The field is in disagreement about where it should go and why.

Despite the huge contributions of deep learning to the field of artificial intelligence, there’s something very wrong with it: It requires huge amounts of data. This is one thing that both the pioneers and critics of deep learning agree on. In fact, deep learning didn’t emerge as the leading AI technique until a few years ago because of the limited availability of useful data and the shortage of computing power to process that data.
Reducing the data-dependency of deep learning is currently among the top priorities of AI researchers.
In his keynote speech at the AAAI conference, computer scientist Yann LeCun discussed the limits of current deep learning techniques and presented the blueprint for “self-supervised learning,” his roadmap to solve deep learning’s data problem. LeCun is one of the godfathers of deep learning and the inventor of convolutional neural networks (CNN), one of the key elements that have spurred a revolution in artificial intelligence in the past decade.
Scientists have found an ancient submarine forest of bald cypress trees entombed in Mobile Bay off the coast of Alabama.
According to the National Oceanic and Atmospheric Administration (NOAA), the forest flourished on the banks of a prehistoric river near the Gulf of Mexico nearly 60,000 years ago. When the trees died, their massive trunks became entombed in peat and sediment. Eventually, sea levels rose, the coastline receded, and the remains of these ancient trees were buried by the sea. The forest was preserved, undisturbed for millennia, until recent intensifying storms along the coast began to expose it.
Earlier this week, NOAA shared a video of the incredible site (below), showing it teeming with schools of fish.
Because crises shape history, there are hundreds of thinkers who have devoted their lives to studying how they unfold. This work – what we might call the field of “crisis studies” – charts how, whenever crisis visits a given community, the fundamental reality of that community is laid bare. Who has more and who has less. Where the power lies. What people treasure and what they fear.
Times of upheaval are always times of radical change. Some believe the pandemic is a once-in-a-generation chance to remake society and build a better future. Others fear it may only make existing injustices worse. By Peter C Baker.
Broadly speaking, animals tend to be sexually dimorphic. You have males, with small gametes, and females, with large gametes, both of which are required for sexual reproduction. Every now and again, though, nature throws a curveball — producing an organism that’s a combination of both sexes, divided straight down the middle.
This condition is known as gynandromorphism, and scientists have just found the first known gynandromorphic individual of its species in a nocturnal bee native to Central and South America, Megalopta amoenae.
On its left side, the bee is physiologically male. It has a small, dainty mandible, a long antenna, and a thin, delicate hind leg with fewer bristles. The right side has female characteristics — a shorter antenna, a pronounced, toothed mandible, and a thick, hairy hind leg.
Gas Price in Venezuela at 2 Cents

One week ago…
“Gasoline in the United States has fallen to about $2 a gallon and continues to slide. However, that price is nowhere near the least expensive in the world. Venezuela has the least expensive gas in the world at two cents per gallon.”
