In only 10 percent of flowering plant species do female and male flowers exist on separate plants, where they typically remain female or male throughout their lifetime. The other 90 percent combine both sexes in one plant.

The "loser effect"- avoiding violence after losing a fight - evolves independently of any change in fighting ability, according to results after scientists studied male broad-horned flour beetles, which regularly fight over females, to see how long they avoided fights after a defeat. 

Most would not start a fight for about four days after a loss, but researchers selectively bred the beetles for a shorter duration of this loser effect and found that it evolved to be shorter - despite no improvement in fighting prowess. 

A Neptunian planet named NGTS-4b has been found in what should be a 'Neptunian Desert' using the Next-Generation Transit Survey (NGTS) observing facility, designed to search for transiting planets on bright stars. NGTS-4b is so small other ground surveys wouldn't have spotted it.

But small is relative. Though NGTS-4b is 20% smaller than Neptune, that is about 3 times the size of Earth, and 20 times our Earth in mass. It has been nicknamed the 'Forbidden' planet by researchers and is hotter than Mercury at 1,000 degrees Celsius. It orbits around the star in only 1.3 days - the equivalent of Earth's orbit around the sun of one year. 

Palm oil is being blamed for a lot but two academic conservationists note that those who ask to boycott all palm oil due to its contribution to deforestation should also consider boycotting coffee, chocolate and coconut if they wish to be consistent.

Are you against or really against palm oil? 

Ask anyone who has followed any environmental news related to palm oil if they are for or against it and they will most likely say 'Against.' They'll mention destroyed orangutan habitats and rainforests disappearing.

Evolution will happen, in medicines like antibiotics, and in crop protection like herbicides. Though some groups may continue to use older, less effective products such as organic copper sulfate, evidence-based agriculture works to create new products that do less environmental damage, such as neonicotinoids.

Were dinosaurs green? You'd think so going by pop culture imagery but there is no way to know if they were green or grey or something else.
