Astrobiologists have sent 18 different strains of bacteria up to the International Space Station.

They’re not meant to contaminate the already-kinda-gross orbital research center, but rather to determine whether the mineral-leaching microbes could help astronauts mine space rocks during future missions, Space.com reports.

If the so-called BioRock experiment pans out, the researchers behind the experiment argue that it could help humanity turn space rocks on the Moon or Mars into farmable soil for future human settlements.

Genetics hold far more sway over the mouse microbiome than transient environmental exposures, researchers reported July 26 in Applied and Environmental Microbiology. The results appear to contradict previous studies in humans that have found environmental factors to be more influential than genetics, and they add to an ongoing dialogue in the microbiome research community over how much control we hold over the bacterial communities in our guts.

Hila Korach-Rechtman, a microbiologist at the Israel Institute of Technology in Haifa, set out to identify the microbes in mice that become a fixture in the gut after being introduced through the environment. “We really wanted to find these bacteria that can be transferred and remain in the host, even though they have different genetics,” she says.

Newly discovered life forms inside our bodies profoundly affect our health – and provide a glimpse of the vast and mysterious biological “dark matter” within us.

A KAIST team has designed a novel strategy for synthesizing single-crystalline graphene quantum dots, which emit stable blue light. The research team confirmed that a display made of their synthesized graphene quantum dots successfully emitted blue light with stable electric pressure, reportedly resolving the long-standing challenges of blue light emission in manufactured displays. The study, led by Professor O Ok Park in the Department of Chemical and Biological Engineering, was featured online in Nano Letters on July 5.

Graphene has gained increased attention as a next-generation material for its heat and electrical conductivity as well as its transparency. However, single and multi-layered graphene have characteristics of a conductor so that it is difficult to apply into semiconductor. Only when downsized to the nanoscale, semiconductor’s distinct feature of bandgap will be exhibited to emit the light in the graphene. This illuminating featuring of dot is referred to as a graphene quantum dot.

Conventionally, single-crystalline graphene has been fabricated by chemical vapor deposition (CVD) on copper or nickel thin films, or by peeling graphite physically and chemically. However, graphene made via chemical vapor deposition is mainly used for large-surface transparent electrodes. Meanwhile, graphene made by chemical and physical peeling carries uneven size defects.

Lux Capital, a New York-based venture capital firm, has raised more than $1 billion across two new funds to back companies on “the cutting edge of science.” The firm raised $500 million for its sixth flagship early-stage fund and another $550 million for an opportunity fund focused on growth-stage investments. Limited partners include global foundations, university endowments, and tech billionaires.

Lux also announced a new hire: Deena Shakir, formerly of GV (Google Ventures), has joined as an investment partner.

To the regular person, Lux’s investments are considered moonshot. The firm has backed entrepreneurs that are working on everything from neurostimulation to nuclear energy to synthetic biology. During my last interview with co-founder and managing partner Josh Wolfe, I actually called one of his portfolio companies “freaking crazy.”

Quantum sensors based on nitrogen-vacancy (NV) centers in diamond are a promising detection mode for nuclear magnetic resonance spectroscopy due to their micron-scale detection volume and noninductive-based sample detection requirements. A challenge that exists is to sufficiently realize high spectral resolution coupled with concentration sensitivity for multidimensional NMR analysis of picolitre sample volumes. In a new report now on Science Advances, Janis Smits and an interdisciplinary research team in the departments of High Technology Materials, Physics and Astronomy in the U.S. and Latvia addressed the challenge by spatially separating the polarization and detection phases of the experiment in a microfluidic platform.

They realized a spectral resolution of 0.65±0.05 Hz, an order-of-magnitude improvement compared with previous diamond NMR studies. Using the platform, they performed 2-D correlation spectroscopy of liquid analytes with an effective detection volume of ~40 picoliters. The research team used diamond quantum sensors as in-line microfluidic NMR detectors in a major step forward for applications in mass-limited chemical analysis and single-cell biology.

Nuclear magnetic resonance (NMR) spectroscopy is a powerful and well-established technique for compositional, structural and functional analysis in a variety of scientific disciplines. In conventional NMR spectrometry the signal-to-noise ratio (SNR) is strongly dependent on the external field strength (B₀). As the spectral resolution increased, the B₀ increased as well, motivating the development of increasingly large and expensive superconducting magnets for improved resolution and SNR, resulting in a two-fold increase in field strength within the past 25 years.
