What’s so great about hanging your head out of a car window? (Credit: Shutterstock) If happiness were a picture, there’s a pretty good chance it would be a dog with its head sticking out of a car window. It seems few pups can resist a breeze running through their fur and their ears flapping in the wind as their owner cruises into the sunset. And based on those wind-whipped grins, dogs seem to whol
A rendering of data from the study. The blue shading shows the estimated protocluster extent and the smaller boxes show images of the galaxies they observed in the protocluster. (Credit: NAOJ/Harikane et. al.) Galaxies and dark matter stretch throughout our universe as a vast cosmic web. They cluster together in some areas and leave empty voids in others. But how early in the universe’s history th
The newly discovered planet, named GJ 3512 b, is half the mass of Jupiter. Researchers think its tiny red dwarf host not only likely harbors an additional massive planet, but also ejected another in the past. (Credit: NASA/JPL-Caltech) Astronomers have discovered a gigantic planet orbiting a puny star some 30 light-years away. And according to current theories, the planet shouldn’t exist. Dubbed G
Liquid biopsy is likely to play an increasing role in identifying patients with colorectal cancer (CRC) who are likely to relapse after surgery, and has potential for optimising treatment for individual patients, according to new research presented at the ESMO Congress 2019.
First-line osimertinib significantly lengthens overall survival compared to older generation EGFR-TKIs in patients with Ex19del/L858R EGFR mutated advanced non-small cell lung cancer (NSCLC), according to late breaking results of the FLAURA trial presented at the ESMO Congress 2019 in Barcelona, Spain.
Researchers from The University of Texas MD Anderson Cancer Center reported study results showing that initial treatment with the PARP inhibitor veliparib in combination with chemotherapy significantly increased progression-free survival (PFS) for patients with newly diagnosed, metastatic high-grade serous ovarian cancer, according to the results of the VELIA trial.
An international study shows that administering niraparib after chemotherapy reduces by nearly 40% the risk of relapse or death from this disease. The Primary Investigator is Dr. Antonio González Martín from Clinica Universidad de Navarra (Spain) and president of the Spanish Ovarian Cancer Research Group. The New England Journal of Medicine published this research in its last online issue. Ovarian
New data have shown that first-line treatment with a combination of two immunotherapy drugs improves overall survival in a subset of patients with advanced non-small cell lung cancer (NSCLC) compared to chemotherapy.
New data presented at the ESMO Congress 2019 in Barcelona, Spain, show the benefit of a more intensive maintenance regimen for ovarian cancer with the PARP inhibitor olaparib added to bevacizumab, in an all-comers population, with and without a BRCA mutation. According to late breaking results of the PAOLA-1/ENGOT-ov25 trial, this approach extends progression free survival in patients with advance
In two breakthroughs in the realm of photonics, City College of New York graduate researchers are reporting the successful demonstration of an LED (light-emitting diode) based on half-light half-matter quasiparticles in atomically thin materials. This is also the first successful test of an electrically driven light emitter using atomically thin semiconductors embedded in a light trapping structur
In a paper published today in Nature’s NPJ Quantum Information, Omar Magaña-Loaiza, assistant professor in the Louisiana State University (LSU) Department of Physics & Astronomy, and his team of researchers describe a noteworthy step forward in the quantum manipulation and control of light, which has far-reaching quantum technology applications in imaging, simulation, metrology, computation, commu
The Columbia team behind the revolutionary 3-D SCAPE microscope announces today a new version of this high-speed imaging technology. In collaboration with scientists from around the world, they used SCAPE 2.0 to reveal previously unseen details of living creatures—from neurons firing inside a wriggling worm to the 3-D dynamics of the beating heart of a fish embryo, with far superior resolution and
An international team of astronomers, including Queen’s University Belfast researchers, have made a historic discovery, detecting gas molecules in a comet which has tumbled into our solar system from another star.

(David Goldman/AP Photo/) Flu vaccination prevents millions of flu-related illnesses and deaths annually, but vaccination rates are low for many reasons. During the 2018-2019 flu season, the Centers for Disease Control and Prevention reported that about 45 percent of U.S. adults received the flu vaccine. While this is an increase of 8 perce
Trips to Ikea typically take the crown as the best way to test the strength of a relationship. We know, however, that a day shopping for Swedish furniture has nothing on the crucible of friendship that is Mario Kart . The adorable racing game brings out the brutal competitor in everyone. This week, Nintendo dropped Mario Kart Tour onto iOS, which means mobile users can now red shell all of their
Take care of your jungle. (Scott Webb via Unsplash/) Indoor plants can make any space feel brighter, fresher, and homier. Not only do plants quite literally clean your air, they also add some much-needed greenery to what some may describe as drab city apartments. These essentials are great for any type of plant parent, be that a horticulture newbie or the head of a large family of plant “children
Block the rain and the shine. (Edu Lauton via Unsplash/) An umbrella’s made out of about 150 parts, any one of which could snap and break in a bit of wind. The best umbrellas hold up under storm conditions, are easy to carry, and might look cute, to boot. Here, a few of our favorites. Award-winning windproof umbrella that holds up in storms. (Amazon/) The Repel travel umbrella has nine reinforced
“Hey, that No Red October thing sounds pretty cool! How about you join in?” (Jean Carlo Emer via Unsplash/) For the third consecutive year, here at Popular Science we’re celebrating No Red October, a month in which we suggest you skip the red meat for the sake of our planet . Don’t worry—you won’t be alone in this. Our whole team will embark on this healthy adventure with you, and throughout the
Tasty kombucha, made at home. (Neeks & Gaston via Reshot/) Kombucha, a fermented sweet tea that tastes just a bit like vinegar, has climbed in popularity in the last decade, finding a home in your grocery stores and delis. You may even have a friend who is brewing a batch of their very own. Want to give it a try? Here are some of the materials you’ll want. The Kombucha Shop is a completely organi
A new analysis of Kotzebue Sound fish has found that mercury levels in a variety of its subsistence species are safe for unrestricted consumption. The study tested 297 subsistence-caught fish. The average mercury levels for each of the eight species were at levels considered safe by the Alaska Department of Health and Social Services.
For the first time ever, investigators have identified a washing machine as a reservoir of multidrug-resistant pathogens. The pathogens, a single clone of Klebsiella oxytoca, were transmitted repeatedly to newborns in a neonatal intensive care unit at a children’s hospital. The transmission was stopped only when the washing machine was removed from the hospital.
Soundscapes may influence the evolution of tightly co-evolved host-parasitoid relationships. Both traffic noise and natural ocean noise were found to inhibit parasitoid Ormia fly orientation to sound, which affects reproduction of the fly
