Phys.org / Molecular grappling hooks improve cancer drug targeting and effectiveness
Medications are designed to treat diseased tissues while sparing healthy ones, often by attaching the drug to something that helps guide it directly to its target. But drugs also need time to work, which means they need to ...
Phys.org / Sustainable electrosynthesis enables production of amines directly from airborne nitrogen
Amines are a functional group characterized by the presence of a nitrogen atom bonded to one or more alkyl or aryl (aromatic ring) groups. Derived from ammonia, amines play crucial roles in biological systems and various ...
Phys.org / More selective breeding might help flat-faced dogs to breathe easier
Breeding programs could alter heritable dog characteristics to reduce the rates of brachycephalic obstructive airway syndrome (BOAS), a breathing disorder common in dogs such as Bulldogs, French Bulldogs and Pugs—according ...
Phys.org / Atomic step–terrace ordering enables unprecedented precision in mechanical testing
As modern technologies shrink to the nanoscale, surfaces increasingly dictate how materials deform, yield, and fail. Yet probing this regime has long been hindered by the challenge of preparing and controlling surfaces with ...
Phys.org / 80 years after the Trinity nuclear test, scientists identify new molecule-trapping crystal formed in the blast
Matter behaves strangely under extreme conditions, and often, remnants of these behaviors are left behind even when conditions return to normal. The Trinity nuclear test in 1945 left behind such remnants, and now, 80 years ...
Phys.org / Gravitational waves from colliding black holes may allow detection of dark matter
Dark matter is thought to make up most of the matter in the universe, but the only way it interacts with its surroundings is through gravity. If two colliding black holes spiral through a dense region of dark matter and merge, ...
Phys.org / Gravitational wave detectors can now 'autotune' signals to harmonize the heavens
Gravitational wave researchers working on the world's most sensitive scientific instruments have found a way to tune their detectors using a process akin to the pitch-correction used in music production.
Phys.org / Engineered exosomes reverse sleep deprivation brain damage in mice
Sleep is a vital physiological process that allows humans and other animals to restore both the mind and body, while also consolidating memories, clearing out toxins and regulating their metabolism. Several past studies showed ...
Phys.org / Why are some people mosquito magnets? Clues are emerging
Ever felt like mosquitoes bite you while ignoring everyone else? Scientists are now making progress in deciphering the complex chemical cocktail that makes particular people more enticing to these disease-spreading bloodsuckers.
Phys.org / Bright blazar reveals 433-day optical quasi-periodic oscillation across nine years
By analyzing the data from the Whole Earth Blazar Telescope (WEBT), an international team of astronomers has discovered optical quasi-periodic oscillation (QPO) in a bright quasar known as 3C 454.3. It is so far one of the ...
Phys.org / Meet the whistling mice that use inflatable air sacs to sing
Mice do more than just squeak when they want to make a noise. They can also sing. And the way they do it is different from most mammals that produce sounds by vibrating their vocal cords. When Alston's singing mouse (Scotinomys ...
Phys.org / Work songs can improve team coordination, study finds
Work songs, musical pieces designed to be performed or sung while working, have been widely documented across various cultures and in different historical periods. For instance, people in different nations have been known ...
