The long-held idea that only vertebrates have sophisticated adaptive immune systems that can protect them for life against many pathogens after being infected by them just once has been revised in recent years.

It turns out that many insects also have a form of immune memory that protects them against reinvasion by a pathogen they have previously encountered. This was just one of the striking discoveries discussed at the recent conference on Innate Immunity and the Environment, organized by the European Science Foundation (ESF).

To ensure you have a green Christmas this season, Bluewater, the UKs leading shopping center, have devised an eco-friendly scientific formula on how to wrap a Christmas present after estimating British consumers will waste over one ton of wrapping paper this Christmas (see note 1 at the bottom).

Bluewater discovered that Brits continually overestimate the amount of paper they need to wrap their Christmas presents.

Life on Earth may have originated as the organic filling in a multilayer sandwich of mica sheets, according to Helen Hansma of the National Science Foundation and the University of California, Santa Barbara.

In a presentation at the American Society for Cell Biology’s 47th annual meeting, she proposes that the narrow, confined spaces between nonliving mica layers could have provided exactly the right conditions for the rise of the first biomolecules.

The “mica hypothesis” provides possible answers to many questions about life’s origins, according to Hansma. This layered mineral could have provided support, shelter, and an energy source for the development of precellular life, while leaving artifacts in the structure of living things today, including the periodicity of RNA.

The data are in. Divorce is bad for the environment.

A novel study that links divorce with the environment shows a global trend of soaring divorce rates has created more households with fewer people, has taken up more space and has gobbled up more energy and water. The findings of Jianguo “Jack” Liu and Eunice Yu at Michigan State University are published in this week’s online edition of the Proceedings of the National Academy of Sciences.

A statistical remedy: Fall back in love. Cohabitation means less urban sprawl and softens the environmental hit.

The price of oil nearly reached $100 a barrel recently, but a new University of Delaware prototype vehicle demonstrates how the cost of the black stuff could become a concern of the past.

A team of UD faculty has created a system that enables vehicles to not only run on electricity alone, but also to generate revenue by storing and providing electricity for utilities. The technology--known as V2G, for vehicle-to-grid--lets electricity flow from the car’s battery to power lines and back.

“When I get home, I’ll charge up and then switch into V2G mode,” said Willett Kempton, UD associate professor of marine policy and a V2G pioneer who began developing the technology more than a decade ago and who is now testing the new prototype vehicle.
