An ongoing long-term trial suggests high levels of amyloid proteins in the brain do serve as an early sign of Alzheimer’s disease before cognitive decline becomes apparent.

A new study presenting the first data from a long-running US government trial is suggesting high levels of amyloid proteins in the brains of cognitively normal older adults can be an effective presymptomatic sign of early stage Alzheimer’s disease.

Over the last few decades, the amyloid hypothesis has guided the majority of research into an Alzheimer’s disease treatment. The idea is that a build up of toxic amyloid proteins in the brain, called plaques, is the primary degenerative driver behind the disease.

The Spanish government is taking action in the wake of the coronavirus outbreak.

So-called zero-day exploits—hacking techniques that take advantage of secret software flaws—were once the calling card of only the most sophisticated hackers. But today, the global map of zero-day hacking has expanded far beyond the United States, Russia, and China, as more countries than ever buy themselves a spot on it.

Security and intelligence firm FireEye today released a sweeping analysis of how zero days have been exploited worldwide over the last seven years, drawing in data from other security research organizations’ reporting as well as Google Project Zero’s database of active zero days. FireEye was able to link the use of 55 of those secret hacking techniques to state-sponsored operations, going so far as to name which country’s government it believes to be responsible in each case.

The resulting map and timeline, with a tally of which countries have used the most zero days over the last decade, are far from comprehensive. Countries like the US almost certainly have used zero days that remain undetected, FireEye acknowledges, and many others couldn’t be pinned with certainty on any particular country. But it does show how the collection of countries using those hacking techniques now includes less expected players like the United Arab Emirates and Uzbekistan.

The Royal Society is to create a network of disease modelling groups amid academic concern about the nation’s reliance on a single group of epidemiologists at Imperial College London whose predictions have dominated government policy, including the current lockdown.

It is to bring in modelling experts from fields as diverse as banking, astrophysics and the Met Office to build new mathematical representations of how the coronavirus epidemic is likely to spread across the UK — and how the lockdown can be ended.

The first public signs of academic tensions over Imperial’s domination of the debate came when Sunetra Gupta, professor of theoretical epidemiology at Oxford University, published a paper suggesting that some of Imperial’s key assumptions could be wrong.

This week, the U.S. government approved the first blood test in the country that will look for the antibodies produced by the body to fight the novel coronavirus. Such a test can reveal whether someone is actively infected by the virus, as well as whether they were previously infected but recovered. While these tests are very much needed to better understand the scale of the outbreak, they have a few major limitations.

On Thursday, the Food and Drug Administration issued an Emergency Use Authorization to a covid-19 antibody test developed by the company Cellex. The test looks for two types of antibodies, IgM and IgG, created by the body’s immune system in response to the new coronavirus, known as SARS-CoV-2. The test, which requires blood drawn from a vein, can return results within 15 to 20 minutes, though the testing itself has to be done in a certified laboratory, not at a doctor’s office, unlike some other rapid covid-19 tests.

Yes, that’s right. The classic NASA “worm” logo is back! An image of the revived NASA worm logo was released on Twitter by NASA Administrator Jim Bridenstine as well as press release on the NASA.gov website.

NASA explained that original NASA insignia is an iconic symbol widely recognized in the world. The NASA “meatball” logo as many know it by represented patriotic American colors. A red chevron wing piercing a blue sphere(Planet) with white stars, and an spacecraft orbiting. This “meatball” logo was not easy to reproduce with 1970’s technology so the Federal Design Improvement Program introduced in 1975 a new logo, the “worm.”

Some History about the logo

By the beginning of World War I, the United States lagged behind Europe in airplane technology. On March 3, 1915, Congress founded NACA as an independent government agency in response to the perception that the United States was falling behind in aeronautical technology. NACA would report directly to the President with the purpose to catch up. But technology had evolved, and once again the US was falling behind in technology. Russia launched Sputnik. The space race was being lost.

Following the launch of Sputnik, the United States created NASA to catch up in the space race and pull ahead. In order to help spur on a wave of national enthusiasm in support of the nation’s aeronautical, a logo would be needed. The new agency set out to design a new logo and came up with various options for consideration.

Australian government scientists have begun the first stages of testing for a potential vaccine against the SARS CoV-2 coronavirus, which causes the disease COVID-19. Australia’s national science agency CSIRO said Thursday that testing at a biosecurity facility was expected to take three months. The testing is being undertaken in cooperation with the Coalition for Epidemic Preparedness Innovations (CEPI), a global group that aims to help speedily develop vaccines against emerging infectious diseases.

Australia’s national science agency will test two vaccine candidates over the next three months. It is part of a global race to halt the coronavirus pandemic.

Quantum computers will revolutionize information technology, ushering in an era where certain types of calculations will be performed with almost unimaginable speed. Practical applications will include healthcare disciplines such as molecular biology and drug discovery; big data mining; financial services such as portfolio analysis and fraud detection; and artificial intelligence and machine learning.

The federal government is helping to create an environment in which quantum computing innovation and experimentation can flourish. The National Quantum Initiative Act puts $1.2 billion into the quantum research budgets of the Energy Department, the National Institute of Standards and Technology, NASA and the National Science Foundation. The law also outlines a 10-year plan to accelerate the development of quantum information science and technology applications.

Meanwhile, The White House’s Office of Science and Technology Policy is working to ensure that economic growth opportunities and opportunities for improving the world are baked into quantum policies and systems.

“Our hypersonic testbeds will serve as a catalyst in sparking a renaissance in hypersonic technologies for our government, the commercial sector, and academia,” said W. Jean Floyd, Stratolaunch’s chief executive, in a statement.

This is an interesting, if not wholly unexpected, turn for Stratolaunch. During the last decade, the aerospace community has often collectively scratched its head, wondering how such a large aircraft could be cost-competitive in the hotly contested market to launch small- and medium-sized satellites. And without a dedicated rocket in existence, the company seemed little more than a vanity project for the wealthy Allen. If Stratolaunch served any purpose, the speculation went, it must be to meet some unspecified military need.

There can be no question that the military is interested in hypersonic technology. China, Russia, and the United States are all racing to develop hypersonic missiles, as well as new countermeasure technology as high-speed missiles threaten to penetrate most existing defenses. A Rand Corporation report from 2017 provides more basic information, suggesting, “There is probably less than a decade available to substantially hinder the potential proliferation of hypersonic missiles and associated technologies.”
