Unknown risks and the collapse of human civilisation: A review of the AI-related scenarios

Science and technology have experienced a great transition, a development that has shaped all of humanity. As progress continues, we face major global threats and unknown existential risks even though humankind remains uncertain about how likely unknown risks are to occur. This paper addresses five straightforward questions: (1) How can we best understand the concept of (existential) risks within the broader framework of known and unknown? (2) Are unknown risks worth focusing on? (3) What is already known and unknown about AI-related risks? (4) Can a super-AI collapse our civilisation? Furthermore, (5) how can we deal with AI-related risks that are currently unknown? The paper argues that it is of high priority that more research work be done in the area of ‘unknown risks’ in order to manage potentially unsafe scientific innovations. The paper finally concludes with the plea for public funding, planning and raising a general awareness that the far-reaching future is in our own hands

Anti-inflammatory activity of extracts of root bark of Securidaca longipedunculata fres (polygalaceae)

The effect of extract and fractions of the root bark of Securidaca longipedunculata Fres (Polygalaceae) on acute inflammation was evaluated. Solvent extraction yielded the crude methanol extract (ME) while solvent–guided extraction yielded a petroleum ether fraction (PF) and methanol fraction (MF). The extract and fractions inhibited topical edema induced by xylene in the mouse ear. In the systemic edema of the rat paw, the methanol extract (ME) and methanol fraction (MF) significantly (P PF > ME. Phytochemical tests showed that ME and MF tested positive for carbohydrates, reducing sugars, glycosides, flavonoids, terpenoids, sterols and saponins while PF gave positive reaction for resins only.Acute toxicity test for ME in mice established an i.p and p.o LD50 of 11 and 282 mg/kg respectively.

Research Paper - ANTI-INFLAMMATORY ACTIVITY OF EXTRACTS OF ROOT BARK OF SECURIDACA LONGIPEDUNCULATA FRES (POLYGALACEAE)

The effect of extract and fractions of the root bark of Securidaca longipedunculata Fres (Polygalaceae) on acute inflammation was evaluated. Solvent extraction yielded the crude methanol extract (ME) while solvent guided extraction yielded a petroleum ether fraction (PF) and methanol fraction (MF). The extract and fractions inhibited topical edema induced by xylene in the mouse ear. In the systemic edema of the rat paw, the methanol extract (ME) and methanol fraction (MF) significantly (P<0.05) suppressed the development of paw edema induced by egg albumin in rats while the petroleum ether fraction (PF) was devoid of such activity.Ulcerogenic assay in rats indicated that the extract and fractions exhibited varying degrees of gastric irritation in rats in the order of magnitude: MF > PF > ME. Phytochemical tests showed that ME and MF tested positive for carbohydrates, reducing sugars, glycosides, flavonoids, terpenoids, sterols and saponins while PF gave positive reaction for resins only.Acute toxicity test for ME in mice established an i.p and p.o LD50 of 11 and 282 mg/kg respectively

Evaluation of the Antiulcer Properties of Pseudocedrela kotschyi Stem Bark Extract

Aqueous stem bark extract of Pseudocedrela kotschyi, Harms (Meliaceae) was investigated for antiulcer activity. The extract neither contracted nor relaxed the isolated guinea pig ileum. It however, inhibited the contraction evoked by acetylcholine and histamine in a doserelated manner. Gastrointestinal motility in mice was significantly (

The extract showed a biphasic effect on isolated smooth muscle. Lower concentration or extract caused contraction, while higher concentrations produced relaxation. The contractile phase was attenuated by atropine, while relaxant phase attenuated histamine induced contraction or guinea pig ileum. The extract also exhibited a dose-dependent inhibition of gastrointestinal motility.
