SpaceX Completed A Record-breaking Launch Manifest In 2020

Posted by in categories: Elon Musk, mathematics, robotics/AI, space travel

SpaceX’s fleet of reusable Falcon 9 rockets enabled it to conduct more missions in 2020 than ever before. SpaceX completed a record-breaking launch manifest this year, it conducted 26 rocket launches –the most annual launches it has performed in history. Rocket reusability has played a significant role in increasing launch cadence. Falcon 9 is capable of launching payload to orbit and returning from space to land vertically on landing pads and autonomous droneships at sea. To date, SpaceX has landed 70 orbital-class Falcon 9 boosters and reused 49. This year the company accomplished flying two particular rocket boosters 7 times. Engineers aim to reuse a first-stage booster at least 10 times to reduce the cost of spaceflight. The most reused Falcon 9 rockets that reached 7 reflights this year are two first-stage boosters identified as B1051 and B1049. SpaceX is just three flights away from achieving 10 reflights. SpaceX officials state Falcon 9 [Block 5] is designed to perform up to 100 reflights.

Stephen Marr, a spaceflight photographer who goes by the name @spacecoast_stve on Twitter, shared a photo collage of all the Falcon 9 boosters used in 2020, “SpaceX carried out a record-breaking 26 launches this year, but how many boosters did it take to get it done? The answer is 11. And here they are!” he wrote. SpaceX founder Elon Musk replied to Marr’s tweet –“Falcon was 25% of successful orbital launches in 2020, but maybe a majority of payload to orbit. Anyone done the math?” he said.

Tesla Model Y Police Car Makes World Debut in New York

Posted by in categories: sustainability, transportation

It seems even police cars are moving to Tesla. 😃


Tesla Model Y enters the world of crime-fighting, commissioned by the Hastings-on-Hudson Police Department, Westchester County, New York. This is the first Model Y that has already been purchased and equipped as a police department vehicle in the world.

On December 21, the Hastings-on-Hudson Police Department shared the great news with the community via their Facebook. The PD has acquired and has already received their first electric car—Tesla Model Y. Police Chief David Dosin said the Westchester County Department was the first in the county to receive delivery of the all-electric police car, as the department is committed to alternative fuels and clean technologies.

Super Gonorrhea May Be Spreading From Antibiotic Overuse For Covid-19 Coronavirus

Posted by in category: biotech/medical

You want 2021 to be super. But not in a super gonorrhea type of way.

“Super gonorrhea” is trending on Twitter right now because, well, why not? It’s 2020, after all. And what better thing to have trend at the end of a year that brought us the Covid-19 coronavirus pandemic, a shortage of basically everything, constant drama in the White House, and a Presidential election that just won’t end? Consider this sexually transmitted infection to be the pie à la mode, the night cap, the final wipe of 2020.

New Drug Starves Cancer Cells

Posted by in category: biotech/medical

This new anti-cancer drug will be attacking the mitochondria of cancer cells. They do this by inhibiting the enzyme mitochondrial RNA polymerase (POLRMT).

Differentiated tissues are said to be tolerant of the inhibition of this enzyme while rapidly proliferating cells are impacted more.


The compound was found to reduce tumor growth in mice.

Wait, What? New Research Says Internet Use Is Killing Your Memory

Posted by in categories: internet, neuroscience

This doesn’t sound good. 😃


The scientists put hundreds of participants through memory and cognitive tasks as well as brain scans, according to the research, published last month in the journal World Psychiatry.

Joseph Firth, the Western Sydney University scientist who led the project, described in a press release how the internet’s design is changing both the structure and abilities of the human brain.

How to get people from Earth to Mars (and safely back again)

Posted by in category: space travel

A lot of risk here. I do also recall estimates for orbital refueling bringing the trip to Mars down to 3 months, but that appears not to be the case.


There are many things humanity must overcome before any return journey to Mars is launched. Let’s dive in.

A Major Malformation Illustrates the Incredible Plasticity of the Human Brain

Posted by in categories: biotech/medical, neuroscience

People born without a corpus callosum do not have a bridge between the two cerebral hemispheres. Neuroscientists from UNIGE have shown how the brain manages to adapt.

One in 4000 people is born without a corpus callosum, a brain structure consisting of neural fibers that are used to transfer information from one hemisphere to the other. A quarter of these individuals do not have any symptoms, while the remainder either have low intelligence quotients or suffer from severe cognitive disorders. In a study published in the journal Cerebral Cortex, neuroscientists from the University of Geneva (UNIGE) discovered that when the neuronal fibers that act as a bridge between the hemispheres are missing, the brain reorganizes itself and creates an impressive number of connections inside each hemisphere. These create more intra-hemispheric connections than in a healthy brain, indicating that plasticity mechanisms are involved. It is thought that these mechanisms enable the brain to compensate for the losses by recreating connections to other brain regions using alternative neural pathways.

The corpus callosum develops in utero between the tenth and twentieth week of gestation. Agenesis of the corpus callosum is a congenital brain malformation in which this brain structure fails to develop, resulting in one out of 4000 babies born without a corpus callosum. When it is missing, nothing replaces this structure measuring about ten centimeters, with the exception of cerebrospinal fluid. This means that the information transmitted from one hemisphere to the other can no longer be conveyed by the neuronal projections from the corpus callosum. “Their role in a healthy brain,” begins Vanessa Siffredi, a researcher in UNIGE’s Faculty of Medicine, “is to ensure the functioning of various cognitive and sensorimotor functions.” Surprisingly, 25% of people with this malformation have no visible signs; 50% have average intelligence quotients and learning difficulties; and the remaining 25% suffer from severe cognitive disorders.
