Stiffer colon could signal risk of early-onset colorectal cancer

Increased stiffness of the colon, spurred by chronic inflammation, may encourage the development and progression of early-onset colorectal cancer (CRC), a study co-led by UT Southwestern Medical Center researchers suggests. The findings, published in Advanced Science, could lead to new ways to prevent and treat this deadly subset of CRC.

“We consider this study a significant advancement toward identifying those at risk of early-onset CRC and finding new ways to treat them,” said Emina Huang, M.D., M.B.A., Professor of Surgery in the Division of Colon and Rectal Surgery and Executive Vice Chair of Research for Surgery at UT Southwestern. She is also Professor of Biomedical Engineering and in the Harold C. Simmons Comprehensive Cancer Center.

UT Southwestern partnered with researchers from The University of Texas at Dallas on the study.

Physicists & Philosophers debunk The Fine Tuning Argument

The Fine-Tuning Argument is often seen as the best argument for the existence of God. Here we have assembled some of the world’s top physicists and philosophers to offer a reply. Not every critic of the argument comes from the same perspective. Some doubt there is a problem to be solved whilst others agree it is a genuine problem but think there are better solutions than the God hypothesis. Some like the multiverse and anthropics other don’t. We have tried to represent these different approaches and so it should be taken as given, that not all of the talking heads agree with each other. Nevertheless, they all share the view that the fine-tuning argument for God does not work. Nor are all the objectors atheist, Hans Halvorson offers what we think is a strong theological objection to the argument. This film does not try to argue that God doesn’t exist only that the fine-tuning argument is not a good reason to believe in God. Most of the footage was filmed exclusively for this film with some clips being re-used from our Before the Big Bang series, which can be viewed here: • Before the Big Bang 5: The No Boundary Pro… All of the critics of the fine tuning argument that appear were sent a draft of the film more than a month before release and asked for any objections either to their appearance, the narration or any other aspect of the film. No objections were raised, and many replies were extremely positive and encouraging. A timeline of the subjects covered is below:
(We define God as a perfect Omni immaterial mind as for example modern Christians and Muslims advocate, there are other conceptions of God which our video does not address).
Just to be clear, this is a polemical film arguing against the fine tuning argument.

Brain immune cells may drive more damage in females than males with Alzheimer’s

More than 7 million Americans have Alzheimer’s disease, and two-thirds of them are women, according to the Alzheimer’s Association. The O’Banion Lab at the Del Monte Institute for Neuroscience at the University of Rochester has long been studying this disease and is looking more closely at the differences between male and female brains.

“It is well documented that males and females are diagnosed with Alzheimer’s disease at different rates,” said M. Kerry O’Banion, MD, Ph.D., professor of Neuroscience and Neurology. “But we still do not have a great understanding of why this is the case. We can only improve any possible treatment or prevention of this disease if we know the why, when, and where these differences are occurring.”

Bird feeders have caused a dramatic evolution of California hummingbirds

Evolution doesn’t always take thousands or millions of years. Sometimes it happens right before our eyes.

Such is the case with the Anna’s hummingbird, a species that has undergone a dramatic transformation in just a few generations, all thanks to the advent of hummingbird feeders.

Beaks have grown longer and larger, and ranges have expanded to follow the feeders.

Antibiotic resistance forecast to kill 39 million people by 2050

According to the most comprehensive study to date, the global death toll from antibiotic resistance is expected to reach 1.9 million people annually by 2050.

AI model forecasts speech development in deaf children after cochlear implants

An AI model using deep transfer learning—the most advanced form of machine learning—has predicted spoken language outcomes with 92% accuracy from one to three years after patients received cochlear implants (implanted electronic hearing device).

The research is published in the journal JAMA Otolaryngology–Head & Neck Surgery.

Although cochlear implantation is the only effective treatment to improve hearing and enable spoken language for children with severe to profound hearing loss, spoken language development after early implantation is more variable in comparison to children born with typical hearing. If children who are likely to have more difficulty with spoken language are identified prior to implantation, intensified therapy can be offered earlier to improve their speech.

Modified tau thwarts aggregation in neurodegenerative disease—while retaining its biological function

A designer version of the tau protein, developed by a team led by UT Southwestern Medical Center researchers, maintains its biological function while resisting aggregation, a pathological trait linked to neurodegenerative diseases called tauopathies.

These findings, reported in Structure, could lead to new treatments for conditions including Alzheimer’s disease, frontotemporal dementia, chronic traumatic encephalopathy (CTE), and progressive supranuclear palsy.

“This is the first step toward creating a molecule that could, in principle, replace a protein that’s pathogenic (disease-causing) while still retaining its normal function,” said study leader Lukasz Joachimiak, Ph.D., Associate Professor in the Center for Alzheimer’s and Neurodegenerative Diseases and of Biochemistry and Biophysics at UT Southwestern.
