Thus, monopolistic competition is a form of perfect competition. Although no product sold under monopolistic competition has a perfect substitute, each product has many close, albeit imperfect, substitutes, which have a cumulative effect on own-price elasticity of demand. With infinitely elastic demand...
and more obvious. College graduates are selling shoes and driving taxis; college students interfere with each other’s experiments and write false letters of recommendation in the intense competition for admission to graduate school.

The numbers of some kinds of sharks have fallen by over 90 percent in the last 20 to 30 years. Environmental protection 9 around the world, such as WildAid and the WWF, are teaching the public about “finning”. They have even asked governments to develop laws to stop the sale of ...
misunderstanding and needles controversy which arise from a lack of knowledge of the assumptions on which a theory is based, but also because of the extreme importance for economics of good judgment in choosing between rival sets of assumptions. For instance, it is suggested that the use of the...
of the parental genomes. In eukaryotes, sex involves meiosis-mixis-cycles and is tied to reproduction. The prevalence of sexual reproduction in eukaryotes is striking because of the obvious high costs of sex [2]: first, recombination during meiosis breaks up beneficial gene combinations; associated...

Chromosomal instability (CIN) is a hallmark of cancer, caused by persistent errors in chromosome segregation during mitosis. Aggressive cancers like high-grade serous ovarian cancer (HGSOC) and triple-negative breast cancer (TNBC) have a high frequency of CIN and TP53 mutations. Here, we show th...
First-person view (FPV) drone racing is a televised sport in which professional competitors pilot high-speed aircraft through a 3D circuit. Each pilot sees the environment from the perspective of their drone by means of video streamed from an onboard cam

Here, we present cryo-EM structures of full-length human long isoform IR (IR-B) in both the inactive and IGF2-bound active states, and short isoform IR (IR-A) in the IGF2-bound active state. Under saturated IGF2 concentrations, both the IR-A and IR-B adopt predominantly asymmetric ...
