How Cells Use Memories of Past Inflammation To Respond to New Threats

Rockefeller University
Excerpt:
When a tissue experiences inflammation, its cells remember. Pinning proteins to its genetic material at the height of inflammation, the cells bookmark where they left off in their last tussle. Next exposure, inflammatory memory kicks in. The cells draw from prior experience to respond more efficiently, even to threats that they have not encountered before. Skin heals a wound faster if it was previously exposed to an irritant, such as a toxin or pathogen; immune cells can attack new viruses after a vaccine has taught them to recognize just one virus.
Now, a new study in Cell Stem Cell describes the mechanism behind inflammatory memory, also commonly referred to as trained immunity, and suggests that the phenomenon may be universal across diverse cell types.
“This is happening in natural killer cells, T cells, dendritic cells from human skin, and epidermal stem cells in mice,” says Samantha B. Larsen, a former graduate student in the laboratory of Elaine Fuchs at The Rockefeller University. “The similarities in mechanism are striking, and may explain the remitting and relapsing nature of chronic inflammatory disorders in humans.”

Excerpt:
When Facebook said Tuesday that it was suspending the accounts of a team of NYU researchers, it made it seem like the company’s hands were tied. The team had been crowdsourcing data on political ad targeting via a browser extension, something Facebook had repeatedly warned them was not allowed.
“For months, we’ve attempted to work with New York University to provide three of their researchers the precise access they’ve asked for in a privacy-protected way,” wrote Mike Clark,…

‘Law’ that defined how chips have been made for decades has run itself into a cul de sac
From www.theregister.com

Excerpt:
In 1975, eight years after leaving Fairchild to co-found Intel, Moore revised his “law”, actually just an observation, to a doubling every two years. But the other predictions in his original paper of revolutions in computing, communication and general electronics had taken hold. The chip industry had the perfect metric to aim for a rolling, virtuous milestone like no other.
Since then, according to Professor Erica Fuchs of Carnegie Mellon University, “half of economic growth in the US and worldwide has also been attributed to this trend and the innovations it enabled throughout the economy.” Virtually all of industry, science, medicine, and every aspect of daily life now depends on computers that are ever faster, cheaper, and more widely spread…..
….during the three-node transition from 65nm through 40nm to 28nm, cost per wafer went up by only a third from $2k to $3k while per-chip dropped by two-thirds from $1,428 to $453. Those days have gone, and are not coming back.
Even if there are two or three more cycles left through transistors, packaging and architectural changes, the drivers that Gordon Moore saw for silicon have been replaced by force of habit. What alternatives are there?
