New genetic tool could identify drug targets for diseases associated with metabolic dysfunction
2024-07-23
There’s a glaring gap in our knowledge of cell metabolism: in many cases, we still don’t know exactly how nutrients are transported into the cell. Without that understanding, it’s extremely difficult, if not impossible, to develop treatments for the many diseases linked to the protein transporters that drive metabolism. Now, a new study in Nature Genetics presents a tool to map these metabolic gene functions more precisely. The platform, dubbed GeneMAP, has already identified one key gene-metabolite association at the heart of mitochondrial metabolism.
GeneMAP was developed in the laboratory of Kivanç Birsoy, ...

Large language models don’t behave like people, even though we may expect them to
2024-07-23
CAMBRIDGE, MA – One thing that makes large language models (LLMs) so powerful is the diversity of tasks to which they can be applied. The same machine-learning model that can help a graduate student draft an email could also aid a clinician in diagnosing cancer.
However, the wide applicability of these models also makes them challenging to evaluate in a systematic way. It would be impossible to create a benchmark dataset to test a model on every type of question it can be asked.
In a new paper, MIT researchers took a different approach. They ...

Top Medicare advantage plans less available in disadvantaged areas
2024-07-23
Looking for a Medicare Advantage plan with a five-star quality rating? You’re less likely to find one available to you if you live in a county with higher poverty and unemployment, finds a new study published in JAMA Network Open.
These geographic disparities may be contributing to unequal health outcomes and limiting federal funds from reaching the regions most in need, according to the researchers.
“What this means is that Medicare beneficiaries living in counties with greater social disadvantage ...
Better carbon storage better carbon storage with stacked geology with stacked geology
2024-07-23
The overarching goal of all carbon capture and storage projects is the same: Keep carbon dioxide (CO2) emissions out of the atmosphere by storing them in the subsurface for good.
One way to do that is to inject the CO2 into a reservoir space that’s covered with a big lid – an impermeable caprock that can keep the gas in place and stop any upward flow in its tracks. That’s the model that petroleum exploration has relied on for decades when searching for oil traps, and it works for both oil and CO2. But according to research led by The University of Texas at Austin’s Bureau of Economic Geology, subsurface ...

Asexual reproduction usually leads to a lack of genetic diversity. Not for these ants.
2024-07-23
Genetic diversity is essential to the survival of a species. It’s easy enough to maintain if a species reproduces sexually; an egg and a sperm combine genetic material from two creatures into one, forming a genomically robust offspring with two distinct versions of the species’ genome.
Without that combination of different genetic makeups, asexually reproducing species typically suffer from a lack of diversity that can doom them to a limited run on Earth. One such animal should be the clonal raider ant, which produces daughter after genetically identical daughter directly from an unfertilized ovum ...

How does the brain respond to sleep apnea?
2024-07-23
Nearly 40 million adults in the U.S. have sleep apnea, and more than 30 million of them use a continuous positive airway pressure (CPAP) machine while sleeping. However, the machines tend to be expensive, clunky and uncomfortable — resulting in many users giving up on using them.
High blood pressure is often linked with sleep apnea because the brain works harder to regulate blood flow and breathing during sleep. A recent study at the University of Missouri offers new insight into the underlying mechanisms within the brain contributing ...
