Preparing for the Future of Artificial Intelligence
Posted by Amnon H. Eden in categories: biotech/medical, computing, health, robotics/AI
Today, we’re announcing a new series of workshops and an interagency working group to learn more about the benefits and risks of artificial intelligence.
There is a lot of excitement about artificial intelligence (AI) and how to create computers capable of intelligent behavior. After years of steady but slow progress on making computers “smarter” at everyday tasks, a series of breakthroughs in the research community and industry have recently spurred momentum and investment in the development of this field.
Today’s AI is confined to narrow, specific tasks, and isn’t anything like the general, adaptable intelligence that humans exhibit. Despite this, AI’s influence on the world is growing. The rate of progress we have seen will have broad implications for fields ranging from healthcare to image- and voice-recognition. In healthcare, the President’s Precision Medicine Initiative and the Cancer Moonshot will rely on AI to find patterns in medical data and, ultimately, to help doctors diagnose diseases and suggest treatments to improve patient care and health outcomes.

Faster, cheaper way to produce new antibiotics
Posted by Karen Hurst in category: biotech/medical
Nice
A novel way of synthesising a promising new antibiotic has been identified by scientists at the University of Bristol. By expressing the genes involved in the production of pleuromutilin in a different type of fungus, the researchers were able to increase production by more than 2,000 per cent.
With resistance growing to existing antibiotics, there is a vital and urgent need for the discovery and development of new antibiotics that are cost effective. Promising developments are derivatives of the antibiotic pleuromutilin, which are isolated from the mushroom Clitopilus passeckerianus.
These new compounds are some of the only new class of antibiotics to join the market recently as human therapeutics. Furthermore, with their novel mode of action and lack of cross-resistance, pleuromutilins and their derivatives represent a class with further great potential, particularly for treating resistant strains such as methicillin-resistant Staphylococcus aureus (MRSA) and extensively drug resistant tuberculosis (XTB).

Endometrial Cancer Genetic Risk Factors Double
Posted by Karen Hurst in categories: biotech/medical, genetics
The strength of genome-wide association studies (GWAS) lies in their ability to identify new disease biomarkers through large-scale genomic comparisons of afflicted individuals and unaffected controls. Now, using this powerful technique, an international collaboration of researchers has identified five new gene regions that increase a woman’s risk of developing endometrial cancer—one of the most common cancers to affect women—taking the number of known gene regions associated with the disease to nine.
Endometrial cancer affects the lining of the uterus, typically presenting as an adenocarcinoma. Endometrial cancer is the sixth most common cancer in women worldwide and is the most common cancer of the female reproductive tract in developed countries, with over 320,000 new cases diagnosed in 2012.
Investigators at the University of Cambridge, Oxford University, and QIMR Berghofer Medical Research Institute in Brisbane studied the DNA of over 7000 women with endometrial cancer and 37,000 women without cancer to identify genetic variants that affected a woman’s risk of developing the disease.

Non-Identical Twins Run In Families: Scientists Find Common Genes
Posted by Karen Hurst in categories: biotech/medical, genetics
The likelihood of giving birth to non-identical twins run in the families, suggests a new study conducted by a team of scientists. The team based their conclusion on the identification of two genetic variants in women who give birth to twins.
A number of factors have previously been linked to why some women give birth to non-identical twins. However, no study ever characterized the properties of the genes the contribute to this outcome.
The latest study looks at the genetic makeup of the mother and explains how mother’s genes can lead to the birth of non-identical twins. During the study, the research team specifically compared the genomes of the non-identical twins’ mothers to look for any common genetic variants between them.

Unique nano-capsules promise the targeted drug delivery
Posted by Karen Hurst in categories: biotech/medical, nanotechnology, physics
Gotta luv this.
An international team of researchers including the Lomonosov Moscow State University physicists has developed a completely new type of drug carrier for targeted delivery to the sick organ — the gel nano-capsules with a double shell. The results of the study were published in Scientific Reports.
This biotech company just got approval to try and bring clinically dead patients back to life.

Watch immune cells ‘glue’ broken blood vessels back together
Posted by Karen Hurst in categories: biotech/medical, genetics, neuroscience
Very cool!
As we age, tiny blood vessels in the brain stiffen and sometimes rupture, causing “microbleeds.” This damage has been associated with neurodegenerative diseases and cognitive decline, but whether the brain can naturally repair itself beyond growing new blood-vessel tissue has been unknown. A zebrafish study published on May 3 in Immunity describes for the first time how white blood cells called macrophages can grab the broken ends of a blood vessel and stick them back together.
“Microbleeding occurs very often in the human brain, particularly in elderly people,” says Lingfei Luo, a developmental geneticist at Southwest University in China. “We believe that this macrophage behavior is the major cellular mechanism to repair ruptures of blood vessels and avoid microbleeding in the brain.”
To simulate a human brain microbleed, Luo and his colleagues shot lasers into the brains of live zebrafish to rupture small blood vessels, creating a clean split in the tissue with two broken ends. Then, the researchers used a specialized microscope to watch what happened next.
