and then compared the forces of their jumps. The largemouth bass uses a common jumping technique to return to the water
whereby it flips its head over its body towards the tail end to jump away from a stimulus. The researchers found striking differences in these fish's jumping forces:
the bass generates forces mostly in the vertical direction which means that it basically just goes up without moving sideways;
the mangrove rivulus generates the greatest forces in the antero-posterior (front-back) and medio-lateral (side-to-side) dimensions

The findings could advance the search for a new fundamental force in nature that could explain why the Big bang created more matter than antimatter--a pivotal imbalance in the history of everything.
The Standard model describes four fundamental forces or interactions that govern how matter behaves: Gravity attracts massive bodies to one another.
The electromagnetic interaction gives rise to forces on electrically charged bodies. And the strong and weak forces operate in the cores of atoms binding together neutrons and protons or causing those particles to decay.
Physicists have been searching for signs of a new force or interaction that might explain the matter-antimatter discrepancy.

#Power struggles are kept best out of the public eye: Audiences influence future status of quails following fights between rivalsfor animals prevailing in a fight affects their likelihood of winning future conflicts.
The opposite is true of losing a fight. The sex hormone testosterone is believed often to mediate this winner effect.
Researchers from the Max Planck Institute for Ornithology in Seewiesen have examined whether the presence of an audience influences the behaviour and the testosterone changes of Japanese quails (Coturnix japonica) after a fight.
The evidence shows that both winners and losers exhibit raised testosterone levels after a conflict without an audience.
Furthermore both winners and losers are able to maintain their social status within their group. With an audience on the other hand this remained true for winners
Battles for territory and mating partners are widespread in the animal world and are fought usually by males.
The concentration of this substance often rises dramatically during a fight. However the social environment in which the rivals fight their battle can change the context
and affect the role of testosterone for maintaining dominance. Experience plays a role for instance how often the opponents got involved in a conflict
and whether they have met before. Of crucial importance can also be whether the fight is watched by spectators.
Audiences can have a decisive effect on the outcome of a contest between humans too.
With support of the Alexander-Von-humboldt Society scientists working with Katharina Hirschenhauser from the Max Planck Institute for Ornithology in Seewiesen have been studying the influence of mixed-sex audiences on future social status after a fight.
The scientists observed fights between two dominant male quails in a central arena. The members of the respective social group either were allowed to watch the fight or not.
During the fighting phase which lasted an average of seven minutes the eventual winners attacked their rivals 29 times on average.
Although the fights are naturally pretty rough none of the combatants got seriously injured. The winners without exception retained their dominant status (the winner effect.
however even the losers were able to maintain their dominant status. As expected testosterone levels were raised after the fight
After a fight in front of an audience though the losers had lower testosterone levels. The winners on the other hand showed a similar increase to quails that had fought without an audience.
In order to determine whether a change in status after losing a fight in front of an audience could be prevented physiologically the scientists treated the losers immediately after the fight with a testosterone cream on the skin.
They injected the winners with a testosterone blocker directly after the fight and observed their behaviour in the social group.
Apparently the information about a fight essentially determines the loser's future status in its group.

Relationships between humans and wolves are linked often to conflicts with livestock breeding activities. Contrary to a widespread belief among western environmentalists these conflicts don't only occur only in western countries
even though their intensity often appears lower in other places. Indeed in many countries livestock breeding activities have been dealing with wolves for centuries
Now they are perceived more as a threat to the Kyrgyz's main capital in times of crisis
In this context wolves are perceived not as the main threat to their future but as an additional threat
and to an increase in the perception of conflicts even in countries where humans and wolves have coexisted continuously.
