Dr Jennifer Garrison, PhD — Global Consortium for Reproductive Longevity & Equality — Buck Institute

Posted by in categories: biotech/medical, chemistry, life extension, neuroscience

Dr. Jennifer Garrison, PhD ( is Assistant Professor, Buck Institute for Research on Aging, Founder & Faculty Director, Global Consortium for Reproductive Longevity & Equality (, Assistant Professor in Residence, Cellular and Molecular Pharmacology, UCSF and Adjunct Assistant Professor of Gerontology, USC Leonard Davis School of Gerontology.

Dr. Garrison’s lab is interested in understanding how neuropeptides (a large class of signaling molecules which are secreted from neurons and transmit messages within the brain and across the nervous system) regulate changes in normal and aging animals as well in understanding how they control behavior at both the cell biological and neural circuit level.

New Solid-State Battery Surprises Researchers Who Created It

Posted by in categories: chemistry, energy, engineering

The study had been supported by LG Energy Solution’s open innovation, a program that actively supports battery-related research. LGES has been working with researchers around the world to foster related techniques.

Silicon anodes are famous for their energy density, which is 10 times greater than the graphite anodes most often used in today’s commercial lithium ion batteries. On the other hand, silicon anodes are infamous for how they expand and contract as the battery charges and discharges, and for how they degrade with liquid electrolytes. These challenges have kept all-silicon anodes out of commercial lithium ion batteries despite the tantalizing energy density. The new work published in Science provides a promising path forward for all-silicon-anodes, thanks to the right electrolyte.

Liquid experiments show how beautiful things can happen when chemicals meet

Posted by in categories: chemistry, energy

See how dormant potential energy explodes in psychedelic swirls when chemicals meet by combining oils, alcohols and inks in Petri dishes. Via the dazzling, colourful patterns that emerge, Gatti draws a line back to the surface of the Sun, where the constant churn of a volatile chemical reaction makes life on Earth possible.

Bacteria Makes Contaminated Water Drinkable

Posted by in categories: biotech/medical, chemistry, engineering, health

Bacteria may get a bad reputation in general, yet it’s actually generally healthy and serves an important role in many habitats, including human bodies. From supporting life on Earth to being employed in industrial and medicinal processes, bacteria have their figurative fingers in many pots — some varieties of bacteria can even filter tainted water and make it safe for human consumption.

A team of researchers from the Indian Institute of Technology, Banaras Hindu University (IIT-BHU) has found a bacteria that can do just that — Named “microbacterium paraoxydans strain VSVM IIT (BHU)” by the scientists, it can separate toxic hexavalent chromium from water in an effective and eco-friendly manner, according to a research published in the Journal of Environmental Chemical Engineering.

Hexavalent chromium is a heavy metal ion that is used in electroplating, welding, and chromate painting, among other things. It’s said to be responsible for health problems in humans like cancers, kidney and liver malfunctioning, and infertility. When compared to current approaches, the scientists believe that this bacterial strain, which can tolerate high amounts of hexavalent chromium, is particularly successful at eliminating the harmful substance from wastewater.

Nuclear waste interaction in the environment may be more complicated than once thought

Posted by in categories: chemistry, nuclear energy

Past and present nuclear activities (energy, research, weapon tests) have increased the urgency to understand the behavior of radioactive materials in the environment. Nuclear wastes containing actinides (e.g. plutonium, americium, curium, neptunium…) are particularly problematic as they remain radioactive and toxic for thousands of years.

Lawrence Livermore National Laboratory (LLNL) scientists and collaborators proposed a new mechanism by which nuclear waste could spread in the environment.

The new findings, that involve researchers at Penn State and Harvard Medical School, have implications for nuclear waste management and environmental chemistry. The research is published in the Journal of the American Chemical Society.

These Bacteria Digest Toxic Metals And Poop Out Tiny Gold Nuggets

Posted by in categories: biological, chemistry

Circa 2018 Imagine waste turned into gold.

No other life form on our planet has infiltrated every environment as successfully as the minuscule single cells of bacteria. Amongst their many roles in life on Earth, it turns out some of these microbes are also experts at purifying precious metals.

An international team of researchers has figured out how one metal-gobbling bacterium, Cupriavidus metallidurans, manages to ingest toxic metallic compounds and still thrive, producing tiny gold nuggets as a side-effect.

A 123,000 MPH Nuclear Rocket Could Reach Mars in Only One Month

Posted by in categories: chemistry, space travel

Four times faster than existing chemical rockets

In the seven months NASA estimates it would take to fly humans to Mars, any number of catastrophic failures could occur. That’s why Díaz said in a 2010 interview with Popular Science that “chemical rockets are not going to get us to Mars. It’s just too long a trip.” A conventional rocket must use its entire fuel supply in a single controlled explosion during launch before propelling itself towards Mars. There is no abort procedure, the ship will not be able to change course, and if any failure occurred, mission control would have a 10-minute communications delay, meaning they could find themselves helplessly watching on as the crew slowly dies.

Mars Was Always Destined to Die

Posted by in categories: alien life, chemistry

Mars is the solar system’s near-miss world. Earth may have gotten everything right when it came to sustaining life—atmosphere, water, proximity to the sun. Mercury, Venus and the outer planets, with their extreme temperatures and inhospitable chemistry, may have gotten everything wrong. Mars, on the other hand, came so close, yet fell short.

Thanks to data from rovers and other spacecraft, we know that the Red Planet once fairly sloshed with water—with dry deltas, riverbeds, and sea basins stamped into its surface. But 4 billion years ago, the Martian core cooled, shutting down the dynamo that sustained its magnetic field. That left the planet vulnerable to the solar wind, which clawed away the atmosphere, and allowed the Martian water to sputter into space. Before long—in geological terms—the planet was a desert.

At least that’s long been the thinking. But a new paper published Sept. 20 in the Proceedings of the National Academy of Sciences suggests otherwise. According to the new research, Mars was doomed from the start. Its small size—about half the diameter of Earth and less than one-ninth the mass—simply never produced the gravitational muscle to allow the planet to hold onto either its air or its water. With or without a magnetic field, Mars was destined to die.

Elon Musk Confirms “Challenges” With Toilet on Tourist Spacecraft

Posted by in categories: business, chemistry, Elon Musk, space travel, sustainability

Maybe try a 100 percent recycling rate for sewage and chemical extraction.

As if going to the bathroom in microgravity wasn’t complicated enough.

It sounds as though the four space tourists on SpaceX’s historic Inspiration4 flight last week had a bit of a smelly mishap. The Waste Management System experienced an “anomaly” — that’s code of “uh oh” in space jargon — with its suction fan causing the crew to struggle with doing their business while floating hundreds of miles above the surface.
