As a new study determined a link between depression and cognitive decline, a separate study has suggested there may be a way to determine suicide risk from a blood test.

Doctors at Johns Hopkins University found that DNA could play a key role in determining someone's risk of suicide. The study, published in The American Journal of Psychiatry, found that the gene SKA2, which is involved in stress reaction, could predict suicide risk. The researchers conducted three experiments on brain samples from the deceased, and they conducted another three experiments using blood.

The Johns Hopkins team has previously studied postpartum depression risk factors, which they found were related to the body's level of the stress hormone cortisol. The new study found that people with less SKA2 had higher cortisol levels. In the study, researchers found that the brains of those who had died from suicide had less SKA2 than the brains of those who had died from other causes.

The researchers were then able to predict suicide risk with "80 to 90 percent accuracy based on the severity of the risk," The Daily Beast reports. The doctors are now planning to test new samples from military soldiers.

"If we can identify who is at risk, we may be able to intervene in effective ways," Dr. Zachary Kaminsky, lead author of the study, told The Daily Beast. "Notably, we could identify individuals in military populations who are more vulnerable to stress. We know they're going to be experiencing stress when they go off to combat." Meghan DeMaria

Ancient artifacts
8:17 a.m. ET

In the very last hour of the final day of a dig, archaeologists made a big discovery when a stone suddenly vanished into an underground blackhole. While excavating an area ahead of the construction of a new school in Jerusalem, the researchers had stumbled upon a Second Temple-era ritual bath, accessible by a stone staircase and an outer room complete with benches. Haaretz notes that while the discovery of ritual baths from the Second Temple-era are "not rare in the Holy Land," there is something particularly special about this discovery: It bears writing and symbols, done in mud and soot, that somehow managed to be preserved throughout the centuries.

The images on the bath's plaster walls include a boat, palm trees, various plants, and what may be a menorah. The inscriptions in ancient Aramaic and cursive Hebrew script may denote names. "The symbols we see are familiar to us from coins, sarcophagi, and graves, but a concentration like this is certainly unusual," Amit Re'em, a manager for the Israeli Antiquities Authority, told Haaretz. "It is possible that writing on mikveh walls was common, but not usually preserved."

However, to archaeologists' horror, the writing's long tenure of preservation seemed to come to an end shortly after the discovery was made. Exposed to air, the writing quickly began to fade, prompting emergency archaeology teams to rush to the scene. But it was too late to preserve the writing's legibility. At this point, archaeologists remain unsure as to who carved the writings and images, and what the message in the writing is.

Iran and the bomb

President Obama is dipping into his past political successes to promote his biggest pending diplomatic accomplishment. In a speech Wednesday at American University, Obama will argue that the same people who supported the now-unpopular invasion of Iraq in 2003 are trying hardest to sink the nuclear deal between Iran and six world powers, including the U.S. Obama's early opposition to the Iraq War helped propel him to the White House.

Obama is framing the looming vote in Congress on the nuclear deal as the most consequential foreign policy decision since the Iraq War, but he will also draw parallels between the Iran pact and nuclear treaties Presidents John F. Kennedy and Ronald Reagan negotiated and signed with the Soviet Union.

The speech is the public face of a big push to shore up support among congressional Democrats, in the face of near-unanimous Republican opposition a $40 million campaign to sink the deal led by the American Israel Public Affairs Committee (AIPAC). Three on-the-fence Democrats — Sens. Barbara Boxer (Calif.), Tim Kaine (Va.), and Ben Nelson (Fla.) — formally backed the Iran pact this week, while three others — Reps. Steve Israel (N.Y.), Nita Lowey (N.Y.), and Ted Deutch (Fla.) announced their opposition.

Sen. Tom Carper (D-Del.), who is leaning toward supporting the accord, tells USA Today that Obama's lobbying is "appropriate and needed.... God knows there are plenty of people pushing on the other side who have never read the agreement, don’t understand the agreement, who are pushing very hard to make sure it’s deep-sixed." Obama needs enough Democrats to sustain a potential veto. Peter Weber

Train Trouble
6:46 a.m. ET

Right before midnight on Tuesday, two passenger trains in India's Madhya Pradesh state derailed at a crossing near the flooded Machak River, killing at least 29 and injuring 70 more. Officials said Wednesday that up to 600 people were on the two trains, which did not collide, and at least 300 people have been rescued from the wreckage. Indian rail officials blamed the accident on monsoon rains, which they say washed away soil from under the tracks, sinking a section into the muddy ground.

In a tweet, Prime Minister Narendra Modi called the accidents "deeply distressing," and his government said the families of the deceased would each receive 200,000 rupees, or about $3,100. You can see scenes from the accident in the Associated Press video below. Peter Weber

The Daily Showdown
5:26 a.m. ET

On Monday night, 14 Republican presidential candidates gathered together on a New Hampshire stage for their first debate. On Tuesday's Daily Show, almost retired Jon Stewart barely had time to mock them. (Don't worry, he set aside a few minutes, with Sen. Ted Cruz getting the brunt.) "I shouldn't complain about the Republican race being such a circus," Stewart said. "At least it's fun to watch. The Democratic primary is basically one joyless Bataan death march to a Hillary Clinton nomination."

And then the rumor that Vice President Joe Biden is thinking of entering the Democratic race — and pundits touting Biden's proclivity for gaffes as a political plus. "Really?" Stewart asked, skepticism mixing with glee. "So the reason loose-lips McGee f—ed up his 2008 presidential run is now the reason he's a viable candidate? You know, not just blurting shit out, that's a pre-Trump presidential quality. Post-Trump, it's all about saying the crazy." Hasan Minhaj got in on the fun, "reporting" from "Clinton campaign headquarters" that Clinton is furiously engaging in "gaffe prep" to fend off the Biden challenge.

One of the best parts of The Onion, and a staple of news satire, is the point/counterpoint format. In Wednesday's New York Times, op-ed contributor Goodwell Nzou provides a real-life counterpoint to the prevailing U.S. outrage of the killing of Cecil, the Zimbabwean lion allegedly killed by a Minneapolis dentist.

When he read about Cecil's demise, "the village boy inside me instinctively cheered: One lion fewer to menace families like mine," writes Nzou, who is working toward a PhD in molecular and cellular biosciences at Wake Forest. And when he found out that the dentist is being treated as the villain, "I faced the starkest cultural contradiction I'd experienced during my five years studying in the United States." He continues:

Did all those Americans signing petitions understand that lions actually kill people? That all the talk about Cecil being "beloved" or a "local favorite" was media hype? Did Jimmy Kimmel choke up because Cecil was murdered or because he confused him with Simba from The Lion King? In my village in Zimbabwe, surrounded by wildlife conservation areas, no lion has ever been beloved, or granted an affectionate nickname. They are objects of terror. [Nzou, New York Times]

Nzou goes on to wonder why "Americans care more about African animals than about African people," then puts Cecil's death in a bit of context: "Americans who can't find Zimbabwe on a map are applauding the nation's demand for the extradition of the dentist, unaware that a baby elephant was reportedly slaughtered for our president's most recent birthday banquet." Read the entire op-ed at The New York Times. Peter Weber

The Daily Showdown
4:04 a.m. ET

The Daily Show is probably best known for Jon Stewart skewering conservatives, cable news, and Arby's, but some of its greatest segments don't have Stewart in them at all. Over the years, Daily Show correspondents have delivered field pieces from as far away as India and as close as midtown Manhattan, and some of the most memorable interviews involve people saying really crazy things on camera. The most-asked question of Stewart in his recent sadistic Q&A, he said on Tuesday's show, is "are the people in the field pieces real?"

Senior Correspondent Correspondent Jessica Williams came on to answer that: "They are real, and they do know who we are, and they don't care because we bring a camera with us.... Jon, it's like Girls Gone Wild, except they flash us their controversial ideas." To prove her point, Williams went and re-interviewed two previous subjects who, as she said, are "still returning our calls." One man, gun rights advocate Noel Flasterstein, said enthusiastically that he still likes to watch his interview with friends, and the doubling-down by Harlem pastor James David Manning — with a new, unpalatable flavor of crazy thrown in — has to be seen to believed.

"Somebody's lying," said Larry Wilmore on Tuesday's Nightly Show, in a segment dedicated to the effort to strip Planned Parenthood of all federal funding. The most recent Republican attempt to defund the women's health organization was spurred by videos showing Planned Parenthood officials discussing how they deal with tissue from aborted fetuses — Planned Parenthood says it makes no profit from donating the tissue for research, while the group that secretly filmed and edited the videos says the officials are admitting they do sell the tissue.

In context, Wilmore said, it seems clear that the Center for Medical Progress is the one lying, and "context really matters when it comes to Planned Parenthood videos, just like context matters for that text you sent last night." There's no context allowed on Fox News or in GOP talking points, so "that's why I'm calling this Planned Parenthood attack for what it really is: It's a pap smear campaign," he said. "That's exactly what it is. And in a pap smear campaign, people don't care about facts." The segment ends with an absurdist enactment of what it would look like if the GOP succeeds in its ongoing effort, and you can watch it all below. Peter Weber
