Recycling is not enough -- we need to consume less

...dies Institute, describes international efforts to become more resource efficient by significantly reducing waste or achieving higher rates of recycling or reuse. He says that despite recent improvements the UK is still a long way behind the best performing countries and regions where taxation and household...

The kapok connection -- Study explains rainforest similarities

...to survive an oceanic voyage and then successfully become established elsewhere, such improbable events become probable over 10 to 15 million years." Dick studied the rainforest form of Ceiba pentandra, a spec...

Cancer stem cells similar to normal stem cells can thwart anti-cancer agents

... cells, called cancer stem cells, which ultimately become the source of disease recurrence and eventual metastasis. Now, research by scientists at the University of Pittsburgh School of Medicine suggests that for chemotherapy to be truly effective in treating lung cancers, for example, it must be able to ta...

Research finds that circadian rhythms dominate all life functions

... regular periods of day and night. Oscillation can become chaotic in states of consistent lighting or lack of lighting, but it never stops. Comparing the complex system in which the genes function to an AC power grid, Ptitsyn made the discovery by plotting the expression of 20,000 genes on a scale of freque...

In nature, proteins sweep up nanoparticles

...icles in their tracks, as this process does, could become a critical component of a bioremediation strategy, if only scientists understand how it works. To explore this question, the team turned to Berkeley Labs Advanced Light Source, a national user facility that generates intense light for scientific re...

Book makes case for using evolution in everyday life

...hamton University, is convinced that evolution can become more widely accepted once its consequences for human welfare are appropriately understood. "When evolution is presented as unthreatening, explanatory, and useful, it can be easily grasped and appreciated by most people, regardless of their religiou...

Pre-cancerous blood diseases can be products of their environment

...e marrow microenvironment can make the blood cells become abnormal, like a type of pre-leukemic disease, said Louise Purton, who is affiliated with Peter MacCallum Cancer Centre in Australia, Massachusetts General Hospital, and the Harvard Stem Cell Institute. Such pre-cancerous conditions are often difficu...

Screening approach leads to discovery of gene linked to breast cancer

...m, proteins called MEK or PI3K. When both of these become active at the same time, cells become cancerous, investigators found. The team then created a set of 354 human kinases and injected eac...

Rove beetles act as warning signs for clear-cutting consequences

...re mature forest species, such as the rove beetle, become threatened by fragmentation and loss of habitat. This study is significant because it indicates a new forest will not hold the same biota as an old forest, so we must ensure that forest managers conserve adequate patches of old forests or make adequa...

Food safety begins as vegetables grow

Barak and other APS members will present their latest food safety research and describe future research needs at a symposium titled "Cross Domain: Emerging Threats to Plants, Humans, and Our Food S...

Now, self-healing materials can mimic human skin, healing again and again

...cation, however, the supply of healing agent would become exhausted, said Scott White, a Willett Professor of aerospace engineering and a researcher at the Beckman Institute. In our new circulation-based approach, there is a continuous supply of healing agent, so the material could heal itself indefinitely....

Undergraduate research shows leaderless honeybee organizing

This interaction is a behavior that nobody had described before, Schneider said. Contrary to the popular conception of a colony con...

Researchers examine carbon capture and storage to combat global warming

While solar power and hybrid cars have become popular symbols of green technology, Stanford researchers are exploring another path for cutting emissions of carbon dioxide, the leading greenhouse gas that causes global warming. Carbon capture and storage, also called carbon sequestration, traps...

It is at this stage that textbooks say chromosomes are shortest. Then, after separating they would expand again, says Ellenberg. But we found something ve...

University of Liverpool launches 10 million small animal teaching hospital
