New X-ray capability could find wide application in environmental and medical research, as well as the development of batteries and microelectronic devices.
Scientists at Argonne National Laboratory and various universities have successfully used X-ray beams to analyze a single atom.
An atom is the smallest component of an element. It is made up of protons and neutrons within the nucleus, and electrons circling the nucleus.
In a groundbreaking study published in Cell Genomics, a team of scientists led by Chris Walsh from the Howard Hughes Medical Institute and Boston Children’s Hospital has unveiled intriguing findings about the genetic factors contributing to schizophrenia and introduces a novel avenue for investigating the causes of psychiatric disorders.
Health care professionals are overcoming these obstacles with a new treatment called hepatic artery infusion pump chemotherapy that shrinks liver tumors, giving more people a chance for surgery. This treatment also can shrink tumors in the bile ducts inside the liver, called intrahepatic cholangiocarcinoma.
“Our goal is to expand the number of patients who could be offered curative treatment,” says Dr. Thiels. “We are also aiming to reduce the risk of cancer recurring in people with high-risk liver tumors.”
The hepatic artery carries oxygen-rich blood to the liver. A hepatic artery pump delivers chemotherapy directly into the liver’s blood supply. Because chemotherapy from the pump only reaches the liver, the approach can use higher doses to shrink liver tumors more effectively. “We can often achieve a higher response rate than conventional chemotherapy,” says Dr. Thiels.
A study conducted by researchers from the Department of Neurology at MedUni Vienna and University Hospital Vienna has demonstrated for the first time that the diagnosis of multiple sclerosis (MS) can be significantly improved by additionally measuring the thickness of retinal layers in the eye.
Use of the procedure, which is already available at the Departments of MedUni Vienna and University Hospital Vienna, helps to detect the condition at an earlier stage and predict its progression more accurately. This can lead to a decisive increase in the chance of improved patient outcomes. The findings have been published in the journal Neurology.
As part of their investigation, the research team headed by Gabriel Bsteh and Thomas Berger of the Department of Neurology at MedUni Vienna and University Hospital Vienna collaborated with colleagues from MedUni Vienna and University Hospital Vienna’s Department of Ophthalmology and Optometrics to examine 267 MS patients over a period of five years.
In a recent article published in Nature communications*, researchers described a technique of capturing two-dimensional (2D) light patterns into deoxyribonucleic acid (DNA) and using high-throughput next-generation sequencing to retrieve recorded images.

Scientists at the National University of Singapore (NUS) have used bacteria for recording, storing, and retrieving images in DNA. This biological analog to a digital camera, which the authors have named “BacCam,” is a crucial step for DNA data storage techniques and the merging of biological and electronic systems.
The article, “A biological camera that captures and stores images directly into DNA,” was published in Nature Communications.
Prior to this publication, there were two landmark papers that addressed either the use of cells to capture light or the storage of images into DNA, but not the two together. In May 2017, researchers from the lab of Christopher Voigt, PhD, at the Massachusetts Institute of Technology (MIT) developed a system to produce ‘color photographs’ on bacterial culture plates by controlling pigment production and to redirect metabolic flux by expressing CRISPRi guide RNAs. Two months later, researchers in the lab of George Church, PhD, at Harvard Medical School demonstrated a method for encoding images via de novo DNA synthesis before insertion into the bacterial genome.
New gadget can map electrical activity and deliver electrical stimuli to stop atrial fibrillation, before dissolving into the body.
Nearly 800K people fall victim to a heart attack in the US each year. A recent study undertaken by a team of researchers at Northwestern and George Washington (GW) universities has developed a new device to monitor and treat heart disease and dysfunctions in the aftermath of heart-related incidents.
The device seems to hold promise for providing critical support during the days, weeks, or months following heart problems. According to the researchers convey that the new technology harmlessly dissolves inside the body and skips the need for extraction.

New research from the University of Montana and its partners suggests artificial intelligence can match the top 1% of human thinkers on a standard test for creativity.
The study was directed by Dr. Erik Guzik, an assistant clinical professor in UM’s College of Business. He and his partners used the Torrance Tests of Creative Thinking, a well-known tool used for decades to assess human creativity.
The researchers submitted eight responses generated by ChatGPT, the application powered by the GPT-4 artificial intelligence engine. They also submitted answers from a control group of 24 UM students taking Guzik’s entrepreneurship and personal finance classes. These scores were compared with 2,700 college students nationally who took the TTCT in 2016. All submissions were scored by Scholastic Testing Service, which didn’t know AI was involved.
