Choosy Eggs May Pick Sperm for Their Genes, Defying Mendel’s Law
Posted by Kelvin Dafiaghor in category: genetics
The oldest law of genetics says that gametes combine randomly, but experiments hint that sometimes eggs select sperm actively for their genetic assets.

The Real Reason the Artemis I Launch Was Scrubbed
Posted by Greg Allison in categories: cosmology, space travel
What is the real reason the NASA Artemis I Launch got scrubbed on 29 Aug 21? NASA made a valiant attempt to launch the SLS Artemis I Moon Rocket this morning, but it was not to be. The launch was scrubbed. Get the real skinny here.

Drones are reshaping how rice is farmed in Vietnam
Posted by Raphael Ramos in categories: drones, food, sustainability
Vietnam is the world’s second-largest rice exporter, and XAG says its agricultural drones have become the “new favorite” of farmers that grow the crop.
Lê Thành Nguyên, at 62 years old, is one of the early adopters of agricultural drones in Vietnam. This year, he used drones on his seven-hectare rice farm for crop spraying, fertilization, and direct seeding by ordering the service from a local pilot team.

Yale Study Suggests That Evolution Can Be Predicted
Posted by Genevieve Klien in category: evolution
Evolution has long been thought to be random, however, a recent study suggests differently.
Evolution has long been thought of as a relatively random process, with species’ features being formed by random mutations and environmental factors and thus largely unpredictable.
But an international team of scientists headed by researchers from Yale University and Columbia University discovered that a specific plant lineage independently developed three similar leaf types repeatedly in mountainous places scattered across the Neotropics.

The media is going nuts over Elon Musk calling for more oil and gas at an energy conference in Norway, but the full quote is not being widely reported and brings some important context.
Earlier this year, Elon Musk called to drill for more oil, which raised a few eyebrows, but it was in the context of the Russian invasion of Ukraine and how it sent gas prices skyrocketing:

Europe Is Getting Serious About Making Space-Based Solar Power a Reality
Posted by Dan Breeden in categories: engineering, solar power, space, sustainability
Proposals for beaming solar power down from space have been around since the 1970s, but the idea has long been seen as little more than science fiction. Now, though, Europe seems to be getting serious about making it a reality.
Space-based solar power (SBSP) involves building massive arrays of solar panels in orbit to collect sunlight and then beaming the collected energy back down to Earth via microwaves or high-powered lasers. The approach has several advantages over terrestrial solar power, including the absence of night and inclement weather and the lack of an atmosphere to attenuate the light from the sun.
But the engineering challenge involved in building such large structures in space, and the complexities of the technologies involved, have meant the idea has remained on the drawing board so far. The director general of the European Space Agency, Josef Aschbacher, wants to change that.
