People like Nathan have found out first hand that they can. You may have also seen scientists and doctors talking about mycotherapy for serious chronic conditions like cancer and HIV. That’s because many conditions thought of as diseases really have the same cause– an immune system that was unbalanced and compromised by environmental factors or diet.

Certain foods we eat are inflammatory, they boost problematic cells in our body called TH2 cytokines, which cause inflammation, and these cells can cause allergic reactions, auto-immune conditions, and weaken the cancer-fighting TH1 cytokines. When the TH1 cytokines are weakened by inflammatory foods, cancer is allowed to thrive and grow and spread.

But our bodies naturally have the ability to fight diseases and cancers, that’s what our immune system’ does.

The cells responsible for finding and removing cancer in our body, the TH1 cytokines, do this amazingly– but inflammatory foods and environments shut them down and prevent these natural cells from doing their jobs and killing cancerous cells quickly.

Scientists at Nanyang Technological University, Singapore (NTU Singapore) have found that a stress response in cells, when ‘switched on’ at a post-reproductive age, could be the key to slowing down aging and promoting longevity.

Longevity. Technology: In lab experiments on a type of roundworm that shares similarities with humans – paging C elegans – the NTU Singapore team found that switching on this stress response in aged worms by feeding them a high-glucose diet extended their lifespan as compared with worms fed a normal diet.

Publishing today in Nature Communications, the NTU team say this is the first time a link between this stress response and aging has been uncovered.

Patients with a specific form of age-related macular degeneration (AMD), a leading cause of blindness in the United States, are also highly likely to have either underlying heart damage from heart failure and heart attacks, or advanced heart valve disease, or carotid artery disease associated with certain types of strokes, according to a new study from New York Eye and Ear Infirmary of Mount Sinai.

This research, published November 17 in BMJ Open Ophthalmology, is the first to identify which types of high-risk cardiovascular and carotid artery disease are linked to the eye disorder. The findings could prompt increased screening to save vision, diagnose undetected heart disease, and prevent .

“For the first time, we have been able to connect these specific high-risk cardiovascular diseases to a specific form of AMD, the one with subretinal drusenoid deposits (SDDs),” explains lead author R. Theodore Smith, MD, Ph.D., Professor of Ophthalmology at the Icahn School of Medicine at Mount Sinai.

Spectra from quasars suggest that intergalactic gas may have been heated by a form of dark matter called dark photons.

Dense gas clouds across the Universe absorb light from distant quasars, producing absorption lines in the quasar spectra. A new study shows that the larger-than-predicted widths of these lines from nearby gas clouds could result from a form of dark matter called dark photons [1]. These particles could heat the clouds, leading to a widening of the absorption lines. Other explanations of the broadening—based on more conventional heating sources—have been proposed, but if the dark-photon mechanism is at work, it might also cause heating in low-density clouds from earlier epochs of the Universe. Researchers are already planning to test this prediction.

When viewing the spectrum of a distant quasar, astronomers often observe absorption lines coming from the intervening clouds of gas. The most prominent absorption line is the Lyman-alpha line of hydrogen. Indeed, some quasar spectra have a “forest” of Lyman-alpha lines, with each coming from a cloud at a different distance from our Galaxy (or different epochs). By examining the widths, depths, and other details of the line shapes, researchers can extract information about the density, the temperature, and other features of the clouds. This information can be compared with the results of cosmological simulations that try to reproduce the clumping of matter into galaxies and other large-scale structures.

Asphaltenes, a byproduct of crude oil production, are a waste material with potential. Rice University scientists are determined to find it by converting the carbon-rich resource into useful graphene.

Muhammad Rahman, an assistant research professor of materials science and nanoengineering, is employing Rice’s unique flash Joule heating process to convert asphaltenes instantly into turbostratic (loosely aligned) graphene and mix it into composites for thermal, anti-corrosion and 3D-printing applications.

The process makes good use of material otherwise burned for reuse as fuel or discarded into tailing ponds and landfills. Using at least some of the world’s reserve of more than 1 trillion barrels of as a feedstock for graphene would be good for the environment as well.

Two-dimensional materials, which consist of just a single layer of atoms, can be packed together more densely than conventional materials, so they could be used to make transistors, solar cells, LEDs, and other devices that run faster and perform better.

One issue holding back these next-generation electronics is the heat they generate when in use. Conventional electronics typically reach about 80 degrees Celsius, but the in 2D devices are packed so densely in such a small area that the devices can become twice as hot. This can damage the device.

This problem is compounded by the fact that scientists don’t have a good understanding of how 2D materials expand when temperatures rise. Because the materials are so thin and optically transparent, their thermal expansion coefficient (TEC)—the tendency for the material to expand when temperatures increase—is nearly impossible to measure using standard approaches.

Engineers at Caltech and the University of Southampton in England have collaboratively designed an electronics chip integrated with a photonics chip (which uses light to transfer data)—creating a cohesive final product capable of transmitting information at ultrahigh speed while generating minimal heat.

Though the two– sandwich is unlikely to find its way into your laptop, the new design could influence the future of data centers that manage very high volumes of data communication.

“Every time you are on a video call, stream a movie, or play an online video game, you’re routing data back and forth through a to be processed,” says Caltech graduate student Arian Hashemi Talkhooncheh, lead author of a paper describing the two-chip innovation that was published in the IEEE Journal of Solid-State Circuits on November 3.
