Is anxiety contagious?

A study by Prof. David Eilam and his team found that group members display the same level of anxiety when exposed to a common threat, regardless of individual differences. This result has implications for helping clinicians better treat victims of trauma or terror, such as in the case of the 9/11 attacks.

OCTANE study influences revision of WHO guidelines for treating some HIV-infected women

A new study found that single-dose nevirapine can hamper the drug's effectiveness if used later to treat HIV-infected women. The WHO has revised its guidelines to advise against using nevirapine in combination with other drugs, if treatment begins fewer than 12 months after exposure.

Mysterious pulsar with hidden powers discovered

A team of astrophysicists has observed dramatic flares and bursts of energy from a weakly magnetized, slowly rotating pulsar, challenging the understanding of how these events occur in normal, low-field neutron stars. The discovery indicates that internal magnetic fields may be responsible for powering these phenomena.

Pitt team finds protein that sets the stage for exchanges of DNA code in eggs and sperm

A team led by Judith Yanowitz has discovered a protein that plays a key role in choosing where genetic material gets swapped between maternal and paternal chromosomes during egg and sperm formation. This discovery sheds light on the roots of chromosomal errors and gene diversity, with potential implications for understanding infertility.

A crucial link in immune development and regulation unearthed

Researchers at Monash University have discovered a protein called pre-T alpha that guides the correct expression of T cell receptors, enabling the immune system to effectively destroy harmful viruses and bacteria. The finding has significant implications for understanding immune development and potential treatments for childhood leukemia.

Growing galaxies gently

A team of astronomers has discovered that young galaxies can grow by sucking in cool streams of hydrogen and helium gas, forming new stars. This process, known as accretion, provides a gentler alternative to galaxy mergers, which are thought to be the primary mechanism for galaxy growth.
