How a shocking environmental disaster was uncovered after 70 years

Posted by in category: futurism

I saw this on several sites and it both infuriates me and makes me really sad. A half million barrels of DDT dumped right off the california coast in the 1940s, about 3k meters below on seafloor. Metal barrels corrode fast in salt water so you can assume its been poisoning the plankton and fish all this time.


The lasting effects of DDT contamination are killing an alarming number of California sea lions.

Researchers create light waves that can penetrate even opaque materials

Posted by in categories: biotech/medical, materials

This method of finding light patterns that penetrate an object largely undisturbed could also be used for imaging procedures. “In hospitals, X-rays are used to look inside the body—they have a shorter wavelength and can therefore penetrate our skin. But the way a light wave penetrates an object depends not only on the wavelength, but also on the waveform,” says Matthias.


Why is sugar not transparent? Because light that penetrates a piece of sugar is scattered, altered and deflected in a highly complicated way. However, as a research team from TU Wien (Vienna) and Utrecht University (Netherlands) has now been able to show, there is a class of very special light waves for which this does not apply: for any specific disordered medium—such as the sugar cube you may just have put in your coffee—tailor-made light beams can be constructed that are practically not changed by this medium, but only attenuated. The light beam penetrates the medium, and a light pattern arrives on the other side that has the same shape as if the medium were not there at all.

This idea of “scattering-invariant modes of ” can also be used to specifically examine the interior of objects. The results have now been published in the journal Nature Photonics.

Aubrey de Grey talks about putting aging under medical control (con S/T en Español)

Posted by in categories: biotech/medical, life extension

Aubrey de Grey’s talk during the South Summit that took place in Spain last October 2020. Aubrey explains why he thinks science and technology is close to bringing aging under complete medical control.

He also describes how along the process we will reach what he calls “Longevity Escape Velocity”. Once we reach it, we will be able to stay one step ahead of the curve of aging, and extend significantly, eventually indefinetely, human health and lifespan.

Northrop Grumman robotic MEV-2 spacecraft, in a first, catches active Intelsat satellite

Posted by in categories: business, robotics/AI, satellites

Two aerospace firms accomplished an industry first on Monday, as a small Northrop Grumman spacecraft docked successfully with an active Intelsat satellite to provide service and extend its life.

Intelsat’s IS-10–02 satellite is nearly 18 years old, and operating well past its expected lifespan, but the Northrop Grumman-built spacecraft called MEV-2 will add another five years of life to IS-10–02, essentially re-fueling the satellite and giving it a new engine for control.

The companies hit a milestone in the growing business of servicing satellites while in space.

Astronomers Sketch U Monocerotis – A Rare Type of Stellar Binary – Using Over a Century of Observations

Posted by in category: space

Astronomers have painted their best picture yet of an RV Tauri variable, a rare type of stellar binary where two stars – one approaching the end of its life – orbit within a sprawling disk of dust. Their 130-year dataset spans the widest range of light yet collected for one of these systems, from radio to X-rays.

“There are only about 300 known RV Tauri variables in the Milky Way galaxy,” said Laura Vega, a recent doctoral recipient at Vanderbilt University in Nashville, Tennessee. “We focused our study on the second brightest, named U Monocerotis, which is now the first of these systems from which X-rays have been detected.”

Study reveals neural stem cells age rapidly

Posted by in categories: biotech/medical, engineering, life extension, neuroscience

In a new study published in Cell Stem Cell, a team led by USC Stem Cell scientist Michael Bonaguidi, Ph.D., demonstrates that neural stem cells—the stem cells of the nervous system—age rapidly.

“There is chronological aging, and there is , and they are not the same thing,” said Bonaguidi, an Assistant Professor of Stem Cell Biology and Regenerative Medicine, Gerontology and Biomedical Engineering at the Keck School of Medicine of USC. “We’re interested in the biological aging of neural stem cells, which are particularly vulnerable to the ravages of time. This has implications for the normal cognitive decline that most of us experience as we grow older, as well as for dementia, Alzheimer’s disease, epilepsy and .”

In the study, first author Albina Ibrayeva, a Ph.D. candidate in the Bonaguidi Lab in the Eli and Edythe Broad Center for Regenerative Medicine and Stem Cell Research at USC, joined her colleagues in looking at the brains of young, middle-aged and .

Ingenuity Mars Helicopter failed high-speed spin test causing reschedule of the first flight

Posted by in categories: computing, space

On April 10, 2021 NASA announced Ingenuity Mars Helicopter failed high-speed spin test causing reschedule of the first flight to no earlier than April 14. NASA explained that during a high-speed spin test of the rotors on Friday, the command sequence controlling the test ended early due to a “watchdog” timer expiration. This occurred as it was trying to transition the flight computer from ‘Pre-Flight’ to ‘Flight’ mode. The helicopter is safe and healthy and communicated its full telemetry set to Earth. The watchdog timer oversees the command sequence and alerts the system to any potential issues. It helps the system stay safe by not proceeding if an issue is observed and worked as planned. Ingenuity team is reviewing telemetry to diagnose and understand the issue. Following that, they will reschedule the full-speed test.
