NASA has invested $725,000 in a new rocket system that could solve one of the major obstacles standing in our way of sending humans to Mars: travel time.

With current technology, a round-trip to the red planet would take almost two years. For astronauts, spending that much time in spaceflight comes with big health risks.

They’d be exposed to high levels of solar and cosmic radiation, the harmful effects of zero-gravity, and a long period of isolation.

In 2021, NASA’s Perseverance rover landed in the Jezero Crater on Mars. For the next three years, this astrobiology mission collected soil and rock samples from the crater floor for eventual return to Earth. The analysis of these samples is expected to reveal much about Mars’ past and how it transitioned from being a warmer, wetter place to the frigid and desiccated place we know today. Unfortunately, budget cuts have placed the future of the proposed NASA-ESA Mars Sample Return (MSR) mission in doubt.

As a result, NASA recently announced that it was seeking proposals for more cost-effective and rapid methods of bringing the samples home. This will consist of three studies by NASA and the Johns Hopkins University Applied Physics Laboratory (JHUAPL).

In addition, NASA has selected seven commercial partners for firm-fixed-price contracts for up to $1.5 million to conduct their own 90-day studies. Once complete, NASA will consider which proposals to integrate into the MSR mission architecture.

The performance of artificial intelligence (AI) tools, including large computational models for natural language processing (NLP) and computer vision algorithms, has been rapidly improving over the past decades. One reason for this is that datasets to train these algorithms have exponentially grown, collecting hundreds of thousands of images and texts often collected from the internet.

Training data for robot control and planning algorithms, on the other hand, remains far less abundant, in part because acquiring it is not as straightforward. Some computer scientists have thus been trying to create larger datasets and platforms that could be used to train computational models for a wide range of robotics applications.

In a recent paper, pre-published on the server arXiv and set to be presented at the Robotics: Science and Systems 2024 conference, researchers at the University of Texas at Austin and NVIDIA Research introduced one of these platforms, called RoboCasa.

Toddlers engage more regions of their brains around 16-months to help them develop important cognitive skills enabling them to follow simple instructions and control impulses. Findings from the study, led by the Universities of Bristol and Oxford, and published in Imaging Neuroscience, suggests 16 months is a critical period for brain development.

A child’s first two years of life are crucial for developing cognitive skills, particularly executive functions that help adjust thoughts, actions, and behaviours for everyday life.

Inhibitory control is one important executive function. This particular skills allows individuals to stop themselves from doing something out of impulse, habit or temptation. It’s already known that inhibitory control begins to develop in infancy and grows into early childhood. However, until now, the brain mechanisms involved in its development were unclear.

There are biological underpinnings to aging—and so researchers are investigating cell manipulations, transfusions of young blood, and chemical compounds that can mimic low-calorie diets.

Difffuse Studio has launched Procedural Crowds Pro, a new and improved version of their popular Geometry Nodes-powered add-on for Blender that enables you to quickly and easily populate your 3D environments with sizeable groups of characters.

Featuring over 30 unique photoscanned character models, the plug-in allows you to generate and customize various types of crowds, with options including an audience crowd, a circle crowd, follow curve, a marching formation, a random crowd, and more. The animations of the human characters will vary depending on the type of crowd you choose, including Idle, Walk, or Cheering. Moreover, the toolset also includes a neat feature that lets you add individual human characters and assign animations from a pre-defined list.

The earth will be habitable for 1.4 billion years but by then we could control the earth to make last forever same with the sun with high levels of technologies.

Humans will likely die long before our planet does.

Astronauts on spacewalks famously have to relieve themselves inside their spacesuits. Not only is this uncomfortable for the wearer and unhygienic, it is also wasteful, as—unlike wastewater on board the International Space Station (ISS)—the water in urine from spacewalks is not recycled.
