Brain imaging reveals neural roots of caring

Thu, 08/06/2017 - 4:36pm
When others suffer, we humans empathize. Our feelings of empathy take different forms, such as distress when we imagine and internalize someone's pain and compassion as we sympathize with their condition. These different feelings involve distinct patterns of brain activity, according to a study. Feelings of empathy may seem subtle and personal, but this study found that the brain patterns associated with these feelings are consistent and predictable across individuals.

Extinct early whales listened like their relatives on land, fossil evidence shows

Thu, 08/06/2017 - 4:36pm
Whales show surprisingly vast differences in hearing ability. Baleen whales tune into infrasonic sounds to communicate over long distances. Toothed whales do just the opposite, relying on ultrasonic frequencies too high for humans to hear. Now researchers have fossil evidence from extinct early whale species to suggest that those differences in hearing arose only after whales evolved into the fully aquatic animals we know today.

Researchers uncover new instruction manual to repair broken DNA

Thu, 08/06/2017 - 4:36pm
Researchers have discovered how the Rad52 protein is a crucial player in RNA-dependent DNA repair. The results reveal an unexpected function of the homologous recombination protein Rad52 and may help to identify new therapeutic targets for cancer

Sensitivity to inequity is in wolves' and dogs' blood

Thu, 08/06/2017 - 4:36pm
Not only dogs but also wolves react to inequity -- similar to humans or primates, suggests new research. Wolves and dogs refused to cooperate in an experiment when only the partner got a treat or they themselves received a lower quality reward. The sensitivity to inequity is not likely to be an effect of domestication, as assumed so far. It is rather a behavior inherited from a common ancestor.

The mysterious bend in the Hawaiian-Emperor chain

Thu, 08/06/2017 - 4:36pm
The volcanic islands of Hawaii represent the youngest end of a 80 million years old and roughly 6,000 kilometers long mountain chain on the ground of the Pacific Ocean. The so-called Hawaiian-Emperor chain consisting of dozens of volcanoes is well known for its peculiar 60 degrees bend. The cause for this bend has been heavily debated for decades. Scientists now offer an explanation in a new study.

Cosmic inflation: Higgs says goodbye to his 'little brother'

Thu, 08/06/2017 - 4:36pm
In the first moments after the Big Bang, the Universe was able to expand even billions of billions of billions of times faster than today. Such rapid expansion should be due to a primordial force field, acting with a new particle: inflaton. From the latest analysis of the decay of mesons, carried out in the LHCb experiment by physicists from Cracow and Zurich, it appears, however, that the most probable light inflaton almost certainly does not exist.

Delayed food introduction increases risk of sensitization, study finds

Thu, 08/06/2017 - 4:35pm
Infants who avoided cow's milk products in their first year were nearly four times as likely to be sensitized to cow's milk compared to infants who consumed cow's milk products before 12 months of age, scientists discovered from sing data from more than 2,100 children. Similarly, infants who avoided egg or peanut in their first year were nearly twice as likely to be sensitized to those foods compared to infants who consumed them before 12 months of age.

Mind changing can be risky

Thu, 08/06/2017 - 1:06pm
When leaders use a moral argument rather than a pragmatic one as the basis for a position, they may be judged harshly if they change that position later. They are perceived as hypocrites, less effective and less worthy of future support, according to research.
