Venus might not be a sweltering, waterless hellscape today, if Jupiter hadn't altered its orbit around the sun, according to new UC Riverside research.
Jupiter has a mass that is two-and-a-half times that of all other planets in our solar system -- combined. Because it is comparatively gigantic, it has the ability to disturb other planets' orbits.
Early in Jupiter's formation as a planet, it moved closer to and then away from the sun due to interactions with the disc from which planets form as well as the other giant planets. This movement in turn affected Venus.
COLUMBUS, Ohio - When people have the option to click "like" on a media article they encounter online, they spend less time actually reading the text, a new study suggests.
In a lab experiment, researchers found that people spent about 7 percent less time reading articles on controversial topics when they had the opportunity to upvote or downvote them than if there was no interactive element.
The finding was strongest when an article agreed with the reader's point of view.
Misfolding and aggregation of normally soluble proteins are common pathological features of many neurodegenerative diseases, including Alzheimer's, Parkinson's, Creutzfeldt-Jacob and Huntington's diseases. For example, Parkinson's disease (PD), dementia with Lewy bodies (DLB) and multiple system atrophy (MSA) are characterized by accumulation of misfolded α -synuclein in neuronal and/or glial cells, and therefore these diseases are termed α synucleinopathies.
A recent study published by researchers from the University of Seville shows that university students make excessive use of their mobile phones. The study relates the number of hours that young people spend sitting down, their level of physical activity and state of mind when using a mobile phone. Students with lower levels of physical activity used their mobile phones almost three times more than others. Those reporting poorer sleep quality also used these devices more.
Time may be our worst enemy, and aging its most powerful weapon. Our hair turns grey, our strength wanes, and a slew of age-related diseases represent what is happening at the cellular and molecular levels. Aging affects all the cells in our body's different tissues, and understanding its impact would be of great value in fighting this eternal enemy of all ephemeral life forms.
Steroid hybrid molecules have recently attracted great attention from researchers in recent years owing to their bioactive properties. Earlier a team of researchers led by Dr. Bumal Banik and colleagues, reported the synthesis of several steroid-peptide conjugates of a potential biologically important class of steroid hybrid molecules. During the course of this study, the researchers have come to realize the diverse and interesting biological activities of hetero-steroids.
To circumvent current tobacco advertising, promotion and sponsorship (TAPS) laws in Australia, tobacco companies are incentivising retailers with cash payments, all-expenses paid holidays, exclusive parties and tickets to sporting events to drive tobacco sales.
The Nuffield Council on Bioethics has today published a 'bioethics briefing note' which highlights a pressing need for data on egg freezing success rates to be presented more clearly, accessibly, and transparently. At present, research suggests that women find these data difficult to navigate.
Frances Flinter, Nuffield Council member and Emeritus Professor of Clinical Genetics at Guy's and St Thomas' NHS Foundation Trust, said:
Proven fact: we remember our altruistic behaviour more easily than selfish actions or misdeeds that go against our own moral sense. Described as 'unethical amnesia' by scientists, it is generally explained by self-image maintenance. But could these selective oversights, not necessarily conscious, have a more strategic aim? To find out, a team of behavioural economists from the CNRS (1) recruited 1322 volunteers in an online experiment which took place over two sessions.
To manage and conserve natural ecosystems, it is essential to know how biodiversity changes. As one of those questions, it is important to know whether we are we gaining or loosing species. However, getting reliable measurements to study this is a complex task. Data can be collected by researchers during field trips, but a vast amount of data is also provided by different initiatives such as citizen science programs. However, to ensure measurements are reliable, samples need to be representative of the real world. If samples are not representative, they are biased.
Despite the great advances in cancer research in recent years, treatments that can cause very severe adverse effects are still used. This is the case of neuropathy caused by chemotherapy with platinum derivatives, such as Cisplatin and Oxaliplatin. These are widely used drugs that can damage the peripheral nervous system causing a progressive and increasing loss of sensitivity, which may even affect the mobility. The appearance of these adverse effects may force to reduce the dose or change the treatment for a less effective second-line treatment.
A University of Colorado Boulder astrophysicist is searching the light coming from a distant, and extremely powerful celestial object, for what may be the most elusive substance in the universe: dark matter.
In two recent studies, Jeremy Darling, a professor in the Department of Astrophysical and Planetary Sciences, has taken a deep look at PSR J1745-2900. This body is a magnetar, or a type of collapsed star that generates an incredibly strong magnetic field.
Worldwide, otherwise healthy adolescents and young people without underlying conditions are sometimes severely affected by COVID-19, with the viral infection in the worst cases quickly becoming life-threatening. But why is this happening?
A world-wide consortium of researchers is determined to investigate this - and they have now made so much progress that Science has just published two scientific articles describing some of their results.
Earth could have lost anywhere between ten and 60 per cent of its atmosphere in the collision that is thought to have formed the Moon.
New research led by Durham University, UK, shows how the extent of atmospheric loss depends upon the type of giant impact with the Earth.
Researchers ran more than 300 supercomputer simulations to study the consequences that different huge collisions have on rocky planets with thin atmospheres.
In a paper published in Molecular Frontiers Journal, researchers from Cambridge, Massachusetts have discovered a more effective way of eliminating airborne particles from airways using nasal calcium-rich salts called FEND, which have potential applications in the fight against Covid-19.
