To całkiem ciekawa tak przy tuva jagell zamieszkajmy razem swoim crop milk. Both male and female pigeons create the milk the crop, a section of the esophagus designed to store food temporarily. As is the case with mammal milk, the creation of crop milk is regulated by the hormone prolactin. Newly-hatched pigeons drink crop milk until they're weaned off it after four weeks or 15. ONE STUDY SUGGESTS THAT, GIVEN THE RIGHT CONDITIONS, THEY'RE AS GOOD IDENTIFYING CANCER AS DOCTORS. We've already established that pigeons are excellent at differentiating between artists and words, but a 2015 study revealed they can also distinguish between malignant and benign growths the right conditions. Researchers at University of California Medical Center put 16 pigeons a room with magnified biopsies of potential breast cancers. If the pigeons correctly identified them as either benign or malignant, they got a treat, According to Once trained, the pigeons' average diagnostic accuracy reached impressive 85 percent. But when a flock sourcing approach was taken, which the most common answer among all subjects was used, group accuracy climbed to a staggering 99 percent, or what would be expected from a pathologist. The pigeons were also able to apply their knowledge to novel images, showing the findings weren't simply a result of rote memorization. Mammograms proved to be more of a challenge, however; the birds could memorize signs of cancer the images they were trained on but could not identify the signs new images. No matter how impressive their results, I 't anticipate that pigeons, no matter how good they become at pathology or radiology, be playing a role actual patient care-certainly for the foreseeable future, study co-author Richard M. Levenson told There are just too regulatory barriers-at least the West. Obama today faced a fresh wave of attacks over her lavish break Spain with 40 friends, which could easily cost U.S. taxpayers a staggering £50 a day. The First has been lambasted for her extravagance at a time when the economy is still struggling. One blogger went far as to brand her a modern-day And her critics be further annoyed when they learn that the president's wife had a Spanish beach closed off today that she, her daughter and their entourage could go for a swim. Spanish police cleared off a stretch of beach at the Villa Padierna Hotel Marbella after the Obamas had finished a busy day of sightseeing. Police used palm trees and police tape to off the boundaries of a 100-yard expanse for the American delegation. On either side, onlookers gawked and police occasionally stopped and searched lovers if they strayed too close to the private party. It is unclear whether the police presence was paid for by Spain or whether a nasty invoice could be landing the lap of the American taxpayer. The exact cost of the trip is unclear as Mrs Obama, 46, and her friends are footing personal expenses themselves which is just as well. For a start, they be paying for the 60 rooms booked at the 129-room Hotel Villa Padierna. With basic rooms starting around £380 each, the nightly be no less than £22. Meals also be picked up by the Obamas and friends. Spanish newspaper El Mundo detailed the Obamas' dinner on their first night Spain. The tapas menu for the delegation included sea bass tartare, strawberry gazpacho and sardines, followed by a main course of lobster with seaweed risotto. The meal cost about £40 a head, according to El Mundo which means a topping £1 would have hit the table if all 40 friends dined together. Stretched over five nights that's £8 for dinner alone. Whether or not the taxpaying American be paying for meals, they definitely be footing the for the First 's 68-strong security detail, her personal staff and the use of presidential jet Air Force Two. The per diems for the secret service team runs at around £172 each, which amounts to nearly £60 for the length of the break. Use of Air Force Two, the Air Force version of a 757, comes at £91 for the round trip. This does not include time on the Mrs Obama's personal staff, of which there are unknown amount and who might cost considerably more per day, also have to be taken into account. The American public also cover the cost of the only official part of the holiday, a visit to the Spanish royal family on the island of Majorca.
