Traumatic Insemination

Traumatic insemination is a form of mating in some invertebrates in which the male pierces the female's abdomen and injects sperm through the wound. The sperm then travel to the female's ovaries. Though it often results in successful reproduction, the practice can be harmful to females, as the wound is susceptible to infection, and immune reactions can occur. Homosexual and inter-species instances of the practice have also been observed. What insect reproduces solely by traumatic insemination? More...

Montreal Protocol Signed to Protect the Ozone Layer (1987)

The Montreal Protocol was enacted in response to the discovery that the ozone layer—which shields life on Earth from harmful radiation—was diminishing. Signed by the majority of the world's nations, the treaty mandates the decreased use of ozone-depleting substances such as chlorofluorocarbons (CFCs) and has been amended several times based on new scientific data. By 1993, CFC production had dropped dramatically. If the agreement is followed, the ozone layer is expected to recover by what year? More...

Mexico Festival of Independence (2017)

At 11 o'clock on the night of September 15 in Mexico City, the president appears on the balcony of the National Palace and proclaims the famous Grito de Dolores ("cry of Dolores")—the "call to freedom" that the priest Miguel Hidalgo y Costilla used to rouse the peasant population to fight for their independence in 1810. The people respond by cheering Viva México! and shooting off fireworks. The following day is Independence Day, which is celebrated with fireworks, the ringing of cathedral bells, and a huge military parade. More...

Gerbils Regain Hearing through Stem Cell Treatment

UK researchers have restored hearing in animals with the use of stem cells for the first time. About 10 percent of people with profound hearing loss have damaged nerve cells, called spiral ganglion neurons, that fail to detect signals created by sound vibrations. Using stem cells from a human embryo—which can become any other type of cell—the scientists created cells similar to the spiral ganglion neurons. They then injected them into the ears of deaf gerbils. By the end of the study, an average of 45 percent of the animals' hearing range had been restored. However, scientists said the possibility of treating humans in this way is still distant. More...
