You are the company you keep—A new screening method detects direct biomolecule interactions
Posted by Xavier Rosseel in categories: biotech/medical, genetics, health
Proteins are the building blocks of the cell. They do most of the work and are essential for the structure, function and dynamic regulation of the cell and body’s tissues and organs. Proteins rarely work alone, they interact, form protein complexes or bind DNA and RNA to control what a cell does. These complexes are key pieces of many important reactions within the cell, such as energy metabolism or gene regulation. Any change in those interactions, which can for example be caused by a mutation, can make the difference between health and disease. Hence, for understanding how cells operate, or what might go wrong in ill cells, it is essential to know how their building blocks interact.
New technologies allowed scientists during the last decades to understand the genetic information an organism possess, which of this information is actively used and which proteins are made by the cell in different circumstances. Now it is a big challenge to understand how biomolecules such as proteins and RNA messenger molecules combine to form the complexes required for a functional cell. In other words, we know the ten thousands of parts a cell is build off, but we don’t know how they belong together.
In a paper published in Nature Communications, scientists at the Centre for Genomic Regulation (CRG) describe the development of a new method, named “rec-YnH”, which was designed to understand the complexes formed between hundreds of proteins and RNAs at the same time.

MIT punches out cell-sized robots made of graphene
Posted by Klaus Baldauf in categories: health, robotics/AI
Robots are getting smaller and smaller, from the size of bugs down to tiny bead-shaped robots that could one day swim through the body to monitor health or deliver medication. MIT engineers recently managed to create cell-sized robots that could collect data about their environment, but were a little tricky to manufacture. Now, the team has found a way to mass produce these synthetic cells (syncells) through controlled fracturing of graphene.

Air pollution leads to millions of ER visits for asthma attacks worldwide
Posted by Xavier Rosseel in categories: health, sustainability, transportation
The new research suggests that:
WASHINGTON, DC (Oct. 24, 2018)— Nine to 33 million visits to the emergency room (ER) for asthma worldwide may be triggered by breathing in air polluted by ozone or fine particulate matter—pollutants that can enter the lung’s deep airways, according to a study published today.
Scientists have long known that breathing in air sullied by car emissions and other pollutants could trigger asthma attacks. However, the new study is the first to quantify air pollution’s impact on asthma cases around the globe.

Biohackers Are Implanting Everything From Magnets to Sex Toys

Biohacking raises a host of ethical issues, particularly about data protection and cybersecurity as virtually every tech gadget risks being hacked or manipulated. And implants can even become cyberweapons, with the potential to send malicious links to others. “You can switch off and put away an infected smartphone, but you can’t do that with an implant,” says Friedemann Ebelt, an activist with Digitalcourage, a German data privacy and internet rights group.
Patrick Kramer sticks a needle into a customer’s hand and injects a microchip the size of a grain of rice under the skin. “You’re now a cyborg,” he says after plastering a Band-Aid on the small wound between Guilherme Geronimo’s thumb and index finger. The 34-year-old Brazilian plans to use the chip, similar to those implanted in millions of cats, dogs, and livestock, to unlock doors and store a digital business card.
Kramer is chief executive officer of Digiwell, a Hamburg startup in what aficionados call body hacking—digital technology inserted into people. Kramer says he’s implanted about 2,000 such chips in the past 18 months, and he has three in his own hands: to open his office door, store medical data, and share his contact information. Digiwell is one of a handful of companies offering similar services, and biohacking advocates estimate there are about 100,000 cyborgs worldwide. “The question isn’t ‘Do you have a microchip?’ ” Kramer says. “It’s more like, ‘How many?’ We’ve entered the mainstream.”
