Plant Seeds Do Something Incredible When the Sound of Rain Strikes

6 days 20 hours ago
"Plant seeds can sense the vibrations generated by falling raindrops," reports ScienceAlert, "and respond by waking from their state of dormancy to welcome the water, new research shows.... to germinate in 'anticipation' of the coming deluge." The finding, discovered by MIT mechanical engineers Nicholas Makris and Cadine Navarro, offers the first direct evidence that seeds and seedlings can sense and respond to sounds in nature... "The energy of the rain sound is enough to accelerate a seed's growth," [explains Markis]. Plants don't have the same aural equipment we do to actually hear sounds, of course. But the study suggests that seeds respond to the same vibrations that can produce a sound experience in our human ears. Across a series of experiments, the researchers submerged nearly 8,000 rice seeds in shallow tubs of water, at a depth of around 3 centimeters (1 inch), and exposed some of them to falling water drops over periods of six days... A hydrophone recorded the acoustic vibrations produced by the drops, confirming that the experiment mimicked the vibrations produced by actual raindrops falling in nature — such as the driving downpours that can sometimes pelt Massachusetts' puddles, ponds, and wetlands... In their study, the researchers observed that seeds exposed to the falling drops germinated up to around 37% faster, compared with seeds that did not receive the simulated rainstorm treatment but were housed in otherwise identical conditions.

Cisco Releases Open-Source 'DNA Test for AI Models'

6 days 21 hours ago
Cisco has released an open-source tool "to trace the origins of AI models," reports SC World, "and compare model similarities for great visibility into the AI supply chain." [Cisco's Model Provenance Kit] is a Python toolkit and command-line interface (CLI) that looks at signals such as metadata and weights to create a "fingerprint" for AI models that can then be compared to other model fingerprints to determine potential shared origins. "Think of Model Provenance Kit as a DNA test for AI models," Cisco researchers wrote. "[...] Much like a DNA test reveals biological origins, the Model Provenance Kit examines both metadata and the actual learned parameters of a model (like a unique genome that comprises a model), to assess whether models share a common origin and identify signs of modification." The tool aims to address gaps in visibility into the AI model supply chain. For example, many organizations utilize open-source models from repositories like HuggingFace, where models could potentially be uploaded with incomplete or deceptive documentation. The Model Provenance Kit provides a way for organizations to verify claims about a model's origins, such as claims that a model is trained from scratch, when in reality it may be copied from another model, Cisco said. This may put organizations at risk of using models with unknown biases, vulnerabilities or manipulations and make it more difficult to resolve any incidents that arise from these risks.

Social Media Sites Got Information from Ad Trackers on US State Health Insurance Sites

6 days 22 hours ago
All 20 of America's state-run healthcare marketplace sites "include advertising trackers that share information with Big Tech companies," reports Gizmodo, citing a report from Bloomberg: Per the report, seven million Americans bought their health insurance through state exchanges in 2026, and many of them may have had personal information shared with companies, including Meta, TikTok, Snap, Google, Nextdoor, and LinkedIn, among others. Some of the data collected and shared with those companies included ZIP codes, a person's sex and citizenship status, and race. In addition to potentially sensitive biographical details about a person, the trackers also may reveal additional details about their life based on the sites they visit. For instance, Bloomberg found trackers on Medicaid-related web pages in Rhode Island, which could reveal information about a person's financial status and need for assistance. In Maryland, a Spanish-language page titled "Good News for Noncitizen Pregnant Marylanders" and a page designed to help DACA recipients navigate their healthcare options were found to be transmitting data to Big Tech firms... Per Bloomberg, several states have already removed some trackers from their exchange websites following the report. Thanks to Slashdot reader JoeyRox for sharing the news.
