Silvis Materials develops biodegradable cellulose adhesives to replace petroleum glues

Silvis Materials, cofounded by MIT alum Patty Ferreira, has created adhesives made from cellulose that fully biodegrade, aiming to replace petroleum-based glues used in packaging labels, furniture joints, and construction materials. Ferreira notes that petroleum adhesives currently prevent otherwise recyclable containers from being processed because the glue holding labels on contaminates the recycling stream.

Chinese humanoid robots break sprint records, some catch fire, at Beijing games

At the second World Humanoid Robot Games in Beijing (August 22-26), robots competing in a 100-meter sprint and standing high jump beat human world records set by Usain Bolt and others, marking a jump from last year's event where they trailed human performance. Some sprinting robots couldn't stop in time, crashing into barriers, falling, and in a few cases breaking apart with sparks or catching fire, while separate tasks like hanging laundry showed robots still moving far slower than humans.

Python's stringprep module flagged for Unicode version mismatch security flaw

Security researcher Seth Larson identified that Python's stringprep module, used in IDNA 2003 domain name processing, relies on str.lower() which uses whatever Unicode version ships with the interpreter rather than the fixed Unicode 3.2 version specified in RFC 3454. This means case-folding behavior for internationalized domain names can differ across Python versions, since unicodedata.unidata_version varies by interpreter build.

Conservators at the Indianapolis Museum of Art at Newfields are researching the phosphorescent and fluorescent pigments used by late fashion designer Stephen Sprouse in his 1980s Day-Glo creations, aiming to prevent the colors from dulling with age.
