Women, are you having symptoms such as breathlessness or even chest pain? Then, beware! It can be due to pulmonary hypertension. Here’s all you need to know about the causes, symptoms, risk factors, complications, diagnosis and treatment of pulmonary hypertension.
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.

As we continue to scan the heavens for signs of intelligent life, we must contemplate what it might mean if we are the first civilization to ever arise.

After a long-running probe into TikTok, individual states have started to take action against the social media company over security concerns. CNBC’s Kayla Tausche joins ‘Squawk Box’ with the details.
Tesla CEO Elon Musk recently provided a teaser on what will be happening during the company’s AI Day 2 event this Friday. Considering Musk’s recent comments, it appears that AI Day 2 will be filled to the brim with exciting discussions and demos of next-generation tech.
This is not Tesla’s first AI Day. Last year, the electric vehicle maker held a similar event, outlining the company’s work in artificial intelligence. During the event, Tesla held an extensive discussion on its neural networks, Dojo supercomputer, and humanoid robot, the Tesla Bot (Optimus). Interestingly enough, mainstream coverage of the event later suggested that AI Day was underwhelming or disappointing.
Here’s an interesting thought. What if you were told that everything in your life has already been planned out?
Even stranger, what if your past, present, and future are all happening right at this moment?
An astonishing new theory known as the “block universe” theory claims that time does not actually “flow like a river”, but rather, everything is ever-present.
Amino acids have been found in meteorites, and now an experiment shows how they might have been created by chemical reactions in these space rocks.
