If a virtual world has ever left you feeling nauseous or disorientated, you’re familiar with cybersickness, and you’re hardly alone. The intensity of virtual reality (VR)—whether that’s standing on the edge of a waterfall in Yosemite or engaging in tank combat with your friends—creates a stomach-churning challenge for 30–80% of users.

In a first-of-its kind study, researchers at the University of Maryland recorded VR users’ using electroencephalography (EEG) to better understand and work toward solutions to prevent cybersickness. The research was conducted by Eric Krokos, who received his Ph.D. in computer science in 2018, and Amitabh Varshney, a professor of and dean of UMD’s College of Computer, Mathematical, and Natural Sciences.

Their study, “Quantifying VR cybersickness using EEG,” was recently published in the journal Virtual Reality.

A unique study of ancient diamonds has shown that the basic chemical composition of the Earth’s atmosphere which makes it suitable for life’s explosion of diversity was laid down at least 2.7 billion years ago. Volatile gases conserved in diamonds found in ancient rocks were present in similar proportions to those found in today’s mantle, which in turn indicates that there has been no fundamental change in the proportions of volatiles in the atmosphere over the last few billion years. This shows that one of the basic conditions necessary to support life, the presence of life-giving elements in sufficient quantity, appeared soon after Earth formed, and has remained fairly constant ever since.

Presenting the work at the Goldschmidt Geochemistry Conference, lead researcher Dr. Michael Broadly said, “The proportion and make-up of volatiles in the atmosphere reflects that found in the mantle, and we have no evidence of a significant change since these diamonds were formed 2.7 billion years ago.”

Volatiles, such as hydrogen, nitrogen, neon, and carbon-bearing species are light chemical elements and compounds, which can be readily vaporized due to heat, or pressure changes. They are necessary for life, especially carbon and nitrogen. Not all planets are rich in volatiles; Earth is volatile-rich, as is Venus, but Mars and the Moon lost most of their volatiles into space. Generally, a planet rich in volatiles has a better chance of sustaining life, which is why much of the search for life on planets surrounding distant stars (exoplanets) has focused on looking for volatiles.

‘Magneto-rotational hypernova’ soon after the Big Bang fuelled high levels of uranium, zinc in ancient stellar oddity.

A massive explosion from a previously unknown source — 10 times more energetic than a supernova — could be the answer to a 13-billion-year-old Milky Way mystery.

Astronomers led by David Yong, Gary Da Costa and Chiaki Kobayashi from Australia’s ARC Centre of Excellence in All Sky Astrophysics in 3 Dimensions (ASTRO 3D) based at the Australian National University (ANU) have potentially discovered the first evidence of the destruction of a collapsed rapidly spinning star — a phenomenon they describe as a “magneto-rotational hypernova”.

The international James Webb Space Telescope has passed the final mission analysis review for its launch on an Ariane 5 rocket from Europe’s Spaceport in French Guiana.

This major milestone, carried out with Arianespace, the Webb launch service provider, confirms that Ariane 5, the Webb spacecraft, and the flight plan are set for launch. It also specifically provides the final confirmation that all aspects of the launch vehicle and spacecraft are fully compatible.

During launch, the spacecraft experiences a range of mechanical forces, vibrations, temperature changes, and electromagnetic radiation. All technical evaluations performed by Arianespace on the mission’s key aspects, including the launch trajectory and payload separation, have shown positive results.

It’s an astonishing achievement — and in an eyebrow-raising twist, Simons says he plans to live forever, by turning himself into a cyborg.

It sounds like Simons has thought out his plan.

“This is the first puzzle piece in my goal of replacing body parts with mechanical parts,” Simons told De Telegraaf, adding that his goal is “immortality.”

Leaving earth to find new homes in space is an old dream of humanity and will sooner or later be necessary for our survival. The planet that gets the most attention is Mars, a small, toxic and energy poor planet that just about seems good enough for a colony of depressed humans huddled in underground cities.

But what if we think bigger? What if we take Venus, one of the most hostile and deadly places in the solar system and turn it into a colony? Not by building lofty cloud cities, but by creating a proper second earth? It might be easier than you think.

Novameat is eyeing the expansion of its plant-based 3D-printed steaks since launching its cutting-edge technology three years ago.

A Spanish start-up creating 3D-printed plant-based steaks is eyeing an expansion onto the mass market.

It follows a successful launch last year, and the company has plans to produce 500kg of the vegan meat products per hour.

Since developing the cutting-edge biotechnology in 2018, the company revealed scaling production goals. It hopes to soon offer products to restaurants across Spain.

The researchers explain that the development involves a new and very strong biological material, similar to collagen, which is non-toxic and causes no harm to the body’s tissues. The researchers believe that this new nanotechnology has many potential applications in medicine, including harvesting clean energy to operate devices implanted in the body (such as pacemakers) through the body’s natural movements, eliminating the need for batteries.

The study was led by Prof. Ehud Gazit of the Shmunis School of Biomedicine and Cancer Research at the Wise Faculty of Life Sciences, the Department of Materials Science and Engineering at the Fleischman Faculty of Engineering and the Center for Nanoscience and Nanotechnology, along with his lab team, Dr. Santu Bera and Dr. Wei Ji.

Also taking part in the study were researchers from the Weizmann Institute and a number of research institutes in Ireland, China and Australia. As a result of their findings, the researchers received two ERC-POC grants aimed at using the scientific research from the ERC grant that Gazit had previously won for applied technology. The research was published in the prestigious journal Nature Communications.

Prof. Gazit, who is also Founding Director of the Blavatnik Center for Drug Discovery, explains: Collagen is the most prevalent protein in the human body, constituting about 30% of all of the proteins in our body. It is a biological material with a helical structure and a variety of important physical properties, such as mechanical strength and flexibility, which are useful in many applications. However, because the collagen molecule itself is large and complex, researchers have long been looking for a minimalistic, short and simple molecule that is based on collagen and exhibits similar properties. About a year and a half ago, in the journal Nature Materials, our group published a study in which we used nanotechnological means to engineer a new biological material that meets these requirements.
