A bastard seal from the past reveals the potential for human hybrids

If discovered as fossils, grey and ringed seals are so different that they could be classified as belonging to different families. Yet, a seal pup born in 1929 was found to be an almost perfect intermediate between the species. Compared to Neanderthals and modern humans, grey and ringed seals are genetically and dentally at least twice as different, suggesting that there may be more fossil human hybrids to be discovered. from Latest Science News -- ScienceDaily https://ift.tt/2BI2zAW

Greenhouse gas 'detergent' recycles itself in atmosphere

A simple molecule in the atmosphere that acts as a 'detergent' to breakdown methane and other greenhouse gases has been found to recycle itself to maintain a steady global presence in the face of rising emissions, according to new research. Understanding its role in the atmosphere is critical for determining the lifetime of methane, a powerful contributor to climate change. from Latest Science News -- ScienceDaily https://ift.tt/2AzFKxw

Bigger brains are smarter, but not by much

Using a large dataset and controlling for a variety of factors, including sex, age, height, socioeconomic status, and genetic ancestry, scientists found that people with larger brains rated higher on measures of intelligence and educational attainment. Size was far from everything, however, explaining only about two percent of the variation in smarts. from Latest Science News -- ScienceDaily https://ift.tt/2PczP6I

Cancer drug may help treat human papillomavirus infections

Preclinical experiments suggest the cancer drugs vorinostat, belinostat and panobinostat might be repurposed to treat infections caused by human papillomaviruses, or HPVs. Highly efficacious vaccines against HPV infection exist -- including the recently approved Gardasil 9, which immunizes against nine genotypes of HPV known to cause cervical, vulvar, vaginal and anal cancers. But the vaccine needs to be given before a person becomes sexually active, since it has no therapeutic efficacy against existing HPV infections. from Latest Science News -- ScienceDaily https://ift.tt/2PdZZq1

Researchers alleviate Schizophrenia symptoms in new mouse models

Does all the tinkering in young mice hamper their brain development, causing schizophrenia-like symptoms? Or, do their brain cells develop normally, but in adulthood struggle to communicate? Researchers need to know whether to focus their efforts on brain cell development or communication, or both, because the answer to these questions implies different therapeutic approaches. from Latest Science News -- ScienceDaily https://ift.tt/2Q2yeWu

Parkinson's disease, osteoarthritis, rheumatic diseases, alcoholism and mental health disorders increase the risk of surgical complications after a hip fracture surgery, a new study analyzing nationwide registers finds. 4.6 percent of all hip surgery patients and 10 percent of total hip replacement surgery patients experienced surgical complications within three months following their surgery. from Latest Science News -- ScienceDaily https://ift.tt/2Rs5t2i

How you respond to drama depends on if you are a holistic or analytical thinker

Researchers showed volunteers the film My Sister's Keeper on a screen while the research subjects were lying down in an MRI scanner. The study compared the volunteers' brain activity, and concluded that holistic thinkers saw the film more similarly with each other than analytical thinkers. In addition, holistic thinkers processed the film's moral issues and factual connections within the film more similarly with each other than the analytical thinkers. from Latest Science News -- ScienceDaily https://ift.tt/2PbDGBh

Why patients lie to their doctors

Up to 80 percent of those surveyed have lied to their doctor about information that could impact their health, including accurately describing their diet and how often they exercise. When survey participants explained their reasoning for doing so, they said that they wanted to avoid being judged and didn't want to be lectured about how bad certain behaviors were. from Latest Science News -- ScienceDaily https://ift.tt/2DVfUaJ

A new way to see stress -- using supercomputers

Supercomputer simulations show that at the atomic level, material stress doesn't behave symmetrically. Widely-used atomic stress formulae significantly underestimate stress near stress concentrators such as dislocation core, crack tip, or interface, in a material under deformation. Supercomputers simulate force interactions of Lennard-Jones perfect single crystal of 240,000 atoms. Study findings could help scientists design new materials such as glass or metal that doesn't ice up. from Latest Science News -- ScienceDaily https://ift.tt/2RnkPVy

Focus on resistance to HIV offers insight into how to fight the virus

Of the 40 million people around the world infected with HIV, less than one per cent have immune systems strong enough to suppress the virus for extended periods of time.

Searching an artificial bee colony for real-world results

The artificial bee colony (ABC) algorithm is widely applied in many fields, but it suffers from slow convergence, so its solutions perform well in exploration but poorly in exploitation. Researchers proposed a scale-free mechanism to guide the search of the ABC algorithm. They verified that scale-free networks improve the algorithm's optimization performance and enhance the search ability of other metaheuristic algorithms. from Latest Science News -- ScienceDaily https://ift.tt/2PdiHhv

Black hole 'donuts' are actually 'fountains'

Based on computer simulations and new observations from the Atacama Large Millimeter/submillimeter Array (ALMA), researchers have found that the rings of gas surrounding active supermassive black holes are not simple donut shapes. Instead, gas expelled from the center interacts with infalling gas to create a dynamic circulation pattern, similar to a water fountain in a city park. from Latest Science News -- ScienceDaily https://ift.tt/2re8uYz

Mischievous responders taint LGBQ health estimates in national survey

Immune checkpoints could be key to treating autoimmune disease myasthenia gravis

The PD-1 immune checkpoint is essential for self-recognition by the immune system, with disruption of the pathway associated with several autoimmune disorders. However, the involvement of PD-1 and its ligand PD-L1 in muscle-weakening autoimmune disease myasthenia gravis is unclear. Now, researchers have linked increased PD-L1 expression in the muscles of myasthenia gravis patients with disease severity and shown that this could ultimately help control the immune response and modulate disease symptoms. from Latest Science News -- ScienceDaily https://ift.tt/2KJEQ6k

Triple combination cancer immunotherapy improves outcomes in preclinical melanoma model

In adoptive cell transfer immunotherapy, T cells able to recognize a tumor are harvested, expanded in the laboratory, and then reintroduced to attack the tumor.

Quirky glacial behavior explained

In August 2012, the Jakobshavn Glacier was flowing and breaking off into the sea at record speeds, three times faster than in previous years. As the glacier flowed faster, it became thinner and more unstable and in a twist, a pileup of thick ice replenished the glacier's terminus, slowing it down again.
