Climate change: Current warming 'unparalleled' in 2,000 years

The speed and extent of current global warming exceeds any similar event in the past 2,000 years, researchers say.

They show that famous historic events like the "Little Ice Age" don't compare with the scale of warming seen over the last century.

The research suggests that the current warming rate is higher than any observed previously.

The scientists say it shows many of the arguments used by climate sceptics are no longer valid.

The Green Treasure

basil is considered a green treasure that is almost present in every house. In this report, there are many benefits of this plant that must be brought in every room of your home.

In addition to its good taste in dishes, it is a cure for mosquito bites, especially if the skin is rubbed with a few leaves before bedtime. It is also recommended to keep a small plant sprout in the room where you sleep because the smell of the aroma is a sedative and mosquito repellent.

As well its effectiveness in fighting viral, bacterial and fungal infections, it protects the respiratory system from many dangers, including chronic or acute bronchitis, because it contains essential oils ingredients.

It is useful to eliminate phlegm and facilitate the breathing process, because plant nutrients, essential oils and other minerals increase the resistance to asthma.

The preservative contains vitamin C and other antioxidants that protect the heart from the effects of free radicals in addition to the lower levels of cholesterol in the blood.

How mammals' brains evolved to distinguish odors is nothing to sniff at

The world is filled with millions upon millions of distinct smells, but how mammals' brains evolved to tell them apart is something of a mystery.

Now, two neuroscientists from the Salk Institute and UC San Diego have discovered that at least six types of mammals -- from mice to cats -- distinguish odors in roughly the same way, using circuitry in the brain that's evolutionarily preserved across species, according to Science Daily.

"The study yields insights into organizational principles underpinning brain circuitry for olfaction in mammals that may be applied to other parts of the brain and other species," says Charles Stevens, distinguished professor emeritus in Salk's Neurobiology Laboratory and coauthor of the research.

Do these baby baboons undermine trendy gender-neutral theories about toys?

The gender-neutral toys movement may have been thwarted by a group of baboons after a new BBC documentary showed females playing with dolls and males playing with trucks.

An interest in gender-neutral toys has been steadily on the rise for years amid fears of reinforcing a societal male-female divide, according to Daily Mail.

But a new BBC 2 documentary, Animals at Play, has revealed how differently the minds of the genders work, at least in baboons.

Scientists discover how plants breathe -- and how humans shaped their 'lungs'

Scientists have discovered how plants create networks of air channels -- the lungs of the leaf -- to transport carbon dioxide (CO2) to their cells.

Botanists have known since the 19th century that leaves have pores -- called stomata -- and contain an intricate internal network of air channels. But until now it wasn't understood how those channels form in the right places in order to provide a steady flow of CO2 to every plant cell, according to Science Daily.

The new study, led by scientists at the University of Sheffield's Institute for Sustainable Food used genetic manipulation techniques to reveal that the more stomata a leaf has, the more airspace it forms.
