Is the Immune System to Blame for Schizophrenia?
The Literature

Distracted Brains Better at Parsing Unfamiliar Languages: Study
People who had cognitive functions depleted by noninvasive brain stimulation or a mentally demanding task could subconsciously recognize individual words in a made-up language more easily than controls, researchers find.

SARS-CoV-2 Can Spread Via Cell-to-Cell Transmission
The virus’s ability to slip directly from one cell to another may help it avoid some of the body’s immune responses.

Dozens of Genes Tied to Caribou’s Seasonal Migration
Researchers tracked the movements of endangered caribou and sequenced a portion of their genomes to determine which genes may influence migratory behavior.

Surface Area of Tooth Roots Predicts Primate Body Size
Researchers determine that a primate’s tooth root, and not just its crown, can yield reliable information about body size, but the relationship between root surface area and diet isn’t as clear.

Salmonella Injection Helps the Mouse Immune System Kill Tumors
Nanoparticle-coated bacteria can capture tumor antigens and deliver them to immune cells, triggering a response that improved survival rates in mice.

Infographic: Questions Linger About Epigenetic Inheritance
Some studies suggest that associations between the health of children and the experiences of their parents or grandparents may be due to epigenetic mechanisms, but confounding factors challenge this interpretation.

Infographic: How the Body’s Defenses Attack the Brain
Scientists have pinpointed several pathways through which the immune system could disrupt neuronal functioning and thereby lead to psychotic symptoms.

Infographic: Simultaneously Studying Neuron Structure and Function
A new methodology combines existing techniques to reveal the specific function and location of multiple types of neurons at once.

Infographic: Mixed Evidence on Human Occupation of the Americas
Diverse lines of evidence point to humans’ presence in the New World long before the dawn of Clovis culture. But rewriting this chapter of human history raises many questions about how these early people came to inhabit these continents.

Infographic: Short Protein Motifs’ Role in SARS-CoV-2 Infection
Known as SLiMs, these stretches of up to 10 amino acids play notable roles in cell biology, including responses to viral invasion.

Infographic: Salmonella Shuttle Tumor Antigens to Immune Cells
Nanoparticle-coated bacteria carry cancer-derived proteins to dendritic cells, enabling the immune system to launch a response in a mouse model.

Dwarf Mongooses Shun Bullies to Manage Conflict: Study
These social animals keep tabs on aggressive members of the group and groom them less after fights to punish them.

Unearthing the Evolutionary Origins of Insect Wings
A handful of new studies moves the needle toward a consensus on the long-disputed question of whether insect wings evolved from legs or from the body wall, but the devil is in the details.

Fish Are Chattier Than Previously Thought
Once thought to be silent, fish turn out to produce a range of vocalizations—so polluting the oceans with noise could pose a danger to them.

The Mystery of the Mouse Sperm Hook
Nearly all mouse sperm have hooks on their heads. But new research suggests the structures slow them down—so what exactly is their purpose?
