Do mosquitos actually bite some people more than others? - Maria Elena D...
Explore the science of what attracts mosquitos, and find out why mosquitos bite some people more than others.
--
Some swear they’re cursed to be hunted by mosquitos while their close-by companions are regularly left unscathed. Are mosquitos really attracted to some people more than others? And if so, is there anything we can do about it? Maria Elena De Obaldia digs into what factors make people tasty targets for these pesky insects.
Lesson by Maria Elena De Obaldia, directed by Anton Bogaty.

Pantry Pests
Insect pests including the Mediterranean flour moth, the Indian mealmoth, the cigarette beetle, the drugstore beetle, the confused flour beetle, the red flour beetle, the merchant grain beetle, the sawtoothed grain beetle, the wheat weevil, the maize weevil and the rice weevil infest stored dry foods such as flour, cereals and pasta.
In the home, foodstuffs found to be infested are usually discarded, and storing such products in sealed containers should prevent the problem from reoccurring. The eggs of these insects are likely to go unnoticed, with the larvae being the destructive life stage, and the adult the most noticeable stage. Since pesticides are not safe to use near food, alternative treatments such as freezing for four days at 0 °F (−18 °C) or baking for half an hour at 130 °F (54 °C) should kill any insects present.

Urban & Natural Rodent Control
Urban rodent control
Rodent control is vital in cities. New York City and cities across the state dramatically reduced their rodent populations in the early 1970s. Rio de Janeiro claims a reduction of 80% over only 2 years shortly thereafter. To better target efforts, London began scientifically surveying populations in 1972 and this was so useful that all Local Authorities in England and Wales soon followed.
Natural rodent control
Several wildlife rehabilitation organizations encourage natural form of rodent control through exclusion and predator support and preventing secondary poisoning altogether. The United States Environmental Protection Agency notes in its Proposed Risk Mitigation Decision for Nine Rodenticides that "without habitat modification to make areas less attractive to commensal rodents, even eradication will not prevent new populations from recolonizing the habitat." The United States Environmental Protection Agency has prescribed guidelines for natural rodent control and for safe trapping in residential areas with subsequent release to the wild. People sometimes attempt to limit rodent damage using repellents. Balsam fir oil from the tree Abies balsamea is an EPA approved non-toxic rodent repellent. Acacia polyacantha subsp. campylacantha root emits chemical compounds that repel animals including rats.

How smart are dolphins? - Lori Marino
Dolphins are one of the smartest animal species on Earth. In fact, their encephalization quotient (their brain size compared to the average for their body size) is second only to humans. But exactly how smart are they? Lori Marino details some incredible facts about dolphins.

Insulation
Boron, a known pesticide can be impregnated into the paper fibers of cellulose insulation at certain levels to achieve a mechanical kill factor for self-grooming insects such as ants, cockroaches, termites, and more. The addition of insulation into the attic and walls of a structure can provide control of common pests in addition to known insulation benefits such a robust thermal envelope and acoustic noise-canceling properties. The EPA regulates this type of general-use pesticide within the United States allowing it to only be sold and installed by licensed pest management professionals as part of an integrated pest management program. Simply adding Boron or an EPA-registered pesticide to an insulation does not qualify it as a pesticide. The dosage and method must be carefully controlled and monitored.

Sterilization
Populations of pest insects can sometimes be dramatically reduced by the release of sterile individuals. This involves the mass rearing of a pest, sterilizing it by means of X-rays or some other means, and releasing it into a wild population. It is particularly useful where a female only mates once and where the insect does not disperse widely. This technique has been successfully used against the New World screw-worm fly, some species of tsetse fly, tropical fruit flies, the pink bollworm and the codling moth, among others.
Laboratory studies conducted with U-5897 (3-chloro-1,2-propanediol) were attempted in the early 1970s for rat control, although these proved unsuccessful. In 2013, New York City tested sterilization traps, demonstrating a 43% reduction in rat populations. The product ContraPest was approved for the sterilization of rodents by the United States Environmental Protection Agency in August 2016.

Jellyfish predate dinosaurs. How have they survived so long? - David Gruber
Some are longer than a blue whale. Others are barely larger than a grain of sand. One species unleashes one of the most deadly venoms on earth; another holds a secret that’s behind some of the greatest breakthroughs in biology. They’ve inhabited the ocean for at least half a billion years, and they’re still flourishing. David Gruber investigates the secret powers of jellyfish.

Fumigation
Fumigation is the treatment of a structure to kill pests such as wood-boring beetles by sealing it or surrounding it with an airtight cover such as a tent, and fogging with liquid insecticide for an extended period, typically of 24–72 hours. This is costly and inconvenient as the structure cannot be used during the treatment, but it targets all life stages of pests.
An alternative, space treatment, is fogging or misting to disperse a liquid insecticide in the atmosphere within a building without evacuation or airtight sealing, allowing most work within the building to continue, at the cost of reduced penetration. Contact insecticides are generally used to minimize long-lasting residual effects.

Why the octopus brain is so extraordinary - Cláudio L. Guerra
Octopuses have the ability to solve puzzles, learn through observation, and even use tools – just like humans. But what makes octopus intelligence so amazing is that it comes from a biological structure completely different from ours. Cláudio L. Guerra takes a look inside the amazing octopus brain.

Poisoned Bait
Poisoned bait is a common method for controlling rats, mice, birds, slugs, snails, ants, cockroaches, and other pests. The basic granules, or other formulation, contains a food attractant for the target species and a suitable poison. For ants, a slow-acting toxin is needed so that the workers have time to carry the substance back to the colony, and for flies, a quick-acting substance to prevent further egg-laying and nuisance. Baits for slugs and snails often contain the molluscide metaldehyde, dangerous to children and household pets.
An article in Scientific American in 1885 described effective elimination of a cockroach infestation using fresh cucumber peels.
