The Justice Department and FBI have formally acknowledged that nearly every examiner in the FBI Laboratory's microscopic hair comparison unit gave flawed testimony in almost all trials in which they offered evidence against criminal defendants over more than a two-decade period before 2000.
New research proposes that chondrules, small glassy beads that make up the bulk of the most primitive meteorites, played a crucial role in the formation of planets. Simulations show how asteroid-sized planetesimals— the building blocks of planets— can grow to observed sizes by sweeping up chondrules, each only about the size of a grain of sand.
Marie and Pierre Curie isolated one-tenth of a gram of radioactive radium from several tons of pitchblende ore on April 20, 1902. In 1903, the couple shared the Nobel Prize in physics with French scientist A. Becquerel for their groundbreaking investigations of radioactivity.
New research shows the link between cancer, diabetes and cardiovascular disease. Obesity has adverse effects on the heart and can contribute to the development of cancer. But researchers tend to study these things in isolation, by disease and not by risk factor. Shared risk factors for cancer, diabetes and cardiovascular disease also include, tobacco, diet quality, physical activity and alcohol use.
In 2004, astronomers examining a map of the radiation leftover from the Big Bang discovered the Cold Spot, a larger-than-expected unusually cold area of the sky. The physics surrounding the Big Bang theory predicts warmer and cooler spots of various sizes in the infant universe, but a spot this large and this cold was unexpected. Now, a team may have found an explanation for its existence.
The editors of Laboratory Equipment want you to start your week with a smile on your face. With years of science experience, we've heard every science joke there is. So, here’s a science joke you might like. Q: Why did Mr. Ohm marry Mrs. Ohm?
The study raises tantalizing questions about the microbial diversity of our ancestors, and whether today's Western diets and lifestyles strip us of some bugs we might want back.
Broccoli sprout extract protects against oral cancer in mice and proved tolerable in a small group of healthy human volunteers. The promising results will be further explored in a human clinical trial, which will recruit participants at high risk for head and neck cancer recurrence later this year.
Next cold and flu season, a mushroom a day could help keep the doctor away, a nutritional study found last week.
A group of Mexican engineers have created technology to recover and purify, either seawater or wastewater from households, hotels, hospitals, commercial and industrial facilities, regardless of the content of pollutants and microorganisms in, incredibly, just 2.5 minutes.
A tissue-thin, food-grade film acts like a raincoat for sweet cherries, cutting rain-related cracking of the fruit in half and potentially saving a whole season’s crop. The coating is a mix of natural chemicals similar to those found in the outer skins of cherries and blueberries.
Research showing the adverse effects of sedentary office work has given standing desks and treadmill desks new attention. If you happen to be interested in using a treadmill desk, your greatest challenge may be convincing your boss. A new study shows people on treadmill desks perform cognitive tasks nearly as well as those at sitting desks, despite the fact that they’re walking.
Researchers are developing a new wearable device that turns the user’s thumbnail into a miniature wireless track pad. They envision that the technology could let users control wireless devices when their hands are full— answering the phone while cooking, for instance.
Scientists have discovered a previously unknown mechanism behind how the fat mass and obesity associated gene promotes corpulence. Their find may have important implications for future therapeutic strategies to combat weight problems.
Large cable bundles laden with dozens of channels and big price tags have pushed more people into cheaper streaming services like Netflix, Amazon and Hulu. Verizon is giving its customers more control over the channels they pay for as the cacophony of cord cutting reshapes cable TV.
