All the Things That Drain Your EV Battery

Heating and cooling power consumption could range from a few hundred watts when the ambient temperature is close to optimal, 1-2 kW when the environment is very hot or cold, or even up to 5+ kW if the vehicle is starting off very cold and the battery needs to be warmed up by a resistive heater.”.

Can Super-Fast Battery Charging Fix the Electric Car?

If the goal is to charge up your electrical vehicle in, say, five minutes, that extra current meeting resistance means temperature-related problems inside the battery and out.“I question the wisdom of why we need to have 500-mile range in an electric car and also want fast charging in five minutes,” he says.

This Clever Gel Works Like a Vaccine for Wildfires

A typical fire retardant dropped from a plane, like the inorganic salt ammonium polyphosphate, or APP, works by sticking to the surface of vegetation and binding to carbon, creating a char layer that is resistant to burning.

Genetically Tweaked Viruses Just Saved a Very Sick Teen

The girl, though, has been receiving a cocktail of three phages from Hatfull’s lab since June—including two that were genetically modified to better attack her bacteria. The Cystic Fibrosis Foundation recently committed $100 million to better detect, prevent, and treat the chronic lung infections that often develop resistance as a result of antibiotic escalation.

Why a Geocode Is Not an Address

Why a Geocode Is Not an Address

According to the Puerto Rican government's recovery plan, the lack of 911-compliant addresses "makes it difficult for emergency responders to locate homes and businesses." So it is unsurprising that Puerto Ricans are resisting exclusively using a geocode addressing system, no matter what problems it can solve from a technical perspective.

Need an Ohm's Law Party Trick? Take a Light Bulb's Temperature

Finally, the resistance is really just a proportionality constant between the voltage and the current measured in units of ohms (often using the symbol Ω). Let's measure current and voltage to determine the temperature of a light bulb.

The Evolutionary Importance of Neutral vs. Adaptive Genes

The Evolutionary Importance of Neutral vs. Adaptive Genes

For most of the first half of the 20th century, population geneticists largely attributed genetic differences between populations and species to adaptation through positive selection.Motoo Kimura proposed in 1968 that most mutations might be neutral in effect rather than beneficial or harmful, and that shifts in the frequency of these neutral mutations dominated evolutionary change at the genomic level.Annual ReviewsBut in 1968, the famed population geneticist Motoo Kimura resisted the adaptationist perspective with his neutral theory of molecular evolution.
