JD Vance and Marco Rubio's Senate successors are cruising to the primaries. Artificial intelligence is fueling job cuts and anxiety in the tech world. And a new genetic test may predict a child's risk of obesity in adulthood. Here's what to know today.
Vance and Rubio's Senate successors avoid GOP primary drama
As JD Vance and Marco Rubio shot to the top of Donald Trump's list of possible running mates last year, a hint of dread set in for Republicans in Ohio and Florida.
If either of the then-senators were to leave for the White House, their governors would need to appoint a successor — a potentially messy scenario in states where the Republican Party is filled with rivalrous internal factions.
In the end, both Vance and Rubio joined the new Trump administration. And their appointed successors, Jon Husted in Ohio and Ashley Moody in Florida, are facing smoother than expected paths, at least for now.

Neither Husted nor Moody has a credible primary opponent at the moment. Husted scored an early Trump endorsement, while Moody has made efforts to get closer to the president's political team.
Both are also coming off strong fundraising quarters that could scare away any Republican tempted to challenge them.
Given recent trends in both states, Husted and Moody will enter their 2026 special elections as favorites in November, too.
The president's backing helped Husted secure early endorsements, and his decades-long record in elected office makes him one of the best-known politicians in the state. Combining these factors helps him 'clear the field,' one campaign manager said.
Since her appointment to the Senate in January, Moody has enhanced her ties to Trump while strengthening her financial footing, ending June with $2.2 million cash on hand. Any primary opponent would 'quickly find their candidacy crushed,' a GOP veteran said.

AI is fueling job cuts, but is it really more efficient?
As news swirls about multibillion-dollar deals for artificial intelligence startups, a small research nonprofit group is turning some heads in the tech world.
Its findings were simple but surprising: AI made software engineers slower.
'When developers are allowed to use AI tools, they take 19% longer to complete issues,' the nonprofit group, METR, which specializes in evaluating AI models, said in its report.
The results offer a reality check for major companies like Google and Microsoft moving toward AI generated coding.
Overall job openings for software developers hit a five-year low earlier this year, and many coders are anxious about AI's responsibility for the slowdown. While it's clear AI can write code, it's far less certain whether the technology is a direct threat to coding jobs in the short term.
'We have tools that are way more powerful than any we've seen before,' one expert said, 'But there's also a long way to go.' Read the full story here.
New genetic test could predict adult obesity risk
A new genetic test may predict a child's risk of obesity in adulthood, paving the way for early interventions.
In a study published in the journal Nature Medicine, scientists examined the genes of more than 5 million people to determine which genetic variants are linked to obesity. Certain variants can affect how a person's body stores fat or make them more prone to overeating.
With this information, the researchers were able to create a score that could be used to predict a person's risk of obesity as an adult — before they even turn 5.
Identifying a person's genetic risk in childhood and intervening with lifestyle coaching could make a big difference in adult obesity rates, said study co-author Ruth Loos.
Loos' test is twice as effective as the method doctors currently use, but was primarily focused on people with European ancestry. Here's what else we know.

Staff Pick: Meet the weather detectives trying to better understand hail
Hail is a sneaky threat that costs the U.S. tens of billions of dollars in damage each year. NBC News meteorologist and climate reporter Chase Cain visited Montana to catch up with researchers who drive into storms — come hail or high water — hoping to crack open the science of how hail forms and how to better forecast when big hail will strike.
The project, appropriately called ICECHIP, is the first major field campaign studying hail in nearly 50 years. Researchers raced across the plains to capture the inner dynamics of dozens of storms with tools like mobile radar and drones with the goal of testing whether climate change is increasing powerful updrafts inside thunderstorms, which can help form larger hailstones. Think of it like 'Twister' but for hail.
