Changes in the human sex ratio at birth—defined as the percentage of newborns that are boys—are associated with the presence of air and water pollutants, but are not predictably associated with seasonality or weather, according to a new study of more than 6 million births in the US and Sweden.

Jon Kaas, Gertrude Conaway Vanderbilt Chair in Social and Natural Sciences, Distinguished Centennial Professor of Psychology and associate professor of cell and developmental biology, received the Ralph W. Gerard Prize in Neuroscience, the highest recognition from the Society for Neuroscience, for his pathbreaking work in illuminating the structure and function of the cerebral cortex and plasticity in the developing and adult brain.

Through mapping the cerebral cortex in 30 mammalian species over his career, Kaas has shown the functional and structural organization of the visual and somatosensory—that is, sensations that span the body, such as warmth—systems in detail. Through detailed pictorial construction and electrophysical mapping, Kaas reversed a scientific dogma that brain plasticity only occurs in early life. This has led to new approaches to rehabilitation from brain damage after stroke, from macular degeneration or from motor system disorders and injuries.

“I’m pleased to share this award with Bob Desimone who has done such wonderful research, and who we once tried to convince to move to Vanderbilt,” Kaas said. “From my first days at Vanderbilt, I have worked with outstanding graduate students, undergraduates and postdocs, who made everything possible. The support of members of my Department and other faculty at Vanderbilt has been especially important.”

A major milestone has been breached in the quest for fusion energy.

For the first time, a fusion reaction has achieved a record 1.3 megajoule energy output – and for the first time, exceeding energy absorbed by the fuel used to trigger it.

Although there’s still some way to go, the result represents a significant improvement on previous yields: eight times greater than experiments conducted just a few months prior, and 25 times greater than experiments conducted in 2018. It’s a huge achievement.

Engie and Macquarie to build 150MW one hour battery at site of shuttered Hazelwood coal generator.

French energy giant Engie and Macquarie’s Green Investment Group are to jointly fund the construction of a 150MW/150MWh big battery at the site of the now closed Hazelwood brown coal generator.

The announcement, which comes four years after Engie closed what was Australia’s dirtiest power station, continues the trend of using the sites of closed or ageing coal and gas plants to build battery storage to support the switch to 100 per cent renewables.

The robot navigates using sensors and removes weeds mechanically without the need for chemicals. The LiDAR (light detection and ranging) scanners installed in the weed killer continuously emit laser pulses as the vehicle moves, which are then reflected by objects in the surrounding area. This produces a 3D point cloud of the environment, which helps mobile weed killers to find their way and determine the position of plants or trees. “AMU-Bot is not yet able to classify all plants; however, it can recognize crops such as trees and shrubs in the rows of the tree nursery cultivations,” said the team leader Kevin Bregler.

The weeds in the spaces between the plants or trees are also reliably eliminated. To do this, the manipulator moves into the gaps between the crops. The weeds do not need to be collected separately and are left on the ground to dry out. Thanks to its caterpillar drive, the self-driving weed killer moves along the ground with ease and is extremely stable. Even holes in the ground created when saplings are removed do not pose a problem for AMU-Bot. The AMU-Bot platform is economical, robust, easy to use, and at the same time highly efficient.

The project is funded by the German Federal Office of Agriculture and Food. The AMU-Bot platform relies on the ingenious interaction of three sophisticated modules: caterpillar vehicle, navigation system, and manipulator. Bosch is responsible for the navigation and the sensor system, while KommTek developed the caterpillar drive. The Fraunhofer IPA designed the height-adjustable manipulator, including rotary harrows, and was responsible for overall coordination.

In the novel-turned-movie Ready Player One by Ernest Cline, the protagonist escapes to an online realm aptly called OASIS. Instrumental to the OASIS experience is his haptic (relating to sense of touch) bodysuit, which enables him to move through and interact with the virtual world with his body. He can even activate tactile sensations to feel every gut punch, or a kiss from a badass online girl.

While no such technology is commercially available yet, the platform Meta, formerly known as Facebook, is in the early stages of creating haptic gloves to bring the virtual world to our fingertips. These gloves have been in the works for the past seven years, the company recently said, and there’s still a few more to go.

These gloves would allow the wearer to not only interact with and control the virtual world, but experience it in a way similar to how one experiences the physical world. The wearer would use the gloves in tandem with a headset for AR or VR. A video posted by Meta in a blog shows two users having a remote thumb-wrestling match. In their VR headsets, they see a pair of disembodied hands reflecting the motions that their own hands are making. In their gloves, they feel every squeeze and twitch of their partner’s hand—at least that’s the idea.

Eureka Robotics, a tech spin-off from Nanyang Technological University, Singapore (NTU Singapore), has developed a technology, called Dynamis, that makes industrial robots nimbler and almost as sensitive as human hands, able to manipulate tiny glass lenses, electronics components, or engine gears that are just millimeters in size without damaging them.

This proprietary force feedback technology developed by NTU scientists was previously demonstrated by the Ikea Bot which assembled an Ikea chair in just 20 minutes. The breakthrough was first published in Science in 2018 and went viral on the internet when it could match the dexterity of human hands in assembling furniture.

NTU Associate Professor Pham Quang Cuong, Co-founder of Eureka Robotics, said they have since upgraded the software technology, which will be made available for a large number of industrial robots worldwide by Denso Wave, a market leader in industrial robots, which is part of the Toyota Group.

Before NASA deploys its Artemis Gateway in orbit around the moon, the agency will launch a different, but related “Gateway” at its Kennedy Space Center Visitor Complex. “Gateway: The Deep Space Launch Complex” is slated to open in March 2022.
