Planetary systems form out of the remnant gas and dust of a primordial star. The material collapses into a protoplanetary disk around the young star, and the clumps that form within the disk eventually become planets, asteroids, or other bodies. Although we understand the big picture of planetary formation, we've yet to fully understand the details. That's because the details are complicated.
Researchers at the Francis Crick Institute have revealed that CRISPR-Cas9 genome editing can lead to unintended mutations at the targeted section of DNA in early human embryos.

In the latest in their series of investigations on metabolic and bacterial liver disease, researchers from the University of Tsukuba found that people with non-alcoholic fatty liver disease and gum disease benefitted from engaging in regular exercise because it improved their body's own physiology functions and reduced the harmful effects of the bacterial populations residing within the mouth.
Researchers at the University of Tsukuba have shown that an exercise regimen reduces liver steatosis and stiffness in patients with non-alcoholic fatty liver disease. These gains in hepatic health are mediated through modification of inter-organ cross-talk, circulatory organokine alterations and reductions in inflammation and oxidative stress. Because these benefits are unrelated to weight loss, a
GEOGRAFI A new study by a University of Copenhagen researcher finds that thawing permafrost in Alaska causes colder water in smaller rivers and streams. This surprising consequence of climate change could affect the survival of fish species in the Arctic's offshore waters.
How long are you impaired after cannabis use? New analysis defines durations of impairment after inhaled or oral THC doses. The findings raise questions about drug-driving laws that penalise drivers for any THC presence and not impairment.
Understanding how organisms deal with an uncertain future may help identify which species are most vulnerable to climate change and which are best at managing the risk. In a paper published recently in the journal Evolution, Macquarie University ARC Future Fellow Associate Professor Darrell Kemp reveals that no single strategy may prove "best" under such circumstances.
Nästan varannan motionslöpare drar på sig skador. Oftast är det knäna, vaderna eller hälsenorna som råkar illa ut, och riskerna är lika stora oavsett ålder, kön eller löperfarenhet. Det visar en ny avhandling i idrottsvetenskap. Jonatan Jungmalm, doktorand vid Göteborgs universitet, rekryterade drygt 200 motionslöpare från Göteborgsvarvets anmälningsregister och följde dem under ett års tid. För
We have a lot of vaccine news to catch up on! First up is the latest on the possible clotting side effects seen with Oxford/AstraZeneca. This is looking more and more likely to be a rare-but-real effect, and I'm not happy that it's holding up. I had hoped at first that this was a false signal, but as more data have come in, that possibility is fading. The EMA and others have been coming around to
Under året som gått har sjukvården bevittnat allt fler patienter med långtidseffekter av covid-19, bland annat kroniska symtom som tyder på pots. Pots är ett tillstånd som gör att pulsen rusar när man står upp. Hittills vet man för litet om pots som komplikation efter covidinfektion, men forskare från Lunds universitet och Karolinska institutet beskriver nu tre fall av svenska patienter som diagn
Spiders are master builders, expertly weaving strands of silk into intricate 3D webs. If humans could enter the spider's world, they could learn about web construction, arachnid behavior and more. Now, scientists report they have translated the complex structure of a web into music, which could have applications ranging from better 3D printers, to cross-species communication and otherworldly music
A new discovery on the west bank of the Nile, near the iconic Valley of the Kings, has archaeologists buzzing about what may be the most important archaeological find since the location of Tutankhamun's tomb. An entire lost city has been found, with workshops, palaces, a cemetery, and living quarters. The site is said to be in excellent condition. "There's no doubt about it; it really is a phenom
Scientists have been trying for decades to merge the biological and mechanical with limited success. In between tweeting about exploding rockets and electric cars, Elon Musk aims to change that with a company called Neuralink. The secretive company has just released a new video demonstrating its brain-machine link technology. It features a monkey drinking smoothies and playing Pong with its brain
"This is the first demonstration that virulence of human pathogenic bacteria can be mitigated by molecules secreted in probiotic milk products, such as yogurt or kefir," said BGU Prof. Jelinek. "Our research illuminates the mechanism by which milk fermented probiotics can protect against pathogenic infections and aid the immune system. We look forward to administering these drug candidates to pati
The prevalence of Black, non-Hispanic students in high schools that do not offer any AP or IB courses in multi-school districts that fund college-prep curricula cannot be explained by resource or school factors.
The institutional compliance costs of the FAFSA verification mandate in 2014 totaled nearly $500 million, with the burden falling disproportionately on public institutions and community colleges in particular. Twenty-two percent of an average community college's financial aid office operating budget is devoted to verification procedures, compared to 15 percent at public four-year institutions and
New study finds higher medical financial hardship in adult survivors of adolescent and young adult (AYA) cancers than in adults without a history of cancer in the United States. The study appears in JNCI: The Journal of the National Cancer Institute.
Breast cancer survivors who are overweight have a statistically significant increased risk of developing second primary cancers, according to results from a study conducted by Kaiser Permanente researchers and published in the Journal of the National Cancer Institute.
A study investigating a consecutive series of 230 patients with premature onset of heart attacks, strokes, angina or peripheral artery disease and a comparison group shows that family history of early onset cardiac events is a major and independent risk factor in close relatives. Patients with a positive parental or sibling history of premature cardiac events require even more aggressive therapeut
Coastal communities face increasing danger from rising water and storms, but the level of risk will be more closely tied to policy decisions regarding development than the varying conditions associated with climate change.
After controlling for levels of school social disorder and student misbehavior, students attending high-surveillance high schools are more likely to be subjected to in-school suspension than those at low-surveillance schools, have lower math achievement, and are less likely to attend college. Black students are four times more likely to attend a high versus low-surveillance school.
Participating in elementary school gifted programs is associated with reading and math achievement for the average student, though the observed relationships are small. Black and low-income students do not see the academic gains that their peers experience when receiving gifted services.There is no evidence that participating in a gifted program is related to nonachievement outcomes such as studen
While teachers in spring 2020 felt that 60 percent of their students were prepared for the next grade level, in fall 2020 teachers reported that only 50 percent of students had the skills needed to transition to their class when schools reopened. Additionally, 75 percent of teachers reported spending more time reviewing material from the previous grade when compared to prior years.
Over the past 20 years, bachelor's degree completion rates for students who overmatch (i.e., attend colleges that may appear too academically selective for them) have improved substantially. Over the same time period, bachelor's degree completion rates for students who undermatch (i.e., attend colleges that appear too academically unselective for them) and match (i.e., attend colleges that appear
Researchers from the Norwegian University of Science and Technology investigate the degree to which regret regarding sexual encounters makes us modify our behavior. Women more often have regrets about encounters that occurred, while men regret the ones that didn't. According to the study, people keep doing what they've been doing and continue to have the same regrets. When it comes to sexual enco
New research debunks the belief that you can assess intelligence based on facial features. Researchers have identified more than 70 genes that affect variation in both brain and facial structure. The genes don't influence cognitive ability, however. Although developmental biologists are used to thinking about the developing face as a receptacle for the embryonic brain—morphing and stretching as t
Kindergarten children who frequently externalize problem behaviors (i.e., are aggressive or otherwise target their behavior at others) are at high risk of being frequently bullied later in 3rd-5th grades. Children with higher academic achievement and who can better self-regulate their behaviors–two other factors that can be modified–are at slightly less risk of being frequently bullied in later
An international team of researchers led by computer scientists at the University of California San Diego have identified 163 variable number tandem repeats (VNTRs) that actively regulate gene expression. In a paper published in Nature Communications this week, the researchers provide new insights into this understudied mechanism, how it may drive disease and other traits and could ultimately impa
Tidigare forskning har antingen fokuserat på ungdomars mobilitet eller på deras inträde på arbetsmarknaden. Hanna Uddbäck kombinerar dessa två perspektiv. I sin avhandling i arbetsvetenskap vid Göteborgs universitet, undersöker hon varför unga vuxna väljer att stanna kvar i en mindre stad, kopplat till situationen på arbetsmarknaden och övriga livsvillkor. Studien visar att unga ser flera fördelar
Coastal communities face increasing danger from rising water and storms, but the level of risk will be more closely tied to policy decisions regarding development than the varying conditions associated with climate change, new research by Oregon State University suggests.
Do men care about their skin? The answer is "of course", but if you ask men if they care about a personalized skincare regimen that preserves their looks, 64 percent apparently say "no." According to market researcher, Mintel, 64 percent of guys don't consider men's skincare " an important factor " in their daily grooming, which is a shame—men's skin is uniquely different from women's. Because of
Some terms created for science fiction eventually are adopted when the technology they anticipate comes to pass. In this case, we can thank The Six Million Dollar Man for popularizing the term "bionic" which was originally coined by Jack E. Steele in August 1958. The term is a portmanteau of biological and electronic, plus it just sounds cools and does roll off the tongue, so it's a keeper. So wh
Older adults with more harmful than healthy bacteria in their gums are more likely to have evidence for amyloid beta–a key biomarker for Alzheimer's disease–in their cerebrospinal fluid, according to new research from NYU College of Dentistry and Weill Cornell Medicine. However, this imbalance in oral bacteria was not associated with another Alzheimer's biomarker called tau.
Sirry Alang, associate professor of sociology and health, medicine, and society at Lehigh University, and research colleagues examine the three core functions of public health — assessment, policy development and assurance — and the ten recently revised essential public health services (EPHSs) to offer strategies public health professionals can follow to dismantle white supremacy.
Robot vacuums have gone from novelty to ubiquity, and for a reason. They're so useful, people are hacking theirs to fly in order to keep more than one floor clean.

"The idea of a virgin American wilderness—an Eden untouched by humans and devoid of sin—is an illusion. The national parks are sometimes called 'America's best idea,' and there is much to recommend them. They are indeed awesome places, worthy of reverence and preservation, as Native Americans like me would be the first to tell you. But all of them were founded on land that was once ours, and many
Illustrations by Sarah Biscarra Dilley This article is part of a new series called " Who Owns America's Wilderness? " A merica's first national park is only 15 years younger than The Atlantic , and at this magazine we have long told ourselves that our histories are intertwined. That John Muir made his late-19th-century case for the national parks in our pages is part of institutional lore. We are
I jämförelse med vanlig mammografi minskar 3D-mammografi antalet bröstcancerfall som diagnostiseras mellan screeningtillfällena, så kallad intervallcancer. Det visar nya resultat från en stor studie. – Få fall av intervallcancer tyder på att 3D‑mammografi upptäcker cancerfall som annars hade diagnostiserats senare, vid ett eventuellt mer avancerat stadium, säger Kristin Johnson, doktorand vid Lun
Nature Communications, Published online: 12 April 2021; doi:10.1038/s41467-021-22381-z Modern biological research is complicated by the difficulty of collecting, transforming, annotating, and integrating datasets.

Nature Communications, Published online: 12 April 2021; doi:10.1038/s41467-021-22506-4 Human arrival in South America predated the extinction of regional megafauna by a substantial margin, which has suggested a different cause for the extinctions. However, here, the authors show that megafaunal extinctions do correspond to the spread of hunting tools and human population shifts.
Nature Communications, Published online: 12 April 2021; doi:10.1038/s41467-021-22454-z Celastrol might be useful in treating rheumatoid arthritis in part by inhibiting apoptosis of macrophages; however, systemic toxicity is a concern. Here the authors design celastrol-loaded nanoparticles that release a payload in response to MMP9 cleavage and show these NPs are effective at inducing apoptosis of
Nature Communications, Published online: 12 April 2021; doi:10.1038/s41467-021-22379-7 BMI1 and CHD7 are chromatin remodelling genes with a role in medulloblastoma pathogenesis. Here, the authors demonstrate that the BMI1High/CHD7Low signature mediates metabolic adaptation in G4 MB and predicts response to inositol treatment either alone or in combination with chemotherapy.
Nature Communications, Published online: 12 April 2021; doi:10.1038/s41467-021-22433-4 Gamma delta (γδ) T cells have potential for use in immunotherapy against tumours. Here, the authors demonstrate that treatment of tumours with DNA methyltransferase inhibitors modulates cytoskeleton arrangements, upregulates adhesion molecules and increases tumour killing by γδ T cells.
Nature Communications, Published online: 12 April 2021; doi:10.1038/s41467-021-22492-7 As part of two-component systems, diguanylate cyclases (DGCs) are activated by phosphorylation. Structural and computational analyses of DgcR, a model DGC, reveal the phosphorylation-induced conformational changes and the activation mechanism likely shared by many DGCs with N-terminal coiled-coil linkers.

Here, Bi et al. show that a Crh protein from the phytopathogenic fungus Botrytis cinerea acts as a cytoplasmic effector and elicitor of plant defense, and plants expressing this gene exhibit reduced sensitivity to the pathoge
Nature Communications, Published online: 12 April 2021; doi:10.1038/s41467-021-22469-6 RNA m6A demethylase FTO has oncogenic roles in cancers. Here the authors show that chronic low-level exposure of arsenic inhibits autophagic degradation of FTO, leading to FTO stabilisation and reduced m6A RNA methylation in keratinocytes and its subsequent malignant transformation.
Good cholesterol, which is transported in HDLs (high-density lipoproteins), plays a key part in the prevention of atherosclerosis and thus the risk of cardiovascular disease. However, according to a new paper co-authored by researchers at Karolinska Institutet in Sweden and published in the journal Circulation, the anti-inflammatory properties of HDLs could be an even better biomarker for future c
The ability of HDL particles (commonly known as "good" cholesterol) to reduce inflammation in the cells that line blood vessels may help predict who is more likely to develop a heart attack or other serious heart-related event. Gauging the anti-inflammatory capacity of HDL cholesterol may one day improve standard heart disease risk assessment.
A study new surveyed elementary and high schools from 15 different school boards across Ontario to understand the scope of CPR and AED training, which are mandated in the Ontario Grade 9 Health and Physical Education Curriculum. They found that most surveyed schools have an AED installed and 60% offer CPR training to staff. But despite the government mandated curriculum, only 56% of high schools o

Workplace communication often took a back seat this past year, as employees and employers rushed to work remotely, struggled with technology barriers and adjusted to physical distancing. But the pandemic has resulted in valuable lessons for communicating on the job, according to a Baylor University study.
Antivaxxers frequently make the false claim that mRNA-based COVID-19 vaccines "permanently alter your DNA". These claims are really a concern about "impurifying" their "purity of essence". The post first appeared on Science-Based Medicine .

Access to basic necessities such as food, water, electricity, housing, etc should be free in the future when automation replaces most jobs. A UBI can do this, but wouldn't that simply make drive up prices instead since people have money to spend? Rather than give people a basic income to live by, why not give everyone the basic necessities, including excess in case of emergencies? I think it shou
A recent study indicates that a US ban on the use of tanning beds among minors would prevent thousands of cases of melanoma in adolescents and would save millions of dollars in healthcare costs. The findings are published early online in CANCER, a peer-reviewed journal of the American Cancer Society.
People who trust television and Facebook to provide them with accurate news about the coronavirus pandemic are less knowledgeable about COVID-19, according to a new study, which assessed people's knowledge of the virus in the earliest stages of the pandemic.

The COVID-19 pandemic has introduced a number of new behaviours into daily routines, like physical distancing, mask-wearing and hand sanitizing. Meanwhile, many old behaviours such as attending events, eating out and seeing friends have been put on hold. However, one old behaviour that has persisted, and has arguably been amplified due to COVID-19, is sitting — and it is not surprising to see why
Researchers at The University of Texas MD Anderson Cancer Center conducted early phase clinical trials that showed promising results for patients with RET fusion-positive cancers, high-grade and low-grade glioma and ovarian cancer. The results for these studies will be presented at the AACR Annual Meeting 2021.
Playing with a jump rope is something we all did as kids. But as adults, many of us don't realize the tremendous fitness benefits of jumping rope. The fact of the matter is that jumping rope — especially with weighted ropes — is one of the very best ways to exercise your entire body at the same time. And the Crossrope Get Fit Bundle is the best way to get started with this miracle exercise in you
A new study using human genetics suggests researchers should prioritize clinical trials of drugs that target two proteins to manage COVID-19 in its early stages. Based on their analyses, the researchers call for prioritizing clinical trials of drugs targeting the proteins IFNAR2 and ACE2. The goal is to identify existing drugs, either FDA-approved or in clinical development for other conditions, t
