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.
Carbohydrates, commonly known as sugars, are complex biological molecules linked to many fundamental cellular processes in living organisms. But, scientists have identified problems with nearly half of the structural data on carbohydrate molecules available to the scientific community.
A team of specialists has established the exact source of a diamond-bearing rock for the first time. These rocks, orangeites, are already commonly found in South Africa. However, the new study now reveals that they may be present in much higher abundance worldwide.
The Deepwater Horizon oil rig exploded on April 20, 2010. Five years after the nation's worst offshore oil spill, the industry is working on drilling even further into the risky depths beneath the Gulf of Mexico to tap massive deposits once thought unreachable.
For years, belly fat has been linked to high blood pressure, or hypertension, which increases a person’s risk for cardiovascular disease. But scientists haven’t known exactly why. Now, researchers are suggesting that high blood pressure could be caused by belly fat hormones “talking” with blood vessels in the abdomen.
Research has revealed that the color of light has a major impact on how our body clock measures the time of day. It’s the first time the impact of color has been tested and demonstrates that color provides a more reliable way of telling the time than measuring brightness.
New analysis of world-famous 3.46-billion-year-old rocks by researchers is set to finally resolve a long-running evolutionary controversy. The new research shows that structures once thought to be Earth's oldest microfossils do not compare with younger fossil candidates but have, instead, the character of peculiarly shaped minerals.
Counterfeit medicines are a “global pandemic” that has never been bigger – and which remains largely uninvestigated, according to research published today.
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.
