SAN FRANCISCO – A planet made of diamonds may sound lovely, but you wouldn’t want to live there.
A new study suggests that some stars in the Milky Way could harbor “carbon super-Earths” – giant terrestrial planets that contain up to 50 percent diamond.
But if they exist, those planets are likely devoid of life as we know it. (more…)
*Bacterial cells have gene mutations that allow them to ‘stick’ to the devices*
New research suggests that some patients develop a potentially deadly blood infection from their implanted cardiac devices because bacterial cells in their bodies have gene mutations that allow them to stick to the devices.
Geoscientists were the major contributors to the finding.
Proceedings of the National Academy of Sciences published the study results online this week. (more…)
COLUMBUS, Ohio – For the first time, researchers have found a way to inject a precise dose of a gene therapy agent directly into a single living cell without a needle.
The technique uses electricity to “shoot” bits of therapeutic biomolecules through a tiny channel and into a cell in a fraction of a second.
L. James Lee and his colleagues at Ohio State University describe the technique in the online edition of the journal Nature Nanotechnology, where they report successfully inserting specific doses of an anti-cancer gene into individual leukemia cells to kill them. (more…)
COLUMBUS, Ohio – A new study reveals how the delay computer users sometimes experience when making video calls over the internet can actually help communication in some circumstances, even though it is frustrating in many others.
Researchers found that when two strangers first talked about an emotionally charged topic over a video connection with a one-second delay, they actually reported less frustration than did those who talked with no delay. (more…)
COLUMBUS, Ohio – Both marriage and divorce can act as “weight shocks,” leading people to add a few extra pounds – especially among those over age 30 – according to a new study.
But when it comes to large weight gains, the effects of marital transitions are quite different for men than they are for women.
For men, the risk of a large weight gain increased most prominently after a divorce. But for women, the risk of a large weight gain was most likely after marriage. (more…)
COLUMBUS, Ohio – Think about how much you fight and argue with your spouse today. A new study suggests that your current level of conflict probably won’t change much for the remainder of your marriage.
That may be good news for the 16 percent of couples who report little conflict or even the 60 percent who have only moderate levels of conflict. But it’s not such happy news for the 22 percent of couples who say they fight and argue with each other a lot.
The study followed nearly 1,000 couples over 20 years, from 1980 to 2000. (more…)
COLUMBUS, Ohio – A new study uses – for the first time – recorded jailhouse telephone conversations between men charged with felony domestic violence and their victims to help reveal why some victims decide not to follow through on the charges.
Researchers listened to telephone conversations between 17 accused male abusers in a Washington state detention facility and their female victims, all of whom decided to withdraw their accusations of abuse. For each of the couples, the researchers analyzed up to about three hours of phone conversations. (more…)
COLUMBUS, Ohio – Salmonella cells have hijacked the protein-building process to maintain their ability to cause illness, new research suggests.
Scientists say that these bacteria have modified what has long been considered typical cell behavior by using a beta form of an amino acid – as opposed to an alpha form – during the act of making proteins. (more…)
