NASA missions may re-elevate Pluto and Ceres from dwarf planets to full-on planet status

Ceres is the largest object in the asteroid belt, and NASA's Dawn spacecraft will arrive at this dwarf planet on March 6, 2015.

ALMA reveals surprisingly mild environment around a supermassive black hole

A research team led by Shuro Takano at the National Astronomical Observatory of Japan (NAOJ) and Taku Nakajima at Nagoya University observed the spiral galaxy M77, also known as NGC1068, with the Atacama Large Millimeter/submillimeter Array (ALMA) and discovered that organic molecules are concentrated in a region surrounding a supermassive black hole at its center. Although these molecules around a black hole are throught to be dissociated by strong X-rays and UV photons, the research results indicate that some regions are shielded from X-rays and UV photons due to a large amount of dust and gas. These results, which were made possible by the high sensitivity and wideband observing capability of ALMA, will be a key to understanding the mysterious environment around supermassive black holes.

Water-world Earths could host life, even if they're askew

Life could be habitable on an Earth-sized waterworld tilted on its side if the oceans aren't too shallow, a new study reveals.

What is Mars made of?

For thousands of years, human beings have stared up at the sky and wondered about the Red Planet. Easily seen from Earth with the naked eye, ancient astronomers have charted its course across the heavens with regularity.

Study identifies neurons that help predict what another individual will do

Every day we make decisions based on predicting what someone else will do - from deciding whether the driver approaching an intersection will stop for the red light to determining whether a particular negotiation strategy will result in a desired outcome. Now a study by Massachusetts General Hospital (MGH) investigators has discovered two groups of neurons that play key roles in social interactions between primates - one that is activated when deciding whether to cooperate with another individual and another group involved in predicting what the other will do. Their findings appear in the March 12 issue of Cell and have been published online.

One brain area, two planning strategies

Ready to strike, the spear fisherman holds his spear above the water surface. He aims at the fish. But he is misled by the view: Due to the refraction of light on the surface, he does not see the actual location of the fish. How must his brain now plan the arm movement? Do the brain cells (neurons) reflect the position where the fish was spotted, in other words, the visual target? Or do they plan the physical target, which is the actual direction in which the arm and spear should move in order to hit the fish?

The results of their work appear online this week in Cell Reports.

Scaffold-free iPS cell-based hyaline cartilage for joint repair

Cranky knees and other joint pains are normal in the elderly and sometimes even in the young. While these pains are rarely life threatening, those who have them know the burden and effect on quality of life. In many cases, the cause is a loss of hyaline cartilage, which does not have the capacity to regenerate, meaning once gone it is gone forever. Hyaline cartilage is constituted of chondrocytes and its secretions, extracellular matrix (ECM) proteins, which includes collagens II and XI. They do not include collagen I, which is the primary collagen in fibrocartilage, or scar tissue. The key to a successful recovery then is to introduce into the deteriorated cartilage chondrocytes that secrete only hyaline cartilage ECM proteins.

Leukemia-associated mutations almost inevitable as we age

HIV latency is not an accident: It is a survival tactic employed by the virus

New research from the Gladstone Institutes for the first time provides strong evidence that HIV latency is controlled not by infected host cells, but by the virus itself. This fundamentally changes how scientists perceive latency, presenting it as an evolutionarily advantageous phenomenon rather than a biological accident.

GLP-1 secretion is reduced in overweight, pre-diabetes and type 2 diabetes

GLP-1 is a hormone that regulates glucose levels in the body by stimulating the secretion of insulin, and GLP-1 also inhibits appetite. "We have found that GLP-1 is reduced by up to 25% among people with pre-diabetes and up to 20% among obese people compared to normal weight people. This indicates that the reduction in GLP-1 is not a consequence of type 2 diabetes, but appears much earlier in the disease development and may predispose people to type 2 diabetes," says one of the lead investigators Kristine Faerch, Senior Research Fellow at the Steno Diabetes Center in Gentofte, Denmark.

Interaction of estrogen receptor and coactivators seen for first time

For more than 50 years, Dr. Bert O'Malley, chair of Baylor College of Medicine's department of molecular and cellular biology, has worked to understand the estrogen receptor, how it works and how it partners with other molecules in the cell.

Growth signal can influence cancer cells' vulnerability to drugs, study suggests

In theory, a tumor is an army of clones, made up of many copies of the original cancerous cell. But tumor cells don't always act like duplicates, and their unpredictable behavior can create problems for treatment. For while some cells within a tumor succumb to anti-cancer drugs, others may survive to bring the cancer back to life once therapy has ended.

Novel precision medicine tool could help personalize cancer treatments

By measuring how vigorously tumor cells turn on "self-destruct" signals when exposed to different cancer drugs, a novel lab test can predict within less than 24 hours which agent is most likely to work against a particular tumor, say researchers from Dana-Farber Cancer Institute.

Omega-3 fatty acids and vitamin D may control brain serotonin

Although essential marine omega-3 fatty acids and vitamin D have been shown to improve cognitive function and behavior in the context of certain brain disorders, the underlying mechanism has been unclear. In a new paper published in FASEB Journal by Rhonda Patrick, PhD and Bruce Ames, PhD of Children's Hospital Oakland Research Institute (CHORI), serotonin is explained as the possible missing link tying together why vitamin D and marine omega-3 fatty acids might ameliorate the symptoms associated with a broad array of brain disorders.

Levodopa-carbidopa intestinal gel may prove more effective for long-term treatment of PD

Although levodopa remains the "gold standard" to effectively control motor deficits in the treatment of early stage Parkinson's disease (PD), it loses effectiveness as the disease progresses. After four to six years of treatment with oral medications for Parkinson's disease, about 40% of patients experience lack of muscle control (dyskinesias), end-of-dose wearing off, and fluctuations in "On/Off" states. By nine years of treatment, about 90% will suffer these effects.
