Both 2020TD and 2020TU2 have not been included in the ESA’s Risk List
2020TO2 will make its next close approach two years from now
Two giant near-Earth asteroids will make their closest approach this Wednesday with Earth, with each about four times the size of The Great Sphinx of Giza in Egypt.
Asteroids 2020TD and 2020TU2 are on currently on their way to zip by the Earth on Oct. 14, Wednesday. The first of the two to pass by is 2020TD at 10:14 a.m. EDT. Considered an Apollo asteroid, this near-Earth asteroid has an earth-crossing orbit. At a certain point, its orbit makes contact with that of the Earth’s, making the chances of a possible impact between the two significantly higher. According to NASA’s Center for Near-Earth Object Studies, 2020TD will have a diameter of about 262 feet (80
A research team at LKS Faculty of Medicine, The University of Hong Kong (HKUMed) discovered that exosomes derived from V?2-T cells (Vδ2-T-Exos) can effectively control Epstein-Barr virus-associated tumours and induce T-cell anti-tumour immunity. The novel findings of Vδ2-T-Exos provide insights into new therapeutic approach for Epstein-Barr virus (EBV)-associated tumours. The ground-breaking findings have been published in the leading academic journal, Science Translational Medicine.
EBV infects about 95% of the human population and causes more than 200,000 cases of cancer each year and that around 2% of all cancer deaths are due to EBV-attributable malignancies. EBV-associated tumours include Burkitt lymphoma, Hodgkin lymphoma, nasopharyngeal carcinoma, gastric tumour and post-transplant lymphoproliferative disease, etc. Current treatment options for EBV-associated tumours are limited with considerably unwanted off-target toxicities and incomplete effectiveness for relapsed or refractory disease. V?2-T cells are innate-like T cells with anti-tumour potentials against EBV-associated tumours. Unfortunately, its clinical translation is limited
SpaceX CEO Elon Musk’s Tesla roadster made its first close approach to Mars on Wednesday.

The roadster, “driven” by a mannequin dubbed “Starman” wearing a spacesuit, was part of a dummy payload attached to the second stage of a SpaceX Falcon Heavy Rocket that launched in 2018.
SpaceX tweeted yesterday that the vehicle made its first close approach with Mars, coming within 5 million miles of the planet.
“It’s a long distance,” Jonathan Dowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics, told CNN. “Mars would appear about 1/10 the diameter of the Moon, so small but not a point.”
Dowell tracked the rocket using NASA’s Jet Propulsion Laboratory Horizons system, which has an accurate trajectory calculated from the Falcon 9’s initial orbit as it left Earth. He says that it is in elliptical orbit around the
The US State Department is offering whistleblower rewards to stop foreign hacking operations that … [+] affect elections. (Photo by Sina Schuldt/picture alliance via Getty Images)

FBI Director Christopher Wray’s recent warning that Russia is seeking to disrupt and influence US elections underscores the vulnerability of our elections and political campaigns to foreign influence and hacking.
As is increasingly the case, whistleblowers likely will be a vital first line of defense.
Recognizing that, the State Department has launched a promising way to turn the tables on foreign hacking operations and disrupt the disrupters: It is offering whistleblower rewards of up to $10 million to those who can identify or provide the location of individuals who are working at the behest of foreign governments to interfere with a national, state or local election.
Incentivizing knowledgeable insiders to report wrongdoing by offering whistleblower rewards has long been
Mars will bright and beautiful in the October 2020 night sky.

Forget Halloween. This October is all about the glory of Mars, as the glimmering red planet puts on a show in the night sky. You can enjoy Mars as a bright point of light all month long, but there are two special dates to mark on your calendar: Oct. 6 when the planet makes a close approach to Earth, and Oct. 13, when it will be in opposition.
Spotting Mars
Mars has a reputation as the “red” planet, but its color in the night sky is a little more on the Halloween side of the spectrum. It appears as a bright orange-red dot to the naked eye, like a little spot of glittering rust.

On October 6, 2020, Mars makes its closest approach to Earth until 2035.
Earth orbits in a nearly circular path, completing a revolution every 365 days. Mars orbits in the … [+] same direction, but in a more elliptical and slower, more distant orbit, completing a revolution every 687 days. When these two factors are combined, Earth makes its “closest approach” to Mars every 780 days: a little more than 2 Earth years.

We’ve tracked the rise of QAnon-affiliated political candidates, including Marjorie Taylor Greene, a Georgia Republican who is currently on track to be elected to Congress in November. And we’ve tried to debunk QAnon’s most outrageous and dangerous claims — like the obviously false allegation that Hillary Clinton and other Democrats were literally killing and eating children in order to harvest a life-extending chemical from their blood. In the lead-up to the election, The Times has rolled out a feature called “Daily Distortions” aimed partly at debunking misinformation that has gone viral or caused harm offline.
QAnon is clearly a political story, and a story about how internet platforms have amplified dangerous misinformation and conspiracy theories. At the same time, I’m a former religion reporter, and I’m fascinated by the culture of QAnon. It’s not just a conspiracy theory — it’s a real-time, interactive media-making collaboration that gives people community, alleviates
NASA’s Parker Solar Probe is set to break a record tomorrow, becoming the closest-ever human-made object to the sun. The probe will break its own previous record, coming within 8.4 million miles of the sun’s surface and traveling at 289,927 miles per hour.
This will be the probe’s sixth flyby of the sun since it was launched in 2018. As it orbits around the sun, it gets gradually closer and closer with each pass, and over the summer it got an extra boost by using the gravity of Venus to adjust its trajectory. In July this year, the probe came within just 518 miles of the surface of Venus, and the gravitational assist from this maneuver allowed the probe to get 3.25 million miles closer to the sun than its last pass in June.
This flyby will also be the first time that the probe will pass within 0.1 AU
In 1921, Albert Einstein received the Nobel Prize in physics for the discovery that light is quantized, interacting with matter as a stream of particles called photons. Since these early days of quantum mechanics, it is known that photons also possess momentum. The photon’s ability to transfer momentum was used in a novel approach by scientists of the Max Born Institute, Uppsala University, and the European X-Ray Free-Electron Laser Facility to observe a fundamental process in the interaction of x-rays with atoms. The detailed experimental and theoretical results are reported in the journal Science.
Absorption as well as emission of a photon by an atom are fundamental processes of the interaction of light with matter. Much rarer are processes in which several photons simultaneously interact with one atom. The availability of intense laser beams since the 1960s has led to the development of “nonlinear optics,” which observes and utilizes such
