Melanoma study finds mRNA vaccine combined with standard treatment could reduce recurrence

Posted by in category: biotech/medical

In a stage two clinical trial, researchers found that adding an mRNA cancer vaccine to standard treatment reduced the chances for melanoma recurrence or death by 44 percent. NBC News’ Kristen Dahlgren spoke to one of the study’s doctors and a patient for more details.

Elon Musk says he ‘learned a lot today’ after cancelling SpaceX’s giant rocket launch at last minute

Posted by in categories: Elon Musk, satellites

No people or satellites were aboard. There won’t be another try until at least Wednesday.

“Learned a lot today,” Musk tweeted after the flight was postponed.

The company plans to use Starship to send people and cargo to the moon and, ultimately, Mars.

Extrachromosomal DNA detection in Barrett’s esophagus linked to cancer development

Posted by in category: biotech/medical

A multi-institution study that included researchers from Stanford University, the University of California at San Diego, the University of Cambridge, the Fred Hutchinson Cancer Center and others has looked into the development of extrachromosomal DNA in patients with esophageal adenocarcinoma or Barrett’s esophagus.

In the paper, “Extrachromosomal DNA in the cancerous transformation of Barrett’s oesophagus,” published in Nature, researchers identify previously unknown aspects of extrachromosomal DNA presence and their potential role in Barrett’s esophagus. David H. Wang has published a News & Views piece in the same journal discussing the study.

Barrett’s esophagus is a pre-cancerous tissue abnormality that affects about 1.6% of the U.S. population. The condition is mostly harmless, defined by cells in the esophagus lining that become more intestinal-like and is frequently associated with heartburn and acid regurgitation.

A new breakthrough in Alzheimer’s disease research: Visualizing reactive astrocyte-neuron interaction

Posted by in categories: biotech/medical, neuroscience

Recently, a team of South Korean scientists led by Director C. Justin Lee of the Center for Cognition and Sociality within the Institute for Basic Science made a discovery that could revolutionize both the diagnosis and treatment of Alzheimer’s Disease. The group demonstrated a mechanism where the astrocytes in the brain uptake elevated levels of acetates, which turns them into hazardous reactive astrocytes. They then went on to further develop a new imaging technique that takes advantage of this mechanism to directly observe the astrocyte-neuron interactions.

Alzheimer’s disease (AD), one of the major causes of dementia, is known to be associated with neuroinflammation in the brain. While traditional neuroscience has long believed that amyloid beta plaques are the cause, treatments that target these plaques have had little success in treating or slowing the progression of Alzheimer’s disease.

On the other hand, Director C. Justin Lee has been a proponent of a novel theory that reactive astrocytes are the real culprit behind Alzheimer’s disease. Reactive astrogliosis, a hallmark of neuroinflammation in AD, often precedes neuronal degeneration or death.

Schizophrenia: Network disruptions in the brain may be a factor

Posted by in category: neuroscience

In the brains of people without schizophrenia, concepts are organized into specific semantic domains and are globally connected, enabling coherent thought and speech.

In contrast, the researchers reported that the semantic networks of people with schizophrenia were disorganized and randomized. These impairments in semantics and associations contribute to delusion and incoherent speech.
