NASA’s Curiosity Mars rover is expected to remain stationary for several days of engineering analysis following an onboard fault-protection action on Feb. 27 that halted a process of transferring sample material between devices on the rover’s robotic arm.
NASA scientists studying the origin of life have reproduced uracil, cytosine, and thymine, three key components of our hereditary material, in the laboratory. They discovered that an ice sample containing pyrimidine exposed to ultraviolet radiation under space-like conditions produces these … Continue reading
Limp or firm, your handshake conveys subliminal social cues. Now, research reveals it also transmits chemical signals that could explain why the greeting evolved in the first place.
Rather than just waiting patiently for any pollinator that comes their way to start the next generation of seeds, some plants appear to recognize the best suitors and ‘turn on’ to increase the chance of success. These findings stem from … Continue reading
Researchers have taken a step closer to producing solar fuel using artificial photosynthesis. In a new study, they have successfully tracked the electrons’ rapid transit through a light-converting molecule.
Research finds that strong, reliable anti-retaliation policies can encourage employees to notify internal authorities of possible wrongdoing, but that offering monetary incentives does not necessarily influence whistleblowing behavior – or at least not right away.
Patients suffering from chronic plantar fasciitis now have a new weapon against this debilitating foot ailment. Researchers utilized ultrasound imaging and energy to penetrate, emulsify and remove diseased fasciitis tissue.
A study of how climate change has affected emperor penguins over the last 30,000 years found that only three populations may have survived during the last ice age, and that the Ross Sea in Antarctica was likely the refuge for … Continue reading
Social media has opened up a new digital world for psychology research. Researchers are developing new methods of language analysis, and how social media can be leveraged to study personality, mental and physical health, and cross-cultural differences.
Researchers have delved into the effects of experiential purchases, potential negative impacts on abundance, the psychology of lending to friends, and how the wealthy think differently about well-being.
Findings of a new reveal striking variations between countries and regions in the use of this lifesaving stem cell transplantation, and high unmet need due to a chronic shortage of resources and donors that is putting lives at risk, experts … Continue reading
Suicide rates for adults 40-64 years of age in the US have risen about 40 percent since 1999, with a sharp rise since 2007. One possible explanation could be the detrimental effects of the economic downturn of 2007-2009, leading to … Continue reading
A substantial number of prison inmates have not received treatment for mental health conditions, a expert claims. The study recommends that prisons prioritize the use of validated screening procedures for mental health disorders plus treatment.
The organisms commonly known as blue-green algae have proliferated much more rapidly than other algae in lakes across North America and Europe over the past two centuries — and in many cases the rate of increase has sharply accelerated since … Continue reading
Scientists report progress in photovoltaic research: they have improved a component that will enable solar cells to use more energy of the sun and thus create a higher current.
