Hot Jupiters - Flipped or Otherwise

Hot Jupiters - Flipped or Otherwise

Posted Thu, 12 May 2011 17:12:00 GMT by Mike Campbell

A ''hot Jupiter'' is a planet larger than the Jupiter of our own solar system which occupies an orbit close into its own star - hence ''hot Jupiter''. The conundrum was why should these giants be travelling in the wrong direction?

In what is being touted as artificial photosynthesis, researchers at the Ecole Polytechnique Federale de Lausanne have devised a technique for coating a cuprous oxide semiconductor so that it can use energy from the sun to take hydrogen from water.

Chinese city of Shenzhen has success with zero-emission public transport. China is making great strides to reduce its position as the world's number one greenhouse gas emitter. It has the largest fleet of electric taxis in the world, operating in the southern city of Shenzhen, near Hong Kong. Fifty of these five-seat taxis have been taking passengers since April 29th 2010 and have clocked up over 1,730,000 all-electric miles.

Scientists in America have unveiled information that suggests oceans can take vast amounts of time to recover from disasters such as mass extinctions. Researchers from the University of Chicago, West Virginia University and The Ohio State University examined fossil records dating from a mass extinction that devastated ocean life 360 million years ago, known as the Hangenberg event.

Ancient hominid goes from from nut-cracker to grass-grazer

A remote ancestor of humans, which had long been thought to have jaws and teeth specially adapted for nuts, has now been found to be more of a grass-mower than a nut-chomper. That's the conclusion of carbon isotope analysis of teeth enamel of Paranthropus boisei, published today in Proceedings of the National Academy of Sciences.

Solar Impulse, an aircraft powered only by solar power, prepares for its inaugural international flight. Previously, the single seated prototype, which has the wingspan of a Boeing 777, made history when it became the first solar powered plane of its type to fly 24 hours on solar power alone. Some 11,600 solar cells, situated on the wings, charge lithium batteries, which, in turn, power the engines.

Acoustic surveying is bringing the amazing deep-sea hunts of beaked whales to light, in research published today in PloS One, the open-access science journal. Not only does the study provide a better understanding of an enigmatic group of marine mammals - the information could help avoid the tragedy of sonar-associated whale strandings.

Mapping Subtle Changes in Gravity

Mapping Subtle Changes in Gravity

Posted Mon, 25 Apr 2011 21:30:01 GMT by Mike Campbell

Any schoolchild should know that gravity is the force that keeps us on the ground and that the force of gravity is 9.8 ms-2. However, the force of gravity is not exactly the same at all points on the planet. This is because the density of the earth is not uniform; the earth is not a perfect sphere and therefore the height of the surface above the core varies from ocean deeps to high mountains. The gravitational pull of the earth is inversely proportional to the height one is above it - if you are far enough from the surface you experience weightlessness, after all.

Mars may well have had a much denser CO2-rich atmosphere hundreds of thousands of years ago - one with wilder dust storms and that was more likely to support running water. That's the claim coming from a new analysis of satellite radar data over the Martian southern ice cap - published in Science today - which hints at a thick wedge of frozen CO2 there that contains 30 times the 'dry ice' of previous estimates.

An incredibly detailed three dimensional map of the 'green architecture' of the US, including forest canopy heights and vegetation levels down to each hectare, has been released today by the Woods Hole Research Center. The fruit of five years labor, which is freely downloadable, paints a detailed snapshot of the carbon stocks above the soil, one that will aid forest managers, ecologists and climate scientists for years to come.

An animal rights activist in China stopped a truckload of dogs from being transported to Beijing restaurants, then microblogged for help to successfully prevent the delivery of the dogs. Online news report different numbers for the dog count, but there were more than 400 of them cramped togther in cages stacked in the truck.

The bacterial ecosystems in Britain's soil have been mapped in a worldwide first. The soil microbe map gives us a unique baseline to measure environmental change. The research took four years to complete between 2007 and 2011. Far from being randomly distributed in soil these bacterial communities or biomes are organised according to their associated plant communities above

Fuel Cell vehicles will be on London streets for Olympic Games and carrying passengers afterwards. A consortium of innovative companies have created a pair of prototype zero emission fuel cell London taxis - the famous ''Black Cabs'' that carry passengers around London. Though looking exactly like the familiar taxis - they are conversions, underneath the hood they have an electric motor powered by a hydrogen fuel cell and batteries

A scientist based at an American university has deposited a series of desert plant seeds in a collection designed to protect species should they die out due to environmental events. The University of Arizona (UA) has confirmed that Margaret Norem, a researcher from its Department of Arboretum Affairs, took the seeds to the Svalbard Global Seed Vault on a remote island off the coast of Norway, a few hundred miles from the North Pole.

Is brighter better? It is for ducks! How do you know how to pick a mate? Best body? Big car? Lots of money? Female mallards have their own unique way of determining which mate they should choose. Females of all species want to pick the best father for their offspring. This is the male with the best genes, who will produce successful, healthy children.

What if you could change the color and tint of your windows and re-circulate the solar energy as electricity? Utilizing natural light by installing more windows allows you to rely less on artificial light sources; however the extra window space can negatively influence interior climate control and stress HVAC systems. A new technology in the glass manufacturing industry allows windows to collect solar energy and be reused. The color and tint of the windows can be controlled as well.
