If you've wondered what it costs to go from brunette to platinum blond, we asked someone to break down the price of maintaining the hair color here.

Northwestern University researchers have developed the first selective therapy to prevent allergic reactions, which can range in severity from itchy hives and watery eyes to trouble breathing and even death.

When Jedi Knights need to vanquish an enemy, they whip out their trusty lightsabers. In the future, thanks to Johns Hopkins researchers, doctors seeking to crush cancer may wield minuscule molecular nanoSABERs that allow them to look at tumors in ways never before possible.

What to Buy From Sephora's Sale includes picks from Armani, Dior, Rare Beauty, Kosas, K18, and more.

Researchers have developed a new method that uses antibody fragments encapsulated in nanomicelles which can cross the blood-brain barrier and reduce levels of amyloid-beta in the brains of mouse models of Alzheimer's disease.

An important component of the vaccines protecting people against SARS-CoV-2 virus and its variants are lipid nanoparticles, or LNPs. These circular particles carry therapeutic mRNA payloads, the snippets of genetic material that trigger our immune systems to defend against COVID-19.

Aquaporins, which move water through membranes of plant cells, were not thought to be able to permeate sugar molecules, but University of Adelaide researchers have observed sucrose transport in plant aquaporins for the first time, challenging this theory.

It carries a whopping 171,000 strands of DNA.

In less than 24 hours since the video was posted to Instagram, the clip has generated more than 44,000 likes.

Assemblies of tiny molecular proteins span the membranes that encapsulate our cells, directing cellular activities and regulating the transport of materials and information in and out.

Sometimes the best things in life come by chance, when we happen to be in the right place at the right time. Now, researchers from Japan have found a way to ensure that new medications are delivered to the right place in the body and at the right timepoint in disease progression, so that they have the best effect.

Similar in function to ballast tanks in submarines or fish bladders, many water-based bacteria use gas vesicles to regulate their floatability. In a new publication in Cell, scientists from the Departments of Bionanoscience and Imaging Physics now describe the molecular structure of these vesicles for the first time. These gas vesicles were also recently repurposed as contrast agents for ultrasound imaging.

For decades, figuring out exactly why cancerous tumors form in the human body has been a goal for scientists, but knowing how cancer cells spread is also key to fighting the often-deadly disease.

Olaplex has established itself as an accessible luxury hair care brand that delivers professional-grade results even for its at-home treatments. Take the viral Olpalex No. 3 Hair Repair Perfector, for example. On social media, videos have racked up millions of views showing transformations from lackluster locks to luscious strands. With "perfector" in the name and shocking results, we had to make sure it wasn't too…

Have you ever wondered if bacteria make distinctive sounds? If we could listen to bacteria, we would be able to know whether they are alive or not. When bacteria are killed using an antibiotic, those sounds would stop—unless of course the bacteria are resistant to the antibiotic. This is exactly what a team of researchers from TU Delft , led by Dr. Farbod Alijani, now have managed to do: they captured low-level…

The 2023 Nobel Prize in Chemistry was focused on quantum dots—objects so tiny, they're controlled by the strange and complex rules of quantum physics. Many quantum dots used in electronics are made from toxic substances, but their nontoxic counterparts are now being developed and explored for uses in medicine and in the environment. One team of researchers is focusing on carbon- and sulfur-based quantum dots, using…

A device designed by Johns Hopkins researchers may hold promise for restoring mobility to those with lower limb paralysis

The kola nut tree is grown for its seed. The tree is indigenous to west Africa, where it is widely cultivated. It's now also found in Asia, South America and the Caribbean.

Molybdenum disulfide (MoS2) has recently garnered attention among materials science researchers owing to its ability to form two-dimensional nanosheets like graphene. The nanosheets are created by the stacking of S–Mo–S layers interacting via Van der Waals interactions.

A team of medical scientists at The Catholic University of America, in Washington, D.C., working with a colleague from Purdue University, has developed a way to engineer the bacteriophage T4 to serve as a vector for molecular repair. The study is reported in the journal Nature Communications.
