[1810.11490] Could Solar Radiation Pressure Explain ‘Oumuamua’s Peculiar Acceleration?

Posted by in categories: physics, space

The news we had finally found ripples in space-time reverberated around the world in 2015. Now it seems they might have been an illusion.

LIGO’s detectorsEnrico Sacchetti

THERE was never much doubt that we would observe gravitational waves sooner or later. This rhythmic squeezing and stretching of space and time is a natural consequence of one of science’s most well-established theories, Einstein’s general relativity. So when we built a machine capable of observing the waves, it seemed that it would be only a matter of time before a detection.

Optimizing network software to advance scientific discovery

Posted by in categories: mathematics, particle physics, supercomputing

High-performance computing (HPC)—the use of supercomputers and parallel processing techniques to solve large computational problems—is of great use in the scientific community. For example, scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory rely on HPC to analyze the data they collect at the large-scale experimental facilities on site and to model complex processes that would be too expensive or impossible to demonstrate experimentally.

Modern science applications, such as simulating , often require a combination of aggregated computing power, high-speed networks for data transfer, large amounts of memory, and high-capacity storage capabilities. Advances in HPC hardware and software are needed to meet these requirements. Computer and computational scientists and mathematicians in Brookhaven Lab’s Computational Science Initiative (CSI) are collaborating with physicists, biologists, and other domain scientists to understand their data analysis needs and provide solutions to accelerate the scientific discovery process.

Watch a Pack of Boston Dynamics’ Creepy Robot Dogs Pull a Truck

Posted by in categories: robotics/AI, transportation

Step aside, reindeer — robot dogs are hauling this load.

In an ominous video titled “Mush, Spot Mush!” posted on YouTube Tuesday, robot maker Boston Dynamics showed off the sheer strength of its SpotMini quadripedal robot dog. The clip shows 10 specialized Spotmini derivatives called Spotpower hauling a box truck across a parking lot — and at a one degree incline.

Study finds diabetes drug may prevent, slow kidney disease

Posted by in category: biotech/medical

A drug that’s used to help control blood sugar in people with diabetes has now been shown to help prevent or slow kidney disease, which causes millions of deaths each year and requires hundreds of thousands of people to use dialysis to stay alive.

Doctors say it’s hard to overstate the importance of this study, and what it means for curbing this problem, which is growing because of the obesity epidemic.

The study tested Janssen Pharmaceuticals’ drug Invokana. Results were discussed Sunday at a medical meeting in Australia and published by the New England Journal of Medicine.

Liquid Democracy

Posted by in category: futurism

Liquid democracy is a technologically enabled and scalable hybrid of direct and representative democracy.[2] Liquid Democracy, a subset of Delegative Democracy, is a powerful voting model for collective decision making in large communities. Liquid Democracy combines the advantages of Direct Democracy and Representative Democracy and creates a truly democratic voting system that empowers voters to either vote on issues directly, or to delegate ones voting power to a trusted party.[3]

Superdemocracy upholds the concept of delegated voting, via systems such as “liquid democracy”. This enables citizens to delegate their votes in specified areas of debate to people whom they trust in these areas. In case someone changes their mind, delegations can be revoked or reassigned at any time.

Liquid democracy is a tech-enabled improvement to those parliamentary systems in which a single elected member of parliament is meant to represent the voter in all areas of debate. With liquid democracy, representation is no longer an all-or-nothing affair. Accordingly, liquid democracy moves away from the unhelpful fiction that politicians are supposed to have been elected to carry out every nook and cranny of their election manifesto. It enables a set of approvals and affirmations that is much more fine-grained — an ongoing dynamic conversation with nuance and inventiveness.”

Liquid Blood Extracted From 42,000-Year-Old Foal Found Frozen in Siberia

Posted by in categories: biotech/medical, neuroscience

Scientists in the Yakutsk region of Siberia have managed to extract samples of liquid blood from a 42,000-year-old foal that was found embedded in permafrost back in 2018. The scientists are hoping to collect viable cells for the purpose of cloning the extinct species of horse.

The male foal was discovered in the Batagaika depression on August 11, 2018. Permafrost left the remains in remarkably good shape, raising hopes that its cells could be extracted. The specimen is thought to belong to an extinct species of horse known as Lenskaya breed (also known as the Lena horse), as the Siberian Times reported last year.
