Sequencing the genomes of monarch butterflies from around the world, a team of scientists has made surprising new insights into the monarch's genetics. They identified a single gene that appears central to migration -- a behavior generally regarded as complex -- and another that controls pigmentation. The researchers also shed light on the evolutionary origins of the monarch.
PET/CT imaging of patients younger than 40 who were initially diagnosed with stage I–III breast cancer resulted in change of diagnosis, a study shows. While guidelines recommend FDG-PET/CT imaging only for women with stage III breast cancer, it can also help physicians more accurately diagnose young breast cancer patients initially diagnosed with earlier stages of the disease.
A new species of ant has been discovered that uses social parasitism to access host ant species' food sources and foraging trails: Cephalotes specularis, commonly known as the mirror turtle ant. Mirror turtle ants are the first-known ant species to use visual mimicry to parasitize another ant species. Show More Summary

A research team has managed to decode the process of adipogenesis by identifying the precise proteins that play the leading roles in fat absorption. There are many actors involved in the process of adipogenesis, used by the body to store the fat that it absorbs from food. Show More Summary
Inspired by a desire to help wounded soldiers, a team of researchers has created a paint-on, see-through, 'smart' bandage that glows to indicate a wound's tissue oxygenation concentration. Because oxygen plays a critical role in healing,...Show More Summary
A major medical discovery could lead to the development of an entirely new type of painkiller, scientists suggest. The new drug would offer new hope to sufferers of chronic pain conditions such as traumatic nerve injury, for which few effective painkillers are currently available, they say.
An international group of researchers has been able to isolate and characterize an important chemical intermediate whose existence has, so far, only been inferred from indirect experimental evidence.
Researchers are investigating realistic navigation for robots using computer modeling of the human eye and the brain of a rat.
In patients older than 50 years with moderate or severe chronic knee pain, acupuncture did not provide any benefit, a study has concluded. Acupuncture is the most popular of alternative medical systems. Although traditionally administered...Show More Summary
More than 80 percent of bowel cancers could be treated with existing drugs, an international team of scientists say at the conclusion of their study. The study found that medicines called 'JAK inhibitors' halted tumor growth in bowel cancers with a genetic mutation that is present in more than 80 per cent of bowel cancers. Show More Summary
Cyberbullying and hurtful "fat jokes" are disturbingly prevalent in the social media environment, especially on Twitter, says the lead author of a study that analyzed well over a million social media posts and comments about weight matters. Show More Summary
A new article looks at breast cancer and provides insight on what a patient may anticipate. Breast cancer is a malignant tumor that starts in the breast. A malignant tumor is a group of cancer cells that can invade other parts of the body. Show More Summary
Here’s another reason why it’s a good idea to hit the gym: it can improve memory. A new study shows that an intense workout of as little as 20 minutes can enhance episodic memory, also known as long-term memory for previous events, by about 10 percent in healthy young adults.
Pet food mislabeling: the issue is a significant one when it comes to commercial pet foods marketed for dogs and cats. New research set out to identify meat species present as well as any instances of mislabeling. Of the 52 products tested, 31 were labeled correctly, 20 were potentially mislabeled, and one contained a non-specific meat ingredient that could not be verified.
A new study sheds light on how some collegiate student-athletes deal with uncertainties ranging from excelling in both school and sports to their career prospects outside of athletics, and urges university athletic programs to adopt new efforts to support student-athletes.
Scientists combined graphene quantum dots drawn from common coal with graphene oxide, nitrogen and boron into a catalyst for fuel cells that outperforms platinum. Graphene quantum dots grab onto graphene platelets like barnacles attach themselves to the hull of a boat. Show More Summary
Australia needs to be proactive about potential disease outbreaks like Ebola and establish a national center for disease control, an expert says, while he questions Australia's preparation for public health crises.
This is reminiscent of how it started in Australia with the carbon tax. Look for a Climate Credit from the State of California on Your October Utility Bill This month your electricity bill will include a credit identified as the “California Climate Credit.” Twice a year, in April and October, your household and millions of…
Treating cancers with immunotherapy and radiotherapy at the same time could stop them from becoming resistant to treatment, scientists report. Radiotherapy is a very successful treatment for many forms of cancer, but in cancer cellsShow More Summary
