Laboratory Equipment’s scientist of the week is Kay Tye from MIT. She and a team found that the desire for sugar and the urge to eat healthy foods are on separate neural circuits. This means that it might be possible to reduce the urge to eat unhealthy foods without impacting the drive to eat healthily when hungry.
Internet service providers like Comcast, Verizon, AT&T, Sprint and T-Mobile now must act in the "public interest" when providing a mobile connection to your home or phone, under rules approved today by a divided FCC. The plan, which puts the Internet in the same regulatory camp as the telephone, represents the biggest regulatory shakeup to the industry in almost two decades.
There are few drinks as iconic as a pint of Guinness. It might, therefore, surprise beer connoisseurs to learn that the DNA of the all-important brewing yeast– the building blocks of the perfect stout– is the same as that which encodes the yeast required to brew a clean, crisp lager.
How was human evolution and migration influenced by past changes in climate? This question has led researchers to drill day and night to great depths in a dried up lake in east Africa. The Chew Bahir Drilling Project, in a remote part of south Ethiopia, will provide a sedimentary record of changes in rainfall, temperature and vegetation, spanning the last 500,000 years of human evolution.
Two identical cigarettes led to a discovery by scientists. Study participants inhaled nicotine, yet they showed significantly different brain activity. Why the difference? Some subjects were told their cigarettes were nicotine free.
Attempts to quarantine health workers returning from Ebola-stricken West Africa were a mistake, the president's bioethics advisers said today. The panel concluded that the nation must improve its health infrastructure and emergency response to be ready to respond quickly to next major disease outbreak.
Inflammation— the body’s response to damaging stimuli— may have a protective effect against cardiovascular disease, according to a study. The finding is one of the outcomes of research using a powerful new genetic tool— containing data from over a million individuals— that mimics the behavior of certain anti-inflammatory drugs.
A team has discovered that 22 species of mammals– from humans, to hedgehogs to giraffes– are the same: their eyelash length is one-third the width of their eye. Anything shorter or longer, including the fake eyelashes that are popular in Hollywood and make-up aisles, increases airflow around the eye and leads to more dust hitting the surface.
A spacewalking astronaut ended up with unwanted water in his helmet after breezing through a cable and lube job outside the International Space Station. The leak was scarily reminiscent of a near-drowning outside the orbiting complex nearly two years ago.
Computers already have bested human champions in "Jeopardy!" and chess, but artificial intelligence now has gone to master an entirely new level: "Space Invaders." Google scientists have cooked up software that can do better than humans on dozens of Atari video games from the 1980s but not "Ms. Pac Man."
John Harvey Kellogg, born Feb. 26, 1852, was an American medical doctor who ran a sanitarium using holistic methods, with a particular focus on nutrition, enemas and exercise. Kellogg was an advocate of vegetarianism who advised low calorie diets and developed peanut butter, corn flakes and granola.
A survey of rice, wheat, barley, fruit and vegetable crops found that most mutants created by advanced genetic engineering techniques may be out of the scope of current genetically modified organism (GMO) regulations. Now, two bioethicists are proposing new regulatory models for genome-edited crops and call for clarifying the social issues associated with such genetically engineered crops.
A protein that protects ticks from freezing temperatures also prevents frostbite when introduced in mice, a study has found. The research is the first to demonstrate the protein's ability to boost frostbite resistance in an adult mammal.
People who sleep for more than eight hours a day have an increased risk of stroke, according to a study. This risk doubles for older people who persistently sleep longer than average. However, the researchers say it is unclear why this association exists and call for further research to explore the link.
The key to geysers is an underground bend or loop that traps steam and then bubbles it out slowly to heat the water column above until it is just short of boiling. Eventually, the steam bubbles trigger sudden boiling from the top of the column, releasing pressure on the water below and allowing it to boil as well.
Many car buyers weighing whether they should go all electric to help the planet have at least one new factor to consider before making the switch: geography. Based on a study of a commercially available electric car, scientists are reporting that emissions and driving range can vary greatly depending on regional energy sources and climate.
