Immortal worms defy aging

February 29, 2012

Planarian flatworm

Researchers from The University of Nottingham have discovered how planarian flatworms overcome the aging process to be potentially immortal: they can rejuvenate their telomeres.

The discovery, funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and Medical Research Council (MRC), may eventually lead to alleviating aging and age-related characteristics in human cells.

Planarian worms have amazed scientists with their apparently limitless ability to regenerate. Researchers have… read more

Researcher Dr. Jeroen de Vries from the University of Twente MESA+ Institute for Nanotechnology suggests we could store data for one million to one billion years, using a new storage medium based on tungsten and graphene oxide.

He imagines two possible scenarios:

  • Disaster has devastated the earth and society must rebuild the world
  • We need to create a legacy for

How terahertz laser scanners will spy on you in airports

July 12, 2012

Genia

Genia Photonics has developed a programmable picosecond laser that is capable of spotting trace amounts of a variety of substances, including explosives, chemical agents, and hazardous biological substances at up to 50 meters.

It’s basically a spectrometer for radiation in the terahertz band. The beam used by Genia’s spectrometer is capable of penetrating most materials including wood, leather, cloth, ceramics, plastic, and paper, and can essentially… read more

Human muscle, regrown on animal scaffolding

September 17, 2012

Sergeant Strang has grown new leg muscle thanks to a thin sheet of material from a pig, The New York Times reports.

The material, called extracellular matrix, is the natural scaffolding that underlies all tissues and organs, in people as well as animals. It is produced by cells, and for years scientists thought that its main role was to hold them in their proper position.

But… read more

Fukushima fuel pool is urgent national security issue for America, ‘top threat facing humanity’

May 7, 2012

Fukushima

After visiting Fukushima, Senator Ron Wyden warned that the situation was worse than reported, Washington’s Blog reports … and urged Japan to accept international help to stabilize dangerous spent fuel pools.

Wyden said that the spent fuel is a national security threat to the U.S.: “The radiation caused by the failure of the spent fuel pools in the event of another earthquake could reach the West… read more

Easing brain fatigue with a walk in the park

An innovative new study from Scotland confirms the observation that you can ease brain fatigue simply by strolling through a leafy park, The New York Times reports.

Researchers have long theorized that green spaces are calming, requiring less of our so-called directed mental attention than busy, urban streets do, but it had not been possible to study the brains of people while they were actually outside, moving… read more

Assembling big structures out of small ultralight pieces

"Can you 3-D print an airplane?" question leads to major design breakthrough
August 19, 2013

MIT researchers have developed a lightweight structure whose tiny blocks can be snapped together much like the bricks of a child’s construction toy.

The new material, the researchers say, could revolutionize the assembly of airplanes, spacecraft, and even larger structures, such as dikes and levees.

The new approach to construction is described in a paper appearing in the journal Science, co-authored by postdoc Kenneth Cheung and… read more

The future of cryonics debate between physicist Michio Kaku and Alcor CEO Max More

December 22, 2013

ALCOR2

In response to a question, “What are the practical applications of cryogenics today, and what potential improvements can we expect 20 to 30 years down the line?” Michio Kaku, PhD, replied with a critique.

Max More, PhD, CEO of Alcor Life Extension Foundation, offered this response, noting that cryonics is “affordable by regular people. Ice does not form inside cells… read more

A computerized house that generates as much energy as it uses

NIST unveils net-zero energy residential test facility to improve testing of energy-efficient technologies
September 18, 2012

NIST Net Zero Energy Residential Test Facility

The U.S. Commerce Department’s National Institute of Standards and Technology (NIST) has unveiled a laboratory in the form of a typical suburban home, designed to demonstrate that a family of four can generate as much energy as it uses in a year.

The two-story, four-bedroom, three-bath “Net-Zero Energy Residential Test Facility“ was built to U.S. Green Building Council LEED Platinum standards — the highest standard for sustainable… read more

Macaque monkeys have the anatomy for human speech, so why can’t they speak?

December 14, 2016

macaque

While they have a speech-ready vocal tract, primates can’t speak because they lack a speech-ready brain, contrary to widespread opinion that they are limited by anatomy, researchers at Princeton University and associates have reported Dec. 9 in the open-access journal Science Advances.

The researchers reached this conclusion by first recording X-ray videos showing the movements of the different parts of a macaque’s vocal anatomy — such as the tongue,… read more

Are you ready for mood-altering drugs precisely inserted into your brain?

June 24, 2016

PFC-directed oscillatory interactions ft

Imagine if doctors could precisely insert a tiny amount of a custom drug into a specific circuit in your brain and improve your depression (or other mood problems) — instead of treating the entire brain.

That’s exactly what Duke University researchers have explored in mice. Stress-susceptible animals that appeared depressed or anxious were restored to relatively normal behavior this way, according to a study appearing in the… read more

Harvard scientists have created a type of “cyborg” tissue for the first time by embedding a three-dimensional network of functional, biocompatible, nanoscale wires into engineered human tissues.

The research team led by Charles M. Lieber, the Mark Hyman Jr. Professor of Chemistry at Harvard, and Daniel Kohane, a Harvard Medical School professor in the Departmentread more

More-efficient solar-powered steam

Can convert 85 percent of incoming solar energy into steam, eliminating need for complex, costly systems to highly concentrate sunlight
July 22, 2014

solar steam generator - ft

A new carbon-based material structure developed at MIT generates steam from solar energy.

The structure — a layer of graphite flakes and an underlying carbon foam — is a porous, insulating material structure that floats on water.

When sunlight hits the structure’s surface, it creates a hotspot in the graphite, drawing water up through the material’s pores, where it evaporates as steam. The brighter the light,… read more

DHS to test unmanned aircraft for variety of applications.

The U.S. Department of Homeland Security this week issued a call for unmanned systems makers to participate in a program that will ultimately determine their safety and performance for use in first responder, law enforcement and border security situations, Network World Layer 8 reports.

In a twist that will certainly raise some eyebrows,  the program’s results  of… read more
