| New biomarker predicts development of preeclampsia at six weeks of pregnancy Posted: 20 Nov 2015 07:41 AM PST Preeclampsia is generally diagnosed later in pregnancy, but new research reports that the protein copeptin can predict the development of preeclampsia as early as six weeks of gestation. The findings could lead to diagnosis of the disorder in the first trimester, improving care and potentially leading to the development of preventative measures. |

| Surprising signal to control male fertility Posted: 20 Nov 2015 07:37 AM PST Sperm cells mature during their transit in the epididymis and thus acquire their ability to fertilize ova. Scientists have now discovered that signaling molecules of the Wnt family coordinate this maturation process. A surprising finding is that Wnt signaling, which is extremely important in embryonic development, acts upon spermatozoa in a way that differs from the known one. |
| Ground-breaking research could challenge underlying principles of physics Posted: 20 Nov 2015 06:44 AM PST An international team of physicists has published ground-breaking research on the decay of subatomic particles called kaons - which could change how scientists understand the formation of the universe. Scientists devised the first calculation of how the behavior of kaons differs when matter is swapped out for antimatter, known as direct "CP" symmetry violation. Should the calculation not match experimental results, it would be conclusive evidence of new, unknown phenomena that lie outside of the Standard Model-physicists' present understanding of the fundamental particles and the forces between them. |
| High frequency stimulation in pain medicine Posted: 20 Nov 2015 06:44 AM PST Due to disease-related changes in their brain, pain patients often suffer from an impaired tactile ability in their hands. In a new study, high frequency repetitive stimulation was investigated as a therapeutic approach for these patients. The results of this study show that passive stimulation of this kind is a promising new therapy option. |
| 3D imaging sheds new light on 250 million year old fossil Posted: 20 Nov 2015 06:41 AM PST A new study has used high-resolution imaging techniques to reinterpret fossilized bones first encountered in northeast Italy in 1989. |
| Sea traffic pollutes our lungs more than previously thought Posted: 20 Nov 2015 06:41 AM PST New data show that the air along the coasts is full of hazardous nanoparticles from sea traffic. Almost half of the measured particles stem from sea traffic emissions, while the rest is deemed to be mainly from cars but also industries and natural particles from the sea. |
| How fast you move can predict how healthy you'll be Posted: 20 Nov 2015 06:41 AM PST Instead of focusing on drawing out the length of life, researchers have created a tool that can be used for accurately predicting lifespan as well as assessing the current health state, and discovered the regulatory mechanism that extends "healthspan", the time in which an organism is at its optimal health. |
| Ghostly and beautiful: 'Planetary nebulae' get more meaningful physical presence Posted: 20 Nov 2015 06:41 AM PST A way of estimating more accurate distances to the thousands of so-called planetary nebulae dispersed across our Galaxy has been announced by a team of three astronomers. |
| Cuckoo sheds new light on the scientific mystery of bird migration Posted: 20 Nov 2015 06:21 AM PST The cuckoo is not only capable of finding its way from unknown locations; it does this through a highly complex individual decision making process. Such skills have never before been documented in migratory birds. A new study using miniature satellite tracking technology shows that navigation in migratory birds is even more complex than previously assumed. |
| The search for happiness: Using MRI to find where happiness happens Posted: 20 Nov 2015 06:21 AM PST Researchers have mapped out using MRI where happiness emerges in the brain. The study paves the way for measuring happiness objectively -- and also provides insights on a neurologically based way of being happy. |
| ADHD meds may be a prescription for bullying Posted: 20 Nov 2015 06:21 AM PST Kids and teens who take medications like Ritalin to treat attention-deficit hyperactivity disorder are twice as likely to be physically or emotionally bullied by peers than those who don't have ADHD. |
| Tattoos may be a coping mechanism for some college-age women Posted: 19 Nov 2015 06:17 PM PST Women with multiple tattoos report higher self-esteem than anyone else in a recent study, and escalating acquisition of body art does not correlate with increased depression or suicide ideation. However, the same multi-tattooed women also report a much higher frequency of past suicide attempts. |
| Moderate amounts of caffeine during pregnancy do not harm baby's IQ, study suggests Posted: 19 Nov 2015 06:14 PM PST Women drinking and eating moderate amounts of caffeine during pregnancy should be reassured that they are not harming their child's intelligence, according to a new study. |
| To feed or not to feed: Researchers engage citizen scientists in reducing bird-window collisions Posted: 19 Nov 2015 06:14 PM PST Getting in touch with nature in an urbanized world can be as simple as putting a bird feeder in your backyard. However, what are the potential consequences of this act? Bird-window collisions are one of the largest threats facing urban bird populations.

| Secrets of dark proteome Posted: 19 Nov 2015 08:35 AM PST Scientists have long speculated about the nature of the dark proteome, the area of proteins that are completely unknown, but a recent study has mapped the boundaries of these dark regions, bringing us one step closer to discovering the complete structure and function of all proteins. |
| Chemical engineers have figured out how to make vaccines faster Posted: 19 Nov 2015 08:35 AM PST A new system has been created to speed up the process of making life-saving vaccines for new viruses. Their concept is to create the biological machinery for vaccine production en masse, put it in a freeze-dried state and stockpile it around the country. Then, when a new virus hits, labs can simply add water to a 'kit' to rapidly produce vaccines. |
| Mutations in key cancer protein suggest new route to treatments Posted: 19 Nov 2015 08:35 AM PST Researchers found they could disrupt STAT3's ability to act as a transcription factor by altering part of the protein, which interfered with its cancer-promoting activity.
