New approach for solving protein structures from tiny crystals

Using x-rays to reveal the atomic-scale 3-D structures of proteins has led to countless advances in understanding how these molecules work in bacteria, viruses, plants, and humans—and has guided the development of precision drugs to combat diseases such as cancer and AIDS. But many proteins can't be grown into crystals large enough for their atomic arrangements to be deciphered. To tackle this challenge, scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and colleagues at Columbia University have developed a new approach for solving protein structures from tiny crystals.

DNA test is an effective cervical cancer screening tool for women in low-income countries

Cervical cancer is a major issue in low- and middle-income countries due to the lack of adequate screening such as routine Pap smear testing. These countries have high incidences of cervical cancer linked to human papillomavirus (HPV). Due to lack of resources for cancer screenings, these countries account for 85% of all cervical cancer cases.

Match me if you can: Cryptographic breakthrough helps spies to shake hands

When spies meet, they use secret handshakes to confirm their identities, ensuring they are who they say they are. Now, researchers at Stevens Institute of Technology, and colleagues, have solved a 15-year-old problem that allows handshake-style encryption to be used for time-delayed digital communications such as email—a challenge once thought to be impossible.
