Meteorite may represent 'bulk background' of Mars' battered crust

NWA 7034, a meteorite found a few years ago in the Moroccan desert, is like no other rock ever found on Earth. It's been shown to be a 4.4 billion-year-old chunk of the Martian crust, and according to a new analysis, rocks just like it may cover vast swaths of Mars.

Planck: Gravitational waves remain elusive

Despite earlier reports of a possible detection, a joint analysis of data from ESA's Planck satellite and the ground-based BICEP2 and Keck Array experiments has found no conclusive evidence of primordial gravitational waves.

Japan to launch new spy satellite

Japan's government said it will launch a back-up spy satellite on Sunday, after cancelling an earlier lift-off due to bad weather.

What's happening in the universe right now?

There are some topics that get a little frustrating in their pedantry, but can really draw attention to the grand scope and mechanics in our Universe. This is definitely one of them.

How are planets formed?

How did the Solar System's planets come to be? The leading theory is something known as the "protoplanet hypothesis", which essentially says that very small objects stuck to each other and grew bigger and bigger—big enough to even form the gas giants, such as Jupiter.

NASA delays soil study satellite launch for 'repairs'

NASA has pushed back the launch of a satellite to study soil moisture to Saturday, so that it can perform "minor repairs" to the launch rocket.

Video: What it would look like if the sun was replaced with other stars?

How would our horizon look if Earth orbited around another star, such as Alfa-Centauri, Sirius, or Polaris? Roscosmos TV has released two new videos that replace our familiar Sun and Moon with other stars and planets.

Going a long way to do a quick data collection

Like many a scientist before me, I have spent this week trying to grow a crystal. I wasn't fussy, it didn't have to be a single crystal – a smush of something would have done – just as long as it had a bit of long-range order. But no. Hours spent staring at a screen as the sample I wanted to study failed to sort out its atoms into something I could work with.

Medicine & Health news

New molecular target identified for treating cerebral malaria

A drug already approved for treating other diseases may be useful as a treatment for cerebral malaria, according to researchers at Harvard T. H. Chan School of Public Health. They discovered a novel link between food intake during the early stages of infection and the outcome of the disease, identifying two molecular pathways that could serve as new targets for treatment.

Sex differences found in brain mechanisms important for learning

(Medical Xpress)—Women tend to become addicted to drugs and relapse faster than men, though the biological reasons are not completely clear. Now, investigators at the Nathan Kline Institute for Psychiatric Research and Weill Cornell Medical College have discovered that high levels of estrogen may lead to a unique kind of learning that could explain why women are more susceptible to addiction.

Scientists find Ebola virus is mutating

(Medical Xpress)—Researchers working at Institut Pasteur in France have found that the Ebola virus is mutating "a lot" causing concern in the African countries where the virus has killed over eight thousand people in just several months time. In speaking with the press, they report that multiple mutations of the virus have been observed, though it is still not clear what advantage it has given the virus, if any. They also reported that they have seen many cases of people infected with the virus that did not exhibit any symptoms, which might suggest that at least one of the mutations in the virus has led to infections that are less traumatic to their victim, but which are also likely more easily spread.

Research uncovers connection between Craigslist personals, HIV trends

Craigslist's entry into a market results in a 15.9 percent increase in reported HIV cases, according to research from the University of Minnesota published in the December issue of MIS Quarterly. When mapped at the national level, more than 6,000 HIV cases annually and treatment costs estimated between $62 million and $65.3 million can be linked to the popular website.

Latent HIV may lurk in 'quiet' immune cells, research suggests

Drugs for HIV have become adept at suppressing infection, but they still can't eliminate it. That's because the medication in these pills doesn't touch the virus' hidden reserves, which lie dormant within infected white blood cells. Unlock the secrets of this pool of latent virus, scientists believe, and it may become possible to cure - not just control - HIV.

Biomaterial coating raises prospect of more successful medical implants

A novel, bacteria-repelling coating material that could increase the success of medical implants has been created by researchers.

Facebook shapes women's body image – just not as you'd expect

If you're one of the world's 1.3 billion regular Facebook users, you'll know the feeling of being consumed by your news feed.

How poverty may affect memory

Working memory, how we actively hold and manipulate information in our mind, is a cognitive skill used on a daily basis.  How effectively working memory performs, however, is not as universal as one may think.  In an open access article published in the Journal of Cognition and Development titled "Working Memory Differences Between Children Living in Rural and Urban Poverty", author Michele Tine investigated whether working memory of children living in rural poverty is distinct from the working memory profiles of children in urban poverty.  Both verbal and visuospatial tests were given to discern how memory deficits compared.

The future of precision immunology

In his State of the Union address, President Obama announced a new precision medicine initiative to work on finding a cure for cancer and other diseases. Howard L. Kaufman, a leading immunotherapy expert from Rutgers Cancer Institute of New Jersey recently shared his thoughts in the Journal of Clinical Oncology on the progress doctors have made in precision immunology – a type of precision medicine that involves creating a profile of a patient's immune system to fight disease. Kaufman, associate director for clinical science and chief surgical officer at the Cancer Institute, answered some questions from Rutgers Today on the future of the precision medicine field.

Why aren't there any human doctors in Star Wars?

Though set "a long time ago in a galaxy far, far away," it isn't hard to see in the Star Wars films a vision of our own not so distant future. But Anthony Jones, a physician with a long background in health care technology development, sees the Star Wars vision of medicine's future as sheer fantasy. Specifically, he is struck by the dearth of doctors – at least human ones. "In Star Wars," he says, "there are no people practicing medicine. Caring for patients seems to have been taken over by machines."

Sequencing genetic duplications could aid clinical interpretation

Copy number variations (deletions or duplications of large chunks of the genome) are a major cause of birth defects, intellectual disability, autism spectrum disorder and other developmental disorders. Still, geneticists can definitively say how a CNV, once discovered in someone's DNA, leads to one of these conditions in just a fraction of cases.

Obama calls on Congress to fund 'precision medicine' studies

Further dangers of smoking while pregnant revealed by new study

Smoking while pregnant causes chemical changes to the DNA of a foetus detectable from as early as 12 weeks and may predispose children born to smokers to a range of health conditions which last throughout life, new research by Scottish academics has revealed.

Eyes, ears and nose may aid Alzheimer's disease prevention and treatment

Detecting a decline in certain sensory functions may become the future of preventing Alzheimer's disease (AD), with research showing smell testing and retinal imaging to be strong predictors of dementia risk.

Hot on the trail of the hepatitis-liver cancer connection

Using whole genomic sequencing, scientists from RIKEN in Japan have for the first time demonstrated the profound effect that chronic hepatitis infection and inflammation can have on the genetic mutations found in tumors of the liver, potentially paving the way to a better understanding of the mechanisms through which these chronic infections can lead to cancer. Primary liver cancer is the third leading cause of cancer death worldwide, and recent studies have shown that particularly in Asia, infection with either hepatitis B or C is often associated with such cancers.

Stress shared by same-sex couples can have unique health impacts

Studies of stress and its effects on health have typically focused on the worries of an individual: money, love, health, work. But what about stress shared by two people in a romantic relationship?

Research finds 90 percent of home chefs contaminate food

What exactly is coronavirus?

The conflicts in Syria and Iraq are straining public health systems and public health efforts meant to prevent and detect the spread of infectious diseases. This is generating a "perfect storm" of conditions for outbreaks. Among the infections raising concern is Middle East Respiratory Syndrome, caused by a type of coronavirus, which emerged in 2012.

Team discovers key to preventing blindness and stroke devastation

Research led by Nicolas Bazan, MD, PhD, Boyd Professor, Ernest C. and Yvette C.

Researchers reveal how pancreatic cancer cells sidestep chemotherapy

Pancreatic cancer is one of the deadliest forms of the disease. The American Cancer Society's most recent estimates for 2014 show that over 46,000 people will be diagnosed with pancreatic cancer and more than 39,000 will die from it. Now, research led by Timothy J. Yen, PhD, Professor at Fox Chase Cancer Center, reveals that one reason this deadly form of cancer can be so challenging to treat is because its cells have found a way to sidestep chemotherapy. They hijack the vitamin D receptor, normally associated with bone health, and re-purposed it to repair the damage caused by chemotherapy. The findings, which will be published in the January 3 issue of the journal Cell Cycle, raise hopes that doctors will one day find a way to turn this process against the tumor and help chemotherapy do its job.

Cardiothoracic surgeon performs unusual surgery on elite athlete

From the time he was about 8 years old, Shahab Maslehati had been well aware that his chest was sunken. It had become more pronounced in adolescence, a time when, as he put it, "you're naturally self-conscious about everything." But it hadn't affected his high-school basketball career or his life in general into his early to mid-twenties. He graduated from Colorado State University in 2006 and took a job with the Farm Credit Administration in Denver, where he's worked ever since.
