Researchers find second warship from WWII Battle of Midway

A crew of deep-sea explorers and historians looking for lost World War II warships have found a second Japanese aircraft carrier that went down in the historic Battle of Midway.

Neural-digital interface advances raise ethical and social issues

Human-machine interfaces raise important ethical and social issues. These technological innovations have the potential to restore, alter, or enhance cognitive or physical function in humans, but also may exacerbate existing social tensions around equality, identity, security, privacy, and access. A roundtable comprising researchers, ethicists, and an individual technology user will explore questions around the development, use, and governance of neural-digital interfaces at Neuroscience 2019, the annual meeting of the Society for Neuroscience.

Autism spectrum disorder risk linked to insufficient placental steroid

A study in experimental models suggests that allopregnanolone, one of many hormones produced by the placenta during pregnancy, is so essential to normal fetal brain development that when provision of that hormone decreases or stops abruptly—as occurs with premature birth—offspring are more likely to develop autism-like behaviors. A Children's National Hospital research team reports the findings Oct. 20, 2019, at the Neuroscience 2019 annual meeting.

Many women and health care providers assume CBD safe during pregnancy despite lack of research

While most women of childbearing age understand drinking alcohol while pregnant is harmful, they may be less skeptical about the safety of cannabidiol (CBD), even though there is no evidence to support that belief, suggests a study being presented at the Anesthesiology 2019 annual meeting.

Preliminary medical marijuana research shows promise in lessening opioid use

Medical marijuana shows early promise to lessen opioid use and potential abuse, suggests a systematic review of published studies being presented at the Anesthesiology 2019 annual meeting. However, much more rigorous scientific research must be done to determine if there truly are pain relief benefits to medical marijuana that can ease chronic pain and outweigh potential risks.

Opioids often prescribed after cesarean delivery even when not needed

Nearly 90% of women who did not use opioids in the hospital after cesarean delivery were nonetheless discharged with a prescription for opioids, according to a study presented at the Anesthesiology 2019 annual meeting. A related study showed opioid prescribing upon discharge remained high, even after improvements were made to effectively manage pain after cesarean delivery with other medications during patients' hospital stays.

Laughing gas helpful for labor pain, but epidural still top choice

Women report being very satisfied with nitrous oxide (laughing gas) to manage labor pain, experiencing no adverse side effects to the baby, although over half of the women ultimately opted for an epidural or other pain management technique, suggests a study being presented at the Anesthesiology 2019 annual meeting.

One-third of children having tonsillectomies benefitted from opioid-free surgery and recovery

Nearly one-third of children who had surgery to remove their tonsils did not need opioids to get adequate pain relief during and after surgery, according to a study presented at the Anesthesiology 2019 annual meeting.

Deep learning enlightens scholars puzzling over ancient texts

Deep learning can help scholars restore ancient Greek texts. Specifically, researchers at University of Oxford (Thea Sommerschield and Professor Jonathan Prag) and DeepMind (Yannis Assael) built Pythia, training a neural network to guess missing words or characters from Greek inscriptions.

Scanning Earth is the mission because time is running out

As a response to the climate crisis, a project effort seeks to do a LiDAR scan of the Earth's surface—as time runs out. What, that urgent? Two professors at Colorado State University appear to think so. They are archaeologist Chris Fisher and geographer, Steve Leisz.

Boeing wants it to fly, but travelers fear the 737 MAX

On September 12, Boeing started putting out 30-second videos in which employees tout its planes' safety, hoping to reassure travelers about the 737 MAX that's been grounded worldwide since two crashes that killed 346 people.

China talks up tech prowess in face of US rivalry

China on Sunday said it aims to become a "great power" in the online world and took a swipe at Washington on trade, kicking off its annual conference promoting the Communist Party's controlled and censored version of the internet.

Niger floods force 23,000 from their homes

Floods in southeast Niger have forced 23,000 people to flee their homes since early October, officials said Saturday, threatening a new humanitarian crisis in a region already wracked by Boko Haram Islamist violence.

Artificial skin creates first ticklish devices

A new interface developed by researchers in Bristol and Paris takes touch technology to the next level, by providing an artificial skin-like membrane for augmenting interactive devices such as phones, wearables or computers.

New haptic arm places robotics within easy reach

Imagine being able to build and use a robotic device without the need for expensive, specialist kit or skills. That is the vision that researchers from the University of Bristol have turned into reality, creating a lightweight, affordable and simple solution for everyday users.
