NASA's Aqua satellite provided infrared and visible views of Typhoon Lekima as it was approaching landfall in China. China has posted Typhoon and Heavy Rain Warnings for Lekima.
At human scale, controlling temperature is a straightforward concept. Turtles sun themselves to keep warm. To cool a pie fresh from the oven, place it on a room-temperature countertop.
At the nanoscale -- at distances less than 1/100th the width of the thinnest human hair -- controlling temperature is much more difficult. Nanoscale distances are so small that objects easily become thermally coupled: If one object heats up to a certain temperature, so does its neighbor.
Los Angeles - UCLA researchers have developed an artificial intelligence system that could help pathologists read biopsies more accurately and to better detect and diagnose breast cancer.
The new system, described in a study published in JAMA Network Open, helps interpret medical images used to diagnose breast cancer that can be difficult for the human eye to classify, and it does so nearly as accurately or better as experienced pathologists.
BUFFALO, N.Y. -- A thin film that reflects light in intriguing ways could be used to make road signs that shine brightly and change color at night, according to a study that will be published on Aug. 9 in Science Advances.
The technology could help call attention to important traffic information when it's dark, with potential benefits for both drivers and pedestrians, researchers say.
Could large TV monitors in waiting rooms, informing visitors about current local medical research, be a good idea? A study shows that people provided with news in this way are more interested in medical research than those randomly excluded from the news flow.
"Simply expressed, interest was 30 percent higher in the group that had received the news, and there's no doubt that was statistically significant," says Ronny Gunnarsson, Adjunct Professor of General Practice at Sahlgrenska Academy, University of Gothenburg, the study's lead author.
Stem cells hold the key for tissue engineering, as they develop into specialised cell types throughout the body including in teeth. An international team of researchers, including scientists from the Biotechnology Center of the TU Dresden (BIOTEC), has found a new mechanism that could offer a potential new solution to tooth repair. They discovered a new population of mesenchymal stromal cells in a continuously growing mouse incisor model. They have shown that these cells contribute to the formation of dentin, the hard tissue that covers the main body of a tooth.
Generally speaking, most people find the idea of workers being replaced by robots or software worse than if the jobs are taken over by other workers. But when their own jobs are at stake, people would rather prefer to be replaced by robots than by another employee. That is the conclusion of a study by the Technical University of Munich (TUM) and Erasmus University in Rotterdam.
Typhoon Krosa is a large storm moving through the Northwestern Pacific Ocean and infrared imagery from NASA's Aqua satellite revealed that the large typhoon also has a large eye.
A technology that can obtain high-resolution, micrometer-sized images for mass spectrometric analysis without sample preparation has been developed. DGIST Research Fellow Jae Young Kim and Chair-professor Dae Won Moon's team succeeded in developing the precise analysis and micrometer-sized imaging of bio samples using a small and inexpensive laser.
In recent decades, patients in Europe coming in for colectomies, or surgical procedures targeted at the colon, have not been routinely subjected to what is known as bowel preparation, where the bowel is emptied before the operation. In the United States , on the other hand, cleansing the bowel is relatively common.
Most of us know this phenomenon only too well: as soon as it is hot outside, you get an appetite for a cooling ice cream. But would you have thought that mathematics could be involved?
Let us explain: The rising temperatures and the rising ice consumption are two statistical variables in linear dependence; they are correlated.
In statistics, correlations are important for predicting the future behaviour of variables. Such scientific forecasts are frequently requested by the media, be it for football or election results.
There is nothing to be gained by operating on a patient with a so-called displaced fracture of the shoulder. Three weeks with the arm in a sling so that the shoulder is kept inactive yields the same results.
This is documented by a new study with researchers from Aarhus University, Viborg Regional Hospital, Denmark, and a number of university departments in Finland, Estonia and Sweden.
The results of the study have just been published in the scientific journal PLOS Medicine.
The first example of "nest"-building in an African amphibian, the Goliath frog, has been described in a new article in the Journal of Natural History, and could explain why they have grown to be giant.
Researchers observed adult Goliath frogs in the wild and found that they move rocks weighing up to 2kg while building ponds for their young, which they then guard. Goliath frogs themselves weigh up to 3.3kg and their bodies reach over 34cm, without including their legs.
A new study from American Cancer Society investigators finds cancer survivors in high deductible health plans were more likely to report delaying or foregoing care. The study appears in the Journal of Oncology Practice. Below is a short recap of the study by lead author Zhiyuan "Jason" Zheng, PhD, principal scientist, health services research at the American Cancer Society.
Question Asked:
How do high-deductible health plan (HDHP) enrollment and health savings account (HSA) status affect cancer survivorship, access to care, and health care utilization?
Glioblastoma is an aggressive form of brain cancer that infiltrates surrounding brain tissue, making it extremely difficult to treat with surgery. Even when chemotherapy and radiation successfully destroy the bulk of a patient's glioblastoma cells, they may not affect the cancer stem cells. This small population of tumor cells have the capacity to grow and multiply indefinitely, and can lead to tumor recurrence.
