Gender bias against women is nothing new, especially when it comes to seeking venture capital financing for business start-ups,  but in modern crowdfunding -  where a "crowd" of amateur investors make small investments in new companies - culture it is just the opposite; female entrepreneurs are considered more trustworthy.

There are numerous ways to get a business off the ground. Friends and family financing, private equity, bank financing, venture capital, but the difficult road for entrepreneurs has meant that business leaders should be tough - and that has meant more masculine.

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. 
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. 
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.
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. 
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.
