Cockroaches stop breathing to stay alive!September 23rd, 2009 MELBOURNE - Australian scientists have found that cockroaches hold their breath in order to stay alive. The study done by Dr Craig White, an animal physiologist at the University of Queensland, Brisbane and his team has been published in the Journal of Experimental Biology.
Study: Heart patients who get the flu are more likely to have a heart attackSeptember 21st, 2009 Study: Flu viruses can spark heart attacksLONDON — Heart patients who catch the flu may have more to worry about than just a fever or the sniffles: the virus could also spark a heart attack, new research shows. Amid the global outbreak of swine flu, experts say it's crucial that heart patients get vaccinated against both regular flu and swine flu to avoid medical problems.
Future of forests really bleak: StudySeptember 16th, 2009 WASHINGTON - The composition of some of our forests may be quite different 200 to 400 years hence, says a recent study. The study found that temperature and photosynthetic active radiation were the two most important variables in predicting what forest landscapes may look like in the future.
Scientists unveil biological process that spurs blood vessels growthSeptember 15th, 2009 WASHINGTON - In a novel study, scientists from University of North Carolina and the College of Arts and Sciences have identified a novel mechanism that triggers blood vessel growth. They have found that vascular networks form and expand by "sprouting" similar to the way trees grow new branches.
Ancient oceans yield clues to the origins of animal life on EarthSeptember 10th, 2009 WASHINGTON - Analysis of a rock type found only in the world's oldest oceans has shed new light on how large animals first got a foothold on the Earth. By analysing the isotopes of chromium in iron-rich sediments formed in the ancient oceans, a scientific team, led by Professor Robert Frei at the University of Copenhagen in Denmark, has found that a rise in atmospheric oxygen levels 580 million years ago was closely followed by the evolution of animal life.
2 viruses threaten Michigan blueberry industry; scientists forced to destroy research plantsAugust 31st, 2009 Blueberry virus strikes Michigan research centerDETROIT — Two destructive viruses have shown up in blueberry bushes in Michigan. Michigan is the nation's No.
Why our red blood turns blue after entering veinsAugust 29th, 2009 WASHINGTON - Ever imagined why our blood, which is actually red in colour turns blue in veins? Well, it's because of the oxygen. According to experts, heart pumps blood to the lungs to pick up oxygen.
Fusing of ancient microbes reveals new pathway for evolution of life on EarthAugust 20th, 2009 WASHINGTON - NASA-funded research has found that humans not might be walking on Earth today if not for the ancient fusing of two microscopic, single-celled organisms called prokaryotes 2.5 billion years ago, which reveals a new pathway for the evolution of life on Earth. By comparing proteins present in more than 3000 different prokaryotes - a type of single-celled organism without a nucleus - molecular biologist James A.
Defective mitochondria slow aging in miceJuly 23rd, 2009 WASHINGTON - Scientists from McGill University have revealed that defective mitochondria actually slow down aging in mice. Mice with a defective mitochondrial protein called MCLK1 produce elevated amounts of reactive oxygen when young, which could spell disaster, but the new study found that mice actually age at a slower rate and live longer than normal mice.
Massive greening of Earth 700 mln yrs ago triggered off explosive growth of lifeJuly 9th, 2009 WASHINGTON - A team of scientists has suggested a massive greening of the planet by non-vascular plants, or 'primitive ground huggers', triggered off the Cambrian explosion of life, roughly 700 million years ago. The Cambrian explosion of life was one of the biggest moments in Earth's lifetime, around 540 million years ago, when complex, multi-cellular life burst out all over the planet.
Planet's early greening fuelled explosive growth of lifeJuly 9th, 2009 WASHINGTON - Roughly 540 million years ago, something happened to fuel the explosive growth of complex, multi-cellular life, all over the planet, according to recent research. Researchers led by Arizona State University (ASU) geologist L.
Honeybees form 'bee balls' to mob and smother invading hornetsJuly 5th, 2009 LONDON - Honeybee hordes form "bee balls" to mob and smother their predators, giant hornets, killing them within 10 minutes of trapping, scientists have observed. According to the journal Naturwissenschaften, honeybees use heat and carbon dioxide as part of their mechanism to guard themselves from their natural enemies.
Space viruses may have not seeded life on EarthJune 2nd, 2009 LONDON - A new study has determined that life on Earth is unlikely to have come from space viruses. Panspermia is the idea that life was seeded by extraterrestrial microbes in the form of hardy bacterial spores that hitched a ride on a space rock and landed on Earth.
Battery that runs on air unveiledMay 20th, 2009 LONDON - British scientists have unveiled a revolutionary battery that runs on air. By sucking in oxygen that reacts with carbon inside, the super-cell recharges itself.he invention will pave the way for a new generation of electric cars, inventors at Scotland's University of St Andrews said, reports The Sun.
New laser technique reveals actual photosynthesis, frame by frameFebruary 6th, 2009 LONDON - Researchers have clicked for the first time, images showing how the sun's energy moves inside plants - a practical demonstration of photo-synthesis, the most efficient solar energy process on earth. Inside a photosynthetic protein, the sun's energy is efficiently guided across the molecule to drive a chemical reaction that stores energy as food and takes in carbon dioxide.
