Interplanetary dust particles could deliver water and organics to jump-start life on Earth Posted: 24 Jan 2014 01:12 PM PST Researchers have discovered that interplanetary dust particles could deliver water and organics to the Earth and other terrestrial planets. "It is a thrilling possibility that this influx of dust has acted as a continuous rainfall of little reaction vessels containing both the water and organics needed for the eventual origin of life on Earth and possibly Mars," said Hope Ishii, study co-author.

Do doctors spend too much time looking at computer screen? Posted: 24 Jan 2014 08:57 AM PST When physicians spend too much time looking at the computer screen in the exam room, nonverbal cues may get overlooked and affect doctors' ability to pay attention and communicate with patients, according to a study.

One good tern deserves another: Low-power, remote monitoring of island birds cuts bills Posted: 24 Jan 2014 08:11 AM PST A new report reveals details of an energy-efficient system for monitoring wild birds that reduces power consumption without significantly compromising image quality.

When hospitals share patient records, emergency patients benefit, study suggests Posted: 24 Jan 2014 07:19 AM PST As hospitals and doctors' offices across the country race to join online systems that let them share medical information securely, a new study suggests that these systems may already be helping cut unnecessary care. Fewer emergency patients got repeated medical scans when they went to a hospital that takes part in a health information exchange,according to new findings.

Mars could have supported life: Ten years on Mars leads to livable mud Posted: 24 Jan 2014 06:37 AM PST Some of the oldest minerals ever analyzed by NASA's Mars Opportunity Rover show that around four billion years ago Mars had liquid water so fresh it could have supported life.

Material developed could speed up underwater communications by orders of magnitude Posted: 24 Jan 2014 06:37 AM PST Electrical engineering professors have taken the first steps in a project to develop fast-blinking LED systems for underwater optical communications. Scientists have shown that an artificial metamaterial can increase the light intensity and "blink speed" of a fluorescent light-emitting dye molecule.

40 percent of parents learn how to use technology from their children Posted: 24 Jan 2014 05:27 AM PST Scientists have found that youth influence their parents in all technologies studied (computer, mobile Internet, social networking) up to 40 percent of the time. The children's scores were higher compared to parents, showing that parents don't necessarily recognize the influence.

Mining no shortcut for economic independence for Greenland, report suggests Posted: 24 Jan 2014 05:26 AM PST Contrary to the hopes of many Greenlandic lawmakers, mineral and oil extraction is no shortcut for the country to obtain economic independence from the Kingdom of Denmark, a new report suggests.

New computer model may aid personalized cancer care Posted: 24 Jan 2014 05:23 AM PST Scientists have developed a mathematical model to predict how a patient's tumor is likely to behave and which of several possible treatments is most likely to be effective.

3-D Graphene: Super-capacitors from sugar bubbles Posted: 24 Jan 2014 05:23 AM PST Graphene sheets are immensely strong, lightweight and excellent at conducting electricity. Theoretically, macroscopical three-dimensional graphene assemblies should retain the properties of nanoscale graphene flakes. However, recent attempts to make 3-D graphene have resulted in weak conductivity due to poor contact between graphene sheets. Loss of strength is also a problem, and self-supporting 3-D graphene has not yet been produced.

Doctors implant first new valve device in heart patient after FDA approval Posted: 23 Jan 2014 12:47 PM PST American doctors yesterday became the first to use a new minimally invasive medical device since it received FDA approval last week. The device treats patients with severely damaged aortic heart valves who are too ill or frail to have their aortic valves replaced through traditional open-heart surgery.

Moderate doses of radiation therapy to unaffected breast may prevent second breast cancers Posted: 23 Jan 2014 11:20 AM PST Survivors of breast cancer have a one in six chance of developing breast cancer in the other breast. But a study conducted in mice suggests that survivors can dramatically reduce that risk through treatment with moderate doses of radiation to the unaffected breast at the same time that they receive radiation therapy to their affected breast. The treatment, if it works as well in humans as in mice, could prevent tens of thousands of second breast cancers.

Donors should have access to their own raw data provided to biobanks Posted: 23 Jan 2014 11:20 AM PST Scientists have called for data held in biobanks to be made accessible to the people donating material and data to them.

A new wrinkle in the control of waves: Flexible materials could provide new ways to control sound and light Posted: 23 Jan 2014 09:59 AM PST Flexible, layered materials textured with nanoscale wrinkles could provide a new way of controlling the wavelengths and distribution of waves, whether of sound or light. The new method could eventually find applications from nondestructive testing of materials to sound suppression, and could also provide new insights into soft biological systems and possibly lead to new diagnostic tools.

Genomic tumor testing conducted Posted: 22 Jan 2014 12:36 PM PST Clinical laboratory experts and physicians achieved 100 percent accuracy using new gene sequencing equipment and panels to test for abnormal DNA in cancerous tumor cells, paving the way for routine genetic testing in personalizing cancer care

X-ray diffraction technique 'maps' strain, crack propagation in metallic tubing Posted: 22 Jan 2014 10:43 AM PST A team of researchers exploring the intergranular stress corrosion cracking of a type of metallic tubing used within nuclear power plants has developed a technique to both map and predict its propagation.
