Creator of Wolfram Alpha Has a Bold Plan to Find a New Fundamental Theory of Physics

Posted by in categories: computing, information science, neuroscience, physics

Stephen Wolfram is a cult figure in programming and mathematics. He is the brains behind Wolfram Alpha, a website that tries to answer questions by using algorithms to sift through a massive database of information. He is also responsible for Mathematica, a computer system used by scientists the world over.

Last week, Wolfram launched a new venture: the Wolfram Physics Project, an ambitious attempt to develop a new physics of our Universe.

The new physics, he declares, is computational. The guiding idea is that everything can be boiled down to the application of simple rules to fundamental building blocks.

Astronomers Just Identified 19 More Asteroids They Think Are Interstellar

Posted by in categories: asteroid/comet impacts, existential risks, space travel

The Solar System has been here for a long time. So, when ’Oumuamua was spotted in 2017, it was almost a dead cert it wasn’t the only object from interstellar space to visit us over that 4.57 billion-year history. Then comet 2I/Borisov showed up last year. That basically clinched it.

But where are the rest of our interstellar visitors? We’ll probably find a few more flying in from the wilds in the coming years. And, according to new research, a whole bunch of interstellar asteroids have been hanging out right here in the Solar System for a very long time.

Based on how they move around the Sun, a team of researchers has identified 19 asteroids they think were captured from another star, way back when the Solar System was just a few million years old.

A study finds neuropeptide somatostatin enhances visual processing

Posted by in categories: biotech/medical, neuroscience

Researchers have confirmed that neuropeptide somatostatin can improve cognitive function in the brain. A research group of Professor Seung-Hee Lee from the Department of Biological Sciences at KAIST found that the application of neuropeptide somatostatin improves visual processing and cognitive behaviors by reducing excitatory inputs to parvalbumin-positive interneurons in the cortex.

This study, reported at Science Advances on April 22nd, sheds a new light on the therapeutics of neurodegenerative diseases. According to a recent study in Korea, one in ten seniors over 65 is experiencing dementia-related symptoms in their daily lives such as memory loss, cognitive decline, and motion function disorders. Professor Lee believes that somatostatin treatment can be directly applied to the recovery of cognitive functions in Alzheimer’s disease patients.

Professor Lee started this study noting the fact that the level of somatostatin expression was dramatically decreased in the cerebral cortex and cerebrospinal fluid of Alzheimer’s disease patients.

Accidentally Released Results Suggest Potential COVID-19 Drug Failed a Human Trial

Posted by in category: biotech/medical

The experimental coronavirus treatment remdesivir has failed in its first randomized clinical trial, inadvertently released results showed Thursday, dampening expectations for the closely watched drug.

But Gilead Sciences, the company behind the medicine, disputed how the now-deleted post had characterized the findings, saying the data showed a “potential benefit.”

The summary said the Chinese trial involved 237 patients, with 158 on the drug and 79 in a control group. Remdesivir was stopped early in 18 patients because of side effects.

Rapid development of an inactivated vaccine for SARS-CoV-2

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

April 2020


The COVID-19 pandemic caused by SARS-CoV-2 has brought about an unprecedented crisis, taking a heavy toll on human health, lives as well as the global economy. There are no SARS-CoV-2-specific treatments or vaccines available due to the novelty of this virus. Hence, rapid development of effective vaccines against SARS-CoV-2 is urgently needed. Here we developed a pilot-scale production of a purified inactivated SARS-CoV-2 virus vaccine candidate (PiCoVacc), which induced SARS-CoV-2-specific neutralizing antibodies in mice, rats and non-human primates. These antibodies potently neutralized 10 representative SARS-CoV-2 strains, indicative of a possible broader neutralizing ability against SARS-CoV-2 strains circulating worldwide. Immunization with two different doses (3μg or 6 μg per dose) provided partial or complete protection in macaques against SARS-CoV-2 challenge, respectively, without any antibody-dependent enhancement of infection. Systematic evaluation of PiCoVacc via monitoring clinical signs, hematological and biochemical index, and histophathological analysis in macaques suggests that it is safe. These data support the rapid clinical development of SARS-CoV-2 vaccines for humans.

One Sentence Summary A purified inactivated SARS-CoV-2 virus vaccine candidate (PiCoVacc) confers complete protection in non-human primates against SARS-CoV-2 strains circulating worldwide by eliciting potent humoral responses devoid of immunopathology.

The authors have declared no competing interest.

The nature of Neanderthal introgression revealed by 27,566 Icelandic genomes

Posted by in categories: biotech/medical, genetics

Human evolutionary history is rich with the interbreeding of divergent populations. Most humans outside of Africa trace about 2% of their genomes to admixture from Neanderthals, which occurred 50–60 thousand years ago1. Here we examine the effect of this event using 14.4 million putative archaic chromosome fragments that were detected in fully phased whole-genome sequences from 27,566 Icelanders, corresponding to a range of 56,388–112,709 unique archaic fragments that cover 38.0–48.2% of the callable genome. On the basis of the similarity with known archaic genomes, we assign 84.5% of fragments to an Altai or Vindija Neanderthal origin and 3.3% to Denisovan origin; 12.2% of fragments are of unknown origin. We find that Icelanders have more Denisovan-like fragments than expected through incomplete lineage sorting. This is best explained by Denisovan gene flow, either into ancestors of the introgressing Neanderthals or directly into humans. A within-individual, paired comparison of archaic fragments with syntenic non-archaic fragments revealed that, although the overall rate of mutation was similar in humans and Neanderthals during the 500 thousand years that their lineages were separate, there were differences in the relative frequencies of mutation types—perhaps due to different generation intervals for males and females. Finally, we assessed 271 phenotypes, report 5 associations driven by variants in archaic fragments and show that the majority of previously reported associations are better explained by non-archaic variants.
