Birds prepare for war just like humans

Birds get ready for battle just like humans do, new research has revealed. Researchers involved in the study found that birds try to boost the morale of their comrades before entering combat zones.

The study was conducted on green wood hoopoes, which live in family groups of up to 12 in the forests of South Africa. The birds, which feed on insects and termites, often fight with rival groups to take control of nesting sites and rich feeding grounds.

And the study has revealed a dramatic increase in preening occurs before they enter the borders of their territory ahead of combat. Dr Andy Radford, who conducted the study for the University of Bristol, believes the behaviour gives cowardly birds more courage in battle.

“We have analysed this preparatory behaviour in humans, but this is the first time we have looked for it in non-human animals,” said Radford.

Tart cherry juice may be natural cure for insomnia
A new research has suggested that drinking tart cherry juice daily can help reduce the severity of insomnia and time spent awake after going to sleep.

To reach the conclusion, a team of University of Pennsylvania, University of Rochester and VA Centre of Canandaigua researchers conducted a pilot study on the sleep habits of 15 older adults.

The adults drank 8 ounces of tart cherry juice beverage in the morning and evening for 2 weeks, and a comparable matched juice drink, with no tart cherry juice, for another 2 week period.

There were significant reductions in reported insomnia severity and the adults saved about 17 minutes of wake time after going to sleep, on average, when drinking cherry juice daily, compared to when they were drinking the juice drink.The researchers suspect tart cherries’ natural benefits could be due in part to their relatively high content of melatonin — a natural antioxidant in cherries with established ability to help moderate the body’s sleep-wake cycle.

Language may influence how you think about others
The language a person speaks may influence their thoughts, according to a new study.
Researchers Shai Danziger of Ben-Gurion University and Robert Ward of Bangor University conducted a study amongst Arab Israelis who speak both Arabic and Hebrew.
“It’s likely that a bilingual Arab Israeli will consider Arabs more positively in an Arab speaking environment than a Hebrew speaking environment,” says Danziger.
The study found that the student volunteers found it easier to associate Arab names with ‘good’ trait words and Jewish names with ‘bad’ trait words than Arab names with ‘bad’ trait words and Jewish names with ‘good’ trait words. In the Hebrew session, however, they showed less of a positive bias toward Arab names over Jewish names.
