NASA: Nearby ocean worlds could be best bet for life beyond Earth

Posted by in category: space

Fascinating stuff!

NASA has new evidence that the most likely places to find life beyond Earth are Jupiter’s moon Europa or Saturn’s moon Enceladus. In terms of potential habitability, Enceladus particularly has almost all of the key ingredients for life as we know it, researchers said.

New observations of these active ocean worlds in our solar system have been captured by two NASA missions and were presented in two separate studies in an announcement at NASA HQ in Washington today.

Synopsis: A Room-Sized Linear Accelerator for Proton Therapy

Posted by in category: biotech/medical

A proton beam can kill cancer cells, and the accelerators used for treatment are always the circular kind. Linear accelerators (“linacs”) allow more control of the beam; for example, the energy can be varied rapidly to match a patient’s breathing. But linacs take up a lot of space. Now researchers propose a design that could fit in a room 10 m x 20 m, potentially making linacs practical for patient therapy. Research from CERN.

NASA’s New Horizons Surprises With Whole New View Of Cosmos

Posted by in category: space travel

New Horizons has made observations it was never tasked with making; serendipity of the sort that may lead to new and better astronomical missions to observe the distant cosmos from the outer fringes of the solar system, where it’s darkest and astronomers would have the clearest, dust-free view of our own galaxy and the optical light from the universe as a whole.

NASA’s New Horizons spacecraft has unexpectedly made observations of optical light from beyond our Milky Way galaxy. Astronomers are ecstatic and hoping for more.

Climate change, other concerns fuel scientists’ in-your-face activism

Posted by in categories: biotech/medical, government, sustainability

While many scientists have shied away from explicitly political actions in recent decades, the community throughout history has spoken publicly on a wide variety of social, technological and ideological issues.

That has included everything from opposing fascism, nuclear proliferation and the Vietnam War to sitting on government panels that advise elected leaders on stem-cell research involving human embryos.

In U.S. history, scientists have been vocal about fascism, nuclear proliferation, the Vietnam War, stem cells and more.

The gravity and light-sucking monster weighs as much as 4 million suns

Posted by in category: cosmology

AFTER training a network of telescopes stretching from Hawaii to Antarctica to Spain at the heart of our galaxy for five nights running, astronomers said Wednesday they may have snapped the first-ever picture of a black hole.

It will take months to develop the image, but if scientists succeed the results may help peel back mysteries about what the universe is made of and how it came into being.

“Instead of building a telescope so big that it would probably collapse under its own weight, we combined eight observatories like the pieces of a giant mirror,” said Michael Bremer, an astronomer at the International Research Institute for Radio Astronomy (IRAM) and a project manager for the Event Horizon Telescope.

The endgame for cameras is having no camera at all

Posted by in categories: computing, internet, mobile phones

I’ve been reading about Gcam, the Google X project that was first sparked by the need for a tiny camera to fit inside Google Glass, before evolving to power the world-beating camera of the Google Pixel. Gcam embodies an atypical approach to photography in seeking to find software solutions for what have traditionally been hardware problems. Well, others have tried, but those have always seemed like inchoate gimmicks, so I guess the unprecedented thing about Gcam is that it actually works. But the most exciting thing is what it portends.

I think we’ll one day be able to capture images without any photographic equipment at all.

New Artificial Organ Can Be Implanted in the Body to Create Cancer-Fighting Cells

Posted by in category: biotech/medical

  • Researchers at UCLA have created an artificial thymic organoid that generates its own cancer-fighting T cells.
  • While it has not been tested in humans yet, this artificial organ could reduce the time and cost of T cell immunotherapy and make it a more viable option for patients with low white-blood cell counts.

Many artificial organs are being developed as an alternative to donated organs, which are only temporary solutions that require the recipients to maintain a lifetime regiment of medications. With recent advancements in biomedical technologies, the time may be coming when those who require transplants no longer need to wait on donation lists to replace organs like kidneys and blood vessels. And now, scientists have added the thymus to the list of body parts we can artificially simulate.

The thymus is a gland that is essential to your immune system. T cells, a type of white blood cell that helps to get rid of viruses, bacterial infections, and cancer cells, mature within this gland. When people get sick (or as they age), the thymus becomes worse at its job. In some cases, people with different types of cancer are not getting the biological support and help they need from their T cells.

Gene editing opens doors to seedless fruit with no need for bees

Posted by in categories: bioengineering, biotech/medical, genetics

Gene-edited seedless tomatoes don’t need pollinating to produce fruit – which could come in useful at a time when bees are on the decline.
