How Animals Code Their Kids for Survival
Posted by Xavier Rosseel in category: genetics
It turns out the capacity for offspring to benefit from their parents’ experiences doesn’t just happen with fish. Munday tells me about Daphnia, often called water fleas, that are found in freshwater lakes, ponds, and puddles. The tiny crustacean can hatch with either a round head or a pointed head. If it shares the water with predators such as fish or midges or other insects, spikes and spines help lessen the likelihood of being eaten. For many species of juvenile water flea…
Insights into epigenetics and inheritance show that some organisms can adapt to a changing world.

NMN Improves Cognitive Function in Aged Mice
Posted by Steve Hill in categories: biotech/medical, life extension, neuroscience
Researchers have tested nicotinamide mononucleotide on aged mice to see if it can help reverse age-related cognitive decline by improving blood flow in the brain.
The brain is a hungry organ
Healthy brain function relies on efficient cerebral blood flow (CBF) to wash away harmful waste products for disposal and supply the brain with an adequate supply of oxygen and sufficient nutrients.

Tesla to slash prices of solar panels in attempt to revive sales
Posted by Tracy R. Atkins in categories: business, sustainability
Some very good news.
Tesla plans to sell its solar panels at a price that’s 38 percent lower than the national average in an attempt to halt the decline of its solar business. The New York Times notes that the head of Tesla’s solar department, Sanjay Shah, wants to sell panels for between $1.75 and $1.99 a watt, compared to the national average of $2.85.

Asteroid Mining: Getting the first mission off the ground
Posted by Klaus Baldauf in categories: business, engineering, space travel
A fully-contained near-Earth asteroid retrieved to cislunar space can be used as a Research and Development destination for resource extraction and engineering tests as space-native material, unaltered by a radical change in environment, in industrial quantity, and in an accessible orbit.
As a geologist and data manager working in petroleum exploration, I’m not qualified to analyze an all-encompassing view of asteroid mining…but maybe I’m qualified to share what I see from my perspective. Rather than looking at all the reasons why asteroid mining is not currently happening, I’d like to dive deep into how changing decision-making perspectives may make a mission possible.

Why Space Aliens Might Message Us With Encoded DNA
Posted by Bruce Dorminey in category: alien life
It sounds like bad science fiction, but there are good reasons to think that E.T. may be trying to communicate with us via encoded bacterial DNA.

How Big Tech is struggling with the ethics of AI
Posted by Derick Lee in categories: ethics, military, robotics/AI, surveillance
The companies that are leading research into AI in the US and China, including Google, Amazon, Microsoft, Baidu, SenseTime and Tencent, have taken very different approaches to AI and whether to develop technology that can ultimately be used for military and surveillance purposes.
Companies criticised for overruling and even dissolving ethics boards.

Drones might be a favorite toy among adults with significant disposable income, but they’ve also proven to be incredibly useful as tools, and sometimes life-saving ones at that. The latest example of this growing trend comes to us from the University of Maryland Medical Center, where a medical drone delivered a kidney that was subsequently successfully transplanted into a patient.
The delivery, which was documented in a brief YouTube video published by UMMC, is just a small first step in a larger effort to enhance the delivery systems used for vital items like organs and other medical materials.
