China unveils design for first waterless nuclear reactor

Posted by in categories: chemistry, engineering, nuclear energy, solar power, space travel, sustainability

CHINA’S NEW THORIUM-BASED NUCLEAR REACTOR is well situated for being adopted for Space applications.

China is slowly but steadily positioning itself to leap ahead of the US Space program. It is doing this without pomp and fanfare, and without the idea of a “space race,” simply based upon what it requires for its future.

1) Recent noteworthy progress on molten salt thorium reactors could be a key component of future Chinese space-worthiness. Originally designed by the USA’s Oak Ridge National Laboratory in the 1960’s, they were planned to be used for nuclear powered strategic bomber planes, before the nuclear submarine concept became adopted as more feasible. They were chosen because they can be miniaturized to the size of an aircraft. By the same token, they could conceivably be used in advanced atmospheric or space propulsion.

Private Israeli spyware used to hack cellphones of journalists, activists worldwide

Posted by in categories: business, cybercrime/malcode, military, mobile phones, surveillance

Military-grade spyware licensed by an Israeli firm to governments for tracking terrorists and criminals was used in attempted and successful hacks of 37 smartphones belonging to journalists, human rights activists, business executives and two women close to murdered Saudi journalist Jamal Khashoggi, according to an investigation by The Washington Post and 16 media partners.

The phones appeared on a list of more than 50000 numbers that are concentrated in countries known to engage in surveillance of their citizens and also known to have been clients of the Israeli firm, NSO Group, a worldwide leader in the growing and largely unregulated private spyware industry, the investigation found.

The list does not identify who put the numbers on it, or why, and it is unknown how many of the phones were targeted or surveilled. But forensic analysis of the 37 smartphones shows that many display a tight correlation between time stamps associated with a number on the list and the initiation of surveillance, in some cases as brief as a few seconds.

Texas patient becomes U.S.‘ first monkeypox case since 2003

Posted by in category: biotech/medical

A Dallas, Texas, resident who recently returned from Nigeria has tested positive for monkeypox, a rare virus similar to smallpox, local officials said Friday. Though this is the first confirmed case of the virus in the U.S. since 2003, officials said the public should not be concerned.

“While rare, this case is not a reason for alarm and we do not expect any threat to the general public,” Dallas County Judge Clay Jenkins said in a statement from Dallas County’s health department. Because passengers were wearing masks on the flight and in the airport, the health department said, “It’s believed the risk of spread of monkeypox via respiratory droplets to others on the planes and in the airports is low.”

Monkeypox, which is in the same family of viruses as smallpox, is a rare but potentially deadly viral infection that begins with flu-like symptoms and progresses to a rash on the face and body, according to the CDC. It tends to last two to four weeks. People who do not have symptoms are not capable of transmitting the virus, the health department said.

SUV39H2: A direct genetic link to autism spectrum disorders

Posted by in categories: biotech/medical, genetics, neuroscience

New research from the RIKEN Center for Brain Science (CBS) in Japan shows that a deficit in histone methylation could lead to the development of autism spectrum disorders (ASD). A human variant of the SUV39H2 gene led researchers to examine its absence in mice. Published in Molecular Psychiatry, the study found that when absent, adult mice exhibited cognitive inflexibility similar to what occurs in autism, and embryonic mice showed misregulated expression of genes related to brain development. These findings represent the first direct link between the SUV39H2 gene and ASD.

Genes are turned on and off throughout our development. But genetic variation means that what is turned off in some people remains turned on in others. This is why, for example, some adults can digest dairy products and others are lactose intolerant; the gene for making the enzyme lactase is turned off when some people become adults, but not others. One way that genes can be turned on and off is through a process called histone methylation in which special enzymes transfer methyl groups to histone proteins that are wrapped around DNA.

Variations in genes related to methylation during brain development can lead to serious problems. One such variation occurs in a rare disorder called Kleefstra Syndrome, in which a mutation prevents methylation of H3K9—a specific location on histone H3. Because Kleefstra Syndrome resembles autism in some ways, RIKEN CBS researchers led by Takeo Yoshikawa looked for autism-specific variations in genes that can modify H3K9. Among nine such genes, they found one variant in an H3K9 methyltransferase gene— SUV39H2 —that was present in autism, and the mutated SUV39H2 prevented methylation when tested in the lab. Similar loss-of-function results were found for the mouse version of the variant.

Astronomers push for global debate on giant satellite swarms

Posted by in category: satellites

Now, in what would be the biggest international step yet towards addressing these concerns, diplomats at a United Nations forum next month might discuss whether humanity has a right to ‘dark and quiet skies’. The debate could initiate a framework for how scientists and the public would deal with the flood of new satellites — with many more expected.


Working with the United Nations, scientists hope to establish standards for satellite ‘megaconstellations’ and reduce disruption of astronomical observations.

Kenyan entrepreneur turns plastic waste into bricks, stronger than concrete

Posted by in categories: engineering, sustainability, transportation

Plastic waste, a material that can take centuries or more to disappear, is causing irreparable damage to the planet. At least 8 million tons of plastic end up in the ocean each year. In many cases, specifically in more developed countries, plastic waste is disposed of responsibly and sent to facilities to be sorted, recycled, or recovered. However, plastic waste generated in developing countries typically ends up in dumps or open, uncontrolled landfills — most of which eventually enter the ocean either through transport by wind or tides or through waterways such as rivers or wastewater. Now, many companies are recycling this waste into useful products, such as sportswear, affordable homes, electric cars, roads, etc. One of them is Gjenge Makers Ltd, a sustainable, alternative, affordable building products manufacturing company that transforms plastic waste into durable building materials. These include paving blocks, paving tiles, and manhole covers.


Nzambi Matee has used her engineering skills to develop the process that involved mixing recycled waste plastic and sand. Matee gets the wasted plastic from packaging factories for free, although she pays for the plastic she gets from other recyclers. The company workers take plastic waste, mix it with sand, and heat it up, with the resulting brick being five to seven times stronger than concrete.
