Though implicit bias - the belief that you are prejudiced, it's just a matter of degree - is controversial, that's only because it lacks scientific footing. A new study seeks to advance that.

We all have likes and dislikes but when it becomes bias or prejudice is subjective. If you prefer dark haired men, does that mean you are prejudiced against redheads? It does, in things like the Implicit Association Test. 

Drosophila flies lose long-term memory of a traumatic event when kept in the dark, and the authors of a new study link that to a specific molecular mechanism responsible. 

Memories are difficult to erase but breakthroughs could be important for sufferers of trauma, because while most normal events won't be recalled even the same day, a particularly shocking event may be consolidated into our long-term memory, whereby new proteins are synthesized and the neuronal circuits in our brain are modified.

A rock carving found in the Teymareh rock art site in Khomein county in Central Iran is part man and part mantis, with six limbs.  Was it a mistake? The world's first graphic novel? A way to inspire warriors to fight their foes? We may never know. It's hard to even know its age.

Rock carvings - petroglyphs - of invertebrate animals are rare, so for a new paper  entomologists teamed up with archaeologists to try and identify the motif. They compared the carving with others around the world and with the local six-legged creatures which its prehistoric artists could have encountered.

The 2019 version of the coronavirus that has spread to about 50 countries across the world doesn't appear to be transmittable from pregnant mothers to newborns at birth. The new case study is the second out of China within the last month to confirm that mothers infected with coronavirus disease 2019 (COVID-19) during pregnancy did not infect their babies.

All four mothers in the current study gave birth at Wuhan's Union Hospital while infected. Wuhan in Hubei Province was the epicenter of the current outbreak that has sickened more than 100,000 people worldwide and killed more than 3,400, mostly in China. 

A new paper shows that a selling feature of electric cars, fast-charging stations along highways, actually subject batteries to high temperatures and high resistance that can cause them to crack, leak, and lose their storage capacity.

If you are experiencing symptoms such as fatigue, nausea, dizziness, decreased energy, feeling faint and heartbeat alterations after starting the fad keto diet, you may not have coronavirus or influenza, it may just be the diet.

These are low-carbohydrate, high-fat diets which result in elevated levels of ketones in the blood. A Frontiers in Nutrition study reports that symptoms peak in the first 7 days but dwindle after four weeks. Severity is a wide range because the data are anecdotal, much like the claims of health benefits.
