Large-scale randomized trial found signs of preventive cardiovascular effects for cocoa flavanols, including a 27 percent reduction in the secondary endpoint of cardiovascular death
From 2004 to 2017, there was an increase in cancer of the appendix in acute appendicitis patients, especially among patients younger than 50 years old.
Patients with impaired immunity have faced a difficult predicament during the pandemic. Their condition places them at risk of severe Covid-19 complications, but until now, no-one knew if they were at higher risk of adverse side-effects following vaccination against Covid-19. A new study trialed two mRNA vaccines in such patients and found that they are safe and well tolerated. The results will help immunocompromised patients in making an informed choice about vaccination.
In a first-of-its-kind study, research from the University of Vermont Cancer Center has linked phthalates, commonly called the “everywhere chemical,” to higher incidence of specific childhood cancers.
Different activity in two molecular networks could help explain why triple negative breast cancers tend to be more aggressive in African American (AA) women compared with white American (WA) women, a new study led by Johns Hopkins Kimmel Cancer Center researchers suggests.
The fossil, housed in The Nat’s paleontology collection, offers a window into what the Earth was like during the Eocene Period, more than 40 million years ago.
You know you should set aside savings with every paycheck, live within your means and invest your money wisely. But do you do it? New research from the University of Georgia suggests that answering three questions could give people insight into their spending and potentially help them modify their behavior in the future.
When the European Space Agency’s Rosetta spacecraft discovered abundant molecular oxygen bursting from comet 67P/Churyumov-Gerasimenko (67P) in 2015, it puzzled scientists. They had never seen a comet emit oxygen, let alone in such abundance. But most alarming were the deeper implications: that researchers had to account for so much oxygen, which meant reconsidering everything they thought they already knew about the chemistry of the early solar system and how it formed. A new analysis, however, led by planetary scientist Adrienn Luspay-Kuti at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, shows Rosetta’s discovery may not be as strange as scientists first imagined.
The return to daylight saving time each spring affects the sleep patterns of millions of Americans and can wreak havoc on the many people already affected by sleep problems. Houston Methodist sleep expert Dr. Aparajitha Verma suggests a few simple sleep habits that can make all the difference when we spring forward March 13.
The antiviral therapies remdesivir, molnupiravir, and the active ingredient in Pfizer’s Paxlovid pill (nirmatrelvir), remain effective in laboratory tests against the BA.2 variant of SARS-CoV-2, the virus that causes COVID-19. The BA.2 variant also remains susceptible to at least some of the monoclonal antibodies used to treat COVID-19, such as Evusheld by AstraZeneca.
There is a scientific reason that humans feel better walking through the woods than strolling down a city street, according to a new publication from University of Oregon physicist Richard Taylor and an interdisciplinary team of collaborators.
Novel device shows promise in reducing anxiety for stressed students.
A new study in the journal Frontiers in Public Health led by scientists from the Wildlife Conservation Society (WCS) confirms that pangolins confiscated from the illegal wildlife trade in Viet Nam host SARS-CoV-2 related coronaviruses.
We all know we should exercise and eat healthy. But doing that isn’t just good for maintaining your figure as you age. New research from the University of Georgia shows that physical activity could help protect your cognitive abilities as you age. And it doesn’t have to be intense exercise to make an impact.
Mindfulness meditation is a stress-management practice with ancient lineage that cultivates nonjudgmental awareness of the present moment, often by directing attention to the physical sensations of breathing. Initially inspired by centuries-old Buddhist practices consisting of philosophies and meditations together, today a secular version of mindfulness — consisting of meditations alone — is becoming increasingly popular.
Working a nontraditional schedule, and checking in at all hours of the day, night and weekends, is not necessarily beneficial for the 21st-century workforce, according to new Cornell University research.
FishSounds.net is the first online, interactive library for the sounds fish make when communicating or interacting with their environment. Fish sounds provide scientists valuable data for studying and conserving underwater ecosystems. An accompanying review study found that just under a 1,000 fish make sounds for communication, though this is likely an underestimate.
It may be possible to identify the presence of an aggressive brain tumor in children by studying their cerebrospinal fluid, according to new research led by Johns Hopkins Kimmel Cancer Center investigators.
The Joro spider first arrived stateside around 2013 and has since spread across the state and Southeast. But new research from the University of Georgia suggests the invasive arachnids could spread through most of the Eastern Seaboard of the U.S.
Many people impacted by COVID-19 experienced changes in their sense of smell, taste, hearing, balance and in some cases, tinnitus, “ringing” in the ears. Among the various causes of tinnitus is stress. What’s unclear, however, is whether the psychological impacts of the pandemic such as stress actually worsened tinnitus. Results of a new study do not support the idea that the pandemic led to a worsening of tinnitus.
Doing less exercise could deactivate a vital protein in the body, causing further inactivity and making exercise more difficult, new research suggests.

A team of scientists used an emerging genetic tool that analyzes DNA in water samples to detect whales and dolphins in New York waters.
Viewing images from childhood reduces pain perception.
People and ecosystems least able to cope are being hardest hit by climate change, according to the latest Intergovernmental Panel on Climate Change (IPCC) report, released today.
Eating meat five times or less per week is associated with a lower overall cancer risk, according to a study published in the open access journal BMC Medicine.
The boreal forest is a belt of cold-tolerant conifer trees that stretches nearly 9,000 miles across northern North American and Eurasia; it makes up almost a quarter of the Earth's forest area. It's also the coldest—and most rapidly warming—forest biome on the planet, and its shifting characteristics amid climate change are raising concerns about increased fire activity, decreased biodiversity and other long-term adverse effects for the human and natural ecosystems.
Astronomers have used a new technique to confirm a real-life Tatooine, the fictional planet with two suns that was home to Luke Skywalker in “Star Wars.”
Patients treated for Merkel cell carcinoma face a five-year recurrence rate of 40%—markedly higher than recurrence rates for other skin cancers, according to new research in JAMA Dermatology. As well, 95% of recurrences happened in the first 3 years, suggesting surveillance should be focused in that span.
The SARS-CoV-2 virus is continuously evolving and structural changes to the virus may impact the efficacy of antibody therapies and vaccines. A study publishing February 17th in PLOS Pathogens by Anshumali Mittal at the University of Pittsburgh, USA and colleagues describes the structural and functional landscape of neutralizing antibodies against SARS-CoV-2 spike protein and discuss the effects of mutations on the virus spike protein that may allow it to evade antibody responses.
Registered dietitian nutritionists can help decrease the number of children diagnosed with overweight or obesity by collaborating with caregivers, educators, health care providers and legislators to provide children with nutritious foods and opportunities for physical activity, according to a new position paper from the Academy of Nutrition and Dietetics.
As the European green crab invasion in Washington state worsens, a new analysis method developed by University of Washington and Washington Sea Grant scientists could help contain future invasions and prevent new outbreaks using water testing and genetic analysis.
New studies emerge daily on the effect of the human microbiome on human health: colon cancer, ulcers, and cognitive conditions such as Alzheimer's disease have been associated with the communities of microbes that live in our bodies.
The source of Earth’s water has been a longstanding debate and Lawrence Livermore National Laboratory (LLNL) scientists think they have the answer—and they found it by looking at rocks from the moon.
Speech recognition technology allows us to ask Siri to check the weather for tomorrow, or to ask Alexa to play our favorite song. But those technologies require audible speech. What if a person can’t speak, or if vocalized speech in a particular setting isn’t appropriate?
The brain’s ability to clear a protein closely linked to Alzheimer’s disease is tied to our circadian cycle, according to research published in PLOS Genetics.
Participants in the study who cycled on a stationary bike or took a brisk walk for an hour-and-a-half after getting a flu shot or COVID-19 jab produced more antibodies in the following four weeks compared to participants who sat or continued with their daily routine post-immunization.
A new paper published in January by Buffalo State College’s Robert J. Warren II, associate professor of biology, and Stephen Vermette, professor of geography and planning, puts a spotlight on how climate change is affecting fruit growers in the Great Lakes refugia, and what it may mean for the growers going forward. The paper, titled “Laurentian Great Lakes Warming Threatens Northern Fruit Belt Refugia,” was published in the International Journal of Biometeorology.
Men with high levels of body fat have lower bone density and may be more likely to break a bone than those with normal levels of body fat, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism.
Scientists have a new understanding of the protective effects of caffeine on the cardiovascular system. While its stimulant effects have long been characterized, a team of McMaster University researchers have discovered how caffeine interacts with key cellular factors to remove cholesterol from the bloodstream.
A study is the first to examine the impact of per-meal protein prescription and nutrition education with and without diet coaching to improve protein intake among middle-aged women. Since protein is the building block of muscles, researchers also investigated the impact of the changes in protein intake on muscle health.
A new model, available as an online calculator, estimates the impact of dietary changes on life expectancy.
Scientists have long hypothesized that climate change, by intensifying stressors like drought or wildfires, would make an ecosystem more vulnerable to invasive plants. Those invasive plants may in turn alter the environment in ways that amplify the impacts of climate change, explained Luke Flory, a professor of ecology in the UF/IFAS agronomy department. A new long-term field study conducted by Flory’s lab offers the first experimental evidence to support this hypothesis.
An analysis of federal health data indicates that people who have had COVID-19 are at increased risk of developing cardiovascular complications within the first month to a year after infection, according to researchers at Washington University School of Medicine in St. Louis and the Veterans Affairs St. Louis Health Care System.
A Johns Hopkins Medicine scientist who spent 30 years figuring out how to put chemical labels into cells to track their movement in living tissues has found that certain self-renewing stem cells have built-in tracers — made out of sugars — that can do the job without added chemical “labels” when injected into mouse brains.
In a randomized clinical trial, overweight adults who increased their nightly sleep duration by about an hour reduced their daily caloric intake by an average of 270 kcal, which would lead to weight loss over time.
A new scientific study shows that all previously proposed body forms of the gigantic Megalodon, or megatooth shark, which lived nearly worldwide roughly 15-3.6 million years ago, remain in the realm of speculations.
Five days of antibiotics is superior to 10 days for children with community-acquired pneumonia who are not hospitalized, according to a study published in JAMA Pediatrics.
New research indicates that a common mosquito species (after detecting a telltale gas that we exhale) flies toward specific colors, including red and orange. Scientists believe these findings help explain how mosquitoes find hosts, since human skin, regardless of pigmentation, emits a red-orange “signal” to their eyes.
Astronomers using Hubble and Keck have identified two different cases of "mini-Neptune" planets that are losing their puffy atmospheres and likely transforming into super-Earths.
