Eriophyidae

Eriophyidae, gall mites, are the largest family of eriophyoid mites: about 200 µm long, four-legged, plant-feeding pests that induce galls, with roughly 3,790 described species and high host specificity.

Eriophyoidea

Eriophyoidea, gall mites or four-legged mites, is a superfamily of tiny (about 200 μm) worm-like plant-feeding acariform mites with two pairs of legs, over 5000 species in three families, major crop pests and virus vectors, likely sister to Nematalycidae.

Eriosyce curvispina

Eriosyce curvispina, also placed as Neoporteria or Horridocactus curvispinus, is a globular cactus endemic to central Chile. A 2024 molecular revision split the broad species complex into nine endemic species and assessed E. curvispina as Vulnerable.

Eristalinae

Eristalinae is the largest subfamily of hoverflies (Syrphidae), with nine tribes including Eristalini and Milesiini; known for rat-tailed maggots and bee or wasp mimicry, but molecular data show it is paraphyletic.

Eristalis

Eristalis (drone flies) is a genus of about 100 Holarctic hoverflies (Syrphidae) whose larvae are rat-tailed maggots; Eristalis tenax, the drone fly, is a honeybee-mimicking pollinator now reared commercially.

Eristalis tenax

Eristalis tenax, the drone fly (larva: rat-tailed maggot), is a hover fly that mimics the honey bee; its aquatic larva breathes through a siphon up to 15 cm long and lives in sewage-rich water.

Erithacus

Erithacus is a genus of Muscicapidae songbirds erected by Cuvier in 1800, holding the European Robin (E. rubecula) and, in ITIS, the Japanese and Ryukyu Robins; a 2022 study split Canary Islands robins into E. superbus and E. marionae.

Eritoran

Eritoran (E5564) is a synthetic lipid A analog and TLR4 antagonist that binds the MD-2 hydrophobic pocket; developed by Eisai for severe sepsis, it was safe but failed to reduce mortality in phase 2 and phase 3 ACCESS trials.

Erkki Ruoslahti

Erkki Ruoslahti, born 1940 in Imatra, Finland, is a cancer biologist who co-discovered fibronectin, discovered the RGD cell attachment sequence, helped isolate integrins, and won the 2022 Lasker Award.

Erling Seeberg

Erling Christen Seeberg (1946–2004) was a biochemist whose 1970s work showed that three uvr gene products cut ultraviolet-damaged DNA in E. coli, cited in the 2015 Nobel Prize background.

Ermias Kebreab

Ermias Kebreab is an Eritrea-born animal scientist at the University of California, Davis, known for trials showing seaweed and 3-NOP feed additives cut cattle methane emissions.

Ermin

Ermin (juxtanodin, ERMN, KIAA1189) is an oligodendrocyte-specific actin-binding cytoskeletal protein of CNS myelin, localized to the outer cytoplasmic lip and paranodal loops; its loss compromises myelin integrity.

Erminio Costa

Erminio Costa (1924–2009) was an Italian-born American neuropharmacologist who showed that benzodiazepines act on the GABAA receptor, identified neurosteroids, and reported reelin down-regulation in schizophrenia.

ERN1

ERN1 (IRE1, IRE1α) is a human gene at 17q23.3 encoding a transmembrane serine/threonine kinase-endoribonuclease that senses ER unfolded proteins, splices XBP1 mRNA, and performs RIDD in the unfolded protein response.

Ernest Amory Codman

Ernest Amory Codman (1869–1940) was a Boston surgeon who pioneered tracking patient outcomes, proposing that hospitals follow every patient and ask "if not, why not?"

Ernest B. Hook

Ernest B. Hook is an American medical geneticist and professor emeritus at the University of California, Berkeley, known for proposing terathanasia and studying fetal deaths among chromosomally abnormal fetuses.

Ernest Basil Verney

Ernest Basil Verney (1894–1967) was a British physiologist and pharmacologist who demonstrated continuous secretion of antidiuretic hormone and introduced the osmoreceptor concept in his 1947 Croonian Lecture.

Ernest Beutler

Ernest Beutler (1928–2008) was a German-born American hematologist and physician-scientist who chaired medicine at City of Hope and led research at Scripps, transforming treatment of Gaucher disease and G6PD deficiency.

Ernest Craige

Ernest Craige (1918–2008) was an American cardiologist and first chief of the Division of Cardiology at UNC Chapel Hill, known for New England Journal of Medicine studies on heart sounds and echocardiography.

Ernest D. Laue

Ernest D. Laue, also known as Ernest Laue, is a structural biologist and Emeritus Professor at Cambridge, known for NuRD chromatin studies and 3D genome structures from single cells.

Ernest Dupré

Ernest Dupré (1862–1921) was a French psychiatrist and forensic physician who coined mythomanie and puérilisme mental, ending his career in the chair of mental diseases at Sainte-Anne.

Ernest Edward Tyzzer

Ernest Edward Tyzzer (1875–1965) was an American physician and pathologist at Harvard Medical School, known for discovering Tyzzer's disease, foundational work on bird parasites, and early tumor-immunity research.

Ernest Fourneau

Ernest Fourneau (1872–1949) was a French pharmacist and chemist who founded therapeutic chemistry in France, designing the anesthetic Stovaïne and directing drug research at the Institut Pasteur.

Ernest Fraenkel

Ernest Fraenkel is a computational systems biologist and Grover M. Hermann Professor at MIT who studies how molecular networks go wrong in diseases including ALS and cancer.

Ernest G. Peralta

Ernest G. Peralta (1959–1999) was an American molecular biologist and Harvard professor who cloned muscarinic receptors and showed how G proteins regulate potassium channels; he died of brain cancer at 40.

Ernest Gale

Ernest Frederick Gale (1914–2005) was a British microbiologist at Cambridge who recast bacteria as chemical machines, directing the MRC Unit for Chemical Microbiology and entering the Royal Society in 1953.
