Glowing Tumor Technology Helps Surgeons Remove Hidden Cancer Cells

Surgeons were able to identify and remove a greater number of cancerous nodules from lung cancer patients when combining intraoperative molecular imaging (IMI) – through the use of a contrast agent that makes tumor cells glow during surgery – with preoperative positron emission tomography (PET) scans. The study from the Abramson Cancer Center at the University of Pennsylvania (ACC) is the first to show how effective the combination of IMI with the tumor-glowing agent can be when combined with traditional PET imaging. Researchers published their findings today in Annals of Surgery.

Biochar could clear the air in more ways than one

Biochar from recycled waste may both enhance crop growth and save health costs by helping clear the air of pollutants, according to Rice University researchers.

Galactic David and Goliath

The gravitational dance between two galaxies in our local neighbourhood has led to intriguing visual features in both as witnessed in this new NASA/ESA Hubble Space Telescope image. The tiny NGC 1510 and its colossal neighbour NGC 1512 are at the beginning of a lengthy merger, a crucial process in galaxy evolution. Despite its diminutive size, NGC 1510 has had a significant effect on NGC 1512’s structure and amount of star formation.

Climate change to push Ethiopian coffee farming uphill

Relocating coffee areas, along with forestation and forest conservation, to higher altitudes to cope with climate change could increase Ethiopia‘s coffee farming area fourfold, a study predicts.

Heavy metals in water meet their match

Carbon nanotubes immobilized in a tuft of quartz fiber have the power to remove toxic heavy metals from water, according to researchers at Rice University.

Prize-winning filters produced in the lab of Rice chemist Andrew Barron by then-high school student and lead author Perry Alagappan absorb more than 99 percent of metals from samples laden with cadmium, cobalt, copper, mercury, nickel and lead. Once saturated, the filters can be washed with a mild household chemical like vinegar and reused.

The researchers calculated one gram of the material could treat 83,000 liters of contaminated water to meet World Health Organization standards — enough to supply the daily needs of 11,000 people.

Scientists develop new supplement that can repair, rejuvenate muscles in older adults

Whey protein supplements aren’t just for gym buffs according to new research from McMaster University. When taken on a regular basis, a combination of these and other ingredients in a ready-to-drink formula have been found to greatly improve the physical strength of a growing cohort: senior citizens.

The deterioration of muscle mass and strength that is a normal part of aging –known as sarcopenia—can increase the risk for falls, metabolic disorders and the need for assisted living, say researchers.

Cave bacteria: A window to the past, even to distant worlds

Each time she looks through a microscope to better understand cave bacteria, Richenda McFarlane may also be staring at life that’s centuries old or perhaps even something from another planets.

She’s getting to play researcher, time traveler and astronaut all at the same time.

Atomic Movies May Help Explain Why Perovskite Solar Cells Are More Efficient

In recent years, perovskites have taken the solar cell industry by storm. They are cheap, easy to produce and very flexible in their applications. Their efficiency at converting light into electricity has grown faster than that of any other material – from under four percent in 2009 to over 20 percent in 2017 – and some experts believe that perovskites could eventually outperform the most common solar cell material, silicon. But despite their popularity, researchers don’t know why perovskites are so efficient.

Now experiments with a powerful “electron camera” at the Department of Energy’s SLAC National Accelerator Laboratory have discovered that light whirls atoms around in perovskites, potentially explaining the high efficiency of these next-generation solar cell materials and providing clues for making better ones.

On International Day, UN spotlights threatened coastal mangrove ecosystems

Coastal mangroves are among the most imperiled ecosystems on earth, with current estimates indicating that up to 67 per cent have been lost to date – according to the United Nations science wing.

“The stakes are high, because mangrove ecosystems provide benefits and services that are essential for life,” said Irina Bokova, Director-General of the UN Educational, Scientific and Cultural Organization (UNESCO) in a message on the International Day for the Conservation of the Mangrove Ecosystem.

The World Lost a Nebraska-Sized Chunk of Forest in 2015

The world lost nearly 49 million acres of forest in 2015 to logging, wildfires, palm oil plantations, and other development activity, according to new data by the conservation group Global Forest Watch. That is equal to an area roughly the size of Nebraska, Climate Central reported.
