Scientists Squeeze Entire Yeast Genome into Just One Chromosome

Two separate research groups used CRISPR gene editing to fuse entire sets of brewer’s yeast chromosomes together, resulting in two strains with just one and two chromosomes. Surprisingly, the changes had little effect on most functions of the yeast. Their findings could be monumental to the study of chromosomes and why their numbers vary from species to species.

Houseplants Could One Day Monitor Your Home Health

Researchers from the University of Tennessee Institute of Agriculture presented a concept of houseplants as aesthetically pleasing and functional alarm systems of home health. They have effectively connected two seemingly unrelated disciplines – plant sciences and architectural design. Genetically engineered houseplants could detect viruses, such as influenza virus, odors, and other volatile organic compounds that plants can “inhale” through their leaves.

Controversial CRISPR “Gene Drives” Tested in Mice

Researchers from the University of California tested gene-drive technology in mice. This controversial application of CRISPR, capable of altering the genomes of entire species, has been applied to mammals for the first time. Although the developed technology has a long way to go before being used for pest control in the wild, it could be useful in basic research.

Big Data Analysis Links Herpes Viruses with Alzheimer’s

Researchers from Arizona State University and the Icahn School of Medicine at Mount Sinai Indiana University made a large-scale analysis and used data from three different brain banks. They concluded that human herpes viruses are more abundant in the brains of Alzheimer’s patients and may play a role in regulatory genetic networks believed to be behind the onset of the disease. New possibilities for Alzheimer’s treatment, such as antiviral and immune therapy, are now open.

Why Is a Male Birth Control Pill Not Around Yet?

Men are still limited to only a few forms of birth control. Scientists are making constant progress but the birth control pill or any other hormonal contraceptives for men are still years away from being safe, reversible, and broadly available. In the past, low demand and focus on women contraceptives partly limited development. Now, more and more men want to take control over their own fertility.
