Nancy Guthrie missing: Forensic scientist encourages new investigative approach since case ‘isn’t cold yet’

TUCSON, Ariz. — One criminal expert said even though the investigation into Nancy Guthrie “isn’t cold yet,” the “best” forensic scientists should go into her house and “scrutinize” everything inside.

Forensic scientist Peter Valentin made the comments Friday on Fox News’ “Crime and Justice” podcast with Donna Rotunno while discussing Nancy Guthrie’s disappearance. Investigators continue to search for Nancy Guthrie as she has been missing for more than three weeks. Guthrie was forcibly taken from her Tucson, Arizona, home in the early morning hours of Feb. 1, Pima County Sheriff Chris Nanos previously said.

Fox News Digital previously reported that some DNA found in Nancy Guthrie’s home came back to individuals with a reason to be there, two federal law enforcement sources said. DNA from a suspicious glove recovered two miles from Nancy Guthrie’s home was also tested, but didn’t match any of the samples from inside the home or any known criminals in the FBI’s CODIS database.

Valentin, who’s chair of the Forensic Science Department at the University of New Haven’s Henry C. Lee College of Criminal Justice and Forensic Sciences, said on the “Crime and Justice” podcast that a fresh set of eyes might be needed.

“What I would suggest is that you go into that house with the best people in each discipline in forensics,” Valentin said. “Go into that house and scrutinize that house, looking for the trace evidence that must exist, or hopefully still exists.”

The forensic expert is very confident that there is some type of evidence left behind by whatever individual is suspected to have taken Nancy Guthrie from her home.

“Because if people went into that home, and we believe they did, right? To take her from that house, there must be evidence of their presence in that home. Where is it? What is that evidence? We need to find it,” he said.

He also cautioned that the key piece of evidence that breaks the case might not be “obvious.”

“It’s not going be the obvious DNA profile somewhere, it is not going to be the obvious latent fingerprint. It’s probably some of the things that we’ve probably not used as much, right? The hair, the fibers, the other kinds of trace evidence. But we’ve got to start cobbling together all the forensic evidence we have at our disposal to move this case forward, because otherwise it might not move forward,” Valentin said.

Investigators got a fresh lead on Thursday when Fox News Digital exclusively reported that a resident in the Catalina Foothills neighborhood, about 2.5 miles from where Nancy Guthrie lives, has a Ring camera that captured 12 cars passing by on the morning of her suspected abduction. Some of the activity took place around 2:30 a.m., when authorities say the 84-year-old Guthrie’s pacemaker device last synced with her iPhone.

In a new Instagram story posted on Friday, Savannah Guthrie pleaded with people to send in tips, and to “be the one who brings her home,” referring to her mother, Nancy Guthrie.

New York halts robotaxi expansion plan

0


NEWYou can now listen to Fox News articles!

New York just hit pause on expanding robotaxis beyond New York City. 

Gov. Kathy Hochul has withdrawn her proposal that would have allowed commercial robotaxi services in smaller cities across the state. That means places outside New York City will not see driverless ride services anytime soon.

If you live in Buffalo, Rochester or Albany, that future just got pushed further down the road. Meanwhile, one major player still plans to move forward inside the city.

New York has paused plans to expand robotaxi service beyond New York City, slowing statewide deployment.  (AP Photo/Terry Chea, File)

Waymo moves forward despite New York robotaxi expansion pause

Waymo, the self-driving arm of Alphabet, received its first permit last year to test autonomous vehicles in New York City. However, the permit requires a trained specialist behind the wheel. That testing permit remains in place. So while statewide expansion is off the table for now, Waymo’s New York City testing program continues. The company already offers paid driverless rides in parts of:

  • The San Francisco Bay Area
  • Los Angeles
  • Phoenix
  • Austin
  • Atlanta

According to company data and state regulators in Arizona and California, Waymo has logged millions of fully autonomous miles. Arizona transportation officials have reported lower crash rates per mile compared with human drivers in certain operational zones. California’s DMV and Public Utilities Commission continue to monitor safety performance and incident reporting.

The company says it hears from thousands of New Yorkers who have ridden in Waymo vehicles elsewhere and want the service at home. Still, expanding beyond the city now faces a political roadblock.

UBER UNVEILS A NEW ROBOTAXI WITH NO DRIVER BEHIND THE WHEEL

Why Hochul pulled the New York robotaxi expansion plan

The governor’s office said support was not there in the state Legislature after conversations with stakeholders. That language matters. Self-driving vehicle rules involve state lawmakers, labor groups, local officials, safety advocates and insurance regulators. Expanding robotaxi services into smaller cities likely raised concerns about:

  • Safety oversight
  • Liability rules
  • Local job impact
  • Emergency response coordination

Autonomous vehicle deployment remains under intense scrutiny nationwide. After a high-profile incident involving Cruise in San Francisco in 2023, regulators tightened oversight. Cruise later suspended operations, and General Motors scaled back its robotaxi ambitions. Waymo has not recorded a similar major injury event in public reporting. That distinction has helped it expand in states like Arizona and Texas. Even so, public trust remains fragile.

What this means for you

You might be thinking, “I do not live in New York. Why should I care?” Because state decisions like this often ripple outward. If New York, one of the largest transportation markets in the country, slows expansion outside its biggest city, other states may take note. Lawmakers across the country watch how New York handles new technology.

Here is what this pause signals:

Robotaxi rollouts will stay uneven

Some cities will embrace them quickly. Others will wait for more data and clearer rules.

Politics matter as much as technology

Even if autonomous vehicles prove safer per mile in controlled settings, public policy decides where they operate.

Your city could be next in line

As companies push for expansion in major metros, debates over safety, job liability and infrastructure will follow. If you rely on ride-hailing services, autonomous vehicles could eventually lower costs and increase availability. On the other hand, local drivers and labor groups may push back hard. This tension will play out city by city.

The bigger national picture for robotaxi expansion

Federal agencies like the National Highway Traffic Safety Administration continue to collect crash data and investigate autonomous vehicle performance. However, states control many of the rules governing commercial operations. That means America may not get one unified robotaxi system. Instead, it may look like a patchwork. Phoenix might move fast. Austin might expand aggressively. Buffalo might wait.

In the meantime, companies like Waymo continue refining software using real-world miles and sensor data. The more data they collect, the stronger their safety case becomes. Yet public perception often hinges on a single viral incident. Technology evolves quickly. Regulation moves more slowly.

Kurt’s key takeaways

New York’s decision is not a death blow to robotaxis. It is a reminder that innovation must pass a political test. Waymo still plans to move forward in New York City. Smaller cities across the state will wait. Other states will watch. The question is no longer whether autonomous vehicles will expand. It is how fast and where.

If driverless cars reduce crashes and improve pedestrian safety, should lawmakers speed up approval? Or should they move cautiously and protect existing systems until every risk is understood? What would you want your city to do? Let us know by writing to us at Cyberguy.com.

Common nighttime noise exposure may trigger heart problems, study suggests

0


NEWYou can now listen to Fox News articles!

Living near heavy traffic could negatively impact your heart health.

A European study, published in the journal Environmental Research, found that exposure to nighttime road traffic noise is linked to changes in the blood, leading to worsened cholesterol and cardiovascular risks.

The researchers considered data from the U.K. Biobank, Rotterdam Study, and Northern Finland Birth Cohort 1966, including more than 272,000 adults over the age of 30, according to a press release.

Nighttime road noise exposure was estimated at all participants’ homes based on national noise maps. Researchers also took blood samples to measure the participants’ metabolic biomarkers for disease, then mapped the link between nightly noise levels and existence of biomarkers.

Exposure to loud noise was associated with increased concentrations of cholesterol-related biomarkers. (iStock)

The study found that people exposed to louder noise at night — especially sounds above 55 decibels — showed changes in 48 different substances in their blood. Twenty of these associations “remained robust” throughout all cohorts.

Exposure to loud noise was associated with increased concentrations of cholesterol-related biomarkers, especially LDL “bad” cholesterol, IDL (intermediate-density lipoprotein) and unsaturated fatty acids.

NEARLY 90% OF AMERICANS AT RISK OF SILENT DISEASE — HERE’S WHAT TO KNOW

As noise levels increased, starting at around 50 decibels, cholesterol markers rose steadily, the release stated.

The authors concluded that this study “provides evidence that nighttime road traffic noise exposure from 50 dB upward is associated with alterations in blood cholesterol and lipid profiles in adults.”

Study co-author Yiyan He, doctoral researcher at the University of Oulu in Finland, noted that in this type of research, small effect sizes are expected, and environmental exposures such as traffic noise are “typically modest.”

“Despite this, we observed statistically robust and consistent associations across many biomarkers, especially those related to LDL and IDL lipoproteins,” she told Fox News Digital.

“We also identified a clear exposure-response pattern starting at around 50 dB, suggesting that metabolic changes become more evident as noise levels increase.”

This aligns with public health guidance, as the World Health Organization recommends lower nighttime noise limits at around 40 to 45 dB, Yiyan He added.

“This finding may clarify the association between traffic noise and cardiometabolic diseases,” the researchers wrote. (iStock)

“The 55 dB level is often used as an interim benchmark associated with substantial noise annoyance and sleep disturbance,” she said. “In our study, we observed associations not only at 55 dB, but also indications of effects emerging at around 50 dB.”

The strength and consistency of the cholesterol-related associations were surprising, as these changes are usually “subtle.”

“Instead, we found consistent associations across multiple large European cohorts, which strengthens confidence that the findings may reflect real biological patterns,” Yiyan He went on. “We were also interested to see that effects were minimal below ~50 dB, suggesting a possible threshold-like pattern.”

HEART DISEASE THREAT PROJECTED TO CLIMB SHARPLY FOR KEY DEMOGRAPHIC

The researcher noted that these findings were consistent across genders, education levels and obesity status.

The study was restricted to White Europeans, which posed a limitation. There was also a lack of information on the fasting status in the UK Biobank.

Changes in cholesterol levels were more severe than researchers expected. (iStock)

“Fasting can influence levels of certain metabolites, particularly fatty acids,” Yiyan He said. “However, based on UK Biobank documentation, fewer than 10% of participants were fasting for at least eight hours, and our main findings focused on cholesterol-related biomarkers, which are generally less sensitive to short-term fasting.”

The researchers also lacked information on bedroom location, indoor noise exposure and time spent at home.

“These factors may introduce non-differential exposure misclassification,” Yiyan He said. “Additionally, noise exposure estimates were based on participants’ temporary residential addresses at the time of blood sampling, without considering the duration of residence.”

“Many of these limitations would tend to bias results toward the null, so the consistent associations we observed remain noteworthy.”

Experts recommend taking measures to limit traffic noise at night. (iStock)

Based on this latest research, Yiyan He noted that nighttime noise is a “health-relevant exposure,” not just “an annoyance.”

“Our findings suggest that nighttime traffic noise may subtly but consistently affect metabolic health,” she said. “While the changes in cholesterol and lipid levels for any one individual are small, traffic noise affects a very large number of people, which means the potential public health impact could be substantial.”

TEST YOURSELF WITH OUR LATEST LIFESTYLE QUIZ

The researcher recommends taking measures like improving sound insulation, using noise-reducing strategies and placing bedrooms on the quieter side of the home when possible.

“Because sleep is a key pathway linking noise to health, protecting the nighttime sleep environment is especially important,” she added.

Amazon commits $50 billion to OpenAI; announces multi-year partnership with AWS

0



Amazon will invest $50 billion in OpenAI, starting with an initial $15 billion and followed by an additional $35 billion tied to certain conditions. This comes as OpenAI closed its massive $110 billion funding round, reportedly at a pre-money valuation of $730 billion.

Amazon’s investment is the highest among its peers in this round, as Nvidia and SoftBank have promised to invest $30 billion each in this round.

“OpenAI… is an extremely talented team with great products, IP, and vision for how they can continue to serve customers and enterprises. We think they’ll be one of the big winners in AI, we can help them grow, and we believe we’ll earn a strong return for Amazon over the long term,” said Amazon CEO Andy Jassy in a post on X.

Amazon has entered into a multi-year and multi-fold partnership with OpenAI alongside its investment. This would entail a joint development of a Stateful Runtime Environment (SRE) powered by OpenAI’s models, which will be made available through Amazon Bedrock. Designed for enterprise use, an SRE is an environment that allows artificial intelligence (AI) systems to retain context, access compute and memory, integrate across software tools and data sources, and manage ongoing workflows. Amazon Bedrock is a service by Amazon Web Services (AWS) that enables building and scaling generative AI (GenAI) applications.“Combining OpenAI’s intelligence with Amazon’s infrastructure and global reach helps us put powerful AI into the hands of businesses and users at real scale,” said OpenAI CEO and cofounder Sam Altman.

AWS will also become the exclusive third-party cloud distribution provider for OpenAI Frontier, the company’s advanced enterprise AI platform. Frontier allows enterprises to build, deploy, and manage teams of AI agents that function across real business systems with shared context, built-in governance, and enterprise-grade security.

The two companies are further expanding their existing cloud agreement by $100 billion over eight years. OpenAI will commit to consuming approximately 2 gigawatts (GW) of AWS Trainium compute capacity, including future Trainium3 and Trainium4 chips. This long-term arrangement is designed to lower costs, improve efficiency, and secure large-scale compute capacity to support advanced AI workloads such as SRE and Frontier. Training is specialised, high-performance computing resource of AWS, which is designed to accelerate the training and fine-tuning of large language models (LLMs) and generative AI.

Finally, the two companies will also collaborate on developing customised models tailored for Amazon’s customer-facing applications, complementing Amazon’s existing AI offerings, including its Nova model family.

120 Bahadur Box Office: Shows some growth on Saturday :Bollywood Box Office – Bollywood Hungama

0


With 120 Bahadur getting some good reviews coming its way, one waited to see if word-of-mouth will catch up and the collections will double up on Saturday. That didn’t quite turn out to be the case though as from Rs. 2 crores that were collected on Friday, the film moved to Rs. 3.25 crores on Saturday. Though growth is there, bigger jump was the need of the hour.

120 Bahadur Box Office: Shows some growth on Saturday

The Farhan Akhtar starrer is primarily for the major multiplexes at key urban centres and its doing well in pockets. However, the budget of the film warranted that it does well across board, at least, in all the multiplexes of A centres. This is what had helped Bhaag Milkha Bhaag emerge as a Rs. 100 Crore Club superhit and that film had got some support from B centres as well. However, 120 Bahadur has arrived at a time when it’s increasingly difficult to get audiences to theatres and that’s showing in the collections so far.

Two days’ numbers for the film are Rs. 5.25 crores and had this been the opening day number, then it would have been far better. There is a huge journey ahead for 120 Bahadur and one now waits to see if there is some substantial growth today that could make one look forward to the footfalls during the weekdays.
