BlenderBot 2.0 is better at conducting more extended, more knowledgeable, and factually consistent conversations over multiple sessions than the existing state-of-the-art chatbot. BlenderBot’s improved conversational abilities have made it a serious contender for artificial intelligence research.

The AI model takes the information it gets from conversations and stores them in long-term memory. The knowledge is stored separately for each person they speak to, which ensures that new information learned in one conversation can’t be used against another.

This model can read and respond in real-time, making it an excellent tool for keeping up with current events. It can scan the internet for new information to have a more up-to-date conversation.

Facepalm: Microsoft is once again advising its customers to disable Windows print spooler, after a new vulnerability that allows hackers to execute malicious code on machines has emerged. While a patch fixing the flaw will be released in due course, the most effective workaround currently on the table is to stop and disable the print spooler service entirely.

This is the third print spooler vulnerability to emerge in just five weeks. While a critical flaw was originally identified and patched in June, a similar flaw – dubbed PrintNightmare – came to light shortly after and was subsequently patched (with mixed success).

The emergence of this new vulnerability is frustrating news for Microsoft and its users.

For the first time, space weather disruptions triggered by the Sun were measured using pulsars with the help of the upgraded Giant Metrewave Radio Telescope (uGMRT) in Pune.

Usually weighing 1.5 times more than the sun, pulsars are massive stars which rotate at a very high speed (up to 600 rotations per minute) and emit periodic radio flashes. Pulsars are considered the most accurate clocks in the universe and scientists accurately predict their flashes.

Using uGMRT, astronomers record pulsar radio flashes once every 14 days and it was during one such observation in February 2019 that they chanced upon Coronal Mass Ejection (CME). One such disruption, resultant CME, was confirmed based on the abnormally-delayed radio signals received from PSRJ2145 – 0750, the pulsar source under uGMRT observation, on February 23, 2019.

He has not been able to speak since 2003, when he was paralyzed at age 20 by a severe stroke after a terrible car crash.

Now, in a scientific milestone, researchers have tapped into the speech areas of his brain — allowing him to produce comprehensible words and sentences simply by trying to say them. When the man, known by his nickname, Pancho, tries to speak, electrodes implanted in his brain transmit signals to a computer that displays his intended words on the screen.

His first recognizable sentence, researchers said, was, “My family is outside.”

Circa 1999 could lead to a sorta room temperature hydrogen fill up.


Masses of single-walled carbon nanotubes (SWNTs) with a large mean diameter of about 1.85 nanometers, synthesized by a semicontinuous hydrogen arc discharge method, were employed for hydrogen adsorption experiments in their as-prepared and pretreated states. A hydrogen storage capacity of 4.2 weight percent, or a hydrogen to carbon atom ratio of 0.52, was achieved reproducibly at room temperature under a modestly high pressure (about 10 megapascal) for a SWNT sample of about 500 milligram weight that was soaked in hydrochloric acid and then heat-treated in vacuum. Moreover, 78.3 percent of the adsorbed hydrogen (3.3 weight percent) could be released under ambient pressure at room temperature, while the release of the residual stored hydrogen (0.9 weight percent) required some heating of the sample.

Thanks to Stanford researchers, there might be a new recipe for hydrogen fuel: saltwater, electrodes and solar power. The researchers have developed a proof-of-concept for separating hydrogen and oxygen gas from seawater via electricity. It’s far cheaper than the current methods, which rely on creating hydrogen fuel from purified water.

Breaking up a substance like water to create hydrogen and oxygen is called electrolysis and is a scientific technique centuries old. It was first codified by British scientific legend Michael Faraday, whose two laws of electrolysis from 1834 still guide scientists today. With a power source connecting to two water-based electrodes, scientists can get hydrogen bubbles to come out of an end called an cathode, while oxygen comes out of an end called an anode.

That works fine for fresh water, but saltwater is trickier because of its ability to corrode electrodes with chloride, which would limit a system’s lifespan. The trick for Hongjie Dai, a professor of chemistry at Stanford, and his team was a change in materials.
