The World Meteorological Organization’s State of the Climate in Asia 2024 report warns that the region is warming nearly twice as fast as the global average, driving more extreme weather and posing serious threats to lives, ecosystems, and economies. In 2024, Asia experienced its warmest or second warmest year on …
An unusual, plant-like bacteria capable of a type of photosynthesis is available in far more numbers in the ocean than previously y assumed. The discovery adds a new component to the ocean's carbon cycle, which is a major contributor to the Earth's carbon cycle on which all life depends. The …
Researchers at the Carnegie Institution of Washington, USA and the Martek Biosciences Corporation of Columbia, have devised a way to make one species of single-celled algae grow without light. By inserting a single gene from human red blood cells in one case and another single-celled algae in another, the researchers …
instead of people digging and dumping waste, an army of microorganisms could soon be cleaning up more than 200,000 hectares of contaminated industrial sites in the uk . The uk government has launched a us $21.4 million research program, which will use microorganisms and bacteria to reverse the damage done …
yeast growing on a medium can look beautiful. But some fungi can be dangerous. In the human body, they can coat medical implants with thin films causing serious complications in patients with hip and valve replacements. In fact, every year thousands of deaths can be traced to fungal infection formations …
antibacterial agents in liquid and solid soaps may create stronger bacteria instead and cause harm in the long run. This was revealed during a research survey done by Eli N Perencevich, a research fellow for infectious diseases at the Beth Israel Deaconess Medical Center in Boston, usa , and his …
It's a medical equivalent of tracking a pathological killer and his method. US-based researchers have sequenced the genome of a potentially deadly strain of Escherichia coli 0157 , a bacterium that causes a variety of ailments, like urinary tract infections , diarrhoea and neonatal meningitis. It is mainly transmitted through …
scientists have imitated a key process that might have triggered the beginning and end of the ice ages and also could solve the present day problem of carbon emissions. An international team of scientists working on the Southern Ocean Iron Release Experiment ( soiree ) has "fertilised' a part of …
ancient bacteria trapped in a salt crystal for 250 million years are the world's oldest living beings, claims a team of microbiologists led by Russell Vreeland of the West Chester University, Pennsylvania, usa . The microscopic creatures are ten times older than any living organism known to humankind. The researchers …
punjab durrie weavers ( pdw ), a non-governmental organisation, operating from Chandigarh and Mumbai, is collecting information on dyes available from plants and microbes. pdw intends to utilise traditional knowledge to encourage cultivation of such plants on marginal lands. Chemical dyes pollute. Alternative dyeing pigments, extractable from plants and microbes, …
Surveillance of bacterial susceptibility to five antimicrobial agents was performed during a 1-year period in and around four freshwater fish farms situated along a stream in western Denmark. Besides assessing the levels of antibiotic resistance among the culturable fraction of microorganisms in fish, water, and sediment samples, two major fish …
The fungus Armillaria ostoyae , commonly called the honey mushroom, has grown so extensively in Malheur National Forest, usa , that it has become the largest living organism ever found. The fungal spore seems to have germinated approximately 2,400 years ago and now covers an area of 890 hectares and …
a team of scientists at Ohio University in the us is working on technology that uses algae, sunlight and the natural process of photosynthesis to absorb carbon dioxide ( co 2 ) from the combustion of coal. The result: reduced greenhouse gas emissions. co 2 has been identified as the …
australian government will use a fungus to fight a weed, which has destroyed vast areas of the country's natural bushland. The Commonwealth Scientific and Industrial Research Organisation and the Weeds Cooperative Research Centre have released the rust fungus, Puccinia myrsiphylli , in order to stop the uncontrollable spread of the …
A TEAM of American scientist have decoded the genetic sequence of the bacterium, Vibrio cholerae. The sequence of El Tor, a destructive type of cholera bacterium, was deciphered by John Hedelberg of the Institute for Genomic Research in Rockville, Maryland, Rita Colwell of University of Maryland in Baltimore and John …
an algae , responsible for large-scale destruction of European sea habitats, has been discovered in Agua Hedionda near San Diego, usa . "The algae ( Caulerpa taxifolia ) destroys the water bed and kills the flora and fauna," says Bob Hoffmann, southern California environmental coordinator for the National Marine Fisheries …
It is now well-known that albatrosses use smell to find food and navigate the oceans. Now a new study has found that they are sensitive to odours in the air released by krill and phytoplankton living beneath the wavers. Gabrielle Nevitt of the University of California studied the behaviour of …
Sponges found in the chilly waters of Antarctica are infested with algae that scrounge off them during the dark polar winter. Algae often live inside the cells of other animals, such as reef-building corals, but they usually provide some benefit. Giorgio Bavestrello of the University of Ancona and his colleagues …
many organisms, such as bacteria and a variety of microbes, live as single cells. Others live in groups, and the cells that make up our bodies constitute a good example of these. In either case, a cell has to be able to sense its surroundings if it is to get …
