Scientists are producing deadly zoonoses on this tiny German island

On a small, unassuming German island called Riems lies one of the oldest virus research institutes in the world. And also one of the most dangerous.

The Friedrich Loeffler Institute is closed to the public. To access the island, approved visitors must first cross a small stretch of the Baltic Sea via a dam, which can be closed immediately in case of an outbreak. To enter the facility, they must take a shower and put on protective clothing. Inside, scientists study some of the world’s most deadly viruses, including bird flu, Ebola and mad cow disease.

The German island of Riems is home to some of the most dangerous virology research on the planet.

The fractured genome of HeLa cells

Circa 2013 o,., o! Unlimited cell division. Basically this means a possibility for unlimited cell division throughout the human body if used in crispr.

Whole-genome sequencing of the widely used HeLa cell line provides a nucleotide-resolution view of a greatly mutated and in some places shattered genome.

Researchers develop pressure-quench process to enhance superconductivity toward goal of wasting zero energy

In the simplest terms, superconductivity between two or more objects means zero wasted electricity. It means electricity is being transferred between these objects with no loss of energy.

Many naturally occurring elements and minerals like lead and mercury have superconducting properties. And there are modern applications that currently use materials with superconducting properties, including MRI machines, maglev trains, electric motors and generators.

Usually, superconductivity in materials happens in low-temperature environments or at high temperatures at very high pressures. The holy grail of superconductivity today is to find or create materials that can transfer energy between each other in a non-pressurized environment.

CRISPR On-Off Switch Will Help Unlock the Secrets of Our Immune System

Can we turn up—or dial down—their fervor by tweaking their genes?

Enter a new kind of CRISPR. Known mostly as a multi-tool to cut, snip, edit, or otherwise kneecap an existing gene, this version—dubbed CRISPRa—forcibly turns genes on. Optimized by scientists at Gladstone Institutes and UC San Francisco, the tool is counterbalanced by CRISPRi—“i” for “interference,” which, you guessed it, interferes with the gene’s expression.

Though previously used in immortal cells grown in labs, this is the first time these CRISPR tools are rejiggered for cells extracted from our bodies. Together, the tools simultaneously screened nearly 20,000 genes in T cells isolated from humans, building a massive genetic translator—from genes to function—that maps how individual genes influence T cells.

Stanford Scientists Say Brain Magnets Can Relieve Depression

Researchers at the Stanford University School of Medicine say that they were able to treat depression in patients by stimulating their brains with magnets.

In a study published on Friday 0, the researchers found that nearly 80 percent of patients had experienced remission of their depression after the procedure, which is called Stanford neuromodulation therapy (SNT). The technique is a modified form of transcranial magnetic stimulation (rTMS) and works by delivering high doses of magnetic pulses into a patient’s brain with a device containing magnetic coils placed outside of their skull.

The treatment takes just five days and is customized to each patient based on an MRI scan which shortens the typical timeline of rTMS treatment from a span of weeks into days.
