An international team of scientists working in Italy have foun stanley kubek d the oldest samples of arthropods preserved in amber 鈥?a finding that is 100 million years older than previous fossilized samples. The insects, a fly and two mites, are the first ever to be discovered from the Triassic era. The group findings will help biologists gain a better evolutionary understanding of these organisms and the stanley thermos time periods within which they developed. Amber droplets can be a goldmine for paleontologists. Even a millimeter sized droplet can contain extremely well preserved specimens of organisms that lived eons ago 鈥?specimens that can be observed with microscopic fidelity. Globules of fossilized resin can range in age from the Carboniferous era about 340 million years ago to about 40,000 years ago, and were produced by plants like tree ferns, flowering trees, and conifers. The amber droplets, which are only 2-6 millimeters long, were discovered buried in the Dolomite Alps of northeastern Italy. Paleontologists working there were able to uncover about 70,000 droplets 鈥?all of which were screened for signs of preserved life. Paleontologists suspect that arthropods, a class of organism tha stanley us t includes insects, arachnids, and crustaceans, have been around for at least 400 million years. Two of the arthropods are a new species of mites 鈥?members of an extremely specialized group that fed on plants and sometimes formed an abnormal growth called galls.

Testing new and potential life-saving drugs can be a harrowing process because of the risk involved with not knowing how a substance will react once in the human body. Harvards scientists are hoping that microchips, such as the one pictured above, can mimic the fu stanley nz nction of human organs well enough for them to botella stanley test those drugs. While the chip doesn ;t look like a human organ in any way, Inhabitat says that the little, seemingly simple objects are more than capable of replicating the processes of those organs. Each faux organ is made from a clear flexible polymer and stanley cup is about the size of an average computer memory stick. The microchip organs feature hollow microfluidic channels that are lined with living human cells. Although they don ;t resemble the real shape of these organs inside the body, the cells allow scientists to observe how these organs might react to new drugs. The Harvard researchers hope to make 10 of these chips each one associated with a different organ and has FDA Chief Scientist Jesse Goodman so excited that he believes it could be the best way to test new drugs. Along with $37 million in funding from DARPA, that a strong endorsement. [Harvard via Inhabitat] MedicineMicrochipsScience
