How Machine Learning Is Identifying New, Better Drugs

Posted by in categories: biotech/medical, chemistry, information science, robotics/AI

When Dr. Robert Murphy first started researching biochemistry and drug development in the late 1970s, creating a pharmaceutical compound that was effective and safe to market followed a strict experimental pipeline that was beginning to be enhanced by large-scale data collection and analysis on a computer.

Now head of the Murphy Lab for computational biology at Carnegie Mellon University (CMU), Murphy has watched over the years as data collection and artificial intelligence have revolutionized this process, making the drug creation pipeline faster, more efficient, and more effective.

Recently, that’s been thanks to the application of machine learning—computer systems that learn and adapt by using algorithms and statistical models to analyze patterns in datasets—to the drug development process. This has been notably key to reducing the presence of side effects, Murphy says.

The durability of immunity against reinfection

Posted by in categories: biotech/medical, health

The timeframe for reinfection is fundamental to numerous aspects of public health decision making. As the COVID-19 pandemic continues, reinfection is likely to become increasingly common. Maintaining public health measures that curb transmission—including among individuals who were previously infected with SARS-CoV-2—coupled with persistent efforts to accelerate vaccination worldwide is critical to the prevention of COVID-19 morbidity and mortality.

Scientists Rewired The Brain of a Mutant Worm Using Parts From a Hydra

Posted by in categories: biotech/medical, chemistry, education, genetics, neuroscience

Brains aren’t the easiest of organs to study, what with their delicate wiring and subtle whispering of neurotransmitter messages. Now, this research could be made a little easier, as we’ve learned we can swap some critical chemical systems with the host animal being none the wiser.

In a proof-of-concept study run by a team of US researchers, the microscopic worm Caenorhabditis elegans was genetically gifted pieces of a nervous system taken from a radically different creature – a curious freshwater organism known as Hydra.

The swap wasn’t unlike teaching a specific brain circuit a foreign language, and finding it performs its job just as well as before.

Mapping proteins could offer a clearer view of what’s driving cancer

Posted by in categories: biotech/medical, genetics

Genetic information can be messy. Mapping proteins could offer a clearer view of what’s driving cancer.


Scientists have unveiled new maps of the protein networks underlying different types of cancer, offering a potentially clearer way to see what’s driving the disease and to find therapeutic targets.

Sequencing the genetic information of tumors can provide a trove of data about the mutations contained in those cancer cells. Some of those mutations help doctors figure out the best way to treat a patient, but others remain more of a mystery than a clear instruction manual. Many are exceedingly rare, or there are so many mutations it’s not clear what’s fueling the cancer.

Atlas maps gene activity, accessibility in developing brain

Posted by in categories: biotech/medical, genetics, neuroscience

A new resource profiles gene expression and the accessibility of DNA in single cells across the developing human cerebral cortex and may help scientists decipher the effects of noncoding mutations linked to autism.

Brain-cleaning sleeping cap gets US Army funding

Posted by in categories: biotech/medical, neuroscience, wearables

Interesting.


Everybody knows sleep is important, but there’s still a lot we don’t understand about what it actually does to the brain – and how its benefits could be boosted. To investigate, the US Army has awarded researchers at Rice University and other institutions a grant to develop a portable skullcap that can monitor and adjust the flow of fluid through the brain during sleep.

Most of us are familiar with the brain fog that comes with not getting enough sleep, but the exact processes going on in there remain mysterious. In 2012 scientists made a huge breakthrough in the field by discovering the glymphatic system, which cleans out toxic waste products from the brain during deep sleep by flushing it with cerebrospinal fluid. Disruptions to sleep – and therefore the glymphatic system – have been increasingly associated with neurological disorders such as Alzheimer’s.

Merck’s COVID pill cuts deaths, hospitalisations

Posted by in categories: biotech/medical, health

By half, it would soon ask health officials around the world to authorise its use ⤵️.


If authorised for use, it would be the first pill shown to treat COVID and a major step in controlling the pandemic.
