Perseverance’s Robotic Arm Starts Conducting Science Program

Posted by in categories: biological, robotics/AI, science, space

NASA’s newest Mars rover is beginning to study the floor of an ancient crater that once held a lake.

NASA’s Perseverance rover has been busy serving as a communications base station for the Ingenuity Mars Helicopter and documenting the rotorcraft’s historic flights. But the rover has also been busy focusing its science instruments on rocks that lay on the floor of Jezero Crater.

What insights they turn up will help scientists create a timeline of when an ancient lake formed there, when it dried, and when sediment began piling up in the delta that formed in the crater long ago. Understanding this timeline should help date rock samples – to be collected later in the mission – that might preserve a record of ancient microbes.

This lab-grown meat grows on spinach skeletons

Posted by in categories: biological, food, sustainability

In the last decade, lab-grown meat has emerged a sustainable alternative to traditional livestock methods. Livestock strain Earth’s land resources and account for about 14.5 percent of global greenhouse gas emissions. But while scientists can grow thin sheets of cow meat and scrape it together to form a patty, people eat with their eyes as much as their mouths. For lab-grown meat to replace a fresh steak, it needs to look like a steak.

Growing lab-based meat into 3D structures is difficult because it needs constant delivery of oxygen and nutrients. In living organisms, vascular systems fill that need. Researchers at Boston College previously showed that skeletonized spinach leaves, stripped of everything but their veiny, oxygen-dispersing, vascular system, can support patches of heart muscle cells. Now, they show that lab-grown meat can grow on skeletonized spinach, an essential step to growing steak-shaped meat in the lab.

Self-generating yarn made from graphene oxide strands

Posted by in categories: biological, physics

A team of researchers from Zhejiang University, Xi’an Jiaotong University and Monash University has developed a way to bind multiple strands of graphene oxide into a thick cable. In their paper published in the journal Science, the group describes their process and possible uses for it. Rodolfo Cruz-Silva and Ana Laura Elías with Shinshu University and Binghamton University have published a Perspectives piece in the same issue outlining the work by the researchers and explaining why they believe the technique could prove useful in manufacturing efforts.

In recent years, have been exploring the possibility of making products using total or partial self-assembly as a way to produce them faster or at less cost. In where two materials self-assemble into a third material, scientists describe this as a fusion process, borrowing terminology from physics. So when a single material spontaneously separates into two or more other materials, they refer to it as a fission process. In this new effort, the researchers have developed a technique for creating graphene-oxide-based yarn that exploits both processes.

The work by the team is very basic. They created multiple strands of graphene oxide and then dunked them into a solvent for 10 minutes. When the strands were pulled from the solution, they banded together forming a cord, or single strand of yarn. They also developed a means for reversing the process—dunking the strand of yarn in a different solvent solution.

Light Therapy Helps Veterans Treated for Traumatic Brain Injury

Posted by in categories: biological, health, neuroscience

Summary: Morning bright light therapy improved both physical and mental health symptoms, including cognitive function and sleep quality, in veterans who suffered TBI.

GFS 2020 — Aubrey de Grey — Rejuvenation Biotechnology: why age may soon cease to mean aging

Posted by in categories: biological, biotech/medical, health

Between 19:39 and 24 minutes we have Aubrey giving a list of companies and stating that investing is now taking off. Project 21 seems to be on track to start next year, and therapies available in 10–15 years will add 30 years to life and really be indefinite beyond that.


Rejuvenation Biotechnology: why age may soon cease to mean aging.
People are living longer — no longer because of reduced child mortality, but because we are postponing the ill-health of old age. But we’ve seen nothing yet: regenerative medicine and other new medicines will eventually be so comprehensive that people will stay truly youthful however long they live, which means they may mostly live very long indeed.

Deep under the ocean, microbes are active and poised to eat whatever comes their way

Posted by in categories: biological, food, space

The subseafloor constitutes one of the largest and most understudied ecosystems on Earth. While it is known that life survives deep down in the fluids, rocks, and sediments that make up the seafloor, scientists know very little about the conditions and energy needed to sustain that life.

An interdisciplinary research team, led from ASU and the Woods Hole Oceanographic Institution (WHOI), sought to learn more about this ecosystem and the microbes that exist in the subseafloor. The results of their findings were recently published in Science Advances, with ASU School of Earth and Space Exploration assistant professor and geobiologist Elizabeth Trembath-Reichert as lead author.

To study this type of remote ecosystem, and the microbes that inhabit it, the team chose a location called North Pond on the western flank of the mid-Atlantic Ridge, a plate boundary located along the floor of the Atlantic Ocean.
