative Cells From Mature Tissue

Researchers at Weill Cornell Medicine and Hospital for Special Surgery have discovered the unspecialized stem cells that give rise to the body's tendons and ligaments, the tissues connecting muscles and bones.

New Research: Greenland’s Smallest Animals are Changing with the Climate

Researchers at Aalborg University, Denmark, have spent several years studying insects in Greenland.

Colorectal Cancer and Nerve Damage: A Hidden Link Uncovered in Mice and Primates

Colorectal tumors trigger inflammatory nerve damage, suggesting cancer itself may be a risk factor for neuropathy in survivors, independent of treatments.

New Gene-Expression Based Clocks Better Predict Age-Related Disease and Mortality

What do "epigenetic clocks" actually measure? These lab tests have become popular tools for studying biological aging, or how the body's cellular function changes at a faster or slower rate than expected.

New Single-Cell Database Reveals Hidden Inner Workings of Spinal Cord Circuits

Scientists at St. Jude Children's Research Hospital created a single-cell atlas of a key class of spinal neurons involved in motor coordination. From that resource, they identified a small subgroup of interneurons associated with the speed of rhythmic movements such as walking. The findings, which have implications for understanding spinal cord function and recovery from injury, were published today in Nature Communications.

Study Reveals How Fruit Flies Navigate Odor Plumes Using Directional Memory

When a fruit fly catches a whiff of a ripe peach, it quickly heads toward it. Time after time, it finds the fruit-even from many feet away and even if the scent arrives only as a few drifting, disconnected puffs.

New Kinesin-1 Protein Maps Advance Treatment for Incurable Paralysis

A nerve cell resembles a vast tree with branches that communicate with thousands of other cells.

Rapid Wound Healing in Jellyfish Offers Insights Into How Human Skin Repairs

Jocelyn Malamy first witnessed jellyfish cells "walk" toward each other to close a wound at the Marine Biological Laboratory a decade ago.

EPFL Study Reveals Mice Actively Seek Better Visual Infotaxis

Animals don't experience the world passively. A hawk tilts its head to track prey. A person leans forward to read a sign. Scientists call this "active sensing": moving the body to gather better information.

Researchers Develop Non-Toxic Way to Generate the Symptoms of Parkinson's Disease

Scientists usually use animal models when studying Parkinson's disease because these models mimic the disease well.

Study Reveals Major Body Size Jump Within the Genus Homo

The biggest jump in body size among our ancestors happened around 2 to 2.5 million years ago, with the appearance of Homo rudolfensis or Homo erectus/ergaster, rather than gradually across the whole human family tree.

Study Shows Protein Fragment Reduces Neuronal Degeneration in Mice

Researchers at the Federal University of São Paulo (UNIFESP) in Brazil have discovered a new strategy that may protect neurons and other brain cells involved in Parkinson's disease in the future.

New Open Access Connectome Unveils Intricate Fruit Fly Neural Connections

In a first, a large, international team led by multiple labs at Harvard Medical School and Princeton University has published a complete wiring diagram of all the connections between neurons in the central nervous system of an adult fruit fly.

Genetic Study Reveals Biological Drivers of Frailty in Aging

Researchers at McMaster University have identified, for the first time, a novel region of DNA and two associated genes connected to frailty, offering neurological and immune-related insights that might help explain why some older adults are more likely to be frail than others.

New Bioelectronic Scaffold Captures Coordinated Brain-Like Activity in 3D Tissues

A team led by Northwestern University and Shirley Ryan AbilityLab scientists have developed a new technology that can eavesdrop on the hidden electrical dialogues unfolding inside miniature, lab-grown human brain-like tissues.

Bacteria Use One Simple Strategy to Navigate Complex Worlds

Just like every other creature, bacteria have evolved creative ways of getting around. Sometimes this is easy, like swimming in open water, but navigating more confined spaces poses different challenges.
