3D tumors that disintegrate within a few days thanks to the action of a well-known omega-3 (DHA, found mainly in fish) – this is a promising discovery. Hungry for fatty acids, tumor cells in acidosis gorge themselves on DHA but are unable to store it correctly and literally poison themselves. The result? They die.

So-called “good fatty acids” are essential for human health and much sought after by those who try to eat healthily. Among the Omega-3 fatty acids, DHA or docosahexaenoic acid is crucial to brain function, vision and the regulation of inflammatory phenomena.

In addition to these virtues, DHA is also associated with a reduction in ...

Consuming large amounts of daily caffeine may increase the risk of glaucoma more than 3X for those with a genetic predisposition to higher eye pressure according to an international, multi-center study. The research led by the Icahn School of Medicine at Mount Sinai is the first to demonstrate a dietary — genetic interaction in glaucoma. The study results published in the June print issue of Ophthalmology may suggest patients with a strong family history of glaucoma should cut down on caffeine intake.

The study is important because glaucoma is the leading cause of blindness in the United States. It looks at the impact of caffeine intake on glaucoma, and intraocular pressure (IOP) which is pressure inside the eye...

Acoustic waves in gases, liquids, and solids usually travel at an almost constant speed of sound. So-called rotons are an exception: their speed of sound changes significantly with the wavelength, and it is also possible that the waves travel backwards. Researchers at Karlsruhe Institute of Technology (KIT) are studying the possibilities of using rotons in artificial materials. These computer-designed metamaterials, produced by ultra-precise 3D laserprinting, might be used in the future to manipulate or direct sound in ways that have never been possible before. A report on the researchers’ work has been published in Nature Communications.

Rotons are quasiparticles, whic...

At night, seven-year-old Miguel likes talking to his father Cesar Rubio about planets and stars. “I try to nurture that,” says Rubio, a machinist in Pomona, California, who makes parts for mining and power generation equipment.

Now, the boy’s father can claim he helped discover planets, too. He is one of thousands of volunteers participating in Planet Hunters TESS, a NASA-funded citizen science project that looks for evidence of planets beyond our solar system, or exoplanets...
