A team of researchers led by Professor Alexander B. Niculescu at Indiana University School of Medicine has developed a groundbreaking RNA biomarker blood test capable of assessing the severity of depression and predicting the risk of future severe depression or bipolar disorder. This innovative test builds on previous work identifying blood biomarkers linked to suicidality and post-traumatic stress disorder, with findings published in *Molecular Psychiatry*. Over four years and involving more than 300 participants, the team identified 26 key biomarkers through a rigorous four-step process, ultimately enabling tailored medication for patients. Niculescu emphasized the importance of these blood tests in providing objective assessments, particularly in a field where subjective self-reports can be unreliable. The study also revealed a connection between circadian rhythm genes and mood disorders, shedding light on seasonal symptom variations. This advancement represents a significant step towards integrating precision medicine into psychiatry, aiming to improve patient outcomes. 
Published: May 14 2025, 9 pmeznews.inScientists have identified a strain of the opportunistic bacterium _Pseudomonas aeruginosa_, commonly associated with hospital infections, that can break down biodegradable plastics used in medical devices. This discovery, made in the UK, centers on an enzyme called Pap1, which was found in _P. aeruginosa_ isolated from a wound. The enzyme effectively degrades polycaprolactone (PCL), a material prevalent in sutures, catheters, and other medical tools. This capability may explain the bacterium's persistence in clinical environments, as it can compromise the integrity of medical devices, potentially increasing infection risks. The research also revealed that the presence of Pap1 enhances the bacterium's ability to form biofilms, which are resistant to antibiotics. The findings underscore the need for incorporating antimicrobial components into PCL devices to mitigate infection risks. The study is published in *Cell Reports*, and researchers are now exploring whether other pathogens possess similar plastic-degrading abilities.
Published: May 15 2025, 12 ameznews.inA recent analysis of data from NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission has revealed significant differences between the Moon's nearside and far side, extending beyond surface appearances to the interior structure. Researchers found that the nearside is warmer and more geologically active, with a mantle that may be 2-3% "softer" and temperatures 100 to 200°C higher than the far side, likely due to radioactive materials. This study, led by Dr. Ryan Park, produced the most detailed gravitational map of the Moon to date, highlighting variations in topography, crustal thickness, and heat-producing elements. These findings not only enhance our understanding of the Moon's volcanic history but also have practical implications for future lunar exploration, as the detailed gravity map will aid in developing navigation systems essential for upcoming missions. The research is published in the journal Nature.
Published: May 14 2025, 9 pmeznews.inUK researchers from King's College London have developed a blood test that could revolutionize the treatment of depression by identifying the most effective medications for patients. Published in the *International Journal of Neuropsychopharmacology*, the study highlights two biological markers of inflammation—interleukin-1beta and macrophage migration inhibitory factor (MIF)—which are often found in patients who do not respond well to standard antidepressants. The presence of these markers suggests that inflammation may hinder the effectiveness of such medications. By detecting high levels of these markers, doctors could prescribe anti-inflammatory drugs to improve treatment outcomes. Although the initial trial involved only 140 participants, lead author Professor Carmine Pariante emphasized the need for larger studies. With approximately 350 million people affected by depression globally, this advancement offers hope for more tailored and effective treatment options, although patients are advised to consult their doctors before making any changes to their medication.
Published: May 14 2025, 10 pmeznews.inThe White House has dismissed speculation about extraterrestrial involvement in the recent downing of four flying objects over North America, with Press Secretary Karine Jean-Pierre stating there is "no indication of aliens or extraterrestrial activity." The latest object, described as an "octagonal structure" with strings, was shot down by F-16 fighter jets over Lake Huron on February 12, after being detected over Montana. This incident follows the January 28 sighting of a Chinese high-altitude balloon, which the US and Canada claim was for espionage, while China insists it was for meteorological purposes. The military has launched a task force to recover and analyze the debris from the latest object, which poses a potential hazard to civil aviation. Meanwhile, tensions between the US and China have escalated, with China accusing the US of violating its airspace with high-altitude balloons, leading to the postponement of a planned visit by US Secretary of State Antony Blinken.
Published: May 12 2025, 8 ameznews.inA group of independent researchers from the US is focusing on the Durupınar site in eastern Turkey, a geological formation resembling a ship, which they believe may be the resting place of Noah's Ark. First identified in 1948, the site gained attention in the late 20th century through claims by amateur archaeologist Ron Wyatt, who asserted it was the Ark's landing site, alongside other biblical locations. However, experts, including Joe Zias from the Israel Antiquities Authority, have dismissed Wyatt's assertions as lacking scientific credibility. Despite multiple geophysical surveys conducted by private groups, no conclusive evidence has emerged, leading many to view the site as a natural formation. The California-based Noah’s Ark Scan team plans to conduct further non-invasive studies before considering excavation, emphasizing the need for careful planning and preservation. While the notion of a global flood lacks scientific backing, the prevalence of flood myths across cultures raises intriguing questions about their origins and meanings.
Published: May 14 2025, 7 pmeznews.inA video shared by Republican Congressman Tim Moore showcasing a hidden passageway beneath the Lincoln Room in the US Capitol has sparked concern online regarding potential security risks. In the footage, Moore highlights the historical significance of the passage, claiming it may have been used by British soldiers during the War of 1814 when they attacked Washington, although this remains unverified. The post elicited mixed reactions, with some users cautioning against revealing such information, fearing it could compromise security. Moore later clarified that the staircase is a sealed-off exit, not a tunnel, and has been closed for decades, emphasizing that it is public knowledge. The Lincoln Room, named in 2019, was once the House post office during Lincoln's congressional tenure, serving as a vital meeting place for the future president.
Published: May 14 2025, 8 pmeznews.inIn a groundbreaking experiment, researchers at the University of Tsukuba in Japan have successfully stimulated cicadas to perform Pachelbel’s Canon in D, showcasing the potential of insect cyborgs. By using electrodes similar to muscle-toning devices, the team created a biological speaker that allowed the cicadas to produce music before flying away unharmed. This innovative approach falls under biomimetics, which seeks to solve human challenges by mimicking nature. The cicadas, capable of reaching volumes of 120 decibels with minimal electrical input, could serve as low-power acoustic actuators for disaster signaling or environmental monitoring. Authors Yuga Tsukuda and Naoto Nishida emphasized the importance of maintaining the insects' natural agency, noting that their unpredictable variations added a unique charm to the performance. While the applications remain experimental, the research hints at a future where cicada cyborgs could play a vital role in communication and safety.
Published: May 10 2025, 4 ameznews.inFlamingos have been revealed as active hunters rather than passive filter feeders, employing sophisticated techniques to trap prey in water, according to a new study led by Dr. Victor Ortega Jiménez from the University of California, Berkeley. The research highlights how these pink birds create tiny tornadoes in the water using their uniquely shaped feet and the chattering of their bills, significantly increasing their catch of brine shrimp and other small organisms. By filming flamingos feeding underwater and developing computer models, the team demonstrated that the birds' webbed feet stir up sediment and create vortices that direct food towards their beaks. This method enhances their feeding efficiency, allowing them to capture prey seven times more effectively. The findings not only shed light on flamingo feeding behavior but may also offer insights into water dynamics that could aid in environmental cleanup efforts, such as removing microplastics. The study is published in the Proceedings of the National Academy of Sciences.
Published: May 14 2025, 4 pmeznews.inA photo of a massive huntsman spider, affectionately named Charlotte, has gone viral, prompting mixed reactions online, with some questioning its authenticity and others suggesting drastic measures. The spider, which has been living with Australian homeowner Jake Gray for a year, is indeed real and has become a part of the family. Gray explained that they tolerate huntsman spiders due to their appetite for cockroaches and avoid toxic pest control methods. Despite its intimidating appearance, the Banded huntsman, or Sydney huntsman, is generally harmless, preferring to flee rather than bite. Experts advise that if one encounters such a spider, the best approach is to remain calm, use a container to capture it, and release it outside, as bites are rare and typically non-venomous. Gray even hopes Charlotte will continue to grow, highlighting the unique relationship some Australians have with these large arachnids.
