The tidal disruption event ripped apart the star so a black hole could feast.
Year 2017 This is essentially the mechanism for plant immortality.
RNA-directed DNA methylation (RdDM) activity in the Arabidopsis thaliana male sexual lineage that regulates gene expression in meiocytes. Loss of sexual-lineage-specific RdDM causes mis-splicing of the MPS1 gene (also known as PRD2), thereby disrupting meiosis. Our results establish a regulatory paradigm in which de novo methylation creates a cell-lineage-specific epigenetic signature that controls gene expression and contributes to cellular function in flowering plants.

Spacecrafts in dozens of sci-fi movies like Star Trek use antimatter propulsion systems to travel at unimaginably high speeds by warping spacetime. By using them, traveling to different planets and stars is significantly more efficient and quick. However, is it possible to make this sci-fi idea a reality? If so, how and when will we be able to use them? Letâs take a closer look.
Before we discuss what antimatter spacecraft are, letâs first take a look at what antimatter is. Antimatter is the opposite of normal matter. More specifically, the subatomic particles of antimatter have properties opposite to those of normal matter. The electrical charge of those particles is reversed. Meaning, once they collide with âregularâ matter or the matter we know today, they react and cause an explosion in an instant. Due to this, antimatter is extremely rare since it gets obliterated with nearly everything made of matter.
An antimatter rocket is a proposed class of rockets that use antimatter as their main power source. The advantage to this class of rocket is that a large portion of the rest mass of a matter-antimatter mixture may be converted to energy, allowing antimatter rockets to have a far greater energy density than any other rocket that uses regular fuel.
The team replicated different patterns of materials and found arrangements that would let water through more easily.
Artificial intelligence (AI) has been found to be useful in the creation of water filter materials and can quicken the process involved in making them, according to a study published today (Nov .30) in the journal ACS Central Science.
Creating a novel water purification system
From daily household faucet attachments to room-sized industrial systems, filter systems are used in a variety of items. However, it is difficult for current filtration membranes to filter water if the water is extremely dirty or has small, neutral molecules, such as boric acid, an insecticide used on crop plants.
The partnership aims at building infrastructures, such as landing pads, habitats, and roads on the lunar surface.
In a quest to find practical solutions to build sustainable structures on the moon, NASA has furthered its partnership with ICON, a construction technologies company based in Austin, Texas. The firm is known for building the first-ever habitable 3D-printed home in the United States in 2018.
The space agency has now awarded a $57.2 million contract to ICON to devise solutions that âcould help build infrastructure such as landing pads, habitats, and roads on the lunar surface,â according to the press release.
The organization says the machines would only be used in extreme situations where lives are at stake.
Supervisors in San Francisco voted Tuesday to allow city police to use potentially lethal remote-controlled robots in emergency situations, according to a report by Mission Local.
A dystopian future?

The vote was eight for three against, with opponents saying the move would lead to the further dangerous and unwanted militarization of a police force already too aggressive with minorities.
Artificial intelligence would be used to detect changes in the vocals of each patient after a laryngectomy.
Researchers from Kaunas University of Technology Faculty of Informatics (KTU IF) and Lithuanian University of Health Sciences (LSMU) in Lithuania have created a new substitute voice evaluation index that can detect pathologies in patientsâ voices more quickly and efficiently. Voice pathologies include a variety of disorders such as growths on the vocal cords, spasms, swelling or paralysis in the vocal cords.
AI could be used to determine changes in voice after laryngectomy.
Laryngectomy is a surgery that requires the removal of the larynx.

âFor some, the voice changes only slightly, while for others, it can be a life-changing situation. Imagine calling someone on the phone, emergency services, police, etc. â and the one youâre calling does not understand anything. Or even not hear you â as the phoneâs noise removal system will cut it out,â said Dr. Rytis Maskeliunas, professor with the Department of Multimedia Engineering, Faculty of Informatics and chief researcher at Kaunas University of Technology Faculty of Informatics.
It is the first ever commercial partnership between Google Health and the medical company iCAD.
Google recently announced that it licensed its AI research prototype to a medical company called iCAD. The AI research model can be used for breast cancer screening. iCAD is a company that creates innovative medical equipment for cancer detection.
ICAD made the announcement about the collaboration yesterday, Nov. 28, on its website.
It is the first time ever that Google Health has licensed this specific artificial intelligence technology in a commercial partnership for breast cancer screening and personalized risk assessment of the disease, to iCAD.

Interesting Engineering sighted âSpot the Dogâ with construction group Balfour Beatty. Naturally, we had a chat with one of their technicians.
âSpot the dog,â Balfour Beattyâs first robotic employee, was sighted by Interesting Engineering (IE) at the âBrooklands Science Summer School eventâ yesterday (Nov. 29).
Spot delivers CAT designs for derelict buildings and nuclear power plants.
