New research shows just 1% of E. coli bacteria's genetic mutations are lethal.
Watching bacteria and viruses duke it out, evolving to outwit each other.

A core idea in molecular biology is that one gene codes for one protein. Now biologists have found an example of a gene that yields two forms of a protein – enabling it to evolve new functionality.

Some recent bad behaviour has been explained as being alpha but the scientist who coined the phrase discredits that theory. Instead, Prof. Sosteric suggests alphas are raised on toxic socialization.

Humans have long been trying differentiate themselves from the rest of the biological world. Is it because we're superior, or just insecure?
Emergency personnel at the Ashley Wood Recovery Centre in Salisbury as the investigation into the suspected nerve agent attack on Russian double agent Sergei Skripal continues.
An audio version of an in depth article on the story of how the nerve agent used in an attack on former Russian spy Sergei Skripal was developed.
Spider silk is a bit like a cross between steel and rubber.

Some spiders produce silk than can actually be stronger than steel and 50 times as light.
Flowers above, traps below.
Venus flytrap plants have 'traps' that snap shut on insect prey. But they also rely on insects for pollination. New research suggests how the plant avoids eating its allies.

Canada's female scientists are superstars in their fields yet most Canadians have never heard of them. On International Day for Women in Science, it's time to give them the recognition they deserve.
What goes in must come out.

Meet the brawny bug with a concoction so caustic it'll make a toad vomit.
The solution to the problem of campus safety lies in making students aware, individually and collectively, of the dangers of their heterosexual masculinity.
Sexual violence against women is not the result of a few odd bad elements. Sexual violence is part and parcel of heterosexual masculinity.
At just 18 months old, young children can show biological evidence of added stress.
At less than 2 years old, children of mothers with increasing depressive symptoms can show signs of added stress and quicker cellular aging.
Super-black feathers on these guys are like looking into a dark cave.
Male Birds of Paradise have patches of super-black plumage that absorb 99.95 percent of light. New research identified their feathers' microscopic structures that make them look so very dark.

Rey (Daisy Ridley), in
Star Wars: The Last Jedi, ponders the light and dark sides of the Force.
Star Wars: The Last Jedi leaves many questions about the saga in a galaxy far, far away unanswered. Fortunately, biology may offer a insights on the Force, midi-chlorians, clones, and Rey's lineage.
Delivering genetic material is a key challenge in gene therapy.

One big challenge for gene therapies is delivering DNA or RNA safely to cells inside patients' bodies. New nanoparticles could be an improvement over the current standard – repurposed viruses.
Modern advances come with new liabilities.
Biologists' growing reliance on computers advances the field – but comes with new risks. The first step toward improved cyberbiosecurity is increasing awareness of possible threats.
Though not this obvious from the outside, plants are keeping time.
Precisely calibrated timekeepers are found in organisms from all domains of life. Biologists are studying how they influence plant/pathogen interactions – what they learn could lead to human medicines.

Lynn Margulis (1938-2011) was a courageous scholar whose remarkable work on the role of symbiosis in evolution stands as a magisterial contribution of science.
Is this how we got the sperm and the egg?
An ancient sexual conflict over mitochondrial inheritance may be responsible for the evolution of the two sexes as we know them.
Worms do have something in their mouth that they can poke out, like a tongue. It is called a stylet.
The short answer is no. But worms can use different parts of their body to do some of the jobs that our tongues do - like tasting and crushing food.
