MIT researchers discover bacteria’s new antiviral defense system

Posted by in categories: bioengineering, biotech/medical, chemistry, genetics, life extension

Specific proteins in prokaryotes detect viruses in unexpectedly direct ways.

Bacteria use a variety of defense strategies to fight off viral infection. STAND ATPases in humans are known to respond to bacterial infections by inducing programmed cell death in infected cells. Scientists predict that many more antiviral weapons will be discovered in the microbial world in the future. Scientists have discovered a new unexplored microbial defense system in bacteria.

Researchers uncovered specific proteins in prokaryotes (bacteria and archaea) that detect viruses in unexpectedly direct ways, recognizing critical parts of the viruses and causing the single-celled organisms to commit suicide to stop the infection within a microbial community, according to a press release published in the official website of the Massachusetts Institute of Technology (MIT) on Thursday.

Scientists win 2015 Nobel Prize for Chemistry for work on DNA repair

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

Circa 2015


“Their work has provided fundamental knowledge of how a living cell functions and is, for instance, used for the development of new cancer treatments,” the Royal Swedish Academy of Sciences said.

Thousands of alterations to a cell’s genome occur every day due to spontaneous changes and damage by radiation, free radicals and carcinogenic substances — yet DNA remains astonishingly intact.

Population genomic analysis of elongated skulls reveals extensive female-biased immigration in Early Medieval Bavaria

Posted by in categories: biotech/medical, genetics

This extensive research actually details the possibility of unknown origins of these elongated human skulls which many think to this day are some form of exterrestial in origin or at the very least unknown in origin which actually nearly uproots most know origin stories.


Modern European genetic structure demonstrates strong correlations with geography, while genetic analysis of prehistoric humans has indicated at least two major waves of immigration from outside the continent during periods of cultural change. However, population-level genome data that could shed light on the demographic processes occurring during the intervening periods have been absent. Therefore, we generated genomic data from 41 individuals dating mostly to the late 5th/early 6th century AD from present-day Bavaria in southern Germany, including 11 whole genomes (mean depth 5.56×). In addition we developed a capture array to sequence neutral regions spanning a total of 5 Mb and 486 functional polymorphic sites to high depth (mean 72×) in all individuals. Our data indicate that while men generally had ancestry that closely resembles modern northern and central Europeans, women exhibit a very high genetic heterogeneity; this includes signals of genetic ancestry ranging from western Europe to East Asia. Particularly striking are women with artificial skull deformations; the analysis of their collective genetic ancestry suggests an origin in southeastern Europe. In addition, functional variants indicate that they also differed in visible characteristics. This example of female-biased migration indicates that complex demographic processes during the Early Medieval period may have contributed in an unexpected way to shape the modern European genetic landscape. Examination of the panel of functional loci also revealed that many alleles associated with recent positive selection were already at modern-like frequencies in European populations ∼1,500 years ago.

Cedars-Sinai Creates Computer Models of Brain Cells

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

Realistic and complex models of brain cells, developed at Cedars-Sinai with support from our scientists and our #openscience data, could help answer questions a… See more.


Cedars-Sinai investigators have created bio-realistic and complex computer models of individual brain cells—in unparalleled quantity.

Their research, published today in the peer-reviewed journal Cell Reports, details how these models could one day answer questions about neurological disorders—and even human intellect—that aren’t possible to explore through biological experiments.

New Molecule Discovered That Strongly Stimulates Hair Growth

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

A team at the University of California, Irvine, has identified a signaling molecule that potently stimulates hair growth.

A signaling molecule known as SCUBE3, which was discovered by researchers at the University of California, Irvine, has the potential to cure androgenetic alopecia, a prevalent type of hair loss in both women and men.

The research, which was recently published in the journal Developmental Cell, uncovered the precise mechanism by which the dermal papilla cells, specialized signal-producing fibroblasts found at the bottom of each hair follicle, encourage new development. Although the critical role dermal papilla cells play in regulating hair growth is widely established, the genetic basis of the activating chemicals involved is little understood.

The seeds of innovation appear to be seedless. According to game-changing research led by our very own Dr. Lior Rubinovich, it is now finally possible to grow avocado plants solely from tissue culture. Why is this good? Aside from being free of deformities, disease-proof, and significantly fast-growing – cultivated avocado plants mean genetic uniformity, which implies that all plants originate from the same delicious, nutritious, and healthy tissue. The founding of Bestree means a great deal for the northern region of Israel, both financially and innovatively. Therefore, we are proud to share this inspiring research with the rest of the world!

Researchers discover one of the largest known bacteria-to-animal gene transfers inside a fruit fly

Posted by in categories: biotech/medical, genetics

A fruit fly genome is not a just made up of fruit fly DNA—at least for one fruit fly species. New research from the University of Maryland School of Medicine’s (UMSOM) Institute for Genome Sciences (IGS) shows that one fruit fly species contains whole genomes of a kind of bacteria, making this finding the largest bacteria-to-animal transfer of genetic material ever discovered. The new research also sheds light on how this happens.

The IGS researchers, led by Julie Dunning Hotopp, Ph.D., Professor of Microbiology and Immunology at UMSOM and IGS, used new genetic long-read sequencing technology to show how genes from the bacteria Wolbachia incorporated themselves into the fly genome up to 8,000 years ago.

The researchers say their findings show that unlike Darwin’s finches or Mendel’s peas, isn’t always small, incremental, and predictable.

New DNA repair-kit successfully fixes hereditary disease in patient-derived cells

Posted by in categories: biotech/medical, genetics

Genetic mutations which cause a debilitating hereditary kidney disease affecting children and young adults have been fixed in patient-derived kidney cells using a potentially game-changing DNA repair-kit. The advance, developed by University of Bristol scientists, is published in Nucleic Acids Research.

In this new study, the international team describe how they created a DNA repair vehicle to genetically fix faulty podocin, a common genetic cause of inheritable Steroid Resistant Nephrotic Syndrome (SRNS).

Podocin is a protein normally located on the surface of specialized and essential for . Faulty podocin, however, remains stuck inside the cell and never makes it to the surface, terminally damaging the podocytes. Since the disease cannot be cured with medications, gene therapy which repairs the causing the faulty podocin offers hope for patients.
