One huge advantage of drones is that these little robots can go places where people can't, including areas that might be too dangerous, such as unstable structures after a natural disaster or a region with unexploded devices.
DALLAS - Dec. 8, 2020 - Two studies led by UT Southwestern researchers shed new light on how the brain encodes time and place into memories.
Study shows that active surveillance holds promise as a treatment option for low-risk thyroid cancer
Results from a new study co-led by researchers at Dartmouth's Geisel School of Medicine and the Department of Surgery at Kuma Hospital in Kobe, Japan show that active surveillance can be successfully implemented as a viable treatment option for patients with low-risk thyroid cancer. The study is the first to specifically analyze patient retention and adherence in an active surveillance program for thyroid cancer.

1. Hydroxychloroquine shows no benefit for postexposure prophylaxis for preventing SARS-CoV-2 infection
The ability to culture cerebral organoids or "minibrains" using stem cells derived from people has given scientists experimentally manipulable models of human neurological development and disease, but not without confounding challenges. No two organoids are alike and none of them resemble actual brains. This "snowflake" problem has held back the science by making scientifically meaningful quantitative comparisons difficult to achieve.
New research from University of Warwick shows that knee replacement surgery using a tourniquet increases the risk of serious complications, and causes additional pain after surgery
A tourniquet is a device which is wrapped tightly around the thigh to stop blood flow to the rest of the leg
Researchers calculate that a change in knee replacement surgical practice might avoid nearly 2,000 serious complications a year in the UK alone
The research shows that when a tourniquet is used patients have on average nearly 20% more pain the day after the surgery
Cancer drugs have side effects, so for many years, scientists have been exploring ways to transport the active substances to a tumour in the body as precisely as possible. That is the only place that drugs should take effect. One approach is to inject them into the bloodstream and control their transport in small vessels at tumour sites by locally altering the blood flow with tiny vehicles. Research laboratories have created microrobots whose shape and propulsion are inspired by bacteria and that are small enough to be inserted into blood vessels.
Observations conducted by the Murikabushi Telescope of Ishigakijima Astronomical Observatory confirmed that dark coating can reduce satellite reflectivity by half. There are concerns that numerous artificial satellites in orbit could impair astronomical observations, but these findings may help alleviate such conditions.
An international research team has clarified the regulatory mechanism of the ubiquitin-proteasome system (*1) in recognizing and repairing DNA that has been damaged by ultraviolet (UV) light. The investigators at Kobe University (Japan), the National Institute of Health Sciences (Japan), the Catholic University of Louvain (Belgium), Kyoto University (Japan), and the National Institute of Genetics (Japan) have published their results in the journal Scientific Reports.

A research group from Tohoku University led by current president Hideo Ohno has developed the world's smallest (2.3 nm) high-performance magnetic tunnel junctions (MTJs). This work is expected to accelerate the advancement of ultrahigh-density, low-power, high-performance non-volatile memory for a variety of applications, such as IoT, AI, and automobiles.
University of Tartu researchers and their collaborators from Finland and Spain investigated the relationship between the gut microbiome and polycystic ovary syndrome. Their study revealed that women with polycystic ovary syndrome in their late reproductive years have significant microbial changes in gut-related to their metabolic health.
The members of ACNP have been motivated by recent events to strengthen diversity and inclusivity programs within the College and find ways to promote change in our home institutions. Two Annual Meeting Study Groups provided both information and practical action steps for members. The first addressed the challenge of moving beyond diversity and inclusivity as "buzzwords" toward institutional change. Evidence-based strategies were discussed that can be used widely at academic institutions, in medical and scientific education specifically, within ACNP and at members' home institutions.
A new study provides the first detailed documentation of a shallow water fish diving 450 feet deep to spawn. Uncovering this very rare spawning behavior in bonefish (Albula vulpes) is unprecedented.
Scientists at UNSW Sydney, together with collaborators from Western Sydney University and The Netherlands, were surprised to find that dihydrogen phosphate anions - vital inorganic ions for cellular activity - bind with other dihydrogen phosphate anions despite being negatively charged.
The same team also made a molecule that could 'grab' these dihydrogen phosphate anions and depending on what coloured light was shone on them, either increase or inhibit their movement in solution.
In recent decades China has built over 1,400 large industrial parks, a massive investment accounting for over 40 percent of the country's manufacturing jobs. However, some of these projects are more successful than others. Now, a study co-authored by an MIT professor suggests that some industrial parks appear to have been developed due to networks of political ties -- and those parks distinctly underperform their counterparts.
