Scientists discover how plants disarm the toxic effects of excessive sunlight

...tional fossil fuels. "By understanding how biology solves this problem, we can fine-tune the design of these systems to minimize the harmful effects of singlet oxygen and enhance energy production." Reactive oxygen also plays an important role in human, animal and plant health, because it is often used as ...

Where bacteria get their genes

... member of UA's BIO5 Institute. The research also solves a long-standing evolutionary puzzle. Many scientists have argued that drawing traditional family trees does not make sense for bacteria, because their genomes represent a mix of genetic material from their parental cells and from other species of bac...

Human embryonic stem cells have the potential to develop into eggs and sperm in the laboratory

...logy today (Monday 20 June) that the research also solves the practical and ethical problems associated with obtaining human samples of primordial germ cells (PGCs), which are the ancestral cells that eventually form eggs and sperm (gametes). "Investigating the mechanisms of human primordial germ cell and g...

Study shows how retinoic acid enters a cell's nucleus

...many other proteins that don't have an NLS, and it solves a mystery that has been in the literature for a long time," Noy says. "It explains a basic mechanism of how this protein, CRABP-II, gets into the nucleus, where it can act to suppress tumors." CRABP-II is a member of a group of proteins called intra...

Scientists closer to new cancer detection method

...om the other molecules," Tan said. "This technique solves the problem caused by background signals from both the probe and the biological fluids where the proteins reside. We have engineered a molecular switch that turns on the fluorescence." The probe's green fluorescent burst lasts little more than a bil...

'Smart' nanoprobes light up disease

...nd to their molecular targets." Rice's technology solves this longstanding problem by using emissive nanoparticles called quantum dots that give off light in the near-infrared (NIR), a rare portion of the spectrum that has no background component in biomedical imaging. Near-infrared light also passes harml...

Normal chromosome ends elicit a limited DNA damage response

...protect the integrity of chromosomes. This finding solves for the first time an important question that has long puzzled scientists. The natural ends of chromosomes look just like broken strands of DNA that a cell's repair machinery is designed to fix. But mending chromosome ends, or telomeres, would set t...

Ancient humans brought bottle gourds to the Americas from Asia

...gical sites in the Western Hemisphere. The finding solves a longstanding archaeological enigma by explaining how a domesticated variant of a species native to Africa ended up millennia ago in places as far removed as modern-day Florida, Kentucky, Mexico and Peru. The work, by a team of anthropologists and ...

Mining for gems in the fungal genome

... The method developed by Keller and her colleagues solves this problem and promises to broaden the search for medically useful agents by taking a powerful, genome-wide approach. Their technique is called "genomic mining" because of its robust ability to dig through an entire fungal genome to locate nearly ...

Ancient DNA provides clues to the evolution of social behavior

...the colonial tuco-tuco's diversity got so low only solves part of the mystery. ''The really curious thing is how the species managed to persist for around 3,000 years with almost no genetic variation,'' Hadly says. ''Genetic variation is the toolkit for dealing with whatever the environment has to throw at ...

Tool developed to silence genes in specific tissues using RNAi

... D. Anderson team has come up with a solution that solves both problems. The technique they developed invol...t the potential of this approach, and hope that is solves what had become a significant roadblock to effective use of RNAi," he says. ...

Buckyballs boost antibody's chemotherapy payload

...ng for the buck." "The use of these nanomaterials solves some intractable problems in targeted therapy and additionally demonstrates the increasing value of the team science approach bridging different disciplines to uniquely address existing problems," Rosenblum said. ...

Gene linked to rare disease activates fat breakdown

...n down in adipose and other tissues." The finding solves a puzzle first raised in 2001 with the discovery that CGI-58 caused the lipid storage disease CDS in some patients, Zechner said. The symptoms characteristic of the disorder coupled with the structure of the enzyme encoded by CGI-58 led researchers t...

Copying nature could save us energy, study shows

...understanding the way in which biology defines and solves technical problems, we can develop new approaches ... cent similarity in the way biology and technology solves the problems they are faced with. "Whilst we have been quick to see the potential for developing ne...

Gene therapy research switches off joint inflammation; switches on genetic process of joint repair

...process glucosamine cannot be effective.1 So this solves a riddle that has plagued researchers for decades and corrects a problem that is exacerbated with aging. Multi-center, Randomized controlled Clinical Trial Underway Dr. Mark J.S. Miller said that, "This trial is important because it directly co...
