As Charles Darwin showed nearly 150 years ago, bird beaks are exquisitely adapted to the birds' feeding strategy. A team of MIT mathematicians and engineers…
Being a nocturnal animal, it hunts predominantly with its sense of touch. Professor Michael Brecht (Bernstein Center for Computional Neuroscience, Berlin) now…
Contact with oxygen, in conjunction with the high humidity of the museum environment, causes these contaminants to produce sulfuric acid, according to a new…
This is the main conclusion of the study published in the journal Clinical Nutrition, directed by Professor Josep M. Argilés and co-written by Francisco J….
This new advance involves, after sequencing other plants’ genomes such as the sample species in biological research Arabidopsis thaliana, rice, poplar and…
The substance is composed of a normally inactive derivative of the local anesthetic lidocaine, called QX314, and capsaicin, the pain-producing substance in…
Chinese researchers have recently made a “golden crown” with a diameter of only a few nanometers. It is a large ring-shaped molecule containing 36 gold atoms. The lords of the ring, a team of researchers from the Universities of Beijing, Hong Kong, and Nanjing report their unusual compound in the journal Angewandte Chemie: the molecular ring structure is held together exclusively by gold–gold bonds and is thus the largest ring system made of gold atoms produced to date. …
Viruses need a point-of-entry to a cell, typically binding to an antigen on the cell surface as a means of gaining access. The team, reporting in the March…
In a new study, researchers at the University of Illinois and Columbia University report on how a key motor protein orchestrates chromosome movements at a…
Fertility researchers have used DNA fingerprinting for the first time to identify which embryos have implanted after in vitro fertilisation (IVF) and developed…
“We have shown in animal studies that removing the ALK7 receptor improves insulin release by beta-cells in the pancreas, and at the same time decreases fat…
One aspect of an autistic child’s impaired social abilities is their lack of affiliative behaviors, i.e., behaviors such as touching and hugging that…
They imitated bone formation in embryos and children, which uses cartilage as a template. This new approach appears to be a promising way of repairing bone…
While eating too much and exercising too little are still considered the major cause of obesity, scientists have recently started investigating whether…
But the female concave-eared torrent frog, Odorrana tormota, has a more direct method of declaring her interest: She emits a high-pitched chirp that to the…
