A new rumor has suggested that NVIDIA will be using the new GeForce RTX branding on their upcoming GeForce 20 series graphics card lineup.

A University of Manchester PhD student has developed a prototype flexible heat shield for spacecraft that could reduce the cost of space travel and even aid future space missions to Mars.

Thirteen companies, including Boeing and Amazon billionaire Jeff Bezos’ Blue Origin space venture, will be doing studies for NASA on the future of commercial human spaceflight in low Earth orbit.

All of the studies are due in December, and are supposed to cost no more than $1 million each. NASA still has to negotiate the contract amounts with the study groups, but it expects the total cost of the effort to come in at around $11 million.

The fusion of a sperm cell with an egg cell is the very first step in the process that leads to new individuals in sexually reproducing species. Fundamental as this process may be, scientists are only now beginning to understand the complexities of how it works.

In a paper published in PLOS Biology, researchers have described the detailed structure of proteins that enable sperm-egg fusion in two different species: a flowering plant and a protozoan. The researchers hope that revealing the process in these species and their relatives might bring scientists a step closer to understanding it across sexual species, including humans and other vertebrates.

“It’s surprising to me that we still don’t know how a human sperm fuses with a human egg,” said Mark Johnson, an associate professor of biology at Brown University and a study co-author. “One of the things we hope this paper will do is establish a structural signature for the proteins that make gamete fusion work in these species so that we might be able to look for it in species where those protein mechanisms are still unknown.”

Loggers need to control their appetite for slow-growing trees to spare the Amazon rainforest from deforestation.

A new study by Ph.D. student J. Aaron Hogan points to changes in tree composition in a long-term study site in French Guiana to sound the alarm.

“We’re approaching a threshold where we’re forced to make some difficult decisions,” Hogan said. “Do we feed into demand for these tropical hardwoods? Or do we stick to our guns and say you can’t log any more until this stand is regenerated.”
