Mutating the entire genome

...ein made by Cre acts like a knife, cutting the DNA wherever loxP is found. The offspring mouse, in turn, is bred with a normal mouse. In a remarkably high average of 10 percent of the offspring, the desired large stretch of DNA is either deleted or duplicated so scientists can see what goes wrong in the mu...

Recycling is not enough -- we need to consume less

...considering the achievements of existing practice, wherever in the world that may be found. For example: We should set a per capita residual waste target to drive both recycling and prevention, backed up by variable charging of householders. We should be among the first countries to tackle consu...

Mucosal-surface immune function discoveries could boost vaccine research

...s found in high concentrations along mucosal sites wherever friendly, "commensal" bacteria abound, such as in the intestine where these germs aid in digestion. "Of course, left unchecked, even these bacteria could overrun the gut and cause harm," Dr. Cerutti says. "But somehow the immune system keeps them in ...

Nanocomposite labeled cancer cells can be targeted and destroyed using lasers

...absorption can be selectively and locally enhanced wherever composite nanodevices are present. Irradiation of the mix of labeled and unlabeled cells by laser light, causes tiny bubbles to form that disrupt and damage the labeled cells, but leave unlabeled cells unaffected. This technology holds promise as an ...

Build parks to climate proof our cities

...ies need to be taken to increase green space cover wherever structural changes are occurring within urban areas, as well as planting street trees or developing green roofs." The research, published in Built Environment, also examined the effect increased green space would have on the amount of rainwater urb...

New deep-sea hydrothermal vents, life form discovered

...ssels from the vent area. According to Von Damm, wherever there are mid-ocean ridges, scientists frequently find geothermal vents warmed by heat energy from underlying volcanic conduits. "Each new vent sparks fresh excitement, because each one is different. Every vent has a different chemistry, and that h...

UN, industry, others partner to create world standards for e-scrap recycling, harvesting components

"HP has joined StEP to help countries work through the many legal, scientific and practical issues involved in managing e-waste, treatment standards, and innovative design to maximize re-use and rec...

How do marine turtles return to the same beach to lay their eggs?

... maintain their course towards the egg-laying site wherever they find themselves. It is almost as if they were equipped with a compass pointing towards the beach in question. So they can correct any deflection they are subject to: transport by boat, ocean currents But, unlike human navigators, they are not ab...

Antarctic marine explorers reveal first biological changes after collapse of polar ice shelves

Nitrogen study may improve ecological predictions

...attern of nitrogen release is pretty much the same wherever it occurs, and is driven primarily by the initial concentration of nitrogen present in the decaying plant material. It has little to do with location, soil types, microbes present, or other factors. The speed of the process is affected by climate, pa...

"Our study will help provide insight into how microorganisms manage to survive in these conditions." Funded with a two-year, $481,000 National Science Foundation grant, Lanoil will be working with colleag...

Hofmeyr skull supports the 'Out of Africa' theory

A new approach to dating developed by Grine team member Richard Bailey and his colleagues at Oxford University allowed t...

Roadworks on the motorways of the cell

Researchers from the European Molecular Biology Laboratory (EMBL) have discovered for the first time that a protein stabilises microtubules by binding to their w...

Embryonic patterning makes the feathers fly

..., will appear on the skin of the developing embryo wherever fibroblast growth factor (FGF) is activated. The mystery has been how a pattern of activation was laid down by FGF. Speculation pointed to a downstream cellular signaling pathway but which one (and if it was just one pathway) was unknown. To disce...

Earliest fungi may have found multiple solutions to propagation on land, new study infers

According to Vilgalys, what makes a fungus a fungus is not the way it propagates but how it feeds. Am...

A general understanding of this behavior and the development of a new scientific method for studying this phenomenon may lead to better understanding of variou...

UCSD biologists solve plant growth hormone enigma

...held view was that auxin could just be transported wherever it was needed. Not so, because turning auxin off in specific tissues of the plant led to defects in those tissues, while the rest of the plant appeared normal. "Knowing which auxin genes are activated when should make it possible to modify plant ...
