Caterpillar found to eat shopping bags, suggesting biodegradable solution to plastic pollution

Scientists have found that a caterpillar commercially bred for fishing bait has the ability to biodegrade polyethylene: one of the toughest and most used plastics, frequently found clogging up landfill sites in the form of plastic shopping bags.


Scientists discover gene that blocks spread of colon cancer

Researchers from RCSI (Royal College of Surgeons in Ireland) and the University of Nice, France, have discovered the function of a gene called KCNQ1 that is directly related to the survival of colon cancer patients. The gene produces pore-forming proteins in cell membranes, known as ion channels. The finding is an important breakthrough towards the development of more effective therapies for colon cancer and new diagnostics that will provide a more accurate prognosis for colon cancer patients. The research is published this week in the prestigious journal Proceedings of the National...

Immunity against melanoma is only skin deep

In a newly published study, researchers at Dartmouth's Norris Cotton Cancer Center find that unique immune cells, called resident memory T cells, do an outstanding job of preventing melanoma. The work began with the question of why patients with melanoma who develop the autoimmune disease called vitiligo, have such a good prognosis. Vitiligo is an autoimmune skin condition against normal healthy melanocytes, which causes the loss of skin pigmentation in blotches. Using mouse models of melanoma and vitiligo, the research team found that resident memory T cells permanently reside in...

Are We Living in a Computer Simulation? Elon Musk Thinks So.

Elon Musk and others, including astrophysicist Neil deGrasse Tyson, believe that there is a significant chance that our world is just an elaborate simulation created by an advanced civilization. However, it seems just as likely that they are wrong.


The Missing Universe: CERN Has Started Searching for "Dark Photons"

Dark matter seems to outweigh visible matter roughly six to one, making up about 27% of the universe. Physicists from CERN now believe there's a fifth universal force that rules the behavior of dark matter, and is transmitted by a particle called the dark photon.


The Military Is Two Years Away From Unleashing Its Real-Life Iron Man Suit

The Department of Defense is two years away from unveiling an Iron Man-like suit. Known as the Tactical Light Operator Suit (Talos), it can repel bullets, help lift heavy objects, and provide lifesaving oxygen. The suit also comes with 3D audio; heating and cooling systems; and embedded computers.

COLLIDING BLACK HOLES MAY DISRUPT THE SPACE-TIME CONTINUUM IN 100,000 YEARS

In a galaxy far, far away, two black holes are dancing around each other, drawn together by each others’ immense gravity. Eventually the two may collide, triggering a blast with the power of 100 million star explosions.


That won’t happen for at least 100,000 years, and its effect on Earth will be subtle. The black hole duo is located about 3.5 billion light-years away, but the encounter will send out ripples in the space-time continuum that will allow scientists to better study the theory of general relativity.

Scientists conduct most precise test to date of light speed finding Speed of Light is indeed Constant

Physicists have reported the most accurate test to date of Lorentz symmetry for photons by looking for variations in the speed of light, but found no violations. The study, by Moritz Nagel at the Humboldt-University of Berlin, Stephen Parker at The University of Western Australia, and their co-authors, is published in a recent issue of Nature Communications.
