What does the next generation telescope need to detect life?

Almost 2,000 extrasolar planets have been discovered to date and this number is constantly increasing. Yet, we still know little about these alien worlds, especially their atmospheres. The atmospheres of terrestrial exoplanets could betray the presence of life on the planet, sparking NASA's interest in acquiring the spectra that appears as starlight shines through these planetary atmospheres.

'Eau de comet' is a bit of a stinker

Rotten eggs, horse pee, alcohol and bitter almonds: this is the bouquet of odours you would smell if a comet in deep space could be brought back to Earth, European scientists said on Thursday.

Earth hit by double asteroids 458 million years ago

Some 458 million years ago, Earth was whacked in a double asteroid strike, leaving craters visible in Sweden today, space scientists reported on Thursday.

Lucky star escapes black hole with minor damage

Astronomers have gotten the closest look yet at what happens when a black hole takes a bite out of a star—and the star lives to tell the tale.

OSIRIS images of Rosetta's comet show spectacular streams of dust emitted into space

Rosetta's comet 67P/Churyumov-Gerasimenko is beginning to show a clearly visible increase in activity. While in the past months most of the dust emitted from the body's surface seemed to originate from the neck region which connects the two lobes, images obtained by Rosetta's scientific imaging system OSIRIS now show jets of dust along almost the whole extent of the comet.

Close encounters: Comet siding spring seen next to mars

(Phys.org) —This composite NASA Hubble Space Telescope Image captures the positions of comet Siding Spring and Mars in a never-before-seen close passage of a comet by the Red Planet, which happened at 2:28 p.m. EDT October 19, 2014. The comet passed by Mars at approximately 87,000 miles (about one-third of the distance between Earth and the Moon). At that time, the comet and Mars were approximately 149 million miles from Earth.

NASA taps Livermore photon scientists for heat-shield research

Researchers in Lawrence Livermore National Laboratory's NIF & Photon Science Directorate are working with NASA Ames Research Center at Moffet Field, California on the development of technology to simulate re-entry effects on the heat shield for the Orion spacecraft, NASA's next crewed spaceship.

The formation and development of desert dunes on Titan

Combining climate models and observations of the surface of Titan from the Cassini probe, a team from the AIM Astrophysics Laboratory (CNRS / CEA / Paris Diderot University) , in collaboration with researchers at the Paris Earth Physics Institute (IPGP / CNRS / Paris Diderot University) and the Matter and Complex Systems Laboratory - MSC (CNRS / Paris Diderot University), have proposed a new formation and growth mechanism for the dunes on the surface of the moon. This growth mechanism, also seen in some terrestrial deserts and on the planet Mars, appears to be the dominant mechanism in the deserts of Titan, explaining not only the shape of the dunes, but also their orientation and direction of growth, together with their confinement to the tropical belt around the moon. The results of this study have been published in Geophysical Research Letters.

Assembly complete for NASA's maiden Orion spacecraft launching in December 2014

The search for habitable worlds, from sub-Neptunes to super-Earths

During a live Google Hangout, three astrophysicists—Zachory Berta-Thompson, Bruce Macintosh and Marie-Eve Naud—discussed the huge variety of planets discovered so far, how close we are to being able to see other Earth-like planets, and all that remains unknown.

Researchers highlight acousto-optic tunable filter technology for balloon-borne platforms

Narrowband or hyperspectral imaging is a valuable technique used in planetary science for characterizing surfaces and surrounding environments. For example, it can be used to spatially map molecular species of interest on the surface of a solid or icy body, or to sound to different depths in a giant planet atmosphere. However, conducting narrowband or hyperspectral imaging of solar system targets from a balloon-borne platform presents several technical challenges, including mechanical failures and power requirements. These risks can be mitigated with the use of an electronically tunable filter such as an acousto-optic tunable filter (AOTF).

Medicine & Health news

Researchers find novel way body defends against harmful bacteria

Bacterial infections can cause major problems for people undergoing treatment for cancer and other diseases. The concern is especially acute during hospitalization, when patients often have weakened immune function.

Stopping anti-CCL2 breast cancer treatment aggravates the disease

Mohamed Bentires-Alj and his team at the Friedrich Miescher Institute for Biomedical Research (FMI) together with scientists from the Novartis Institutes for BioMedical Research (NIBR) show in a study published today in Nature that a promising therapeutic approach for metastatic breast cancer elicits deleterious effects after cessation of the treatment. Stopping CCL2 inhibition paradoxically increases metastasis formation and leads to premature death thus thwarting the initially beneficial effects of the treatment. This has implications for the design of therapies targeting these processes and indicates that therapeutic approaches to inactivate the chemokine CCL2 should be administered with extreme caution.

Thyroid cancer genome analysis finds markers of aggressive tumors

A new comprehensive analysis of thyroid cancer from The Cancer Genome Atlas Research Network has identified markers of aggressive tumors, which could allow for better targeting of appropriate treatments to individual patients.

People with type 2 diabetes are physically less able to recover from stress

A rare form of a devastating disease which causes low blood sugar levels in babies and infants may now be recognised earlier thanks to a new test developed by researchers from The University of Manchester.

Two days later: Adolescents' conflicts with family spill over to school, vice versa

Family conflict and problems at school tend to occur together on the same day. A new study has found that these problems spill over in both directions for up to two days after. The study found that teens with more pronounced mental health symptoms, anxiety and depression, for example, are at risk for intensified spillover. The study followed over a hundred 13 to 17 year olds and their parents over a 14-day period.

'Breath test' shows promise for diagnosing fungal pneumonia

Many different microbes can cause pneumonia, and treatment may be delayed or off target if doctors cannot tell which bug is the culprit. A novel approach—analyzing a patient's breath for key chemical compounds made by the infecting microbe—may help detect invasive aspergillosis, a fungal infection that is a leading cause of mortality in patients with compromised immune systems, according to a proof-of-concept study now online in Clinical Infectious Diseases.

Children in high-quality early childhood education are buffered from changes in family income

While losses in family income predict increases in behavior problems for many children, attending high-quality early childhood education and care centers offers some protection against families' economic declines, according to a new study out of Norway. In Norway, publicly subsidized high-quality early childhood education and care is available to all children, from low-income to affluent, starting at age 1. The study found that children who don't take part in such programs have more early behavior problems when their families' income drops.

Teens whose parents exert more psychological control have trouble with closeness, independence

For teenagers, learning to establish a healthy degree of autonomy and closeness in relationships (rather than easily giving in to peer pressure) is an important task. A new longitudinal study has found one reason adolescents struggle with balancing autonomy and closeness in relationships: parents' psychological control. Teens whose parents exerted more psychological control over them when they were 13 had more problems establishing friendships and romantic relationships that balanced closeness and independence, both in adolescence and into early adulthood.

Gene that once aided survival in the Arctic found to have negative impact on health today

In individuals living in the Arctic, researchers have discovered a genetic variant that arose thousands of years ago and most likely provided an evolutionary advantage for processing high-fat diets or for surviving in a cold environment; however, the variant also seems to increase the risk of hypoglycemia, or low blood sugar, and infant mortality in today's northern populations. The findings, published online October 23 in Cell Press's American Journal of Human Genetics, provide an example of how an initially beneficial genetic change could be detrimental to future generations.

Traumatic stress may affect DNA, but psychotherapy may heal it

A new study published in the current issue of Psychotherapy and Psychosomatics for the first time demonstrates that traumatic stress may induce DNA breakage, but psychotherapy may heal it. Previous research reveals an association between traumatic stress and an increased risk for numerous diseases, including cancer. At the molecular level, stress may increase carcinogenesis via increased DNA damage and impaired DNA repair mechanisms. The authors assessed DNA breakage in peripheral blood mononuclear cells from individuals with post-traumatic stress disorder (PTSD) and measured the cellular capacity to repair single-strand breaks after exposure to ionizing X-radiation. They also investigated the effect of psychotherapy on both DNA breakage and DNA repair.

Changing lifestyle may improve cognitive function in the elderly

A randomized controlled trial published in the current issue of Psychotherapy and Psychosomatics indicates that modifications in lifestyle may improve cognitive function in the elderly. Since a healthy lifestyle may protect against cognitive decline, the authors examined outcomes in elderly individuals after 18 months of a five-group intervention program consisting of various modalities: physical activity, antismoking, social activity, cognitive activity, alcohol drinking in moderation, and leaning about body mass and a healthy diet.

New drug naming system unveiled at ECNP in Berlin

What's in a name? Doctors have found that the name of the drug you are prescribed significantly influences how the patient sees the treatment. Now in a significant shift, the world's major psychiatry organisations are proposing to completely change the terminology of the drugs used in mental disorders shifting it from symptom based (e.g. antidepressant, antipsychotic etc.) to pharmacologically based (e.g. focusing on pharmacological target (serotonin, dopamine etc.) and the relevant mode of action). This will mean that patient will no longer have the confusion of being prescribed a drug for what appears to be an unrelated condition, but also means that drug names will be more understandable to doctors.

England's NHS appeals for more government funds

Leaders of England's state-funded National Health Service (NHS) warned on Thursday that billions of pounds in extra funds were needed to maintain patient care, laying down the gauntlet to politicians ahead of May's general election.

Paperwork consumes one-sixth of US physicians' time and erodes morale, study finds

The average U.S. doctor spends 16.6 percent of his or her working hours on non-patient-related paperwork, time that might otherwise be spent caring for patients. And the more time doctors spend on such bureaucratic tasks, the unhappier they are about having chosen medicine as a career.

New, faster therapeutic hypothermia techniques

Rapid lowering of body temperature following an acute myocardial infarction (MI) can be an effective therapeutic strategy to minimize damage to the heart muscle caused by the loss and restoration of blood flow to the heart. While hypothermia shows clinical promise, current methods to cool the heart are insufficient. Faster, more effective techniques are needed to realize the full cardioprotective potential of this emerging intervention, as described in an article in Therapeutic Hypothermia and Temperature Management.

An over-the-scope clipping device for endoscopic management of gastrointestinal defects is safe and effective

An international multicenter study reports that over-the-scope clip (OTSC) placement is a safe and effective therapy for the closure of gastrointestinal (GI) defects, which includes anastomotic leaks, fistulae and perforations. Clinical success was best achieved in patients undergoing closure of perforations or leaks when OTSC placement was used for primary or rescue therapy. The overall clinical success for the closure of perforations and leaks ranged between 90 percent and 73 percent; however, successful closure of fistulae was achieved in less than half of the patients. The type of defect (i.e. perforation or leak) is the best predictor of successful long-term closure. The study appears in the October issue of GIE: Gastrointestinal Endoscopy, the monthly peer-reviewed scientific journal of the American Society for Gastrointestinal Endoscopy (ASGE).
