Dopamine directly affects how much we enjoy music

PNAS Published January 21 Dopamine directly increases our enjoyment of listening, singing, or playing to music, which confer no known survival advantage. This double blind within-subject study directly manipulated healthy participants’ dopamine levels while they listened to music. The results indicate how an individual’s ability to absorb dopamine may play different, unforeseen roles in the […]

The American Academy of Pediatrics 2006 guidelines […]

Burgess Shale: Mysterious agnostids find a family

Proceedings of the Royal Society B: Biological Sciences Published January 16, 2019 (Brief from the Royal Society) Newly discovered 508-million-year-old fossils from the Burgess Shale preserving the soft tissues of mysterious, extinct arthropods called agnostids reveal appendages and internal organs for the first time in adult individuals. Based on this new information, researchers conclude that agnostids are […]

Burgess Shale: Trace fossils found on ancient soft-tissue shells

Royal Society Open Science Published January 16, 2019 (Brief from the Royal Society) For more than a century, British Columbia’s 508-million-year-old Burgess Shale deposits were thought to be mostly devoid of trace fossils – the tracks, trails and burrows produced by animals. However, in this study, researchers used a novel, modelling approach to show that some fossil […]

Immediate fossil fuel infrastructure phase-out may keep global warming below 1.5° C

Nature Communications Published January 15, 2019 11:00 ET (News release from Nature Research Press) Immediately starting to phase out fossil fuel infrastructure as it reaches the end of its expected lifetime may result in a 64 per cent chance that global mean temperature rise will remain below 1.5° C relative to pre-industrial levels. The research suggests […]

Blood stem-cell transplant to delay MS progression

JAMA: preliminary communication; original investigation; editorial Published January 15, 2019  11:00 ET (News release from JAMA) Researchers compared the effect of a stem cell transplant using a lower-dose, short course of more tolerable immune-specific chemotherapy and antibodies to suppress the immune system versus continuing disease-modifying therapy in 110 patients with relapsing–remitting multiple sclerosis. The stem cell transplant performed better than continued drug therapy for patients […]

How sports-related concussions or fractures affect adolescents’ quality of life

Journal of Neurosurgery: Pediatrics Published January 15, 2019  00:00 ET (News release from Journal of Neurosurgery Publishing Group) In a study of health-related quality of life in young athletes who had experienced a sports-related concussion or sports-related extremity fracture, researchers found that adolescents can experience decreased quality of life after injury. However, the deficits generally do not […]

Nesting latitude resets tree swallows’ migration cycle

Proceedings of the Royal Society B: Biological Sciences Published January 9, 2019 17:01 ET (Brief from the Royal Society) Tracking 133 migratory tree swallows from Alaska to North Carolina, researchers showed how the latitude at which each bird breeds has lasting, cumulative effects on timing of the bird’s migration and arrival and departure from stopover sites. However, […]

First observed evidence shows evolving white dwarfs cool more slowly than thought

Nature Published January 9, 2019 13:00 ET White dwarfs are stellar embers depleted of nuclear energy sources that cool over billions of years. For the first time, researchers have observed evolving white dwarf stars that cool more slowly than had been previously thought. Their observations and subsequent modelling support the theory that processes within a white […]

Second repeating fast radio burst detected from far reaches of universe

Nature: 2 articles here> and here> Published January 9, 2019 13:00 ET The international research team  using the Canadian Hydrogen Intensity Mapping Experiment (CHIME) radio telescope, in Penticton, B.C., reports a repeating fast radio burst, only the second to be recorded, and one of 13 newly detected bursts. At least seven of these bursts were recorded at 400 […]

Massive fungus shows little mutation over 2,500 years

Proceedings of the Royal Society B: Biological Sciences Published December 19, 2018 17:01 ET (Brief from the Royal Society) Researchers identified a single individual of the fungus Armillaria gallica that was extremely large – covering hundreds of tree root systems over approximately 75 hectares of forest – and at least 2,500 years old. Using whole-genome sequencing, […]

Critter confirms early branching on vertebrates’ fins-to-limbs family tree

Royal Society Open Science Published December 19, 2018 17:01 ET (Brief from the Royal Society) Aïstopods are a highly specialized group of eel-like legless early tetrapods, four-legged vertebrates, and diverged from the tetrapod family tree early on. This study reports a jaw believed to belong to an aïstopod that lived some 310 million years ago – […]

Alternative to “spooky action at a distance”

Proceedings of the Royal Society A: Mathematical and Physical Sciences Published December 19, 2018 17:01 ET (Brief from the Royal Society) The author proposes two ways to test a strange but consistent alternative to standard quantum physics that could refute the “spooky action at a distance” explanation of the standard theory. Causal quantum theory assumes that measurements are […]

Opioids not much better than alternatives for treating chronic non-cancer pain

JAMA Published December 18, 2018 11:00 ET (News releases from JAMA and McMaster University) This study combined the results of 96 randomized clinical trials with about 26,000 participants to compare opioids with placebo and non-opioid alternative pain medications for the treatment of chronic non-cancer pain. Opioids were associated with small improvements in pain and physical functioning but […]

Invasive tick could spread to Canada

Journal of Medical Entomology Published December 13, 2018  (News release from the Entomological Society of America) The Asian longhorned tick, first reported in New Jersey in early 2018, could easily spread into across much of eastern North America and the west coast.
