Chemists discover why photosynthetic light-harvesting is so efficient
When photosynthetic cells absorb light from the sun, packets of energy called photons leap between a series of light-harvesting proteins until they reach the photosynthetic reaction center. There, cells convert the energy into electrons, which eventu.....»»
Sick of supersized EVs? The 2025 Hyundai Kona Electric hits the spot.
It's not too big, it's not too heavy, and it's very, very efficient. If conventional wisdom were to be believed, the car we're reviewing today should not exist. Automakers are on.....»»

Chiral molecular self-assemblies that absorb light boost singlet fission process, research demonstrates
In organic molecules, an exciton is a particle bound pair of an electron (negative charge) and its hole (positive charge). They are held together by Coulombic attraction and can move within molecular assemblies. Singlet fission (SF) is a process wher.....»»
Astronomers predict the orbits of potentially hazardous comets from meteor showers
Comets have long been seen as omens and portents, and it's easy to understand why. They first appear as faint smudges of light in the sky, sometimes fading soon after and sometimes becoming brighter than the planets, with a long, glowing tail. They h.....»»

Destructive weed, found in New York state, resists common herbicides
The invasive pigweed Palmer amaranth, first found in New York soybean fields in 2019, has been dubbed the "spotted lanternfly of weeds" for its ability to spread quickly and wreak havoc on crops. Now a new study sheds light on how formidable an oppon.....»»
Safe, efficient method for synthesizing allenes opens up new possibilities for drug development
A research team jointly led by Professor Sung You Hong and Professor Jan-Uwe Rohde has unveiled a novel method for synthesizing allenes—a series of compounds integral to drug development and synthetic chemistry—without relying on hazardous, highl.....»»
A novel state of thorium opens the possibility for a nuclear clock
Why are there atomic clocks but no nuclear clocks? After all, an atom's nucleus is typically surrounded by many electrons, so in principle it should be less susceptible to outside noise (in the form of light). A nucleus, for high-atomic number atoms,.....»»
