Historic paintings are being reborn with MIT's AI-based restoration method

techspot.com Skye Jacobs 2025-09-02 06:15:00

TL;DR: A new chapter in art conservation is unfolding at the Massachusetts Institute of Technology, where mechanical engineering graduate student Alex Kachkine has developed a technique that could dramatically change how damaged paintings are restored. For centuries, art restoration has been a painstaking, manual craft, with conservators spending months or even years meticulously retouching faded or cracked works, often matching colors by hand for thousands of tiny regions.

Why you should always put your phone face down on a table (hint: it's not just about being polite)

Sabrina Ortiz/ZDNET A friend of mine recently told me, "I always keep my phone on silent mode… which doesn't matter because I compulsively look at it every three minutes anyway." He's not the only one. From becoming a text addict to having full-blown smartphone dependency, the urge to look at and interact with our "flat things" has been deeply ingrained into our collective behavior for some time now.

How Prehistoric Mammoth Tusks Could Help Bust Modern-Day Ivory Smugglers

gizmodo.com Margherita Bassi 2025-09-02 04:00:57

Selling elephant ivory—a hard white material from elephant tusks, for which elephants are often killed—is illegal. Selling ivory collected from the remains of extinct Mammoths, however, is—somehow—not. Because the two are hard to tell apart, illegal traders are slipping under the radar by mixing elephant ivory with legally traded mammoth ivory. A new forensic tool, however, might soon put an end to this nefarious trick. Wildlife forensic scientists in China suggest that authorities can differen

Tharon Green/CNET Though the housing market is never immune to political and economic volatility, mortgage rates have been eerily calm. Over the last month, the average rate for a 30-year fixed mortgage has moved in a narrow range between 6.8% and 7%. An escalating war in the Middle East could spark fresh volatility across global markets, significantly affecting oil prices and the US dollar.

Interesting Bits of Postgres Grammar

news.ycombinator.com Steve Dignam 2025-09-03 07:09:21

I’ve been working on Squawk for a while, it’s a linter for PostgreSQL, and it now uses a handmade parser. So let’s explore some interesting bits from the Postgres grammar. Custom Operators Very few operators are defined in the grammar itself and lots of Postgres features rely on custom operators. For example, Postgres uses <-> for comparing geometric types, along with a whole host of others: ## , @-@ , # , @> , <@> , &< , &> , |>> , |<< , <^ , >^ , ?- , ?| , ?|| , ~= . Note: custom operator

Tech companies are hellbent on pushing out ever more advanced artificial intelligence models — but there appears to be a grim cost to that progress.
