For 50 years, Live Science says, cryptic teeth in Alberta separated from the bodies have been interpreted as bird teeth. That’s a load of croc, Laura Geggel writes. They’re really crocodile teeth. Sydney Mohr says, “No one has ever taken a really good look at them.” She compared them to teeth of extinct bird groups and crocodilians, and found that they matched juvenile croc teeth the best.It’s also possible that some of the teeth did, in fact, come from birds, Mohr said. But even if they didn’t, that doesn’t mean prehistoric birds didn’t fly over southern Alberta. It’s possible that toothless birds lived there, or that toothed-bird remains simply weren’t preserved, she said.Speaking of toothless birds, PNAS built an evolutionary tale out of tooth loss. That’s right; loss of teeth in birds who evolved beaks. They say that their hypothesis “provides insight into the macroevolution of avian beaks.”Shifts toward earlier cessation of postnatal tooth development can be identified in fish, amphibians, and mammals that are edentulous [toothless] as adults; therefore the identification of similar transitions in multiple Mesozoic theropod dinosaur lineages strongly implies that heterochronic truncation of odontogenesis played an important role in the macroevolution of beaks in modern birds.Turning tooth development off in the embryo seems an easy thing for chance to do. Wouldn’t a better case of macroevolution be to evolve teeth from scratch?The dinosaur-eating frog: Sounds like a horror movie for the Jurassic Park series: “Giant Frog Eats T. rex”. Actually, this frog, with a powerful bite, probably concentrated on smaller dinos. They didn’t find dinosaurs in its stomach, but Science Daily reports,South American horned frog: credit, Kristopher LappinScientists say that a large, now extinct, frog called Beelzebufo that lived about 68 million years ago in Madagascar would have been capable of eating small dinosaurs….The study found that small horned frogs, with head width of about 4.5cm, can bite with a force of 30 newtons (N) or about 3 kg or 6.6 lbs. A scaling experiment, comparing bite force with head and body size, calculated that large horned frogs that are found in the tropical and subtropical moist lowland forests of South America, with a head width of up to 10 cm, would have a bite force of almost 500 N. This is comparable to reptiles and mammals with a similar head size.“This would feel like having 50 litres of water balanced on your fingertip,” says Professor Kristopher Lappin, Professor of Biological Sciences at California State Polytechnic University — Pomona.Based on their scaling relationship, the scientists estimated the bite force of the giant extinct frog Beelzebufo — which is in many ways similar to living horned frogs — may have had a bite up to 2200 N, comparable to formidable mammalian predators such as wolves and female tigers.“At this bite force, Beelzebufo would have been capable of subduing the small and juvenile dinosaurs that shared its environment,” says Dr Jones.Doesn’t this imply that extinct frogs were more fit than modern frogs? The scientists didn’t go into that.Imagining ancestors. Fossils of small, agile predators: how could these be the ancestors of giant sauropods, the largest herbivores that ever walked the earth? Science Daily reports without criticism a remarkable thesis by evolutionists in Munich who connect these two unlikely relatives:The best known sauropod dinosaurs were huge herbivorous creatures, whose brain structures were markedly different from those of their evolutionary predecessors, for the earliest representatives of the group were small, lithe carnivores….However, the early representatives of the lineage that led to these lumbering giants were strikingly different in form and habits. For a start, they were carnivores — like Saturnalia tupiniquim, an early sauropod dinosaur that was about the same size as a modern wolf.This hypothesis, based entirely on comparing dentition, reminds Darwin skeptics of the evolutionary story about a wolf-sized land animal becoming a gigantic whale. And what about the neck becoming longer? Remember what evolutionists admitted about the classic evolutionary story of the giraffe? (9/16/17). This story is even more implausible.The upside-down ankylosaurs. Paleontologists from Alberta were curious why 70% of ankylosaurs are found belly up. Is that due to chance, or to some other reason? Did predators turn them over? Apparently not; most lack tooth marks. Live Science says ” the researchers tested what turned out to be the correct hypothesis — that the ankylosaurs had either drowned or been swept out to sea once they died.” The “bloat and float” hypothesis pictures them filling with gas after drowning and flipping over. Glyptodonts, which evolutionists date earlier, are also often found on their backs. But since armored dinosaurs are large and heavy, up to 26 feet long and weighing 8 tons, doesn’t that require rapid burial? Laura Geggel calmly asserts, “These Late Cretaceous armored beasts were swept out to sea after they died, where they flipped over, sunk down to the seabed and fossilized, the researchers found.” But if that hypothesis were correct, we should expect to observe that happening to large, heavy animals today. Typically, animals are quickly eaten at sea. What could sweep a huge, heavy animal like an ankylosaur out to sea? Doesn’t that require a rather large Flood?Fossils do not interpret themselves. They are seen through the lens of a worldview. Evolutionists don’t just see fossils through Darwin-colored glasses. That would imply they could take the glasses off and think objectively. No; their Darwin worldview has been carved into their eyeballs like irreversible lasik surgery. Darwin Lasik distorts every bone it sees, like seeing fossils through a fun-house mirror that stre-e-e-t-t-t-ches things into millions of years.

Amid speculation that the Bharatiya Janata Party-led State government was considering halting ‘excess’ water supply for agriculture to the Baramati and Indapur talukas, Nationalist Congress Party (NCP) chief Sharad Pawar on Wednesday said any comment on the drought and water crisis must be made with extreme sensitivity.“The whole of Maharashtra is in the grip of an unprecedented water crisis. At such a time, there is a need to speak with extreme sensitivity on this issue. One must ensure there is no discrimination between different regions and talukas in the State as regards the distribution of water,” Mr. Pawar said, urging the government not to resort to politics over drought and water allocation.The NCP chief, who was on a tour of the drought-hit parts of Baramati, was responding to the rumours that State Water Resources Minister Girish Mahajan was thinking of cutting the allegedly excess water supply from the Nira left bank canal to Indapur and Baramati.Mr. Mahajan has said that Baramati and Indapur — strongholds of the Pawar clan and Congress leader Harshavardhan Patil respectively — have been receiving more water than required. He implied that Mr. Pawar and his nephew, senior NCP leader Ajit Pawar, had tweaked rules to divert more water to Baramati when the Congress-NCP government was in power.The Nira project consists of a storage reservoir on the Yelwandi river near Bhatgar and two canals. The left bank canal, which originates from the Nira river at Vir, irrigates areas of Pune district, including Baramati and Indapur, and parts of Solapur district. The right bank canal irrigates some other tehsils in Solapur.Mr. Mahajan said more water was diverted to the left canal that passed through Baramati and Indapur, while areas in Solapur district like Malshiras, Madha and Sangola were left high and dry.“The local MP from Madha and other leaders from Solapur district have complained that five talukas are receiving only 40% water from the Nira left bank canal, while Baramati and Indapur are receiving the remaining 60%,” Mr. Mahajan told a vernacular television channel. It is believed that the newly elected Madha MP Ranjitsinh Naik-Nimbalkar and other leaders from Solapur like Ranjitsinh Mohite-Patil, son of former NCP MP Vijaysinh Mohite-Patil, met the minister on this matter. According to rumours, Mr. Mahajan is expected to issue an ordinance on this matter soon. The move, if implemented, is seen as a stratagem on part of the BJP to break the Pawars’ stranglehold on Baramati ahead of the Assembly elections.Ajit Pawar, who toured Baramati with his uncle, said, “I have yet to hear anything said by Mr. Mahajan on this issue. I am not aware if such a decision has been mooted… But the government should know that there are people living on both sides of the Nira canal.” Senior Congress leader Harshavardhan Patil, whose bastion is Indapur, however warned of a strong agitation if such an ordinance comes into effect. “The Water Resource Department has no right to take such a decision, if at all it is being mulled. Indapur and Baramati are catchment areas. If water supply to these talukas is going to be stopped, we will be compelled to launch an agitation and take legal recourse,” Mr. Patil said.

The rock python is “vicious”, according to Kenneth Krysko of the Florida Museum of Natural History. It is even meaner than the Burmese pythons, which have been known to eat alligators, and which have already taken up residence in the nearby Everglades National Park, where they have wiped out thousands of native animals. Another major alien in the park is the boa constrictor.Six specimens of Africa’s longest snake have been discovered in a single square mile west of Miami, Florida, since the first was sighted in 2002. Krysko believes the original snakes may have been released by pet breeders when they grew too big, or when the breeders were surprised by their aggressiveness. The finding of two hatchlings and a pregnant female suggests the snakes are settling in.The rock python, like the Burmese python and boa constrictor, is not poisonous but kills its prey by constricting it and suffocating it to death before swallowing it.With the Everglades National Park just across the road, the rock python may already have joined the other giant aliens in the park in wiping out the native fauna. According to Robert Reed of the U.S. Geological Survey in Colorado, the new snake might eat any warm-blooded animal it can ingest. The Burmese python is known to eat dozens of species, including white-tailed deer and even six-foot alligators, and Reed expects the rock python to do the same.Another potential problem is inter-breeding of the African rock python and the Burmese python to produce a hybrid species. This has been known to happen in captivity, and while most such offspring are infertile, there is a possibility that offspring of the two species could be even hardier and more deadly than their parents, according to Reed.Kristina Serbesoff-King of the Nature Conservancy in Florida said that we should learn from past mistakes and try to eliminate the rock python while it is still confined to a relatively small area. One approach could be a python patrol, similar to the one the Nature Conservancy ran to try to reduce the numbers of Burmese pythons.If the African rock python is not stopped in its tracks, the scientists agree the problem may be even worse than the Burmese python problem because the rock python is far more aggressive. In its native home the African rock python is known to attack humans, according to Krysko, and if hidden in a swamp, it could strike before you even knew it was there. It could pose a particular danger for pets and small children.© 2009 PhysOrg.com (PhysOrg.com) — New studies suggest a 20 foot snake, the African rock python, is making its home in Florida and could soon invade the Everglades National Park.

Play Movie of nanoparticles moving through mucus. Credit: Schneider et al. Sci. Adv. 2017;3:e1601556 The nanoparticles, the team notes, were created using biodegradable materials that prior research found safe for internal use. Testing in mice, they report, showed the particle carriers stayed in the lungs for several hours—they also proved to be more effective than conventional therapies at reducing asthma symptoms such as irritation. The researchers suggest that MPPs could offer a better treatment plan for lung patients by providing a therapy that maintains drug levels in the lungs for longer periods of time, reducing the need for repeated dosing, which itself can cause lung irritation.

Schneider et al. Nanoparticles that do not adhere to mucus provide uniform and long-lasting drug delivery to airways following inhalation, Science Advances (2017). DOI: 10.1126/sciadv.1601556AbstractMucoadhesive particles (MAP) have been widely explored for pulmonary drug delivery because of their perceived benefits in improving particle residence in the lungs. However, retention of particles adhesively trapped in airway mucus may be limited by physiologic mucus clearance mechanisms. In contrast, particles that avoid mucoadhesion and have diameters smaller than mucus mesh spacings rapidly penetrate mucus layers [mucus-penetrating particles (MPP)], which we hypothesized would provide prolonged lung retention compared to MAP. We compared in vivo behaviors of variously sized, polystyrene-based MAP and MPP in the lungs following inhalation. MAP, regardless of particle size, were aggregated and poorly distributed throughout the airways, leading to rapid clearance from the lungs. Conversely, MPP as large as 300 nm exhibited uniform distribution and markedly enhanced retention compared to size-matched MAP. On the basis of these findings, we formulated biodegradable MPP (b-MPP) with an average diameter of <300 nm and examined their behavior following inhalation relative to similarly sized biodegradable MAP (b-MAP). Although b-MPP diffused rapidly through human airway mucus ex vivo, b-MAP did not. Rapid b-MPP movements in mucus ex vivo correlated to a more uniform distribution within the airways and enhanced lung retention time as compared to b-MAP. Furthermore, inhalation of b-MPP loaded with dexamethasone sodium phosphate (DP) significantly reduced inflammation in a mouse model of acute lung inflammation compared to both carrier-free DP and DP-loaded MAP. These studies provide a careful head-to-head comparison of MAP versus MPP following inhalation and challenge a long-standing dogma that favored the use of MAP for pulmonary drug delivery.

Such conditions include asthma, in which bronchi spasm, making it difficult to breathe; cystic fibrosis, in which over-production of mucus leads to blocking of bronchi; and COPD, in which obstructions form in bronchial passages. Fortunately, these types of ailments are all treatable to some degree, though they cannot be cured. For that reason, scientists continue to look for ways to improve current therapies.Currently, lung ailments such as cystic fibrosis, COPD and asthma are treated with inhaled drugs such as corticosteroids that adhere to the walls of air passages. In some instances, they are carried by what are known as mucoadhesive particles, (MAPs), but, as the researchers note, thick mucus often builds up on such passageways, lessening the effectiveness of the delivery system. In this new effort, the researchers took a different approach—rather than trying to make medicines that adhere do their job better, they turned to nanoparticles that are small enough to make their way through mucus membranes to the lining of the lungs themselves, offering direct medication application to affected areas. Called mucus-penetrating particles (MPP), they remain in the lungs, releasing medication for an extended period of time.
