Why parents in their prime produce the best offspring: Research
Updated : 3 years, 4 months ago IST
Parents face a trade-off between putting resources into their offspring versus using resources to enhance their chances of survival so they can have more offspring. The best allocation of resources depends on age. More experienced parents are better at getting food, so they can pass on more

Bumblebees balance pain perception with pursuit of food
Updated : 3 years, 7 months ago IST
Bangalore (Karnataka) [India], July 27 (ANI): A new study discovered that bumblebees can modulate behavior to negotiate a trade-off between the perception of harmful stimuli and the pursuit of food. Mammals can modulate their responses to noxious stimuli, such that pain perception does not i

Study finds new signalling molecule that boosts brown fat cells' energy co
Updated : 3 years, 7 months ago IST
Bonn [Germany], July 20 (ANI): Fat cells often store energy. However, energy is lost as heat in brown fat cells; as a result, brown fat acts as a biological heater. This mechanism is consequently present in most mammals. In adults, brown fat activation is positively correlated with cardiomet
