Paraplegic rats walk and regain feeling after stem cell treatment

Paralyzed rats implanted with engineered tissue containing human stem cells were able to walk independently and regained sensory perception in their hind legs and tail. The implanted rats also show some degree of healing in their spinal cords. The research de

Ceria nanoparticles: It is the surface that matters

Exhaust gas cleaning of passenger cars, power generation from sunlight, or water splitting: In the future, these and other applications may profit from new findings relating to ceria. Scientists have studied ceria nanoparticles with the help of probe molecule

New treasures from Tutankhamun’s tomb

Archaeologists have examined embossed gold applications from the sensational find of 1922. The motifs indicate surprising links between the Levant and the Egypt of the pharaohs.

New procedures for DNA stability

In eukaryotic cells the proximity of the genes to the nuclear pores, which are found in the nuclear membrane, contributes to maintaining the integrity of the genome. This is due to the fact that the anchoring of DNA to the pore during transcription avoids th

Uninsured heart attack, stroke patients face ‘catastrophic’ costs

Heart attack and stroke patients without medical insurance face “devastating” health care costs that can bankrupt them, research shows.

New dye gives scientists a clearer insight into the brain

Researchers have designed a new dye that can be used to observe the electrical activity of neurons in the brain and could lead to finding a new and more efficient way of treating neurological diseases.

What is the computational power of the universe?

Can a close look at the universe give us solutions to problems too difficult for a computer -- even if we built a computer larger than a planet? Physicist Stephen Jordan reflects on this question in a new NIST video, along with a scientific paper that conside

Study urges global-change researchers to embrace variability

A new review article presents evidence that argues for a more nuanced approach to the design of global-change experiments -- one that acknowledges and purposefully incorporates the variability inherent in nature.

Why these Amish live longer and healthier: An internal ‘Fountain of Youth’

The first genetic mutation that appears to protect against multiple aspects of biological aging in humans has been discovered in an extended family of Old Order Amish living in the vicinity of Berne, Indiana, report scientists. An experimental “longevity

Cell-based therapy for type 1 diabetes?

Type 1 diabetes has been successfully reveresed in a mouse model by infusing blood stem cells pre-treated to produce more of a protein called PD-L1, which is deficient in mice (and people) with type 1 diabetes. The cells curbed the autoimmune reaction in cell

Microbial ecosystem at Laguna La Brava may contain novel microorganisms

An investigation of the microbial environment at Laguna La Brava in Chile may suggest that novel microorganisms might be at work in the absence of cyanobacteria, according to a new study.

A delicate crossing: Controller developed to open the blood-brain barrier with precision

Researchers are investigating a way to temporarily loosen the blood-brain barrier to deliver drugs with the assistance of microbubbles. In a new advancement, they have developed a system in preclinical models that offers a finer degree of control - and, there

Genome of wheat ancestor sequenced

Sequencing the bread wheat genome has long been considered an almost insurmountable task, due to its enormous size and complexity. Now, scientists have come a step closer to solving the puzzle by sequencing the genome of a wild ancestor of bread wheat known a

Gut microbes can protect against high blood pressure

Microbes living in your gut can help protect against the effects of a high-salt diet, according to a new study.

Potential mediator for social memory formation
