Study casts doubt on ketamine nasal sprays for depression

Jue, 03/15/2018 - 22:00
Researchers from UNSW Sydney and the Black Dog Institute have questioned the efficacy and safety of intranasal ketamine for depression, with their pilot trial stopped early due to poor side effects in patients.

Coral reefs suffering in Philippines despite outlawing damaging fishing practices

Jue, 03/15/2018 - 22:00
Some of the fishing methods used in today's small-scale fisheries are causing more damage to coral reefs than ever, a new UBC study has found.

Your gender may affect how you perceive a woman's anxiety in STEM

Jue, 03/15/2018 - 22:00
Undergraduate students' reactions to reading about a woman's anxiety in a science, technology, engineering and mathematics (STEM) class vary by gender according to a Dartmouth-led study published in the Psychology of Women Quarterly. Men are more likely than women to attribute a female student's anxiety or self-doubt in a STEM class to internal factors such as not being prepared while women are more likely than men to attribute such emotions to external factors, such as bias.

Reefs help protect vulnerable Caribbean fish from climate change

Jue, 03/15/2018 - 22:00
New research from UBC's Institute for the Oceans and Fisheries suggests that larger reef areas may help protect the Caribbean's coral reef fish communities from the impacts of ocean warming.

Americans slow down the clock of age

Jue, 03/15/2018 - 22:00
A close examination of national health data indicate that the rate of biological aging appears to be more delayed for all Americans, but particularly for men, which may extend their lives. Researchers cite advancements in medicine as one possible reason for the deceleration. The study appeared in Demography.

With new 'shuffling' trick, researchers can measure gene activity in single cells

Jue, 03/15/2018 - 22:00
Researchers at the University of Washington and the Allen Institute for Brain Science have developed a new method to classify and track the multitude of cells in a tissue sample. In a paper published March 15 in the journal Science, the team reports that this new approach -- known as SPLiT-seq -- reliably tracks gene activity in a tissue down to the level of single cells.

Assaults spiked on Trump rally days during 2016 election

Jue, 03/15/2018 - 22:00
Cities experienced 2.3 more assaults than average on days when hosting presidential campaign rallies for Donald Trump during the lead-up to the 2016 United States Presidential Election, according to a first of its kind study published today in Epidemiology by researchers in the Perelman School of Medicine at the University of Pennsylvania. Hillary Clinton rallies were not linked to any increase in assaults.

Sexual harassment statistics: Do the numbers reveal the true extent of the problem?

Jue, 03/15/2018 - 22:00
A new article addresses the statistics of sexual harassment and questions how prevalent it is.

Elusive venomous mammal joins the genome club

Jue, 03/15/2018 - 22:00
An article published in GigaScience presents a draft genome of a small shrew-like animal, the venomous Hispaniolan solenodon. This unusual animal is one of the only extant venomous mammals, and it is the sole remaining branch of mammals that split from other insectivores at the time of the dinosaurs. The solenodon genome sequence revealed the answer to several evolutionary questions, such as whether the solenodon species indeed survived the meteor impact that killed the dinosaurs.

Smart software can diagnose prostate cancer as well as a pathologist

Jue, 03/15/2018 - 22:00
Chinese scientists and clinicians have developed a learning artificial intelligence system which can diagnose and identify cancerous prostate samples as accurately as any pathologist. This holds out the possibility of streamlining and eliminating variation in the process of cancer diagnosis. It may also help overcome any local shortage of trained pathologists. In the longer term it may lead to automated or partially automated prostate cancer diagnosis.

Experience trumps youth among jumping fish

Jue, 03/15/2018 - 22:00
Tiny jumping fish can leap further as they get older, new research shows.

Monocrystalline silicon thin film for cost-cutting solar cells with 10-times faster growth rate fabricated

Jue, 03/15/2018 - 22:00
A research team from Tokyo Institute of Technology (Tokyo Tech) and Waseda University have successfully produced high-quality thin film monocrystalline silicon with a reduced crystal defect density down to the silicon wafer level at a growth rate that is more than 10 times higher than before. In principle, this method can improve the raw material yield to nearly 100%.
