Rejuvenating blood by reprogramming stem cells

March 27, 2013

Humanbood600x

Lund University researchers have succeeded in rejuvenating the blood of mice by reversing, or reprogramming, the stem cells that produce blood.

Stem cells form the origin of all the cells in the body and can divide an unlimited number of times. When stem cells divide, one cell remains a stem cell and the other matures into the type of cell needed by the body, for example a blood… read more

Jarno Smeets, famous for his HumanBirdWings project, may just have made semi-self-propelled aeronautical history, flying over 100 meters on his self-built wings. His inspiration: the albatross.

UPDATE: The ‘birdman’ is FAKE

Inventor Dean Kamen is planning a 2.5 kW home version of his Deka Research Beacon 10 Stirling engine that could provide efficient around-the-clock power or hot water to a home or business, reports Forbes.

Kamen says the current Beacon is intended for businesses like laundries or restaurants that use a lot of hot water. “With commercialization partner NRG Energy, he’s deployed… read more

Sandia nuclear-fusion liners break even in tests

September 19, 2012

Ryan_McBride

Magnetically imploded tubes called liners, intended to help produce controlled nuclear fusion at scientific “break-even” energies or better within the next few years, have functioned successfully in preliminary tests, according to a Sandia research paper accepted for publication by Physical Review Letters (PRL).

To exceed scientific break-even is the most hotly sought-after goal of fusion research, in which the energy released by a fusion reaction is… read more

Government lab reveals it has operated quantum internet for over two years

QC_network

A quantum internet capable of sending perfectly secure messages has been running at Los Alamos National Labs for the last two and a half years, MIT Technology Review reports.

One of the dreams for security experts is the creation of a quantum internet using quantum cryptography that allows perfectly secure communication based on the powerful laws of quantum mechanics.

The researchers created a quantum network based around… read more

DARPA seeks 2000 percent increase in robot power transmission efficiency

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

cells to food

In a paper in the Cell Press journal Trends in Biotechnology, Cor van der Weele of Wageningen University in The Netherlands and coauthor Johannes Tramper describe a potential meat manufacturing process, starting with a vial of cells taken from a cell bank and ending with a pressed cake of minced meat.

Cor van der Weele  point out that the rising demand for meat around the world is… read more

Woman dies from antibiotic-resistant bacteria when no antibiotics worked

Deadly “CRE” family of superbug bacteria spreading more widely and stealthily, Harvard study finds
January 18, 2017

CRE bacteria

The death of a hospitalized patient in Reno Nevada for whom no available antibiotics worked highlights what World Health Organization and other public-health experts have been warning: antibiotic resistance is a serious threat and has gone global.

The patient — a female in her 70s — was admitted in for an infection and died in September 2016 from septic shock the CDC announced on Jan.… read more

An agile humanoid robot

NimbRo-OP_5_900

University of Bonn computer scientists have developed a scoccer-playing robot called NimbRo-OP intended to develop new capabilities for humanoid bipedal robots, such as using tools, climbing stairs, and using human facial expressions, gestures and body language for communicating.

With 20 drive elements that convert computer commands into mechanical motions, NimbRo-OP is highly agile. For example, it can kick a soccer ball, and get… read more

Nanostructured ‘sandwich’ boosts solar-cell efficiency almost three times

December 10, 2012

Princeton researchers have found a simple and economical way to nearly triple the efficiency of organic solar cells, the cheap and flexible plastic devices that many scientists believe could be the future of solar power.

The researchers, led by electrical engineer Stephen Chou, the Joseph C. Elgin Professor of Engineering, were able to increase the efficiency of the solar cells 175 percent by using… read more

An automated ‘time machine’ to reconstruct ancient languages

Researchers from University of California, Berkeley and the University of British Columbia have created a computer program that can rapidly reconstruct “proto-languages” — the linguistic ancestors from which all modern languages have evolved.

These earliest-known languages include Proto-Indo-European, Proto-Afroasiatic and, in this case, Proto-Austronesian, which gave rise to languages spoken in Southeast Asia, parts of continental Asia, Australasia and the Pacific.

Ancient languages hold… read more

A 50 gigapixel camera five times better than 20/20 human vision

June 21, 2012

gigapixel_camera

By synchronizing 98 tiny cameras in a single device, engineers from Duke University and the University of Arizona have created a prototype camera that could capture up to 50 gigapixels of data (50,000 megapixels) and images with unprecedented detail.

The AWARE-2 camera’s resolution is five times better than 20/20 human vision over a 120 degree horizontal field.

By comparison, most consumer cameras are capable of taking photographs with sizes ranging… read more

Researchers from the University of Bonn and the Central Institute of Mental Health in Mannheim found that “pro­blematic” Internet users, especially women, are more often carriers of a variation in the CHRNA4 gene, the nicotinic acetylcholine receptor gene, which that also plays a major role in nicotine addiction and generation of dopamine.

The T- variant (CC genotype) of the rs1044396 polymorphism on the CHRNA4 gene occurred significantly more frequently*, the… read more
