The spillover effect
2021-02-01
You can't have your cake and eat it too, as the saying goes. But what if you could save your slice while enjoying the benefits at the same time? New research suggests this is possible when it comes to marine reserves.
Marine protected areas (MPAs) are among the best conservation tools at our disposal today. However, by their very nature, these reserves take away fishing grounds, which can make them unattractive to commercial fishermen. Scientists and resource managers often promote MPAs as beneficial for the fishery. In theory, they provide a refuge for stocks to rebuild and spill over into nearby waters, leading ...
Family's our focus during pandemic, study finds
2021-02-01
More fully appreciating family and engaging in more conflict are among the heightened experiences during the coronavirus pandemic, according to a new UC Riverside study.
The study from David Funder's psychology lab looked at how people experience everyday life and its situations and how those experiences change because of an extraordinary event - the global pandemic.
Undergraduate students took part in the study, which first collected responses from 544 of them in 2017, and then from 123 students during the pandemic in spring 2020, when most of the participants were sheltering at home.
The before-and-during comparison isn't all roses for pandemic living. Some everyday experiences suffer, such as conversation, finding ...

Why do psychiatric drugs help some, but not others? Study offers clues
2021-02-01
When it comes to developing drugs for mental illnesses, three confounding challenges exist:
Men and women experience them differently, with things like depression and anxiety far more common in females.
A drug that works for one person may not work for another, and side effects abound.
New CU Boulder research, published in the journal eLIfe, sheds light on one reason those individual differences may exist. Turns out a key protein in the brain called AKT may function differently in males than females.
The study also offers a closer look at where, precisely, in the brain things may go ...
Unmatched dust storms raged over Western Europe during Ice age maximum
2021-02-01
Every late winter and early spring, huge dust storms swirled across the bare and frozen landscapes of Europe during the coldest periods of the latest ice age. These paleo-tempests, which are seldom matched in our modern climate frequently covered Western Europe in some of the thickest layers of ice-age dust found anywhere previously on Earth. This is demonstrated by a series of new estimates of the sedimentation and accumulation rates of European loess layers obtained by Senior Research Scientist Denis-Didier Rousseau from Ecole Normale Supérieure in Paris, France, and colleagues. The work, which is published in Quaternary Science Reviews is part of the TiPES project on tipping points in the Earth system, coordinated by The University ...
Research catches up to world's fastest-growing plant
2021-02-01
LA JOLLA--(February 1, 2021) Wolffia, also known as duckweed, is the fastest-growing plant known, but the genetics underlying this strange little plant's success have long been a mystery to scientists. Now, thanks to advances in genome sequencing, researchers are learning what makes this plant unique--and, in the process, discovering some fundamental principles of plant biology and growth.
A multi-investigator effort led by scientists from the Salk Institute is reporting new findings about the plant's genome that explain how it's able to grow so fast. The research, published in the February 2021 issue of Genome Research, will help scientists to understand how plants make trade-offs between ...
Diabetes during pregnancy may increase risk of heart disease
2021-02-01
DALLAS, Feb. 1, 2021 -- Women with a history of diabetes during pregnancy (gestational diabetes) are twice as likely by mid-life to develop calcium in heart arteries - a strong predictor of heart disease - even if healthy blood sugar levels were attained many years after pregnancy, according to new research published today in the American Heart Association's flagship journal Circulation.
Gestational diabetes, which is high blood sugar levels (glucose intolerance) first recognized during pregnancy, affects approximately 9% of U.S. pregnancies and up to 20% worldwide. After pregnancy, women who had gestational diabetes are at higher risk of developing prediabetes or Type 2 diabetes, conditions that are risk factors ...
Nutrition, companionship reduce pain in mice with sickle cell disease, UCI-led study finds
2021-02-01
Irvine, Calif. -- Researchers from the University of California, Irvine and the University of Minnesota have found that an enriched diet and companionship can reduce pain in mice with sickle cell disease by increasing serotonin. They also discovered that duloxetine, an antidepressant that boosts serotonin levels, could be an alternative to opioids in treating chronic pain.
"Finding safe and effective alternatives to opioids is a research priority, especially for patients with sickle cell disease," said Dr. Keith Hoots, director of the Division of Blood Diseases and Resources at the National Heart, Lung, and Blood Institute. "It's encouraging to see a dose-response relationship to nutrients and companions in mice, ...
Mayo Clinic research yields breakthrough in mobile determination of QT prolongation
2021-02-01
ROCHESTER, Minn. -- Researchers from Mayo Clinic and AliveCor Inc. have been using artificial intelligence (AI) to develop a mobile device that can identify certain patients at risk of sudden cardiac death. This research has yielded a breakthrough in determining the health of the electrical recharging system in a patient's heart. The researchers determined that a smartphone-enabled mobile EKG device can rapidly and accurately determine a patient's QTc, thereby identifying patients at risk of sudden cardiac death from congenital long QT syndrome (LQTS) or drug-induced QT prolongation.
The heart beats by a complex system of electrical signals triggering regular and necessary contractions. Clinicians evaluate the heart's rate-corrected QT interval, or QTc, as a vital ...
Alternate type of surgery may prevent total knee replacement
2021-02-01
An underused type of knee surgery in younger patients, called high tibial osteotomy, shows considerable success in reducing the need for total knee replacement, according to new research in CMAJ (Canadian Medical Association Journal).
"High tibial osteotomy is a knee surgery aimed at younger patients in the earlier stages of knee osteoarthritis. One of its goals is to prevent or delay the need for knee replacement," says coauthor Dr. Trevor Birmingham, Canada Research Chair in the Faculty of Health Sciences and the Bone and Joint Institute at Western University, London, Ontario. "In some ways, it's like performing ...
Solving complex physics problems at lightning speed
2021-02-01
A calculation so complex that it takes twenty years to complete on a powerful desktop computer can now be done in one hour on a regular laptop. Physicist Andreas Ekström at Chalmers University of Technology, together with international research colleagues, has designed a new method to calculate the properties of atomic nuclei incredibly quickly.
The new approach is based on a concept called emulation, where an approximate calculation replaces a complete and more complex calculation. Although the researchers are taking a shortcut, the solution ends up almost exactly the same. It is reminiscent of algorithms ...
Just add mushrooms: Making meals more nutritious
2021-02-01
February 1, 2021 - Researchers have identified another good reason to eat more mushrooms.

Host immune classifier HIC assays may predict treatment response
2021-01-30
(Singapore--4:45 p.m. SPT/3:45 a.m. EST January 30, 2021--Using a host immune classifier (HIC) test for patients with non-small cell lung cancer (NSCLC) may provide better predictors of treatment response and improve outcomes, according to research presented today at the International Association for the Study of Lung Cancer's 2020 World Conference on Lung Cancer Singapore.
Immune checkpoint inhibitors have revolutionized cancer care in patients with advanced stage aNSCLC, but better predictors of treatment response are still needed to guide treatment decisions for patients diagnosed with NSCLC, according to Dr. Wallace Akerley, of Huntsman Cancer Institute in Salt Lake City, Utah. HIC (Host Immune Classifier) is a serum proteomic measure of inflammation. ...
Study finds potential therapeutic targets to inhibit colorectal cancer progression
2021-01-30
Nagoya University researchers and colleagues have revealed that colorectal cancer tissues contain at least two types of fibroblasts (a type of cells found in connective tissue), namely, cancer-promoting fibroblasts and cancer-restraining fibroblasts, and that the balance between them is largely involved in the progression of colorectal cancer. Their findings, recently published in the journal Gastroenterology, suggest that artificially altering the balance between the two types of cells could curb the spread of colorectal cancer tumors, which may become an effective strategy for preventing cancer progression.
Cancer tissues comprise both cancer cells and non-malignant cells such as fibroblasts. Previous studies have suggested that the proliferation of fibroblasts ...
