Learning About Ancient Diets From Modern British Teeth
British smiles have an unflattering international image, but a new study has put tartar from infamously bad teeth to good use. By analyzing the teeth of Britons from the Iron Age to the modern day they have leveraged a way to use proteins in tooth tartar to reveal what our ancestors ate.
Dental plaque accumulates on the surface of teeth during life and is mineralized by components of saliva to form tartar or "dental calculus", entombing proteins from the food we eat in the process. Proteins are hearty molecules and can survive in tartar for thousands of years. That's good for science.

Global Warming Could Ruin The Internet
At the Applied Networking Research Workshop, a meeting of the Association for Computing Machinery, the Internet Society and the Institute of Electrical and Electronics Engineers, one group claimed critical communications infrastructure, buried fiber optic cable, could be submerged by rising seas in as soon as 15 years.
They estimate that by the year 2033 more than 4,000 miles of buried fiber optic conduit will be underwater and more than 1,100 traffic hubs will be surrounded by water. The most susceptible U.S. cities are predictably New York, Miami and Seattle.

Even The Smell Of Coffee Boosts Math Performance
Coffee is the official drink of Science, Technology, Engineering, and Math (STEM), so much so that a new study finds that it's downright Pavlovian. Even the smell of coffee boosts numerical performance.
In their experiment, scholars administered a 10-question Graduate Management Aptitude Test (GMAT - the analytical portion of a computer adaptive test required by many graduate schools) in a computer lab to about 100 undergraduate business students, divided into two groups. One group took the test in the presence of an ambient coffee-like scent, while a control group took the same test - but in an unscented room.

Why Pot Gives You The Munchies Identified In Animal Studies
It's no secret that marijuana usage leads to hunger, it even has a colloquial name - "the munchies." But understanding the neuroscience of that that could also help people who lose their appetites during illness.

Hunter Gatherers Baked Their Own Bread 14,000 Years Ago - 4,000 Years Before Agriculture
Some 4,000 years before domesticated agriculture, hunter-gatherers baked their own bread, according to a discovery at an archaeological site in northeastern Jordan.
Researchers have discovered the charred remains of a flatbread baked around 14,400 years ago, the oldest direct evidence of bread found to date, predating the advent of agriculture by at least 4,000 years. The findings suggest that bread production based on wild cereals may have encouraged hunter-gatherers to cultivate cereals, and thus contributed to the agricultural revolution in the Neolithic period.

New Class Of Commercial Herbicide Is All Natural - But Discovered Using Science
Nature is not just out to kill us, it is out to kill itself, in the interest of surviving over the long term. That is why even the most wholesome backyard organic garden is a hotbed of combat between plants and unseen microorganisms in the soil fighting for space to grow.
To defeat a plant, a microbe might produce and use toxic chemicals - but then the microbe also needs immunity from its own poisons. The genes that create protective shield in microorganisms could become a new, highly effective weed killer and the first new class of commercial herbicides in more than 30 years.

Bees: It's The Viruses That Are The Problem
While environmentalists raise millions of dollars insisting they will get targeted pesticides (e.g. neonicotinoids) banned to save bees that aren't really in peril, science is looking at things which do actually put bees at risk.
At the top of the list is not pesticides, it's nature. An international team has discovered evidence of 27 previously unknown viruses in bees, which could help scientists design strategies to prevent the spread of viral pathogens among these important pollinators.

A Beautiful New Spectroscopy Measurement
What is spectroscopy ?
(A) the observation of ghosts by infrared visors or other optical devices
(B) the study of excited states of matter through observation of energy emissions
If you answered (A), you are probably using a lousy internet search engine; and btw, you are rather dumb. Ghosts do not exist.
Otherwise you are welcome to read on. We are, in fact, about to discuss a cutting-edge spectroscopy measurement, performed by the CMS experiment using lots of proton-proton collisions by the CERN Large Hadron Collider (LHC).

Intermittent Fasting Fad May Increase Diabetes Risk
Intermittent fasting - fasting every other day - is guaranteed to lose weight in the short term, because it's a crash diet.
But like lots of other fad diets, the people selling books about it are basing their speculation on animal models and an unrealistic amount of optimism. In biological reality, intermittent fasting impairs the action of sugar-regulating hormone, insulin, which may increase diabetes risk.
Findings presented in the spring at at the European Society of Endocrinology annual meeting, suggest that fasting-based diets may be associated with long-term health risks and careful consideration should be made before starting this fad program - or any fad diet. Energy balance is the only known way to lose weight.

Maybe The Oumuamua Asteroid Is Really A Comet
The asteroid Oumuamua ("scout from the distant past" in Hawaiian) was discovered on October 19, 2017 by astronomers at thr Pan-STARRS1 survey when it came close to Earth's orbit, within the orbit of Mercury, about a month after its closest approach to the Sun It was called an asteroid - but it may be a comet.
Why the confusion? There are more data about its trajectory. Oumuamua was unlike any asteroid or comet observed before. It sped past the Sun, approaching from "above" the plabe of the planets on a highly inclined orbit, moving fast enough (70,800 miles per hour as of July 1, 2018) to escape the Sun's gravitational pull and eventually depart our Solar System.
