The power of one: A simpler, cheaper method for cell fusion

...d up. "We are not saying that our technology is necessarily better, but it is definitely cheaper and has other benefits," he said. "Hopefully, with our technology many more scientists will be able to experiment with the procedure. I believe that could open up a lot of exciting research opportunities." Lu d...

Cracking the egg

Sexual reproduction is not necessarily sexy (especially when scientists start analyzing it), but it is fascinating. As we all know, the basics entail bringing together an egg and a sperm, a whole lot of cell division and growth, and sooner or later a young organism that carries a mix of g...

Global map shows new patterns of extinction risk

...ation of endangered species from one group, do not necessarily have high numbers from the others. This new finding has far-reaching implications for conservation planning by governments and NGOs, and their decisions about where to focus conservation spending. These decisions have typically been based on the assu...

Microbes compete with animals for food by making it stink

...on to the various forms of the bait, but it didn't necessarily test feeding, Hay noted. "It could be that the rotten food is just as good, but a lot of the good smells have leached out in the water, so maybe it's just food that's harder for predators to find," he explained. Researchers assessed their question...

Endangered shortnose sturgeon saved in Hudson River

...ndangered in other rivers, Bain said, and will not necessarily be removed from the endangered species list by the U.S. government. In the past 100 years, 27 species of fish have been died out in North America and four have become extinct. The U.S. government currently protects 149 fish species and subspecies a...

Biologists call for better choice of model organisms in 'evo-devo'

...c spread is nice to show diversity, but it doesn’t necessarily lead to new general insights about evolution. "...species further down the evolutionary line are not necessarily increasingly different from that common ancestor. "Among living species that descended from a par...

Anti-herpes treatment reduces HIV levels in women infected with both viruses

...s are not always successful, as knowledge does not necessarily translate into sexual behaviour change. Therefore, innovative methods that target the biological susceptibility of individuals to acquire or transmit HIV are also required. A number of options to prevent HIV transmission are currently being investiga...

Antibody signal may redirect inflammation to fuel cancer

...treating people with HIV. The goal would not be to necessarily eliminate every last cancer cell, but to control the inflammation process needed for the cancer to progress to a more threatening stage. The new UCSF finding comes from studies with mice genetically engineered to carry some of the genes of the hu...

Long-lived deep-sea fishes imperiled by technology, overfishing

Failure to meet United Nations sanitation target could affect millions of the world's poorest

...d sanitation, Davis said. However, wealth does not necessarily translate into improved water and sanitation services. "Tracking the progress of countries from 1990 to 2004, we do see that countries that are at risk of missing either or both targets are more likely to be in the lowest income categories," she said...

Microbes start immune response by sneaking inside cells

...cells that are the body’s front-line defense don’t necessarily rest quietly until invading bacteria lock onto receptors on their outside skins and rouse them to action, as previously thought. In a new paper, University of Michigan scientists describe their findings that bacteria can barge inside these guard cell...

New technologies coming too fast for Indian farmers

...y ask their neighbors. Copying your neighbor isn't necessarily a bad thing; but in this case, everyone is copying everyone else, which results in fads, not testing." Stone argues that the previously undocumented pattern of fads, in which each village moves from seed to seed, reflects a breakdown in "environmenta...

NASA predicts nongreen plants on other planets

...that photosynthesis on extrasolar planets will not necessarily look the same as on Earth. "It makes one appreciate how life on Earth is so intimately adapted to the special qualities of our home planet and Sun," said Kiang. ...

Study finds antibiotic resistance in poultry even when antibiotics were not used

...eveloping in their eggs. "The resistances don't necessarily come from antibiotic use in the birds that we eat," Lee said, "so banning antibiotic use on the farm isn't going to help. You have to put in some work before that." Lee and her team sampled droppings from more than 140,000 birds under four differe...

Cloning the smell of the seaside

...sulphide. And secondly, because inhaling it is not necessarily good for you." DMS is a little known but important gas. Across the world's oceans, seas and coasts, tens of millions of tonnes of it are released by microbes that live near plankton and marine plants, including seaweeds and some salt-marsh plants....

Dual-imaging technique useful before -- and during -- brain surgery

Snoring in children might be an allergic type disease

...re serious sleep-disordered breathing, so it’s not necessarily a harmless condition,” Dr Marshall added. “In adults habitual snoring is seen as being caused by anatomical problems in the airway or obesity. But in children it seems that snoring is much more closely related allergy and inflammation”. “Our data ...
