How many times have you wished you could play back your dream on your computer or phone? With this new discovery, the technology might be closer than you think.

In a research published last week on the arXiv server, researchers at the National University of Singapore and the Chinese University of Hong Kong reported that they have developed a process capable of generating video from brain scans.

Glutamatergic synaptic input to glioma cells drives brain tumour progression https://lifeboat.com/blog/2023/05/glutamatergic-synaptic-input-to-glioma-cells-drives-brain-tumour-progression https://lifeboat.com/blog/2023/05/glutamatergic-synaptic-input-to-glioma-cells-drives-brain-tumour-progression#respond Tue, 30 May 2023 05:29:31 +0000 https://lifeboat.com/blog/2023/05/glutamatergic-synaptic-input-to-glioma-cells-drives-brain-tumour-progression

Deeply fascinating paper wherein Venkataramani et al. describe how synaptic inputs from neurons onto glioma tumor cells induce electrical activity in the tumors and stimulate their growth and invasiveness. This knowledge could lead to new treatments involving inhibition of the synapses onto gliomas which might provide hope for fighting an otherwise largely incurable form of cancer. #neurobiology #oncology #cancer #medicine


Neurons form glutamatergic synapses with glioma cells in mice and humans, and inhibition of AMPA receptors reduces glioma cell invasion and growth.

German researchers take us a step closer to making nuclear clocks https://lifeboat.com/blog/2023/05/german-researchers-take-us-a-step-closer-to-making-nuclear-clocks https://lifeboat.com/blog/2023/05/german-researchers-take-us-a-step-closer-to-making-nuclear-clocks#respond Tue, 30 May 2023 05:29:01 +0000 https://lifeboat.com/blog/2023/05/german-researchers-take-us-a-step-closer-to-making-nuclear-clocks

The clock’s accuracy would be as high as one second for every 300 billion years.

A collaboration between researchers from various institutes in Germany has brought us a step closer to building the first-ever nuclear clock. In experiments carried out at the European Organization for Nuclear Research (CERN), the researchers measure the radiative decay of thorium-229 nuclear isomer, the first instance of having achieved this feat and a critical component for building nuclear clocks.

For years atomic clocks have been our standard of accuracy when it comes to clocks.

For years atomic clocks have been our standard of accuracy when it comes to clocks. The best optical atomic clocks have a precision rate of 10-18, which is equivalent to an inaccuracy of one second every 30 billion years.

Engineers transform smartphone into blood pressure monitor, thanks to a 10-cent plastic clip https://lifeboat.com/blog/2023/05/engineers-transform-smartphone-into-blood-pressure-monitor-thanks-to-a-10-cent-plastic-clip https://lifeboat.com/blog/2023/05/engineers-transform-smartphone-into-blood-pressure-monitor-thanks-to-a-10-cent-plastic-clip#respond Tue, 30 May 2023 05:28:49 +0000 https://lifeboat.com/blog/2023/05/engineers-transform-smartphone-into-blood-pressure-monitor-thanks-to-a-10-cent-plastic-clip

UC San Diego engineers developed the low-cost clip that enables easy and affordable monitoring in resource-poor communities.

University of California San Diego engineers have created a low-cost clip that makes use of the camera and flash on a smartphone to measure blood pressure at the user’s fingertip.

This innovative clip, which can be produced at scale for as little as 10 cents, has the potential to revolutionize routine blood pressure monitoring and make it available to people in resource-poor regions.

Vision in the Making: Andrew Ng’s Startup Automates Factory Inspection https://lifeboat.com/blog/2023/05/vision-in-the-making-andrew-ngs-startup-automates-factory-inspection https://lifeboat.com/blog/2023/05/vision-in-the-making-andrew-ngs-startup-automates-factory-inspection#respond Tue, 30 May 2023 05:27:38 +0000 https://lifeboat.com/blog/2023/05/vision-in-the-making-andrew-ngs-startup-automates-factory-inspection

Computer vision specialist Landing AI has a unique calling card: Its co-founder and CEO is a tech rock star.

At Google Brain, Andrew Ng became famous for showing how deep learning could recognize cats in a sea of images with uncanny speed and accuracy. Later, he founded Coursera, where his machine learning courses have attracted nearly 5 million students.

Today, Ng is best known for his views on data-centric AI — that improving AI performance now requires more focus on datasets and less on refining neural network models. It’s a philosophy coded into Landing AI’s flagship product, LandingLens.

New York City Sinking Under Weight of Skyscrapers https://lifeboat.com/blog/2023/05/new-york-city-sinking-under-weight-of-skyscrapers https://lifeboat.com/blog/2023/05/new-york-city-sinking-under-weight-of-skyscrapers#respond Tue, 30 May 2023 05:27:13 +0000 https://lifeboat.com/blog/2023/05/new-york-city-sinking-under-weight-of-skyscrapers

New York City is sinking under the weight of its massive buildings, leaving it more vulnerable to rising seas, a new study finds.

Most coastal cities are slowly sinking as the earth beneath them settles and groundwater is drained away. In some metropolises, the weight of large, concrete-and-steel skyscrapers may be hastening this slump, but experts rarely, if ever, account for the mass of large buildings in projections of future sinking.

For the new study, scientists tallied the weight of every building in New York, which they put at 842 million tons, and estimated the downward force of these structures across the city. They found that buildings are leaving a bigger imprint in areas rich in clay than in areas where sand or bedrock predominate.

How long does it take for a body to decompose? https://lifeboat.com/blog/2023/05/how-long-does-it-take-for-a-body-to-decompose https://lifeboat.com/blog/2023/05/how-long-does-it-take-for-a-body-to-decompose#respond Tue, 30 May 2023 05:26:31 +0000 https://lifeboat.com/blog/2023/05/how-long-does-it-take-for-a-body-to-decompose

Once a person is dead, their body usually starts to decay immediately, although a good embalming job can delay decay.
