In 1992, scientists found drugs such as cocaine, hashish, and nicotine in some Egyptian mummies. These mummies came to be known as the “cocaine mummies.”
Traces of the drugs were found in the hair and skin of the mummies. Initially, scientists thought that this was a result of contamination and that perhaps improper techniques had been used to analyze the mummy.
There are serious indications from attempts to create a quantum theory of gravity that time must disappear completely from the description of the quantum universe. This has been known since 1967, when DeWitt discovered the Wheeler-DeWitt equation. I shall argue that this forces us to conceive explanation and causality in an entirely new way. The present can no longer be understood as the consequence of the past. Instead, I shall suggest that one may have to distinguish possible presents on the basis of their intrinsic structure, not on the basis of an assumed temporal ordering. If correct, this could have far-reaching implications. Hitherto, because the present has always been interpreted as the lawful consequence of the past, science has made no attempt to answer ‘Why’ questions, only ‘How’ questions. But if there is no past in the traditional sense, we must consider things differently. Thus, if we eliminate time, we may even be able to start asking “Why” questions.
Specification of a point and tangent vector in conformal superspace (CS) determines a slab of spacetime in CMC foliation and unique curve in CS. Almost perfect implementation of Mach’s principle because local inertial frames, local proper distance and local proper time all emergent and determined by the universe’s shape and shape velocity. The Mystery: Shape velocity, as opposed to shape direction, is last vestige of Newton’s absolute space and time. Responsible for expansion of the universe and perhaps perfect transformation theory in quantum theory of the universe.
Panpsychism is a disruptive theory put forward by some philosophers and neuroscientists. It proposes that human consciousness is only one of many forms of consciousness in…

A good night’s sleep can work wonders for both mind and body. But what is it that determines how much we need to sleep, and what can cause us to sleep more deeply?
In a new study, researchers from the University of Tsukuba have now provided some answers, revealing a signaling pathway within brain cells that regulates the length and depth of sleep.
“We examined genetic mutations in mice and how these affect their patterns of sleep,” says senior author of the study, Professor Hiromasa Funato. “We identified a mutation that led to the mice sleeping much longer and more deeply than usual.” The researchers found that this was caused by low levels of an enzyme called histone deacetylase 4 (HDAC4), which is known to suppress the expression of target genes.
One key objective of electronics engineering research is to develop computing devices that are both highly performing and energy-efficient, meaning that they can compute information quickly while consuming little power. One possible way to do this could be to combine units that perform logic operations and memory components into a single device.
So far, most computing devices have been made up of a processing unit and a physically separate memory component. The creation of a device that can efficiently perform both these functions, referred to as a logic-in-memory architecture, could help to significantly simplify devices and cut down their power consumption.
While a few of the logic-in-memory architectures proposed so far achieved promising results, most existing solutions come with practical limitations. For instance, some devices have been found to be unstable, unreliable or only applicable to specific use cases.
Tumors are three-dimensional phenomena, but so far we have been using 2D imagery to scan and study them. With the advancement of virtual reality in recent years, professor and director at Cancer Research UK Cambridge Institute Greg Hannon saw an opportunity to advance cancer research by incorporating 3D imaging and VR technology.
In 2017, his IMAXT team (Imaging and Molecular Annotation of Xenografts and Tumors) received a £20 million grant from Cancer Grand Challenges to develop VR software that could map tumours at an unprecedented level of detail. In the last few years, the project welcomed interdisciplinary and international collaborations between scientists and artists who created and tested the technology on breast cancers.
