Alzheimer’s: New gene may drive earliest brain changes

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

A newly discovered Alzheimer’s gene may drive the first appearance of amyloid plaques in the brain, according to a study led by researchers at Columbia University Irving Medical Center.

Some variants of the gene, RBFOX1, appear to increase the concentration of protein fragments that make up these plaques and may contribute to the breakdown of critical connections between neurons, another early sign of the disease.

The finding could lead to new therapies that prevent Alzheimer’s and better ways of identifying people with the greatest risk of developing the disease.

Why aren’t people smarter? The dubious benefits of intelligence, real or artificial

Posted by in category: futurism

Intelligence — real or artificial — is supposed to be a big advantage. But we’ve had millions of years to evolve real intelligence and dumbness is rampant. Which raises the question: If intelligence is so good, why aren’t we more like Mr. Spock and less like Captain Kirk?

After 136 Earthquakes in 24 Hours, Philippines Volcano Enters ‘Period of Unrest’

Posted by in category: government

“The local government units and the public are strongly reminded that entry into the 4-km radius permanent danger zone must be strictly prohibited due to the further possibilities of sudden and hazardous steam-driven or phreatic eruptions,” the institute warned.

The Phivolcs said that it has recorded 136 volcano-tectonic earthquakes—earthquakes caused by the movement of magma beneath the surface of the Earth—on the western flanks during the 24-hour observation period.

It added that four of these earthquakes recorded between 1 a.m. to 2.06 a.m. on Monday were felt in La Carlota City and Bago City in Negros Occidental province and Canlaon City in Negros Oriental province.

7.4 magnitude earthquake felt off coast of Mexico

Posted by in category: futurism

A 7.4 magnitude earthquake was felt off the southern coast of Mexico in the state of Oaxaca, prompting a forecast of potential tsunami waves, the country’s National Seismological Service reported Tuesday afternoon.

The quake occurred at 10:29 a.m. central time, with an epicenter near El Coyul, 6.8 miles southwest of Santa María Zapotitlán in Oaxaca. The damage in the state is considered light to moderate according to the U.S. Geological Survey (USGS).

The USGS estimates the earthquake itself could result in as many as 100 fatalities and $100 million in damage.

Scientists produce first open source all-atom models of COVID-19 ‘spike’ protein

Posted by in categories: biotech/medical, chemistry

The virus SARS coronavirus 2 (SARS-CoV-2) is the known cause of coronavirus disease 2019 (COVID-19). The “spike” or S protein facilitates viral entry into host cells.

Now a group of researchers from Seoul National University in South Korea, University of Cambridge in UK, and Lehigh University in USA, have worked together to produce the first open-source all-atom models of a full-length S . The researchers say this is of particular importance because the S protein plays a central role in viral entry into cells, making it a main target for vaccine and antiviral drug development.

Speeding-Up Quantum Computing Using Giant Atomic Ions – 100 Million Times Larger Than Normal Atoms

Posted by in categories: computing, particle physics, quantum physics

Trapped Rydberg ions can be the next step towards scaling up quantum computers to sizes where they can be practically usable, a new study in Nature shows.

Different physical systems can be used to make a quantum computer. Trapped ions that form a crystal have led the research field for years, but when the system is scaled up to large ion crystals this method gets very slow. Complex arithmetic operations cannot be performed fast enough before the stored quantum information decays.

A Stockholm University research group may have solved this problem by using giant Rydberg ions, 100 million times larger than normal atoms or ions. These huge ions are highly interactive and, therefore, can exchange quantum information in less than a microsecond.
