Astronomers find 'Tatooine' planet orbiting two stars
The Brief
Astronomers believe they've discovered a "Tatooine"-like planet orbiting two stars in a galaxy far, far away.
The planet is orbiting two brown dwarfs, which are also known as failed stars.
It's about 120 light years away from our solar system.
If you're a "Star Wars" fan, you might be excited to learn scientists may have discovered a planet that's orbiting two stars, much like the fictional planet of "Tatooine."

The planet is located about 120 light years away from our solar system, according to astronomers at the University of Birmingham, U.K.
A light year is nearly 6 trillion miles, in case you were trying to convert the distance.
The exoplanet appears to take an unusual path around two brown dwarf stars, circling at a right angle.
Brown dwarfs are sometimes called failed stars because they're lighter than stars but are heavier than gas giant planets.
The pair of brown dwarfs were first discovered years ago and scientists noticed that the twins eclipse each other so one is always partly blocked when seen from Earth.
In a new analysis, researchers found that the brown dwarfs' motion was changing — a quirk that's less likely to happen if they circled each other on their own. The research was published in the journal Science Advances.
The planet was discovered using the European Southern Observatory's Very Large Telescope (LVT).
Yes, there are actually several dozen planets that are orbiting two stars throughout the cosmos, scientists said.
But the new planet's odd orbit sets it apart. Though it hasn't been directly spied on, scientists say more research is needed to be sure it's out there and figure out its mass and orbit.
What they're saying
"I wouldn't bet my life that the planet exists yet," said Simon Albrecht, an astrophysicist with Aarhus University who had no role in the new study.
Probing these wacky celestial bodies can help us understand how conditions beyond our solar system may yield planets vastly different from our own, said study author Thomas Baycroft with the University of Birmingham.
Planets circling twin stars "existed in sci-fi for decades before we knew that they could even really exist in reality," he said.

Researchers issue warning after new study reveals powerful phenomenon causing flooding along coast: 'Poses threats to both lives and infrastructure'
New research indicates that a climate-change weakened network of ocean currents is a cause of a significant portion of flooding along the northeast coast of the United States. A vital ocean system, referenced by some as the Earth's "cardiovascular system," is shifting and contributing to flooding events. CNN reported that a new study, published in mid-May by Science Advances, showed that from 2005 to 2022 the U.S. Northeast experienced up to eight days of flooding annually due to sea level changes driven by a slowdown of the Atlantic Meridional Overturning Circulation. This means roughly 20% to 50% of total flooding events at monitored sites could be linked to the weakening AMOC. While extreme weather like flooding has always occurred, human activities are intensifying it. As a 2024 post from the Union of Concerned Scientists explained, human activity has caused temperatures to rise globally, melting ice sheets and dumping huge amounts of freshwater into the North Atlantic. "Because of this," according to the UCS, "the ocean waters in the north are less salty and less dense than before," upending delicately balanced circulation patterns. Less dense and warmer water takes up greater space, leading sea levels to rise along with the temperatures. This research is part of a growing body of work demonstrating how a weakening AMOC can strengthen flooding events. Higher sea levels can supercharge floods and storm surges, causing powerful waters to reach further inland. They can also make flooding more frequent by setting the baseline much closer to flood status — just as a mostly full glass of water is more likely to spill over with just a little added on top. Study co-author Liping Zhang, who is also a scientist at the National Oceanic and Atmospheric Administration, told CNN that flooding in the Northeast coastal states can "reshape the coastal environment … (and) poses threats to both lives and infrastructure in coastal regions." That could mean sudden basement floods in homes never before prone to such issues or washed-out roads delaying commutes and cutting off vital services to those in need. Public works and recreational areas could also sustain dangerous and costly destruction, threatening human health and safety too. Do you think your city has good air quality?

Such hazards could end up forcing some residents and even whole communities to relocate, with marginalized populations facing disproportionate impacts. High sea levels can also displace barrier islands and critically damage wildlife habitats. The NOAA has called for a cost-effective and enhanced observation network across the Atlantic Ocean to spot where AMOC changes originate. Meanwhile, experts at a January 2025 JPI Climate meeting agreed to complete a report covering potential tipping points, consequences, and mitigation strategies. Research like this new study can arm experts with the information they need to understand the coming dangers and plan for how to help communities counter and navigate them. In the U.S., efforts to prevent Northeast flooding are underway, including marsh restoration and flood resilience initiatives. Eco-friendly practices could help limit further disruption of the AMOC by mitigating temperature rise, and one option for homeowners is to reduce the production of heat-trapping pollution by leveraging a clean, renewable source like solar energy. Installing solar panels together with a battery system comes with added benefits, like ensuring a home's access to power in the wake of weather-related grid outages and significantly lowering energy bills. Resources like the free tool from EnergySage can also help residents compare vetted local installers, with the potential to save homeowners up to $10,000. Helping whole communities to learn about the benefits of cleaner options can multiply the effect and galvanize actions close to home with the possibility of far-reaching impacts. Organizing local walking and biking groups, for example, and supporting public transit can help cut back on planet-warming gases.

Can a Blood Test Tell if Pancreatic Cancer Therapy Works?
A new blood test that uses artificial intelligence (AI) may offer a faster, more accurate way to determine whether pancreatic cancer treatment is working. Known as ARTEMIS-DELFI, the test detects DNA fragments shed by pancreatic tumors that circulate in blood. In two large clinical trials of immunotherapy for metastatic pancreatic cancer, researchers successfully applied the test to identify patients with therapeutic responses. Two months after starting treatment, ARTEMIS-DELFI was better at predicting outcomes than imaging or other existing clinical and molecular markers. 'Early determination of response to therapy is crucial for patients with pancreatic or other cancers, especially when treated with immunotherapy where we do not have good biomarkers of response,' senior author Victor Velculescu, MD, PhD, codirector of the Cancer Genetics and Epigenetics Program at Johns Hopkins Kimmel Cancer Center in Baltimore told Medscape Medical News. 'We want to know as quickly as we can if the therapy is helping the patient or not. If it is not working, we want to be able to switch to another therapy,' Velculescu added in a news release. The study was published online in Science Advances . Real-Time Monitoring of Therapeutic Response Pancreatic cancer, one of the deadliest cancers, often goes diagnosed at an advanced stage, with limited treatment options and a dismal prognosis. Traditional methods for assessing treatment response — such as CT imaging and the CA19-9 tumor marker — are often unreliable, especially during immunotherapy, where pseudo-progression can obscure outcomes. To address this challenge, Velculescu and colleagues developed two advanced liquid biopsy techniques that leverage cell-free DNA (cfDNA) for real-time, noninvasive therapeutic monitoring — ARTEMIS-DELFI (AI-driven, tumor-independent genome-wide cfDNA fragmentation profiles and repeat landscapes) and WGMAF (tumor-informed whole-genome mutant allele fraction). Both techniques were tested in participants in the phase 2 CheckPAC trial, which evaluated nivolumab with or without ipilimumab in combination with radiation in patients with refractory metastatic pancreatic cancer. Researchers established strong correlations between cfDNA signals and patient outcomes. With WGMAF, molecular responders to treatment had significantly longer median progression-free survival (PFS: 157 days vs 51 days; hazard ratio [HR], 0.23; P = .0053) and overall survival (OS: 319 days vs 126 days; HR, 0.29; P = .011) than nonresponders. With ARTEMIS-DELFI, responders also had significantly longer PFS (105 days vs 53 days; HR, 0.28; P =.0024) and OS (233 days vs 172 days; HR, 0.12; P < .0001) when than nonresponders. The researchers validated ARTEMIS-DELFI in the PACTO trial, which assessed gemcitabine/nab-paclitaxel with or without tocilizumab for advanced pancreatic cancer. Once again, ARTEMIS-DELFI scores were significant predictors of survival ( P = .048). Both WGMAF and ARTEMIS-DELFI outperformed standard imaging and molecular markers in predicting treatment outcomes within 2 months. However, ARTEMIS-DELFI was more effective and practical, as it relies solely on DNA fragments circulating in blood. 'The 'fast-fail' ARTEMIS-DELFI approach may be particularly useful in pancreatic cancer where changing therapies quickly could be helpful in patients who do not respond to the initial therapy,' lead study author Carolyn Hruban, PhD, postdoctoral researcher at the Dana-Farber Cancer Institute in Boston, said in a news release. 'It's simpler, likely less expensive, and more broadly applicable than using tumor samples.' Limitations and Future Directions The researchers noted their analysis drew from a relatively small sample size – 40 patients each in CheckPAC and PACTO — with fewer evaluable by WGMAF due to tumor biopsy constraints. Some liquid biopsy timepoints did not align exactly with imaging assessments. As with most pancreatic cancer studies, there were few responders, limiting the pool of patients to analyze. Additionally, cut points for determining molecular response were derived from quantiles of observed responses rather than predefined thresholds. The researchers plan future prospective studies to determine whether ARTEMIS-DELFI can help clinicians more efficiently identify effective therapies and improve outcomes across various cancers. Earlier this year, the researchers reported that a variation of the cell-free fragmentation monitoring approach called DELFI-tumor fraction (DELFI-TF) was helpful in assessing colon cancer therapy response. Velculescu and colleagues have founded a company, DELFI Diagnostics, which has developed a fragmentomics monitoring test for research purposes and eventual use within clinical care. Nice Validation, More Work Ahead Commenting on this research for Medscape Medical News , Karyn A. Goodman, MD, MS, professor and vice chair of clinical research, Department of Radiation Oncology, Icahn School of Medicine at Mount Sinai, New York City, noted that 'the approach of using circulating tumor DNA to evaluate response to therapy is being evaluated for many tumor types, including pancreas cancer.' 'This study of the ARTEMIS-DELFI test is a nice validation of this approach using a different method of detecting tumor-related cfDNA that does not require a biopsy to establish the types of mutations in a particular tumor,' said Goodman, associate director of clinical research at The Tisch Cancer Institute, Icahn School of Medicine at Mount Sinai, New York City. Goodman noted that the test does not use AI to make treatment decisions but rather to help identify the features in the cfDNA that correlate with tumor burden and treatment response. 'If the ARTEMIS-DELFI test detected a lower level of tumor-related cfDNA, this correlated with a good response to therapy and appeared to be more accurate than typical imaging tests,' observed Goodman, who wasn't involved in the study. Although emphasizing that further prospective studies are needed, Goodman called the results 'very exciting,' as they point to a future with more noninvasive options for monitoring treatment response in pancreatic cancer.

Scientists Uncover DNA Puzzle: 6,000-Year-Old Remains Reveal Mysterious Ancestors
Archaeologists working in Colombia's Bogotá Altiplano recently uncovered ancient human remains that have left scientists puzzled. Genetic analysis of the 6,000-year-old skeletons revealed DNA with no direct connection to any known ancient or modern populations in South America, a finding that upends previous assumptions about regional ancestry. The team, whose study was published in Science Advances, analyzed both mitochondrial and genome-wide data from 21 ancient individuals who lived in the region between 6,000 and 500 years ago. The results show a striking lack of continuity with known Indigenous populations in Colombia. Instead, the genetic evidence suggests a closer, though still tenuous, link to Chibchan-speaking groups from the Isthmus of Panama. However, this connection remains incomplete and raises more questions than answers. Around 6,000 years ago, these hunter-gatherers transitioned to agriculture and settled in the Bogotá Altiplano. Then, they mysteriously vanished from the genetic record. Unlike the Anzick-1 child of the Clovis culture or ancient Channel Islands residents whose DNA traces through modern populations, these ancient Colombians stand alone, without clear descendants. Why these people's DNA doesn't align with others is still uncertain. One theory suggests that as these groups migrated and mingled with others, their genetic markers diluted over time. Another possibility is that they represent a unique, now-extinct lineage. 'This area has long been a crossroads of culture and language, where ancient people from Central and South America converged,' the researchers noted. 'Understanding their history may illuminate broader patterns of human migration across the continent.' Further research in neighboring areas, like western Colombia, Venezuela, and Ecuador, is planned to fill the gaps. For now, these ancient Colombians remain a genetic mystery, hinting at forgotten migrations and lost connections that shaped the Uncover DNA Puzzle: 6,000-Year-Old Remains Reveal Mysterious Ancestors first appeared on Men's Journal on Jun 3, 2025
