Locusts can detect cancer in humans

Posted by in categories: biotech/medical, chemistry, engineering, neuroscience

A new study led by Michigan State University (MSU) has found that locusts can reliably detect through smell a variety of human cancers. The insects can not only “smell” the difference between healthy and cancerous cells, but they can also distinguish between different cancer cell lines. These findings could provide a basis for devices which use locust sensory neurons to enable the early detection of cancer by using only biomarkers in a patient’s breath.

“Noses are still state of the art,” said study senior author Debajit Saha, an assistant professor of Biomedical Engineering at MSU. “There’s really nothing like them when it comes to gas sensing. People have been working on ‘electronic noses’ for more than 15 years, but they’re still not close to achieving what biology can do seamlessly.”

The dark matter hypothesis isn’t perfect, but the alternatives are worse

Posted by in categories: computing, cosmology, particle physics, satellites

But the dark matter hypothesis isn’t perfect. Computer simulations of the growth of galaxies suggest that dark-matter-dominated galaxies should have incredibly high densities in their centers. Observations of real galaxies do show higher densities in their cores, but not nearly enough as those simulations predicted. Also, simulations of dark matter evolving in the universe predict that every galaxy should have hundreds of smaller satellites, while observations consistently come up short.

Given that the dark matter hypothesis isn’t perfect — and that we have no direct evidence for the existence of any candidate particles — it’s worth exploring other options.

Cancer Patient Receives World First 3D Printed Titanium Jaw

Posted by in category: biotech/medical

The jawbone was reconstructed from the patient’s 3D MRI and CT scans, making it a perfect fit in its new boney home.

This is a major step in the treatment of head and neck cancer, a disease which affects as many as 600,000 people every year. For most people, especially those whose cancer is caught early, the treatment is fairly minimal surgery, sometimes using lasers, or radiation therapy.

For some, though, more aggressive action is needed, and part of the lower jaw must be removed. As you might expect, this can have a massive impact on the patient’s life, since it renders them unable to speak, chew, and other essential actions – not to mention being quite noticeable from an aesthetic viewpoint.

New mapping method could aid exploration of moon, Mars and beyond

Posted by in categories: mapping, mathematics, space

Researchers find mathematical trick to combining planetary surface data.

Researchers have discovered a method for making high-resolution maps of planetary surfaces like the moon’s by combining available imagery and topography data.

Mapping the complex and diverse surface of a world like the moon in detailed resolution is challenging because laser altimeters, which measure changes in altitudes, operate at much lower resolution than cameras. And although photographs offer a sense of surface features, it’s difficult to translate images into specific heights and depths.

Switzerland’s new energy asset: hydro plant with capacity to charge 400,000 car batteries

Posted by in categories: energy, transportation

FINHAUT, Switzerland — Switzerland is adding a much needed cog in the wheel to its energy supply with an underground hydropower plant that says it has capacity to store enough electricity to charge 400,000 car batteries simultaneously.

Developers of the 2.2 billion Swiss franc ($2.30 billion) Nant de Drance plant in the canton of Valais, which came online in July, say the facility operates like a giant battery.

Its six turbines tucked in a cavern 600 metres below ground between the Emosson and Vieux Emosson reservoirs have capacity of 900 MW, making it one of the most powerful pumped storage plants in Europe.

Hall-Effect Thruster Utilizing Bismuth as Propellant

Posted by in category: space travel

Circa 2008

Marshall Space Flight Center.

A laboratory-model Hall-effect spacecraft thruster was developed that utilizes bismuth as the propellant. Xenon was used in most prior Hall-effect thrusters. Bismuth is an attractive alternative because it has a larger atomic mass, a larger electron-impact-ionization cross-section, and is cheaper and more plentiful.
