Huge amber deposit discovered in India

Those who are proud to have a piece of amber that holds a little animal trapped in it maybe should not continue to read this. For what can be seen in the millions of years-old tree resin is almost always just a paper-thin façade. If sliced down the middle, you would find no more than a hollow space covered in some sort of "insect photo wallpaper." This does not apply to the amber Bonn paleontologist Professor Dr. Jes Rust and his colleagues have been looking at for two years. The lumps that resemble herbal cough drops are "full of it," containing numerous insect bodies, ...

New trove of fossils suggests global distribution of tropical forest ecosystems in the Eocene

Bees, termites, spiders, and flies entombed in a newly-excavated amber deposit are challenging the assumption that India was an isolated island-continent in the Early Eocene, or 52-50 million years ago. Arthropods found in the Cambay deposit from western India are not unique—as would be expected on an island—but rather have close evolutionary relationships with fossils from other continents. The amber is also the oldest evidence of a tropical broadleaf rainforest in Asia. The discovery is published this week in Proceedings of the National Academy of Sciences. "We know ...

Allergies and wheezing illnesses in childhood may be determined in the womb

A child's chances of developing allergies or wheezing is related to how he or she grew at vital stages in the womb, according to scientists from the University of Southampton. The new research, funded by the Medical Research Council (MRC) and the British Lung Foundation, and undertaken at Southampton General Hospital, reveals that fetuses which develop quickly in early pregnancy but falter later in pregnancy are likely to go on to develop allergies and asthma as children. Scientists believe this is due to changes in the development of their immune system and lungs. A ...

Daily vibration may help aging bones stay healthy

AUGUSTA, Ga. - A daily dose of whole body vibration may help reduce the usual bone density loss that occurs with age, Medical College of Georgia researchers report. Twelve weeks of daily, 30-minute sessions in 18-month old male mice – which equate to 55- to 65-year-old humans – appear to forestall the expected annual loss that can result in fractures, disability and death. Dr. Karl H. Wenger, biomedical engineer in the MCG Schools of Graduate Studies and Medicine, reported the findings with his colleagues in the journal Bone. Researchers found vibration improved density ...

Plant stem cells could be fruitful source of low-cost cancer drug

A popular cancer drug could be produced cheaply and sustainably using stem cells derived from trees, a study suggests. Researchers have isolated and grown stem cells from a yew tree whose bark is a natural source of the anticancer compound paclitaxel. The development could enable the compound to be produced on a commercial scale at low cost, with no harmful by-products. Scientists and engineers behind the development say the drug treatment – currently used on lung, ovarian, breast, head and neck cancer – could become cheaper and more widely available. The study was ...
