Finding blood clots before they wreak havoc

Finding blood clots before they wreak havoc | Biosciencia News | Scoop.it
Simple urine test developed by MIT engineers uses nanotechnology to detect dangerous blood clotting.
Biosciencia's insight:

Life-threatening blood clots can form in anyone who sits on a plane for a long time, is confined to bed while recovering from surgery, or takes certain medications.

The heart makers

How do you make a working human heart? Scientists can turn stem cells into beating heart cells, but getting them to organize into a 3D heart requires a scaff...
Biosciencia's insight:

For more than a decade, biologists have been able to turn embryonic stem cells into beating heart-muscle cells in a dish. With a little electrical pacemaking from the outside, these engineered heart cells even fall into step and maintain synchronous beating for hours.

Blocking boozy memories reduces risk of relapse

Blocking boozy memories reduces risk of relapse | Biosciencia News | Scoop.it
Molecule associated with learning and memory could be key to treating alcoholism.
Biosciencia's insight:

Wiping out drinking-associated memories could help those with alcohol problems to stay sober, suggests a study in rats.

As with other forms of addiction, environmental cues linked to drinking — such as the smell of beer — can trigger the urge to consume alcohol and increase the risk of a relapse into abuse. Over time, these learned associations can be maddeningly difficult to break.

How works a sugar addiction

Sugar seems to be evil on earth, everywhere we are flooded about how sugar is bad. In NYC, the administration wanted to forbid large size soda but the ban has been blocked by a judge.
Biosciencia's insight:

All you need to know about sugar and addiction, maybe the first step to limit it.

A Tumor With A Sweet Tooth: Innovative MRI Technique Uses Sugar To Track Cancer

A Tumor With A Sweet Tooth: Innovative MRI Technique Uses Sugar To Track Cancer | Biosciencia News | Scoop.it
Scientists at University College London use sugar to make cancer light up on magnetic resonance imaging (MRI) scanners.
Biosciencia's insight:

"We can detect cancer using the same sugar content found in half a standard sized chocolate bar," said senior author Professor Mark Lythgoe, the Director of Centre for Advanced Biomedical Imaging at University College London. His team's work was published today in Nature Medicine.

Scientists Use New Engineered Virus to Restore Sight | Medicine | Sci-News.com

Scientists Use New Engineered Virus to Restore Sight | Medicine | Sci-News.com | Biosciencia News | Scoop.it
Researchers have engineered a new adeno-associated virus that could greatly expand gene therapy to help restore sight to patients with blinding diseases.
Biosciencia's insight:

Over the last six years, several teams of scientists have successfully treated people with a rare inherited eye disease by injecting a virus with a normal gene directly into the retina of an eye with a defective gene.

Zinc: The perfect material for bioabsorbable stents?

Zinc: The perfect material for bioabsorbable stents? | Biosciencia News | Scoop.it
(Phys.org) —In 2012, more than 3 million people had stents inserted in their coronary arteries.
Biosciencia's insight:

Permanent stents are lifesavers, but they can also cause health problems when they are in the body for a long time. Michigan Tech researchers are investigating a new stent material, zinc, that would dissolve safely after the artery has healed.
