Sample shapes of distant galaxies identified by the James Webb Space Telescope’s Cosmic Evolution Early Release Science (CEERS) survey. Credit: NASA, ESA, CSA, STScI, Steve Finkelstein (UT Austin), Micaela Bagley (UT Austin), Rebecca Larson (UT Austin) Data from NASA’s James Webb Space Telescope suggests that many early galaxies were long and thin, not disk-like or spherical.Columbia researchers analyzing images from NASA’s James Webb Space Telescope have found that galaxies in the early universe are often flat and…

Columbia University researchers reveal a sensitive adolescent period that shapes adult behavior through dopamine function, highlighting the complex impact of stimulant exposure on developing brains and potential psychiatric outcomes. Credit: SciTechDaily.com Drugs blocking dopamine transporters may be harmful for healthy teens but helpful for those with pathological dopamine hypofunction.In a breakthrough finding researchers at Columbia University Irving Medical Center identified a sensitive developmental period during…

Illustration of a diPUFA phospholipid, a type of lipid with two polyunsaturated fatty acyl tails, breaking through a cell’s outer lipid layer as the cell dies. New research has shown that diPUFA phospholipids are a key driver of a form of cell death known as ferroptosis. Credit: Nicoletta Barolini/Columbia UniversityScientists have discovered that a rare lipid type plays a pivotal role in ferroptosis, a form of cell death. This finding sheds light on the mechanisms of cell death in ferroptosis and opens up possibilities…

Credit: Cheng Lab/Columbia EngineeringColumbia Biomedical Engineer Ke Cheng has developed a technique that uses inhalation of exosomes, or nanobubbles, to directly deliver IL-12 mRNA to the lungs of mice.Lung cancer is one of the most common cancers and has one of the lowest survival rates in the world. Cytokines, which are small signaling…

A study by Columbia University Mailman School of Public Health and the City University of New York found that asthma is more prevalent among high school students who use cannabis than among non-users. Moreover, the prevalence of asthma increases with the frequency of cannabis use. Credit: SciTechDaily.comAsthma prevalence is higher in high school students who use cannabis compared to non-users, with increased frequency of use correlating with higher asthma rates.Asthma is more common among high school students who use…

By Columbia University School of Engineering and Applied Science February 10, 2024New research demonstrates how laser light can amplify the nonlinear optical properties of hexagonal boron nitride (hBN). The research successfully generated new optical frequencies and significantly increased third-harmonic generation, marking a significant advancement in the field of nonlinear optics and quantum material research.A recent study published in Nature Communications reveals that engineers from Columbia University, in…

A new study reveals a correlation between cannabis use and higher asthma rates in the U.S., with frequent users facing significantly increased risks. This research underscores the need for further investigation into cannabis’s impact on respiratory health.Recent research shows that cannabis use is linked to increased asthma prevalence, highlighting potential public health concerns as cannabis consumption rises.Asthma is more common among U.S. individuals who reported cannabis use in the past 30-days, with the odds of…

By Columbia University School of Engineering and Applied Science January 27, 2024An undergraduate-led team at Columbia Engineering used AI to challenge the forensic assumption that fingerprints from different fingers of the same person are unmatchable, discovering a new kind of forensic marker. Despite initial skepticism, their findings, which could revolutionize forensic science, were published in Science Advances. Credit: SciTechDaily.comColumbia engineers have built a new AI that shatters a long-held belief in…

Columbia University has banned the alleged perpetrators of a chemical attack that took place during a pro-Palestinian rally on Friday from the university’s campus.  In an email to students and staff, interim University Provost Dennis Mitchell wrote that since the incident, in which protesters reported being sprayed with “a foul-smelling substance that required students to seek medical treatment,” Columbia has been working with the New York City Police Department “in investigating what appear to have been serious…

A Columbia University study shows that positive adult-child relationships during childhood enhance adult mental health, regardless of adverse childhood experiences. The research indicates that social relationships, excluding peer relationships, reduce depression and anxiety risks, challenging traditional notions of resilience factors like family religiosity.
