Only recently have astronomers started thinking about potential conflicts between the desire to expand knowledge of the universe on one side and geopolitical rivalries and commercial gain on the other
Australia has just passed a world-first bill that will ban all vapes from general retail later this year.
There’s evidence of maize farming from dry caves in Mexico as early as 9,000 years ago.
The occasion has its roots in the so-called Roswell Incident on July 2, 1947
Everyday clothing may soon be able to capture and record body movements according to new research.
Ever wondered why you performed worse than expected in that final university exam that you sat in a cavernous gymnasium or massive hall, despite countless hours, days and weeks of study? Now you have a genuine reason -- high ceilings.
A world-first study has found low-dose aspirin may treat flu-induced blood vessel inflammation, creating better blood flow to the placenta during pregnancy.
The wild poliovirus is restricted to pockets of Afghanistan and Pakistan, and is beginning to reappear from here in big cities in these two countries
Drugs that selectively kill senescent cells may benefit otherwise healthy older women but are not a 'one-size-fits-all' remedy, Mayo Clinic researchers have found. Specifically, these drugs may only benefit people with a high number of senescent cells, according to findings publishing July 2 in Nature Medicine.
Chemists have discovered a way to use visible light to synthesize a class of compounds particularly well suited for use in pharmaceuticals. The class of compounds, called azetidines, had been previously identified as a good candidate to build therapeutic drugs, but the compounds are difficult to produce in chemical reactions. Now, a team has developed a method to produce a specific class of azetidines called monocyclic azetidines using visible light and a photocatalyst.
In a recent study, researchers suggest the cell's messenger RNA (mRNA) -- the major translator and regulator of genetic material -- along with a critical protein called ZAK, spur the cell's initial response to UV radiation damage and play a critical role in whether the cell lives or dies.
Researchers have developed a new two-photon polymerization technique that uses two lasers to 3D print complex high-resolution structures. The advance could make this 3D printing process less expensive, helping it find wider use in a variety of applications, from consumer electronics to the biomedical field.
Solar panel and biorefinery designers could learn a thing or two from iridescent giant clams living near tropical coral reefs, according to a new study. This is because giant clams have precise geometries -- dynamic, vertical columns of photosynthetic receptors covered by a thin, light-scattering layer -- that may just make them the most efficient solar energy systems on Earth.
A major challenge in developing a vaccine for HIV is that the virus mutates fast -- very fast. Although a person initially becomes infected with one or a few HIV strains, the virus replicates and mutates quickly, resulting in a 'swarm' of viral strains existing in a single body.
A team of researchers had already been working with electricity price data for years before Russia's invasion of Ukraine, exploring statistics and developing forecasting methods. Now they zero in on how prices in different countries relate and how countries were affected by the energy crisis and address the interdependencies of different markets. Their approach combines statistical physics and network science, identifying communities and the fundamental spatiotemporal patterns within the electricity price/time data from all countries. The researchers hope their work will strengthen the European perspective in the political debate about electricity markets and prices, because problems like this are best tackled via international cooperation.
Scientists have identified a gene which, when missing or impaired, can cause obesity, behavioural problems and, in mothers, postnatal depression. The discovery, reported today in Cell, may have wider implications for the treatment of postnatal depression, with a study in mice suggesting that oxytocin may alleviate symptoms.
Randomized controlled trials, or RCTs, are believed to be the best way to study the safety and efficacy of new treatments in clinical research. However, a recent study found that people of color and white women are significantly underrepresented in RCTs due to systematic biases.
Raising the energy state of an atom's nucleus using a laser, or exciting it, would enable development of the most accurate atomic clocks ever to exist. This has been hard to do because electrons, which surround the nucleus, react easily with light, increasing the amount of light needed to reach the nucleus. By causing the electrons to bond with fluorine in a transparent crystal, UCLA physicists have finally succeeded in exciting the neutrons in a thorium atom's nucleus using a moderate amount of laser light. This accomplishment means that measurements of time, gravity and other fields that are currently performed using atomic electrons can be made with orders of magnitude higher accuracy.
A research effort has made advances that could enable a broader range of currently unimagined optoelectronic devices.
