John Markoff reports in the New York Times about scientists who created online video game EteRNA in which players can come up with novel ways of folding RNA. The scientists claim it is “democratizing science” by attracting thousands of citizens to participate in constructing new ways to understand and use the folding of RNA.
Finally, the NYT reports about wine. While archaeologists discovered the earliest winemaking facility of the world in Armenia where wine was being made there as early as 7,400 years ago – proving that mankind must have found something positive in consuming red wine, today’s scientists still grapple at understanding the benefits. Dealing with the halt of the last resveratrol trial in which biotech company Sirtis (now GSK) tried to prove that this particular ingredient of red wine is able to extend the life span of obese Rhesus Monkeys, Nicholas Wade casts doubt about the usefulness of resveratrol and resveratrol-mimicking chemicals as anti-aging drugs.
The Economist this week deals with epigenetics in a story featuring that not only mothers but fathers as well may be able to pass on a propensity to obesity if they themselves have been starved during their life before fathering offspring. The findings are from mice.
Djuke Veldhuis reports in New Scientist about a simple blood test for Down’s syndrome that successfully detected all 86 cases confirmed by other methods. The validation study is published in BMJ 2011; 342:c7401.
In The Scientist, Vanessa Schipani elaborates why it is not a good idea to use the usually well-fed, parasite-free and genetically similar lab animals to study immunology. Instead, she makes a case for ecoimmunology, a new field studying immunology in wild animals and still trying to attract more researchers and funding. Jef Akst reports about cancer researchers identifying an increasing number of proteins that have a dual nature in cancer: they may initially promote the development of tumors, but in the long run make them less aggressive, or vice versa. “One problem in identifying such two-faced proteins may stem from the fact that these opposing effects are rarely demonstrated in the same research paper,” Jef writes, adding that both reviewers and funding agencies do not like this kind of complex stories and rather prefer focusing on one side of the coin.
Speaking of peer reviews, Martina Lenzen-Schulte in the German Frankfurter Allgemeine Zeitung (FAZ) reports about efforts of peer-reviewed journals like the British Medical Journal or the EMBO Journal to make the peer review process more transparent by disclosing the names of the reviewers and the review or even the complete review process. Goals are to improve the quality of the process and of reviews in general and to prevent reviewers from either stealing ideas or putting a spoke in competitors’ wheels.
Volker Stollorz in Frankfurter Allgemeine Sonntagszeitung (FAS) provides a concise review of the ongoing debate whether the chronic fatigue syndrome (CFS) is caused by the newly discovered retrovirus XMRV or whether contamination of specimens, the lab or chemicals used in experiments have produce results that could be mistaken for XMRV. The article clarifies that there are increasing doubts about the hypothesis as many independent researchers have not been able to find the virus in the blood of CFS patients and/or from blood banks.
Focus reports on new efforts to combat AIDS by learning from the about 1% of humans resistant to the virus. The article cites James Hoxie, of Penn Center for AIDS Research, who is trying to cure AIDS by removing from immune cells of AIDS patients those genes that provide entry to HIV. Subsequently, the immune cells are transferred back to the patient. Focus states the approach goes back to findings in Germany at Charité Berlin where a patient suffering from both AIDS and leukemia received a bone marrow transplant from a HIV resistant donor. Citing an article in Blood (DOI 10.1182/blood-2010-09-309591), Focus states the patient is now virus-free and off AIDS medications.
