A hard drive from space: Hidden magnetic messages uncovered

The dying moments of an asteroid's magnetic field have been successfully captured by researchers, in a study that offers a tantalising glimpse of what may happen to the Earth's magnetic core billions of years from now.

Magnetic fields help in formation of massive stars

Magnetic fields in massive dark clouds are strong enough to support the regions against collapse due to their own gravity. A study lead by researchers at the Max Planck Institute for Radio Astronomy in Bonn has now shown for the first time that high magnetization sets the stage for the formation of stars much more massive than the sun. This was demonstrated in observations of polarized dust emission from two of the most massive clouds in our Milky Way, the "Brick" and "Snake."

Huge asteroid to whip past Earth on Monday

An asteroid up to 1,800 feet (550 meters) across is headed Earth's way. But don't worry: It will miss us by 745,000 miles, about three times the distance between Earth and the moon.

Students to send life to Mars onboard Mars One lander in 2018

The first step to establish a permanent colony on Mars could be taken in 2018 when a group of European students will send its project to the Red Planet. The team composed of students from Portugal, Spain and Netherlands has won the Mars One University Competition which offers a one way ticket to Mars for a scientific payload. The winning project which aims to germinate the first seed on the Red Planet, will fly to the surface of Mars onboard the Mars One unmanned lander scheduled to be launched in 2018. "We wanted to perform a useful experiment in order to establish a permanent human colony on the Red Planet before 2030, where any kind of vital support is required," Miguel Valbuena of the Biological Research Centre in Madrid (Spain) and the 'Seed' project team member told astrowatch.net. "Plants could supply oxygen and food, but according to several researches on the International Space Station, plants have trouble to grow in an environment outside Earth. We would like to check in situ the real difficulties for plant development, monitoring the growth of some seeds that in the future could serve as vital support for the first humans on Mars."

Busy year of 13 launches by ULA in 2015 begins with blastoffs for the navy and NASA

A busy year of 13 space launches by rocket provider United Launch Alliance (ULA) in 2015 begins with a pair of blastoffs for the US Navy and NASA tonight and next week, emanating from both the US East and West Coasts.

Opportunity's breathtaking view from atop Cape Tribulation

Imagine if you were standing on Mars, beside the Opportunity rover, high on the summit of Cape Tribulation. You don't have to leave too much to the imagination, thanks to imaging enthusiast Stu Atkinson. He's put together a magnificent colorized version of Oppy's recent panoramic view, atop the highest elevation that the rover will ever reach, perched on the west rim of Endeavour crater.

Space Station worms' research potential is anything but flat

For years, it was assumed the world was flat. Now, we have a laboratory that orbits our big, blue marble. So, it's funny to think of returning to flatness aboard the International Space Station, but this outpost currently houses flatworms for research. The study of these creatures has the potential to be rather robust in implications for regenerative medicine, an area of treatment for repairing or replacing human cells, tissues or organs on Earth to restore normal function. A new study launched aboard SpaceX's fifth commercial resupply services (CRS) mission to the space station examines the reparative processes of flatworms in microgravity.

Stepping stones to NASA's human missions beyond

"That's one small step for (a) man; one giant leap for mankind." When Neil Armstrong took his first steps on the moon, many strides came before to achieve that moment in history. The same is true for a human mission to Mars. One step towards that journey begins in March 2015, when NASA astronaut Scott Kelly will make history as the first American to spend a year in space.

Medicine & Health news

Mutated ATRX gene linked to brain tumors potential biomarker for rare adrenal tumors too

A somatic mutation in the ATRX gene has recently been shown as a potential molecular marker for aggressive brain tumors, such as gliomas, neuroblastomas and pancreatic neuroendocrine tumors. Now, for the first time, researchers at Penn's Abramson Cancer Center have found that the same mutated gene may serve as a much-needed biomarker for the pheochromocytomas and paragangliomas (PCC/PGL) that become malignant. These rare neuroendocrine tumors are typically benign, but when they go rogue, they become very aggressive.

Study suggests some women feel more physical pain when their romantic partner is present

(Medical Xpress)—A team of researchers affiliated with several medical institutions in the U.K. has found that some women who avoid closeness in relationships tended to feel more pain during an experiment, than did women who did not avoid such closeness. In their paper published in the journal Social Cognitive and Affective Neuroscience, the team describes their experiments with female volunteers and what it might mean for women experiencing childbirth.

Researchers find where visual memories are made

In findings that may lead to new treatments for cognitive disorders, researchers at MIT's Picower Institute for Learning and Memory zero in on how the brain forms memories of what has been seen.

Friends know how long you'll live, study finds

Young lovers walking down the aisle may dream of long and healthy lives together, but close friends in the wedding party may have a better sense of whether those wishes will come true, suggests new research on personality and longevity from Washington University in St. Louis.

Seeing is not remembering

People may have to "turn on" their memories in order to remember even the simplest details of an experience, according to Penn State psychologists. This finding, which has been named "attribute amnesia," indicates that memory is far more selective than previously thought.

Blood vessels in older brains break down, possibly leading to Alzheimer's

University of Southern California (USC) neuroscientists may have unlocked another puzzle to preventing risks that can lead to Alzheimer's disease. Researchers at Keck Medicine of USC used high-resolution imaging of the living human brain to show for the first time that the brain's protective blood barrier becomes leaky with age, starting at the hippocampus, a critical learning and memory center that is damaged by Alzheimer's disease.

Researchers reveal how the mundane can be meaningful—and remembered

It's not surprising that our memories of highly emotional events, such as 9/11 or the birth of a child, are quite strong. But can these events change our memories of the past? In a study published in the journal Nature, NYU researchers report that emotional learning can lead to the strengthening of older memories.

Fatty acids in fish may shield brain from mercury damage

New findings from research in the Seychelles provide further evidence that the benefits of fish consumption on prenatal development may offset the risks associated with mercury exposure. In fact, the new study, which appears today in the American Journal of Clinical Nutrition, suggests that the nutrients found in fish have properties that protect the brain from the potential toxic effects of the chemical.

Twitter can predict rates of coronary heart disease, research says

Twitter has broken news stories, launched and ended careers, started social movements and toppled governments, all by being an easy, direct and immediate way for people to share what's on their minds. Researchers from the University of Pennsylvania have now shown that the social media platform has another use: Twitter can serve as a dashboard indicator of a community's psychological well being and can predict rates of heart disease.

Neuroscientists cracking brain's genetic code

In the largest collaborative study of the brain to date, researchers from the Keck School of Medicine of the University of Southern California (USC) led a global consortium of 190 institutions to identify eight common genetic mutations that appear to age the brain an average of three years. The discovery could lead to targeted therapies and interventions for Alzheimer's disease, autism and other neurological conditions.

Lifestyle modifications that that may reduce risk of cancer

Cancer can be seen as striking haphazardly, but research over the past 40 years shows that lifestyle factors play a huge role in cancer incidence and mortality. Dr. Graham Colditz, an internationally recognized disease-prevention expert at Siteman Cancer Center at Barnes-Jewish Hospital, has put together a list of behaviors that greatly reduce overall cancer risk. And they're not as complicated as you might think. For a healthy 2015, Colditz suggests starting with one or two from the list. Once you've got those down, move on to the others.

Bioethicists call for return to asylums for long-term psychiatric care

As the United States population has doubled since 1955, the number of inpatient psychiatric beds in the United States has been cut by nearly 95 percent to just 45,000, a wholly inadequate equation when considering that there are currently 10 million U.S. residents with serious mental illness. A new viewpoint in JAMA,written by Dominic Sisti, PhD, Andrea Segal, MS, and Ezekiel Emanuel, MD, PhD, of the department of Medical Ethics and Health Policy in the Perelman School of Medicine at the University of Pennsylvania, looks at the evolution away from inpatient psychiatric beds, evaluates the current system for housing and treating the mentally ill, and then suggests a modern approach to institutionalized mental health care as a solution.

Toward a cocaine vaccine to help addicts kick the habit

In their decades-long search for vaccines against drugs of abuse, scientists have hit upon a new approach to annul cocaine's addictive buzz. They report in the ACS journal Molecular Pharmaceutics that their strategy, which they tested on mice, harnesses a bacterial protein to trigger an immune system attack on the drug if it enters the body. This response could dull cocaine's psychotropic effects and potentially help users of the drug kick the habit.

Immune system may play key role in viral therapy's effectiveness against tumors

Viral therapy for childhood cancer could possibly improve if treatments such as chemotherapy do not first suppress patients' immune systems, according to findings published today in the journal Molecular Therapy—Oncolytics.

A call for a new model to evaluate medical schools

Over the past 100 years, licensing and accrediting bodies have raised the quality of medical education and efforts have been made to ensure that medical schools meet a minimum standard for the curricula and clinical training they offer to students. However, comparing institutions and identifying which ones produce the physicians who provide the best patient care and conduct the best biomedical research remains challenging for prospective students. A popular method for comparing medical schools, the analysis performed by U.S. News and World Report (USN&WR), has become the unofficial default tool for these types of comparisons. In a new study, researchers from Brigham and Women's Hospital (BWH) present a new model to evaluate medical schools' production of academic physicians with biomedical research careers. This model is based on relevant and accessible objective criteria that researchers propose should replace the subjective crit! eria used in the current USN&WR rankings system. These findings are published online in Academic Medicine on January 21, 2015.
