Scientists Steer Infrared Light Through an “Invisible” Waveguide

VTBC ┋
Image
The discovery could advance integrated photonics, on-chip optical signal transmission, and future quantum technologies. A nanoscale gold antenna placed on a crystal can send infrared light along one narrow route, even though no physical waveguide has been carved into the material. Researchers at the 4th Physics Institute of the University of Stuttgart and the Istituto [...] Explore the content: http://dlvr.it/TV1dXJ

When companies get specific about AI, revenue growth looks different

VTBC ┋
Image
Companies that provide specific evidence of how they use AI tend to record stronger revenue growth. Researchers at Carnegie Mellon University and Larridin examined a study universe of 564 companies across 12 industry sectors. Individual analyses used smaller samples depending on data availability. The data included 478 corporate 10-K filings, more than 30,000 classified job postings, financial information, market data, and the AI Transformation Tracker built by Larridin. The tracker assigns companies scores from 1 … More → The post When companies get specific about AI, revenue growth looks different appeared first on Help Net Security.

Childhood Pesticide Exposure May Shift the Timing of Puberty

VTBC ┋
Image
Pesticide exposure during childhood may quietly shift one of puberty’s most important milestones. Researchers in Spain found that exposure to two common pesticide-related compounds was associated with changes in the timing of menstruation. One was linked to an earlier first period, while the other was connected to a later one. The findings suggest that chemicals [...] Explore the content: http://dlvr.it/TV2SKL

New $60 Blood Test Detects Lung Cancer Without Costly DNA Sequencing

VTBC ┋
Image
A simple blood test that detects chemical changes in DNA identified more than 90% of stage 2-4 lung cancers in an early study, without relying on costly DNA sequencing. Researchers at Tel Aviv University and collaborating medical centers have developed a blood test for lung cancer that analyzes chemical patterns on fragments of DNA circulating [...] Explore the content: http://dlvr.it/TV2DQW

520-Million-Year-Old Fossil Reveals How Cephalopods Learned To Float

VTBC ┋
Image
A 520-million-year-old fossil reveals an early stage in the evolution of cephalopod buoyancy. A tiny tube running through a shell helped early cephalopods control whether they rose or sank in the ocean. Living and extinct members of this group, including octopuses, squids, ammonites, cuttlefish, and nautiluses, have all faced the same challenge of regulating buoyancy, [...] Explore the content: http://dlvr.it/TV1MXS
